Irabha yemvelo iyinhlanganisela yemvelo ye-polymer ene-polyisoprene njengengxenye eyinhloko. Ifomula yayo yama-molecule ingu-(C5H8)n. 91% kuya ku-94% wezingxenye zayo zingama-hydrocarbon erabha (i-polyisoprene), kanti okunye kuyi-protein, Izinto ezingezona irabha ezifana nama-fatty acid, umlotha, ushukela, njll. Irabha yemvelo iyirabha esetshenziswa kakhulu ngenhloso ejwayelekile.
Irabha ehlanganisiwe: Irabha ehlanganisiwe isho ukuthi okuqukethwe kwerabha yemvelo kungu-95%-99.5%, futhi inani elincane le-stearic acid, irabha ye-styrene-butadiene, irabha ye-butadiene, irabha ye-isoprene, i-zinc oxide, i-carbon black noma i-peptizer kuyangezwa. Irabha ehlanganisiwe ecwengisisiwe.
Igama lesiShayina: irabha yokwenziwa
Igama lesiNgisi: irabha yokwenziwa
Incazelo: Izinto ezinwebeka kakhulu ezinokuguquguquka okuguqukayo okusekelwe kumakhemikhali e-polymer okwenziwa.
●Ukuhlukaniswa kwerabha
Irabha ihlukaniswe kakhulu ngezigaba ezintathu: irabha yemvelo, irabha ehlanganisiwe, kanye nerabha yokwenziwa.
Phakathi kwazo, irabha yemvelo kanye nerabha ehlanganisiwe yizinhlobo eziyinhloko esizingenisa kwamanye amazwe njengamanje; irabha yokwenziwa ibhekisela kulezo ezikhishwe kuphethiloli, ngakho ngeke siyicabangele okwamanje.
Irabha yemvelo (irabha yemvelo) ibhekisela kurabha eyenziwe ngezitshalo zemvelo ezikhiqiza irabha. Irabha ehlanganisiwe yenziwa ngokuxuba irabha yemvelo nerabha encane yokwenziwa kanye neminye imikhiqizo yamakhemikhali.
● Irabha yemvelo
Irabha yemvelo ihlukaniswe yaba irabha ejwayelekile kanye nerabha yeshidi elibhemayo ngokwezinqubo ezahlukene zokukhiqiza. Irabha ejwayelekile iyirabha ejwayelekile. Isibonelo, irabha ejwayelekile yaseShayina iyirabha ejwayelekile yaseShayina, efushaniswe ngokuthi i-SCR, futhi ngokufanayo kukhona i-SVR, i-STR, i-SMR njalo njalo.
Iglue ejwayelekile inamazinga ahlukene, njenge-SVR3L, SVR 5, SVR10, SVR20, SVR 50… njll.; ngokuya ngobukhulu benombolo, lapho inombolo inkulu, ikhwalithi iba yimbi; lapho inombolo incane, ikhwalithi iba ngcono (into ebaluleke kakhulu yokuhlukanisa phakathi kokuhle nokubi Isici ukuthi umlotha nokuqukethwe kokungcola komkhiqizo, lapho umlotha omncane, ikhwalithi iba ngcono).
Iglue yeshidi elibhemayo yiRibbed Smoked Sheet, ebhekisela ecezwini elincane lerabha elibhemayo, elifingqiwe njenge-RSS. Lesi sifinyezo sihlukile kuglue ejwayelekile, futhi asihlukaniswa ngokwendawo yokukhiqiza, futhi inkulumo iyafana ezindaweni ezahlukene zokukhiqiza.
Kukhona futhi amazinga ahlukene eglue ebhemayo, i-RSS1, i-RSS2, i-RSS3, i-RSS4, i-RSS5, okufanayo, i-RSS1 nayo iyikhwalithi engcono kakhulu, i-RSS5 iyikhwalithi embi kakhulu.
● Irabha ehlanganisiwe
Yenziwa ngokuxuba nokucwenga irabha yemvelo ngerabha encane yokwenziwa kanye neminye imikhiqizo yamakhemikhali. Ifomula yerabha ehlanganisiwe esetshenziswa kakhulu yile, njengerabha ehlanganisiwe yaseMalaysia i-SMR Compounded Rubber 97% SMR 20 (irabha ejwayelekile yaseMalaysia) + 2.5% SBR (irabha ye-styrene butadiene, irabha yokwenziwa) + 0.5% i-stearic acid acid).
Irabha ehlanganisiwe incike kurabha yemvelo eyakha ingxenye yayo eyinhloko. Ibizwa ngokuthi i-compound. Njengoba kushiwo ngenhla, ingxenye eyinhloko yi-SMR 20, ngakho-ke ibizwa ngokuthi i-compound ejwayelekile yerabha yaseMalaysia No. 20; kukhona futhi i-compound ye-smoke sheet kanye ne-compound ejwayelekile yerabha.
