Sebenzisa

Lo mkhiqizo awusetshenziselwa kuphela ukuhlanganiswa kwezinto eziphilayo, kodwa futhi usetshenziswa kabanzi njengefilimu ye-cellulose acetate, i-cellulose triacetate spinning, i-petroleum dewaxing, i-aerosol kanye nama-antibiotics, amavithamini, ama-steroids ekukhiqizeni izinyibilikisi, kanye ne-metal surface kapende yokuhlanza ungqimba wokuhlanza nokuhlubula i-ejenti. . Ngaphezu kwalokho, iphinde isetshenziselwe ukufuthwa okusanhlamvu kanye nesiqandisi samafriji anengcindezi ephansi kanye nama-air conditioners. Isetshenziswa njenge-ejenti yokuphefumula eyisiza ekukhiqizeni amagwebu e-Polyether urethane kanye ne-ejenti evuthelayo yamagwebu e-polysulfone akhishwe.

Ukuphepha

ubuthi buncane kakhulu, futhi ukwazi kuyashesha ngemva kokungenwa ubuthi, ngakho-ke kungasetshenziswa njengesibulali-zinzwa. Ukucasula isikhumba kanye nolwelwesi lwamafinyila. Amagundane amadala amancane aphuza ngomlomo ld501.6ml/kg. Isilinganiso esiphezulu esivumelekile emoyeni singama-500 × 10-6. Ukuhlinzwa kufanele kugqoke imaskhi yegesi, etholwe ngokushesha ngemva kokungenwa ushevu endaweni yesigameko, ukwelashwa okuwuphawu ngesigubhu sensimbi evalekile, 250kg umphongolo ngamunye, ithangi lesitimela imoto, imoto ingathuthwa. Kufanele igcinwe endaweni ebandayo emnyama eyomile, indawo enomoya omuhle, qaphela umswakama.
