Kusiyana pakati pa mphira wachilengedwe ndi mphira wapawiri

Raba wachilengedwe ndi polima wachilengedwe wokhala ndi polyisoprene monga gawo lalikulu.Mapangidwe ake a molekyulu ndi (C5H8)n.91% mpaka 94% ya zigawo zake ndi raba hydrocarbons (polyisoprene), ndipo ena onse ndi mapuloteni, Non-raba zinthu monga mafuta zidulo, phulusa, shuga, etc. Natural labala ndi ambiri ntchito ambiri cholinga mphira.
Labala Yophatikizika: Labala yophatikizika imatanthawuza kuti mphira wachilengedwe ndi 95% -99.5%, ndipo kagawo kakang'ono ka stearic acid, mphira wa styrene-butadiene, mphira wa butadiene, mphira wa isoprene, okusayidi wa zinc, wakuda wakuda kapena peptizer amawonjezeredwa.Woyenga pawiri rabala.
Dzina lachi China: mphira wopangira
Dzina lachingerezi: mphira wopangira
Tanthauzo: Chinthu chotanuka kwambiri chokhala ndi mapindikidwe osinthika kutengera zinthu zopangidwa ndi polima.

●Gulu la mphira
Labala amagawidwa m'magulu atatu: mphira wachilengedwe, mphira wophatikizika, ndi mphira wopangira.

Pakati pawo, mphira wachilengedwe ndi mphira wophatikizika ndi mitundu ikuluikulu yomwe timaitanitsa pakali pano;mphira wopangidwa ndi mafuta opangidwa ndi petroleum, kotero sitingaganizirepo pano.

Labala wachilengedwe (rabala wachilengedwe) amatanthauza mphira wopangidwa kuchokera ku zomera zopanga mphira zachilengedwe.Labala wophatikizidwa amapangidwa posakaniza mphira wachilengedwe ndi mphira wopangira pang'ono ndi mankhwala ena.

● Labala wachilengedwe

Labala yachilengedwe imagawidwa kukhala mphira wokhazikika komanso mphira wosuta malinga ndi njira zosiyanasiyana zopangira.mphira wokhazikika ndi mphira wokhazikika.Mwachitsanzo, mphira wamba waku China ndi Standard rabara yaku China, yofupikitsidwa ngati SCR, ndipo mofananamo pali SVR, STR, SMR ndi zina zotero.

Guluu wokhazikika alinso ndi magiredi osiyanasiyana, monga SVR3L, SVR 5, SVR10, SVR20, SVR 50… etc.;malingana ndi kukula kwa chiwerengerocho, chiwerengerocho chikakulirakulira, chimakhala choyipa kwambiri;nambala yaying'ono, imakhala yabwino kwambiri (chinthu chofunika kwambiri chosiyanitsa chabwino ndi choipa Chinthu ndi phulusa ndi zonyansa zomwe zili ndi mankhwala, phulusa lochepa, khalidwe labwino).

Guluu wosuta ndi Ribbed Smoked Sheet, kutanthauza kachidutswa kakang'ono ka mphira wosuta, wofupikitsidwa ngati RSS.Chidule ichi ndi chosiyana ndi guluu wamba, ndipo sichimasankhidwa malinga ndi malo opangira, ndipo mawuwa ndi ofanana m'malo osiyanasiyana opanga.

Palinso magulu osiyanasiyana a guluu wosuta, RSS1, RSS2, RSS3, RSS4, RSS5, yemweyo, RSS1 ndiyenso yabwino kwambiri, RSS5 ndiye mtundu woyipa kwambiri.

● mphira wophatikizika

Amapangidwa ndi kusakaniza ndi kuyeretsa mphira wachilengedwe ndi mphira wopangira pang'ono ndi mankhwala ena.Njira yomwe imagwiritsidwa ntchito kwambiri ndi rabara ndi iyi, monga mphira wapawiri waku Malaysia SMR Compounded Rubber 97% SMR 20 (Malaysian standard rabara) + 2.5% SBR (rabara ya styrene butadiene, rabara yopangidwa) + 0.5% stearic acid).

Labala wophatikizika umadalira mphira wachilengedwe womwe umapanga chigawo chake chachikulu.Amatchedwa komponena.Monga pamwamba, chigawo chachikulu ndi SMR 20, choncho amatchedwa Malaysia No. 20 muyezo wa rabara pawiri;palinso ma sheet a utsi ndi mphira wamba wamba.
