Polyvinyl chloride (PVC)filastik abu ne mai haɗe-haɗe da aka yi ta hanyar haɗa guduro PVC tare da ƙari daban-daban. Yana nuna kyawawan kaddarorin inji, juriya na lalata sinadarai, halaye na kashe kansa, juriya mai kyau na yanayi, mafi girman kaddarorin wutar lantarki, sauƙin sarrafawa, da ƙarancin farashi, yana mai da shi kayan aiki mai kyau don suturar waya da na USB da sheathing.
Guduro PVC shine polymer thermoplastic na linzamin da aka kafa ta hanyar polymerization na vinyl chloride monomers. Sigar tsarin kwayar halittarsa:
(1) A matsayin polymer na thermoplastic, yana nuna kyakkyawan filastik da sassauci.
(2) Kasancewar C-Cl iyakacin duniya shaidu yana ba da guduro mai ƙarfi polarity, sakamakon in mun gwada da high dielectric akai (ε) da dissipation factor (tanδ), yayin da samar da high dielectric ƙarfi a low mitoci. Waɗannan igiyoyin igiya kuma suna ba da gudummawa ga ƙarfin intermolecular ƙarfi da ƙarfin injina.

2.Nau'in Gudun PVC
Hanyoyin polymerization na PVC sun haɗa da: polymerization na dakatarwa, polymerization emulsion, polymerization mai girma, da kuma polymerization bayani.
Hanyar polymerization na dakatarwa a halin yanzu ita ce mafi girma a samar da resin PVC, kuma wannan shine nau'in da ake amfani da shi a aikace-aikacen waya da na USB.
An rarraba resins-polymerized PVC resins zuwa nau'i biyu na tsari:
Resin nau'in sako-sako (nau'in XS): Halaye da tsarin porous, babban abin sha na filastik, plastification mai sauƙi, kulawar sarrafawa mai dacewa, da ƙananan ƙwayoyin gel, yana mai da shi zaɓin da aka fi so don aikace-aikacen waya da na USB.
Karamin irin guduro (nau'in XJ): Ana amfani da shi don wasu samfuran filastik.
3.Key Properties na PVC
(1) Lantarki Insulation Properties: A matsayin mai matukar iyakacin duniya dielectric abu, PVC guduro nuna kyau amma dan kadan kasa da lantarki rufi Properties idan aka kwatanta da wadanda ba iyakacin duniya kayan kamar polyethylene (PE) da kuma polypropylene (PP). Ƙarfin juriya ya wuce 10¹⁵ Ω·cm; a 25 ° C da 50Hz mita, dielectric akai-akai (ε) yana fitowa daga 3.4 zuwa 3.6, yana bambanta da mahimmanci tare da canje-canjen zazzabi da mita; Matsakaicin lalacewa (tanδ) ya tashi daga 0.006 zuwa 0.2. Ƙarfin ɓarna ya kasance mai girma a zazzabi na ɗaki da mitar wutar lantarki, wanda bai shafe shi da polarity ba. Koyaya, saboda ingantacciyar asarar dielectric ɗinta, PVC bai dace da manyan ƙarfin lantarki da aikace-aikacen mitoci masu yawa ba, ana amfani da shi azaman kayan rufewa don ƙananan igiyoyi masu ƙarfi da matsakaici waɗanda ke ƙasa da 15kV.
(2) Tsawon tsufa: Yayin da tsarin kwayoyin ke nuna kyakkyawan kwanciyar hankali saboda chlorine-carbon bonds, PVC yana kula da sakin hydrogen chloride yayin aiki a ƙarƙashin zafi da damuwa na inji. Oxidation yana haifar da lalacewa ko haɗin kai, yana haifar da canza launi, haɓakawa, raguwa mai mahimmanci a cikin kayan aikin injiniya, da lalacewar aikin rufin lantarki. Sabili da haka, dole ne a ƙara masu daidaitawa masu dacewa don inganta juriya na tsufa.
(3) Thermomechanical Properties: A matsayin amorphous polymer, PVC wanzu a cikin uku na jiki jihohi a daban-daban yanayin zafi: gilashin jihar, high-na roba jihar, kuma danko mai gudana jihar. Tare da yanayin canjin gilashin (Tg) a kusa da 80 ° C da zazzabi mai gudana game da 160 ° C, PVC a cikin yanayin gilashinsa a cikin zafin jiki ba zai iya cika buƙatun aikace-aikacen waya da na USB ba. gyare-gyare ya zama dole don cimma mafi girma na elasticity a dakin da zafin jiki yayin kiyaye isasshen zafi da juriya na sanyi. Ƙarin na'urorin filastik na iya daidaita yanayin canjin gilashin yadda ya kamata.
Game daDUNIYA DAYA (OW Cable)
A matsayin babban mai samar da kayan albarkatun waya da na USB, DUNIYA DAYA (OW Cable) yana ba da ingantaccen mahaɗan PVC don rufewa da aikace-aikacen sheathing, ana amfani da su sosai a cikin igiyoyin wutar lantarki, wayoyi na gini, igiyoyin sadarwa, da na'urorin lantarki. Kayan mu na PVC yana nuna kyakkyawan rufin lantarki, jinkirin harshen wuta, da juriya na yanayi, suna bin ka'idodin kasa da kasa kamar UL, RoHS, da ISO 9001. Mun himmatu don isar da amintaccen mafita na PVC mai tsada wanda aka kera don bukatun abokan cinikinmu.
