TOP 5 Elastomers ya Gasket & Ikidodo Porogaramu
Elastomers ni iki?Ijambo rikomoka kuri "elastique" -imwe mubintu byingenzi bya reberi.Ijambo "rubber" na "elastomer" rikoreshwa mu buryo bumwe kugirango ryerekane polymers zifite viscoelasticity bakunze kwita "elastique."Imiterere yihariye ya elastomers harimo guhinduka, kuramba cyane hamwe no guhuza imbaraga hamwe no kugabanuka (damping numutungo wa reberi itera guhindura ingufu za mashini mubushuhe mugihe ziterwa no gutandukana).Iyi mitungo idasanzwe ituma elastomers ari ikintu cyiza kuri gasketi, kashe, izigunga ors, nibindi nkibyo.
Mu myaka yashize, umusaruro wa elastomer wimutse uva muri reberi karemano yatanzwe kuva igiti latex ikajya ikorwa cyane na reberi ikomatanya itandukanye.Mugukora ibyo bitandukanye, imitungo yihariye igerwaho hifashishijwe inyongeramusaruro nkuzuza cyangwa plastiseri cyangwa nukugereranya ibintu bitandukanye muburyo bwa copolymer.Ubwihindurize bwumusaruro wa elastomer utera ibintu byinshi bishoboka bya elastomer bishobora kuba injeniyeri, gukora kandi bigakorwa kumasoko.
Kugirango uhitemo ibikoresho bikwiye, umuntu agomba kubanza gusuzuma ibipimo rusange byerekana imikorere ya elastomer mugikapu no gushiraho kashe.Mugihe uhitamo ibikoresho bifatika, injeniyeri akenshi bagomba gufata ibintu byinshi mukuzirikana.Imiterere ya serivisi nkubushyuhe bwimikorere, ibidukikije, guhuza imiti, nibisabwa mubukanishi cyangwa kumubiri byose bigomba gusuzumwa neza.Ukurikije porogaramu, iyi serivise irashobora kugira ingaruka cyane kumikorere no kuramba kwa gaze ya elastomer cyangwa kashe.
Hamwe nibi bitekerezo, reka dusuzume eshanu muri elastomers ikoreshwa cyane kuri gasketi hamwe na kashe.
