Papa hale MHEC Methyl HydroxyethylCelulosehe pauda keʻokeʻo ʻona ʻole, ʻono ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu e hana ai i kahi hopena ʻalohilohi. Loaʻa iā ia nā hiʻohiʻona o ka mānoanoa, ka hoʻopaʻa ʻana, ka dispersion, emulsification, ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, ka hoʻokuʻu ʻana, ka adsorption, ka gelation, ka hana ʻili, ka paʻa ʻana o ka wai a me ka colloid pale. No ka mea he hana hoʻoikaika kino ka wai, hiki ke hoʻohana ʻia ma ke ʻano he mea pale colloidal, emulsifier a me dispersant. Loaʻa ka hydrophilicity maikaʻi a he mea mālama wai kūpono ʻo MHEC methyl Hydroxyethylcellulose aqueous solution. Loaʻa i ka Hydroxyethyl methyl cellulose nā pūʻulu hydroxyethyl, no laila, loaʻa iā ia ka mana anti-mold maikaʻi, kūpaʻa viscosity maikaʻi a me ka anti-mildew i ka wā mālama lōʻihi.

Nā waiwai kino a me kemika:

ʻAno: MHEC keʻokeʻo a ʻaneʻane keʻokeʻo fibrous a granular pauka; ʻala ʻole.

Solubility: Hiki i ka MHEC ke hoʻoheheʻe i ka wai anuanu a me ka wai wela, hiki i ka L model ke hoʻoheheʻe wale i ka wai anuanu, ʻaʻole hiki ke hoʻoheheʻe ʻia ka MHEC i ka hapa nui o nā mea hoʻoheheʻe organik. Ma hope o ka mālama ʻana i ka ʻili, hoʻopuehu ka MHEC i ka wai anuanu me ka ʻole o ka agglomeration, a hoʻoheheʻe lohi, akā hiki ke hoʻopau koke ʻia ma ka hoʻoponopono ʻana i kāna waiwai PH o 8 ~ 10.

PH paʻa: Hoʻololi liʻiliʻi ka viscosity i loko o ka laulā o 2 ~ 12, a emi ka viscosity ma mua o kēia pae.

Hiki ke hoʻohana ʻia ka papa hale MHEC methyl Hydroxyethyl cellulose ma ke ʻano he colloid pale, emulsifier a me ka dispersant ma muli o kāna hana ʻeleʻele i loko o kāna ʻano wai. Eia nā laʻana o kāna mau noi:

1. ʻO ka hopena o ka methylhydroxyethylcellulose ma ka hana sima. ʻO ka papa hale MHEC methylHydroxyethylcellulose he pauka keʻokeʻo ʻono ʻole, ʻono ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu e hana i kahi hopena viscous akaka. Loaʻa iā ia nā hiʻohiʻona o ka mānoanoa, ka hoʻopaʻa ʻana, ka dispersion, emulsification, ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, ka hoʻokuʻu ʻana, ka adsorption, ka gelation, ka hana ʻili, ka paʻa ʻana o ka wai a me ka colloid pale. No ka loaʻa ʻana o ka hana ʻana o ka wai, hiki ke hoʻohana ʻia e like me ka colloid pale, emulsifier a me dispersant.Building grade MHEC methyl Hydroxyethyl cellulose aqueous solution he hydrophilicity maikaʻi a he mea mālama wai kūpono.
2. E hoʻomākaukau i kahi pena hoʻomaha me ka hiki ke maʻalahi, i hana ʻia i nā ʻāpana e like me ke kaumaha o nā mea maka: 150-200g o ka wai deionized; 60-70g o ka emulsion acrylic maʻemaʻe; 550-650g o ka calcium kaumaha; 70-90g o ka talc; 30-40g o ka methyl cellulose aqueous solution; 10-20g o ka lignoscellulose aqueous solution; 4-6g o nā mea hana kiʻiʻoniʻoni; 1.5-2.5g o ka antiseptic fungicide; 1.8-2.2g o ka dispersant; 1.8-2.2g o ka mea hoʻomaʻemaʻe; Mānoanoa 3.5-4.5g; ethylene glycol 9-11g; ua hana ʻia ka ʻōnaehana wai MHEC hale me ka 2-4% Building grade MHEC i hoʻoheheʻe ʻia i ka wai; kapuluniu celluloseHana ʻia ka wai wai o 1 -3%puluniu cellulosehana ʻia ma ka hoʻoheheʻe ʻana i ka wai.

Pehea e hana aiPapa hale MHEC？

ʻO kahana ʻanaʻO ke ʻano o ke kūkulu ʻana i ka papa MHEC methyl hydroxyethyl cellulose ʻo ia ka hoʻohana ʻana i ka pulupulu hoʻomaʻemaʻe ma ke ʻano he mea maka a hoʻohana ʻia ka ethylene oxide ma ke ʻano he etherifying agent e hoʻomākaukau ai i ka hale MHEC. Hoʻomākaukau ʻia nā mea maka no ka hoʻomākaukau ʻana i ka hale papa MHEC ma nā ʻāpana ma ke kaupaona: 700-800 mau ʻāpana o toluene a me ka hui isopropanol e like me ka solvent, 30-40 mau ʻāpana wai, 70-80 mau ʻāpana o ka sodium hydroxide, 80-85 mau ʻāpana o ka pulupulu hoʻomaʻemaʻe, apo 20-28 ʻāpana o ka oxyethane, 80-90 ʻāpana o ka methyl chloride, 16-19 ʻāpana o ka glacial acetic ʻakika; ʻo nā ʻanuʻu kikoʻī penei:

I ka hana mua, e hoʻohui i ka hui ʻana o toluene a me isopropanol, ka wai, a me ka sodium hydroxide i loko o ka ipu aniani, hoʻokiʻekiʻe i ka mahana i 60-80 ° C, a mālama iā ia no 20-40 mau minuke;

ʻO ka lua o ka ʻanuʻu, alkalization: hoʻoluʻu i nā mea i luna i 30-50 ° C, hoʻohui i ka pulupulu i hoʻomaʻemaʻe ʻia, kāpī ʻia me ka hui ʻana o toluene a me isopropanol, hoʻokuʻu i 0.006Mpa, hoʻopiha me ka nitrogen no 3 mau pani, a hana i ka alkalis ma hope o ka hoʻololi ʻana. penei: ʻO ka manawa alkaliization he 2 hola, a ʻo ka mahana alkaliization he 30 ℃-50 ℃;

ʻO ke kolu o ka ʻanuʻu, etherification: ma hope o ka alkalization, hoʻokuʻu ʻia ka reactor i 0.05～Hoʻohui ʻia ka 0.07MPa, ethylene oxide a me methyl chloride a mālama ʻia no 30～50 minuke; ka pae mua o ka etherification: 40～60 ℃, 1.0～2.0 hola, mālama ʻia ke kaomi ma waena o 0.15-0.3Mpa; ka lua o ka etherification: 60～90 ℃, 2.0～2.5 mau hola, mālama ʻia ke kaomi ma waena o 0.4-0.8Mpa;

ʻO ka ʻehā o ka pae, neutralization: hoʻohui i ka metered glacial acetic acid i mua i ka desolventizer, kaomi i loko o ka mea etherified no ka neutralization, hoʻonui i ka mahana i 75～80 ℃ no ka desolventization, e piʻi ka mahana i 102 ℃, a ʻo ka pH waiwai he 68. Ke pau ka desolvation; E hoʻopiha i ka ipu hao me ka wai paila i mālama ʻia e ka mea hoʻohuli osmosis ma 90 ℃～100 ℃;

ʻO ka lima o ka ʻanuʻu, ka holoi centrifugal: ʻo nā mea i loko o ka ʻanuʻu ʻehā e centrifuged e ka centrifuge screw horizontal, a ua hoʻoneʻe ʻia nā mea i hoʻokaʻawale ʻia i kahi ipu holoi i hoʻopiha ʻia me ka wai wela ma mua no ka holoi ʻana i nā mea;

ʻO ke ono o ka ʻanuʻu, ka hoʻomaloʻo centrifugal: lawe ʻia nā mea i holoi ʻia i loko o ka mea maloʻo ma o ka centrifuge screw horizontal, maloʻo nā mea ma 150-170 ° C, a ʻoki ʻia nā mea maloʻo a hoʻopaʻa ʻia.

Hoʻohālikelike ʻia me ka ʻenehana hana cellulose ether i kēia manawa, i kēia manawahana hanahoʻohana i ka ethylene oxide ma ke ʻano he etherifying agent no ka hoʻomākaukau ʻana i ka Building grade MHEC methyl hydroxyethyl cellulose, a no ka loaʻa ʻana o nā pūʻulu hydroxyethyl, loaʻa iā ia ka mana antifungal maikaʻi. ʻO ke kūpaʻa viscosity maikaʻi a me ka pale ʻana i ka maʻi i ka wā mālama lōʻihi. Hiki iā ia ke pani i nā ether cellulose ʻē aʻe.

Building grade MHEChe cellulose ether derivatives,ʻO ka cellulose ether kahi mea kemika maikaʻi polymer me kahi ākea o nā hoʻohana i hana ʻia mai ka cellulose polymer maoli ma o ka mālama kemika. Ma muli o ka hana ʻia ʻana o ka cellulose nitrate a me ka cellulose acetate i ke kenekulia 19, ua hoʻomohala ka poʻe chemist i nā moʻo o ka cellulose derivatives o cellulose ethers. Ke ʻike mau ʻia nei nā kahua noi hou a ua komo nā ʻāpana ʻoihana he nui. ʻO nā huahana cellulose ether e like me ka sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) A me ka methyl hydroxypropyl cellulose (MHPC) a me nā cellulose ethers ʻē aʻe. Ua hoʻohana nui ʻia ka "monosodium glutamate industrial" a me ka papa hale MHEC i ka tile pipili, mortar maloʻo, sima a me gypsum plasters etc.
