He aha nā mea e hoʻohuli ai i ka maʻemaʻe o ka hydroxypropyl methyl cellulose?

I loko o ka hale insulation mortar a me ka pauka putty, ka nui o ka hydroxypropyl methylcellulose maʻemaʻe e pili pono i ka maikaʻi o ka hana ʻenekinia, no laila he aha nā mea e pili ana i ka maʻemaʻe o ka hydroxypropyl methylcellulose? E kōkua iā ʻoe e pane i kēia nīnau i kēia lā.

I ke kaʻina hana o ka hydroxypropyl methylcellulose, ʻo ka oxygen e koe ana i loko o ka ʻeke pane e alakaʻi i ka degradation o hydroxypropyl methylcellulose a hoʻemi i ke kaumaha mole. Eia nō naʻe, ua kaupalena ʻia ke koena oxygen, no laila ʻaʻole paʻakikī ke hoʻopili hou i nā molekala i haki. ʻO ka nui saturation rate a me ka hydroxypropyl content he pilina nui, makemake wale kekahi mau hale hana e hoʻemi i ke kumukūʻai a me ke kumukūʻai, ʻaʻole makemake e hoʻomaikaʻi i ka ʻike o ka hydroxypropyl, no laila ʻaʻole hiki i ka maikaʻi ke hiki i ke kiʻekiʻe o nā huahana like ʻole.

ʻO ka nui o ka mālama ʻana i ka wai o ka hydroxypropyl methylcellulose a me ka hydroxypropyl he pilina nui nō hoʻi, a no ke kaʻina hana holoʻokoʻa, hoʻoholo pū ka hydroxypropyl methylcellulose i ka nui o ka paʻa wai o ka hydroxypropyl methylcellulose. ʻO ka hopena o ka alkalization, ka ratio o ka chloromethane i ka propylene oxide, ka ʻike o ka alkali a me ka ratio o ka wai i ka pulupulu hoʻomaʻemaʻe ʻia nā mea a pau e hoʻoholo ai i ka hana o ka huahana.

ʻO ka maikaʻi o nā mea maka, ka hopena alkalization, ka hoʻokele lākiō kaʻina, ka lākiō solvent a me ka hopena neutralization, nā mea a pau e hoʻoholo i ka maikaʻi o ka hydroxypropyl methyl cellulose, kekahi hydroxypropyl methyl cellulose i hana ʻia e hoʻoheheʻe ʻia ma hope e like me ka waiū he ao loa, keʻokeʻo milky kekahi, melemele kekahi, kekahi. maopopo a maopopo. Inā makemake ʻoe e hoʻoponopono, e hoʻoponopono mai nā helu i luna. I kekahi manawa hiki i ka acetic acid ke hoʻopilikia koʻikoʻi i ka transmittance, ʻoi aku ka maikaʻi o ka acetic acid ma hope o ka dilution, ʻo ka hopena nui a i ʻole ka hoʻoulu ʻana o ka hopena he ʻano like, paʻa ka pae ʻōnaehana (kekahi mau mea, ʻaʻole paʻa ka ʻike, e like me ka hoʻihoʻi ʻana o ka solvent), ʻoiaʻiʻo, nui nā kumu i pili. Me ka paʻa o nā mea hana a me ka hana o nā mea hana i hoʻomaʻamaʻa ʻia, pono e paʻa loa nā huahana i hana ʻia. ʻAʻole pono ka transmittance ma mua o ± 2%, a pono e hoʻomalu maikaʻi ʻia ka hoʻololi like ʻana o ka hui pani. ʻO ka hoʻololi like ʻana, pono e maikaʻi ka transmittance.

No laila, hoʻoholo ʻia ka maikaʻi o ka huahana e nā mea maka, ʻenehana hana, a me nā mea ʻē aʻe. ʻO ka mana koʻikoʻi wale nō mai kahi hopena a hiki i ka hopena hiki ke hana i nā huahana me ka maikaʻi paʻa.
