izindaba

I-Cellulose Acetate Butyrate, efushanisiwe njenge-CAB, inefomula yamakhemikhali (C6H10O5) n kanye nesisindo samangqamuzana ezigidi. Kuyimpushana eqinile encibilika kwezinye izincibilikisi eziphilayo, njenge-acetic acid ne-acetic acid. Ukunyibilika kwayo kukhuphuka ngokukhuphuka kwezinga lokushisa. I-Cellulose acetate butyrate nayo inokuzinza okuthile kokushisa futhi ayiboli kalula ezingeni lokushisa legumbi.

I-Cellulose Acetate Butyrate inezici ezinhle kakhulu ezifana nokumelana nomswakama, ukumelana ne-UV, ukumelana nokubanda, ukuguquguquka, ukukhanya, kanye nokufakwa kukagesi, futhi inokuhambisana kahle nama-resin kanye nama-plasticizers aphezulu abilayo. Amapulasitiki, ama-substrates, amafilimu, nezingubo ezinezakhiwo ezahlukene zingenziwa ngokuvumelana nokuqukethwe okuhlukile kwe-butyryl. Ingakhiwa nge-extrusion, ukubumba umjovo, ukubumba okujikelezayo, ukubunjwa kokushaywa, njll., noma ngokufafaza abilayo. Ngaphezu kwamaqembu e-hydroxyl ne-acetyl, i-cellulose acetate butyrate nayo iqukethe amaqembu e-butyryl, futhi izakhiwo zayo zihlobene nokuqukethwe kwamaqembu amathathu asebenzayo. Iphuzu layo lokuncibilika namandla aqinile liyakhula ngokwanda kokuqukethwe kwe-acetyl, futhi ukuhambisana kwayo nama-plasticizers nokuvumelana nezimo kwefilimu kukhuphuka phakathi kwebanga elithile ngokuncipha kokuqukethwe kwe-acetyl. Ukwenyuka kokuqukethwe kwe-hydroxyl kungakhuthaza ukuncibilika kwayo kuzincibilikisi ze-polar. Ukwenyuka kokuqukethwe kwamaqembu e-butyryl kuholela ekwehleni kokuminyana kanye nokunwetshwa kwebanga lokuqedwa.

Ukusetshenziswa kwe-Cellulose Acetate Butyrate

I-Cellulose Acetate Butyrate isetshenziswa njenge-ejenti yokulinganisa kanye nento eyenza ifilimu ukuze kukhiqizwe ukukhanya okuphezulu kanye nama-substrates epulasitiki amelana nesimo sezulu esihle, amafilimu, nezingubo ezihlukahlukene. Ukwenyuka kokuqukethwe kwamaqembu e-butyryl kuholela ekwehleni kokuminyana kanye nokunwetshwa kwebanga lokuqedwa. Iqukethe 12% kuya ku-15% amaqembu e-acetyl kanye nama-26% kuya ku-29% amaqembu e-butyryl. Izinto ezibonakalayo ezibonisa ngale noma ezi-opaque, ezinokwakheka okuqinile nokumelana okuhle nokubanda. I-CAB ingasetshenziswa njengempahla yokusetshenziswa ekulungiseni ama-substrates amafilimu, ama-substrates ezithombe zasemoyeni, amafilimu amancanyana, njll. Ingasetshenziswa futhi njengezinto ezingavuthiwe zokudlulisa amapayipi, izibambo zamathuluzi, izintambo, izimpawu zangaphandle, amabhokisi amathuluzi, njll. Ngaphezu kwalokho, ingasetshenziswa futhi njengempahla eluhlaza yokukhiqiza ama-coatings axebukayo, ama-insulation coatings, ukumelana nesimo sezulu esiphezulu, kanye nemicu yokwenziwa.

Izici ze-cellulose acetate butyrate

I-Cellulose acetate butyrate inezici ezithile ezihlukile eziyenza yaziwe kabanzi ezinhlelweni zokusebenza. Okokuqala, inokunyibilika okuhle nokukhangayo, futhi ingaxutshwa ngokugcwele nezinye izinto ukuze kuzuzwe ukusebenza kahle kokucubungula. Okwesibili, i-cellulose acetate butyrate inendawo enhle yokumunca umswakama kanye nezindawo zokuswakama, ezingagcina ngempumelelo umswakama nokuzinza kwezinto. Ngaphezu kwalokho, iphinde ibe ne-biocompatibility enhle futhi ngeke ibe nemiphumela emibi emzimbeni womuntu noma endaweni ezungezile.

Isiphakamiso sokusetshenziswa kwe-cellulose acetate butyrate

Uma usebenzisa i-cellulose acetate butyrate, kuneziphakamiso ezithile nezinyathelo zokuphepha ezingasiza ukusebenzisa ngokugcwele ukusebenza kwayo. Okokuqala, i-cellulose acetate butyrate kufanele yomiswe ngaphambi kokusetshenziswa ukuze kuthuthukiswe ukunyibilika nokuzinza kwayo. Okwesibili, ngesikhathi sokucubungula, izinga lokushisa eliphezulu kanye nezimo ze-acidic kufanele kugwenywe ukuvimbela ukubola nokuwohloka kwe-cellulose. Ngaphezu kwalokho, imithetho nemithetho efanele kufanele ilandelwe ngesikhathi sokusetshenziswa ukuze kuqinisekiswe ukuhambisana nokuphepha kwezinto.

Ungahlulela kanjani ikhwalithi ye-cellulose acetate butyrate

Izinga le-cellulose acetate butyrate lingahlulelwa ngezici ezilandelayo. Okokuqala, inganqunywa ngokubheka ukuthi ukubukeka kwayo komile futhi akunakho ukungcola okusobala. Okwesibili, ukunyibilika kwayo nokuzinza kungahlolwa, futhi ikhwalithi ephezulu ye-cellulose acetate butyrate kufanele ibe nokuncibilika okuhle nokuzinza kokushisa. Ukwengeza, kuyenzeka futhi ukuthi ubheke isithunzi kanye nesimo sokuthola isitifiketi sabahlinzeki bese ukhetha abahlinzeki abahloniphekile nabaqeqeshiwe ukuze kuqinisekiswe ikhwalithi nokwethembeka komkhiqizo.

I-Unilong Industry izibophezele ocwaningweni lwama-cellulose esters futhi ingumhlinzeki womhlaba wonke wemikhiqizo ye-CAB ne-CAP. Ingakhiqiza amathani angu-4000 we-cellulose acetate propionate (CAP) kanye ne-cellulose acetate butyrate (CAB) minyaka yonke, futhi isetshenziswa kabanzi ekucubungulweni kwemikhiqizo ethunyelwa ngaphandle efana nezingubo, ukupakishwa kokudla, amathoyizi ezingane, izinto zokwelapha, njll.
