Umtya wokutywina we-EPDM yinto eqhelekileyo yokutywina eyenziwe nge-ethylene-propylene-diene copolymer (EPDM). Ineenzuzo ezininzi, nazi ezinye zazo:
1. Ukumelana nemozulu:Ingabonisa ukumelana nemozulu elungileyo phantsi kweemeko ezahlukeneyo zemozulu. Inokumelana nokutshintsha kobushushu obugqithisileyo, imitha ye-UV kunye nongcoliseko lomoya ngaphandle kokulahlekelwa ngumsebenzi wayo wokuqala.
2. Ukumelana nemichiza: Ukumelana neekhemikhali eziphezulu kwi-acids, alkalis, solvents kunye nezinye iikhemikhali. Iyakwazi ukumelana nokukhukuliseka kwezinto ezonakalisayo kwaye yandise ubomi benkqubo yokutywina.
3. I-elasticity ephezulu kunye nokubuyisela: Ine-elasticity elungileyo kunye nokusebenza kokubuyisela. Inokubuyela ngokukhawuleza kwimo yayo yangaphambili emva kokunyanzeliswa okanye ukunweba, iqinisekisa ukusebenza kwesitywina kunye nokuthintela ukuvuza kolwelo okanye igesi.
4. Iimpawu ezigqwesileyo zoomatshini: amandla aphezulu kunye nokumelana nokukrazula. Inokumelana noxinzelelo lomatshini olunjengokukhupha, ukutsala kunye nokujija, ukugcina ingqibelelo kunye nokusebenza kokutywinwa.
5. Ukumelana nobushushu: Inokumelana nobushushu obuphezulu. Iyakwazi ukusebenza kwiindawo eziphezulu zokushisa, ukumelana nokuguga kwe-thermal kunye ne-thermal deformation, kunye nokuqinisekisa ukuthembeka kwenkqubo yokutywinwa.
6. Ukugquma isandi kunye nefuthe lokufunxa ukothuka: Ine-insulation elungileyo yesandi kunye nefuthe lokufunxa ukothuka. Inokuthi ithintele ngokufanelekileyo ukuhanjiswa kwesandi, ukungcangcazela kunye nokothuka, ukubonelela indawo ekhululekile kwaye ezolileyo.
7. Iimpawu ezilungileyo zokugquma umbane: Ineempawu ezilungileyo zokugquma umbane kwaye inokuthintela ukuhamba kwangoku kwaye ugweme iisekethe ezimfutshane kunye nokungaphumeleli kwezixhobo zombane okanye iingcingo.
8. Ubuhlobo bendalo kunye nozinzo: Umtya wokutywina we-EPDMsisixhobo esihambelana nokusingqongileyo kwaye silondolozeka. Ayinazinto ezinobungozi, ayinayo ityhefu kwaye ayinavumba, kwaye ayinabungozi kumzimba womntu kunye nokusingqongileyo. Kwangaxeshanye, inokuphinda isetyenziswe, nto leyo enokunciphisa ukuveliswa kwenkunkuma kunye nenkcitho yemithombo.
Ukushwankathela,Imicu yokutywina ye-EPDMzineengenelo zokuxhathisa imozulu, ukumelana neekhemikhali, ukuqina okuphezulu, iipropathi ezigqwesileyo zoomatshini, ukumelana nobushushu, ukugqunywa kwesandi kunye neziphumo zokufunxa ukothuka, iipropathi ezilungileyo zokugquma umbane, kunye nokuzinza kwendalo. Ezi mpawu zenza imicu ye-sealant isetyenziswe ngokubanzi kulwakhiwo, iimoto, i-electronics, i-aerospace kunye nezinye iindawo, ezibonelela ngezisombululo ezithembekileyo kwiimfuno ezahlukeneyo zokutywinwa.
