Silica Fumed Hydrophobic
Hoʻolauna Huahana
Silica i puhi ʻia, a i ʻolesilica pyrogenic, silicon dioxide koloidal, he pauka inorganic keʻokeʻo amorphous nona ka ʻili kikoʻī kiʻekiʻe, ka nui o nā ʻāpana mua nano-scale a me kahi kiʻekiʻe (ma waena o nā huahana silica) o nā hui silanol ʻili. Hiki ke hoʻololi kemika ʻia nā waiwai o ka silica fumed ma o ka hopena me kēia mau hui silanol.
Hiki ke hoʻokaʻawale ʻia ka silica fumed i loaʻa ma ke kālepa i ʻelua mau pūʻulu: silica fumed hydrophilic a me ka silica fumed hydrophobic. Hoʻohana nui ʻia ia ma ke ʻano he mea nui i nā ʻoihana he nui e like me ka silicone rubber, ka pena a me nā ʻoihana plastics.
Nā Waiwai Huahana
1. Hoʻohana ʻia i nā wai polar paʻakikī, e like me ka epoxy resin, polyurethane, vinyl resin, me ka maikaʻi o ka mānoanoa a me ka hopena thixotropic;
2. Hoʻohana ʻia e like me ka thickening, thixotropic agent, anti-settling a me anti-sagging i ka humuhumu a me ke kaula hoʻopili;
3. Mea hoʻopau i ka hoʻonohonoho ʻana no ka mea hoʻopihapiha kiʻekiʻe;
4. Hoʻohana ʻia i loko o ka toner no ka wehe ʻana a me ka anti-caking;
5. Hoʻohana ʻia i loko o nā pena e hoʻomaikaʻi i ke kūpaʻa mālama;
6. Ka hopena defoaming maikaʻi loa i ka defoamer;
Nā kikoʻī huahana
| Helu | Mea nānā | ʻĀpana | Kūlana nānā |
| 1 | ʻO ka nui o ka silica | m/m% | ≥99.8 |
| 2 | ʻĀpana ʻili kikoʻī | m2/g | 80 – 120 |
| 3 | pohō ma ka hoʻomaloʻo ʻana105℃ | m/m% | ≤1.5 |
| 4 | pohō ma ka hoʻā ʻana 1000℃ | m/m% | ≤2.5 |
| 5 | PH o ka hoʻokuʻu ʻana (4%) | 4.5 – 7.0 | |
| 6 | Ka nui o ka ʻike ʻia | g/l | 30 – 60 |
| 7 | Ka nui o ke kalapona | m/m% | 3.5 – 5.5 |
Hoʻohana Huahana
Hoʻohana nui ʻia i nā uhi ʻana, nā mea hoʻopili, nā mea hoʻopaʻa, nā toner kope, nā resins epoxy a me vinyl a me nā resins gelcoat, ke kāpili uwea, nā mea humuhumu, nā mea hoʻopau i nā foam a me nā ʻoihana ʻē aʻe;
Ka Hoʻopili ʻana a me ka Mālama ʻana
1. Hoʻopili ʻia i loko o ka pepa kraft papa he nui
2. Nā ʻeke 10kg ma ka pallet
3. Pono e mālama ʻia i loko o ka pahu kumu ma kahi maloʻo
4. Pale ʻia mai nā mea lele
