He aha ka Hydroxyethyl cellulose?
ʻO ka Hydroxyethyl cellulose (HEC) he melemele keʻokeʻo a ʻulaʻula paha, ʻaʻala ʻole, fibrous a i ʻole pauka paʻa, i hoʻomākaukau ʻia e ka hopena etherification o ka cellulose alkaline a me ka ethylene oxide (a i ʻole chlorohydrin).
1.Na kuhikuhi
1.1 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.
2. E hoʻomaka e hoʻoulu mau me ka māmā haʻahaʻa a kānana mālie i ka hydroxyethyl cellulose i loko o ka hopena.
3. E hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o nā ʻāpana āpau.
4. A laila e hoʻohui i ka antifungal agent, alkaline additives e like me ka puaʻa, nā mea hoʻopuehu, ka wai amonia.
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.
1.2 Hoʻomākaukau 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 ʻia ʻana i loko o kahi solution viscous.
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 ʻia ʻana i loko o kahi solution viscous.
2.Porridge no ka phenology
No ka mea ʻo nā mea hoʻoheheʻe organik he mau mea hoʻoheheʻe maikaʻi ʻole nohydroxyethyl cellulose, hiki ke hoʻohana i kēia mau mea hoʻoheheʻe organik e hoʻomākaukau 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 mau ʻāpana o ka solvent 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.
3.Application kahua
Hydroxyethyl cellulose Hoʻohana ʻia e like me nā adhesives, surfactants, colloidal protection agents, dispersants, etc.
Loaʻa iā ia ka nui o nā noi i ka pena, pena, fiber, dyeing, papermaking, cosmetics, pesticides, mineral processing, oil recovery agents, and medicine.
1. Hydroxyethyl cellulose ua hoʻohana maʻamau e like me ka mānoanoa, mea pale, adhesive, stabilizer a me ka additive no ka hoomakaukau ana i ka emulsion, jelly, aila, lotion, maka hoʻomaʻemaʻe, suppository a me ka papa, a ua hoʻohana 'ia e like me ka hydrophilic gel a me ka iwi iwi, hoomakaukau o matrix-type sustained-release hoʻomākaukau, a hiki ke hoʻohana ʻia ma ke ʻano he stabilizer i ka meaʻai.
2. Hydroxyethyl cellulose Hoʻohana ʻia ma ke ʻano he mea nui i ka ʻoihana textile, a ma ke ʻano he mea kōkua no ka hoʻopaʻa ʻana, mānoanoa, emulsifying, a me ka hoʻopaʻa ʻana i nā ʻoihana uila a me nā ʻoihana māmā.
3. Hoʻohana ʻia ʻo ia ma ke ʻano he mānoanoa a me ka hoʻohaʻahaʻa ʻana i ka wai no ka wai hoʻoheheʻe wai a me ka wai hoʻopau, a ʻike ʻia ka hopena mānoanoa i ka wai hoʻoheheʻe brine. Hiki ke hoʻohana ʻia e like me ka hoʻohaʻahaʻa ʻana i ka wai no ka luawai aila sima. Hiki ke hoʻopili ʻia me nā ion metala polyvalent e hana i kahi gel.
4. Hoʻohana ʻia ka huahana hydroxyethyl cellulose ma ke ʻano he dispersant no ka polymerization o ka petroleum wai-based gel fracturing fluid, polystyrene a me polyvinyl chloride, etc. Hiki ke hoʻohana ʻia ma ke ʻano he emulsion mānoanoa i ka ʻoihana pena, kahi hygrostat i ka ʻoihana uila, kahi anticoagulant sima a me kahi mea hoʻopaʻa paʻa i ka ʻoihana. ʻO ka ʻoihana seramika e hoʻoheheʻe ʻia a me ka mea hoʻopili niho. Hoʻohana nui ʻia ia i ka paʻi ʻana a me ka waihoʻoluʻu, textiles, papermaking, lāʻau lapaʻau, hoʻomaʻemaʻe, meaʻai, cigakeke, pesticides a me nā mea kinai ahi.
5. Ma keʻano he surfactant, colloidal protection agent, emulsification stabilizer no ka vinyl chloride, vinyl acetate a me nā emulsions'ē aʻe, a me ka latex tackifier, dispersant, dispersion stabilizer, a me nā mea'ē aʻe. , etc. He nui nō hoʻi kona hoʻohana ʻana i ka ʻimi ʻaila a me ka ʻoihana mīkini.
6. ʻO ka hydroxyethyl cellulose ka hana o ka ili, mānoanoa, hoʻopaneʻe, hoʻopaʻa, emulsifying, hana kiʻiʻoniʻoni, hoʻopuehu, mālama wai a me nā hana pale i ka lāʻau paʻa a me ka hoʻomākaukau wai.
7. Hoʻohana ʻia ʻo ia ma ke ʻano he polymeric dispersant no ka hoʻohana ʻana i ka wai ʻaila wai-based gel fracturing fluid, polyvinyl chloride a me ka polystyrene. Hiki ke hoʻohana ʻia ma ke ʻano he emulsion mānoanoa i loko o ka ʻoihana pena, he anticoagulant sima a me ka mea hoʻopaʻa wai i ka ʻoihana hana, kahi mea aniani a me kahi mea hoʻopili niho i ka ʻoihana seramika. Hoʻohana nui ʻia ia i nā ʻoihana ʻoihana e like me ka paʻi ʻana a me ke kala, textiles, papermaking, lāʻau lapaʻau, hoʻomaʻemaʻe, meaʻai, cigakeke a me nā pesticides.
