Hydrophilic Fumed Silica
Hoʻolauna Huahana
ʻO ka silica fumed, a i ʻole pyrogenic silica, colloidal silicon dioxide, he amorphous keʻokeʻo inorganic pauda nona ka ʻāpana kikoʻī kikoʻī kiʻekiʻe, ka nui o nā mea nui nano-scale a me kahi kiʻekiʻe (ma waena o nā huahana silica) ka ʻike o nā hui silanol ili. Hiki ke hoʻololi kemika i nā waiwai o ka silica fumed ma ka hoʻopili ʻana me kēia mau hui silanol.
Hiki ke hoʻokaʻawale ʻia ka silica fumed pāʻoihana i ʻelua pūʻulu: hydrophilic fumed silica a me hydrophobic fumed silica. hoʻohana nui ʻia ʻo ia ma ke ʻano he mea koʻikoʻi i nā ʻoihana he nui e like me ka silicone rubber, pena a me nā ʻoihana plastics.
Nā ʻano nui
1, hoʻopuehu maikaʻi, maikaʻi anti-sinking a adsorption.
2, I loko o ka silicone rubber: hoʻoikaika kiʻekiʻe, kiʻekiʻe waimaka kūpaʻa, maikaʻi abrasion kū'ē, maikaʻi kaʻikeʻike.
3, i ka pena: anti-sagging, anti-settling, hoʻomaikaʻi i ka paʻa o ka puaʻa, hoʻomaikaʻi i ka lūlū puaʻa, hoʻomaikaʻi i ka adhesion kiʻiʻoniʻoni, anti-corrosion, wai wai, pale i ka bubbling, kōkua i ke kahe, hoʻonui i ka mana rheological.
4, E pili ana i kēlā me kēia papa pena (adhesive, coating, ink) e hoʻomaikaʻi i ka paʻa o ka puaʻa, hoʻomaikaʻi i ka hoʻopuehu puaʻa, hoʻomaikaʻi i ka hoʻopili ʻana i ke kiʻiʻoniʻoni, anti-corrosion, wai ʻole, anti-settling, anti-bubbling, ʻoi aku no ka silicone rubber reinforcing, adhesive thixotropic agent, anti-settling agent no ka ʻōnaehana kala.
5, no ka ʻōnaehana wai hiki ke loaʻa ka mānoanoa, ka mana rheology, hoʻokuʻu, anti-sagging a me nā kuleana ʻē aʻe.
6, No ka ʻōnaehana paʻa hiki ke hoʻomaikaʻi i ka hoʻomaikaʻi ʻana, pale-pale a pēlā aku.
7, No ka ʻōnaehana pauka hiki ke hoʻomaikaʻi i ke kahe manuahi a pale i ka agglomeration a me nā hopena ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha ikaika no ka lāʻau kūlohelohe a me ka synthetic, lāʻau lapaʻau a me nā mea hoʻonaninani.

Hoʻohana Huahana
Hoʻohana nui ʻia i loko o ka silicone rubber (HTV, RTV), nā pena, nā uhi, nā inika, nā uila, ka hana pepa, ka momona, ka fiber-optic cable grease, resins, resins, glass fiber reinforced plastic, glass adhesive (sealant), adhesives, defoamers, solubilizers, plastics, ceramics a me nā ʻoihana ʻē aʻe.
Puke a me ka waiho ʻana
1. Hoʻopili ʻia i loko o ka pepa kraft papa he nui
2.10kg mau ʻeke ma ka pā
3. Pono e mālama ʻia i loko o ka ʻeke kumu ma kahi maloʻo
4. Pale ʻia mai ka mea hikiwawe
