izindaba

I-Cellulose Acetate Butyrate, efushaniswe ngokuthi i-CAB, inefomula yamakhemikhali (C6H10O5) n kanye nesisindo sama-molecule esiyizigidi. Iyinto efana nempuphu eqinile encibilikayo kwezinye izinyibilikisi eziphilayo, njenge-acetic acid kanye ne-acetic acid. Ukuncibilika kwayo kuyanda ngokushisa okwandayo. I-Cellulose acetate butyrate nayo inokuqina okuthile kokushisa futhi ayiboli kalula ekushiseni kwegumbi.

I-Cellulose Acetate Butyrate inezakhiwo ezinhle kakhulu njengokumelana nomswakama, ukumelana ne-UV, ukumelana nokubanda, ukuguquguquka, ukucaca, kanye nokufakwa kukagesi, futhi ihambisana kahle nama-resin kanye nama-plasticizer aphezulu okubila. Amapulasitiki, ama-substrate, amafilimu, kanye nokumbozwa okunezakhiwo ezahlukene kungenziwa ngokwezinto ezahlukene ze-butyryl. Ingakhiwa ngokuphuma, ukubumba ngomjovo, ukubumba okujikelezayo, ukubumba ngokufutha, njll., noma ngokufutha ngokubilisa. Ngaphezu kwamaqembu e-hydroxyl kanye ne-acetyl, i-cellulose acetate butyrate nayo iqukethe amaqembu e-butyryl, futhi izakhiwo zayo zihlobene nokuqukethwe kwamaqembu amathathu asebenzayo. Indawo yayo yokuncibilika kanye namandla okuthamba kuyanda ngokwanda kokuqukethwe kwe-acetyl, futhi ukuhambisana kwayo nama-plasticizer kanye nokuguquguquka kwefilimu kuyanda ngaphakathi kobubanzi obuthile ngokuncipha kokuqukethwe kwe-acetyl. Ukwanda kokuqukethwe kwe-hydroxyl kungakhuthaza ukuncibilika kwayo kuma-solvents e-polar. Ukwanda kokuqukethwe kwamaqembu e-butyryl kuphumela ekwehleni kobuningi kanye nokwanda kobubanzi bokuncibilika.

Ukusetshenziswa kwe-Cellulose Acetate Butyrate

I-Cellulose Acetate Butyrate isetshenziswa njenge-ejenti yokulinganisa kanye ne-film-forming substrates yokukhiqiza ukukhanya okuphezulu kanye ne-plastic substrates enhle yokumelana nesimo sezulu, amafilimu, kanye ne-coatings ehlukahlukene. Ukwanda kokuqukethwe kwamaqembu e-butyryl kuholela ekunciphiseni kobuningi kanye nokwanda kobubanzi bokuncibilika. Iqukethe amaqembu e-acetyl angu-12% kuya ku-15% kanye namaqembu e-butyryl angu-26% kuya ku-29%. Izinto ezibonakalayo noma ezingacacile, ezine-texture eqinile kanye nokumelana okuhle nokubanda. I-CAB ingasetshenziswa njengezinto zokusetshenziswa zokulungiselela i-substrates zamafilimu, i-substrates ze-aerial photography, amafilimu amancane, njll. Ingasetshenziswa futhi njengezinto zokusetshenziswa zokuhambisa amapayipi, izibambo zamathuluzi, izintambo, izimpawu zangaphandle, amabhokisi amathuluzi, njll. Ngaphezu kwalokho, ingasetshenziswa futhi njengezinto zokusetshenziswa zokukhiqiza i-coatings ehlubukayo, i-insulation coatings, i-high-end-end-high-end coatings, kanye ne-fairs yokwenziwa.

Izici ze-cellulose acetate butyrate

I-Cellulose acetate butyrate inezici ezithile ezihlukile ezenza iqashelwe kabanzi ekusetshenzisweni kwayo. Okokuqala, inokuncibilika okuhle kanye nokunamathela kahle, futhi ingaxutshwa ngokuphelele nezinye izinto ukuze kufezwe ukusebenza okuhle kokucubungula. Okwesibili, i-cellulose acetate butyrate inezici ezinhle zokumunca umswakama kanye nokuthambisa umswakama, okungagcina ngempumelelo umswakama kanye nokuqina kwezinto. Ngaphezu kwalokho, futhi ihambisana kahle nezinto eziphilayo futhi ngeke ibe nemiphumela emibi emzimbeni womuntu noma endaweni ezungezile.

Isiphakamiso sokusetshenziswa kwe-cellulose acetate butyrate

Uma usebenzisa i-cellulose acetate butyrate, kuneziphakamiso nezinyathelo zokuphepha ezingasiza ekusebenziseni ngokugcwele ukusebenza kwayo. Okokuqala, i-cellulose acetate butyrate kufanele yomiswe ngaphambi kokusetshenziswa ukuze kuthuthukiswe ukuncibilika kwayo kanye nokuqina kwayo. Okwesibili, ngesikhathi sokucubungula, kufanele kugwenywe izimo zokushisa eziphakeme kanye ne-acidic ukuze kuvinjelwe ukubola kanye nokuwohloka kwe-cellulose. Ngaphezu kwalokho, imithetho nemithetho efanele kumele ilandelwe ngesikhathi sokusetshenziswa ukuqinisekisa ukuhambisana nokuphepha kwezinto.

Indlela yokwahlulela ikhwalithi ye-cellulose acetate butyrate

Ikhwalithi ye-cellulose acetate butyrate ingahlulelwa ngezici ezilandelayo. Okokuqala, inganqunywa ngokuhlola ukuthi ukubukeka kwayo komile futhi akunazo yini izinto ezingcolisayo ezisobala. Okwesibili, ukuncibilika kwayo nokuqina kwayo kungahlolwa, futhi i-cellulose acetate butyrate esezingeni eliphezulu kufanele ibe nokuncibilika okuhle nokuqina kokushisa. Ngaphezu kwalokho, kungenzeka futhi ukubhekisela edumeleni kanye nesimo sesitifiketi sabahlinzeki bese ukhetha abahlinzeki abathembekile nabafanelekayo ukuqinisekisa ikhwalithi yomkhiqizo nokuthembeka.

I-Unilong Industry izibophezele ocwaningweni lwama-cellulose esters futhi ingumhlinzeki womhlaba wonke wemikhiqizo ye-CAB ne-CAP. Ingakhiqiza amathani angu-4000 e-cellulose acetate propionate (CAP) kanye ne-cellulose acetate butyrate (CAB) minyaka yonke, futhi isetshenziswa kabanzi ekucutshungulweni kwemikhiqizo yokuthumela kwamanye amazwe efana nokumbozwa, ukupakishwa kokudla, amathoyizi ezingane, izinto zokwelapha, njll.
