PVC stabilizer should be noted that some of the problems
Production of paint color retention stabilizer made six major advantages:
A coating applied to the construction process scratch easily without effort, good polishing.
After two dry smooth and delicate, jade hand touch, side as a mirror.
3 hardness is hand draw trace.
4 water resistance, washing powder can not afford a hundred times without cracking. Not from powder using a decade, two decades can not block.
5 No yellowing, PVC stabilizer bright color, good whiteness.
6 powder coating can be resolved using the WSD Stabilizers for pipe blur, yellow major problem. (Dry, add water while stirring, to join together the raw
materials and water, one hundred kilograms plus 300 grams of finished paint color retention stabilizer, stir, to construction.)
Instructions for use:
Before a first add ingredients of water, ash and calcium PVA glue, three raw materials are mixed and stirred for 5 - 10 minutes,
stop the rotation of the stirrer was slowly added color retention stabilizer be added after all the added powder and other Flying
raw materials.
After adding 2 per ton of raw materials on the basis of your original finished paint plus 100 - 200 kg Flying powder, the use of
this raw material in production to try to make a thick, dust ourselves, plus thick prevail. Paint will be more easy to use, easy
sliding profits do not turn the knife, a good collection of light.
3 additional insurance required per ton of WSD Metallic stearate finished paint color stabilizer summer 1 - 2 kilograms, can Paul 3 - 6 months does not
fade, the temperature at 25 degrees Celsius or less insurable year does not fade, its biggest advantage is the last light in color , became white paint, but also to extend the storage period of one year.
Note: A raw material can not and citric acid, PVC stabilizer in combination with borax, make sure to shake well before using this
product, do a small experiment and then put into production, production in proportion to the number of data to be accurate.
Two materials are chemical products, corrosive to the WSD PVC stabilizer skin, do not directly touch.
3 according to the number of recipes using the plant ash calcium, calcium and more with gray color retention stabilizer on, the
longer the more you add color retention time, but do not use too much harm. Our conservative figures, plus a tonne of finished
paint color retention Stabilizer 1 - 2 kilograms best, more color, more weight, color retention time will be longer.
4 material to cool and ventilated, kept at room temperature; away from heat, sun exposure is strictly prohibited.

What are the advantages of PVC stabilizer
Advantages: the same as a heat stabilizer, a lead compound PVC material without compromising the excellent electrical properties,
low water absorption and outdoor weatherability. Disadvantages: Toxic; would cross contamination; generate lead chloride, forming
streaks on finished products; than Stabilizers for pipe significant; immediately so often lead stabilizers in PVC products become opaque, and soon after
continuous heat discoloration. With the ban of lead, "Twelve Five" period while the proportion of lead stabilizers in PVC heat
stabilizers will be reduced year by year. Metal soap stabilizer monomer salt (acid salts): zinc stearate, barium stearate, calcium
stearate, lead stearate, cadmium stearate Metal soap Aluminum hydroxide salt composite stabilizer: calcium zinc stabilizers, barium zinc stabilizer, barium cadmium stabilizers, barium cadmium
zinc stabilizer organic tin stabilizer
Advantages: PVC stabilizer organotin heat stabilizers for the most efficient, transparent and non-toxic products in the most widely
used of a class, its outstanding advantages: good thermal stability, transparency, and most of the non-toxic.
Disadvantages: PVC stabilizer high prices, no lubrication.
Most of the liquid organic tin, only a few PVC plasticizer solid. May be used alone, often with a metal soap. Rare Stabilizer: no lubrication,
should join with the lubricant, the current production of rare earth compound stabilizer is rare, heat stabilizers and lubricants
compound formed, the amount is usually 4-6 copies. Another class of organic antimony stabilizer, a liquid stabilizer.

The main ingredient of PVC stabilizer
PVC stabilizer on the original white and gradually turn yellow - red - brown - black. PVC resin decomposition reaction is due to the de-HCL caused a chain reaction, leading to macromolecules strand breaks. PVC heat stabilizers to prevent thermal decomposition mechanism is through the following aspects to achieve. (1) by capturing the thermal PVC lubricants decomposition of PVC HCl, to prevent catalytic degradation of HCl. The main mechanism of action of lead salts class here, in addition to metal soaps, organic tin, phosphorous lipids and epoxy 2) replacement lively allyl chloride atoms. Metallic soaps, lipids and organic phosphorous tin can here the role of the mechanism. 3) the reaction with free radicals, the radical termination reaction. Organic tin and phosphorous lipid mechanism role here. (4) with conjugated double bond, inhibit growth of conjugated chain. Organotin role and PVC plasticizer mechanism of epoxy here. (5) the decomposition of peroxide to reduce the number of free radicals. Organic tin and phosphorous lipid mechanism role here. 6) HCl passivation effect of a catalytic metal ion removal. PVC stabilizer with a stabilizer according to several different mechanisms to achieve thermal stability purposes. Composite stabilizer can be divided into the following categories: (1) liquid barium zinc composite stabilizer is generally pale yellow to yellow-brown oily liquid, specific gravity 1.0-1.1, good heat resistance at room temperature, without sulfide pollution, and epoxy plasticizers and stabilizing effect can be improved by, it can activate the foaming agent. 2 main Polyethylene wax ingredient liquid calcium zinc composite stabilizer nontoxic liquid calcium zinc stabilizers are calcium stearate, castor oil, calcium, zinc stearate, castor oil, zinc and epoxy soybean oil, ultraviolet absorber. Hugh liquid calcium zinc stabilizers are generally used more soluble in organic solvents having a carbon number of less fat fat calcium and zinc. Because of the different components, varied in nature, usually pale yellow to yellow clear oily liquid at room temperature gravity of 1.0-1.05. It is non-toxic PVC stabilizer, mainly for food packaging films, containers leather foam stabilizers.
