Hoʻohana i ka hydroxyethyl cellulose

Ma ke ʻano he surfactant non-ionic, ʻo ka hydroxyethyl cellulose nā waiwai i hoʻohui ʻia i nā hana o ka suspending, thickening, dispersing, floating, bonding, film forming, water retention and provide protective colloid:

1. HEC hiki ke hoʻoheheʻe ʻia i ka wai wela a i ʻole ka wai anuanu, ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila ʻana, 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 pale colloid.

3. ʻO ka paʻa wai paʻa ʻelua ʻoi aku ka nui ma mua o ka methyl cellulose, a ʻoi aku ka maikaʻi o ka hoʻoponopono kahe.

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 mālama ʻia nā mea i lalo.

1. Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻoulu 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 pono i ka nui o ka hydroxyethyl cellulose i hoʻokumu ʻia i nā puʻupuʻu a i ʻole 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.

4. Mai hoʻohui i kekahi mau mea alkaline i ka hui ʻana ma mua o ka hoʻomehana ʻia ʻana o ka pauka hydroxyethyl cellulose e ka wai. E kōkua ka hoʻonui ʻana i ka waiwai PH ma hope o ka hoʻomehana ʻana.

Hoʻohana ʻo HEC:

1. Hoʻohana maʻamau ia e like me kahi mānoanoa, mea pale, adhesive, stabilizer, a me nā mea hoʻohui no ka hoʻomākaukau ʻana i nā emulsions, jellies, ʻaila, nā lotions, nā mea hoʻomaʻemaʻe maka, nā suppositories a me nā papa, a ua hoʻohana ʻia hoʻi e like me ka hydrophilic gel a me ka iwi iwi. ka hoʻomākaukau ʻana o ka matrix-type sustained-release hoʻomākaukau, a hiki ke hoʻohana ʻia ma ke ʻano he stabilizer i ka meaʻai.

2. 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 kēia huahana 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.
