hoʻolauna:
ʻO ka Methylhydroxyethylcellulose (MHEC) he cellulose ether maʻamau i hoʻohana nui ʻia i nā ʻoihana like ʻole ma muli o kāna paʻa wai maikaʻi a me nā waiwai paʻa. Loaʻa ka MHEC mai ka cellulose kūlohelohe a ua loaʻa i nā noi i ke kūkulu ʻana, nā lāʻau lapaʻau, nā meaʻai a me nā mea hoʻonaninani.
ʻO ke kinona a me nā waiwai:
ʻO MHEC kahi methyl-substituted hydroxyethylcellulose derivative me kahi ʻano molekala kū hoʻokahi. Hāʻawi ka iwi kuamoʻo cellulose i ka biodegradability inherent a me ka hoʻopili ʻana i ke kaiapuni, e hoʻolilo iā MHEC ke koho mua no nā noi he nui. Hoʻonui ka hui hydroxyethyl a me methyl i kona solubility a hoʻololi i kāna mau waiwai kino a me ke kemika, e hāʻawi ana i nā ʻano hana like ʻole.
ʻO ka hana mālama wai:
ʻO kekahi o nā hiʻohiʻona nui o ka MHEC ʻo ia kona mana mālama wai maikaʻi loa. I nā mea hana e like me nā morta a me nā huahana sima, hana ʻo MHEC ma ke ʻano he mea mālama wai, pale i ka nalowale wikiwiki o ka wai i ka wā o ka hoʻōla ʻana. Pono kēia no ka mālama ʻana i ke kaʻina hana maikaʻi, hoʻomaikaʻi i ka adhesion a hoʻonui i ka hana holoʻokoʻa o ka mea.
Loaʻa ka MHEC i ka mālama ʻana i ka wai ma o kekahi mau hana:
Hydrophilicity: ʻO ke ʻano hydrophilic o MHEC hiki iā ia ke komo a mālama i nā molekole wai. ʻO ka iwi kuamoʻo cellulose, me nā pūʻulu hydroxyethyl a me methyl, hoʻokumu i kahi hale hiki ke mālama i ka wai i loko o kāna matrix.
Nā waiwai hana kiʻiʻoniʻoni: Hiki i ka MHEC ke hana i kahi kiʻiʻoniʻoni lahilahi a maʻalahi ke hoʻopuehu ʻia i ka wai. Ke hana nei ke kiʻiʻoniʻoni ma ke ʻano he pale, e hoʻemi ana i ka hoʻoheheʻe ʻana o ka wai a hāʻawi i kahi papa pale e mālama ai i ka makū i loko o ka mea.
Ka hopena mānoanoa: No ka pehu ʻana o MHEC i ka wai, hōʻike ia i kahi hopena mānoanoa. Hāʻawi kēia hoʻonui viscosity i ka mālama ʻana i ka wai maikaʻi, e pale ana i ka wai mai ka hoʻokaʻawale ʻana mai ka mea a me ka mālama ʻana i kahi hui homogeneous.
Nā noi i ke kūkulu ʻana:
Ke hilinaʻi nui nei ka ʻoihana kūkulu i ka MHEC no kāna mau waiwai mālama wai. Hoʻomaikaʻi ʻo MHEC i ka mortar, grout a me nā mea cementitious ʻē aʻe ma o ka hoʻomaikaʻi ʻana i ka hana, hoʻemi ʻana i ka haki ʻana a me ka hoʻomaikaʻi ʻana i ka pili. Hoʻohui hou, hoʻomaʻamaʻa ʻo MHEC i ka pahū ʻana a me ka pīpī ʻana i nā mea kūkulu hale, e lilo ia i mea hoʻohui waiwai i nā hana kūkulu hou.
Nā waiwai hoʻopili:
Ma waho aʻe o ka hoʻopaʻa ʻana i ka wai, he kuleana koʻikoʻi ka MHEC i ka hoʻomaikaʻi ʻana i ka adhesion ma nā ʻano noi like ʻole. He waiwai nui kona mau waiwai i loko o nā ʻoihana ma lalo nei:
Pākuʻi Tile: Hoʻohana pinepine ʻia ʻo MHEC i nā tile adhesives e hoʻonui ai i ka ikaika paʻa ma waena o ka tile a me ka substrate. Hoʻokumu ia i nā kiʻiʻoniʻoni maʻalahi a hoʻomaikaʻi i ka hana, e hōʻoia i ka paʻa paʻa a lōʻihi.
Kākoʻo Kiʻi Paʻi: Ma ka hana ʻana i ka paʻi pepa pepa, kōkua ʻo MHEC i ka hoʻopaʻa ʻana i ka pepa pepa i ka paia. Kāohi ia i ka paʻi mai ka maloʻo ʻana ma mua o ka manawa a hoʻoikaika i kahi paʻa ikaika a lōʻihi.
Nā Hui Hui: Hoʻohana ʻia ka MHEC i nā pūhui hui ma muli o kāna mau mea paʻa a mānoanoa. Kōkua ia i ka hoʻokō ʻana i ka hoʻopau ʻoluʻolu a paʻa i nā noi drywall.
i ka hopena:
ʻO ka Methylhydroxyethylcellulose (MHEC) kahi etera cellulose faceted me ka paʻa wai maikaʻi a me nā waiwai pili. ʻO kona ʻano molecular kū hoʻokahi, hydrophilicity, hiki ke hana kiʻiʻoniʻoni a me ka hopena mānoanoa e hoʻohana nui ʻia i nā ʻoihana like ʻole. Mai nā mea kūkulu hale a hiki i nā lāʻau lapaʻau a me nā mea hoʻonaninani, hana koʻikoʻi ka MHEC i ka hoʻomaikaʻi ʻana i ka hana huahana a me ka hōʻoia ʻana i ka hana kūpono. Ke hoʻomau nei nā ʻoihana i ka ʻimi ʻana i nā hoʻonā kaiapuni a maikaʻi hoʻi, ke hoʻomau nei ka MHEC i kahi koho waiwai a hoʻomau no nā ʻano noi like ʻole.
