Inqubo ye-Rubber compounding kanye nokucubungula ubuchwepheshe

Ubuchwepheshe bokucutshungulwa kwenjoloba buchaza inqubo yokuguqula izinto zokusetshenziswa ezilula zibe yimikhiqizo yerabha enezakhiwo ezithile kanye nokubunjwa.Okuqukethwe okuyinhloko kuhlanganisa:

1. Isistimu yokuhlanganisa irabha:

Inqubo yokuhlanganisa irabha eluhlaza kanye nezithasiselo ngokusekelwe kuzimfuneko zokusebenza komkhiqizo, kucatshangelwa izici ezifana nokusebenza kobuchwepheshe bokucubungula kanye nezindleko.Uhlelo lokuxhumanisa olujwayelekile luhlanganisa irabha eluhlaza, uhlelo lwe-vulcanization, uhlelo lokuqinisa, uhlelo lokuvikela, uhlelo lwe-plasticizer, njll. Ngezinye izikhathi luhlanganisa nezinye izinhlelo ezikhethekile ezifana ne-flame retardant, imibala, igwebu, i-anti-static, i-conductive, njll.

1) Irabha eluhlaza (noma esetshenziswa ngokuhlangana namanye ama-polymer): impahla yomzali noma impahla ye-matrix

2) Uhlelo lwe-Vulcanization: Uhlelo olusebenzisana ngamakhemikhali nama-macromolecules enjoloba, luguqule iraba isuka kumamacromolecule aqondile ibe isakhiwo senethiwekhi esinezinhlangothi ezintathu, ithuthukisa izakhiwo zenjoloba futhi iqinise i-morphology yayo.

I-3) Uhlelo lokugcwalisa ukuqinisa: Ukwengeza ama-ejenti aqinisayo afana ne-carbon black noma amanye ama-filler erabha, noma ukuthuthukisa izakhiwo zayo zemishini, ukuthuthukisa ukusebenza kwenqubo, noma ukunciphisa izindleko zomkhiqizo.

4) Uhlelo lokuvikela: Faka ama-anti-aging ukuze ubambezele ukuguga kwenjoloba futhi uthuthukise impilo yesevisi yemikhiqizo.

I-5) Uhlelo lwe-Plasticizing: kunciphisa ubulukhuni bomkhiqizo kanye ne-viscosity yerabha exubile, futhi kuthuthukisa ukusebenza kokucubungula.

1. Ubuchwepheshe bokucubungula irabha:

Kungakhathaliseki ukuthi yimuphi umkhiqizo werabha, kufanele udlule ezinqubweni ezimbili: ukuxuba kanye ne-vulcanization.Emikhiqizweni eminingi yenjoloba, njengamapayipi, amateyipu, amathayi, njll., kufanele futhi idlule ezinqubweni ezimbili: ukugoqa nokukhipha.Ngerabha eluhlaza ene-Mooney viscosity ephezulu, nayo idinga ukubunjwa.Ngakho-ke, inqubo eyisisekelo nebaluleke kakhulu yokucubungula ekucubunguleni irabha ihlanganisa izigaba ezilandelayo:

I-1) Ukucwenga: ukunciphisa isisindo samangqamuzana enjoloba eluhlaza, ukwandisa ipulasitiki, nokuthuthukisa ukucutshungulwa.

2) Ukuxuba: Hlanganisa zonke izingxenye zefomula ngokulinganayo ukwenza irabha exubile.

3) Ukuginqika: Inqubo yokwenza imikhiqizo eqediwe kancane yezicaciso ezithile ngokuxuba irabha noma ukusebenzisa izinto zamathambo njengezindwangu nezintambo zensimbi ngokucindezela, ukubumba, ukubopha, ukusula, kanye nokusebenza kwe-gluing.

4) Ukucindezela: Inqubo yokucindezela imikhiqizo eqediwe enezingxenye ezihlukahlukene eziphambanayo, njengamashubhu angaphakathi, ukunyathela, izindonga eziseceleni, namapayipi enjoloba, ngaphandle kwerabha exubile ngokusebenzisa ukuma komlomo.

5) I-Vulcanization: Isinyathelo sokugcina sokucutshungulwa kwenjoloba, okubandakanya ukusabela kwamakhemikhali kwama-macromolecule enjoloba ukuze kukhiqizwe ukuxhumanisa ngemva kwezinga lokushisa elithile, ingcindezi, nesikhathi.
