Zingwe zopangira mphira zakhala zikugwiritsidwa ntchito m'makampani kwazaka zopitilira 100, zomwe zimapangidwa makamaka ndi kutentha kwamoto (makamaka kudzera munjira ya vulcanization tank) yolimba komanso yolimba kwambiri kuti ipititse patsogolo kukana kwa dzimbiri komanso kugwira ntchito kwake.Ndi chitukuko cha zipangizo za polima, mitundu yosiyanasiyana ya mphira yopanga ndi zipangizo zina zakhala zikugwiritsidwa ntchito pang'onopang'ono muzitsulo za rabara, zomwe zimapangitsa kuti zisagwirizane ndi asidi, alkali, mafuta, kutentha, mphamvu, komanso zotanuka kwambiri.
Ndi mphira wamtundu wanji womwe umagwiritsidwa ntchito ngati nsalu?
Mitundu iwiri ikuluikulu ya mphira imagwiritsidwa ntchito ngati zida zomangira: mphira wachilengedwe ndi mphira wopangira
Mpira Wachilengedwe:Zovala za rabara zachilengedwe zimakhala ndi mitundu yosiyanasiyana ya rabala ya polyethylene.Mitundu ya mphira iyi imadziwika ndi kuuma kochepa, kulimba kwambiri, kusinthasintha kwabwino komanso kutha kuyamwa ndi kuthamangitsa zowononga zazinthu zomwe akugwira.
ZopangidwaRubber:Raba wopangidwa monga butyl, hypalon, neoprene ndi nitrile amakana bwino ma hydrocarbon ndi mafuta amchere.
Mitundu yonse iwiri ya mphira ili ndi ubwino ndi zovuta zake, kotero mtundu womwe umagwiritsidwa ntchito ngati nsalu yotchinga udzadalira zosowa zenizeni za ntchitoyo.
M'mapulogalamu ena, kuvala ndi dzimbiri ndizovuta zomwe zingayambitse kulephera kwa zida, nthawi yocheperako komanso kukonza zodula.Kupaka mphira wabwino kwambiri kungapereke chitetezo chogwira mtima, kuwonjezera moyo wautumiki wa zida ndi kuchepetsa ndalama zokonzera.Mafakitale ambiri amafunikira mphira wokhazikika komanso wokhazikika kuti athe kuthana ndi zovuta zogwirira ntchito, ndipo kukana ma abrasion ndikofunikira kuganizira poyesa njira zotetezera zida.Kupaka mphira kumatanthawuza kugwiritsa ntchito mphira wosamva kuvala, woletsa dzimbiri komanso wosatentha kwambiri ngati mphira mkati mwa zida kapena mapaipi.Zakuthupi ndi mankhwala a mphira wokha amachepetsa mphamvu ya sing'anga yonyamulidwa ndi zipangizo pa kapangidwe kake.
Mwa kusintha payipi wa constituent zipangizo ndi kupanga ndondomeko, tikhoza mwamakondandipayipi pazofunikira zenizeni komanso momwe chilengedwe chikugwiritsidwira ntchito, zoyeserera zoyenera ndi kuyezetsa zimachitidwanso kuti zitsimikizire kuti payipi yokhazikika imatha kukwaniritsa zosowa zantchito ndikuchita zofunikira.Monga kampani yodziwika bwino pakupanga ndi kupanga ma hoses a rabara, CDSR yadzipereka kupatsa makasitomala ma hoses apamwamba a rabara ndi njira zosinthira makonda.
