Ngaphantsi kweengubo zangaphantsi kunokuba ngumncedi wenene ebusika. Into ephambili kukuba ukhethe ngokuchanekileyo, ngokokufunayo oko, ngokuba ukubunjwa kweengubo zangaphantsi ezitshatileyo kuyahluka ngokupheleleyo, kunye neendawo zayo, kuxhomekeke ekubunjweni. Izambatho zangaphantsi ezisebushushu zingenziwa zizinto zombini kunye nezinto zokwenza izinto, kwaye ngokuqhelekileyo zihlala zidibaniswe ngokweenqanaba ezahlukeneyo, bobabini nabanye. Ngokomzekelo, iipropropylene zangasese zangaphantsi zentsimbi, eziyimpahla yokwenza izinto, zithandwa kakhulu. Ziziphi iingenelo kunye nokungalungi? Makhe sicinge.
Polypropylene entambo zangaphantsi
Ngokuqhelekileyo, inzuzo enkulu yeelinen ezenziwe kwizinto zokwenziwa (nayiphi na) kukuba loo nto ityhila kakuhle kwaye ayifuni ukuqokelela umswakama, ngoko ke akunakwenzeka ukuba uphuthuke kwiingubo zangaphantsi ezinjalo nangethuba lokuzilolonga umzimba. Ukongezelela, iingubo zokubumba azivumeli ukuba iibhaktheriya zande, ngoko emva kokuqeqesha isikhumba sakho asiyi kuba nevumba elimnandi. Kwaye kunye neengubo zangaphantsi ezitshatileyo ezivela kwiingubo zokwenza izinto azizange zikhubazeke kwaye azidibanisi ngokukhawuleza njengalezo ndlela ezinokuthi zineepesenti eziphezulu zekotoni okanye iboya. Ekubeni zonke ezi mpawu, sinokuthi ngokuqinisekileyo ukuba kwabo bahlanganyela kwimidlalo baze baqhube ubomi obusebenzayo, iingubo zangaphantsi ezitshatileyo ziya kuba yinto ekhethekileyo.
Ngokukodwa, i-polypropylene njengangoku ithathwa njengenye yezinto ezifanelekileyo zokuzonwabisa . Kungcono kunamanye amacebo ukususa umswakama kwesikhumba, ngelixa lingenamanzi, ukwenzela ukuba kwiingubo ezinjalo uya kukhululeka. Kwakhona, i-polypropylene ine-conductivity ephantsi ye-thermal conductivity, ngoko ukushisa okuveliswa ngumzimba wakho kuya kuqhubeka, kungakuvumeli ukuba ukhululeke.
Ukungahambi kakuhle kwe-thermo-liner equkethe i-100% ye-polypropylene kukuba ngezwane ezinde, iqala ukomisa isikhumba. Ngako oko, gqoka iingubo zangaphantsi ezinyanzelisayo kwaye uchithe ngaphambi kokulala.
