Cellulose Acetate Butyrate, e khutsufalitsoeng e le CAB, e na le foromo ea lik'hemik'hale (C6H10O5) n le boima ba limolek'hule ba limilione. Ke ntho e tiileng e kang phofo e qhibilihang ka har'a li-solvents tse ling tsa tlhaho, tse kang acetic acid le acetic acid. Ho qhibiliha ha eona hoa eketseha ha mocheso o ntse o eketseha. Cellulose acetate butyrate le eona e na le botsitso bo itseng ba mocheso 'me ha e bole habonolo mochesong oa kamore.

Cellulose Acetate Butyrate e na le thepa e ntle haholo e kang ho hanyetsa mongobo, ho hanyetsa UV, ho hanyetsa serame, ho tenyetseha, ho pepeneneng le ho thibela motlakase, 'me e lumellana hantle le li-resin le li-plasticizer tse nang le ntlha e phahameng ea ho belisa. Liplastiki, li-substrate, lifilimi le lipente tse nang le thepa e fapaneng li ka etsoa ho latela litaba tse fapaneng tsa butyryl. E ka etsoa ka ho ntša metsi, ho enta ka ente, ho etsa molding o potolohang, ho etsa molding o phatsimang, jj., kapa ka ho belisa ka ho fafatsa. Ntle le lihlopha tsa hydroxyl le acetyl, cellulose acetate butyrate e boetse e na le lihlopha tsa butyryl, 'me thepa ea eona e amana le litaba tsa lihlopha tse tharo tse sebetsang. Ntlha ea eona ea ho qhibiliha le matla a ho tensile lia eketseha ka keketseho ea litaba tsa acetyl, 'me ho lumellana ha eona le li-plasticizer le ho tenyetseha ha filimi hoa eketseha ka har'a mefuta e itseng ka ho fokotseha ha litaba tsa acetyl. Keketseho ea litaba tsa hydroxyl e ka khothalletsa ho qhibiliha ha eona li-solvents tsa polar. Keketseho ea litaba tsa lihlopha tsa butyryl e fella ka ho fokotseha ha bongata le katoloso ea mefuta ea ho qhibiliha.

Tšebeliso ea Cellulose Acetate Butyrate

Cellulose Acetate Butyrate e sebelisoa e le sesebelisoa sa ho lekanya le ho etsa filimi bakeng sa ho hlahisa ponaletso e phahameng le li-substrate tsa polasetiki tse hanyetsanang le boemo ba leholimo, lifilimi le li-coat tse fapaneng. Keketseho ea litaba tsa lihlopha tsa butyryl e fella ka phokotso ea bongata le katoloso ea mefuta ea ho qhibiliha. E na le lihlopha tsa acetyl tse 12% ho isa ho 15% le lihlopha tsa butyryl tse 26% ho isa ho 29%. Thepa e bonaletsang kapa e sa bonahaleng ea granular, e nang le sebopeho se thata le ho hanyetsa serame hantle. CAB e ka sebelisoa e le thepa e tala bakeng sa ho lokisa li-substrate tsa filimi, li-substrate tsa lifoto tsa moeeng, lifilimi tse tšesaane, jj. E ka boela ea sebelisoa e le thepa e tala bakeng sa ho tsamaisa liphaephe, li-handles tsa lisebelisoa, likhoele, matšoao a kantle, mabokose a lisebelisoa, jj. Ho phaella moo, e ka boela ea sebelisoa e le thepa e tala bakeng sa ho hlahisa li-coat tse ka petsohang, li-coat tse thibelang mocheso, li-coat tse phahameng tse hanelang boemo ba leholimo, le likhoele tsa maiketsetso.

Litšobotsi tsa cellulose acetate butyrate

Cellulose acetate butyrate e na le litšobotsi tse ikhethang tse etsang hore e tsejoe haholo lits'ebetsong. Taba ea pele, e na le ho qhibiliha hantle le ho absorbability e ntle, 'me e ka kopanngoa ka botlalo le lisebelisoa tse ling ho fihlela ts'ebetso e ntle ea ts'ebetso. Taba ea bobeli, cellulose acetate butyrate e na le thepa e ntle ea ho monya mongobo le ho nolofatsa mongobo, e ka bolokang mongobo le botsitso ba thepa ka katleho. Ho feta moo, e boetse e na le ho lumellana hantle ha biochemical 'me e ke ke ea ba le litlamorao tse mpe' meleng oa motho kapa tikolohong.

Tlhahiso ea tšebeliso ea cellulose acetate butyrate

Ha o sebedisa cellulose acetate butyrate, ho na le ditlhahiso le mehato e meng e ka thusang ho sebedisa tshebetso ya yona ka botlalo. Taba ya pele, cellulose acetate butyrate e lokela ho omiswa pele e sebediswa ho ntlafatsa ho qhibiliha ha yona le botsitso ba yona. Taba ya bobedi, nakong ya tshebetso, maemo a mocheso o phahameng le a asiti a lokela ho qojwa ho thibela ho bola le ho senyeha ha cellulose. Ho feta moo, melao le melao e amehang e tlameha ho latelwa nakong ya tshebediso ho netefatsa hore thepa e latela melao le polokeho.

Mokhoa oa ho ahlola boleng ba cellulose acetate butyrate

Boleng ba cellulose acetate butyrate bo ka ahloloa ho latela lintlha tse latelang. Taba ea pele, e ka fumanoa ka ho hlahloba hore na ponahalo ea eona e omme ebile ha e na litšila tse totobetseng. Taba ea bobeli, ho qhibiliha ha eona le botsitso ba eona li ka lekoa, 'me butyrate ea acetate ea cellulose ea boleng bo holimo e lokela ho ba le ho qhibiliha ho hotle le botsitso ba mocheso. Ho phaella moo, hoa khoneha ho sheba botumo le boemo ba setifikeiti ba bafepedi le ho khetha bafepedi ba nang le botumo le ba tšoanelehang ho netefatsa boleng le ts'epo ea sehlahisoa.

Indasteri ea Unilong e ikemiselitse ho etsa lipatlisiso tsa li-ester tsa cellulose 'me ke mofani oa lefats'e oa lihlahisoa tsa CAB le CAP. E ka hlahisa lithane tse 4000 tsa cellulose acetate propionate (CAP) le cellulose acetate butyrate (CAB) selemo le selemo, 'me e sebelisoa haholo ts'ebetsong ea lihlahisoa tse romelloang kantle ho naha tse kang lipente, liphutheloana tsa lijo, lintho tsa ho bapala tsa bana, thepa ea bongaka, jj.
