ʻO ka Neopentyl Glycol Maʻemaʻe Kiʻekiʻe (ʻO ka Neopentyl Glycol maʻemaʻe kiʻekiʻe) no nā noi ʻoihana
Nā Kahua Noi Nui
Ma ke kahua o nā uhi a me nā resins, ʻo Neopentyl Glycol kahi mea maka koʻikoʻi no ka hana ʻana i nā resins polyester saturated, nā resins polyester unsaturated, polyester polyols, a me nā resins alkyd. Hoʻohana nui ʻia kēia mau resins i nā ʻoihana kaʻa, nā mea hana home, a me nā mea hoʻonaninani, ʻoi aku hoʻi ma ke kahua o nā uhi pauka, kahi i ʻike nui ʻia ai ka noi a me ka hoʻomohala ʻana o Neopentyl Glycol. No ka laʻana, i ka makahiki 2013, ma kahi o 72% o Neopentyl Glycol i hoʻohana ʻia e hana i nā resins polyester no nā uhi pauka, i hiki i kēia manawa i 89%. Ma ke kahua o polyurethanes, hoʻohana ʻia ʻo Neopentyl Glycol e hana i nā polyols polyester, i hoʻohana nui ʻia no nā polyurethanes non-foam. Loaʻa i nā Polyurethanes e loaʻa ana iā Neopentyl Glycol ke kūpaʻa hydrolytic maikaʻi loa, ka mahana hoʻololi aniani haʻahaʻa, ka wahi heheʻe haʻahaʻa, ka paʻa thermal a me UV maikaʻi, a me ke kūpaʻa kemika. ʻO kēia mau waiwai e lilo ia i mea maka koʻikoʻi i ka hana ʻana i nā polyurethanes thermoplastic, nā uhi polyurethane, nā elastomers i hoʻolei ʻia, a me nā mea hoʻopili. Ma ke kahua o nā plasticizers a me nā lubricants, hoʻohana ʻia ʻo Neopentyl Glycol e synthesize i nā plasticizers, e hāʻawi ana i ka PVC hana haʻahaʻa maikaʻi loa, a me ka volatility haʻahaʻa a me ka neʻe ʻana. Eia kekahi, hoʻohana ʻia nā resins diester Neopentyl Glycol i ka hana ʻana o nā lubricants synthetic kiʻekiʻe. ʻO kēia mau lubricants, me nā kiko hau haʻahaʻa, nā ʻōkuhi viscosity kiʻekiʻe, a me nā kiko flash kiʻekiʻe, loaʻa iā lākou ke kūpaʻa thermal maikaʻi loa. Ma ke kahua lāʻau lapaʻau, he kuleana koʻikoʻi ko Neopentyl Glycol i ka synthesis o nā intermediates lāʻau lapaʻau. No ka laʻana, i ka synthesis o nā antibiotics, hoʻonui nui ʻo Neopentyl Glycol i ka hua a me ka maʻemaʻe o nā antibiotics ma ke komo ʻana i ka synthesis o nā intermediates koʻikoʻi. Eia kekahi, he kuleana koʻikoʻi ko Neopentyl Glycol i ka synthesis o nā lāʻau anticancer a me nā lāʻau cardiovascular. Hiki ke hoʻohana ʻia ʻo Neopentyl Glycol ma ke ʻano he solvent maikaʻi loa no ka hoʻokaʻawale koho ʻana o nā hydrocarbons aromatic a me cycloalkane. Hoʻohana ʻia kāna mau mea i loaʻa i nā mea ʻala, nā lāʻau lapaʻau, nā mea hoʻomaha lapalapa, nā lubricants mokulele, nā plasticizers, nā ʻīnika, nā mea hoʻokaʻawale, a me nā mea ʻē aʻe, a hoʻohana nui ʻia i nā uhi ʻana, nā kaʻa, nā lole, nā pesticides, nā plastics, a me nā kahua ʻaila.

I ka hōʻuluʻulu manaʻo
I ka hōʻuluʻulu manaʻo, ʻo Neopentyl Glycol, me kona kūpaʻa kemika maikaʻi loa a me ka multifunctionality, he kuleana koʻikoʻi ia i nā uhi, nā resins, polyurethanes, plasticizers, lubricants, pharmaceuticals, a me nā ʻoihana ʻē aʻe. Me ka holomua mau o ka ʻenehana a me ka ulu mau ʻana o ke koi mākeke, e hoʻonui hou ʻia ka laulā o ka noi o Neopentyl Glycol, ʻoi aku hoʻi i nā ʻoihana e kū mai ana e like me ka ikehu hou, kemika ʻōmaʻomaʻo, a me nā mea kiʻekiʻe, e hoʻomau ka nui o kona koʻikoʻi.
