Iyini i-PVC Resin?

I-Polyvinyl chloride (PVC) iyi-polymer eyenziwe nge-vinyl chloride monomer (VCM) ku-peroxide, i-azo compound nezinye iziqalisi noma ngokuya ngomshini we-polymerization wamahhala ngaphansi kwesenzo sokukhanya nokushisa.I-vinyl chloride homopolymer kanye ne-vinyl chloride copolymer zihlangene zibizwa ngokuthi i-vinyl chloride resin.

I-PVC yake yaba yipulasitiki enkulu kunazo zonke emhlabeni, eyayisetshenziswa kabanzi.Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, amathayili aphansi, isikhumba sokwenziwa, amapayipi, izintambo nezintambo, ifilimu yokupakisha, amabhodlela, izinto ezigwebu, izinto zokuvala, imicu nokunye.

Ngokusho kobubanzi besicelo esihlukile, i-PVC ingahlukaniswa ibe: i-PVC resin yenhloso evamile, izinga eliphezulu le-polymerization ye-PVC resin kanye ne-PVC exhunywe ngokuphambana.Inhloso ejwayelekile ye-PVC resin yenziwa nge-polymerization ye-vinyl chloride monomer ngaphansi kwesenzo se-initiator;I-polymerization degree ephezulu ye-PVC resin ibhekisela ku-resin eyenziwe nge-polymerized ngokungeza i-ejenti yokukhula kweketanga ku-vinyl chloride monomer polymerization system;I-Crosslinked PVC resin iyi-resin eyenziwe nge-polymerized ngokungeza i-crosslinking agent equkethe i-diene ne-polyene ohlelweni lwe-vinyl chloride monomer polymerization.
Ngokwendlela yokuthola i-vinyl chloride monomer, ingahlukaniswa ngendlela ye-calcium carbide, indlela ye-ethylene kanye nokungeniswa kwamanye amazwe (EDC, VCM) indlela ye-monomer (ngokwesiko, indlela ye-ethylene kanye nendlela ye-monomer engenisiwe ibizwa ngokuhlanganyela ngokuthi indlela ye-ethylene).
