Njira ya mphirandi mtundu wa mphira ndi zitsulo kapena CHIKWANGWANI gulu lamba lamba mphira, makamaka oyenera makina ulimi, makina zomangamanga ndi magalimoto zoyendera ndi mbali zina kuyenda.

Kukwera kwa zinthu zopangira zinthu

Thenjira ya mphiraili ndi magawo anayi: golide wapakati, wosanjikiza wamphamvu, wosanjikiza wa bafa ndi mphira. Pakati pawo, gawo la mphira limaphatikizapo guluu wambali, guluu woyambira, guluu wachitsulo, guluu wosanjikiza, guluu wosanjikiza nsalu, guluu la dzino, guluu wambali yamagudumu.

Golide wapakati ndi gawo lopatsirana, kutumiza mphamvu, chitsogozo ndi chithandizo chotsatira, zida zazikulu zomwe zimagwiritsidwa ntchito ndi chitsulo cha ductile, chitsulo chopangidwa ndi chitsulo, zitsulo zotayidwa, aloyi, mbale yachitsulo, etc., mayendedwe ena amatha kugwiritsa ntchito pulasitiki.

Chosanjikiza cholimba ndi gawo lokoka, lomwe ndi longitudinal tensile body ya rabara, yomwe imalimbana ndi mphamvu yokoka ndikusunga bata la njanji. Zida zazikulu zomwe zimagwiritsidwa ntchito ndi chingwe chachitsulo, waya wachitsulo, waya wachitsulo chosapanga dzimbiri, ulusi wagalasi, aramid kapena chingwe china champhamvu chotsika chotsika (chingwe) kapena chingwe.
Chophimbacho chimakhala ndi kugwedezeka kwamphamvu ndi kugwedezeka kwa thupi lamba, ndipo chimapirira mapindikidwe angapo omwe amayamba chifukwa cha mphamvu zozungulira, zozungulira komanso zowonongeka panthawi yoyendetsa njanji. Panthawi imodzimodziyo, imakhalanso chitetezo cha ziwalo zokoka, zomwe zimateteza mbali zowonongeka kuti zisawonongeke ndi mphamvu zakunja komanso zimalepheretsa kumenyana kwa waya wachitsulo wachitsulo cholimba kuchokera ku golide wapakati. Zida zazikulu zomwe zimagwiritsidwa ntchito ndi chingwe cha nayiloni, chinsalu cha nayiloni ndi zida zina za ulusi.

Themphira gawoimaphatikizanso zigawo zina zonse, kupereka kuthekera koyenda ndi kuwongolera kwathunthu, kuyamwa kugwedezeka ndi ntchito zochepetsera phokoso, zinthu zazikuluzikulu nthawi zambiri zimakhala mphira wachilengedwe (NR) based NR / styrene-butadiene rabara (SBR), NR / SBR / cis-butadiene mphira (BR), NR / mphira wosungunuka wa polystyrene-butadiene (SSBR) / BR ndi NR / BR kuphatikiza dongosolo ndi polyurethane elastomer.

Ogulitsa zinthu zofunika kwambiri monga mphira ndi waya wazitsulo amachokera ku China ndi Southeast Asia, Europe, United States ndi madera ena olemera kwambiri.
