Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl Methyl Cellulose (HEMC)

ʻO ka Hydroxyethyl methyl cellulose (HEMC) he polymer hiki ke hoʻoheheʻe wai i loaʻa mai ka cellulose. He mea non-ionic, non-toxic, a non-flammable pūhui i hoʻohana nui ʻia i nā ʻano hana ʻoihana a me nā mea kūʻai aku. He mea waiwai ʻo HEMC no kona hiki ke hana ma ke ʻano he mānoanoa, hoʻopili, a me ka hoʻololi rheology i nā huahana he nui.

Hana ʻia ʻo HEMC e ka hoʻololi kemika i nā fiber cellulose maoli. Ma kēia kaʻina hana, mālama ʻia nā fiber cellulose me ka sodium hydroxide e hana i ka cellulose alkali. Hoʻohui ʻia ka Ethylene oxide i ka hui ʻana, e hana pū me ka cellulose e hana i ka hydroxyethyl cellulose. ʻO ka hope, hoʻohui ʻia ka methyl chloride i ka hui ʻana e hana i ka HEMC.

Hoʻohana ʻia ʻo HEMC ma kahi ākea o nā noi, me ke kūkulu ʻana, ka meaʻai, ka mālama pilikino, a me nā lāʻau lapaʻau. ʻO kekahi o ka hoʻohana mua ʻana o HEMC i ke kūkulu ʻana, kahi e hoʻohana ʻia ai i nā huahana like ʻole e like me nā morta maloʻo maloʻo, putties, tile adhesives, a me nā huahana gypsum.

I loko o nā morta maloʻo maloʻo, hoʻohana ʻia ʻo HEMC ma ke ʻano he mānoanoa, mea hoʻopili, a me ka mea paʻa wai. Kōkua ia i ka hoʻomaikaʻi ʻana i ka hana o ka mortar a hiki ke hoʻomalu maikaʻi i ka ʻike wai. He mea koʻikoʻi kēia no ka mea e pili ana ka wai o ka mortar i kona kūlike, ka manawa hoʻonohonoho, a me ka ikaika hope.

I nā putties, hoʻohana nui ʻia ʻo HEMC ma ke ʻano he mānoanoa a me ka mea hoʻopili. ʻO ka hoʻohui ʻana o HEMC i ka hui ʻana e kōkua i ka hoʻomaikaʻi ʻana i ka hana o ka putty a hiki i ka mana maikaʻi o ka ʻike wai. Kōkua ʻo HEMC i ka pale ʻana i ka hoʻokaʻawale ʻana o nā ʻāpana like ʻole i ka hoʻokumu ʻana i ka putty, a hoʻomaikaʻi ia i ka hoʻopili ʻana o ka putty i nā substrates.

I loko o ka tile adhesives, hoʻohana mua ʻia ʻo HEMC ma ke ʻano he mea mālama wai. ʻO ka hoʻohui ʻana o HEMC i ka hui ʻana e kōkua i ka hoʻomaikaʻi ʻana i ka hana o ka mea hoʻopili a hiki ke hoʻomalu maikaʻi i ka ʻike wai. Kōkua ʻo HEMC i ka pale ʻana i ka hoʻokaʻawale ʻana o nā ʻāpana like ʻole i ka hoʻopili hoʻopili, a hoʻomaikaʻi ia i ka hoʻopili ʻana o ka adhesive i nā substrates.

I nā huahana gypsum, hoʻohana ʻia ʻo HEMC ma ke ʻano he mānoanoa, hoʻopaʻa, a me ka mea mālama wai. Kōkua ia i ka hoʻomaikaʻi ʻana i ka hana o ka huahana gypsum a hiki ke hoʻomalu maikaʻi i ka ʻike wai. He mea nui kēia no ka mea e pili ana ka wai o ka huahana gypsum i kona manawa hoʻonohonoho a me ka ikaika hope.

I nā huahana meaʻai, hoʻohana pinepine ʻia ʻo HEMC ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier. Hoʻohana ʻia ia i loko o nā ʻano meaʻai like ʻole, me nā meaʻai, nā lole, a me nā huahana waiū. He mea nui ka HEMC no kona hiki ke hoʻomaikaʻi i ke ʻano a me ke kūpaʻa o kēia mau huahana.

I nā huahana mālama pilikino, hoʻohana ʻia ʻo HEMC ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier. Hoʻohana ʻia ia i nā ʻano mea like ʻole o nā huahana mālama pilikino, me nā shampoos, conditioners, a me nā lotions. He mea nui ka HEMC no kona hiki ke hoʻomaikaʻi i ke ʻano a me ke kūpaʻa o kēia mau huahana.

I nā lāʻau lapaʻau, hoʻohana ʻia ʻo HEMC ma ke ʻano he mea hoʻopaʻa a me ka disintegrant. Hoʻohana ʻia ia i loko o ka papa papa e hoʻomaikaʻi ai i ka ikaika mechanical o ka papa a kōkua i ka hoʻokaʻawale ʻana a me ka hemo ʻana o ka papa i loko o ke kino.
