荧光增白剂厂家告:选择增塑剂要注意哪些方面的问题
Fluorescent whitening agent manufacturer's report: What aspects should we pay attention to when choosing plasticizer
如今增塑剂品种越来越多,使得不少初入行的塑料制品企业在选择增塑剂的时分不晓得该如何做选择。上面我给大家引见下选择增塑剂要留意哪些事项:
Nowadays, more and more plasticizers are available, which makes many new plastics enterprises do not know how to choose plasticizers when choosing plasticizers. Above, I'll show you what to pay attention to when choosing plasticizer.
1.增塑剂与树脂间的相容性,普通来说,助剂只要与树 脂间有良好的相容性:才干使助剂临时.波动.平均地存杏 于制品中,无效地发扬其功用,假如相容性不好,则易发作 “出汗”或“喷霜”景象,但有时相容性不好,制品要求不太严厉,依然可以有较差的相容性,如填充剂与树腊间相容 性极差,只需填充剂的粒度小,依然能根本满足制品功能 要求,显然好好用偶联剂或外表活性剂处置,才干充沛发扬其功用。
1. Compatibility between plasticizers and resins. Generally speaking, as long as there is good compatibility between plasticizers and resins, assistants can temporarily fluctuate. Apricots are stored equally in products and their functions are ineffectively developed. If compatibility is not good, they are prone to sweating or frosting, but sometimes the compatibility is not good, so products should be prepared. If the requirement is not too strict, the compatibility between the filler and tree wax is very poor. Only the particle size of the filler is small, it can still satisfy the functional requirements of the product. Obviously, the function of the product can be fully developed by using coupling agent or surfactant properly.
2.增塑剂的耐久性I助剂损失次要经过三条途径挥发,抽出和迁移次要与助剂的分子量大小,在介质中的溶解度及在树脂中的瘠解度有关。
2. The loss of plasticizer durability I additives is mainly volatilized through three ways. The extraction and migration of plasticizers are mainly related to the molecular weight of additives, solubility in medium and barrenness in resin.

3.增塑剂对加工条件的顺应性:某些树脂的加工条伴较苛刻,如加工温度高,时应思索所选助剂会否分解,助剂对模具.设备有否腐蚀作用。
3. Compliance of plasticizers to processing conditions: Some resin processing bars are more stringent, such as high processing temperature, we should consider whether the selected additives will decompose and whether the additives have corrosive effect on the mould and equipment.
4.制品用处对助剂的制约:不同用处的制品对助剂的气息.毒性.电气性.酎候性.热功能等均有一定的要求。
4. Constraints of product use on additives: products with different uses have certain requirements on the odor, toxicity, electricity, strontium weatherability and thermal function of additives.
5.增塑剂配合中的协同作用和绝对抗作用,在同一树脂 体系中,有时其中两种助剂会发生“协同作用〃,比独自各用某一种助剂,发扬效果功用大的多。但是如配合不当,两种助剂间发生“对立作用”减弱每种助剂的功用,甚至使某种助剂得到作用,这点应特别留意,如炭黑与胺类或酚类扰氧剂并用就会发生对立作用。
5. Synergism and absolute resistance in plasticizer combination. In the same resin system, sometimes two of the additives will have "synergism", which is much more effective than using one additive alone. However, if improper coordination occurs, the "antagonism" between the two additives weakens the function of each additive, and even makes some additives work, which should be paid special attention to, such as carbon black and amine or phenolic oxygen disruptors combined will have antagonism.
