Umahluko phakathi kwePP kunye nePVC kungakhathaliseki ukuba imbonakalo okanye imvakalelo inokwahluka kakhulu; Ukuziva kwePP kunzima kwaye iPVC ithambile.
I-PP i-resin ye-thermoplastic elungiselelwe yi-polymerization yepropylene. Kukho ukucwangciswa okuthathu kweemveliso ze-isochronous, ezingalawulwayo kunye ne-interchronous, kunye neemveliso ze-isochronous zizona zixhobo eziphambili zeemveliso zoshishino. I-Polypropylene iquka i-copolymers yepropylene kunye nenani elincinci le-ethylene. Ngokwesiqhelo translucent eqinileyo, engenavumba, ayinabungozi.
Iimpawu: i-non-toxic, i-tasteless, ubuninzi obuphantsi, amandla, ukuqina, ukuqina kunye nokumelana nokushisa kungcono kunoxinzelelo oluphantsi lwe-polyethylene, ingasetyenziselwa kwii-degrees eziyi-100 okanye kunjalo. Iipropathi ezilungileyo zombane kunye nokugqunyelelwa kwamaza ombane aphezulu azichatshazelwa kukufuma, kodwa zibe brittle kubushushu obuphantsi, zinganxibi, ziguge lula. Ifanelekile ukwenza iindawo zoomatshini ngokubanzi, iindawo ezinganyangekiyo kumhlwa kunye neendawo zokugquma.
I-PVC yenye yeemveliso zeplastiki ezinkulu zehlabathi, ezitshiphu, ezisetyenziswa ngokubanzi, i-polyvinyl chloride resin imhlophe okanye ilula emthubi. Izongezo ezahlukeneyo zingongezwa ngokwe-USES ezahlukeneyo, kwaye iiplastiki ze-polyvinyl chloride zineempawu ezahlukeneyo zomzimba kunye noomatshini. Ukongeza i-plasticizer efanelekileyo kwi-polychlorethylene resin inokwenziwa kwiintlobo ezahlukeneyo zeemveliso ezinzima, ezithambileyo kunye nezicacileyo. Ubuninzi be-PCC ecocekileyo yi-1.4g / cm3, kwaye ubuninzi beeplasticizers ze-PCC kunye nokuzaliswa ngokubanzi yi-1.15-2.00g / cm3. I-POLYchlorethylene enzima ine-tensile elungileyo, i-flexural, i-compressive kunye nempembelelo yokuchasana kwaye inokusetyenziswa njengezinto zokwakha zodwa.
