Kusiyana pakati pa mphira wachilengedwe ndi mphira wophatikizika

Rabala yachilengedwe ndi pulasitiki yachilengedwe yokhala ndi polyisoprene ngati gawo lalikulu. Fomula yake ya molekyulu ndi (C5H8)n. 91% mpaka 94% ya zigawo zake ndi ma hydrocarbon a rabala (polyisoprene), ndipo zina zonse ndi mapuloteni, Zinthu zopanda rabala monga mafuta acids, phulusa, shuga, ndi zina zotero. Rabala yachilengedwe ndi rabala yomwe imagwiritsidwa ntchito kwambiri pazinthu zambiri.
Rabala ya Composite: Rabala ya Composite imatanthauza kuti kuchuluka kwa rabala yachilengedwe ndi 95%-99.5%, ndipo kuchuluka pang'ono kwa stearic acid, rabala ya styrene-butadiene, rabala ya butadiene, rabala ya isoprene, zinc oxide, carbon black kapena peptizer kumawonjezedwa. Rabala ya compound yoyengedwa bwino.
Dzina lachi China: mphira wopangidwa
Dzina la Chingerezi: rabala yopangidwa
Tanthauzo: Chovala chotanuka kwambiri chokhala ndi kusintha kosinthika kochokera ku mankhwala opangidwa ndi polima.

●Gulu la rabala
Rabala imagawidwa m'magulu atatu: rabala lachilengedwe, rabala lopangidwa ndi zinthu zosiyanasiyana, ndi rabala lopangidwa ndi zinthu zosiyanasiyana.

Pakati pawo, mphira wachilengedwe ndi mphira wophatikizika ndi mitundu ikuluikulu yomwe timaitanitsa kunja pakadali pano; mphira wopangidwa umatanthauza womwe umachotsedwa mu mafuta, kotero sitidzauganizira pakadali pano.

Rabala yachilengedwe (rabala yachilengedwe) imatanthauza rabala yopangidwa kuchokera ku zomera zopanga rabala yachilengedwe. Rabala yophatikizika imapangidwa posakaniza rabala yachilengedwe ndi rabala yopangidwa pang'ono ndi mankhwala ena.

● Rabala lachilengedwe

Rabala yachilengedwe imagawidwa m'zigawo za rabala yokhazikika ndi yosuta malinga ndi njira zosiyanasiyana zopangira. Rabala yokhazikika ndi rabala yokhazikika. Mwachitsanzo, rabala yokhazikika ya ku China ndi rabala yokhazikika ya ku China, chidule chake ndi SCR, ndipo mofananamo pali SVR, STR, SMR ndi zina zotero.

Guluu wamba ulinso ndi mitundu yosiyanasiyana, monga SVR3L, SVR 5, SVR10, SVR20, SVR 50… ndi zina zotero; malinga ndi kukula kwa nambala, nambala ikakhala yayikulu, khalidwe lake limakhala loipa kwambiri; nambala ikakhala yaying'ono, khalidwe lake limakhala labwino kwambiri (chofunika kwambiri kusiyanitsa pakati pa chabwino ndi choipa. Chinthu chachikulu ndi phulusa ndi kuipitsidwa kwa chinthucho, phulusa likakhala lochepa, khalidwe lake limakhala labwino kwambiri).

Guluu wa pepala losuta ndi Ribbed Smoked Sheet, yomwe imatanthauza chidutswa choonda cha rabara yosuta, chofupikitsidwa ngati RSS. Chidule ichi ndi chosiyana ndi guluu wamba, ndipo sichigawidwa malinga ndi malo opangira, ndipo mawu ake ndi ofanana m'malo osiyanasiyana opangira.

Palinso mitundu yosiyanasiyana ya guluu wosuta, RSS1, RSS2, RSS3, RSS4, RSS5, zomwezo, RSS1 ndiyenso wabwino kwambiri, RSS5 ndiye woipa kwambiri.

● Rabala yopangidwa ndi zinthu zosiyanasiyana

Amapangidwa posakaniza ndi kuyeretsa rabala lachilengedwe ndi rabala lopangidwa pang'ono ndi mankhwala ena. Fomula ya rabala lopangidwa kwambiri ndi iyi, monga rabala lopangidwa ku Malaysia la SMR Compounded Rubber 97% SMR 20 (rabala lokhazikika la ku Malaysia) + 2.5% SBR (rabala la styrene butadiene, rabala lopangidwa) + 0.5% stearic acid acid).

Rabala ya compound imadalira rabala yachilengedwe yomwe imapanga gawo lake lalikulu. Imatchedwa compound. Monga tafotokozera pamwambapa, gawo lalikulu ndi SMR 20, kotero imatchedwa Malaysia No. 20 standard rabala compound; palinso smoke sheet compound ndi standard rabala compound.
