Tikamagwiritsa ntchito makina okhala ndi maziko achitsulo, kuti titeteze pamwamba pa msewu komanso kuti sitima zachitsulo zisamathe kunyamula katundu, nthawi zambiri timasankha kuyika nsapato za rabara kapena zolembera za rabara pa njanji. Masiku ano, tidzasankha kutengera zinthu zomwe zili mu zolembera za rabara.
Pakadali pano, zipangizo za rabara zomwe zimagwiritsidwa ntchito popanga maziko a njanji pamsika nthawi zambiri zimakhala ndi rabara ndi polyurethane. Chifukwa chake chisankho chachikulu pakati pa ziwirizi n'chosavuta: m'mikhalidwe yovuta yogwirira ntchito, cholinga chathu ndi kukhala ndi moyo wautali kwambiri, ndipo timakonda polyurethane; pamalo otsetsereka kuti tigwire ntchito, timafunika mphamvu yogwira ntchito kwambiri, kenako kusankha rabara kaye.
※ Ngati mukufuna nthawi yayitali yogwirira ntchito komanso yolimba kwambiri yokana kukalamba: sankhani polyurethane (PU)
· Kukana kwa polyurethane kuwonongeka ndi kuwirikiza katatu mpaka khumi kuposa kwa rabala, ndipo nthawi yake yogwirira ntchito imatha kukhala kuwirikiza kawiri mpaka katatu kuposa kwa rabala.
· Ndi yolimba kung'ambika ndi kudula, ili ndi mphamvu yolimba yonyamulira, ndipo ndi yamphamvu kuwirikiza kawiri kuposa rabara. Ndi yoyenera makina opera misewu ndi zida zamigodi m'malo ogwirira ntchito olemera.
· Sizimatha kugwidwa ndi mafuta ndi hydrolysis, sizimakalamba kapena kusweka mosavuta, ndipo zimakhala ndi kutentha kwakukulu kogwira ntchito (-30°C mpaka 80°C).
※Ngati malo ogwirira ntchito ndi oterera kapena chitetezo cha pamsewu chikufunika: sankhani rabala
· Ili ndi kapangidwe kofewa ndipo imatha kugwira bwino kwambiri pamalo otsetsereka onyowa kapena odzaza madzi.
· Ili ndi kusinthasintha kwabwino ndipo imatha kuyamwa bwino zinthu zogwedezeka kuti iteteze dongosolo la chassis.
· Siziwononga kwambiri msewu ndipo ndizoyenera kugwiritsa ntchito malo opaka miyala omwe amagwira ntchito pa phula, simenti kapena malo oimika magalimoto a njerwa.
※Zoganizira za mtengo
· Mtengo woyambira kugula: Rabala nthawi zambiri imakhala yotsika mtengo ndi pafupifupi 25% kuposa polyurethane.
· Mtengo wokwanira wogwiritsira ntchito: Ngakhale kuti polyurethane ili ndi ndalama zambiri zoyambira (30% - 50%), nthawi yake yogwirira ntchito imatha kuchepetsa kuchuluka kwa nthawi yosinthira ndi nthawi yopuma, ndipo pamapeto pake, ikhoza kukhala ndi ndalama zambiri zogwirira ntchito.
Nayi njira yoti mutsatire njira yachidule: Choyamba mutha kuwunika momwe zida zimagwirira ntchito.
· Pa ntchito zovuta monga migodi, ngalande, malo otsetsereka, kapena makina okhala ndi zinthu zolemera, polyurethane (PU) ndiyo njira yabwino kwambiri.
· Pa zipangizo zomwe zimafunika kugwira malo otsetsereka monga misewu yonyowa kapena malo otsetsereka, kapena pa makina oyendetsera misewu ya phula monga ma pavers, rabala ndiye njira yabwino kwambiri.
Mwachidule, podziwa ngati mumayang'ana kwambiri moyo wautali (kusankha polyurethane) kapena chogwirira (kusankha rabala), ndikuganizira kusankha zinthu zonse za chassis yonse, mutha kupeza yankho lomwe likugwirizana bwino ndi zosowa zanu zogwirira ntchito!
