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. CAB ingasetyenziswa njengento ekrwada ukulungiselela substrates film, substrates ukufota emoyeni, films obhityileyo, njl. Isenokusetyenziswa njengezinto ekrwada yokuhambisa imibhobho, izibambo isixhobo, iintambo, imiqondiso yangaphandle, iibhokisi isixhobo, njl Ukongeza, inokusetyenziswa kwakhona njengento ekrwada ukuvelisa ukutyabeka peelable, ukwaleka inkangeleko kunye ne-coatings high, i-coatings, i-coating, i-coating, i-coating, i-coatings, i-coatings, i-coatings, i-coatings, kunye ne-coatings.

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.
