Nā ʻano mālama a me ka halihali o ka hydroxyethyl cellulose
Hoʻopili ʻia: ʻeke pālua papa, ʻeke pepa hui waho, ʻeke ʻoniʻoni polyethylene kūloko, kaumaha upena 20kg a i ʻole 25kg no kēlā me kēia ʻeke.
Ka mālama ʻana a me ka halihali ʻana: E mālama i kahi maloʻo a me kahi ea i loko, a e makaʻala i ka makū. Palekana i ka ua a me ka lā i ka wā e halihali ʻia ai.

Ke ʻano hana hoʻomākaukau no ka hydroxyethyl cellulose
ʻAno Hana 1: E hoʻomohu i nā ʻōmole pulupulu maka a i ʻole ka pulp i hoʻomaʻemaʻe ʻia i loko o 30% lye, e lawe i waho ma hope o ka hapalua hola, a kaomi. E kaomi a hiki i ka lakio o ka wai alkali i 1:2.8, a neʻe i kahi mea wili no ka wili ʻana. E hoʻokomo i ka fiber alkali i wili ʻia i loko o ka ipuhao hopena. Sila ʻia a hoʻoneʻe ʻia, hoʻopiha ʻia me ka nitrogen. Ma hope o ka hoʻololi ʻana i ka ea i loko o ka ipuhao me ka nitrogen, e kaomi i loko o ka wai ethylene oxide i hoʻomaʻalili mua ʻia. E hana ma lalo o ka hoʻomaʻalili ʻana ma 25°C no 2 hola e loaʻa ai ka hydroxyethyl cellulose maka. E holoi i ka huahana maka me ka waiʻona a hoʻoponopono i ka waiwai pH i 4-6 ma ka hoʻohui ʻana i ka waikawa acetic. E hoʻohui i ka glyoxal no ka cross-linking a me ka ʻelemakule, holoi koke me ka wai, a ma hope e centrifuge, maloʻo, a wili e loaʻa ai ka hydroxyethyl cellulose paʻakai haʻahaʻa.
ʻAno Hana 2: He polymer kūlohelohe ka alkali cellulose, aia i loko o kēlā me kēia apo kumu fiber ʻekolu mau hui hydroxyl, ʻo ka hui hydroxyl ikaika loa e hana i ka hydroxyethyl cellulose. E hoʻomohu i nā linter pulupulu maka a i ʻole ka pulp i hoʻomaʻemaʻe ʻia i loko o ka 30% soda caustic wai, e lawe i waho a kaomi ma hope o ka hapalua hola. E ʻomi a hiki i ka ratio o ka wai alkaline i 1: 2.8, a laila e kuʻi. E hoʻokomo i ka cellulose alkali i pulverized ʻia i loko o ka ipuhao pane, e sila iā ia, e hoʻomaʻemaʻe iā ia, e hoʻopiha iā ia me ka nitrogen, a hana hou i ka vacuumization a me ka hoʻopiha nitrogen e hoʻololi piha i ka ea i loko o ka ipuhao. E kaomi i loko o ka wai ethylene oxide i hoʻomaʻalili mua ʻia, e hoʻokomo i ka wai hoʻoluʻu i loko o ka ʻaʻahu o ka ipuhao pane, a e kāohi i ka hopena ma kahi o 25°C no 2 mau hola e loaʻa ai ka hydroxyethyl cellulose maka. Holoi ʻia ka huahana maka me ka waiʻona, hoʻopau ʻia i ka pH 4-6 ma ka hoʻohui ʻana i ka waikawa acetic, a hoʻopili ʻia me ka glyoxal no ka ʻelemakule. A laila holoi ʻia me ka wai, hoʻomaloʻo ʻia e ka centrifugation, hoʻomaloʻo a pulverized e loaʻa ai ka hydroxyethyl cellulose. ʻO ka hoʻohana ʻana i nā mea maka (kg/t) nā linters pulupulu a i ʻole ka pulp haʻahaʻa 730-780 soda caustic wai (30%) 2400 ethylene oxide 900 waiʻona (95%) 4500 waikawa acetic 240 glyoxal (40%) 100-300
He pauka keʻokeʻo a melemele paha ka Hydroxyethyl cellulose, ʻono ʻole a maʻalahi ke kahe ʻana, hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a maʻamau ʻaʻole hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik.
ʻO ka Hydroxyethyl cellulose (HEC) he mea paʻa fibrous a pauka paha keʻokeʻo a melemele māmā paha, ʻaʻohe ʻala, ʻaʻohe mea ʻawahia, i hoʻomākaukau ʻia e ka hopena etherification o ka cellulose alkaline a me ka ethylene oxide (a i ʻole chlorohydrin). ʻO nā ethers cellulose soluble nonionic. No ka mea, he mau waiwai maikaʻi ko HEC no ka hoʻomānoanoa, ka hoʻokuʻu ʻana, ka hoʻopuehu ʻana, ka emulsifying, ka hoʻopaʻa ʻana, ka hana ʻana i nā kiʻiʻoniʻoni, ka pale ʻana i ka makū a me ka hāʻawi ʻana i ka colloid pale, ua hoʻohana nui ʻia ia i ka ʻimi ʻaila, nā uhi, ke kūkulu ʻana, ka lāʻau lapaʻau, ka meaʻai, ka lole, ka pepa a me ka polymer Polymerization a me nā ʻoihana ʻē aʻe. 40 mesh sieving rate ≥ 99%; mahana palupalu: 135-140°C; ʻike ʻia ka nui: 0.35-0.61g/ml; mahana decomposition: 205-210°C; wikiwiki o ka puhi ʻana; mahana kaulike: 23°C; 50% 6% ma rh, 29% ma 84% rh.

Pehea e hoʻohana ai i ka hydroxyethyl cellulose
hoʻohui pololei ʻia i ka manawa hana
1. E hoʻohui i ka wai maʻemaʻe i loko o kahi bākeke nui i lako me kahi mea hoʻohuihui shear kiʻekiʻe.
ʻO ka cellulose hydroxyethyl
2. E hoʻomaka e hoʻoulu mau i ka wikiwiki haʻahaʻa a kānana mālie i ka hydroxyethyl cellulose i loko o ka hopena like. ka
3. E hoʻomau i ka hoʻoulu a hiki i ka pulu ʻana o nā ʻāpana āpau.
4. A laila e hoʻohui i ka mea pale uila, nā mea hoʻohui kumu e like me nā pigments, nā mea kōkua hoʻopuehu, ka wai ammonia.
5. E hoʻowali a hiki i ka wā e hoʻoheheʻe loa ʻia ai ka hydroxyethyl cellulose (piʻi nui ka mānoanoa o ka hopena) ma mua o ka hoʻohui ʻana i nā mea ʻē aʻe i loko o ke ʻano hana, a wili a hiki i ka huahana i pau.
Ua hoʻolako ʻia me ka waiʻona makuahine
ʻO kēia ʻano hana, ʻo ia ka hoʻomākaukau mua ʻana i ka waiʻona makuahine me ka nui o ka hoʻohuihui ʻana, a laila hoʻohui iā ia i ka pena latex. ʻO ka pōmaikaʻi o kēia ʻano hana, ʻoi aku ka maʻalahi o kona ʻano 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 hana 1, ʻo ka ʻokoʻa, ʻaʻohe pono e hoʻoulu a hiki i ka wā e hoʻoheheʻe loa ʻia ai i loko o kahi hopena viscous.
ʻO ka porridge no ka phenology
ʻOiai he mau mea hoʻoheheʻe maikaʻi ʻole nā ​​mea hoʻoheheʻe organik no ka hydroxyethyl cellulose, hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe organik e hoʻomākaukau i ka porridge. ʻO nā mea hoʻoheheʻe organik i hoʻohana pinepine ʻia he mau wai organik 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 nā ʻano pena. He mea hoʻoheheʻe maikaʻi ʻole hoʻi ka wai hau, no laila hoʻohana pinepine ʻia ka wai hau me nā wai organik e hoʻomākaukau i ka porridge. Hiki ke hoʻohui pololei ʻia ka hydroxyethyl cellulose o ka porridge i ka pena, a ua māhele ʻia ka hydroxyethyl cellulose a pehu i loko o ka porridge. Ke hoʻohui ʻia i ka pena, hoʻoheheʻe koke ia a hana ma ke ʻano he mea hoʻomānoanoa. Ma hope o ka hoʻohui ʻana, e hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻoheheʻe loa ʻia ʻana o ka hydroxyethyl cellulose a like. Ma ke ʻano laulā, hana ʻia ka porridge ma ke kāwili ʻana i ʻeono ʻāpana o ka mea hoʻoheheʻe organik a i ʻole ka wai hau me hoʻokahi 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 i ka porridge.

Nā akahele no ka hydroxyethyl cellulose
ʻOiai he pauka a he paʻa cellulose paha ka hydroxyethyl cellulose i mālama ʻia ma ka ʻili, he maʻalahi ke lawelawe a hoʻoheheʻe iā ia i loko o ka wai inā e nānā pono ʻia nā mea aʻe.
1. Ma mua a ma hope o ka hoʻohui ʻana i ka hydroxyethyl cellulose, pono e hoʻoulu mau ʻia a hiki i ka wā e moakāka loa ai ka hopena.
2. Pono e kānana mālie ʻia i loko o ka pahu hui ʻana, mai hoʻohui pololei i ka nui o ka hydroxyethyl cellulose a i ʻole hydroxyethyl cellulose i hana i nā puʻupuʻu a me nā pōpō i loko o ka pahu hui. 3. Loaʻa ka pilina maopopo o ka mahana o ka wai a me ka waiwai PH i loko o ka wai i ka hoʻoheheʻe ʻia ʻana o ka hydroxyethyl cellulose, no laila pono e uku ʻia ka nānā kūikawā. 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 ma o ka wai. ʻO ka hoʻokiʻekiʻe ʻana i ka waiwai pH ma hope o ka hoʻomehana ʻana e kōkua i ka hoʻoheheʻe ʻana.
5. I ka hiki loa, e hoʻohui i ka mea anti-fungal i ka wā hikiwawe loa.
6. I ka wā e hoʻohana ai i ka hydroxyethyl cellulose kiʻekiʻe-viscosity, ʻaʻole pono e ʻoi aku ka nui o ka waiʻona makuahine ma mua o 2.5-3%, a i ʻole e paʻakikī ke lawelawe ʻana i ka waiʻona makuahine. ʻAʻole maʻalahi ka hana ʻana i nā puʻupuʻu a i ʻole nā ​​​​spheres o ka hydroxyethyl cellulose ma hope o ka mālama ʻana, ʻaʻole hoʻi e hana i nā colloids spherical insoluble ma hope o ka hoʻohui ʻana i ka wai.
Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻomānoanoa, mea pale, mea hoʻopili, mea hoʻopaʻa a me ka mea hoʻohui no ka hoʻomākaukau ʻana i ka emulsion, jelly, poni, lotion, mea hoʻomaʻemaʻe maka, suppository a me ka papa, a hoʻohana ʻia hoʻi ma ke ʻano he gel hydrophilic a me nā mea iwi 1. Hoʻomākaukau ʻana i nā hoʻomākaukau hoʻokuʻu mau ʻano iwi. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa i ka meaʻai.
