I-PVC ku-Wire kanye ne-Cable: Izakhiwo Zezinto Ezibalulekile

1. I-PVC Resin

I-resin ye-PVC iyi-polymer eqondile ye-thermoplastic eyakhiwe yi-polymerization yama-monomers e-vinyl chloride. Isakhiwo sayo sama-molecule sinezici ezilandelayo:

(1) Njenge-polymer ye-thermoplastic, ikhombisa ukuguquguquka okuhle kanye nokuguquguquka.

(2) Ukuba khona kwezibopho ze-polar ze-C-Cl kunikeza i-resin i-polarity enamandla, okuholela ku-dielectric constant ephezulu (ε) kanye ne-dissipation factor (tanδ), kuyilapho kunikeza amandla aphezulu e-dielectric kuma-frequency aphansi. Lezi zibopho ze-polar nazo zinegalelo emandleni aqinile aphakathi kwama-molecule kanye namandla aphezulu omshini.

(3) Ama-athomu e-chlorine esakhiweni sama-molecule anikeza izakhiwo ezivimbela ilangabi kanye nokumelana okuhle kwamakhemikhali nesimo sezulu. Kodwa-ke, lawa ma-athomu e-chlorine aphazamisa isakhiwo sekristalu, okuholela ekumelaneni nokushisa okuphansi kanye nokumelana nokubanda okubi, okungathuthukiswa ngezithasiselo ezifanele.

2. Izinhlobo ze-PVC Resin

Izindlela zokwenza i-polymerization ye-PVC zifaka: i-suspension polymerization, i-emulsion polymerization, i-bulk polymerization, kanye ne-solution polymerization.

Indlela yokwenza i-polymerization yokumiswa njengamanje ibaluleke kakhulu ekukhiqizweni kwe-resin ye-PVC, futhi lolu uhlobo olusetshenziswa ekusetshenzisweni kwezintambo nezintambo.

Ama-resin e-PVC axutshwe ne-suspension ahlukaniswa ngezinhlobo ezimbili zesakhiwo:
I-resin yohlobo olukhululekile (uhlobo lwe-XS): Ibonakala ngesakhiwo esinezimbobo, ukumuncwa kwe-plasticizer ephezulu, ukuqiniswa okulula, ukulawula ukucubungula okulula, kanye nezinhlayiya ezimbalwa zejeli, okwenza kube ukukhetha okuthandwayo kokusetshenziswa kwezintambo nekhebula.
I-resin yohlobo oluhlangene (uhlobo lwe-XJ): Isetshenziswa kakhulu kweminye imikhiqizo yepulasitiki.

3. Izakhiwo Eziyinhloko ze-PVC

(1) Izakhiwo Zokufaka Ugesi: Njengezinto ezisebenza nge-dielectric ezisezingeni eliphezulu, i-resin ye-PVC ikhombisa izakhiwo ezinhle kodwa eziphansi kancane zokufaka ugesi uma kuqhathaniswa nezinto ezingezona ezisezingeni eliphezulu njenge-polyethylene (PE) kanye ne-polypropylene (PP). Ukumelana kwevolumu kudlula i-10¹⁵ Ω·cm; ku-25°C kanye ne-50Hz frequency, i-dielectric constant (ε) isukela ku-3.4 kuya ku-3.6, ihlukahluka kakhulu ngokushintsha kwezinga lokushisa kanye nemvamisa; i-dissipation factor (tanδ) isukela ku-0.006 kuya ku-0.2. Amandla okuqhekeka ahlala ephezulu ekushiseni kwegumbi kanye nemvamisa yamandla, engathinteki yi-polarity. Kodwa-ke, ngenxa yokulahleka kwayo okuphezulu kwe-dielectric, i-PVC ayifanele ukusetshenziswa kwe-high-voltage kanye nemvamisa ephezulu, njengoba ivame ukusetshenziswa njengezinto zokufaka ugesi zezintambo ezisezingeni eliphansi neliphakathi ezingaphansi kuka-15kV.

(2) Ukuzinza Kokuguga: Ngenkathi isakhiwo sama-molecule sibonisa ukuzinza okuhle kokuguga ngenxa yezibopho ze-chlorine-carbon, i-PVC ivame ukukhulula i-hydrogen chloride ngesikhathi sokucubungula ngaphansi kokucindezeleka kokushisa nokwemishini. Ukubola kuholela ekuwohlokeni noma ekuxhumeni, okubangela ukushintsha kombala, ukuqhekeka, ukwehla okukhulu kwezakhiwo zemishini, kanye nokuwohloka kokusebenza kokufakwa kukagesi. Ngakho-ke, iziqinisi ezifanele kumele zengezwe ukuze kuthuthukiswe ukumelana nokuguga.

(3) Izakhiwo ze-Thermomechanical: Njenge-polymer engaguquki, i-PVC ikhona ezimweni ezintathu ezibonakalayo emazingeni okushisa ahlukene: isimo sengilazi, isimo se-high-elastic, kanye nesimo sokugeleza okuqinile. Njengoba izinga lokushisa lokushintsha kwengilazi (Tg) licishe libe ngu-80°C kanye nezinga lokushisa lokugeleza licishe libe ngu-160°C, i-PVC esimweni sayo sengilazi emazingeni okushisa egumbi ayikwazi ukuhlangabezana nezidingo zokusetshenziswa kwentambo nekhebula. Ukuguqulwa kuyadingeka ukuze kufezwe ukuqina okuphezulu emazingeni okushisa egumbi ngenkathi kugcinwa ukushisa okwanele kanye nokumelana nokubanda. Ukwengezwa kwama-plasticizer kungalungisa ngempumelelo izinga lokushisa lokushintsha kwengilazi.

MayelanaIZWE ELILODWA (Ikhebula le-OW)

Njengomhlinzeki ohamba phambili wezinto zokusetshenziswa zocingo nezintambo, i-ONE WORLD (OW Cable) inikeza ama-PVC asezingeni eliphezulu okusetshenziswa kokuvikela nokuvikela, asetshenziswa kabanzi ezintanjeni zikagesi, ezintanjeni zokwakha, ezintanjeni zokuxhumana, kanye nasezintanjeni zezimoto. Izinto zethu ze-PVC zinokuvikela okuhle kakhulu kukagesi, ukubambezeleka komlilo, kanye nokumelana nesimo sezulu, okuhambisana nezindinganiso zomhlaba wonke ezifana ne-UL, RoHS, kanye ne-ISO 9001. Sizibophezele ekuletheni izixazululo ze-PVC ezithembekile nezingabizi kakhulu ezilungiselelwe izidingo zamakhasimende ethu.
