Tetraethyl silicate (TEOS)he mea hoʻohui kemika e pāʻani ana i ka hana koʻikoʻi ma nā ʻoihana like ʻole, mai ka uila a hiki i nā lāʻau lapaʻau. ʻOiai ʻaʻole ia he inoa ʻohana, hoʻomaopopo i kānaʻano molekalaHe mea nui ia i ka mahalo ʻana i kāna versatility a me nā noi. Ma kēia ʻatikala, e luʻu mākou i kaʻo ka hoʻolālā tetraethyl silicate, pehea i hoʻokumu ʻia ai, a me ke koʻikoʻi e paʻa ana ma nā ʻoihana lehulehu. E ʻimi kākou i ke kumu i waiwai nui ai kēia pūhui.

He aha ka Tetraethyl Silicate?

Ma mua o ko kākou komo ʻana i kona ʻano, e wehewehe mua kākou i ka meatetraethyl silicateʻo ia. ʻO TEOS kahi hui organosilicon me ke ʻano kemikaSi(OC2H5)4. Ua ʻike ʻia ʻo ia ʻotetraethyl orthosilicatea ua hoʻohana mua ʻia ma ke ʻano he precursor i ka hana ʻana i nā mea hana silica, me nā kaʻina hana sol-gel.

Ua hoʻohana ʻia kēia wai waihoʻoluʻu a hiki ke hoʻohana ʻia no nā makahiki he nui, ʻoi loa i ka hana ʻanasilika dioxide, he mea nui ia i nā mea uila, nā uhi, a me ke ʻano he catalyst i ke kaʻina hana o nā huahana like ʻole.

Ka wawahi ana i ke kukulu ana o Tetraethyl Silicate

No ka hoʻomaopopo maoli ʻana peheahana ka tetraethyl silicate, he mea nui e kālailai i konaʻano molekala. Aia ka mole i ke kikowaenaʻātoma kilika (Si), i hoʻopaʻa ʻia i nā hui ethoxy ʻehā(–OCH2CH3). Hoʻopili ʻia kēia mau hui ethoxy i ka ʻātoma silika mapaa hookahi, a loaʻa i kēlā me kēia hui ethoxy kahiʻātoma oxygenpili i kahihui ethyl (C2H5).

I ke kumu,tetraethyl silicatehe molekele tetrahedral me kaʻātoma silikae noho ana ma waenakonu o ka hale, i hoʻopuni ʻia e ʻehānā hui ethoxy. ʻAʻole paʻa wale kēia hoʻonohonoho akā hiki nō hoʻi iā TEOS ke lilo i pūhui reactive nui, hiki ke hanahydrolysis a me nā hopena condensatione hananā pūnaewele silica.

ʻO ke kuleana o Tetraethyl Silicate i ka ʻoihana

ʻO kaʻo ka hoʻolālā tetraethyl silicatehe hopena koʻikoʻi kona pono ma nā ʻāpana like ʻole. E ʻimi kākou i kekahi mau ʻoihana e pōmaikaʻi ana mai TEOS:

1. ʻOihana Electronic a me Semiconductor

I kaʻoihana uila, Hoʻohana mua ʻia ʻo TEOS e hananā kiʻiʻoniʻoni lahilahima nā wafer semiconductor. Pono kēia mau kiʻiʻoniʻoni no ka insulating circuit a me ka pale ʻana i nā ʻāpana palupalu. I ka wā e hele ai ʻo TEOShydrolysis a me ka condensation, hana ia i kahi ʻāpana lahilahi a like ʻole osilikama ka substrate, he hana koʻikoʻi ia i lokohana kaapuni hoʻohuihui (IC)..

2. Nā Pepa a me nā Pena

ʻO kaʻo ka hoʻolālā tetraethyl silicateHe kuleana nō hoʻi i ka hana ʻana i nā uhi a me nā pena. Ke hoʻohana ʻia ʻo TEOS manā hana sol-gel, kōkua ia e hana i kahi lōʻihi,pale-paleka uhi ʻana. Ua kaulana kēia kaʻina hana makaʻa kaʻa, nā lens optical, apale paleno nā metala.

3. ʻO nā lāʻau lapaʻau

I kaʻoihana lāʻau lapaʻau, hoʻohana ʻia ka tetraethyl silicate i kekahi manawa i ka hana ʻana onā mea kōkua silicano nā papa a me nā capsules. He kuleana koʻikoʻi kēia mau excipientshana lāʻau, hoonui analawe lāʻauabioavailability. Hiki i ka silica mai TEOS ke hoʻomaikaʻi i ka solubility a me ka paʻa o kekahi mau lāʻau lapaʻau, e ʻoi aku ka maikaʻi no nā maʻi.

No ke aha he mea koʻikoʻi ke ʻano o Tetraethyl Silicate?

ʻO kaʻo ka hoʻolālā tetraethyl silicateʻO ia ke kī i kāna versatility a me ka hoʻohana nui ʻana i kēia mau ʻoihana. ʻO ka molehoʻonohonoho tetrahedralhiki iā ia ke hoʻopaʻa maʻalahi me nā mea ʻē aʻe, e hana i nā mea paʻa a paʻa. ʻO kona hiki ke hana me ka wai, alakaʻi ihydrolysis, a laila e hananā hopena condensation, lilo ia i mea mua no ka hana ʻanasilika—he mea i ikeia no konaikaika, kū'ē kemika, a me nā waiwai insulating.

ʻO kanā hui ethoxyma ka ʻātoma silika hoʻi e hoʻoheheʻe loa ʻia ka TEOS i lokonā mea hoʻoheheʻe organik, hoʻonui i kona hiki ke hoʻohanaʻia i nāʻano hanaʻoihana.

ʻO ka wā e hiki mai ana o Tetraethyl Silicate

Ke hoʻomau nei nā ʻoihana i ka hoʻoikaika ʻana i nā mea ʻoi aku ka maikaʻi, ka lōʻihi, a me ka hoʻomau, ʻo ke koʻikoʻi o ka tetraethyl silicate e hoʻonohonoho wale ʻia e ulu. Me ka piʻi ʻana o ka noi nonā mea uila uila ʻoi aku ka ikaika, nā uhi kiʻekiʻe, amea biocompatible, E noho mau paha ʻo TEOS ma ke alo o ka ʻenehana hou.

Konamaʻalahiahoʻopāpāhōʻoia i kēlātetraethyl silicatee hoʻomau i ka hana koʻikoʻi i ka hoʻomohala ʻana i nā huahana a me nā ʻenehana hou.

E hoʻohana i ka mana o Tetraethyl Silicate no kāu ʻoihana

Inā ʻoe e hana nei i nā mea uila, nā uhi, a i ʻole nā ​​lāʻau lapaʻau, e hoʻomaopopo i kaʻo ka hoʻolālā tetraethyl silicatea he mea koʻikoʻi kona mau molekala no ka hoʻonui ʻana i kona hiki. Me kona mana kū hoʻokahi e hananā mea hana silicame nā waiwai koʻikoʻi, noho mau ʻo TEOS i mea koʻikoʻi ma waena o nā ʻoihana he nui.

At ʻO Zhangjiagang Fortune Chemical Co., Ltd., Hoʻolaha mākou i ka hāʻawi ʻana i ka tetraethyl silicate kiʻekiʻe no ka nui o nā noi. Inā ʻoe e ʻimi e hoʻonui i ka hana o kāu huahana,e hoʻokaʻaʻike mai iā mākou i kēia lāe aʻo pehea e hiki ai iā TEOS ke kōkua i kāu ʻoihana e holomua!
