Ke ala no ka hoʻohana ʻana i ka hydroxyethyl cellulose i loko o ka pena latex

ʻO ka hoʻohana ʻana i ka hydroxyethyl cellulose i ka pena latex penei: 1. Hoʻohui pololei i ka wā e wili ai i ka puaʻa: maʻalahi kēia ʻano, a pōkole ka manawa i hoʻohana ʻia. Penei nā ʻanuʻu kikoʻī: (1) hoʻohui i ka wai i hoʻomaʻemaʻe ʻia (ma keʻano maʻamau, hoʻohui ʻia ka ethylene glycol, ka mea hoʻomaʻemaʻe a me ka mea hana kiʻiʻoniʻoni i kēia manawa)(2) hoʻomaka i ka hoʻoulu ʻana me ka wikiwiki haʻahaʻa mau a hoʻohui mālie i ka hydroxyethyl cellulose (3) hoʻomau i ka hoʻoulu ʻana a pulu nā ʻāpana a pau (4) hoʻohui i ka mea hoʻopuʻi maloʻo; PH regulator, etc. (5) ho'oulu a pau loa ka hydroxyethyl cellulose (solution viscosity increase) ma mua o ka ho'ohui 'ana i nā mea 'ē a'e o ka formula, e wili ana a pena.
2.Equipped me ka waiʻona makuahine e kali ana no ka hoʻohana: ua hoʻolako mua ʻia kēia ʻano me kahi kiʻekiʻe kiʻekiʻe o ka waiʻona makuahine, a laila hoʻohui ʻia i ka pena latex, ʻoi aku ka maikaʻi o kēia ʻano, hiki ke hoʻohui pono ʻia i nā huahana pena, akā pono e mālama pono ʻia. Ua like nā ʻanuʻu a me nā ʻano hana me nā ʻanuʻu (1)-(4) ma ke ʻano 1, koe wale nō ʻaʻole koi ʻia kahi mea hoʻouluulu kiʻekiʻe, a ʻo kahi mea hoʻouluulu wale nō me ka mana lawa e hoʻopuehu like ʻia ai nā fibers hydroxyethyl i loko o ka hopena. E hoʻomau i ka hoʻoulu ʻana a hiki i ka wā e hoʻoheheʻe ʻia ai i loko o kahi solution viscous. Pono e hoʻomaopopo: pono e hoʻohui ʻia ka mea hoʻopuʻi maloʻo i ka waiʻona makuahine i ka hiki. 3. Congee me ka phenology: no ka mea, he mea hoʻoheheʻe kino no ka hydroxyethyl cellulose, no laila hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe kūlohelohe e hoʻomākaukau ai i ka congee. ʻO nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethylene glycol, propylene glycol, a me nā mea hana kiʻiʻoniʻoni (e like me ka hexanediol a i ʻole diethylene glycol butyl acetate), ʻo ka wai hau he mea hoʻoheheʻe maikaʻi ʻole, no laila hoʻohana pinepine ʻia me nā wai kūlohelohe e hoʻomākaukau ai i ka porridge. Hiki ke hoʻohui pololei ʻia ka hydroxyethyl cellulose e like me Porridge i ka pena. Ua hoʻopiha piha ʻia ka Hydroxyethyl cellulose i loko o ka pā. Ke hoʻohui ʻia ka lacquer, hemo koke ia a mānoanoa. Ma hope o ka hoʻohui ʻana, pono e hoʻoulu ʻia a hiki i ka pau ʻana o ka hydroxyethyl cellulose a me ka ʻaʻahu. ʻO ka maʻamau, ʻo ka porridge me ʻeono mau ʻāpana o ka mea hoʻoheheʻe a i ʻole ka wai hau a me kahi ʻāpana o ka hui hydroxyethyl cellulose, ma kahi o 5-30 mau minuke ma hope, e hydrolyzed a pehu ka hydroxyethyl cellulose. ʻO ke kauwela ke kiʻekiʻe loa ka haʻahaʻa o ka wai, ʻaʻole kūpono no ka lako me ka porridge.
3.Eha. E hoʻomanaʻo i ka wā e hoʻomākaukau ai i ka waiʻona makuahine o ka hydroxyethyl cellulose no ka mea ʻo ka hydroxyethyl cellulose kahi ʻāpana pauka i mālama ʻia, maʻalahi ke hana a hoʻoheheʻe i ka wai ma ka nānā ʻana i kēia mau mea. 1 ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻoneʻe mau ʻia ka hui ʻana a hiki i ka ʻike a maopopo loa ka hopena. Pono e kānana ʻia ʻo 2 i loko o ka pahu hui, ʻaʻohe nui o nā puʻupuʻu a i ʻole nā ​​pōpō o ka hydroxyethyl cellulose i hoʻohui pololei ʻia i loko o ka pahu hui. 3 pili ka solubility o ka hydroxyethyl cellulose i ka mahana o ka wai a me ka waiwai o ka pH i loko o ka wai, pono e nānā pono ʻia. 4 Mai hoʻohui i kekahi mau mea maʻamau i ka hui ʻana ma mua o ka hoʻopiha ʻia ʻana o ka pauka hydroxyethyl cellulose me ka wai. ʻO ka hoʻonui ʻana i ka pH ma hope o ka hoʻoulu ʻana e kōkua i ka hoʻoheheʻe. 5 e like me ka hiki, e hoʻohui mua i ka mea anti-mildew. 6 i ka hoʻohana ʻana i ka hydroxyethyl cellulose viscosity kiʻekiʻe, ʻaʻole hiki ke kiʻekiʻe ke kiʻekiʻe o ka waiʻona makuahine ma mua o 2.5-3% (gravimeter), inā ʻaʻole paʻakikī ka hana ʻana i ka waiʻona makuahine. Nā mea e pili ana i ka viscosity o ka pena latex:
1 ʻOi aku ka nui o nā ʻōhū ea i loko o ka pena, ʻoi aku ka kiʻekiʻe o ka viscosity. 2 ua kūpono ka nui o ka mea hoʻoulu ili a me ka wai i hoʻohana ʻia i ke ʻano pena. 3 i ka synthesis o ka latex, ka nui o nā koena catalysts a me nā oxides ʻē aʻe. 4 ka nui o nā mānoanoa kūlohelohe ʻē aʻe i loko o ke ʻano pena a me ka like me ka hydroxyethyl cellulose. 5 i ke kaʻina o ka pena, e hoʻohui i ke kaʻina kapuaʻi mānoanoa kūpono. 6 ma muli o ka hoʻonāukiuki nui ʻana i ka wā i hoʻopuehu ʻia ai ka maʻamau overheating. 7 microbial corrosion o Thickener.
