High-Purity Neopentyl Glycol (新戊二醇) yogwiritsidwa ntchito m'mafakitale
Minda Yaikulu Yogwiritsira Ntchito
Mu gawo la zokutira ndi ma resin, Neopentyl Glycol ndi chinthu chofunikira kwambiri popanga ma resin a polyester okhuta, ma resin a polyester osakhuta, ma polyol a polyester, ndi ma resin a alkyd. Ma resin awa amagwiritsidwa ntchito kwambiri m'mafakitale a magalimoto, zida zapakhomo, ndi zinthu zokongoletsera, makamaka m'munda wa zokutira za ufa, komwe kugwiritsa ntchito ndi kupanga kwa Neopentyl Glycol ndikodziwika kwambiri. Mwachitsanzo, mu 2013, pafupifupi 72% ya Neopentyl Glycol idagwiritsidwa ntchito popanga ma resin a polyester a zokutira za ufa, zomwe tsopano zafika pa 89%. Mu gawo la ma polyurethane, Neopentyl Glycol imagwiritsidwa ntchito popanga ma polyol a polyester, omwe amagwiritsidwa ntchito kwambiri pa ma polyurethanes osakhala a thovu. Ma polyurethanes okhala ndi Neopentyl Glycol ali ndi kukhazikika kwabwino kwa hydrolytic, kutentha kochepa kwa galasi, malo otsika osungunuka, kukhazikika kwabwino kwa kutentha ndi UV, komanso kukana mankhwala. Zinthu izi zimapangitsa kuti ikhale chinthu chofunikira kwambiri popanga ma polyurethanes a thermoplastic, zokutira za polyurethane, ma elastomers opangidwa, ndi zomatira. Mu gawo la mapulasitiki ndi mafuta odzola, Neopentyl Glycol imagwiritsidwa ntchito popanga mapulasitiki, zomwe zimapangitsa PVC kugwira ntchito bwino kwambiri kutentha pang'ono, komanso kusasinthasintha pang'ono komanso kusamuka. Kuphatikiza apo, ma resini a Neopentyl Glycol diester amagwiritsidwa ntchito popanga mafuta odzola apamwamba kwambiri. Mafuta awa, kuwonjezera pa malo oziziritsa otsika, ma index okwera kwambiri, ndi ma flash point okwera, alinso ndi kukhazikika kwabwino kwa kutentha. Mu gawo la mankhwala, Neopentyl Glycol imagwira ntchito yofunika kwambiri popanga mankhwala odzola. Mwachitsanzo, popanga maantibayotiki, Neopentyl Glycol imawonjezera kwambiri phindu ndi chiyero cha maantibayotiki mwa kutenga nawo mbali popanga ma key intermediates. Kuphatikiza apo, Neopentyl Glycol imagwiranso ntchito yofunika kwambiri popanga mankhwala oletsa khansa ndi mankhwala a mtima. Neopentyl Glycol ingagwiritsidwenso ntchito ngati chosungunulira chabwino kwambiri pakulekanitsa ma hydrocarbons a aromatic ndi cycloalkane. Zochokera ku izo zimagwiritsidwa ntchito mu zonunkhira, mankhwala osokoneza bongo, zoletsa moto, mafuta odzola ndege, mapulasitiki, inki, zinthu zotetezera kutentha, ndi zina zotero, ndipo zimagwiritsidwa ntchito kwambiri mu zophimba, magalimoto, nsalu, mankhwala ophera tizilombo, mapulasitiki, ndi minda ya mafuta.

Powombetsa mkota
Mwachidule, Neopentyl Glycol, yokhala ndi kukhazikika kwabwino kwa mankhwala komanso magwiridwe antchito ambiri, imagwira ntchito yofunika kwambiri pakuphimba, ma resin, ma polyurethane, ma plasticizer, mafuta odzola, mankhwala, ndi madera ena. Ndi kupita patsogolo kosalekeza kwa ukadaulo komanso kukula kosalekeza kwa kufunikira kwa msika, kuchuluka kwa momwe Neopentyl Glycol imagwiritsidwira ntchito kudzakulirakulira, makamaka m'magawo atsopano monga mphamvu zatsopano, chemistry yobiriwira, ndi zipangizo zapamwamba, kufunika kwake kudzapitirira kuwonjezeka.
