Neopentyl Glycol Parakore-Teitei mō ngā Taupānga Ahumahi
Ngā Āpure Tono Matua
I roto i te mara o ngā paninga me ngā kapia, he rauemi mata nui te Neopentyl Glycol mō te hanga kapia polyester kua kōtuitia, kapia polyester kāore i kōtuitia, kapia polyester polyols, me ngā kapia alkyd. He whānuitia te whakamahinga o ēnei kapia i roto i ngā ahumahi motuka, taputapu kāinga, me ngā rauemi whakapaipai, inā koa i roto i te mara o ngā paninga paura, te wāhi e tino kitea ana te whakamahinga me te whanaketanga o te Neopentyl Glycol. Hei tauira, i te tau 2013, tata ki te 72% o te Neopentyl Glycol i whakamahia hei hanga kapia polyester mō ngā paninga paura, kua eke ki te 89%. I roto i te mara o ngā polyurethanes, ka whakamahia te Neopentyl Glycol hei hanga kapia polyester polyols, e whakamahia ana mō ngā polyurethanes kore-huka. He tino pai te pumau o ngā polyurethanes kei roto ko te Neopentyl Glycol, he iti te pāmahana whakawhiti karāhe, he iti te ira rewa, he pai te pumau o te wera me te UV, me te ātete matū. Nā ēnei āhuatanga he rauemi mata nui i roto i te hanga polyurethanes thermoplastic, paninga polyurethane, elastomers maka, me ngā piripiri. I roto i te mara o ngā mea hanga kirihou me ngā hinu whakahinuhinu, ka whakamahia te Neopentyl Glycol hei hanga i ngā mea hanga kirihou, ka hoatu he mahi pai ki te PVC i te pāmahana iti, me te iti o te piki me te heke. Hei tāpiri, ka whakamahia ngā kapia Neopentyl Glycol diester ki te hanga hinu whakahinuhinu kounga teitei. Haunga ngā ira tio iti, ngā tohu matotoru teitei, me ngā ira mura teitei, he tino pai hoki te pumau o te wera o ēnei hinu whakahinuhinu. I roto i te mara rongoā, he mahi nui tā te Neopentyl Glycol i roto i te hanga o ngā takawaenga rongoā. Hei tauira, i roto i te hanga o ngā paturopi, ka whakanuia e te Neopentyl Glycol te hua me te parakore o ngā paturopi mā te whai wāhi ki te hanga o ngā takawaenga matua. Hei tāpiri, he mahi nui anō tā te Neopentyl Glycol i roto i te hanga o ngā rongoā ārai matepukupuku me ngā rongoā ngakau. Ka taea hoki te whakamahi i te Neopentyl Glycol hei whakarewa pai mō te wehenga whiriwhiri o ngā warowaihā kakara me te cycloalkane. Ka whakamahia ōna hua i roto i ngā kakara, i ngā rongoā, i ngā mea ārai mura, i ngā hinu whakahinuhinu rererangi, i ngā mea whakakirihou, i ngā waituhi, i ngā rauemi ārai, me ētahi atu, ā, e whakamahia whānuitia ana i roto i ngā paninga, i ngā motuka, i ngā kakahu, i ngā patupatu pepeke, i ngā kirihou, me ngā mara hinu.
