Trimethylolpropane (hōʻemi ʻia ʻo TMP)

ʻO Trimethylolpropane (TMP) he mea koʻikoʻi koʻikoʻi kemika maikaʻi me ka hoʻohana nui ʻana, e like me ka alkyd resins, polyurethanes, unsaturated resins, polyester resins, a me nā uhi. Hoʻohui ʻia, hoʻohana ʻia ʻo TMP i ka synthesis o nā lubricants aviation, paʻi ʻīnika, a lawelawe ma ke ʻano he textile auxiliary a me ka thermal stabilizer no nā resins polyvinyl chloride (PVC).

Ma ke ʻano he mea hoʻonui kaulahao i hoʻohana nui ʻia i ka ʻoihana resin, ʻo TMP kahi huahana koʻikoʻi e alakaʻi i ka hoʻonui ʻana i ka ʻoihana o ka ʻāpana polyols. Hāʻawi kona ʻano molekole kūʻokoʻa iā ia i kahi helu heheʻe haʻahaʻa a me nā hiʻohiʻona polyol-like glycerol. ʻAʻole hiki iā TMP ke hoʻololi wale i ka glycerol i ka synthesis o nā resins alkyd akā hoʻohui pū me nā polyols ʻē aʻe e like me neopentyl glycol a me pentaerythritol, e hoʻololi hou i nā ʻano o nā resins alkyd. Hoʻonui kēia versatility i ka hana a me ka hoʻololi ʻana o nā huahana i hoʻokumu ʻia i ka resin, e hoʻoikaika ana i ka hana koʻikoʻi o TMP i ka holomua ʻana i nā mea hou a me ka pono o ka noi ma nā ʻoihana.

ʻO nā resins Alkyd i hoʻomākaukau ʻia me ka hoʻohana ʻana i ka TMP hōʻike i ke kūpaʻa hydrolysis koʻikoʻi, ke kūpaʻa o ka oxidation, ke kūpaʻa alkali, a me ke kūpaʻa wela, e kūpono loa ia no ka hana ʻana i nā pena kaha alanui. Hoʻohana nui ʻia lākou i ka hana ʻana i nā pena topcoat no nā kaʻa, nā pahu hau, nā mīkini holoi, a me nā mea pono hale ʻē aʻe. Eia kekahi, hana koʻikoʻi ʻo TMP i nā kaʻina hana o nā surfactants, nā mea hoʻomaʻemaʻe, nā mea pahū, nā plasticizers, nā fiberglass-reinforced plastics, rosin esters, kiʻekiʻe-grade aviation lubricants, fiber processing agents, printing inks, a me polyurethane foams, e lawelawe ana ma ke ʻano he resin chain extender, textile auxiliary, a me ka thermal stabilizer no ka PVC.

Loaʻa nā derivatives o TMP i nā noi nui ma nā kahua he nui, e hana ana ma ke ʻano he crosslinking agents, curing agents, emulsifiers, release agents, and catalysts. Hoʻohana ʻia lākou i ka hana ʻana i nā electrodes membrane wai me ke koho kiʻekiʻe no nā ion sodium.

Hoʻohana mua ʻia ʻo TMP ma ke ʻano he mea maka no ka hana ʻana i nā mea hoʻōla PU, synthesizing i nā uhi UV, a me ka hana ʻana i nā resins alkyd kiʻekiʻe. Ma Kina, ʻoi aku ka nui o kāna ʻai ʻana ma luna o 70% o ka nui o ka hoʻohana ʻana o ka trimethylolpropane. Eia kekahi, he koʻikoʻi ko TMP i ka hana ʻana i nā resins polyester a me ka titanium dioxide.

Paʻa ʻo TMP i kahi kūlana koʻikoʻi i ka synthesis o nā resins alkyd kiʻekiʻe, i hoʻohana mau ʻia i nā pena kaʻa kaʻa a me nā mea hoʻōla kiʻi no nā pena a me nā inika. Ke hoʻomau nei ka maikaʻi o nā huahana i loko o nā ʻoihana kaʻa a me nā mea hana hale o Kina, ua piʻi nui ka noi no nā pale kiʻekiʻe. I ka manawa like, ʻoi aku ka ikaika o nā hoʻoponopono kaiapuni i alakaʻi i ka ulu mau i ka noi no nā mea hoʻoponopono kiʻi. No laila, manaʻo ʻia ka noi no TMP e ʻike i ka ulu nui i nā makahiki e hiki mai ana.
