Xabagta PVC ee gacanta ilaalinta korantada
Xabagta PVC ee gacanta ilaalinta korantada,
Heerka Cable ee PVC, PVC ee Xargaha Korontada, Hakinta xabagta PVC,
Tuubbada xadhkaha leh ee PVC ee ololku waxay tixraacaysaa xabagta PVC oo ah alaabta ceeriin ee ugu weyn, iyadoo lagu darayo waxyaabo kale oo lagu daro qaabaynta fiilada korantada iyo ilaalinta fiilada ee warshadaha iyo injineernimada dhismaha ee ka hooseeya 1000V.Sababtoo ah miisaankeeda fudud, ololka ololka, dahaarka wanaagsan, rakibaadda iyo isticmaalka ku habboon, caafimaadka, wasakhaysan, qiimo jaban, nolosha adeegga dheer iyo faa'iidooyinka kale, sannadihii la soo dhaafay, waxaa si ballaaran loo isticmaalay qurxinta gudaha guriga iyo dhismaha injineernimada biyaha. rakibidda ilaalinta tuubooyinka.
Daaska korantada ee adag ee POLYvinyl (PVC-U) waxay leedahay saddex nooc oo fudud, dhexdhexaad ah iyo culus, 6 tilmaamo, siday u kala horreeyaan oo ku habboon codsiyada kala duwan.Tuubada iftiinku waxay ku habboon tahay cadaadinta dhalaalaya, tuubada dhexdhexaadka ah iyo tan culus waxay qaadi kartaa cadaadiska ka sarreeya 750N iyo 1250N siday u kala horreeyaan.Sidaa darteed, waxaa lagu rakibi karaa si furan ama mugdi ah dhammaan noocyada shubka iyada oo aan dillaacin sababtoo ah cadaadis.Isla mar ahaantaana, iyada oo la tixgelinayo gaar ahaan isticmaalka badeecada, dab-demiska ayaa lagu daraa caanaha, si loo hubiyo badbaadada iyo isku hallaynta alaabta ee habka isticmaalka.Alaabta lafteedu kuma jiraan wax balaastig ah, markaa ma jirto khatar qarsoon oo soo jiidata cayayaanka iyo jiirka sababtoo ah ur gaar ah.
Waxa uu leeyahay balaastig heerkulbeeg ah, oo aan lagu milmi karin biyaha, shidaalka iyo aalkolada, bararsan ama lagu milmay ether, ketone, hydrocarbons aliphatic koloriin leh, iyo hydrocarbon caraf udgoon, caabbinta sare ee daxalka, iyo hantida dielectric wanaagsan.
