PVC resin yefirimu
PVC resin yefirimu,
PVC resin yefirimu yakaoma, pvc resin for soft PVC film,
Kugadzirwa kwePVC firimu
Pane kunyanya nzira mbiri dzekugadzira pvc firimu: extrusion calendering uye casting.Extrusion calendering ndiyo nzira yakawanda.
PVC firimu rinogona kuiswa mumapoka maviri makuru: akapfava uye semi-akaoma.Kudiwa kwemusika kwehafu-yakasimba PVC firimu inosvika zvingangoita zviviri muzvitatu.
Pepa rakapfava rePVC rinowanzo shandiswa machira etafura, matinji asina kutsvedza, uye mabhegi.Nekuti rakapfava PVC sheet kana firimu rine zvinyoro-nyoro, zviri nyore kuita brittle uye zvakaoma kuchengeta.Izvi zvinoganhura nzvimbo yayo yekushandisa.
Rigid PVC haina zvinyoro-nyoro.Inochinjika, iri nyore kuumba, haisi nyore kuve brittle, isina chepfu uye isina kusvibiswa.Iine nguva yakareba yekuchengetedza, kupisa kwekushisa kwepamusoro, kwete nyore kunyunguduka.Inodhinda, uye ine inking yakanaka.Iyo yakakosha uye yakakura maapplication.Kuvaka uye zvemagetsi zvinoshandisa 60% yePVC mapurasitiki firimu uye mapepa.Maindasitiri mazhinji ekurongedza anoshandisawo yakawanda PVC zvinhu.Kune zvakare akati wandei maapplication, senge kupeta bhokisi stationery, laser yekucheka, uye partition mabhodhi uye zvichingodaro.
