ʻO ka hydroxypropyl methylcellulose kahi kūpono kūpono

Hana ʻia ʻo Hydroxypropyl methylcellulose mai ka cellulose pulupulu maʻemaʻe ma o ka etherification kūikawā ma lalo o nā kūlana alkaline, a ua hoʻopau ʻia ke kaʻina holoʻokoʻa ma lalo o ka nānā ʻana. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka etera, acetone a me ka ethanol piha, a pehu i loko o kahi hopena colloidal māmā a ʻeleʻele paha i loko o ka wai anuanu. Loaʻa i ka hoʻonā wai i ka hana ʻili, ke ʻike kiʻekiʻe a me ka hana paʻa. Hiki ke hoʻohana ʻia e like me ka paʻi tile, ka marble, ka mea hoʻonaninani plastik, ka hoʻopili ʻana i ka hoʻoikaika ʻana, a hiki ke hoʻemi i ka nui o ka sima. ʻO ka hana paʻa wai o ka hydroxypropyl methyl fiber e pale i ka slurry mai ka haki ʻana ma muli o ka maloʻo wikiwiki loa ma hope o ka noi ʻana, a hoʻonui i ka ikaika ma hope o ka paʻakikī.

Me ka emi ʻana o ka methoxyl maʻiʻo, piʻi ka helu gel, hoʻemi ka solubility i ka wai, a emi pū ka hana ʻili. Loaʻa i ka huahana nā hiʻohiʻona o ka hiki ke mānoanoa, ke kūpaʻa paʻakai, ka pauka lehu haʻahaʻa, ka paʻa pH, ka paʻa ʻana o ka wai, ke kūpaʻa dimensional, ka hana kiʻiʻoniʻoni maikaʻi loa, a me ka nui o ka pale ʻana o ka enzyme, dispersibility a me ka cohesiveness.

Hoʻohana ʻia ia ma ke ʻano he mānoanoa, dispersant a me ka stabilizer i ka ʻoihana pena, a loaʻa ka hoʻohālikelike maikaʻi i ka wai a i ʻole nā ​​mea hoʻoheheʻe organik. E like me ka mea wehe pena. Hoʻohana ʻia ia ma ke ʻano he mānoanoa, dispersant a me ka stabilizer i ka ʻoihana inika, a loaʻa ka hoʻohālikelike maikaʻi i ka wai a i ʻole nā ​​​​mea hoʻoheheʻe organik. Hoʻohana nui ʻia kēia huahana i ka ʻili, nā huahana pepa, ka mālama ʻana i nā huaʻai a me nā mea kanu a me nā ʻoihana textile
