ʻO ke ʻano maʻalahi o ka ʻike ʻana o ka hydroxypropyl methylcellulose

Hoʻohana nui ʻia ka Cellulose i ka petrochemical, ka lāʻau lapaʻau, ka hana pepa, nā mea hoʻonani, nā mea kūkulu hale, a me nā mea ʻē aʻe. He mea hoʻohui maʻalahi loa ia, a he ʻokoʻa nā koi hana no nā huahana cellulose no nā hoʻohana like ʻole.

Ke hoʻolauna nui nei kēia ʻatikala i ka hoʻohana a me ke ʻano ʻike maikaʻi o HPMC (hydroxypropyl methylcellulose ether), kahi ʻano cellulose i hoʻohana pinepine ʻia i ka pauka putty maʻamau.

Hoʻohana ʻo HPMC i ka pulupulu i hoʻomaʻemaʻe ʻia ma ke ʻano he mea maka nui. Loaʻa iā ia ka hana maikaʻi, ke kumukūʻai kiʻekiʻe a me ke kūpaʻa alkali maikaʻi. He kūpono ia no ka putty wai maʻamau a me ka mortar polymer i hana ʻia me ka sima, ka lime calcium a me nā mea alkaline ikaika ʻē aʻe. ʻO ka pae viscosity he 40,000-200000S.

Eia kekahi mau ʻano hana no ka hoʻāʻo ʻana i ka maikaʻi o ka hydroxypropyl methylcellulose i hōʻuluʻulu ʻia e Xiaobian no ʻoe. E hele mai e aʻo me Xiaobian~

1. Keʻokeʻo:

ʻOiaʻiʻo, ʻo ke kumu hoʻoholo i ka hoʻoholo ʻana i ka maikaʻi o ka hydroxypropyl methylcellulose ʻaʻole hiki ke keʻokeʻo wale nō. E hoʻohui kekahi mau mea hana i nā mea hoʻokeʻokeʻo i ke kaʻina hana, i kēia hihia, ʻaʻole hiki ke hoʻoholo ʻia ke ʻano, akā maikaʻi maoli ke keʻokeʻo o ka hydroxypropyl methylcellulose kiʻekiʻe.

2. Maikaʻi:

ʻO ka maʻamau, he 80 mesh, 100 mesh a me 120 mesh ka maikaʻi o ka Hydroxypropyl methylcellulose. He maikaʻi loa ka maikaʻi o nā ʻāpana, a maikaʻi nō hoʻi ka solubility a me ka paʻa ʻana o ka wai. He hydroxypropyl methylcellulose kiʻekiʻe kēia.

3. Ka hoʻoili ʻana o ka mālamalama:

E hoʻokomo i ka hydroxypropyl methylcellulose i loko o ka wai a hoʻoheheʻe iā ia i loko o ka wai no kekahi manawa e nānā i ka viscosity a me ka transparency. Ma hope o ka hoʻokumu ʻia ʻana o ka gel, e nānā i kona transmittance māmā, ʻoi aku ka maikaʻi o ka transmittance māmā, ʻoi aku ka kiʻekiʻe o ka mea insoluble a me ka maʻemaʻe.

4. Ke kaumaha kikoʻī:

ʻOi aku ka maikaʻi o ke kaumaha kikoʻī, no ka mea, ʻoi aku ke kaumaha o ke kaumaha kikoʻī, ʻoi aku ke kiʻekiʻe o ka nui o ka hydroxypropyl methyl i loko, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.
