Pehea e hana aiMHEC papa kūkulu haleʻAʻole anei?

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

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

ʻO ka lua o ka hana, ka alkaliization: e hoʻomaʻalili i nā mea i luna a hiki i 30-50°C, e hoʻohui i ka pulupulu i hoʻomaʻemaʻe ʻia, e pīpī me ka hui ʻana o toluene a me isopropanol, e hoʻoneʻe i 0.006Mpa, e hoʻopiha me ka nitrogen no 3 mau hoʻololi, a hana i nā alkalis ma hope o ke hoʻololi ʻana. ʻO nā kūlana alkalization penei: ʻo 2 mau hola ka manawa alkalization, a ʻo 30℃ ka mahana alkalization.-50℃;

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

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

ʻO ka hana ʻelima, ka holoi ʻana i ke kikowaena: ua hoʻopili ʻia nā mea i ka hana ʻehā e kahi centrifuge wili pālahalaha, a ua hoʻoili ʻia nā mea i hoʻokaʻawale ʻia i kahi ipu holoi i piha i ka wai wela ma mua no ka holoi ʻana i nā mea;

ʻO ke ono o ka hana, ka hoʻomaloʻo centrifugal: lawe ʻia nā mea i holoi ʻia i loko o ka mea maloʻo ma o ka centrifuge wili ākea, hoʻomaloʻo ʻia nā mea ma 150-170°C, a kuʻi ʻia a hoʻopili ʻia nā mea maloʻo.

Ke hoʻohālikelike ʻia me ka ʻenehana hana cellulose ether e kū nei, ʻo kēia manawaʻano hanaHoʻohana i ka ethylene oxide ma ke ʻano he etherifying agent e hoʻomākaukau ai i ka Building grade MHEC methyl hydroxyethyl cellulose, a no ka mea he mau hui hydroxyethyl kona, he hiki ke antifungal maikaʻi. ʻO ke kūpaʻa viscosity maikaʻi a me ke kū'ē ʻana i ka mildew i ka wā mālama lōʻihi. Hiki iā ia ke pani i nā cellulose ethers ʻē aʻe.

Bpapa kūkulu MHEChe mau mea i loaʻa mai ka cellulose ether,ʻO ka Cellulose ether kahi mea kemika polymer maikaʻi me nā ʻano hoʻohana like ʻole i hana ʻia mai ka cellulose polymer kūlohelohe ma o ka mālama kemika. Mai ka hana ʻia ʻana o ka cellulose nitrate a me ka cellulose acetate i ke kenekulia 19, ua hoʻomohala nā kemika i nā moʻo he nui o nā derivatives cellulose o nā 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 ʻo methyl hydroxypropyl cellulose (MHPC) a me nā cellulose ethers ʻē aʻe i ʻike ʻia ʻo "industrial monosodium glutamate" a ua hoʻohana nui ʻia ka MHEC papa kūkulu i ka tile adhesive, dry mortar, cement a me gypsum plasters etc.
