Propionic Acid los ntawm Shandong Pulisi Chemical Co., Ltd.
Shandong Pulisi Chemical Co., Ltd. muab cov tshuaj propionic acid zoo (CAS 79-09-4) uas tsim los rau cov neeg yuav khoom thoob ntiaj teb hauv cov khoom siv khaws cia zaub mov, cov khoom siv ntxiv rau tsiaj txhu, cov tshuaj tua kab mob, thiab cov khoom siv ua kom cov khoom noj muaj txiaj ntsig zoo. Peb cov tshuaj propionic acid yog tsim los ntawm kev tswj hwm zoo, ua tau raws li cov qauv kev ntshiab hauv tebchaws thiab thoob ntiaj teb, suav nrog ≥99.5% concentration rau kev siv hauv kev lag luam ncaj qha thiab cov qauv tsim tshwj xeeb kom haum rau cov neeg siv khoom siv.
Ua ib qho tseem ceeb ntawm cov organic acid intermediate, peb cov propionic acid yog siv dav hauv kev tsim cov calcium propionate thiab sodium propionate—cov tshuaj preservatives tseem ceeb rau cov khoom ci thiab cov nplej—thaum nws cov esters ua haujlwm ua cov kuab tshuaj tshwj xeeb hauv cov xim thiab cov tshuaj tsw qab. Nws kuj ua haujlwm ua cov khoom siv silage zoo los tiv thaiv kev loj hlob ntawm pwm hauv cov khoom noj tsiaj, txhawb nqa kev lag luam ua liaj ua teb nrog kev muab khoom siv txhim khu kev qha thiab sib xws.
Ntim raws li cov qauv kev xa khoom thoob ntiaj teb, peb cov propionic acid muaj nyob rau hauv cov nruas txhuas lossis cov thoob hlau uas muaj hlua kom tswj tau cov khoom ruaj khov thiab kev nyab xeeb thaum lub sijhawm thauj mus los. Txhawb nqa los ntawm ntau tshaj ob xyoo caum ntawm kev paub txog kev xa khoom tawm, peb muab cov xaj xaj yooj ywm, kev xa khoom raws sijhawm, thiab kev txhawb nqa kev txawj ntse kom tau raws li ntau yam kev xav tau ntawm peb cov neeg koom tes thoob ntiaj teb.
