I-Shellac CAS 9000-59-3
I-Shellac inezakhiwo ezinhle kakhulu njengokuvikela umswakama, ukuvimbela ukugqwala, ukuvimbela ukugqwala, ukumelana nowoyela, ukufakwa kukagesi kanye ne-thermoplastic. I-solvent engcono kakhulu yamaphilisi e-shellac ama-alcohol asezingeni eliphansi aqukethe i-hydroxyl, njenge-methanol ne-ethanol. Ayincibiliki ku-glycol ne-glycerol, i-soluble ku-lye, i-ammonia, kodwa futhi incibilika kuma-acids aphansi e-carboxylic, njenge-formic acid ne-acetic acid, engancibiliki emafutheni, ama-hydrocarbon anephunga elimnandi nokuphuma kwawo kwe-halogen, i-carbon tetrachloride, amanzi, isixazululo samanzi sesulfure dioxide. I-Shellac resin iyabola endaweni yemvelo. Ukukhishelwa emanzini kuzodala ukwanda kokuqukethwe kwe-oksijini yezinto eziphilayo zamanzi, kwenze i-eutrophication yamanzi, futhi kwenze amanzi abe bomvu ngokwenzwa.

I-1.Embonini yokudla, i-shellac iphinde isetshenziswe emigqonyeni yokugcina izithelo ukuze yenze amafilimu aqhakazile, ikhulise impilo yeshalofu yezithelo, futhi ikhulise inani lazo lokuhweba. I-Shellac isetshenziswa ku-confectionery kanye ne-pastry coatings ukuze kwandiswe ukukhanya, kuvimbele ukubuya komswakama, futhi kugcotshwe izindonga zangaphakathi zamathini ensimbi ukuze kuvinjwe ukudla ukuthi kungathintani nensimbi.
I-2.Shellac ingasetshenziswa kabanzi ekudleni, emithini, ezempi, kagesi, uyinki, isikhumba, insimbi, imishini, izinkuni, irabha, nezinye izimboni.
Upende we-3.Shellac unokunamathela okuqinile futhi usetshenziswa ezintweni eziningi zokhuni eziphezulu kanye nemihlobiso.
I-4.Shellac isetshenziswa embonini yesikhumba njengesiphetho esikhanyayo nesivikelayo, esibonakala ngokumisa okusheshayo, ukugcwaliswa okuqinile, nokunamathela okuqinile kwesikhumba, okwenza kube lula futhi kunwebeka.
5. Embonini kagesi, i-shellac iphinde isetshenziswe ekwakhiweni kwe-insulating paperboard, amabhodi e-mica laminated, ama-insulators kagesi aphansi, ama-varnishes, ama-bulb, izibani ze-fluorescent, nama-solder pastes amashubhu kagesi.
6.Embonini yezempi, i-shellac isetshenziswa kakhulu njenge-retarder ye-coating agents, izinto zokuvikela, kanye nezidakamizwa zesibhamu. I-Shellac iphinde isetshenziselwe ukwenza imishini yezempi engavimbeli i-UV kanye nemisebe.
I-7.I-Shellac isetshenziswa ngokuyinhloko njenge-surface coating noma i-filler yemikhiqizo yerabha embonini yenjoloba. Thuthukisa ukuguga, uwoyela, i-asidi, amanzi, kanye nokugqumisa. Yehlisa inqubo yokuguga futhi welule isikhathi sokuphila.
20 kg/ibhokisi, 50 kg/isikhwama noma ngokwezidingo zamakhasimende.
