Injoloba yemvelo ingahlukaniswa ibe okunamathelayo kukagwayi, okunamathelayo okujwayelekile, okunamathelayo kwe-crepe, kanye ne-latex ngokwezinqubo ezihlukene zokukhiqiza kanye nokuma.Ingcina kagwayi iyahlungwa, iqiniswe ibe amashidi amancane ngokungeza i-formic acid, yomisiwe futhi ibhenywe ukuze kukhiqizwe Ishidi Elibhemayo Elibhemayo (RSS) .Iningi lenjoloba yemvelo elandwa lisuka eShayina iyingcina kagwayi, ngokuvamile ehlukaniswa ngokwendlela ebukeka ngayo futhi ihlukaniswe ngamaleveli amahlanu: RSS1, RSS2, RSS3, RSS4, RSS5, njll. ihlukaniswa njenge-adhesive yangaphandle.Irabha evamile i-latex eqinisiwe futhi yacutshungulwa yaba yizinhlayiya.Irabha yemvelo yasekhaya ngokuyisisekelo iyirabha ejwayelekile, eyaziwa nangokuthi irabha eyizinhlayiyana.Izinamatheliso ezijwayelekile zasekhaya (i-SCR) zivame ukuhlukaniswa ngokuya ngezakhiwo ezihlangene zomhlaba wonke namakhemikhali kanye nezinkomba, ezihlanganisa izinto eziyisikhombisa: okuqukethwe ukungcola, inani lokuqala lepulasitiki, izinga lokugcinwa kwepulasitiki, okuqukethwe kwe-nitrogen, okuqukethwe okuguquguqukayo, okuqukethwe komlotha, kanye nenkomba yombala.Phakathi kwazo, okuqukethwe kokungcola kusetshenziswa njengenkomba ye-conductivity, futhi ihlukaniswe ngamaleveli amane ngokusekelwe enanini lokungcola: SCR5, SCR10, SCR20, SCR50, njll., okulingana neyokuqala, yesibili, yesithathu, neyesine. izinamatheliso ezijwayelekile ezisezingeni e-China.Irabha yemvelo etholakala emakethe ngokuyinhloko yenziwa nge-latex ngezihlahla zenjoloba zamaqabunga amathathu.U-91% kuya ku-94% wezakhi zawo ama-hydrocarbon enjoloba, kanti ezinye izinto ezingezona zerabha ezifana namaprotheni, ama-acids anamafutha, umlotha, noshukela.Irabha yemvelo iyona esetshenziswa kakhulu emhlabeni wonke.Irabha yemvelo yenziwe nge-latex, futhi ingxenye yezingxenye ezingezona zerabha eziqukethwe ku-latex zihlala kunjoloba yemvelo eqinile.Ngokuvamile, irabha yemvelo iqukethe ama-hydrocarbons erabha angama-92% kuya ku-95%, kanti ama-hydrocarbon angewona amarabha athatha u-5% kuya ku-8%.Ngenxa yezindlela ezihlukene zokukhiqiza, umsuka, ngisho nezinkathi zokuvuna zenjoloba ezihlukene, ingxenye yalezi zingxenye ingase yehluke, kodwa ngokuvamile ingaphakathi kwebanga.Amaphrotheni angakhuthaza ukukhishwa kwenjoloba futhi alibazise ukuguga.Ngakolunye uhlangothi, amaprotheni anamandla okumunca amanzi, angakwazi ukwethula irabha ukuze imunce umswakama kanye nesikhunta, inciphise ukufakwa kwesikhumba, futhi ibe nenkinga yokwandisa ukukhiqizwa kokushisa.Izicucu ze-acetone zingamanye ama-fatty acids athuthukile kanye nama-sterol, amanye awo asebenza njengemvelo. ama-antioxidant nama-accelerators, kuyilapho abanye bengasiza ekuhlakazeni izithasiselo eziyimpuphu ngesikhathi sokuxuba futhi kuthambise irabha eluhlaza.Umlotha uqukethe usawoti onjenge-magnesium phosphate ne-calcium phosphate, enenani elincane lezinhlanganisela zensimbi njengethusi, i-manganese, nensimbi.Ngenxa yokuthi lawa ma-ion ensimbi e-valence angakhuthaza ukuguga kwerabha, okuqukethwe kwawo kufanele kulawulwe.Okuqukethwe komswakamo kwirabha eyomile akudluli u-1% futhi kungahwamuka ngesikhathi sokucubungula.Kodwa-ke, uma okuqukethwe komswakama kuphezulu kakhulu, akwenzi nje kuphela ukuthi irabha eluhlaza ikwazi ukubumba ngesikhathi sokugcinwa, kodwa futhi ithinta ukucubungula kwerabha, njengokuthambekela kwe-agent ehlanganisiwe ukuze ihlanganise ngesikhathi sokuxuba;Phakathi nenqubo yokugoqa kanye ne-extrusion, ama-bubbles akhiqizwa kalula, kuyilapho ngesikhathi senqubo ye-vulcanization, ama-bubbles noma isipontshi njengezakhiwo ezikhiqizwayo.
