Pehea e ʻike ai i ka maikaʻi o ka hydroxypropyl methyl?

01. ʻO ka ʻokoʻa ma waena o ka hydroxypropyl methyl hoʻopunipuni a me ka hydroxypropyl methyl kiʻekiʻe

ʻAno: ʻIke ʻia ka palaoa maʻemaʻe HPCM he like loa, ma waena o 0.3 a me 0.4 g/ml. Hoʻopaʻa ʻo Amylum i ka palaoa no laila he wai ka HPCM a emi iki ke kaumaha ma mua o nā detoxifiers maʻamau.

Nā Kūlana: starch piha i ka starch, hpm powder, fiber ma lalo o ka microscope a i ʻole ke aniani hoʻonui, HPCM kahi ʻano starch hiki ke hoʻomalu i ka starch a i ʻole starch a me nā lentil.

ʻAla: ʻAʻole hiki i ka hydroxypropyl methylcellulose HPMC ke honi i ka ammonia, starch a me ka waiʻona; hiki i ka hydroxypropyl methylcellulose HPMC i hoʻohuihui ʻia ke honi i nā ʻano ʻala like ʻole, ʻoiai inā he ʻono ʻole, e nāwaliwali ia.

Wai hoʻonā: maʻemaʻe, HPMC methylcellulose demethoxypropyl brinzolamide wai hoʻonā he moakāka, māmā ka paʻa wai ʻana he ≥ 97%; ʻoi aku ka turbid o ka cellulose hydrolyzed diluted-diluted HPMC hydrolyzed cellulose, ʻaneʻane hiki ʻole i ka 80% ka paʻa wai.

02. ʻO ka mālama ʻana i ka methyl cellulose i ka mahana kiʻekiʻe he mea nui ia e hoʻoholo ai i ka maikaʻi o ka methyl cellulose ether. ʻO nā mea e like me ka mahana o ka ea, ka mahana o ka ea a me ka wikiwiki o ka makani e hoʻopilikia i ka volatility o ka slurry sima a me nā huahana gypsum. No laila, me ka hoʻohui ʻana i ka nui like o nā huahana HPMC i nā kau like ʻole, aia kekahi mau ʻokoʻa i ka pono mālama wai. I ke kaʻina hana kikoʻī, hiki ke hoʻoponopono ʻia ka hopena o ka moisturizing serosa ma ka hōʻemi ʻana i ka nui o ka HPMC i hoʻohui ʻia. Hiki i ka hydroxypropyl methylcellulose HPMC kiʻekiʻe ke hoʻoponopono pono i ka pilikia o ka paʻa ʻana o ka wai wela kiʻekiʻe.

Hiki ke hoʻokaʻawale like ʻia ka methyl cellulose kiʻekiʻe a me ka maikaʻi i loko o ka sima sima a me nā huahana palaki, e hana ana i kahi kiʻiʻoniʻoni paʻa, kahi e hoʻokuʻu mālie ʻia mai ka papa kumu a hana i kahi hopena hydrophilic me nā mea curling inorganic, no laila e hōʻoiaʻiʻo ana i ka ikaika a me ka paʻakikī. He qualitative a like ka HPMC cellulose methyl propoxylate, a ʻo ka oxygen o ka ethyl bromide a me nā hui propionic acid ma ke kaulahao cellulose molecular he like, kahi e hoʻomaikaʻi ai i ka oxygen a me ka hydrogen bonding o kēlā me kēia atom koʻikoʻi o ka hydroxyl a me ka ether. Hiki i ka wai haʻahaʻa ke hoʻololi i ka wai manuahi i loko o ka wai mālama ʻili, no laila e kāohi pono ana i ka mahu wai, e hoʻoulu ai i ka wela, a me ka makū wai kiʻekiʻe.

Ma muli o ke kūkulu ʻana i ke kauwela me ke ana wela kiʻekiʻe, i mea e hoʻokō ai i ka hopena o ka mālama wai, pono e hoʻohui i nā huahana HPMC kiʻekiʻe e like me ke ʻano hana, a i ʻole e hoʻopilikia ia e like me ka maloʻo nui ʻana, ka ikaika haʻahaʻa, ka haki ʻana, ka haʻalulu palaualelo a me ka hāʻule ʻana, a hoʻonui i ka paʻakikī o ke kūkulu ʻana no nā limahana. ʻOiai e hoʻohaʻahaʻa ana i ka mahana, hiki ke hoʻemi mālie i ka nui o ka HPMC i hoʻohui ʻia a loaʻa ka hopena mālama wai like.
