Cov Khoom Siv
Cov tshuaj pleev ib ce thiab cov khoom saib xyuas tus kheej 1,3-butylene glycol yog siv tau ua tus nyiam thiab hnyav. Vim nws cov khoom siv hygroscopicity zoo thiab ruaj khov, nws yog qhov kev saib xyuas cov tawv nqaij, cov khoom ua kom plaub hau thiab cov tshuaj pleev plaub hau los pab khaws cov tawv nqaij noo noo. Cov kev ua haujlwm ntawm cov tshuaj thiab cov tshuaj hauv kev lag luam kws tshuaj, 1,3-Butanediol yog siv los ntawm kev tshuaj yeeb thiab stabilizations, uas nws tuaj yeem txhim kho cov solubility thiab nqus tshuaj. Kev muaj kuab tshuaj lom 1,3-butanediol yog cov kuab tshuaj organic zoo li qub xws li cov tshuaj pleev xim ua xws li cov tshuaj pleev xim, cov tshuaj ntxuav thiab tuaj yeem yaj ntau cov organic sib txuas. Cov zaub mov muaj ntxiv rau qee cov zaub mov, 1,3-Butanol yog siv ua kev nyiam thiab saj cov khoom noj, tab sis tus nqi siv yuav tsum ua raws cov qauv kev nyab xeeb. Tshuaj lom neeg cov ntaub ntawv tso cai 99% min 1,3-Butanediol yog ib qho tseem ceeb hauv kev sib xyaw ua ke xws li polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyester thiab polyourethane.
