Qhov nce nyob rau hauv cov ntsiab lus ntawm butyryl pawg neeg tau txais kev txo qis hauv qhov ntom ntom thiab nthuav dav ntawm cov kev sib cais. Muaj 12% mus rau 15% acetyl pawg thiab 26% mus rau 29% butyryl pawg. Pob tshab los yog opaque granular cov ntaub ntawv, nrog kev ntxhib los mos thiab zoo txias kuj. CAB tuaj yeem siv los ua cov khoom siv raw rau kev npaj cov yeeb yaj kiab substrates, aerial photography substrates, nyias zaj duab xis, thiab lwm yam. Nws kuj tseem siv tau los ua cov khoom siv raw rau kev xa cov kav dej, cov cuab yeej tuav, cables, cov paib sab nraud, cov thawv ntim khoom, thiab lwm yam. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov txheej txheej txheej, cov txheej txheem rwb thaiv tsev, huab cua resistant high-end coatings, thiab cov khoom siv fiber ntau.
Cov yam ntxwv ntawm cellulose acetate butyrate
Cellulose acetate butyrate muaj qee yam tshwj xeeb uas ua rau nws pom dav hauv cov ntawv thov. Ua ntej, nws muaj qhov zoo solubility thiab adsorbability, thiab tuaj yeem sib xyaw nrog lwm cov ntaub ntawv kom ua tiav kev ua haujlwm zoo. Thib ob, cellulose acetate butyrate muaj cov dej noo zoo thiab cov khoom siv moisturizing, uas tuaj yeem tswj cov av noo thiab ruaj khov ntawm cov khoom. Tsis tas li ntawd, nws kuj muaj biocompatibility zoo thiab yuav tsis muaj teebmeem 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 tag nrho nws cov kev ua tau zoo. Ua ntej, cellulose acetate butyrate yuav tsum tau qhuav ua ntej siv los txhim kho nws cov solubility thiab stability. Qhov thib ob, thaum lub sij hawm ua, kub thiab acidic tej yam kev mob yuav tsum tau zam kom tsis txhob decomposition thiab degradation ntawm cellulose. Tsis tas li ntawd, cov kev cai thiab cov cai yuav tsum tau ua raws li thaum siv los xyuas kom meej qhov ua tau zoo thiab kev nyab xeeb ntawm cov ntaub ntawv.
Yuav ua li cas txiav txim qhov zoo ntawm cellulose acetate butyrate
Qhov zoo ntawm cellulose acetate butyrate tuaj yeem txiav txim los ntawm cov hauv qab no. Ua ntej, nws tuaj yeem txiav txim siab los ntawm kev tshuaj xyuas seb nws cov tsos yog qhuav thiab tsis muaj impurities pom tseeb. Thib ob, nws cov solubility thiab kev ruaj ntseg tuaj yeem kuaj tau, thiab cov khoom zoo ntawm cellulose acetate butyrate yuav tsum muaj cov solubility zoo thiab thermal stability. Tsis tas li ntawd, nws tseem tuaj yeem xa mus rau lub koob npe nrov thiab ntawv pov thawj ntawm cov chaw muag khoom thiab xaiv cov neeg muag khoom muaj npe nrov thiab tsim nyog los xyuas kom meej cov khoom zoo thiab kev ntseeg siab.
Unilong Kev Lag Luam tau cog lus rau kev tshawb fawb ntawm cellulose esters thiab yog lub ntiaj teb muab kev pabcuam 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 tau siv dav hauv kev ua cov khoom xa tawm xws li txheej txheej, ntim khoom noj, cov menyuam yaus cov khoom ua si, khoom siv kho mob, thiab lwm yam.
