Malunga nale nto
INdlu ibalulekile-Ifanelekile ukusetyenziswa kwezandla kwimisebenzi yasekhaya efana nokuhlamba izitya, ukucoca, ukukhathalela abantu abadala, ukulungiswa kweentyatyambo kunye nokunye.
Ukhuseleko lwemikhono emide-uMgangatho oPhezulu kunye nemathiriyeli yePVC engangenwa ngamanzi enepateni yeentyatyambo kwindawo eyandisiweyo yengalo yezi glavu
I-Polyvinyl chloride (PVC) ngumsunguli we-vinyl chloride monomer (VCM) kwi-peroxide, iikhompawundi ze-azo, njl njl.Okanye phantsi kwesenzo sokukhanya kunye nobushushu ngokwendlela yokusabela ye-polymerization yamahhala ye-polymer.I-homopolymer ye-vinyl chloride kunye ne-copolymer zevinyl chloride zibizwa ngokuba vinyl chloride resins.
I-PVC yesakhiwo se-amorphous somgubo omhlophe, idigri ye-branched incinci, ukuxinana kwe-1.4, ubushushu beglasi ye-77 ~ 90℃, 170℃okanye ke yaqala ukubola, ukuzinza okubi kubushushu kunye nokukhanya, ngaphezu kwe-100℃okanye ilanga ixesha elide, liya kubola kwaye livelise i-hydrogen chloride, kunye nokubola okuzenzekelayo okuzenzekelayo, kubangele ukubola, iipropati zomzimba kunye noomatshini nazo zawa ngokukhawuleza,Eziqhelaniseni, izinzile kufuneka zongezwe ukuphucula ukuzinza kwe-thermal kunye nokukhanya.
Ubunzima bemolekyuli yePVC eveliswe lishishini ngokubanzi ikuluhlu lwe-50,000 ~ 110,000, kunye ne-polydispersity enkulu, kwaye ubunzima bemolekyuli buyanda ngokuncipha kobushushu bepolymerization; Akukho ndawo yokunyibilika esisigxina, 80 ~ 85℃ukuthambisa, 130℃kwimo ye-viscoelastic, 160 ~ 180℃ukutshintshela kwisimo sokuqukuqela kwe-viscous;Ineempawu ezilungileyo zoomatshini, ukomelela kwe-tensile malunga ne-60MPa, amandla empembelelo ye-5 ~ 10kJ/m2; Iimpawu ezigqwesileyo zedielectric.
I-PVC yayiyeyona mveliso inkulu yehlabathi yeeplastiki zenjongo jikelele, isetyenziswa ngokubanzi kwizinto zokwakha, iimveliso zoshishino, iimfuno zemihla ngemihla, isikhumba somgangatho, i-tile yomgangatho, isikhumba sokwenziwa, umbhobho, ucingo kunye nentambo, ifilimu yokupakisha, ibhotile. , izinto ezinogwebu, izinto zokutywina, ifayibha njalo njalo.
