Goobaha codsiga

Saliida lagama maarmaanka ah iyo waxyaabaha la isku qurxiyo

Propylene Glycol waa dareere ku habboon oo si ballaaran loogu isticmaalo saliidaha lagama maarmaanka ah iyo waxyaabaha la isku qurxiyo, lehna milmayn heer sare ah oo ku jira biyaha, saliidda, iyo hydrocarbons, oo leh ur khafiif ah, cuncun maqaarka hooseeya, iyo sunta hoose. Isticmaalkeeda cadarka ayaa ka badan kara 50%, halka alaabta kale ee quruxda, inta badan lagu xakameeyo 10% gudahood (miisaan ahaan). Codsiyada caadiga ah waxaa ka mid ah kareemka habaynta timaha, kareem qabow, dhaqidda jidhka, kareemka maqaarka, carfiyeyaasha, alaabta daryeelka wejiga iyo jidhka, qoyaanka, iyo dawooyinka dibnaha, iwm.

Wax soo saarka Resin waxaa loo isticmaalaa isku-dhafka xabagta polyester-ka ee aan saturated-ka ahayn iyo resins saturated, iyo resin-yada ka dhashay waxay leeyihiin dabacsanaan aad u fiican, iska caabin dildilaac ah, iska caabin cimilada, iyo iska caabbinta muddada dheer ee jaalaha.

Xalalka Warshadaha

Sida dareere loogu talagalay acetate cellulose, nitrocellulose, shellac varnish, iyo saliidda castor. Waxa kale oo loo isticmaali karaa diyaarinta balaastikada, fumigants, iyo saabuunta synthetic.

Habka wax soo saarka

Propylene Glycol waxaa inta badan soo saara falcelinta uumiga ee 1,2-epoxypropylene oo leh 1,2-propanediol oo hoos yimaada catalysis of 85% sulfuric acid. Dareen-celinta ka dib, waxaa lagu dhex milmay xal sodium hydroxide, la sifeeyay, ka dibna waxaa lagu shubaa nadiifinta faakuumka. Cadaadiska caadiga ah ka dib, distillate at 229-233 ℃ ayaa la ururiyaa si loo helo alaabta la dhammeeyey.

Intaa waxaa dheer, inta lagu jiro wax soo saarka fuuq-celinta ee propylene glycol laga bilaabo 1,2-epoxypropylene, propylene glycol waa mid ka mid ah alaabooyinka.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
