Nā waiwai mānoanoa o nā ethers cellulose

Hāʻawi nā ethers cellulose i ka viscosity maikaʻi loa i ka mortar pulu, hoʻonui nui i ka hiki ke hoʻopaʻa o ka mortar pulu i ka substrate a hoʻomaikaʻi i ke kūpaʻa sagging o ka mortar, a hoʻohana nui ʻia i ka mortar plastering, ka mortar bonding brick a me nā ʻōnaehana insulation waho. Hiki i ka hopena mānoanoa o ka cellulose ether ke hoʻonui i ka hiki ke anti-dispersing a me ka homogeneity o nā mea i hui hou ʻia, pale i ka delamination mea, ka hoʻokaʻawale a me ka huna wai, a hiki ke hoʻohana ʻia i ka fiber concrete, ka concrete underwater a me ka concrete self-compacting.

ʻO ka hopena mānoanoa o nā ethers cellulose ma nā mea sima ka hopena o ka viscosity o ka hopena cellulose ether. Ma lalo o nā kūlana like, ʻo ke kiʻekiʻe o ka viscosity o ka cellulose ether, ʻoi aku ka maikaʻi o ka viscosity o ka mea sima i hoʻololi ʻia, akā inā kiʻekiʻe loa ka viscosity, e hoʻopilikia ia i ka wai a me ka hana o ka mea (e laʻa me nā pahi plaster sticky). ʻO nā mortars leveling ponoʻī a me ka sima compacting ponoʻī, e pono ai ka wai kiʻekiʻe, pono ka viscosity haʻahaʻa o nā ethers cellulose. Eia kekahi, ʻo ka hopena mānoanoa o nā ethers cellulose e hoʻonui i ka pono wai o nā mea sima a hoʻonui i ka hua o ka mortar.

ʻO ka viscosity o nā hopena cellulose ether e pili ana i kēia mau mea: ke kaumaha molekala o ka cellulose ether, ka noʻonoʻo ʻana, ka mahana, ka wikiwiki o ka shear a me ke ʻano hoʻāʻo. Ma lalo o nā kūlana like, ʻo ka nui o ke kaumaha molekala o ka cellulose ether, ʻo ka kiʻekiʻe o ka viscosity o ka hopena; ʻo ke kiʻekiʻe o ka noʻonoʻo ʻana, ʻo ka kiʻekiʻe o ka viscosity o ka hopena, i ka hoʻohana ʻana i ka nānā pono e uku ʻia e pale aku i ka nui o ka dosing a hoʻopilikia i nā waiwai hana o ka mortar a me ka sima; e emi ana ka viscosity o ka hopena cellulose ether me ka piʻi ʻana o ka mahana, a ʻo ke kiʻekiʻe o ka noʻonoʻo ʻana, ʻo ka nui o ka mana o ka mahana; ʻO ka hopena cellulose ether he wai pseudoplastic maʻamau, me ke ʻano o ka shear thinning, ʻo ka nui o ka hoʻāʻo ʻana ʻO ka nui o ka wikiwiki o ka shear o ka hoʻāʻo ʻana, ʻo ka liʻiliʻi o ka viscosity, no laila e hoʻemi ʻia ka cohesion o ka mortar ma lalo o ka hana o nā mana o waho, kahi e kōkua ai i ke kūkulu ʻana o ka mortar, i hiki i ka mortar ke loaʻa ka hana maikaʻi a me ka cohesion i ka manawa like; no ka mea ʻo ka hopena cellulose ether he wai ʻaʻole Newtonian, ʻo nā ʻano hoʻāʻo viscosity hoʻāʻo, nā mea hana a i ʻole ke kaiapuni hoʻāʻo, hiki ke ʻokoʻa loa nā hopena hoʻāʻo hoʻonā cellulose ether like.
