umehluko phakathi kwe-PP ne-PVC kungakhathaliseki ukuthi ubukeka kanjani noma uzizwa uhluke kakhulu;I-PP izwakala iqinile futhi i-PVC ithambile.
I-PP iyinhlaka ye-thermoplastic elungiselelwe i-polymerization ye-propylene.Kukhona ukucushwa okuthathu kwemikhiqizo ye-isochronous, engalawulwa kanye ne-interchronous, futhi imikhiqizo ye-isochronous iyingxenye eyinhloko yemikhiqizo yezimboni.I-Polypropylene ihlanganisa nama-copolymers e-propylene kanye nenani elincane le-ethylene.Ngokuvamile i-translucent engenambala eqinile, engenaphunga engenabuthi.
Izici: okungezona ubuthi, okunganambitheki, ukuminyana okuphansi, amandla, ukuqina, ukuqina nokumelana nokushisa kungcono kune-polyethylene yokucindezela okuphansi, ingasetshenziswa kuma-degree angu-100 noma ngaphezulu.Izakhiwo zikagesi ezinhle kanye nokufakwa kwemvamisa ephezulu akuthintwa umswakama, kodwa ziba brittle ekushiseni okuphansi, azikwazi ukumelana nokugqoka, ukuguga kalula.Ifanele ukwenza izingxenye ezijwayelekile zemishini, izingxenye ezimelana nokugqwala kanye nezingxenye zokufakelwa.
I-PVC ingenye yemikhiqizo yepulasitiki emikhulu kakhulu emhlabeni, eshibhile, esetshenziswa kabanzi, i-polyvinyl chloride resin iyimpushana ephuzi emhlophe noma ekhanyayo.Izithasiselo ezihlukene zingangezwa ngokuya nge-USES ehlukene, futhi amapulasitiki e-polyvinyl chloride anezakhiwo ezihlukile zomzimba nezomshini.Ukwengeza i-plasticizer efanele ku-polychlorethylene resin ingenziwa ibe yimikhiqizo ehlukahlukene eqinile, ethambile futhi esobala.Ukuminyana kwe-PCC emsulwa ngu-1.4g/cm3, kanti ukuminyana kwe-PCC plasticizers kanye nezigcwalisi ngokuvamile ku-1.15-2.00g/cm3.I-POLYchlorethylene eqinile inokuqina okuhle, eguquguqukayo, ecindezelayo kanye nokumelana nomthelela futhi ingasetshenziswa njengezinto zokwakha zodwa.
