He aha nā mea e pili ana i ka maʻemaʻe o ka hydroxypropyl methylcellulose?

ʻO ka maʻemaʻe o ka hydroxypropyl methylcellulose i ke kūkulu ʻana i ka mortar insulation a me ka pauka putty 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 mākou iā ʻoe e pane i kēia nīnau i kēia lā.

I ke kaʻina hana o ka hydroxypropyl methylcellulose, ke koena oxygen i loko o ka reactor e hoʻohaʻahaʻa i ka hydroxypropyl methylcellulose a hoʻemi i ke kaumaha mole, akā ua kaupalena ʻia ke koena o ka oxygen, ʻoiai ʻaʻole paʻakikī loa ka hoʻopili hou ʻana i nā molekala haki. ʻO ka nui o ka nui o ka saturation wai nui e pili ana i ka ʻike o ka hydroxypropyl. Makemake wale kekahi mau hale hana e hoʻemi i ke kumukūʻai a me ke kumukūʻai, akā ʻaʻole makemake e hoʻonui i ka ʻike o ka hydroxypropyl, no laila ʻaʻole hiki i ka maikaʻi ke hiki i ke kiʻekiʻe o nā huahana like ʻole.

He pilina nui ka wai o ka hydroxypropyl methylcellulose me ka hydroxypropyl, a no ke kaʻina hana holoʻokoʻa, hoʻoholo pū ka hydroxypropyl i ka pae paʻa wai o ka hydroxypropyl methylcellulose. ʻO ka hopena o ka alkalization, ka lakio o ka methyl chloride a me ka propylene oxide, ka neʻe ʻana o ka alkali a me ka ratio o ka wai i ka pulu i hoʻomaʻemaʻe ʻia e hoʻoholo i ka hana o ka huahana.

ʻO ka maikaʻi o nā mea maka, ka hopena o ka alkalization, ka mana o ka ratio o ke kaʻina hana, ka ratio o nā solvents a me ka hopena o ka neutralization e hoʻoholo i ka maikaʻi o ka hydroxypropyl methylcellulose, a ua hana ʻia kekahi hydroxypropyl methylcellulose e hoʻoheheʻe ʻia Ma hope, ua pōʻeleʻele e like me ka hoʻohui ʻana. waiu, he waiu keokeo kekahi, he melemele kekahi, a he moakaka kekahi. 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 māmā. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i ka acetic acid ma hope o ka dilution. ʻO ka mana nui loa, ʻo ia ka hoʻoulu ʻia ʻana o ka hopena a paʻa paha ka ratio o ka ʻōnaehana (he makū kekahi mau mea a paʻa ʻole ka ʻike, e like me nā mea hoʻoheheʻe hou). ʻOiaʻiʻo, nui nā kumu e pāʻani nei. Me ka paʻa o nā mea hana a me ka hana o nā mea hana i hoʻomaʻamaʻa maikaʻi ʻia, pono e kūpaʻa nā huahana i hana ʻia. ʻAʻole e ʻoi aku ka māmā o ka lawe ʻana i ka ± 2%, a pono e hoʻomalu maikaʻi ʻia ka hoʻololi like ʻana o nā hui pani. Ma kahi o ka like ʻole, ʻoi aku ka maikaʻi o ka transmittance māmā.

No laila, hoʻoholo ʻia ka maikaʻi o ka huahana maikaʻi e nā kumu he nui e like me nā mea maka, ka ʻenehana hana, a me nā mea ʻē aʻe.
