CPVC管材管件在使用上的特点及注意事项

CPVC(氯化聚乙烯)的用途很多,比如补强填充体系、稳定防护体系等,下面我们就来了解一下有关氯化聚乙烯之增塑体系。酯类增塑剂是CPE最常用的增塑剂,如邻苯二甲酸二辛酯(DOP)和己二酸二辛酯(DOA),它们的溶解度参数与CM接近,其相容性良好。
CPVC (chlorinated polyethylene) a lot of uses, such as reinforcement filling system, the stability of the protective system, and so on, we come to know about chlorinated polyethylene plasticized system. Ester plasticizer is the most commonly used plasticizer in CPE, such as phthalic acid two octyl ester (DOP) and adipic acid octyl ester (DOA), the solubility parameter of is close to CM, and its compatibility is good.
DOA、DOS用于胶料中可赋予胶料优良的耐寒性。CPVC管材管配件给您介绍几种管材的特点:PEX管特点卓越的耐热耐寒性能,高温下热强度很高优秀的耐低温韧性:加热不熔融超凡的抗蠕变能力:蠕变数据是产品设计和工程选材的重要依据,与金属等传统材料相比,塑料的应变行为对加载时间和温度有着明显的依赖性,PEX管的蠕变特性几乎是常见塑料管中最为理想的管材之一。

CPVC pipe fittings to introduce to you the characteristics of several pipe: PEX tube heat and cold resistance excellent, high temperature high strength, excellent low temperature toughness: creep resistance heating without melting the extraordinary creep data is an important basis for product design and engineering material, compared with the traditional metal materials, plastic strain behavior there are obvious dependence on loading time and temperature, the creep characteristics of PEX tube is almost the common plastic pipe in pipe is one of the most ideal.
CPVC管材加工时的注意事项:
Precautions for CPVC pipe processing:
1、热稳定剂的要求由于CPVC加工温度高,配方中对热稳定剂的用量比PVC高出许多,显然,仅仅使用传统的三盐,二盐热稳定剂是不适合的。目前较为成熟的热稳定剂是具有润滑体系的复合铅系列稳定剂。
1, the requirements of heat stabilizer due to the high temperature of CPVC processing, the formula for the amount of heat stabilizer is much higher than PVC, obviously, only using the traditional three salt, the salt heat stabilizer is not suitable for two. At present, the more mature heat stabilizer is a series of lead compound with lubrication system.
2对润滑剂的要求由于CPVC的熔体粘度很高,特别是在注射成型晨容易发生熔体破裂,所以仅仅使用传统的石蜡、硬脂酸和金属皂类润滑体系是不合适的。在CPVC的挤出加工中,由于CPVC存在一种倾向于粘附在热后加工设备(特别是机头和模具)的金属表面,为了消除这种粘附,必须在配方中加入外润滑剂。外润滑剂与CPVC树脂应该是不相溶的。
The 2 requirement of lubricant due to the melt viscosity of CPVC is very high, especially in the morning to the injection molding melt fracture, so using only the traditional paraffin wax, stearic acid and metal soap lubricating system is not appropriate. In the extrusion process of CPVC, due to the presence of a metal surface which tends to adhere to the hot post processing equipment (especially the die and die), in order to eliminate the adhesion, CPVC must be added to the formula. The outer lubricant and the CPVC resin should not be miscible.
