Kev Siv
Nws yog siv ua cov khoom siv raw rau cov khoom siv tiv taus txias, cov resins thiab nylon, thiab lwm yam
Nws feem ntau yog siv ua cov khoom siv raw rau sebacate ester plasticizers thiab nylon molding resins, thiab kuj siv tau ua cov khoom siv raw rau cov roj nplua nyeem uas tiv taus kub siab. Nws cov khoom tseem ceeb ester yog methyl ester, isopropyl ester, butyl ester, octyl ester, nonyl ester thiab benzyl ester. Cov esters feem ntau siv yog dibutyl sebacate thiab dioctyl sebacate. Sebacic acid plasticizers tuaj yeem siv dav hauv polyvinyl chloride, alkyd resins, polyester resins thiab polyamide molding resins. Vim lawv tsis muaj tshuaj lom thiab tiv taus kub siab, lawv feem ntau siv rau hauv qee cov resins tshwj xeeb. Nylon molding resin tsim los ntawm sebacic acid muaj kev tawv siab thiab tsis nqus dej noo, thiab kuj tuaj yeem ua tiav rau ntau yam khoom tshwj xeeb. Sebacic acid kuj yog cov khoom ua kom mos rau roj hmab, surfactant, thiab cov khoom siv raw rau cov txheej thiab cov tshuaj tsw qab.
Cov roj chromatography tail suppressant, rau kev sib cais thiab kev tshuaj xyuas cov roj fatty acids, tuaj yeem siv rau kev nag thiab kev txiav txim siab ntau ntawm thorium, thiab tseem tuaj yeem cais thorium ntawm cerium thiab lwm yam khoom tsis tshua muaj. Cov yas ua kom yas, cov resins hluavtaws thiab cov fibers hluavtaws.
Siv rau kev sib cais thiab kev tshuaj xyuas cov roj fatty acids; Siv ua lub lim dej hauv cov roj chromatography; Siv ua lub tshuab yas, thiab lwm yam
Nws yog siv los ua ib qho analytical reagent, thiab lwm yam
Ntim thiab Xa Khoom
Ntim: 25kg, 200kg raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
