ʻO kaolin kahi ʻano mineral non-metallic, ka mea nui i haku ʻia me kaolinite, mika. Hoʻokumu ʻia me ke koena feldspar a me ka quartz, he pālolo a me ka pālolo pōhaku i hoʻomalu ʻia e nā minerala pālolo kaolinite. ʻO ka hui nui o kaolin ka nui o nā mineral silicate i loaʻa ka alumini. He palupalu a keʻokeʻo nā ʻāpana. He aha ka hopena e hiki ai i ka ʻoihanaka sodium hexametaphosphatee hoʻohui ʻia ke hoʻopau ʻia ka slurry?
ʻO ka waiho ʻana i ke koena kaolin ke ʻano nui o ka waiho ʻana o ka kaolin, nona ka one kiʻekiʻe. ʻO ka mea maʻamau, pono e wehe i ke one a mālama wale i ka lepo i loko o ka hoʻohana ʻana. ʻO ka hoʻohana ʻana i ka sodium h6-metaphosphate ʻoihana e like me ka dispersant hiki ke hana maikaʻi i ka hoʻokaʻawale ʻana o ka lepo a me ke one a pale i ka pau ʻole o nā kumuwaiwai.
I kēia manawa, ʻo ke kaʻina hana o ka wehe ʻana i ke one e hoʻohana maʻamau i ke ʻano o ka slurry desanding, e hoʻohui i ka dispersant i ka slurry, i hiki ke hoʻokaʻawale ʻia ka lepo a me ke one i loko o ka ʻaila kaolin. Wehe ʻia ke one e ka umekaumaha, a loaʻa ka slurry kaolin. ʻO ka dispersant i hoʻohana nui ʻia he ʻoihanaka sodium hexametaphosphate, no ka mea oihanaka sodium hexametaphosphatemaikaʻi ka hopena kaʻawale.
Nā ʻanuʻu hana kikoʻī o ka hoʻohana ʻana i ka ʻoihanaka sodium hexametaphosphatee wehe i ke one mai ka slurry kaolin penei:
1. Ka hoʻomākaukau ʻana i ka slurry: kaolin raw ore i hui pū ʻia me ka wai, hoʻohui i ka hopena alkali e hoʻoponopono i ka waiwai pH, kaolin slurry;
2 ka hoʻomākaukau ʻana i ka dispersant: ʻoihanaka sodium hexametaphosphatea me ka sodium silicate i hoʻohui ʻia i ka wai, i hui ʻia e loaʻa i kahi dispersant pūhui;
3. Slurry: ka hoʻohana ʻana i ka ʻoihanaka sodium hexametaphosphatehoʻohui pū ʻia ka dispersant i ka slurry kaolin, ma hope o ka hui ʻana i ka slurry;
4. Wehe ʻia ke one: hoʻoneʻe ʻia ke one quartz i loko o ka pulp i hoʻopuehu ʻia ma lalo o ka hana o ka umekaumaha, a loaʻa ka pulp kaolin ma hope o ka wehe ʻana i ke one.
ʻO ka ʻoihanaka sodium hexametaphosphatehana ʻia e Shandong Jufu Chemical Technology Co., Ltd. i hana ʻia e ke kaʻina hana wela, me ka liʻiliʻi o nā haumia, ka maikaʻi paʻa a me ka liʻiliʻi o ka dosage.
