I ka ʻimi ʻana i ka honua o nā kemika, hoʻokahi pūhui i kū i waho no kāna versatility a me ka hoʻohana ʻana i nā ʻoihana.tetraethyl silicate. ʻOiai ʻano paʻakikī paha kāna ʻano hana kemika, ʻo ka hoʻomaopopo ʻana he kī ia e mahalo ai i ke ʻano o ka hoʻoulu ʻana o kēia pūhui i nā hopena kemika koʻikoʻi ma nā ʻano like ʻole, mai ka uila a hiki i nā lāʻau lapaʻau. Ma kēia ʻatikala, e wāwahi mākou i kaʻO ka hoʻohālikelike tetraethyl silicatea e ʻimi i ke ʻano o kona ʻano molekala e hoʻoikaika ai i kāna ʻano ma nā noi ʻoihana.

He aha ka Tetraethyl Silicate (TEOS)?

ʻO Tetraethyl silicate, i ʻike nui ʻiaTEOS, he hui organosilicon me kakemika Si(OC2H5)4. Aia kēia pūhui i kahiʻātoma kilika (Si)paa i ehanā hui ethoxy (–OC2H5), hana ia amolekele tetrahedral. I ka hydrolyzed, puka ka TEOSsilika—he mea nui i hoʻohana ʻia i ka hana ʻana i nā ʻāpana uila, nā uhi, a me nā noi ʻē aʻe.

Ka hoomaopopo ana i konaʻano kimekinihiki iā mākou ke mahalo i ke kumutetraethyl silicatehe mea waiwai nui ia ma nā ʻoihana he nui.

E wawahi ana i ka Formula Tetraethyl Silicate

E hoʻomaopopo i ke koʻikoʻi otetraethyl silicate (Si(OC2H5)4), e nānā mua kākou i nā ʻāpana pākahi o kānaʻano molekala:

•ʻAtoma Silika (Si):He kuleana koʻikoʻi ka ʻātoma waena o ka molekala, ka silikoni i ka hana ʻana i nā paʻa paʻa me ka oxygen a me nā ʻātoma kalapona.

•Nā Pūʻulu Ethoxy (–OC2H5):Hana ʻia kēlā me kēia o nā hui ethoxy ʻehā me kahi ʻātoma oxygen i hoʻopaʻa ʻia i kahi hui ethyl (C2H5). ʻO kēia ka mea e hoʻoikaika nui ai ʻo TEOS a hiki ke hana i nā hopena kemika nui e like mehydrolysisacondensation.

Hāʻawi kēia mau paʻa iā TEOS i nā waiwai kūʻokoʻa, e hoʻohana nui ai i ka hana ʻananā mea hana silicaa me nā pūhui holomua ʻē aʻe.

Pehea ka hoʻololi ʻana o ke ʻano ʻo Tetraethyl Silicate i nā hopena kemika

ʻO kaʻO ka hoʻohālikelike tetraethyl silicatehe mea nui ia no ka hoʻomaopopo ʻana i kāna ʻano hana i loko o nā hopena kemika. ʻO ka mea nui loa, ke hana nei ʻo TEOS i kahi kaʻina i kapa ʻia ʻohydrolysis, kahi e hana ai nā hui ethoxy me ka wai, e alakaʻi ana i ka hoʻokumu ʻana osilikaa me ka ethanol. He mea nui kēia pane i ka hana ʻana okiʻiʻoniʻoni ʻili silikaa me nā mea ʻē aʻenā mea hana kilika, he mea koʻikoʻi i nā mea uila, nā uhi, a me nā lāʻau lapaʻau.

Hydrolysis o Tetraethyl Silicate

Ke hoʻopili ʻo TEOS me ka wai, ua hoʻololi ʻia nā hui ethoxy e nā hui hydroxyl, e alakaʻi ana i ka hoʻokumu ʻana okinikini hydroxide(Si–OH). Hoʻopuka kēia kaʻina hanaethanolma ke ʻano he huahana ʻole. ʻO ke kaʻina hana hydrolysis e hoʻomalu nui ʻia i nā ʻoihana ʻoihana e hōʻoia i ka hoʻokumu ʻana o ke ʻano kiʻekiʻesilikamea waiwai.

ʻO ka hoʻohuihui o Tetraethyl Silicate

Ma hope o ka hydrolysis, kahui hydroxylhiki ke launa pū me nā ʻātoma silika ʻē aʻe, e alakaʻi ana icondensationnā pane. Hoʻokumu kēia ʻanuʻusilika-oxygen-silikona(Si–O–Si) paʻa, ka hopena i ka hana ʻana i kahi ʻano pūnaewele i kapa ʻia ʻosilika. ʻO ka hiki o TEOS ke hana i kēia mau paʻa e hiki ai ke kōkua i ka hoʻokumu ʻana onā pūnaewele silica ikaika a paʻa.

Nā noi o Tetraethyl Silicate a me kāna ʻano hoʻohālikelike

ʻO kaʻO ka hoʻohālikelike tetraethyl silicatea ʻo kāna hana ʻana e hoʻolilo iā TEOS i mea koʻikoʻi i kekahi mau ʻoihana:

1. Elele a me Semiconductor Manufacturing

ʻO TEOS kahi mea nui i ka hana ʻana osilika dioxidenā kiʻiʻoniʻoni i hoʻohana ʻia i ka ʻoihana uila. Ma ka hoomaopopo ana i konaʻano kimekini, hiki i nā mea hana ke hoʻomalu pono i kamaikaʻiamānoanoao kēia mau kiʻiʻoniʻoni, hoʻomaikaʻi i ka hana omicrochipsanā mea hana semiconductor.

2. Nā Pepa a me nā Pena

I kaʻoihana uhi, Hoʻohana ʻia ʻo TEOS no ka hana ʻana i nā ʻāpana pale, pale ʻole no nā ʻano like ʻole. ʻO ka hoʻokumu ʻana o ka silica ma o TEOS hydrolysis e hōʻoia i ka paʻa ʻana o nā pale a lōʻihi.

3. ʻO nā lāʻau lapaʻau

ʻO kaʻO ka hoʻohālikelike tetraethyl silicatemea nui no hoi ma kaʻoihana lāʻau lapaʻauno ka hana ananā mea kōkua silica, he mea nui i ka hookumu ana onā papa a me nā capsules. Kōkua ʻo TEOS i ka hoʻomaikaʻi ʻana i kakūpaʻa, bioavailability, auku hoopauo na mea hooikaika i na laau lapaau.

No ke aha he mea nui ka hoʻomaopopo ʻana i ka Formula Tetraethyl Silicate

ʻO ke ʻano kemika otetraethyl silicateʻoi aku ka nui ma mua o ka hōʻike wale ʻana o ka hui. Hāʻawi ia i ka ʻike pehea e launa pū ai ʻo TEOS me nā kemika ʻē aʻe, pehea e hana aisilikapūnaewele, a no ke kumu he waiwai nui ia i nā noi ʻoihana. Inā paha i lokomea uila, nā uhi, a i ʻolelāʻau lapaʻau, ʻO ka hoʻolālā kūʻokoʻa o TEOS hiki iā ia ke lawelawe ma keʻano he hale kūkulu hale no nā mea me nā waiwai kūikawā.

At ʻO Zhangjiagang Fortune Chemical Co., Ltd., ua kūpaʻa mākou i ka hoʻolako ʻana i ka maikaʻi kiʻekiʻetetraethyl silicateno nā ʻoihana ʻenehana like ʻole. Ma ka hoomaopopo ana i kaʻO ka hoʻohālikelike tetraethyl silicatea me kāna hana kemika, hiki iā ʻoe ke wehe i ka mana piha o kēia pūhui ikaika i kāu mau huahana a me nā kaʻina hana.
