Zomatira zachilengedwe zimatha kugawidwa kukhala zomatira ku ndudu, zomatira wamba, zomatira za crepe, ndi latex molingana ndi njira zosiyanasiyana zopangira ndi mawonekedwe. . Zambiri mwa mphira wachilengedwe wotumizidwa kuchokera ku China ndi zomatira fodya, zomwe nthawi zambiri zimagawidwa malinga ndi mawonekedwe ake ndipo zimagawidwa m'magulu asanu: RSS1, RSS2, RSS3, RSS4, RSS5, etc. Ngati sichifika pamlingo wachisanu, ndiye kuti ndi osankhidwa ngati zomatira zakunja.Rabara yokhazikika ndi latex yomwe yakhazikika ndikusinthidwa kukhala tinthu tating'onoting'ono. Labala wapakhomo ndi mphira wamba, womwe umadziwikanso kuti particle rabara. Zomatira zapakhomo (SCR) nthawi zambiri zimagawidwa molingana ndi zinthu zomwe zimagwirizanitsidwa padziko lonse lapansi ndi mankhwala ndi zizindikiro, zomwe zimaphatikizapo zinthu zisanu ndi ziwiri: zonyansa, mtengo wapulasitiki woyambirira, kuchuluka kwa kusungirako pulasitiki, kuchuluka kwa nayitrogeni, zinthu zosasinthika, phulusa, ndi index yamitundu. Zina mwazo, zonyansa zimagwiritsidwa ntchito ngati ndondomeko ya conductivity, ndipo zimagawidwa m'magulu anayi kutengera kuchuluka kwa zonyansa: SCR5, SCR10, SCR20, SCR50, etc., yomwe ili yofanana ndi yoyamba, yachiwiri, yachitatu, ndi yachinayi. zomatira mulingo wamba ku China.Rabara yachilengedwe yomwe imapezeka pamsika imapangidwa makamaka ndi latex kuchokera kumitengo itatu ya rabara yamasamba. 91% mpaka 94% ya zigawo zake ndi ma hydrocarbon a rabara, pomwe ena onse ndi zinthu zopanda mphira monga mapuloteni, mafuta acids, phulusa, ndi shuga. Labala lachilengedwe ndilo mphira wogwiritsidwa ntchito kwambiri padziko lonse lapansi. Labala lachilengedwe limapangidwa kuchokera ku latex, ndipo gawo la zinthu zomwe sizili za mphira zomwe zili mu latex zimakhalabe mu mphira wolimba wachilengedwe. Nthawi zambiri, mphira wachilengedwe amakhala ndi ma hydrocarbon 92% mpaka 95% a rabara, pomwe ma hydrocarbon omwe si amphira amakhala ndi 5% mpaka 8%. Chifukwa cha njira zosiyanasiyana zopangira, zoyambira, komanso nyengo zokolola labala zosiyanasiyana, kuchuluka kwa zigawozi kumatha kusiyanasiyana, koma nthawi zambiri zimakhala mkati mwazopanga.Mapuloteni amatha kulimbikitsa kuphulika kwa mphira ndikuchedwa kukalamba. Kumbali inayi, mapuloteni amakhala ndi madzi amphamvu, omwe amatha kuyambitsa mphira kuti atenge chinyezi ndi nkhungu, kuchepetsa kutsekemera, komanso kukhala ndi vuto la kuwonjezeka kwa kutentha kwa kutentha. antioxidants ndi accelerators, pamene ena angathandize kumwaza zowonjezera ufa pa kusakaniza ndi kufewetsa yaiwisi mphira. Phulusa makamaka mchere monga magnesium phosphate ndi calcium phosphate, yokhala ndi zinthu zochepa zachitsulo monga mkuwa, manganese, ndi chitsulo. Chifukwa ma ion zitsulo amtundu wa valence amatha kulimbikitsa ukalamba wa rabara, zomwe zili mkati mwake ziyenera kulamulidwa.Chinyezi cha rabara youma sichidutsa 1% ndipo chimatha kusungunuka panthawi yokonza. Komabe, ngati chinyezi chili chochuluka kwambiri, sichimangopangitsa kuti mphira yaiwisi ikhale yowonongeka panthawi yosungiramo, komanso imakhudzanso kukonza kwa mphira, monga chizolowezi chophatikizira chophatikizira panthawi yosakaniza; Pakugubuduza ndi extrusion ndondomeko, thovu mosavuta kwaiye, pamene pa ndondomeko vulcanization, thovu kapena siponji ngati nyumba amapangidwa.
