PVC电缆料造粒机纯净的聚***,只是一种白色的粉未,也就是说它只是一种高分子树脂,不能用于直接加工产品;由于合成工艺路线的不同,这种树脂粉一般分为两类:一种是疏松型树脂,另一种是紧密型树脂。我们常用的聚***胶料都是颗粒状的,它是多组份的塑料,除了前面讲的聚***树脂粉以外,还必须加入增塑剂增加它的流动性,加入稳定剂提高它的热稳定性,加入润滑剂提高它的脱模性,以及填料,着色剂,偶联剂等;因为各组份的含量不同,就形成了各种机械性能差异很大的不同硬度的PVC颗粒;它一般用IP度数表示;PVC颗粒大体分为:软质PVC,硬质PVC。外观因PVC胶料所含的组份不同,它的外观差异很大。有的透明如玻璃,也有不透明的;有的非常柔软,耐折迭,有类橡胶弹性;也有硬质的,象ABS,机械性能优良,可以做工程材料。大部分的PVC有轻微毒性,但不致于一接触就能***;也有食品级的PVC胶颗粒。燃烧特征PVC难燃,离火即灭;但燃烧时,火焰上端呈***,下端呈绿色(绿色是氯离子的特有色谱),冒白色烟雾(白色烟雾是HCL气体与水结合的产物);燃烧时,胶料发软,同时,发出刺激性的气味。PVCplasticgranulatorPurepolyvinylchlorideisonlyawhitepowder,whichmeansitisapolymerresinandcannotbeusedfordirectprocessingofproducts.Duetothedifferentsyntheticprocessroutes,thiskindoftreepowderisgenerallydividedintotwotypes:oneislooseresinandtheotheriscompactresin.WeoftenusethePVCplasticmaterialisgranular,itismoreplasticcomponents,inadditiontospeakinfrontofthePVCtreepowder,mustalsojoinplasticizerincreaseitsliquidity,addstabilizertoimproveitsthermalstability,addlubricanttoimproveitsrelease,aswellasthepacking,colorants,couplingagent,etc.;Becausethecontentofeachcomponentisdifferent,thePVCgranuleswithdifferenthardnessareisgenerallyexpressedbyIPnumber;PVCparticlesaregenerallydividedinto:softPVC,hardPVC.Theappearanceisverydifferentduetothedifferentcomponentsofmeareglassyandopaque;Someofthemareverysoft,folding,andrubberelastic;Alsohasthehard,elephantABS,themechanicalpropertyisgood,candotheengineeringmaterial.MostPVCismildlytoxic,butcanbetoxicwithoutcontact;TherearealsofoodgradePVCglueparticles.TheburningcharacteristicPVCisdifficulttoignite,andthefireisextinguished;Butwhenitburns,theupperendoftheflameisyellow,andthelowerendisgreen(greenisthecharacteristiccolorofchlorideion),andwhite***oke(white***okeistheproductofthecombinationofHCLgasandwater).Whenburned,thegelissoft,andatthesametime,itemitsapungentodor,likehydrochloricacid.)
