01. ʻO ka ʻokoʻa ma waena o ka hydroxypropyl methyl hoʻopunipuni a me ka hydroxypropyl methyl kiʻekiʻe
ʻAno: ʻIke ʻia ʻo ka mākiko maʻemaʻe HPCM like ʻole, ma waena o 0.3 a me 0.4 g/ml. Hoʻopaʻa ʻia ʻo Amylum i ka starch no laila he wai ka HPCM a emi ke kaumaha ma mua o nā detoxifier maʻamau.
Nā kūlana: starch piha i ka starch, ka pauka hpm, ka 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 lelo.
ʻAla: ʻAʻole hiki i ka HPMC hydroxypropyl methylcellulose maʻemaʻe ke honi i ka amonia, ka mākiko a me ka waiʻona; Hiki ke honi ka HPMC hydroxypropyl methylcellulose adulterated i nā ʻano ʻala a pau, ʻoiai inā ʻaʻohe ʻono, ʻoi aku ka nāwaliwali o Shen.
ʻO ka hoʻonā wai: maʻemaʻe, HPMC methylcellulose demethoxypropyl brinzolamide aqueous solution maʻemaʻe, māmā ka paʻa wai ≥ 97%; diluted hydrolyzed cellulose-diluted HPMC hydrolyzed cellulose ua oi turbid, ka wai paʻa pākēneki hiki hiki 80% .
02. ʻO ka mālamaʻana i ka methyl cellulose i ka wela kiʻekiʻe he mea nui ia e hoʻoholo ai i ka maikaʻi o ka methyl cellulose ether. ʻO nā mea e like me ke ea wela, ka ea wela a me ka wikiwiki o ka makani e pili ana i ka volatility o ka slurry cement a me nā huahana gypsum. No laila, ʻo 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. Ma ke kaʻina hana kūikawā, hiki ke hoʻoponopono ʻia ka hopena o ka moisturizing serosa ma ka hoʻemi ʻana i ka nui o ka HPMC i hoʻohui ʻia. Hiki i ka HPMC hydroxypropyl methylcellulose kiʻekiʻe ke hoʻoponopono i ka pilikia o ka mālama ʻana i ka wai wela.
Hiki ke hoʻokaʻawale maikaʻi ʻia ka methyl cellulose kiʻekiʻe i ka mortar sima a me nā huahana plastering, e hana ana i kahi kiʻiʻoniʻoni paʻa holoʻokoʻa, i hoʻokuʻu mālie ʻia mai ka papa kumu a hana i kahi hopena hydrophilic me nā mea curling inorganic, a laila e hōʻoia i ka ikaika a me ka paʻakikī. HPMC cellulose methyl propoxylate he qualitative a like, a me ka oxygen o ka ethyl bromide a me ka propionic acid pūʻulu ma ka molecular cellulose kaulahao, e hoʻomaikaʻi i ka oxygen a me ka hydrogen paʻa o kēlā me kēia kī atom o hydroxyl a me ka ether Hiki i ka wai haʻahaʻa ke hoʻololi i ka wai manuahi i loko. ka wai mālama ʻili, no laila e hoʻomalu pono i ka hoʻoheheʻe ʻana o ka wai, hoʻoulu i ka wela, a me ka wai kiʻekiʻe.
Ma muli o ke kiʻekiʻe o ke ana wela i ke kauwela, i mea e hoʻokō ai i ka hopena o ka mālama ʻana i ka wai, pono e hoʻohui i nā huahana HPMC kiʻekiʻe e like me ke ʻano, inā ʻaʻole ia e hoʻopilikia i nā pilikia e like me ka maloʻo nui, ka ikaika haʻahaʻa, ka haki ʻana, ka palaualelo. haʻalulu a haʻalele, a hoʻonui i ka paʻakikī o ke kūkulu ʻana no nā limahana. I ka hoʻohaʻahaʻa ʻana i ka mahana, hiki ke hoʻemi mālie i ka nui o ka HPMC i hoʻohui ʻia a loaʻa ka hopena mālama wai like.
