ʻO HPMC lāua ʻo HEMC ma ke kahua kūkulu hale

Loaʻa iā HPMC a me HEMC nā kuleana like i nā mea kūkulu hale. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻolaha, mea paʻa wai, mea hoʻomānoanoa a me ka mea hoʻopaʻa, a pēlā aku. Hoʻohana nui ʻia ia i ka sima mortar a me ke kālai ʻana o nā huahana gypsum. Hoʻohana ʻia ia i loko o ka sima mortar e hoʻonui i kona hoʻopili ʻana, ka hana, hoʻemi i ka flocculation, hoʻomaikaʻi i ka viscosity a me ka shrinkage, a me ka mālama ʻana i ka wai, hoʻemi i ka nalowale o ka wai ma luna o ka ʻili sima, hoʻomaikaʻi i ka ikaika, pale i nā māwae a me ka palaho o nā paʻakai wai-soluble, a pēlā aku. Hoʻohana nui ʻia ia i loko o ka plaster sima, gypsum plaster, nā huahana gypsum, masonry mortar, sheet caulking, caulking agent, tile adhesive, self-leveling floor material, a pēlā aku. Hiki ke hoʻohana ʻia ma ke ʻano he mea hana kiʻiʻoniʻoni, thickener, emulsifier a me stabilizer i nā uhi emulsion a me nā uhi resin wai-soluble, e hāʻawi ana i ka kiʻiʻoniʻoni i ka pale ʻana i ka abrasion, ka like a me ka hoʻopili ʻana, a me ka hoʻomaikaʻi ʻana i ka ʻili, ka paʻa i nā waikawa a me nā kumu a me ka hoʻohālikelike me nā pigments metala. Ma muli o kona paʻa maikaʻi o ka mālama ʻana i ka viscosity, kūpono loa ia ma ke ʻano he mea hoʻolaha i nā uhi emulsified. I kahi huaʻōlelo, ʻoiai he liʻiliʻi ka nui o ka ʻōnaehana, he mea pono loa ia a hoʻohana nui ʻia.

ʻO ka mahana gel o ka cellulose ether ke kumu o kona kūpaʻa wela i nā noi. ʻO ka mahana gel o HPMC maʻamau mai 60°C a 75°C, ma muli o ke ʻano, ka ʻike o ka hui, nā kaʻina hana like ʻole o nā mea hana like ʻole, a pēlā aku. Ma muli o nā ʻano o ka hui HEMC, he kiʻekiʻe kona mahana gel, ma mua o 80°C. No laila, ʻoi aku ke kiʻekiʻe o kona kūpaʻa ma lalo o nā kūlana wela kiʻekiʻe ma mua o ka HPMC. I ka hana maoli, ma lalo o ke kaiapuni kūkulu wela loa i ke kauwela, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai o HEMC i loko o ka mortar hui pulu me ka viscosity like a me ka dosing ma mua o HPMC.

ʻO ka cellulose ether nui ma ka ʻoihana kūkulu hale o Kina ʻo HPMC nō naʻe, no ka mea, he nui aku nā ʻano a me nā kumukūʻai haʻahaʻa, a hiki ke koho manuahi ʻia ma ke kumukūʻai piha. Me ka hoʻomohala ʻana o ka mākeke kūkulu hale, ʻoiai ka hoʻonui ʻia ʻana o ke kūkulu mīkini a me ka hoʻomaikaʻi ʻana i nā koi maikaʻi o ke kūkulu ʻana, e hoʻomau ka hoʻonui ʻia ʻana o ka hoʻohana ʻana o HPMC ma ke kahua kūkulu.
