Kagwiritsidwe Ntchito
polyisobutene (hydrogenated) ndi mankhwala ochepetsa ululu.
Polyisobutylene, yomwe nthawi zina imatchedwa butyl rabara, ndipo nthawi zina PIB, ndi vinyl polymer. Ndi yofanana kwambiri ndi polyethylene ndi polypropylene mu kapangidwe kake, koma kuti carbon ina iliyonse imalowetsedwa m'malo ndi magulu awiri a methyl. Imapangidwa kuchokera ku monomer isobutylene, pogwiritsa ntchito cationic vinyl polymerization.
Polyisobutylene ndi rabala yopangidwa ndi zinthu zopangidwa, kapena elastomer. Ndi yapadera chifukwa ndi rabala yokhayo yomwe singalowe mpweya. Ndiko kuti, ndi rabala yokhayo yomwe imatha kusunga mpweya kwa nthawi yayitali. Mwina mwazindikira kuti mabaluni amatha kuphwa patatha masiku angapo. Izi zili choncho chifukwa amapangidwa ndi polyisoprene, yomwe singathe kulowa mpweya. Chifukwa polyisobutylene imasunga mpweya, imagwiritsidwa ntchito popanga zinthu monga machubu amkati, matayala amkati, ndi ma liners amkati a basketball.
Kulongedza ndi Kutumiza
180KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
