High-Purity Neopentyl Glycol rau Cov Ntawv Siv Hauv Kev Lag Luam
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam ntawm cov tshuaj pleev xim thiab cov resins, Neopentyl Glycol yog ib qho khoom siv tseem ceeb rau kev tsim cov roj polyester uas muaj roj saturated, cov roj polyester uas tsis muaj roj, cov roj polyester polyols, thiab cov roj alkyd. Cov roj no siv dav hauv kev lag luam tsheb, khoom siv hauv tsev, thiab cov khoom siv kho kom zoo nkauj, tshwj xeeb tshaj yog hauv kev lag luam ntawm cov tshuaj pleev xim hmoov, qhov twg daim ntawv thov thiab kev txhim kho ntawm Neopentyl Glycol yog qhov tseem ceeb. Piv txwv li, xyoo 2013, kwv yees li 72% ntawm Neopentyl Glycol tau siv los tsim cov roj polyester rau cov tshuaj pleev xim hmoov, uas tam sim no tau mus txog 89%. Hauv kev lag luam ntawm polyurethanes, Neopentyl Glycol yog siv los tsim cov polyester polyols, uas feem ntau yog siv rau cov polyurethanes uas tsis yog ua npuas ncauj. Polyurethanes uas muaj Neopentyl Glycol muaj kev ruaj khov hydrolytic zoo heev, qhov kub hloov iav qis, qhov chaw yaj qis, kev ruaj khov thermal thiab UV zoo, thiab kev tiv thaiv tshuaj lom neeg. Cov khoom no ua rau nws yog ib qho khoom siv tseem ceeb hauv kev tsim cov thermoplastic polyurethanes, polyurethane coatings, cast elastomers, thiab cov nplaum. Hauv kev ua cov yas thiab cov roj nplua nyeem, Neopentyl Glycol siv los ua cov yas, muab PVC ua haujlwm kub qis zoo heev, nrog rau kev hloov pauv qis thiab kev tsiv teb tsaws chaw. Tsis tas li ntawd, Neopentyl Glycol diester resins siv rau hauv kev tsim cov roj nplua nyeem zoo. Cov roj nplua nyeem no, ntxiv rau cov ntsiab lus khov qis, cov ntsuas viscosity siab, thiab cov ntsiab lus flash siab, kuj muaj kev ruaj khov thermal zoo heev. Hauv kev ua lag luam tshuaj, Neopentyl Glycol ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj intermediates. Piv txwv li, hauv kev tsim cov tshuaj tua kab mob, Neopentyl Glycol ua rau cov txiaj ntsig thiab kev ntshiab ntawm cov tshuaj tua kab mob ntau ntxiv los ntawm kev koom nrog kev tsim cov tshuaj intermediates tseem ceeb. Tsis tas li ntawd, Neopentyl Glycol kuj ua lub luag haujlwm tseem ceeb hauv kev tsim cov tshuaj tiv thaiv kab mob qog noj ntshav thiab cov tshuaj cardiovascular. Neopentyl Glycol kuj tseem siv tau ua cov kuab tshuaj zoo heev rau kev sib cais xaiv ntawm aromatic thiab cycloalkane hydrocarbons. Nws cov khoom siv yog siv rau hauv cov tshuaj tsw qab, tshuaj, cov nplaim taws retardants, aviation lubricants, plasticizers, inks, insulating cov ntaub ntawv, thiab lwm yam, thiab yog dav siv hauv coatings, tsheb, textiles, tshuaj tua kab, plastics, thiab roj av teb.
