iindaba

I-Cellulose Acetate Butyrate, efinyeziweyo njenge-CAB, ine-chemical formula (C6H10O5) n kunye ne-molecular weight yezigidi. Ngumgubo oqinileyo onjengento enyibilikayo kwezinye izinyibilikisi eziphilayo, ezifana neacetic acid kunye neacetic acid. Ukunyibilika kwayo kuyanda ngokunyuka kobushushu. I-Cellulose acetate butyrate nayo inozinzo oluthile lwe-thermal kwaye ayiboli lula kwiqondo lobushushu begumbi.

I-Cellulose Acetate Butyrate ineempawu ezibalaseleyo ezifana nokuxhathisa ukufuma, ukuxhathisa kwe-UV, ukumelana nokubanda, ukuguquguquka, ukungafihli, kunye nokugquma kombane, kwaye iyahambelana kakuhle ne-resins kunye ne-plasticizers ephezulu yokubilisa. Iiplastiki, i-substrates, iifilimu, kunye neengubo ezineepropathi ezahlukeneyo zingenziwa ngokwemixholo eyahlukeneyo ye-butyryl. Isenokwenziwa nge-extrusion, isitofu sokubumba, ukubumba okujikelezayo, ukubumba ukuvuthela, njl., okanye ngokubilisa ukutshiza. Ukongeza kumaqela e-hydroxyl kunye ne-acetyl, i-cellulose acetate butyrate nayo iqulethe amaqela e-butyryl, kwaye iimpawu zayo zihambelana nomxholo wamaqela amathathu asebenzayo. Inqanaba layo lokunyibilika kunye nokuqina kwamandla okunyuka kunye nokunyuka komxholo we-acetyl, kunye nokuhambelana kwayo kunye neeplastiki kunye nokuguquguquka kwefilimu ukunyuka ngaphakathi kwinqanaba elithile kunye nokunciphisa umxholo we-acetyl. Ukunyuka komxholo we-hydroxyl kunokukhuthaza ukunyibilika kwayo kwi-solvents ye-polar. Ukunyuka kumxholo wamaqela e-butyryl kubangela ukuhla kobuninzi kunye nokwandiswa koluhlu lokuchithwa.

Ukusetyenziswa kweCellulose Acetate Butyrate

I-Cellulose Acetate Butyrate isetyenziswa njenge-ejenti yokulinganisa kunye ne-film-forming substance ukuvelisa ukungafihli okuphezulu kunye nokumelana nemozulu elungileyo substrates zeplastiki, iifilimu, kunye neengubo ezahlukeneyo. Ukunyuka kumxholo wamaqela e-butyryl kubangela ukuhla kobuninzi kunye nokwandiswa koluhlu lokuchithwa. Iqulethe i-12% ukuya kwi-15% yamaqela e-acetyl kunye ne-26% ukuya kuma-29% amaqela e-butyryl. Izinto ezibonakalayo ezicacileyo okanye ze-opaque ze-granular, ezinobunzima obunzima kunye nokumelana nokubanda okulungileyo. I-CAB ingasetyenziswa njengento ekrwada yokulungisa ama-substrates efilimu, i-eriyali yokufota, iifilim ezibhityileyo, njl. njl. Ukongeza, isenokusetyenziswa njengento ekrwada ukuvelisa iileyiti ezicwebekileyo, i-insulation, i-insulation, ukumelana nemozulu ephezulu, kunye neentsinga ezenziweyo.

Iimpawu ze-cellulose acetate butyrate

I-Cellulose acetate butyrate ineempawu ezizodwa ezenza ukuba yaziwe ngokubanzi kwizicelo. Okokuqala, ine-solubility efanelekileyo kunye ne-adsorbability, kwaye inokuxutywa ngokupheleleyo nezinye izixhobo ukufezekisa ukusebenza kakuhle kokusetyenzwa. Okwesibini, i-cellulose acetate butyrate inokufunxeka kakuhle komswakama kunye neempawu zokuthambisa, ezinokugcina ngokufanelekileyo ukufuma kunye nokuzinza kwezinto. Ukongeza, ikwane-biocompatibility elungileyo kwaye ayiyi kuba neziphumo ezibi kumzimba womntu okanye kokusingqongileyo.

Isiphakamiso sokusetyenziswa kwe-cellulose acetate butyrate

Xa usebenzisa i-cellulose acetate butyrate, kukho iziphakamiso kunye nezilumkiso ezinokunceda ukusebenzisa ngokupheleleyo ukusebenza kwayo. Okokuqala, i-cellulose acetate butyrate kufuneka yomiswe ngaphambi kokusetyenziswa ukuphucula ukunyibilika kwayo nokuzinza. Okwesibini, ngexesha lokucubungula, ukushisa okuphezulu kunye neemeko ze-acidic kufuneka zigwenywe ukuthintela ukubola kunye nokuchithwa kwe-cellulose. Ukongezelela, imimiselo efanelekileyo kunye nemithetho kufuneka ilandelwe ngexesha lokusetyenziswa ukuqinisekisa ukuthotyelwa kunye nokhuseleko lwezixhobo.

Indlela yokugweba umgangatho we-cellulose acetate butyrate

Umgangatho we-cellulose acetate butyrate unokugwetywa kule miba ilandelayo. Okokuqala, inokumiselwa ngokujonga ukuba imbonakalo yayo yomile kwaye ayinakungcola okucacileyo. Okwesibini, ukunyibilika kwayo kunye nokuzinza kunokuvavanywa, kwaye umgangatho ophezulu we-cellulose acetate butyrate kufuneka ube ne-solubility efanelekileyo kunye nokuzinza kwe-thermal. Ukongeza, kuyenzeka ukuba ubhekisele kwisimo kunye nenqanaba lesatifikethi sababoneleli kwaye ukhethe ababoneleli abathembekileyo nabaqeqeshiweyo ukuqinisekisa umgangatho wemveliso kunye nokuthembeka.

I-Unilong Industry izibophelele kuphando lwee-cellulose esters kwaye ingumnikezeli wehlabathi jikelele we-CAB kunye neemveliso ze-CAP. Inokuvelisa iitoni ezingama-4000 ze-cellulose acetate propionate (CAP) kunye ne-cellulose acetate butyrate (CAB) ngonyaka, kwaye isetyenziswa ngokubanzi ekuqhutyweni kweemveliso ezithunyelwa ngaphandle ezifana neengubo, ukupakishwa kokutya, amathoyizi abantwana, izinto zonyango, njl.
