Cellulose Acetate Butyrate, yomwe chidule chake ndi CAB, ili ndi formula ya mankhwala (C6H10O5) n ndi kulemera kwa molekyulu ya mamiliyoni ambiri. Ndi chinthu chonga ufa cholimba chomwe chimasungunuka mu zinthu zina zachilengedwe, monga acetic acid ndi acetic acid. Kusungunuka kwake kumawonjezeka ndi kutentha kowonjezereka. Cellulose acetate butyrate imakhalanso ndi kukhazikika kwa kutentha ndipo siiwonongeka mosavuta kutentha kwa chipinda.

Cellulose Acetate Butyrate ili ndi zinthu zabwino kwambiri monga kukana chinyezi, kukana UV, kukana kuzizira, kusinthasintha, kuwonekera bwino, komanso kutchinjiriza magetsi, ndipo imagwirizana bwino ndi ma resin ndi ma plasticizer okhala ndi malo otentha kwambiri. Mapulasitiki, ma substrates, mafilimu, ndi zokutira zokhala ndi zinthu zosiyanasiyana zimatha kupangidwa malinga ndi kuchuluka kwa butyryl. Itha kupangidwa ndi extrusion, jekeseni, rotary molding, blow molding, ndi zina zotero, kapena powiritsa. Kuphatikiza pa magulu a hydroxyl ndi acetyl, cellulose acetate butyrate ilinso ndi magulu a butyryl, ndipo zinthu zake zimagwirizana ndi kuchuluka kwa magulu atatu ogwira ntchito. Malo ake osungunuka ndi mphamvu yake yolimba zimawonjezeka ndi kuchuluka kwa acetyl, ndipo kugwirizana kwake ndi ma plasticizer ndi kusinthasintha kwa filimu kumawonjezeka mkati mwa mtundu wina ndi kuchepa kwa kuchuluka kwa acetyl. Kuwonjezeka kwa kuchuluka kwa hydroxyl kungathandize kusungunuka kwake mu polar solvents. Kuwonjezeka kwa kuchuluka kwa magulu a butyryl kumabweretsa kuchepa kwa kuchuluka ndi kufalikira kwa kuchuluka kwa kusungunuka.

Kugwiritsa Ntchito Cellulose Acetate Butyrate

Cellulose Acetate Butyrate imagwiritsidwa ntchito ngati chinthu choyezera komanso chopangira filimu popanga mawonekedwe owonekera bwino komanso ma substrate apulasitiki, mafilimu, ndi zokutira zosiyanasiyana zomwe sizingawonongeke ndi nyengo. Kuwonjezeka kwa kuchuluka kwa magulu a butyryl kumapangitsa kuchepa kwa kuchuluka kwa zinthu komanso kukulitsa kuchuluka kwa kusungunuka. Ili ndi magulu a acetyl 12% mpaka 15% ndi magulu a butyryl 26% mpaka 29%. Zinthu zowonekera kapena zosawoneka bwino, zokhala ndi kapangidwe kolimba komanso kukana kuzizira bwino. CAB ingagwiritsidwe ntchito ngati zinthu zopangira zinthu zopangira mafilimu, zinthu zopangira zithunzi zamlengalenga, mafilimu opyapyala, ndi zina zotero. Ingagwiritsidwenso ntchito ngati zinthu zopangira mapaipi, zogwirira zida, zingwe, zizindikiro zakunja, mabokosi a zida, ndi zina zotero. Kuphatikiza apo, ingagwiritsidwenso ntchito ngati zinthu zopangira zokutira zotsekeka, zokutira zoteteza kutentha, zokutira zapamwamba zopirira nyengo, ndi ulusi wopangira.

Makhalidwe a cellulose acetate butyrate

Cellulose acetate butyrate ili ndi makhalidwe apadera omwe amachititsa kuti izidziwike kwambiri mu ntchito zake. Choyamba, imatha kusungunuka bwino komanso kukhuthala, ndipo imatha kusakanikirana bwino ndi zinthu zina kuti igwire bwino ntchito. Kachiwiri, cellulose acetate butyrate ili ndi mphamvu zabwino zoyamwitsa chinyezi komanso kunyowetsa, zomwe zimatha kusunga chinyezi bwino komanso kukhazikika kwa zinthuzo. Kuphatikiza apo, imagwirizananso bwino ndi zinthu zina ndipo sidzakhala ndi zotsatirapo zoyipa pa thupi la munthu kapena chilengedwe.

Malangizo ogwiritsira ntchito cellulose acetate butyrate

Mukagwiritsa ntchito cellulose acetate butyrate, pali malangizo ndi njira zodzitetezera zomwe zingathandize kugwiritsa ntchito bwino ntchito yake. Choyamba, cellulose acetate butyrate iyenera kuumitsidwa musanagwiritse ntchito kuti isungunuke komanso ikhale yokhazikika. Kachiwiri, panthawi yokonza, kutentha kwambiri ndi acidity ziyenera kupewedwa kuti mupewe kuwonongeka ndi kuwonongeka kwa cellulose. Kuphatikiza apo, malamulo ndi malamulo oyenera ayenera kutsatiridwa mukamagwiritsa ntchito kuti zitsimikizire kuti zinthuzo zikutsatira malamulo ndi chitetezo.

Momwe mungaweruzire ubwino wa cellulose acetate butyrate

Ubwino wa cellulose acetate butyrate ukhoza kuweruzidwa kuchokera ku zinthu zotsatirazi. Choyamba, zitha kudziwika poyang'ana ngati mawonekedwe ake ndi ouma komanso opanda zodetsa zoonekeratu. Kachiwiri, kusungunuka ndi kukhazikika kwake zitha kuyesedwa, ndipo cellulose acetate butyrate yapamwamba iyenera kukhala ndi kusungunuka bwino komanso kukhazikika kwa kutentha. Kuphatikiza apo, ndizothekanso kunena za mbiri ndi udindo wa satifiketi ya ogulitsa ndikusankha ogulitsa odalirika komanso oyenerera kuti muwonetsetse kuti malonda ndi abwino komanso odalirika.

Unilong Industry yadzipereka ku kafukufuku wa ma ester a cellulose ndipo ndi kampani yapadziko lonse yopereka zinthu za CAB ndi CAP. Imatha kupanga matani 4000 a cellulose acetate propionate (CAP) ndi cellulose acetate butyrate (CAB) pachaka, ndipo imagwiritsidwa ntchito kwambiri pokonza zinthu zotumizira kunja monga zokutira, ma CD a chakudya, zoseweretsa za ana, zipangizo zachipatala, ndi zina zotero.
