Hydrophobic Fumed Silica
Hoʻolauna Huahana
Fumed silica, a i ʻolesilika pyrogenic, colloidal silicon dioxide, he pauda anorganic ke'oke'o amorphous nona ka ili kiko'ī kiko'ī ki'eki'e, ka nui o ka mea nui nano-scale a me ke ki'eki'e (ma waena o nā huahana silica) o nā hui silanol ili. Hiki ke hoʻololi kemika i nā waiwai o ka silica fumed ma ka hoʻololi 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 ma ke ʻano he mea koʻikoʻi i nā ʻoihana he nui e like me ka silicone rubber, pena a me nā ʻoihana plastics.
Nā Waiwai Huahana
1. Hoʻohana ʻia i loko o nā wai polar paʻakikī, e like me ka epoxy resin, polyurethane, vinyl resin, me ka mānoanoa maikaʻi a me ka hopena thixotropic;
2. Hoʻohana ʻia e like me ka mānoanoa, thixotropic agent, anti-settling a anti-sagging i loko o ka humuhumu a me ke kaula kaula;
3. Anti-settling agent no ka hoʻopiha piha piha;
4. Hoʻohana ʻia i ka toner no ka wehe ʻana a me ka anti-caking;
5. Hoʻohana ʻia i nā pena e hoʻomaikaʻi i ka paʻa o ka mālama ʻana;
6. ʻO ka hopena defoaming maikaʻi loa i ka defoamer;
Nā Kūlana Huahana
| Helu | Mea nānā | Unite | Kūlana nānā |
| 1 | Maʻiʻo silika | m/m% | ≥99.8 |
| 2 | ʻāpana ili kiko | m2/g | 80 – 120 |
| 3 | poho ma ka maloo 105 ℃ | m/m% | ≤1.5 |
| 4 | poho ma ka ignition1000 ℃ | m/m% | ≤2.5 |
| 5 | PH o ka hoʻomaha (4%) | 4.5 – 7.0 | |
| 6 | ʻIke ʻia ka mānoanoa | g/l | 30 – 60 |
| 7 | ʻAno kalapona | m/m% | 3.5 – 5.5 |
Hoʻohana Huahana
Hoʻohana nui ʻia i loko o nā uhi, adhesives, sealants, photocopying toner, epoxy a me vinyl resins a me gelcoat resins, cable glue, seamstresses, defoamers 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 pallet
3. Pono e mālama ʻia i loko o ka ʻeke kumu ma kahi maloʻo
4. Pale ʻia mai ka mea hikiwawe
