Imikoreshereze
Polyisobutene (hydrogenated) ni umuti ugabanya ububabare.
Polyisobutylene, rimwe na rimwe yitwa butyl rubber, n'ubundi PIB, ni vinyl polymer. Isa cyane na polyethylene na polypropylene mu miterere yayo, uretse ko indi carbon yose isimbuzwa amatsinda abiri ya methyl. Ikorwa muri monomer isobutylene, binyuze muri cationic vinyl polymerization.
Polyisobutylene ni rubber ikoze mu buryo bwa sintetike, cyangwa elastomer. Ni umwihariko kuko ari yo rubber yonyine idashobora kuvomwa na gaze. Ni ukuvuga ko ari yo rubber yonyine ishobora kubika umwuka igihe kirekire. Ushobora kuba warabonye ko balloons zizashira nyuma y'iminsi mike. Ibi biterwa nuko zikozwe muri polyisoprene, ntabwo zidashobora kuvomwa na gaze. Kubera ko polyisobutylene izabika umwuka, ikoreshwa mu gukora ibintu nk'imiyoboro y'imbere, imiterere y'amapine, n'imirongo y'imbere y'imipira ya basketball.
Gupakira no Kohereza
180KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
