iindaba

I-Cellulose Acetate Butyrate, efinyeziweyo njenge-CAB, inefomyula yekhemikhali (C6H10O5) n kunye nobunzima beemolekyuli ezizigidi. Yinto efana nomgubo oqinileyo onyibilikayo kwezinye izinyibilikisi ze-organic, ezifana ne-acetic acid kunye ne-acetic acid. Ukunyibilika kwayo kuyanda ngobushushu obukhulayo. I-Cellulose acetate butyrate ikwanayo nokuzinza okuthile kobushushu kwaye ayiboli lula kubushushu begumbi.

I-Cellulose Acetate Butyrate ineempawu ezintle kakhulu ezifana nokumelana nokufuma, ukumelana ne-UV, ukumelana nokubanda, ukuguquguquka, ukucaca, kunye nokufakelwa kombane, kwaye ihambelana kakuhle neeresini kunye neeplastiki eziphezulu zokubilisa. Iiplastiki, ii-substrates, iifilimu, kunye neengubo ezineempawu ezahlukeneyo zinokwenziwa ngokwemixholo eyahlukeneyo ye-butyryl. Inokwenziwa ngokuphuma, ukubumba ngenaliti, ukubumba okujikelezayo, ukubumba ngokuvuthela, njl.njl., okanye ngokubilisa ngokutshiza. Ukongeza kumaqela e-hydroxyl kunye ne-acetyl, i-cellulose acetate butyrate ikwanamaqela e-butyryl, kwaye iimpawu zayo zinxulumene nomxholo wamaqela amathathu asebenzayo. Indawo yayo yokunyibilika kunye namandla okutsalwa ayanda ngokunyuka komxholo we-acetyl, kwaye ukuhambelana kwayo neeplastiki kunye nokuguquguquka kwefilimu kuyanda ngaphakathi koluhlu oluthile ngokuhla komxholo we-acetyl. Ukwanda komxholo we-hydroxyl kunokukhuthaza ukunyibilika kwayo kwiisolvents ze-polar. Ukwanda komxholo wamaqela e-butyryl kubangela ukwehla koxinano kunye nokwandiswa koluhlu lokunyibilika.

Ukusetyenziswa kweCellulose Acetate Butyrate

I-Cellulose Acetate Butyrate isetyenziswa njenge-arhente yokulinganisa kunye ne-film-forming substrates ukuvelisa ukukhanya okuphezulu kunye ne-substrates zeplastiki ezimelana kakuhle nemozulu, iifilimu, kunye nee-coatings ezahlukeneyo. Ukwanda komxholo wamaqela e-butyryl kubangela ukwehla koxinano kunye nokwandiswa koluhlu lokunyibilika. Iqulethe amaqela e-acetyl ali-12% ukuya kwi-15% kunye namaqela e-butyryl ali-26% ukuya kwi-29%. Izinto ezibonakalayo okanye ezingacacanga, ezinobume obuqinileyo kunye nokumelana nokubanda okuhle. I-CAB ingasetyenziswa njengezinto eziluhlaza ukulungiselela ii-substrates zefilimu, ii-substrates ze-aerial photography, ii-films ezincinci, njl. Ingasetyenziswa njengezinto eziluhlaza zokuhambisa imibhobho, izibambo zezixhobo, iintambo, imiqondiso yangaphandle, iibhokisi zezixhobo, njl. Ukongeza, ingasetyenziswa njengezinto eziluhlaza zokuvelisa ii-coatings ezixobukayo, ii-insulation coatings, ii-high-end-resistant coatings, kunye nee-fibers zokwenziwa.

Iimpawu ze-cellulose acetate butyrate

I-Cellulose acetate butyrate ineempawu ezikhethekileyo ezenza ukuba iqatshelwe ngokubanzi kwiindlela ezisetyenziswayo. Okokuqala, inokunyibilika kakuhle kwaye iyakwazi ukufunxa, kwaye ingaxutywa ngokupheleleyo nezinye izinto ukuze kufezekiswe ukusebenza kakuhle kokucubungula. Okwesibini, i-cellulose acetate butyrate ineempawu ezilungileyo zokufunxa umswakama kunye nokufunxa, ezinokugcina ngokufanelekileyo umswakama kunye nokuzinza kwezinto. Ukongeza, ikwanokuhambelana okuhle kwezinto eziphilayo kwaye ayiyi kuba nemiphumo emibi emzimbeni womntu okanye kwindalo esingqongileyo.

Ingcebiso yokusetyenziswa kwe-cellulose acetate butyrate

Xa usebenzisa i-cellulose acetate butyrate, kukho iingcebiso kunye namanyathelo okhuseleko anokunceda ekusebenziseni ngokupheleleyo ukusebenza kwayo. Okokuqala, i-cellulose acetate butyrate kufuneka yomiswe ngaphambi kokuba isetyenziswe ukuphucula ukunyibilika kwayo kunye nozinzo. Okwesibini, ngexesha lokucubungula, kufuneka kuthintelwe iimeko zobushushu obuphezulu kunye ne-asidi ukuthintela ukubola kunye nokuwohloka kwe-cellulose. Ukongeza, imigaqo kunye nemithetho efanelekileyo kufuneka ilandelwe ngexesha lokusetyenziswa ukuqinisekisa ukuthotyelwa kunye nokhuseleko lwezixhobo.

Indlela yokugweba umgangatho we-cellulose acetate butyrate

Umgangatho we-cellulose acetate butyrate unokugwetywa ngokwezi nkalo zilandelayo. Okokuqala, inokuqinisekiswa ngokujonga ukuba inkangeleko yayo yomile na kwaye ayinazo izinto ezingcolisayo ezicacileyo. Okwesibini, ukunyibilika kwayo kunye nozinzo lwayo kunokuvavanywa, kwaye i-cellulose acetate butyrate ekumgangatho ophezulu kufuneka ibe nokunyibilika okuhle kunye nozinzo lobushushu.
