Ipolyvinyl chloride (PVC) intlama Resin, njengoko negama lisitsho, kukuba le resin isetyenziswa ikakhulu kwifomu yokuncamathisela. Abantu bahlala besebenzisa olu hlobo lokuncamathelisa njengeplastisol, eluhlobo olulodwa lolwelo lwePVC yeplastiki kwimeko yalo engalungiswanga. . I-resins yokunamathisela idla ngokulungiswa nge-emulsion kunye neendlela zokumisa ezincinci.
I-Polyvinyl chloride paste resin inobungakanani be-particle encinci, kwaye ukuthungwa kwayo kufana ne-talc, kunye nokungahambi. I-polyvinyl chloride paste resin ixutywe kunye nePlasticizer kwaye emva koko ixutywe ukwenza ukumiswa okuzinzileyo, okuye kwenziwa kwi-PVC yokunamathisela, okanye i-PVC plastisol, i-PVC sol, kwaye ikule fomu abantu abasetyenziselwa ukucubungula iMveliso yokugqibela. Kwinkqubo yokwenza i-paste, iifayili ezahlukeneyo, i-diluents, i-stabilizers yokushisa, i-agent e-foaming kunye ne-stabilizers yokukhanya yongezwa ngokweemfuno zeemveliso ezahlukeneyo.
Ukuphuhliswa kweshishini le-PVC lokunamathisela i-resin libonelela ngodidi olutsha lwezinto ezimanzi eziba yimveliso ye-polyvinyl chloride kuphela ngokufudumeza. Olu hlobo lwemathiriyeli engamanzi kulula ukuyiqwalasela, luzinzile ekusebenzeni, kulula ukulawula, kulula ukuyisebenzisa, lugqwesileyo ekusebenzeni kwemveliso, lulungile kwimichiza yozinzo, lunamandla athile omatshini, kulula ukuwufaka umbala, njl., ngoko ke lusetyenziswa ngokubanzi. kwisikhumba sokwenziwa, iithoyi zevinyl, iimpawu zorhwebo ezithambileyo, Ukuveliswa kwephepha lodonga, iipeyinti kunye neengubo, iiplastiki ezinogwebu, njl.
Ipropati:
I-PVC yokucola i-resin (i-PVC) luhlu olukhulu lwee-resin ze-polyvinyl chloride. Xa kuthelekiswa ne-resins yokunqunyanyiswa, ngumgubo ochithwa kakhulu. Uluhlu lwesayizi ye-particle ngokuqhelekileyo yi-0.1 ~ 2.0μm (i-particle size distribution of suspension resins ngokubanzi yi-20 ~ 200μm. ). I-PVC yokunamathisela i-resin yaphandwa kumzi-mveliso we-IG Farben eJamani ngo-1931, kwaye imveliso yemizi-mveliso yafunyanwa ngo-1937.
Kwisiqingatha senkulungwane edlulileyo, imveliso yePvc Resin yokuncamathelisa yehlabathi ikhule ngokukhawuleza. Ngokukodwa kule minyaka ilishumi idlulileyo, umthamo wemveliso kunye nemveliso ibonise ukukhula okukhulayo, ngakumbi e-Asiya. Ngo-2008, umthamo wehlabathi jikelele wemveliso yokuncamathelisa i-PVC resin yayimalunga ne-3.742 yezigidi zeetoni ngonyaka, kwaye umthamo wemveliso e-Asia wawumalunga ne-918,000 yeetoni, ezibalelwa kwi-24.5% yomthamo wemveliso iyonke. I-China ngowona mmandla ukhula ngokukhawuleza kushishino lwentlaka ye-PVC yentlama, kunye nomthamo wemveliso omalunga ne-13.4% yomthamo wemveliso yehlabathi jikelele kwaye malunga ne-57.6% yomthamo wemveliso uwonke e-Asia. Ngoyena mvelisi mkhulu eAsia. Ngo-2008, imveliso yehlabathi yentlama yePVC intlama yayimalunga ne-3.09 yezigidi zeetoni, kwaye imveliso yaseTshayina yayiziitoni ezingama-380,000, ibala malunga ne-12.3% yemveliso iyonke yehlabathi. Umthamo wemveliso kunye nemveliso ikwindawo yesithathu kwihlabathi.
