Pob:200kg / yas nruas (los yog zinc plating hlau nruas), los yog raws li tus neeg yuav tsum tau muaj
Cia txias:Khaws rau hauv cov thawv ntim khoom ntawm qhov chaw txias thiab qhuav;Tiv thaiv los ntawm lub teeb thiab noo noo
Hexamethylphosphoramide (HMPA) (CAS: 680-31-9) yog soluble hauv polar thiab non-polar solvents.Nws kuj yog miscible nrog cov yas siv feem ntau xws li dioctyl phthalate, dioctyl sebacate, thiab triphenyl phosphite hauv ib qho kev faib ua feem.Tsis txhob kov cov tawv nqaij.Nws cov ntim yuav tsum tau muab kaw kom nruj kom tiv thaiv kom tsis txhob tawm thiab nqus dej kom tsis zoo Hexamethylphosphoramide yog lub teeb stabilizer ntawm PVC, ua kom muaj kev tiv thaiv kev laus zoo ntawm cov khoom sab nraum zoov nrog huab cua tiv thaiv zoo, yog li paub tias yog tus neeg saib xyuas huab cua zoo ntawm PVC. .Ntxiv ntawm cov khoom no rau PVC zaj duab xis tuaj yeem txhim kho ob qho tib si huab cua tiv thaiv thiab txias ua haujlwm nrog rau kev txo qhov kub ntawm 10 ℃.1. Nws tuaj yeem siv los ua tus neeg saib xyuas kev tiv thaiv zoo ntawm PVC thiab lwm yam khoom siv chlorine-muaj cov khoom siv thiab cov txheej txheem.2. Cov khoom yog cov huab cua hnyav ntawm polyvinyl chloride thiab zoo heev polar solvent, muaj qhov cuam tshuam rau qhov kub thiab txias tsis kam thiab kev laus ua haujlwm ntawm cov yeeb yaj kiab ua liaj ua teb;nws yog ib tug multi-functional high-boiling polar solvent uas yog aprotic.Nws tuaj yeem siv los ua cov kuab tshuaj ntawm polymer synthesis nrog cov nyhuv tshwj xeeb ntawm kev sib txuas ntawm polyphenylene sulfide thiab aromatic polyamide thiab lwm yam.Cov khoom no, raws li cov co-catalyst ntawm propylene polymerization catalyst, thaum nkag mus rau ethylene propylene roj hmab, tuaj yeem txhim kho lub foob pob hluav taws thiab roj tsis kam ntawm qhov kawg.Hexamethylphosphoramide kuj tseem siv tau los ua cov roj chromatographic fixative, ultraviolet inhibitor, foob pob hluav taws roj additives rau txo qis qhov chaw khov thiab tshuaj tua kab mob.3. Nws yog qhov zoo uas tsis yog-proton hnyav;raws li fixative ntawm cov roj chromatography (siab tshaj plaws kev siv kub: 35 ° C nrog methanol ua cov kuab tshuaj);siv rau kev sib cais thiab kev tsom xam ntawm hydrocarbons;rau kev sib cais ntawm alkanes, alkenes thiab alkynes;accelerator ntawm lub tso suab tshwj xeeb cov tshuaj tiv thaiv;Ultraviolet inhibitor ntawm PVC.
