Ntxiv nrog rau hydroxyl thiab acetyl pawg, cellulose acetate butyrate kuj muaj butyryl pawg, thiab nws cov khoom muaj feem cuam tshuam nrog cov ntsiab lus ntawm peb pawg ua haujlwm. Nws lub ntsiab lus yaj thiab lub zog tensile nce nrog kev nce ntawm acetyl cov ntsiab lus, thiab nws qhov sib xws nrog cov plasticizers thiab yooj ywm ntawm zaj duab xis nce hauv qee qhov ntau nrog kev txo qis ntawm acetyl cov ntsiab lus. Kev nce hauv hydroxyl cov ntsiab lus tuaj yeem txhawb nws cov solubility hauv cov kuab tshuaj polar. Kev nce hauv cov ntsiab lus ntawm butyryl pawg ua rau muaj kev txo qis hauv qhov ceev thiab kev nthuav dav ntawm cov khoom yaj.
Daim Ntawv Thov ntawm Cellulose Acetate Butyrate
Cellulose Acetate Butyrate yog siv los ua tus neeg sawv cev rau kev sib npaug thiab cov tshuaj ua zaj duab xis rau kev tsim cov yas uas muaj pob tshab thiab tiv taus huab cua zoo, cov yeeb yaj kiab, thiab ntau yam txheej. Kev nce ntxiv ntawm cov ntsiab lus ntawm butyryl pawg ua rau qhov ceev txo qis thiab nthuav dav ntawm qhov ntau ntawm kev yaj. Muaj 12% txog 15% acetyl pawg thiab 26% txog 29% butyryl pawg. Cov khoom siv pob tshab lossis opaque granular, nrog cov qauv tawv thiab tiv taus txias zoo. CAB tuaj yeem siv ua cov khoom siv raw rau kev npaj cov zaj duab xis substrates, cov duab thaij duab saum huab cua, cov yeeb yaj kiab nyias, thiab lwm yam. Nws kuj tseem siv tau ua cov khoom siv raw rau kev xa cov kav dej, cov cuab yeej tuav, cov xov hlau, cov cim sab nraum zoov, cov thawv cuab yeej, thiab lwm yam. Tsis tas li ntawd, nws kuj tseem siv tau ua cov khoom siv raw rau kev tsim cov txheej txheej peelable, cov txheej txheej rwb thaiv tsev, cov txheej txheej siab tiv taus huab cua, thiab cov xov hlau dag.
Cov yam ntxwv ntawm cellulose acetate butyrate
Cellulose acetate butyrate muaj qee yam tshwj xeeb uas ua rau nws paub dav hauv kev siv. Ua ntej, nws muaj kev yaj zoo thiab kev nqus tau zoo, thiab tuaj yeem sib xyaw nrog lwm cov ntaub ntawv kom ua tiav kev ua haujlwm zoo tshaj plaws. Qhov thib ob, cellulose acetate butyrate muaj cov khoom nqus dej zoo thiab noo noo, uas tuaj yeem tswj tau cov av noo thiab ruaj khov ntawm cov khoom. Tsis tas li ntawd, nws kuj muaj kev sib raug zoo ntawm lub cev thiab yuav tsis muaj kev cuam tshuam tsis zoo rau tib neeg lub cev lossis ib puag ncig.
Cov lus qhia rau kev siv cellulose acetate butyrate
Thaum siv cellulose acetate butyrate, muaj qee cov lus qhia thiab kev ceev faj uas tuaj yeem pab siv nws cov kev ua tau zoo tag nrho. Ua ntej, cellulose acetate butyrate yuav tsum tau qhuav ua ntej siv kom txhim kho nws cov solubility thiab kev ruaj khov. Qhov thib ob, thaum lub sijhawm ua, yuav tsum zam qhov kub siab thiab cov kua qaub kom tiv thaiv kev lwj thiab kev puas tsuaj ntawm cellulose. Tsis tas li ntawd, cov cai thiab cov cai cuam tshuam yuav tsum tau ua raws li thaum siv kom ntseeg tau tias ua raws li thiab muaj kev nyab xeeb ntawm cov ntaub ntawv.
Yuav ua li cas txiav txim siab qhov zoo ntawm cellulose acetate butyrate
Qhov zoo ntawm cellulose acetate butyrate tuaj yeem txiav txim siab los ntawm cov hauv qab no. Ua ntej, nws tuaj yeem txiav txim siab los ntawm kev kuaj xyuas seb nws qhov tsos puas qhuav thiab tsis muaj cov khoom tsis huv. Qhov thib ob, nws cov solubility thiab stability tuaj yeem kuaj xyuas, thiab cov cellulose acetate butyrate zoo yuav tsum muaj solubility zoo thiab thermal stability. Tsis tas li ntawd, nws tseem tuaj yeem xa mus rau lub koob npe nrov thiab daim ntawv pov thawj ntawm cov neeg muag khoom thiab xaiv cov neeg muag khoom muaj npe nrov thiab tsim nyog kom ntseeg tau tias cov khoom zoo thiab kev ntseeg siab.
Unilong Kev Lag Luam tau cog lus rau kev tshawb fawb ntawm cellulose esters thiab yog tus muab kev pabcuam thoob ntiaj teb ntawm CAB thiab CAP cov khoom. Nws tuaj yeem tsim tau 4000 tons ntawm cellulose acetate propionate (CAP) thiab cellulose acetate butyrate (CAB) txhua xyoo, thiab siv dav hauv kev ua cov khoom xa tawm xws li coatings, zaub mov ntim, menyuam yaus cov khoom ua si, cov ntaub ntawv kho mob, thiab lwm yam.
