Hoʻohana nui ʻia ʻo Cellulose i ka petrochemical, lāʻau lapaʻau, hana pepa, nā mea hoʻonaninani, nā mea kūkulu hale, a me nā mea ʻē aʻe.
Hōʻike nui kēia ʻatikala i ka hoʻohana ʻana a me ke ala ʻike maikaʻi o HPMC (hydroxypropyl methylcellulose ether), kahi ʻano cellulose i hoʻohana mau ʻia i ka pauka putty maʻamau.
Hoʻohana ʻo HPMC i ka pulupulu i hoʻomaʻemaʻe ʻia ma ke ʻano he kumu nui.Loaʻa iā ia ka hana maikaʻi, ke kumukūʻai kiʻekiʻe a me ke kūpaʻa alkali maikaʻi.He kūpono ia no ka putty pale wai a me ka mortar polymer i hana ʻia me ka sima, ka lime calcium a me nā mea alkaline ikaika ʻē aʻe.ʻO ka laulā viscosity he 40,000-200000S.
Eia kekahi mau ala e hoʻāʻo ai i ka maikaʻi o ka hydroxypropyl methylcellulose i hōʻuluʻulu ʻia e Xiaobian no ʻoe.E hele mai e aʻo me Xiaobian~
1. Keokeo:
ʻOiaʻiʻo, ʻo ka mea 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 keʻokeʻo keʻokeʻo i ke kaʻina hana, i kēia hihia, ʻaʻole hiki ke hoʻokolokolo ʻia ka maikaʻi, akā maikaʻi maoli ke keʻokeʻo o ka hydroxypropyl methylcellulose kiʻekiʻe.
2. Ka maikaʻi:
ʻO ka hydroxypropyl methylcellulose ka mea maʻamau he 80 mesh, 100 mesh a me 120 mesh.Maikaʻi loa ka maikaʻi o nā ʻāpana, a maikaʻi hoʻi ka solubility a me ka paʻa ʻana o ka wai.He hydroxypropyl methylcellulose kiʻekiʻe kēia.
3. Ka hoʻouna māmā:
E hoʻokomo i ka hydroxypropyl methylcellulose i loko o ka wai a hoʻoheheʻe i loko o ka wai no kekahi manawa e nānā i ka viscosity a me ka ʻike.Ma hope o ka hana ʻana o ka gel, e nānā i kāna transmittance māmā, ʻoi aku ka maikaʻi o ka transmittance māmā, ʻoi aku ka kiʻekiʻe o ka mea insoluble a me ka maʻemaʻe.
4. Kaumaha kikoʻī:
ʻO ka nui o ka'umekaumaha kiko'ī,ʻoi aku ka maikaʻi, no ka mea,ʻoi aku ka nui o ka'umekaumaha kiko'ī,ʻoi aku ka kiʻekiʻe o ka hydroxypropyl methyl i loko,ʻoi aku ka maikaʻi o ka paʻaʻana o ka wai.
