Hoʻohana mau ʻia nā cellulose ethers HEC, HPMC, CMC, PAC, MHEC, etc. Nonionic water-soluble cellulose ether he cohesiveness, dispersion stability a me ka paʻa wai, a he mea hoʻohui pono no nā mea kūkulu hale. Hoʻohana ʻia ʻo HPMC, MC a i ʻole EHEC i ka hapa nui o nā hana sima a i ʻole gypsum-based, e like me ka mortar masonry, mortar sima, ka uhi sima, ka gypsum, ka hui ʻana a me ka milky putty, etc. hoʻomaikaʻi nui i ka Adhesion, he mea nui loa ia no ka plaster, tile cement a me ka putty. Hoʻohana ʻia ʻo HEC i ka sima, ʻaʻole wale ma ke ʻano he retarder, akā he mea mālama wai hoʻi, a hoʻohana pū ʻia ʻo HEHPC ma kēia ʻano. Hoʻohana pinepine ʻia ʻo MC a i ʻole HEC me CMC ma ke ʻano he ʻāpana paʻa o ka wallpaper. Hoʻohana maʻamau ʻia nā eter cellulose medium-viscosity a i ʻole kiʻekiʻe-viscosity i nā mea hale i hoʻopili ʻia i ka pepa pepa.
Hydroxypropyl methylcelluloseHPMCHoʻohana maʻamau ʻia i ka hana ʻana o ka pauka putty pā i loko a me waho me ka viscosity o 100,000 cellulose, i loko o ka lepo maloʻo maloʻo, ka lepo diatom a me nā huahana hale ʻē aʻe, cellulose me ka viscosity o 200,000 ka mea maʻamau i hoʻohana ʻia, a i ka hoʻohālikelike ponoʻī a me nā mea ʻē aʻe. ʻO nā mortar kūikawā, cellulose me ka viscosity o 400 ka mea maʻamau. ʻO ka viscosity cellulose, he hopena paʻa wai maikaʻi kēia huahana, ka hopena mānoanoa maikaʻi a me ka maikaʻi paʻa. Hoʻohana nui ʻia ʻo HPMC i ka ʻoihana kūkulu hale a hoʻohana ʻia i ka nui. Hiki ke hoʻohana ʻia ka cellulose ma ke ʻano he retarder, ka mea mālama wai, ka mānoanoa a me ka mea hoʻopili. He mea koʻikoʻi ka cellulose ether i ka mortar hui maloʻo maʻamau, ka mīkini hoʻoheheʻe ʻia o ka paia o waho, ka momi hoʻonaʻauao ponoʻī, ka pauka maloʻo plastering adhesive, ka pahu hoʻopaʻa tile, ka pauka putty, loko a me waho o ka pā putty, ka mīkini wai wai, nā ʻāpana lahilahi, etc. , he mana koʻikoʻi ko lākou i ka paʻa ʻana o ka wai, koi wai, paʻa, hoʻolohi a me ka hana o ka ʻōnaehana stucco.
Hoʻohui nā huahana Hydroxypropyl methylcellulose HPMC i nā waiwai kino a me nā kemika e lilo i huahana kū hoʻokahi me nā hoʻohana lehulehu. Eia na waiwai like ole.
◆Ka paʻa ʻana o ka wai: Hiki iā ia ke mālama i ka makū ma nā wahi porous e like me nā papa sima a me nā pōhaku lepo.
◆Film-forming: Hiki iā ia ke hana i kahi kiʻiʻoniʻoni akaka, paʻakikī a palupalu me ke kūpaʻa ʻaila maikaʻi loa.
◆Organic Solubility: Hiki ke hoʻoheheʻe ʻia ka huahana i loko o kekahi mau mea hoʻoheheʻe organik, e like me ka ethanol/wai, propanol/wai, dichloroethane a me kahi ʻōnaehana solvent i haku ʻia me ʻelua mau mea hoʻoheheʻe organik.
◆Thermal gelation: ʻO ka hopena wai o ka huahana e hana i ka gel i ka wā e wela ai, a e lilo ka gel i hoʻokumu ʻia i mea hoʻonā ma hope o ka hoʻomaha ʻana.
◆Ka hana o ka ʻili: Hāʻawi i ka hana ʻili i loko o ka hopena e hoʻokō i ka emulsification pono a me ka colloid pale, a me ka hoʻopaʻa ʻana o ka pae.
◆ Hoʻokuʻu: Hiki i ka Hydroxypropyl methylcellulose ke pale i nā ʻāpana paʻa mai ka hoʻopaʻa ʻana, no laila ke kāohi nei i ka hoʻokumu ʻana o nā precipitates.
◆Colloid pale: Hiki iā ia ke pale i nā droplets a me nā ʻāpana mai ka coalescing a i ʻole coagulating.
◆Adhesiveness: Hoʻohana ʻia ma ke ʻano he mea hoʻopili no nā puaʻa, nā huahana paka, a me nā huahana pepa, he mau hana maikaʻi loa ia.
◆Water Solubility: Hiki ke hoʻoheheʻe ʻia ka huahana i loko o ka wai i nā ʻano nui like ʻole, a ʻo ka nui o ka hoʻopaʻa ʻana i kaupalena ʻia e ka viscosity.
◆Non-ionic inertness: ʻO ka huahana he non-ionic cellulose ether, ʻaʻole i hui pū me nā paʻakai metala a i ʻole nā iona ʻē aʻe e hana i nā precipitates insoluble.
◆Acid-base paʻa: kūpono no ka hoʻohana i loko o ka laulā o PH3.0-11.0.
◆ ʻAʻole ʻono a ʻala ʻole, ʻaʻole pili i ka metabolism; hoʻohana ʻia e like me ka meaʻai a me nā mea hoʻohui lāʻau, ʻaʻole lākou e hoʻololi ʻia i ka meaʻai, ʻaʻole e hāʻawi i ka wela.
