No ka mea ua like nā waiwai o ka hydroxypropyl methylcellulose me nā ethers hiki ke hoʻohana ʻia i ka emulsion coatings a me ka wai-soluble resin coating component e like me ka mea hana kiʻiʻoniʻoni, thickener, emulsifier a me stabilizer, a me nā mea ʻē aʻe. maikaʻi abrasion kū'ē. ʻO ka uhi like ʻana a me ka hoʻopili ʻana, a me ka hoʻomaikaʻi ʻana i ka ʻili o ka ʻili, kūpaʻa i nā waikawa a me nā kumu, a me ka launa pū me nā puaʻa metala.
No ka mea he kiʻekiʻe ka helu gel o ka HPMC ma mua o ka MC, ʻoi aku ka pale ʻana i ka hoʻouka ʻana i ka bacteria ma mua o nā eter cellulose ʻē aʻe, a no laila hiki ke hoʻohana ʻia ma ke ʻano he mānoanoa no nā uhi emulsion aqueous. Loaʻa i ka HPMC ka paʻa o ka mālama viscosity maikaʻi a me kona dispersibility maikaʻi loa, no laila kūpono kūpono ʻo HPMC ma ke ʻano he dispersant i nā uhi emulsion.
ʻO ka hoʻohana ʻana o ka hydroxypropyl methyl cellulose i ka ʻoihana uhi e like me kēia.
1.various viscosity HPMC hoʻonohonoho peʻa lole pale, kiʻekiʻe wela kū'ē, anti-bacterial wehewehe, holoi pale a me ka paʻa i nāʻakika a me nā kumu 'oi aku ka maikaʻi; hiki ke hoʻohana ʻia ma ke ʻano he mea pena i loko o ka methanol, ethanol, propanol, isopropyl alcohol, ethylene glycol, acetone, methyl ethyl ketone a i ʻole diketone alcohol thickener; HPMC formulated emulsified coatings i maikaʻi pulu abrasion; ʻOi aku ka maikaʻi o ka HPMC ma mua o HEC a me EHEC a me CMC no ka mea he ʻoi aku ka maikaʻi o ka HPMC ma mua o HEC a me EHEC a me CMC ma ke ʻano he mānoanoa pena.
2. Highly substituted hydroxypropyl methyl cellulose 'oi aku ka maikaʻi o ke kū'ē i ka maʻi bacteria ma mua o haʻahaʻa substitution, a ua oi aku ka viscosity paʻa i polyvinyl acetate thickeners. Aia nā cellulose ethers ʻē aʻe i ka mālama ʻana ma muli o ka hoʻohaʻahaʻa ʻana i ke kaulahao o ka cellulose ether a hoʻemi i ka viscosity uhi.
3.paint stripper hiki ke wai-soluble HPMC (kahi methoxy he 28% a 32%, hydroxypropoxy he 7% a 12%), dioxymethane, toluene, paraffin, ethanol, methanol hoʻonohonoho, e hoʻopili ʻia i ka ʻili pololei, me ka viscosity pono a me ka volatility. Hoʻopau kēia mea pena pena i ka nui o nā peʻa maʻamau, nā varnish, enamels, a me kekahi mau epoxy esters, epoxy amides, catalyzed epoxy amides, acrylates, a me nā mea ʻē aʻe. ʻOi aku ka maikaʻi o ka mea huki pena no nā ʻili lāʻau.
4.Water emulsion pena hiki ke haku i 100 hapa o inorganic a organic puaʻa, 0.5 ~ 20 hapa o ka wai-soluble alkyl cellulose a hydroxyalkyl cellulose a me 0.01 ~ 5 hapa o ka polyoxyethylene etera a etera ester. No ka laʻana, loaʻa ka kala ma ka hui ʻana i nā ʻāpana 1.5 o HPMC, 0.05 mau ʻāpana o ka polyethylene glycol alkyl phenyl ether, 99.7 mau ʻāpana o ka titanium dioxide a me 0.3 mau ʻāpana kalapona ʻeleʻele. A laila hoʻoulu ʻia ka hui ʻana me nā ʻāpana 100 o 50% solid polyvinyl acetate no ka loaʻa ʻana o ka uhi, a ʻaʻohe ʻokoʻa ma waena o ke kiʻi ʻoniʻoni maloʻo i hana ʻia ma ka hoʻopili ʻana ma ka pepa mānoanoa a me ka hamo māmā ʻana me ka pulupulu.
