Iiplastiki zezinto ezahlukeneyo zineendawo ezahlukeneyo zokunyibilika:
I-Polypropylene: Iqondo lokunyibilika liyi-165 ° C-170 ° C, ukuzinza kwe-thermal kulungile, iqondo lokushisa lokubola lingafikelela ngaphezu kwe-300 ° C, kwaye liqala ukujika lityheli kwaye liwohloke kwi-260 ° C kwimeko yokudibana ne-oxygen. , kwaye ine-anisotropy ngexesha lokubumba lobushushu obuphantsi.Kulula ukujijwa okanye ukujijwa ngenxa yokuqhelaniswa nemolekyuli, kwaye inokusebenza kakuhle kokusonga.Amasuntswana e-resin ane-waxy texture.Umyinge wokufunxa amanzi ungaphantsi kwe-0.02%.Umswakama ovumelekileyo wokubumba yi-0.05%.Ngoko ke, ukomisa ngokuqhelekileyo akwenziwanga ngexesha lokubumba.Inokomiswa malunga ne-80 ° C kwiiyure ze-1-2, kwaye iimpawu zayo zokuhamba zivakalelwa kwiqondo lokushisa kunye nesantya sokucheba ngexesha lokubumba.
I-Polyoxymethylene: Yiplastiki ekwaziyo ukumelana nobushushu enendawo yokunyibilika eyi-165°C, eya kubola ngokunzulu kwaye ijike ibe tyheli kubushushu obungama-240°C.Ixesha lokuhlala kwiqondo lokushisa lama-210 ° C akufanele lidlule imizuzu engama-20.Kuluhlu oluqhelekileyo lokufudumeza, luya kubola ukuba lufudumala ixesha elide., Emva kokubola, kuya kubakho iphunga elimnandi kunye nokukrazula.Imveliso ihamba kunye nemigca ephuzi-brown.Ubuninzi be-POM yi-1.41-1.425.-5 iiyure.
I-Polycarbonate: iqala ukuthamba ku-215°C, iqala ukuhamba ngaphezu kwe-225°C, i-viscosity enyibilikayo engaphantsi kwe-260°C iphezulu kakhulu, kwaye imveliso ithanda ukungoneli.Ubushushu bokubumba ngokuqhelekileyo buphakathi kwama-270°C kunye nama-320°C.Ukuba iqondo lokushisa lidlula i-340 ° C, ukubola kuya kwenzeka, kunye neqondo lokumisa Ubushushu buphakathi kwe-120℃-130℃, kwaye ixesha lokumisa lingaphezu kweeyure ezi-4.I-polycarbonate resin ngokuqhelekileyo ayinambala kunye namasuntswana abonakalayo.
