HPMC Skim Coating Thickener

ʻO ka uhi ʻana o Skim kahi ala kaulana no ka loaʻa ʻana o kahi maʻemaʻe, ma luna o nā paia a me nā kaupaku. Hoʻopili ʻia ka ʻenehana i ka hoʻopili ʻana i kahi ʻāpana lahilahi o ka mortar a i ʻole ka stucco i kahi ʻili ʻāʻī a i ʻole ʻole e hana i kahi pae pae no ka pena a i ʻole ka wallpaper. ʻO ka HPMC a i ʻole ka hydroxypropyl methylcellulose kahi mānoanoa maʻamau no ka hui ʻana o ka ʻili lahilahi. E nānā pono kākou i nā pono o ka HPMC ma nā ʻāpana lahilahi.

ʻO ka mua, ʻo ka HPMC kahi mānoanoa maikaʻi loa no ka putty no ka mea hiki ke hoʻoheheʻe ʻia i ka wai a maʻalahi hoʻi e hui. ʻAʻole like me nā mea mānoanoa ʻē aʻe e like me ka starch tapioka a i ʻole ka palaoa palaoa, hoʻoheheʻe ʻia ʻo HPMC i ka wai, e maʻalahi ai ka loaʻa ʻana o kahi ʻano like ʻole i ka hui ʻana o ka uhi ʻana. Eia kekahi, he hoʻopili maikaʻi loa ka HPMC, e kōkua ana i ka putty e hoʻopili i ka substrate a pale i ka haki.

ʻO kekahi pōmaikaʻi koʻikoʻi o ka hoʻohana ʻana i ka HPMC i nā hui ʻana o ka putty coating ʻo ia ka hiki ke hoʻomaikaʻi i ka hana a me ke kahe. Ma muli o ka mānoanoa ʻana o ka HPMC i ka hui ʻana, hāʻawi ia i ka plasterer i ka manawa hou e hana ai ma nā papa o ka putty ma mua o kona kau ʻana. Ma ka huli ʻana, ʻae kēia i kahi noi ʻoi aku ka maʻalahi. Eia kekahi, hoʻonui ka HPMC i nā waiwai pae o ka putty, e ʻae iā ia i ka pae ponoʻī a hoʻopiha i nā hemahema liʻiliʻi i ka substrate.

ʻO ka HPMC kekahi koho pili i ke kaiapuni no ka hoʻokumu ʻana i ka papa lahilahi. Ma ke ʻano he huahana cellulose, biodegradable a ʻaʻohe mea ʻawaʻawa. ʻO ia hoʻi, ʻaʻohe hopena maikaʻi o ka HPMC i ke kaiapuni a i ʻole ke olakino kanaka. Hoʻohui hou, hoʻomaikaʻi ʻo HPMC i ka hoʻomau ʻana ma o ka hōʻemi ʻana i ka ʻōpala a me ka pale ʻana i ka hoʻoponopono nui ʻana a i ʻole ke pani hou ʻana.

ʻO ka mea hope loa, ʻo ka HPMC ke kumu kūʻai a loaʻa ākea. Hoʻokumu nui ʻia a kūʻai ʻia ma ka mākeke honua, hiki ke loaʻa i nā mea hana a me nā mea hoʻohana hope. He lōʻihi ke ola o ka HPMC, ʻo ia hoʻi, hiki ke mālama ʻia no ka manawa lōʻihi me ka nalowale ʻole o ka maikaʻi a i ʻole ka maikaʻi.

I ka hopena, ʻo HPMC kahi mānoanoa maikaʻi loa no ka hui ʻana o ka putty coating. Hāʻawi ia i kahi ākea o nā pono e like me ka hoʻomaikaʻi ʻana i ka processability, kahe, pae a me ka adhesion. Eia kekahi, he mea pili i ke kaiapuni, kūpono ke kumu kūʻai a loaʻa i ka nui o nā noi. No laila, he koho kaulana ʻo HPMC no ka poʻe novice a me ka poʻe loea e ʻimi ana e hoʻokō i kahi maʻemaʻe, ma luna o nā paia a me nā kaupaku.
