pvc resin yefirimu yakaoma,
PVC resin firimu giredhi, PVC resin yefirimu, PVC resin yefirimu yakajeka,
Rigid PVC FIlms chinhu chinochinjika chekurongedza chinoshandiswa kune akasiyana kurongedza maapplication.Chigadzirwa chacho chiri nyore kushandisa sechinopesana nemamwe mapurasitiki substrates ... maitiro ayo sekujeka, kuumbwa patembiricha yakaderera, kudhinda kuri nyore kunoita kuti ive chigadzirwa chekureruka.
Kugadzira uye kushandiswa kwePVC rigid transparent film, resin inotaridzwa nekadiki kugovaniswa kwedhigirii resin polymerization kuti ive nechokwadi chekushanda kwayo kweplasticizing uye maitiro akanaka emuchina. Resin maziso ehove netsvina ishoma, zvigadzirwa "crystal points" zvishoma, transmittance yakanakisa. .
Polyvinyl chloride (PVC) resin ndeyepamusoro polima inogadzirwa ne polymerization ye ethylene.Suspension polymerization inoshandiswa seyakajairwa maindasitiri epolymerization nzira.Inowanzova yakasimba inogona kupfaviswa nekupisa.Kana ichipisa, inowanzova nehuwandu hwekushisa kwekunyunguduka kana kunyorova, uye inogona kunge iri mupurasitiki inoyerera pasi pekuita kwemasimba ekunze.Iyo fekitori inogona kuwedzera plasticizer kana mamwe anobatsira kuti asangane nezvinodiwa zvekugadzira zvinoenderana nekuita zvinodiwa zvezvigadzirwa zvepurasitiki.
Grade S-1300 inonyanya kushandiswa kugadzira yakakwirira-simba flexible zvigadzirwa, akatsikirirwa zvinhu, rigid uye flexible extrusion molding uye insulating zvinhu, etc. Zvakadai sefirimu rakatetepa, ndiro yakatetepa, yakagadzirwa nedehwe, waya, cable sheath uye nyoro marudzi ose emaprofiles.
