Hydroxyethyl Cellulose (HEC) He nui kona mau hana, e like me: mānoanoa, hoʻopaneʻe, hoʻopaʻa, emulsifying, hana kiʻiʻoniʻoni, hoʻopaʻa, hoʻopuehu, mālama i ka wai, a hana i nā colloids pale.Hiki ke hoʻoheheʻe ʻia i loko o ka wai wela a i ʻole ka wai anuanu, hiki ke hoʻopili ʻia i loko o nā ʻano viscosities ākea, a he kūpaʻa maikaʻi loa i nā electrolytes dissolved.
ala hoʻokahi)
Hoʻohui pololei i ka wā e wili ai i ka puaʻa:
1. E hoʻohui i ka wai hoʻomaʻemaʻe kūpono i loko o kahi bākeke nui i hoʻolako ʻia me kahi mea hoʻoulu kiʻekiʻe (ʻo ka mea maʻamau, hoʻohui ʻia ka ethylene glycol, ka mea hoʻomaʻemaʻe a me ka mea hana kiʻiʻoniʻoni i kēia kaʻina).
2. E hoʻomaka i ka hoʻoulu ʻana 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 pigment dispersing aids, 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 lilo i pena.
Hana ʻelua)
Hoʻolako ʻia me ka waiʻona makuahine no ka hoʻohana ʻana:
ʻO kēia ʻano hana ka hoʻomākaukau mua ʻana i ka waiʻona makuahine me ka ʻoi aku ka kiʻekiʻe, a laila hoʻohui i ka pena latex.ʻO ka maikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi a hiki ke hoʻohui pololei ʻia i ka pena i hoʻopau ʻia, akā pono ke mālama pono.Ua like nā ʻanuʻu me nā ʻanuʻu 1-4 ma ke ʻano (1), ʻo ka ʻokoʻa ʻaʻole pono ka mea hoʻouluulu kiʻekiʻe, a ʻo kekahi mau mea hoʻouluulu me ka mana kūpono e mālama i ka hydroxyethyl cellulose i hoʻopuehu like ʻia i loko o ka hopena hiki ke hoʻohana ʻia. .E hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻoheheʻe ʻia ʻana i loko o kahi solution viscous.Pono e hoʻomaopopo ʻia e hoʻohui ʻia ka mea antifungal i ka waiʻona makuahine i ka hiki.

No ka porridge-like 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 kūlohelohe i hoʻohana pinepine ʻia he wai kūlohelohe e like me ka ethylene glycol, propylene glycol, a me nā mea hana kiʻiʻoniʻoni (e laʻa, hexanediol a i ʻole Butyl CARBITOL acetate) i 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 pololei ʻia ka hydroxyethyl cellulose e like me ka porridge i ka pena.Ua lawa pono ka pehu o ka hydroxyethyl cellulose i loko o ka mokuʻāina porridge.Ke hoʻohui ʻia i ka pena, hoʻoheheʻe koke ia a mānoanoa.Ma hope o ka hoʻohui ʻana, pono e hoʻomau i ka hoʻoulu ʻana a hiki i ka pau ʻana o ka hydroxyethyl cellulose a hoʻopau like.
ʻO ka maʻamau, ua hui pū ʻia ka porridge me ʻeono ʻāpana o ka solvent organik a i ʻole ka wai hau a me kahi ʻāpana o ka hydroxyethyl cellulose.Ma hope o 5-30 mau minuke, e hydrolyzed ka hydroxyethyl cellulose a pehu maopopo.I ke kauwela, kiʻekiʻe loa ka mahana o ka wai, a ʻaʻole kūpono ia no ka porridge.
Nā mea e pono ai ka nānā ʻana i ka wā e hoʻomākaukau ai i ka waiʻona makuahine hydroxyethyl cellulose:
ʻO ka Hydroxyethyl cellulose ka mea maʻamau i ka pauka a me nā mea granular.I ka wā e ʻike ʻia ai kēia mau mea, maʻalahi ke mālama a hoʻoheheʻe ʻia i ka wai.
1. Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, e hoʻoikaika mau 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.
3. ʻO ka mahana o ka wai a me ka pH waiwai o ka wai he pilina maopopo me ka hoʻoheheʻe ʻana o ka hydroxyethyl cellulose, no laila pono e nānā pono iā ia.
4. Mai hoʻohui i kekahi mau mea alkaline 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 wale nō ma hope o ka pulu ʻana e kōkua i ka hemo ʻana.
5. E like me ka hiki, e hoʻohui i ka lāʻau antifungal i ka wā hiki.
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% (ma ke kaupaona), inā ʻaʻole e paʻakikī ka inu ʻana o ka makuahine.
