Mayelana nale nto
Ibalulekile Yasekhaya - Ilungele ukusetshenziswa ngezandla emisebenzini yasendlini njengokugeza izitsha, ukuhlanza, ukunakekela abantu abadala, ukuhlela izimbali nokunye.
Ukuvikelwa Kwemikhono Emide - Ikhwalithi ephezulu kanye nempahla ye-PVC engenamanzi enephethini yezimbali endaweni yengalo enwetshiwe yalawa magilavu
I-Polyvinyl chloride (PVC) ingumsunguli we-vinyl chloride monomer (VCM) ku-peroxide, i-azo compounds, njll.Noma ngaphansi kwesenzo sokukhanya nokushisa ngokusho kwendlela yokusabela ye-polymerization yamahhala ye-polymer.I-homopolymer ye-vinyl chloride ne-copolymer i-vinyl chloride ibizwa ngokuthi i-vinyl chloride resins.
I-PVC yesakhiwo se-amorphous se-powder emhlophe, i-branched degree incane, ukuminyana kwesihlobo 1.4, izinga lokushisa lokuguqulwa kwengilazi lika-77 ~ 90℃, 170℃noma ngakho-ke yaqala ukubola, ukuzinza okubi ekushiseni nasekukhanyeni, ngaphezu kwe-100℃noma ilanga isikhathi eside, lizobola futhi likhiqize i-hydrogen chloride, futhi okunye ukubola okuzenzakalelayo kwe-catalytic, kubangele ukushintsha kombala, izakhiwo ezingokomzimba nezomshini nazo zawa ngokushesha,Ngokomkhuba, iziqinisi kufanele zengezwe ukuze kuthuthukiswe ukuzinza okushisayo nokukhanya.
Isisindo samangqamuzana e-PVC akhiqizwa imboni ngokuvamile sisukela ku-50,000 ~ 110,000, ane-polydispersity enkulu, futhi isisindo samangqamuzana siyanda ngokuncipha kwezinga lokushisa le-polymerization;Alikho iphuzu elincibilikayo elingaguquki, 80~85℃ukuthambisa, 130℃kusimo se-viscoelastic, i-160 ~ 180℃ukushintshela esimweni sokugeleza kwe-viscous;Inezici ezinhle zokusebenza, amandla aqinile acishe abe ngu-60MPa, amandla omthelela angu-5~10kJ/m2;Izici ze-dielectric ezinhle kakhulu.
I-PVC yayiwumkhiqizo omkhulu kunawo wonke emhlabeni wamapulastiki anenhloso ejwayelekile, asetshenziswa kabanzi.Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, ithayela laphansi, isikhumba sokwenziwa, ipayipi, intambo nekhebula, ifilimu yokupakisha, ibhodlela. , izinto ezikhihliza amagwebu, izinto zokuvala, ifayibha nokunye.
