hard polyvinyl chloride (UPVC) of the injection molding process some of the detailed analysis

UPVC known as hard PVC, vinyl chloride monomer which is formed by the polymerization reaction of amorphous thermoplastic resin and certain additives (such as stabilizers, lubricants, fillers, etc.). pvc called hard pvc, vinyl chloride monomer which is formed by the polymerization reaction of amorphous thermoplastic resin and PVC stabilizer for cable  certain additives (eg stabilizers, lubricants, fillers, etc.). In addition to the additive, but also other resins used for blending with the modified approach
upvc called hard pvc, vinyl chloride monomer which is formed by the polymerization reaction of amorphous thermoplastic resin and certain additives (such as stabilizers, lubricants, fillers, etc.).
In addition to the additive, but also other resins used for blending with the modified approach, it has obvious practical value. These resins are cpvc, pe, abs, eva, mbs like.
upvc high melt viscosity, poor mobility, even when the injection pressure and melt temperature fluidity will not change much. In addition, the resin molding temperature and thermal decomposition temperature are very close to the temperature for forming a very narrow range, is a hard molded material.
1, plastic processing
After 24 hours at room temperature, water less than 0.02%, and therefore without drying. If must be dry, can be placed in 60-70 ℃ hot air oven for 3 hours or 80 ℃ 1-1.5 hours in a dryer.
Up to 20% recycled material and new material mixed, the amount of recycled material depends on the end use of the product. Abuse of recycled material injection can fail, not only the composition of recovered much more is due to the material after repeated re-processing. Every once more recycled material decline in the quality recycling more.
2, injection molding machine selection
upvc Since the melt viscosity, easy PVC heat stabilizer for fittings  to decompose, decomposition products have a corrosive effect on iron, which must be dedicated to the plastics injection molding components and temperature control system.
Ramada products covered in each of the clamping force model, has specialized upvc plastics injection system, and with upvc pipe fittings Pulling requirements with a dedicated security gate devices. Under normal circumstances as long as the injection volume to meet the weight requirements, the choice of this series of injection molding device can be molded upvc high-quality products.
3, mold and gate design
Mold temperature can be set to 40 ℃. Flow channel length should be short, will have a large diameter to reduce the pressure loss and the holding pressure can be passed into the mold cavity. Gate as short as possible, cutting surface to be circular, the diameter of the smallest nozzle orifice 6mm,, into a conical angles to 5 °.
Sprue cutting surfaces have circular, with a combination of cold slug well by connecting section sprue and gate radius, diameter of 7mm.
Gate application tangentially connecting radius of the surface shape plastic parts, the shorter the better, cutting surface to be smooth.
Cold slug well to prevent semi-solidified material into the mold cavity, its importance is often overlooked.
Position of the gate to the right, so that the material in the stream flowing smoothly trail, will not stay in sharp corners, debris and metal traces in order to avoid compression or decompression situation, should maintain smooth flow smoothly.
Application of stainless steel casting mold, chromium content of at least 13%, preferably 16%, at least 55 Rockwell hardness, hard chrome-plated steel mold can be processed to form a protective effect.
After production, the application of a mild lye carefully cleaned and then sprayed mold surface quality oil spray or siliceous spray.
4, the melt temperature
Measure of available air-launched by 185-205 ℃ range. Smoothness of the material from the injection can know the exact upvc melt temperature. If the material in the injection after the rough, as evidenced by the material is not homogeneous (plastics insufficient), which means that the temperature set too low; eg, injection newcomer bubble and smoke  low molecular polyethylene a lot of smoke, it means the temperature is too high.
5, the injection speed
Slower rate of fire, or cause excessive shear degradation of materials, the use of upvc produce extremely smooth, thick-walled products should be used multi-stage injection mold filling speed.
6, the screw speed
Should match the molding cycle may be. Screw face velocity shall not exceed 0.15-0.2m / s
7, the back pressure
Up to 150bar, the lower the better, common to 5bar.
8, the retention time
At a temperature of 200 ℃, barrel residence time can not exceed five minutes. When the temperature is 210 ℃, cylinder residence time should not exceed 3 minutes.

soil conditioner aluminum sulfate salts

Aluminum sulfate in chemistry are acidic chemicals , mainly based on the acid chemical neutralization with a base , for the neutralization of alkaline soils adjusted . Commonly known as acid-base regulation. We look at what is soil pH and aluminum sulfate how to adjust carbon black powder  the soil pH .
Soil pH
 Soil there are various chemical and biochemical reactions , exhibit different acidic or alkaline. The strength of the soil pH , often to measure pH . The reason why the soil pH is due to the presence in the soil small amount of hydrogen ions and hydroxide ions. When the carbon black  hydrogen ion concentration greater than the concentration of hydroxide ions , the soil is acidic ; otherwise alkaline ; two are equal , compared with neutral .
Aluminum sulfate soil conditioner
 The active aluminum aluminum sulfate is adsorbed on the soil colloids exchangeable aluminum and aluminum sulfate of aluminum ions in solution , which is an important ecological factor , the distribution of natural vegetation , have a significant impact on growth and succession ; in strongly acidic soils in aluminum and more, living in this type of soil on plants are often resistant aluminum or aluminum -hi ( broom Shi Lan , tea ) ; but dibutyl phthalate  for some plants , the aluminum is toxic , such as clover , alfalfa, aluminum -rich soil growth inhibition . Therefore, some plants are not suitable for use on alkaline soil aluminum sulfate to adjust , you can adjust the switch to ferrous sulfate , ferrous sulfate can also add iron plant .
In addition, with respect to alkaline soil , there is bound to acidic soils , too acid or base are easy to cause harm to the growth of plants . In acidic soils , generally everyone is familiar with will be used to adjust the lime on lime soil conditioner , I will in the next article will be a brief introduction.

retention aid relationship with aluminum sulfate

Aluminum sulfate manufacturers have reported , aluminum sulfate is paper sizing agent is soil conditioning neutralizer , flocculation and sewage treatment flocculants . The retention aid is used to improve the wire section of paper fibers and fines retention of the Metal stearate  chemical. Then they existed before what kind of relationship do ?
Common retention aids
 Retention aids are commonly modified starch and synthetic resins, retention agents generally also have to accelerate the slurry treatment filter aid performance. There are two main types . ( 1 ) modified starch . From corn , potato , tapioca wet , dry process obtained anion and cation -modified starch. Mainly quaternary ammonium and methyl tin stabilizer  amine -modified cationic starch . ( 2 ) polyacrylamide . Are generally anionic or cationic modified type of product . Anionic polyacrylamide by partial hydrolysis reaction or sulfomethylation reaction. Or by acrylic acid cis -butadiene copolymer derived. Cationic Hoffman is through Mannich reaction or reaction. Also with aminoalkyl methacrylate copolymer obtained .
Aluminum sulfate retention aid
Generally, there are inorganic retention agents such as aluminum sulfate , sodium aluminate ( retention effect chrome oxide  is not significant ) ; cationic starch ; carboxymethyl cellulose ; synthetic resins ( e.g., polyethylene imine , polyacrylamide , polyethylene oxide , polyamides , etc. ) .
  That aluminum sulfate with the fiber retention effect , which means it is a retention aid . This is similar to its role in wastewater treatment . However, its retention effect as polyaluminum chloride and polyacrylamide .

processing aids in the characteristics of different processing methods

Processing aids action principle : PVC melt poor scalability , easily lead to melt broken ; PVC melt relaxation is slow, easily lead to the product surface rough, dull and shark skin and  titanium dioxide anatase so on. Therefore , PVC processing often necessary to add processing aids to improve the melt of the above-mentioned drawbacks . Processing aids as a class can improve the performance of resin processing aids, which consists of three main modes of action : promoting resin melt , the melt rheology modifiers and gives lubrication. 1 PVC resin promoting resin is melted when heated under shear force , processing modifier first melted and adhered to the surface of the PVC resin particles , based on their compatibility with the magnesium hydroxide flame retardant  resin and the molecular weight, the viscosity of PVC and friction increases, thereby effectively the shear stress and heat transfer to the PVC resin, PVC accelerate melting . (2) has a melt rheology modified PVC melt strength is poor, poor scalability and melt fracture and other shortcomings, while processing modifier can improve the melt above problems. Its mechanism of action is: to increase the melt viscoelasticity of PVC , thereby improving the die swell and increased melt strength. 3 gives lubricity compatibility with PVC processing modifier part first melting molten play a catalytic role ; partly incompatible with PVC molten resin to migrate outside the system , thereby improving mold release . ACR processing aids commonly used species category , ACR is methyl methacrylate . PVC can be  plastic additive added to improve the melt strength and melt elongation . ACR-201 is mainly used for rigid PVC profiles , pipes, bottles and sheets, the amount of 0.5 to 2 parts . ACR-401, methyl methacrylate , ethyl acrylate , butyl acrylate and styrene monomer from four kinds , are core - shell copolymers , AMS class , AMS -based oligomeric α- methyl styrene material , which is also called hexamer M-80, it is non-toxic and transparency , and can improve the processability of PVC resistance and luster of products . AMS for rigid PVC , the hard tube add 2 to 5 parts , 3 parts of a transparent film , was added 10 parts of the floor . Copolymers of butadiene and acrylonitrile P83 , the surface treatment by the PVC latex , can be used as processing aids, added in an amount up to about 20 parts . 820-G is a chlorinated paraffin and polypropylene oxide - ethylene made ​​by free radical grafting , which can improve the processability of PVC , gloss and feel, added in an amount up to 5 to 10 parts .

plastics processing aids Main Profile

The main reason is that this growth to continue in the alternative plastic materials traditional materials such as metal , wood, and minerals. In fact , various additives in the resin for the  fluorescent brightener successful application of plastic materials are of great help. In the use of various types of additives to the polymer impact modifiers and processing aids for the  polymer to provide the most unique and most valuable superior performance , but also improve the processing performance of the product . Toughening treatment, rheology control , beautiful appearance , processing performance , and economic factors that are important to the nature of the property . Many of these additives have been used for many years , after a long development derived from a wide range of varieties. A major reason for barium stearate  this situation is the emulsion polymerization process varied, which makes scientists continue to design suitable polymer components , polymer structure , polymer morphology and molecular weight / weight distribution . Low cost of production , and the resulting product is easy to separate the emulsion , therefore , in the commercial production of emulsion polymerization is very attractive . Subsequent to a variety of acrylic processing aid and an acrylic impact modifier . Initially , these additives are primarily used to improve the polyvinyl chloride (PVC) processability and toughness. And processing aids for PVC mainly to promote fusion of PVC , to enhance the melt strength , to improve the dispersion properties and surface quality. High molecular weight PVC foam processing aid is an important component. Means of processing aids , PVC foams can be obtained in a more homogeneous foam structure , and to reduce the breakdown of closed cell foam density will be lower . Act as a lubricant processing aids can effectively prevent the molten plastic bonded to the tin stabilizer  metal surface to improve the surface quality of products , improve production efficiency.
There are many applications of plastic materials is very limited , because they either do not have the required physical properties , or its processing performance is very poor , processing aids, is used to enhance the plastics melt processing, increase production, reduce parking maintenance time and provide better quality products . According to the type of functionality , processing aids can be divided into flux , melt rheology modifiers , lubricants and dispersing accelerator. In fact , each type of processing aids and have more than one effect. Any one processing aid functionality and application results to be dependent on its chemical composition , the polymer structure, molecular weight and type of the polymer matrix .

Some important flame

 Flame retardant; can increase the flame resistance of the material called material flame retardant. Most of them are of the Periodic Table V, VII and compound III element burning rate: the sample unit of time means the length of the combustion. Synergistic effect: refers to two or more of the additives used in conjunction with, the total effect is greater than when used alone, the sum of the individual effects. Synergy system: the Metal stearate  complex flame retardant with the interaction between the use and thus to improve flame retardant performance system called synergistic effect. Synergy systems commonly antimony - halogen system, phosphorus halide system, phosphorus - nitrogen system. Burning speed: samples per unit time  glyceryl monostearate is the length of the combustion. Burning velocity combustion method with horizontal and vertical burning method to measure, too. Oxygen index: is the sample continued to burn like a candle shape when in a nitrogen - oxygen mixture stream in the oxygen content to a minimum. External friction: polymer materials in the molding process, the polymer melt and the friction between the surface processing equipment. Internal friction: forming polymer materials, the molten polymer intermolecular friction. Lubricants; polymer to reduce internal friction and external friction, improved flow of plastic melt, prevent processing of polymeric materials sticking to the equipment, to ensure surface smoothness of the added substance called lubricant. Lubricants: before the ingredients in the plastic processing, the added polymer has a compatibility with a lubricant, and uniformly dispersed into the material, the resin can reduce the friction between the molecules sky lubrication. External lubrication in  tio2 rutile two ways: one is the time of molding of the polymer material, the lubricant coated on the surface of processing equipment, so that in the melt processing temperature and the metal surface to form a "thin layer" will plastic melt and processing equipment to isolate, without adhering to the device, easy stripping or separating roller; Another is the compatibility with the polymer is very small, in the process it is easy to migrate from the polymer inside On the surface, thereby forming an isolation layer of the material, in the processing of the ingredients are added to and dispersed in the plastic, and in the process of migration to the surface, the grease. Release agent: for processing mold and material to be processed completely remain chemically inert substance known as release agent. Foaming; blowing agent can be in a class within a certain viscosity liquid rubber or plastic state, porous structure of the material formed of plastic

Processing aids Some simple instructions

Many of the same means, a simple structure repeating units connected by covalent bonds formed by the high molecular weight (usually up to 104 ~ 106) compound. Such as polyvinyl chloride molecule is composed of many molecules of vinyl chloride repeating structural unit-ch2chcl-concatenated, so-ch2chcl-also known as structural units or segments. Structural units can be formed by a small molecule composed of compounds known as monomers, synthetic polymer materials. Polyvinyl chloride can be abbreviated to:
n represents the number of repeating units, also PVC window stabilizer  known as polymerization degree of polymerization of the polymer is a measure of an important indicator. A low degree of polymerization (1 to 100) of the polymer is called oligomers, only when the molecular weight of up to 104 to 106 (such as plastic, rubber, fiber, etc.) to be referred to as polymers. Made of a polymer by polymerization of monomers called homopolymers as described above, polyvinyl chloride, polyethylene and the like. Copolymerizing two or more monomers from the polymer is called copolymers, such as vinyl chloride - vinyl acetate copolymer. So that natural rubber into practical engineering materials research has made key progress. baekeland reported the synthesis of a thermosetting phenolic resin, this conclusion is the establishment of modern polymer science foundation. Since the establishment of the concept of macromolecules decades, synthetic polymers and achieved rapid development, many important polymers have achieved industrialization. Classification of polymers from different angles can be classified on the polymer, such as oxidized PE WAX  from a single source, synthesis method, the end use, the heating behavior of the polymer structure. (1) according to the molecular structure of the main chain of the elements can be divided into the carbon chain of the polymer, mixed chain and organic elements into three categories.
The polymer main chain carbon chain molecules composed entirely of carbon atoms. Most vinyl and diene polymers fall into this category, such as polyethylene, polystyrene, polyvinyl chloride, etc. Hetero-chain polymer molecules, in addition to carbon atoms in the main chain, there are titanium dioxide  oxygen, nitrogen and sulfur heteroatoms. Such as polyether, polyester, polyamide, polyurethane, polysulfide rubber. Plastics, synthetic fibers, heat-resistant polymer is mostly mixed chain polymer. Macromolecular organic elements no carbon atoms in the main chain, mainly composed of silicon, boron, aluminum and oxygen, nitrogen, sulfur, phosphorus atoms, but the side groups was formed by the organic group such as methyl, ethyl, vinyl group. Organic silicone rubber is a typical example.
Organic elements, also known as semi-organic hybrid polymer chain, the main chain and the side groups if no carbon atoms, it becomes the inorganic polymer.
(2) the nature and purpose by material classification, can be divided into high polymer plastics, rubber and fibers.
