ʻO ka hoʻohana ʻana i nā viscosities like ʻole o ka cellulose i nā huahana

ʻO ka hydroxypropyl methylcellulose papa hana ʻenehana i hoʻohana ʻia no ka mortar (e pili ana i ka cellulose maʻemaʻe, ʻaʻole i hoʻololi i nā huahana i hoʻololi ʻia) i ʻike ʻia e ka viscosity, a ua hoʻohana maʻamau ʻia nā māka aʻe (ʻo ka viscosity ka hui):

Haʻahaʻa viscosity: 400

Hoʻohana nui ʻia no ka mortar self-leveling; haʻahaʻa ka viscosity, ʻoiai ʻaʻole maikaʻi ka paʻa ʻana o ka wai, akā maikaʻi ka waiwai o ka pae ʻana, a ʻoi aku ka kiʻekiʻe o ka mortar.

Medium a haʻahaʻa viscosity: 20000-40000

Hoʻohana nui ʻia no nā tile adhesives, caulking agents, anti-cracking mortars, thermal insulation bonding mortars, etc.; maikaʻi ke kūkulu ʻana, liʻiliʻi ka wai, kiʻekiʻe kiʻekiʻe.

ʻO ka viscosity waena: 75000-100000

Hoʻohana nui ʻia no ka putty; maikaʻi ka mālama ʻana i ka wai.

Kiʻekiʻe viscosity: 150000-200000

Hoʻohana nui ʻia ia no ka polystyrene particle thermal insulation mortar rubber powder and vitrified microbead thermal insulation mortar; kiʻekiʻe ka viscosity, ʻaʻole maʻalahi ka hāʻule ʻana o ka mortar, a hoʻomaikaʻi ʻia ke kūkulu ʻana.

Ma nā hoʻohana pono, pono e hoʻomaopopo ʻia i nā wahi me nā ʻokoʻa wela nui ma waena o ke kauwela a me ka hoʻoilo, ua ʻōlelo ʻia e hoʻohana i kahi viscosity haʻahaʻa haʻahaʻa i ka hoʻoilo, ʻoi aku ka maikaʻi o ke kūkulu ʻana. A i ʻole, ke haʻahaʻa ka mahana, e piʻi ka viscosity o ka cellulose, a kaumaha ka lima i ka wā e ʻoki ai.

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Ma ka noʻonoʻo ʻana i ke kumukūʻai, nui nā hale hana mortar pauka maloʻo e hoʻololi i ka cellulose viscosity haʻahaʻa (20000-40000) me ka cellulose medium-viscosity (75000-100000) e hōʻemi i ka nui o ka hoʻohui. Pono e koho ʻia nā huahana mortar mai nā mea hana maʻamau a ʻike ʻia.

ʻO ka pilina ma waena o ka viscosity a me ka mahana o HPMC:

ʻO ka viscosity o ka HPMC he like ia me ka mahana, ʻo ia hoʻi, piʻi ka viscosity i ka emi ʻana o ka mahana. ʻO ka viscosity o kahi huahana a mākou e ʻōlelo pinepine ai e pili ana i ka hopena hoʻāʻo o kāna 2% aqueous solution ma kahi mahana o 20 degere Celsius.
