Kutheni ukhetha uphahla lwe-EPDM?

Xa ukhetha izinto zokuphahla, i-EPDM (i-ethylene propylene diene monomer) yinto ekhethekileyo kakhulu. Uphahla lwe-EPDMzibonelela ngoluhlu lweenzuzo ezenza zibe lukhetho oludumileyo lwezakhiwo zokuhlala kunye nezorhwebo.

Okokuqala kwaye ngaphambi kwento yonke,Uphahla lwe-EPDMzaziwa ngokomelela kwazo.Zenziwe kwikhompawundi yerabha eyenziweyo enika ukuchasana kwemozulu okugqwesileyo kwaye inokumelana nokutshintsha kobushushu obugqithisileyo.Nokuba bubushushu obushushu, ingqele eqhaqhazelisa amazinyo okanye imvula enkulu, uphahla lweEPDM lubonelela ngokhuseleko oluthembekileyo unyaka wonke.Ukuchasana kwabo kwimitha ye-UV kuqinisekisa ukuba uphahla aluyi kuthotywa okanye luqhekeke ngokuhamba kwexesha, okwenza kube yimali yobulumko.

Okwesibini,Uphahla lwe-EPDMzibhetyebhetye kakhulu.Inokwandisa kwaye inkontileka ngaphandle kokuphulukana neempawu zayo zendalo, iyenza ilungele izakhiwo ezihlala zishukuma okanye zihlale.Oku kuguquguquka kunciphisa kakhulu umngcipheko wokuvuza kunye nokuqhekeka, ukuqinisekisa ukuba isakhiwo sikhuselekile kumonakalo wamanzi.Ukongezelela, ukuguquguquka kwayo kwenza kube lula ukuyifaka kwiiphahla ezinemilo ekhethekileyo kunye neengile. Uphahla lwe-EPDMikwasisisombululo esineendleko ezifanelekileyo.Iindleko zayo eziphantsi zokufakela kunye nokugcinwa kwayo zenza ukuba ibe yinto ekhangayo kumntu oqaphela uhlahlo lwabiwo-mali okanye ishishini.Iimbumba ze-EPDM zilula kwaye zilula ukuphatha, ukunciphisa ixesha lofakelo kunye neendleko zabasebenzi.Ukongezelela, zifuna ukulungiswa okuncinci, ukunciphisa iindleko zokugcinwa kwexesha elide.Ukuba igcinwe ngokufanelekileyo, uphahla lwe-EPDM lunokuhlala iminyaka engama-40 kwaye luxabisa kakhulu imali.Ukongeza, uphahla lwe-EPDM lunobuhlobo kakhulu nokusingqongileyo.Zihlala zenziwe ngezinto ezisetyenzisiweyo kwaye zinokuphinda zisetyenziswe ekupheleni kobomi bazo obuluncedo.I-EPDM iphinda isebenzise amandla njengoko izinto zinceda ukulawula ubushushu kunye nokunciphisa ukusetyenziswa kwamandla okufudumeza kunye nokupholisa, ngaloo ndlela kuthoba amatyala asetyenziswayo.

Ekugqibeleni, uphahla lwe-EPDM lunikeza ukuguquguquka kwizicelo.Ziyakwazi ukufakwa ngokungenamthungo kuphahla olusicaba okanye olusezantsi kwaye lufanelekile kwizakhiwo ezahlukeneyo, kubandakanywa amakhaya, izakhiwo zorhwebo kunye nezixhobo zoshishino.Iimbumba ze-EPDM zinokudityaniswa nge-thermal okanye ziboshwe, zibonelela ngeendlela ezahlukeneyo zokufakela ngokuxhomekeke kwiimfuno ezithile zeprojekthi.Isishwankathelo, ukuphahla kwe-EPDM yinto ehlala ixesha elide, eguquguqukayo, engabizi kakhulu, ehambelana nokusingqongileyo, kunye nenketho eguquguqukayo.Ingaba ikhaya lakho okanye ishishini lifuna uphahla olutsha, uphahla lwe-EPDM lunikeza isisombululo esithembekileyo nesihlala ixesha elide esinika ukhuseleko olubalaseleyo kunye nexabiso elikhulu lemali.
