4 Nīnau e pili ana iā HPMC

1. He aha nā mea hoʻohana nui o ka hydroxypropyl methylcellulose (HPMC)?
Hoʻohana nui ʻia ka HPMC i nā mea hana, nā uhi, nā resins synthetic, nā seramika, nā lāʻau lapaʻau, nā meaʻai, nā lole, nā mahiʻai, nā mea hoʻonaninani, ka paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i ka papa hana, ka papa meaʻai a me ka papa lāʻau lapaʻau e like me kona hoʻohana ʻana. I kēia manawa, aia ka hapa nui o ka hana hale Kina i ka pae kūkulu. Ma ka pae kūkulu, hoʻohana ʻia ka pauka putty i nā mea nui, ma kahi o 90% no ka pauka putty a ʻo kekahi no ka mortar sima a me ka paʻa tile.

2. He aha nā kumu o ka blistering i ka pauka putty i ka wā e hoʻohana ai i ka HPMC i ka pauka putty?
Hana ʻo HPMC ma ke ʻano he mānoanoa, mālama wai a me ka mea hana i nā pauka putty. ʻAʻole pili i kekahi pane.

Nā kumu o ka pehu: 1. Ka nui o ka wai. 2. ʻAʻole maloʻo ka papa lalo, e ʻoki wale i kahi papa ma ka papa luna, a maʻalahi hoʻi ka blistered.

3. Ehia na ano o ka hydroxypropyl methylcellulose (HPMC) i laila? He aha ka ʻokoʻa ma waena o lākou?
Hiki ke hoʻokaʻawale ʻia ka HPMC i hikiwawe a me ka wela. ʻO nā huahana hiki ke hoʻoheheʻe ʻia, hoʻopau koke a nalowale i ka wai i ka wai anuanu. I kēia manawa, ʻaʻohe viscosity o ka wai no ka mea ua hoʻopuehu wale ʻia ka HPMC i ka wai a ʻaʻole hoʻoheheʻe. Ma hope o 2 mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi gel viscous māmā. Hiki ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela. I ka hāʻule ʻana o ka mahana i kekahi mahana, ʻike ʻia ka viscosity a hiki i ka hana ʻana o kahi gel viscous akaka.

Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i nā pauka putty a me nā morta. I loko o nā glues wai a me nā pena, hiki mai ka caking a ʻaʻole hiki ke hoʻohana. ʻO ke ʻano koke ka nui o nā noi a hiki ke hoʻohana ʻia i nā pauka putty a me nā morta a me nā glues wai a me nā pena.

4. Pehea e ʻike maʻalahi ai ka maikaʻi o ka hydroxypropyl methylcellulose (HPMC)?
(1) Kaumaha kikoʻī: ʻO ke kiʻekiʻe o ka umekaumaha kikoʻī, ʻoi aku ka maikaʻi o ka maikaʻi.
(2) Keʻokeʻo: ʻO ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi. Koe wale no ka poe me na mea hookeokeo hou. Hiki i nā mea keʻokeʻo ke hoʻopili i ka maikaʻi.
(3) Fineness: ʻO ka ʻoi aku ka maikaʻi o ka maikaʻi, ʻoi aku ka maikaʻi o ka maikaʻi. ʻO ka maikaʻi o kā mākou HPMC maʻamau he 80 mesh a me 100 mesh, loaʻa pū kekahi 120 mesh.
(4) Ka lawe ʻana: E hoʻokomo i ka HPMC i loko o ka wai e hana i kahi gel ʻalohilohi a nānā i kāna transmittance. ʻO ka nui o ka transmittance, ʻoi aku ka liʻiliʻi o ka mea hiki ʻole ke hoʻoheheʻe. ʻOi aku ka maikaʻi o ka neʻe ʻana o nā reactors vertical a ʻoi aku ka maikaʻi o nā reactors horizontal, akā ʻaʻole ia he manaʻo ʻoi aku ka maikaʻi o ka hana ʻana o nā reactors vertical ma mua o nā ʻano hana ʻē aʻe. Nui nā kumu e hoʻoholo ai i ka maikaʻi o ka huahana i nā reactors horizontal, he kiʻekiʻe ka hydroxypropyl content a me ka hydroxypropyl content kiʻekiʻe, ʻoi aku ka maikaʻi no ka mālama ʻana i ka wai.
