How to analyze PVC compound stabilizer: liquid ba-zn compound stabilizer liquid ba-zn compound stabilizer is generally light yellow to brownish yellow oily liquid, with a specific gravity of 1.0 to 1.1 at room temperature, excellent heat resistance, free from sulfide pollution, and epoxy plasticizer can be used to improve the stability effect, and the foaming agent has the activation effect. Liquid calcium zinc compound stabilizer liquid calcium zinc compound stabilizer mainly become calcium ricinoleate, zinc ricinoleate, calcium stearate, zinc stearate and ultraviolet absorbent, epoxy soybean oil and so on. Liquid calcium zinc complex safe agent is generally choose easy dissolve in organic solution of salt, fat, calcium salt and zinc as composition is different, there are must have difference nature, generally are clear light yellow to yellow oily liquid, temperature ratio between 1.0 to 1.05, the first vessels used for food packaging film, foam PVC leather and so on.

(pictured in a liquid calcium zinc complex safe agent composition - calcium stearate) liquid barium cadmium zinc compound safe agent barium cadmium zinc compound safe agent first used in soft PVC products processing, the basic composition of barium salt, chromium salt, zinc salt, phosphite ester and a handful of liquid ash, white oil, diesel oil, spindle oil, such as mineral oil, the other should also attend a few higher alcohols such as antifoaming agent. The composition of liquid barium, cadmium and zinc compound stabilizer is different, so the properties are also different, the color is generally light yellow to yellow clear liquid, the specific gravity is 0.95 to 1.02 at room temperature, the viscosity is less than 100 cm, the condensation point is about -15℃. Liquid barium cadmium zinc compound stabilizer has excellent light, heat stability, outstanding transparency and color stability, will not attack dust poisoning, and in the general plasticizer can be completely dissolved, with outstanding inattention, small tendency. Lead salt compound security agent because of its good thermal security function, lead salt compound security agent has been widely used, but because its dust is easy to be inhaled lead poisoning, so the scientific research institutions developed a new type of compound lead salt thermal security agent. This new type of compound lead salt thermostability agent chooses the symbiotic reaction technology, the three salt, two salt and metal soap in the reaction system with the initial ecological grain size and a variety of lubricants to mix, not only to ensure that the thermostability agent can be in the PVC system full and relaxed, together to avoid the poisoning caused by lead dust.
