Mphira wachilengedwe ndi polymer yachilengedwe yokhala ndi polysoprene ngati chinthu chachikulu. Mawonekedwe ake a molecular ndi (C5h8) n. 91% mpaka 94% ya zigawo zamitundu yake ndi hydrocarbons (polyusoprene), ndipo ena onse ndi ma protein, rabara) ndi mphira wogwiritsidwa ntchito kwambiri.
Chovala comprosite: rababite chimatanthawuza kuti zomwe zili mu mphira wachilengedwe ndi 95% -99.5%, ndi rabadi Rabara woyengeka.
Dzina lachi China: kupanga mphira
Dzina la Chingerezi: Kupanga mphira
Tanthauzo: Zinthu zopangidwa mwaluso kwambiri ndi kusokonekera kosinthika kutengera ndi mankhwala a polymer.
●Gulu la mphira
Mbekeni amagawidwa m'magulu atatu: mphira wachilengedwe, rabara wapansi, ndi ranti lakodzola.
Pakati pawo, mphira wachilengedwe ndi mphira ndi mitundu ikuluikulu yomwe timayitanitsa; Ziphuphu zopangidwa zimatanthauza omwe amachotsedwa ku mafuta, motero sitilingalire kuti nthawi yake.
Mphira wa rabara (chilengedwe cha chilengedwe) amatanthauza mphira wopangidwa ndi rabani zopanga zachilengedwe. Mbewu yophika imapangidwa ndi kusakaniza mphira wachilengedwe wokhala ndi mphira pang'ono ndi mankhwala ena.
● mphira wachilengedwe
Rabara wachilengedwe imagawidwa mu rabara oyenerera ndi rabani yosuta mosiyanasiyana malinga ndi njira zosiyanasiyana zopangira. Mphira ndi woyenerera rabara. Mwachitsanzo, kerani wa China
Guluu wamtunduwu limakhalanso ndi masukulu osiyanasiyana, monga svr3l, SVR 5, SVR10, SVR20, SVR 50 ... etc.; Malinga ndi kukula kwa chiwerengerochi, chiwerengerochi, choyipacho; Ocheperako, nambala yabwinoyo (chinthu chofunikira kwambiri pakusiyanitsa pakati pa chabwino ndi choyipa ndicho phulusa ndi kudedwa, phulusa locheperako).
Guluu wosuta ndi pepala losuta, lomwe limatanthawuza chidutswa chochepa cha mphira wosuta, wofupikidwa ngati RSS. Chidule ichi ndi chosiyana ndi gulukulu lokhazikika, ndipo silili lofanana ndi malo, ndipo mawuwo ndi ofanana m'malo osiyanasiyana.
Palinso magulu osiyanasiyana osuta pepala, RSS1, RSS2, RSS3, RSS4, RSS5, RSS1, RSS1 ndi yabwino kwambiri, RSS5 ndiye mkhalidwe woyipa kwambiri.
● compatiza mphira
Amapangidwa mwa kusakaniza ndikuyenga mphira yachilengedwe ndi kapangidwe kakang'ono ka mankhwala ena. Njira yogwiritsidwa ntchito kwambiri yomwe imagwiritsidwa ntchito kwambiri ndi iyi, monganso rabiya ya ku Malawi yopanga pafupifupi 97% ya SMR 20 (Fyrey Verby) + 2,5% sbr (styrene butadiene rabara, 0,5% stearic acid).
Mpira wambiri umadalira mphira wachilengedwe womwe umapanga gawo lake lalikulu. Amatchedwa comphu. Monga pamwambapa, gawo lalikululi ndi SMR 20, ndiye kuti imatchedwa Malaysia No. 20 Coberse ya mphira; Palinso mapepala okhala ndi fodya ndi phula la mphira.
