Pehea e hoʻohana ai i ka hydroxyethyl cellulose
hoʻohui pololei i ka manawa hana
1. E hoʻohui i ka wai maʻemaʻe i loko o kahi bākeke nui i hoʻolako ʻia me kahi hui ʻoki kiʻekiʻe. ka
Hydroxyethyl cellulose
2. E hoʻomaka e hoʻoulu mau me ka māmā haʻahaʻa a kānana mālie i ka hydroxyethyl cellulose i loko o ka hopena. ka
3. E hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o nā ʻāpana āpau. ka
4. A laila hoʻohui i ka mea hoʻomalu uila, nā mea hoʻohui kumu e like me nā puaʻa, nā mea hoʻopuehu, ka wai amonia. ka
5. E hoʻoulu a hiki i ka pau ʻana o ka hydroxyethyl cellulose (e piʻi nui ka viscosity o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i loko o ke ʻano, a wili a hiki i ka huahana i pau.
Hoʻolako ʻia me ka ʻona makuahine
ʻO kēia kaʻina hana e hoʻomākaukau mua i ka waiʻona makuahine me ka ʻoi aku ka nui, a laila hoʻohui i ka pena latex. ʻO ka pōmaikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi a hiki ke hoʻohui pololei ʻia i ka pena i hoʻopau ʻia, akā pono e mālama pono ʻia. Ua like nā ʻanuʻu me nā ʻanuʻu 1-4 ma ke ʻano 1, ʻo ka ʻokoʻa ʻaʻole pono e hoʻoulu a hiki i ka hoʻoheheʻe ʻana i loko o kahi solution viscous.
Porridge no ka phenology
No ka mea ʻo nā mea hoʻoheheʻe kūlohelohe he mau mea hoʻoheheʻe maikaʻi ʻole no ka hydroxyethyl cellulose, hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe organik e hoʻomākaukau ai i ka porridge. ʻO nā mea hoʻoheheʻe organik i hoʻohana pinepine ʻia he wai kūlohelohe e like me ka ethylene glycol, propylene glycol a me nā mea hana kiʻiʻoniʻoni (e like me ka ethylene glycol a i ʻole diethylene glycol butyl acetate) i loko o nā hana pena. He mea hoʻoheheʻe maikaʻi ʻole ka wai hau, no laila hoʻohana pinepine ʻia ka wai hau me nā wai kūlohelohe e hoʻomākaukau ai i ka porridge. Hiki ke hoʻohui ponoʻia ka hydroxyethyl cellulose o ka porridge i ka pena, a ua māheleʻia ka hydroxyethyl cellulose a pehu i ka porridge. Ke hoʻohui ʻia i ka pena, e hoʻoheheʻe koke ʻia a hana ma ke ʻano he mānoanoa. Ma hope o ka hoʻohui ʻana, e hoʻoulu ʻia a hiki i ka pau ʻana o ka hydroxyethyl cellulose a hoʻokahi. ʻO ka maʻamau, hana ʻia ka porridge ma ka hui ʻana i ʻeono ʻāpana o ka mea hoʻoheheʻe organik a i ʻole ka wai hau me kahi ʻāpana o ka hydroxyethyl cellulose. Ma hope o 6-30 mau minuke, e hydrolyzed ka hydroxyethyl cellulose a pehu maopopo. I ke kauwela, kiʻekiʻe loa ka mahana o ka wai, no laila ʻaʻole kūpono ke hoʻohana ʻana i ka porridge.

ʻO ka mālama ʻana no ka hydroxyethyl cellulose
No ka mea ʻo ka hydroxyethyl cellulose i mālama ʻia i ka ʻili he pauka a i ʻole cellulose paʻa, maʻalahi ke mālama a hoʻoheheʻe ʻia i loko o ka wai ke mālama ʻia nā mea i lalo. ka
1. Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻoulu mau ʻia a hiki i ka ʻike a maopopo loa ka hopena. ka
2. Pono e kānana mālie ʻia i loko o ka pahu hui, mai hoʻohui pololei i ka nui o ka hydroxyethyl cellulose a i ʻole ka hydroxyethyl cellulose i hana i nā puʻupuʻu a me nā pōpō i loko o ka pahu hui. 3. ʻO ka wela o ka wai a me ka waiwai o ka PH i loko o ka wai he pili maopopo loa i ka hoʻoheheʻe ʻana o ka hydroxyethyl cellulose, no laila pono e uku ʻia. ka
4. Mai hoʻohui i kekahi mau mea alkaline i ka hui ʻana ma mua o ka hoʻomehana ʻia ʻana o ka pauka hydroxyethyl cellulose i ka wai. ʻO ka hoʻonui ʻana i ka waiwai pH ma hope o ka hoʻomehana ʻana e kōkua i ka hoʻoheheʻe. ka
5. E like me ka hiki, e hoʻohui i ka anti-fungal agent i ka hiki wawe. ka
6. I ka hoʻohana ʻana i ka hydroxyethyl cellulose kiʻekiʻe-viscosity, ʻaʻole pono ke kiʻekiʻe o ka waiʻona makuahine ma mua o 2.5-3%, i ʻole e paʻakikī ka mālama ʻana i ka waiʻona makuahine. ʻAʻole maʻalahi ka hana ʻana o ka hydroxyethyl cellulose ma hope o ka mālama ʻana i nā puʻupuʻu a i ʻole nā ​​​​poe, ʻaʻole hoʻi e hana i nā colloid spherical insoluble ma hope o ka hoʻohui ʻana i ka wai.
Hoʻohana maʻamau ia e like me kahi mānoanoa, mea pale pale, adhesive, stabilizer a me nā mea hoʻohui no ka hoʻomākaukau ʻana i ka emulsion, jelly, ʻaila, lotion, hoʻomaʻemaʻe maka, suppository a me ka papa, a hoʻohana pū ʻia e like me ka hydrophilic gel a me nā mea iwi 1. Hoʻomākaukau ʻana i ka iwi- ʻano hoʻomākaukau hoʻokuʻu mau. Hiki ke hoʻohana ʻia ma ke ʻano he stabilizer i ka meaʻai.
