ʻO Hydroxypropylmethylrubicin (HPMC) kahi mea cellulosic, pulp a pulupulu paha i hiki ke hoʻohana ʻia e hoʻomaʻemaʻe i ka pulp lāʻau. Ma mua o ka hoʻopau ʻia ʻana o ka alkalization a i ʻole ka alkalization. Mechanical pōʻino hiki ke luku i ka aggregate hana o ka pepa cellulose mea, ma laila e ho'ēmi i ka polymerization a me ka crystallinity, hoonui i kona kiko'ī āpana, ma laila e hoʻonui i ka matrix hiki ke macromolecular ternary a me ka cellulose.
Hoʻohana ʻia ʻo Hydroxymethylcellulose ma ke ʻano he substrate i ka hana ʻaila. Hiki i ke kumu hoʻohālike ke hoʻopau i ka hoʻohana ʻana i ke kō, hoʻomaikaʻi i ka nui o ka hoʻohana ʻana i nā mea, hoʻemi i ke koena o ka substrate i loko o ka wai fermentation, a hoʻemi i ke kumukūʻai o ka mālama ʻana i ka wai. ʻO nā hiʻohiʻona o ka hui ʻana e kūpono i ka optimization o ka batch, fed-batch a me ka hoʻomau ʻana i nā kaʻina hana fermentation, e pale ana i ka manipulation o nā mea waena a me nā helu dilution, a me ka hoʻomaʻamaʻa ʻana i ka hoʻoponopono ʻana i nā kaʻina hana fermentation. Ma muli o ka hana like o ka HPMC e like me nā ethers hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻohana ʻia ma ke ʻano he mea hana kiʻiʻoniʻoni, mānoanoa, emulsifier a me ka stabilizer no ka pena latex a me ka wai-soluble resin pena, me ke kūpaʻa maikaʻi loa, ka uhi like ʻana a me ka hoʻopili. ka hoʻomaikaʻi ʻana i ka ʻili o ka ʻili, ka paʻa o ka acid-base a me ka hoʻohālikelike ʻana me nā puaʻa metala.
ʻO ka hui ʻana o ka hydroxypropylmethylcellulose (HPMC) he pilikia, akā ma ke kumu, akā nalo ka substrate, base..etherification, dissolution
ʻO ka hoʻihoʻi ʻana o ka Agena ma o ka centrifugation, ka holoi ʻana, ka hoʻomaloʻo ʻana a me ka hoʻopā ʻana i kēlā me kēia kaiapuni he waiwai maoli i nā mākau kumu a me ka ʻike.
E kōkua nā mea kōkua a me nā mana ma o ka wati e hōʻoia i ka maikaʻi o ka huahana a me kahi ʻōnaehana hana hilinaʻi. Hoʻopilikia i ka nui o ka wai i loko o ka hypromellose dry-mix mortar o ka wai paʻa hydroxypropyl methylcellulose ether mortar e paipai i ka hydration mau o ka cement, mortar a me ka substrate e hoʻonui i ka manawa adhesion.
Aia ka hopena nui o ka paʻa ʻana o ka wai, ka paʻa ʻana o ka wai, ka paʻa ʻana o ka moisture he putty pauka, adhesion a me nā hana lubrication. Hoʻohana nui ʻia i ka ʻoihana kūkulu, ʻoihana pena a me nā ʻoihana ʻē aʻe he nui, hydroxypropyl methylcellulose ka mea nui no kaka hana ʻana i ka hydroxypropyl methylcellulose. ʻOi aku ka kiʻekiʻe o ka wela wela ma mua o ka methylcellulose. He liʻiliʻi ka hopena o ka lime a me ka soda i ka hana, akā hiki ke hoʻolōʻihi i ka hemo ʻana o ka matrix a hoʻonui i ka viscosity. I ka wā polyvinyl waiʻona, starch ether, mea ʻai a me ka hydroxypropyl methylcellulose pena, a me nā mea ʻē aʻe, ka hoʻonā waiwai o ka hale i luna. Ke hoʻohana nei i ka mortar, gypsum, putty pauka a i ʻole nā mea ʻē aʻe e like me ka hoʻopili, hiki ke hoʻomaikaʻi i ka hana a hoʻolōʻihi i ka manawa hana. Hiki ke hoʻohana ʻia no ka hoʻonani ʻana, hoʻopili i nā tile, marble, plastic a hoʻemi i ka hoʻohana ʻana i ka cement false stem. ʻAʻole hikiwawe loa ka slurry mālama wai ma hope o ka maloʻo ʻana, a hoʻomaikaʻi ka ikaika ma hope o ka hoʻōla ʻana.
