Nekuti pvc resin ine yakanaka yemuviri, kemikari, yemagetsi, inodzoreredza moto, muma1930s uye 40s, kunze kwenyika yakatanga kushandisa PVC yakapfava sechinhu chekudzivirira waya, kusimudzira uye kushandiswa kwePVC cable zvinhu muChina kwakatanga kuma1950s.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.
PVC cable material inoumbwa ne polyvinyl chloride resin, stabilizer, plasticizer, filler, lubricant, antioxidant, colorant zvichingodaro.
PVC plastiki nekuda kwekupisa kwayo, mafuta kuramba, corona resistance, chemical resistance resistance uye mvura yakanaka kuramba, saka inoshandiswawo zvakanyanya sechinhu chinodzivirira waya netambo.Nekuwedzera akakosha ekuwedzera ekuita kana ma modifiers, anodzivirira kupisa (105 ℃), isingatonhore, inodzivirira mafuta, inodzivirira murazvo, yakawedzera-yakapfava uye isina chepfu PVC cable zvinhu zvinogona kugadzirwa zvichiteerana kuti zvizadzise zvinodiwa newaya yakakosha uye zvigadzirwa zvetambo.

Polyvinyl chloride (PVC) plastiki ipurasitiki ine-multi-component, zvinoenderana nemamiriro akasiyana-siyana ekushandiswa, nekushandura akasiyana uye dosage yemumiriri wakaoma, inogona kugadzirwa nemhando dzakasiyana dzePVC plastiki yewaya netambo.Polyvinyl chloride (PVC) tambo yepurasitiki maererano nekushandiswa kwayo muwaya uye tambo, inogona kukamurwa kuita insulation level cable zvinhu uye yekudzivirira level cable zvinhu.Chiyero chekudzivirira chinoda kumira zvakanaka kwekupisa, uye nhanho yekudzivirira inoda yakanaka insulation.
