Mkhalidwe Wosungira:Sungani muzitsulo zosindikizidwa pamalo ozizira ndi owuma;Tetezani ku kuwala ndi chinyezi
Hexamethylphosphoramide (HMPA) (CAS: 680-31-9) imasungunuka muzitsulo za polar komanso zopanda polar.Imasokonekeranso ndi mapulasitiki omwe amagwiritsidwa ntchito kwambiri monga dioctyl phthalate, dioctyl sebacate, ndi triphenyl phosphite mwanjira iliyonse.Pewani kukhudzana ndi khungu.Zotengera zake ziyenera kusindikizidwa mwamphamvu kuti zipewe kutayikira komanso kuyamwa kwamadzi kuti zisawonongeke Hexamethylphosphoramide ndiye kuwala kokhazikika kwa PVC, kupangitsa kuti zinthu zakunja zisamakalamba zizikhala bwino ndi nyengo, chifukwa chake zimadziwika kuti ndizothandiza kwambiri polimbana ndi nyengo ya PVC. .Kuphatikiza kwa mankhwalawa ku filimu ya PVC kumatha kusintha kwambiri kukana kwanyengo komanso kukana kuzizira komanso kuchepetsa kutentha kwa 10 ℃.1. Ikhoza kugwiritsidwa ntchito ngati wothandizira bwino wotsutsa dzimbiri wa PVC ndi mitundu ina ya mankhwala a chlorine okhala ndi utomoni ndi zokutira.2. Chogulitsacho ndi chosungunulira nyengo ya polyvinyl chloride ndi zosungunulira zabwino kwambiri za polar, zomwe zimakhudza kwambiri kutentha kwapansi ndi kukana kukalamba kwa filimu yaulimi;ndi multifunctional high-boiling polar solvent kuti ndi aprotic.Iwo angagwiritsidwe ntchito monga solvents wa polima kaphatikizidwe wapadera kwambiri pa synthesis wa polyphenylene sulfide ndi onunkhira polyamide ndi zina zotero.Izi, monga co-chothandizira wa propylene polymerization chothandizira, pamene kuperekedwa kwa mphira ethylene propylene, akhoza kusintha mizinga ndi kukana mafuta wa yomalizayo.Hexamethylphosphoramide ingagwiritsidwenso ntchito ngati gasi chromatographic fixative, ultraviolet inhibitor, rocket fuel additives pofuna kuchepetsa kuzizira ndi mankhwala ophera tizilombo.3. Ndi othandiza sanali pulotoni zosungunulira;monga fixative wa gasi chromatography (kutentha kwambiri ntchito: 35 ° C ndi methanol monga zosungunulira);amagwiritsidwa ntchito kulekanitsa ndi kusanthula ma hydrocarbons;kwa kulekanitsa alkanes, alkenes ndi alkynes;accelerator ya stereo-specific reaction;Ultraviolet inhibitor ya PVC.
