01.Hydroxyethyl Cellulose
Ma ke ʻano he surfactant non-ionic, hydroxyethyl cellulose ʻaʻole wale nā hana o ka hoʻokuʻu ʻana, mānoanoa, hoʻopuehu, flotation, hoʻopaʻa ʻana, hana kiʻiʻoniʻoni, paʻa wai a me ka hāʻawi ʻana i ka colloid pale, akā loaʻa pū kekahi mau waiwai:
1. He mea hiki ke hoʻoheheʻe ʻia ka HEC i ka wai wela a i ʻole ka wai anuanu, a ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila, i loaʻa iā ia kahi ākea o ka solubility a me nā ʻano viscosity, a me ka gelation non-thermal;
2. Ke hoʻohālikelike ʻia me ka methyl cellulose i ʻike ʻia a me ka hydroxypropyl methyl cellulose, ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana o HEC, akā ʻoi aku ka ikaika o ka colloid pale.
3. ʻO ka paʻa wai paʻa ʻelua ʻoi aku ka nui o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono kahe ʻana.
E mālama i ka hoʻohana ʻana:
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 ʻike ʻia kēia mau mea.
1. Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻoneʻe mau ʻia a hiki i ka ʻike ʻana o ka hopena.
2. Pono e kānana mālie ʻia i loko o ka pahu hui. Mai hoʻohui pololei i ka hydroxyethyl cellulose i hana ʻia i mau puʻupuʻu a i ʻole pōpō i loko o ka pahu hui i ka nui a i ʻole pololei.
3. He pilina koʻikoʻi ka mahana o ka wai a me ka waiwai pH o ka wai me ka hoʻoheheʻe ʻana o ka hydroxyethyl cellulose, no laila pono ke nānā pono iā ia.
4. Mai hoʻohui i kekahi mau mea alkaline i ka hui ʻana ma mua o kahydroxyethyl cellulosePumehana ka pauda i ka wai. ʻO ka hoʻonui ʻana i ka waiwai PH ma hope o ka hoʻomehana ʻana he mea kōkua no ka hemo ʻana.
HEC hoʻohana:
1. Hoʻohana maʻamau e like me ka mānoanoa, mea pale, adhesive, stabilizer a me nā mea hoʻohui no ka hoʻomākaukau ʻana i ka emulsion, ka gel, ka ʻaila, ka lotion, ka mea hoʻomaʻemaʻe maka, suppository a me ka papa, hoʻohana pū ʻia e like me ka hydrophilic gel, nā mea iwi, ka hoʻomākaukau ʻana i ka hoʻomākaukau ʻana i ka ʻiʻo, a hiki ke hoʻohana ʻia e like me ka stabilizer i ka meaʻai.
2. Hoʻohana ʻia ʻo ia ma ke ʻano he mea nui i ka ʻoihana textile, hoʻopaʻa, mānoanoa, emulsifying, stabilizing a me nā mea kōkua ʻē aʻe i nā ʻoihana uila a me nā ʻoihana māmā.
3. Hoʻohana ʻia e like me ka mānoanoa a me ka hoʻohaʻahaʻa kānana no ka wai hoʻoheheʻe wai a me ka wai hoʻopau, a loaʻa ka hopena mānoanoa i loko o ka wai wili wai paʻakai. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomalu poho wai no ka luawai ʻaila sima. Hiki ke hoʻopili ʻia me nā ion metala polyvalent e hana i nā gels.
5. Hoʻohana ʻia kēia huahana ma ke ʻano he dispersant no ka wai-wai-wai gel fracturing fluids, polystyrene a me polyvinyl chloride i ka hana ʻaila ʻaila. Hiki ke hoʻohana ʻia e like me ka emulsion mānoanoa i loko o ka ʻoihana pena, ka resistor sensitive humidity i ka ʻoihana uila, ka mea hoʻopaʻapaʻa coagulation sima a me ka mea mālama mau i ka ʻoihana kūkulu. ʻO nā mea hoʻopili aniani a me nā niho niho no ka ʻoihana keramika. Hoʻohana nui ʻia ia i ka paʻi ʻana a me ke kala, textile, papermaking, lāʻau lapaʻau, hoʻomaʻemaʻe, meaʻai, cigakeke, pesticides a me nā mea kinai ahi.
02.Hydroxypropyl Methyl Cellulose
1. ʻOihana Hoʻopili: Ma ke ʻano he mānoanoa, dispersant a me ka stabilizer i ka ʻoihana hoʻopili, loaʻa ka hoʻohālikelike maikaʻi i ka wai a i ʻole nā mea hoʻoheheʻe organik. me he mea wehe pena.
