Kusinthasintha kwa gudumu lamanja la mphira Kukhazikika kwake kwa rabara yaiwisi ndi makulidwe ake siwokwera kwambiri vulcanizate elasticity ndi yayikulu. Mwachitsanzo, mu osiyanasiyana 0-100 digiri C, kulimba mtima ndi pakati 50-85 digiri C, modulus elasticity ndi 1/3000 zitsulo, elongation ndi 1000%, elongation ndi 350% 15% mapindikidwe, mphira zachilengedwe dzanja gudumu mkulu elasticity, gudumu lamanja lachiwiri labala labala.
Mphamvu ya gudumu lamanja la mphira Muzinthu zotanuka, mphira wachilengedwe wamba mphira yaiwisi, mphira, mphamvu ya vulcanizate ndiyokwera kwambiri. Kulimba mphamvu ya unvulcanized mphira dzanja gudumu amatchedwa Green mphamvu, Green mphamvu zachilengedwe mphira handwheel mpaka 1.4 ~ 2.5Mpa, yoyenera Green mphamvu n'kofunika kuti processing wa akamaumba mphira dzanja gudumu. Mphamvu yachilengedwe ya mphira ya mphira ndi yokulirapo, mpaka 98kN / m, kukana kwake kulinso bwino. Chifukwa chomwe mphamvu yamakina a gudumu lamanja la mphira imakhala yokwera ndikuti ndi gudumu lodzilimbitsa yokha-lodzilimbitsa lomwe limapangitsa kuti unyolo wa macromolecular uwongolere kupsinjika ukatambasulidwa.
Electrical Properties of Natural Rubber Handwheels Mawilo apamanja a raba achilengedwe si-zinthu za polar ndipo ndi zoteteza bwino. Pamene masoka mphira dzanja gudumu vulcanized, chifukwa kumayambiriro zinthu polar, monga sulfure, accelerators, kuti kutchinjiriza katundu kuchepa.
Kusagwira ntchito kwa gudumu lamanja la mphira Wachilengedwe ndi wosakhala-ndi zinthu zaku polar, amasungunuka mu-zosungunulira zosungunulira ku polar komanso{2}}zopanda mafuta. Natural labala gudumu lamanja cyclohexane, petulo, benzene ndi zina, mphira unvulcanized akhoza kupasuka pamwamba sing'anga, vulcanized mphira dzanja gudumu ndi kutupa. Natural labala dzanja gudumu insoluble mu polar acetone, Mowa, koma zochepa sungunuka m'madzi, kugonjetsedwa ndi 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide ndi zina zotero.
Raba yaiwisi ya mphira wachilengedwe imakhala ndi kutentha kwa galasi la -72 digiri C., kutentha kwa kutentha kwa 130 ° C., kutentha koyambira kwa 200 ° C. ndi kutentha kwakukulu kwa kuwonongeka kwa 270 ° C. Pamene gudumu lamanja la mphira lachilengedwe likugwedezeka, Tg yake ikukwera, sikuchitikanso kutuluka kwa viscous.
Kuchita kwa gudumu lamanja la Bakelite:
PF Bakelite (Bakelite, bakelite) gudumu la m'manja lowala kwambiri, kulimba kolimba sikumapindika mosavuta, kukana ma abrasion, kusachita dzimbiri, kuletsa-kukalamba, kupukuta kosavuta. Bakelite handwheel kutchinjiriza ntchito ndi wamphamvu kwambiri ndipo si pansi kutentha ndi chinyezi, bakelite handwheel kutentha kupotoza kutentha kuposa / wofanana ndi madigiri 140, kuzizira hardiness akhoza kugwira ntchito malo abwino opanda madigiri makumi atatu.
