Hydroxypropyl MethylCellulose (HPMC)

ʻO ka Hydroxypropyl methyl cellulose (HPMC) he mānoanoa maikaʻi loa a hiki ke hoʻohana ʻia ma ke ʻano he anti-dispersant concrete maikaʻi loa.Ua hoʻohana nui ʻia ʻo HPMC i ka ʻoihana kūkulu.Anti-dispersant ho'āʻo Anti-dispersant mea he koʻikoʻi oaoieei index e ana i ka maikai o ka anti-dispersant.

ʻO ka HPMC he pūhui polymer wai, ʻike ʻia hoʻi he resin soluble wai a i ʻole polymer wai, e hoʻonui i ka kūlike o ka wai hui ʻana ma o ka hoʻonui ʻana i ka viscosity o ka hui ʻana, he mea hydrophilic polymer, hiki ke hoʻoheheʻe i ka wai a hana i kahi hopena. a i ʻole ka hoʻopuehu ʻana.Hiki ke ʻike ʻia i ka wā e piʻi ai ka nui o ka naphthalene series efficient water reducing agent, ʻo ka hoʻohui ʻana o ka mea hoʻemi wai e hōʻemi i ka anti-dispersion o ka mortar sima hou.

ʻO kēia no ka mea ʻo ka naphthalene ʻōnaehana hoʻohaʻahaʻa wai kūpono i ka surfactant, i ka wā i hoʻohui ʻia ai ka mea hoʻohaʻahaʻa wai i ka mortar, ka mea hoʻohaʻahaʻa wai i ka ʻili o ka ʻili sima me ka uku hoʻokahi, hana ka repulsion uila i nā ʻāpana sima e hana i ka flocculation structure. ua hoʻokaʻawale ʻia, ʻo ka wai i hoʻokuʻu ʻia i loko o ka hale, e hana i kahi hapa o ka nalowale o ka wai sima.I ka manawa like, me ka hoʻonui ʻana o ka hui ʻana o ka HPMC, ʻoi aku ka maikaʻi a me ka maikaʻi o ka hoʻopuehu ʻana o ka mīkini sima hou.
