Ngaphambi kokuba i-PVC inokwenziwa kwiimveliso, kufuneka idityaniswe noluhlu lweesongezo ezikhethekileyo. Ezi zongezo zinokuba nefuthe okanye zichonge inani leepropathi, ezizezi; Iipropathi zayo zoomatshini, ukutya kwemozulu yemozulu, umbala wayo kunye nokucaca kwaye ngokwenene nokuba isetyenziswe kwisicelo esiguqukayo. Le nkqubo ibizwa ngokuba yingqungquthela. Ukuhambelana kukaPVC kunye neentlobo ezininzi zezongezo yenye yezinto amandla amaninzi kwaye yintoni ebangela ukuba i-polymer ye-polymer. I-PVC inokubekwa iplastikitywe ukuba iguqulwe ukuze isetyenziswe kumgangatho kunye neemveliso zonyango. I-rigid pvc, ekwabizwa ngokuba yi-PVC-U (i-U (i-U imele "ukungasebenzi") isetyenziswa kakhulu kwizicelo zokwakha ezifana nezakhelo zefestile.

Izongezo ezisebenzayo ezisetyenzisiweyo kuzo zonke izinto ze-PVC zibandakanya ukuziswa kwe-ft, ioyile, nakwimeko ye-PVC eguquguqukayo, iplastiki. Izicelo zoongezelelo ezinokukhetheka, zibandakanya uluhlu lwezinto ezikhoyo ezivela kwi-AIDS, iimodyuli zempembelelo, iziko le-Irmal, i-UV STABISISE, IIPROOTERS, IINDAWO ZOKUZIPHATHA, NE-ARDS STOCES, NAMABHUNGA OLUFANELEKILEYO, NE-ARDS yokuvuthuza kwizicelo ezithile. Eyona nto iphambili ye-PVC ye-PVC kwezinye izicelo zomgangatho zinokuba sezantsi njenge-25% ngobunzima, intsalela ibalwe i-songer. Ukuhambelana kwazo ezongeziweyo kuvumela ukongezwa okunokwenzeka kwe-reloarys nangona i-pvc ibuyiselwe ngomlilo ngenxa yobukho be-chlorine matrix.

Imisebenzi esebenzayo

I-SUFFAZES

Izinzi zobushushu ziyimfuneko kuzo zonke iifomu ze-PVC ukuthintela ukubola kwe-PVC ngobushushu kunye nokucheba ngexesha lokuqhutywa. Banokuphucula ukumelana nokuxhathisa i-PVC kwimini, nakwimozulu kunye nesalupela. Ukongeza abenzi bobushushu banefuthe elibalulekileyo kwiipropathi zomzimba ze-PVC kunye neendleko zokwenza oko. Ukukhetha i-stabilizer yobushushu kuxhomekeke kwinani lezinto kubandakanya iimfuno zobugcisa zemveliso ye-PVC, iimfuno zokuvunywa kolawulo kunye neendleko.

I-LubiricsEzi zisetyenziselwa ukunciphisa ukungqubana ngexesha lokuqhutywa. I-leoneries yangaphandle inokunciphisa ukungqubana phakathi kwe-PVC kunye nezixhobo zokulungisa, ngelixa i-boodwants yangaphakathi isebenza kwi-PVC Granules.

IiplasitikiIplastikisi sisixhobo esibonakalayo xa sisongezwa kwimpahla, ihlala iplastiki, isenza ukuba ibe bhetyebhetye, isebenze kwaye ibe lula ukuphatha. Imizekelo yakuqala yabasebenzisi bephangiyer ibandakanya amanzi kwidongwe kunye ne-oyile ukuya kwi-plastike yeplastike yokufaka amanzi. Ukukhethwa kweeplastiki kuxhomekeke kwipropathi yokugqibela efunwa yimveliso yokugqibela, kwaye ngokwenene iMveliso yeyokusetyenziswa komgangatho okanye isicelo sezonyango. Zingaphezulu kwe-300 iintlobo ezahlukeneyo zeplastiki ezimalunga ne-50-100 ekusebenziseni ukuthengisa. Olona nyango luqhelekileyo lusetyenziswayo ziiPthalates ezinokwahlulahlulwa zangamaqela amabini ahlukeneyo kunye nezicelo ezahlukeneyo kakhulu kunye nokuhlelwa; I-Phthalates ephantsi: Ubunzima obuphantsi kwemolekyuli (i-LMW) phthalates iqulethe ii-atom ezisibhozo okanye ezincinci kwi-carbon kwi-backbone yazo. Oku kubandakanya, i-Dehp, i-DBP, i-Dibp kunye ne-BBP. Ukusetyenziswa kwezi Phthalates eYurophu kunqamlezwe kwizicelo ezithile ezikhethekileyo. IPhthalates ephezulu: Ubunzima obuphezulu (i-HMW) Phthalates ngabo banee-atom zecarbon kwi-backbone yabo yekhemikhali. Oku kubandakanya: InDP, i-DOPP, i-DPHP, iDip kunye ne-DTDP. I-HMW Phthalates isetyenziswa ngokukhuselekileyo kwimihla emininzi kubandakanya iintambo kunye nomgangatho. Iiplasitikidi ezikhethekileyo, ezinjengokuziqeqesha, iiriteri, i-BenzoCates kunye nezona zisetyenziswayo apho kufuneka khona amaqondo obushushu aphantsi okanye apho bhetyebhetye kakhulu. Uninzi lweemveliso ze-PVC esiyisebenzisayo yonke imihla kodwa zidla ngokuthatha i-phthale chestshears. Babandakanya yonke into evela kwizixhobo zonyango ezisindisisayo ezifana ne-tubing yezonyango kunye neengxowa zegazi, kwiintambo zombane, ukupakisha, izinto zokubhala, neethoyi. Ukongeza, i-Phthalates isetyenziswa kwezinye izicelo ezingezizo ze-PVC ezinjengeepeyinti, iimveliso zerabha, amachaphaza kunye ne-cosmetics.

Izongezo ezinokukhethwa

Ezi zongezelelo zokhetho azinyanzelekanga ngokungqongqo kwingqibelelo yeplastiki kodwa zisetyenziselwa ukuzoba-phezu kwezinye iipropathi. Izongezo ezinokukhetheka zibandakanya izixhobo zokulungisa, iindlela zempembelelo, iifilimu, iirubrile zeribeki, imibala kunye neencwadi ezinqabileyo kunye neflayasi.
