I-PVC Material

I-Polyvinyl chloride (okunye: i-poly(i-vinyl chloride), i-colloquial: i-polyvinyl, noma i-vinyl nje; kafushane: i-PVC) iyi-polymer yokwenziwa yepulasitiki yesithathu emhlabeni wonke (ngemuva kwe-polyethylene ne-polypropylene).Cishe amathani ayizigidi ezingama-40 ePVC akhiqizwa unyaka ngamunye.

I-PVC iza ngezinhlobo ezimbili eziyisisekelo: iqinile (ngezinye izikhathi ifushanisiwe njenge-RPVC) futhi iyavumelana nezimo.Ifomu eliqinile le-PVC lisetshenziselwa ukwakhiwa kwamapayipi nasezinhlelweni zephrofayili njengeminyango namafasitela.Ibuye isetshenziselwe ukwenza amabhodlela epulasitiki, ukupakisha okungekona ukudla, amashidi okumboza ukudla namakhadi epulasitiki (njengamakhadi asebhange noma obulungu).Ingenziwa ibe thambile futhi iguquguquke ngokwengeziwe ngokufakwa kwama-plasticizers, asetshenziswa kakhulu ama-phthalates.Kuleli fomu, liphinde lisetshenziswe ekufakeni amapayipi, ukufakwa kwezintambo zikagesi, ukulingisa isikhumba, ukubeka phansi, izimpawu, amarekhodi egilamafoni, imikhiqizo e-inflatable, kanye nezinhlelo zokusebenza eziningi lapho ithatha indawo yenjoloba.Ngokotini noma ilineni, isetshenziselwa ukukhiqizwa kwendwangu.

I-polyvinyl chloride ehlanzekile iqinile, iqinile.Ayincibiliki otshwaleni kodwa incibilika kancane ku-tetrahydrofuran.

I-PVC yahlanganiswa ngo-1872 ngusokhemisi waseJalimane u-Eugen Baumann ngemva kophenyo olunwetshiwe nokuhlola.I-polymer yabonakala iqinile emhlophe ngaphakathi kwefulaski ye-vinyl chloride eyayishiywe eshalofini elivikelwe ukukhanya kwelanga amasonto amane.Ekuqaleni kwekhulu lama-20, usokhemisi waseRussia u-Ivan Ostromislensky noFritz Klatte benkampani yamakhemikhali yaseJalimane i-Griesheim-Elektron bobabili bazama ukusebenzisa i-PVC emikhiqizweni yezentengiselwano, kodwa ubunzima bokucubungula i-polymer eqinile, ngezinye izikhathi ephukayo kwayiphazamisa imizamo yabo.U-Waldo Semon kanye ne-BF Goodrich Company bakha indlela ngo-1926 yokwenza i-PVC ibe ipulasitiki ngokuyihlanganisa nezithasiselo ezihlukahlukene, kuhlanganise nokusetshenziswa kwe-dibutyl phthalate ngo-1933.
