PVC resin FOR CABLE
PVC resin FOR CABLE,
PVC Cable Musanganiswa, PVC Cable Raw Material, PVC Yemagetsi Waya, PVC resin yekuvhara tambo,
PVC nekuti ine yakanaka yemuviri, kemikari, yemagetsi, murazvo unodzoreredza kuita, mu1930s uye 40s, yekune dzimwe nyika yakatanga kushandisa yakapfava PVC sechinhu chekudzivirira waya, kusimudzira uye kushandiswa kwePVC cable zvinhu munyika yedu zvakatanga muma1950s.Nekuvandudzwa kwesimba rekugadzira resin yePVC, plasticizer uye maindasitiri ekuwedzera uye kusimudzira nekushandiswa kwemhando nyowani, indasitiri yetambo ine kusvetuka kwehunhu.
Muzana remakore rechi21, nekuvandudzwa kweruzivo rwezvakatipoteredza uye kutarisa kwevanhu kuhutano hwavo pachavo, nyaya dzezvakatipoteredza dzave chinangwa chevanhu.Nyika zhinji, matunhu nemasangano akagadzira zvimiro zvakaomesesa nemirairo kudzikamisa kushandiswa kwezvinhu zvinokuvadza, kunyanya RolS uye REACH mirau.Kutsvaga nzira itsva uye maitiro matsva, kuvandudza chiyero chekushandiswa kwezviwanikwa, kuenderana nezvinodiwa zvemitemo yekuchengetedza kwezvakatipoteredza uye mirau, kuchengetedza kwezvakatipoteredza PVC cable zvinhu zvakabuda panguva ino, uye nekukurumidza kuva imwe yemadingindira ezvino PVC cable zvinhu kuvandudzwa. .
Iko kuwedzera shanduko uye kuwedzera kwemusika kudiwa kwewaya uye tambo (inonzi tambo), pamwe nekudzidza kwakadzama kwezvakasiyana-siyana zvekuwedzera (senge flame retardant additives, suppressor), kusimudzira kusimudzira nekushandiswa kwezvitsva. matekinoroji, zvinhu zvitsva uye zvigadzirwa zvitsva zvePVC zvinhu.Mune yakawanda organic zvinhu (senge plastiki, rabha) inoshandiswa muindasitiri yetambo, huwandu hwePVC tambo zvinhu ndiyo yekutanga organic zvinhu munyika yedu.
Iyo thermoplastic yakakwira-molecular polymer yakagadzirwa nekumiswa kwepolymerization yevinyl chloride monomer.The molecular formula :- (CH2 – CHCl) n – (N: dhigirii repolymerization, N= 590 ~ 1500).Ndiyo yakanyanya kuwanda mbishi inoshandiswa mukugadzirwa kwepurasitiki.Iine kugadzikana kwakanaka kwekemikari, kusagadzikana kwekuora uye kusagadzikana kwemvura.
