Ukusetyenziswa
i-polyisobutene (hydrogenated) iyathambisa umzimba.
I-Polyisobutylene, ngamanye amaxesha ebizwa ngokuba yi-butyl rubber, kwaye ngamanye amaxesha i-PIB, yi-vinyl polymer. Ifana kakhulu ne-polyethylene kunye ne-polypropylene ngendlela eyakhiwe ngayo, ngaphandle kokuba yonke enye ikhabhoni ithathelwa indawo ngamaqela amabini e-methyl. Yenziwe nge-monomer isobutylene, nge-cationic vinyl polymerization.
I-Polyisobutylene yirabha yokwenziwa, okanye i-elastomer. Ikhethekile kuba yeyona rabha kuphela engenagesi. Oko kukuthi, yeyona rabha kuphela enokubamba umoya ixesha elide. Usenokuba uqaphele ukuba iibhaluni ziya kuba buthathaka emva kweentsuku ezimbalwa. Oku kungenxa yokuba zenziwe nge-polyisoprene, engenakungenwa yigesi. Ngenxa yokuba i-polyisobutylene iya kubamba umoya, isetyenziselwa ukwenza izinto ezifana neetyhubhu zangaphakathi, iileya zeethayara, kunye nee-inner liners zeebhasikithi.
Ukupakishwa kunye nokuthunyelwa
180KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
