HPMC a me HEMC ma ke kahua kūkulu

He kuleana like ko HPMC a me HEMC i nā mea hana. Hiki ke hoʻohana ʻia e like me ka dispersant, ka mea hoʻopaʻa wai, ka mānoanoa a me ka binder, a me nā mea ʻē aʻe. Hoʻohana ʻia ia i loko o ka pahu sima e hoʻonui ai i kona adhesion, workability, hoʻemi i ka flocculation, hoʻomaikaʻi i ka viscosity a me ka shrinkage, a me ka mālama ʻana i ka wai, e hoʻemi i ka nalowale o ka wai ma luna o ka ʻili paʻa, hoʻomaikaʻi i ka ikaika, pale i nā māwae a me ka hoʻoheheʻe ʻana i nā paʻakai hiki ke hoʻoheheʻe ʻia i ka wai, etc. pono-leveling papahele mea, etc. Hiki ke hoʻohana 'ia e like me kiʻiʻoniʻoni-hana 'oihana, mānoanoa, emulsifier a me stabilizer i loko o emulsion coatings a me ka wai-hoʻoheheʻe resin coatings, e haawi ana i ke kiʻi maikaʻi abrasion kū'ē, uniformity a me ka adhesion, a me ka hoʻomaikaʻi 'ana i ka ili, paʻa i nāʻakika a me nā kumu a me ka launa pū me ka metala puaʻa. Ma muli o kona kūpaʻa mālama viscosity maikaʻi, kūpono loa ia e like me ka dispersant i nā uhi emulsified. Ma kahi huaʻōlelo, ʻoiai he liʻiliʻi ka nui o ka ʻōnaehana, he mea pono a hoʻohana nui ʻia.

Hoʻoholo ka mahana gel o cellulose ether i kona kūpaʻa wela i nā noi. ʻO ka mahana gel o HPMC maʻamau mai 60 ° C a 75 ° C, ma muli o ke ʻano, ka ʻike hui, nā kaʻina hana like ʻole o nā mea hana like ʻole, a me nā mea ʻē aʻe Ma muli o nā ʻano o ka hui HEMC, he kiʻekiʻe ka wela gel, maʻamau ma luna o 80 ° C. No laila, ʻoi aku ka kiʻekiʻe o kona kūpaʻa ma lalo o nā kūlana wela ma mua o ka HPMC. I ka hoʻomaʻamaʻa ʻana, ma lalo o ke kaiapuni hana wela loa i ke kauwela, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai o HEMC i loko o ka mortar hui pū me ka viscosity like a me ka dosing ma mua o HPMC.

ʻO ka nui o ka cellulose ether i loko o ka ʻoihana kūkulu hale o Kina, ʻo ia nō ka HPMC, no ka mea, ʻoi aku ka nui o nā ʻano a me nā kumukūʻai haʻahaʻa, a hiki ke koho manuahi ʻia ma ke kumukūʻai piha. Me ka hoʻomohala ʻana o ka mākeke kūkulu hale, ʻoi aku ka nui o ka hoʻonui ʻia ʻana o ka hana mechanized a me ka hoʻomaikaʻi ʻana i nā pono o ke kūkulu ʻana, e hoʻomau ka hoʻohana ʻana o HPMC i ke kahua kūkulu.
