Umugqa wokuvala we-EPDM iyinto evamile yokuvala eyenziwe nge-ethylene-propylene-diene copolymer (EPDM).Inezinzuzo eziningi, nazi ezinye zazo:
1. Ukumelana nesimo sezulu:Ingakhombisa ukumelana nesimo sezulu esihle ngaphansi kwezimo zezulu ezahlukahlukene.Ingakwazi ukumelana nokushintsha kwezinga lokushisa okwedlulele, imisebe ye-UV kanye nokungcoliswa komoya ngaphandle kokulahlekelwa ukusebenza kwayo kwasekuqaleni.
2. Ukumelana namakhemikhali: Ukumelana namakhemikhali aphezulu kuma-acids, ama-alkali, ama-solvents namanye amakhemikhali.Ingakwazi ukumelana nokuguguleka kwezinto ezonakalisayo futhi yandise impilo yesistimu yokuvala uphawu.
3. Ukunwebeka okuphezulu nokululama: Inokuqina okuhle nokusebenza kokululama.Ingabuyela ngokushesha esimweni sayo sasekuqaleni ngemva kokucindezelwa noma ukwelula, iqinisekisa ukusebenza kophawu futhi ivimbele ukuvuza koketshezi noma igesi.
4. Izakhiwo ezinhle kakhulu zemishini: amandla aphezulu okudonsa kanye nokumelana nezinyembezi.Ingakwazi ukumelana nokucindezeleka komshini okufana nokukhipha, ukudonsa nokusonteka, ukugcina ubuqotho bayo nokusebenza kokuvala.
5. Ukumelana nokushisa: Inokumelana nokushisa okuphezulu.Ingasebenza ezindaweni zokushisa okuphezulu, ukumelana nokuguga okushisayo kanye nokuguqulwa kokushisa, futhi iqinisekise ukwethembeka kwesistimu yokubeka uphawu.
6. Ukufakwa komsindo nomphumela wokumunca ukushaqeka: Ine-insulation enhle yomsindo kanye nomphumela wokumunca ukushaqeka.Ingavimba ngempumelelo ukudluliswa komsindo, ukudlidliza nokushaqeka, inikeze indawo enethezekile nethule.
7. Izakhiwo ezinhle zokuvikela ugesi: Inezindawo ezinhle zokuvala ugesi futhi ingavimbela ukuhamba kwamandla futhi igweme izifunda ezimfushane kanye nokwehluleka kwemishini kagesi noma izintambo.
8. Ivumelana nemvelo futhi iyasimeme: Umugqa wokuvala we-EPDMiyimpahla evumelana nemvelo futhi eqhubekayo.Ayiqukethe izinto eziyingozi, ayinabo ubuthi futhi ayinaphunga, futhi ayinabungozi emzimbeni womuntu nasendaweni ezungezile.Ngesikhathi esifanayo, ikwazi ukuphinda isetshenziswe kabusha kakhulu, okunganciphisa ukukhiqizwa kokulahlwa kanye nokuchithwa kwezinsiza.
Ngamafuphi,Imichilo yokuvalwa kwe-EPDMzinezinzuzo zokumelana nesimo sezulu, ukumelana namakhemikhali, ukunwebeka okuphezulu, izakhiwo ezinhle kakhulu zemishini, ukumelana nokushisa, ukuvaleka komsindo kanye nemiphumela yokumunca ukushaqeka, izakhiwo ezinhle zokuvala ugesi, nokusimama kwemvelo.Lezi zici zenza ama-sealant strips asetshenziswe kabanzi ekwakhiweni, izimoto, i-electronics, i-aerospace kanye neminye imikhakha, ehlinzeka ngezixazululo ezinokwethenjelwa zezidingo ezihlukahlukene zokuvala.
