Ukusetshenziswa
i-polyisobutene (hydrogenated) iyi-emollient.
I-Polyisobutylene, ngezinye izikhathi ebizwa ngokuthi i-butyl rubber, kanti ngezinye izikhathi i-PIB, iyi-vinyl polymer. Ifana kakhulu ne-polyethylene ne-polypropylene ngesakhiwo, ngaphandle kokuthi yonke enye ikhabhoni ithathelwa indawo amaqembu amabili e-methyl. Yenziwe nge-monomer isobutylene, nge-cationic vinyl polymerization.
I-Polyisobutylene iyirabha yokwenziwa, noma i-elastomer. Ikhethekile ngoba iyona kuphela irabha engangenwa yigesi. Okusho ukuthi, iyona kuphela irabha engabamba umoya isikhathi eside. Kungenzeka ukuthi uqaphele ukuthi amabhaluni azophela ngemva kwezinsuku ezimbalwa. Lokhu kungenxa yokuthi enziwe nge-polyisoprene, okungeyona igesi engangenwa yigesi. Ngenxa yokuthi i-polyisobutylene izobamba umoya, isetshenziselwa ukwenza izinto ezifana namapayipi angaphakathi, izingqimba zamathayi, kanye nezingqimba zangaphakathi zama-basketball.
Ukupakisha Nokuthumela
180KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
