He aha ka viscosity o ka hydroxypropyl methylcellulose hpmc?

He 100,000 ka viscosity o ka pauka Putty no ka paia o loko. He kiʻekiʻe aʻe nā koi o ka mortar sima no ka hoʻoponopono ʻana, a maʻalahi ka viscosity o 150,000. Eia kekahi, ʻo ka hana koʻikoʻi o ka HPMC ʻo ka laka ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka pauka putty, inā maikaʻi ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity (7-80,000), hiki iā ia ke loaʻa i kahi viscosity kūlohelohe kiʻekiʻe a ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Ke ʻoi aku ka viscosity ma mua o 100,000, liʻiliʻi ka hopena o ka viscosity i ka paʻa ʻana o ka wai.

He aha ka hopena nui oHPMC i ka pauda putty, a inā paha e hana ʻia ke kemika organik?

Hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana i ka pauka putty.

Mānoanoa: Hiki ke hoʻopaʻa ʻia ka Methylcellulose me ka lana ʻana, nā ʻoluʻolu wai e mālama i ka hana like a paʻa a pale i nā kau kahe.

Paʻa wai: maloʻo mālie ka pauka o ka paia o loko, a ʻike ʻia ka lime calcium i hoʻohui ʻia i ka hoʻohana ʻana i ka wai.

Hana ʻenekinia: He hopena lubricating ka methyl cellulose, hiki ke hana i ka pauka putty i kahi hoʻolālā ʻenehana maikaʻi loa.

ʻAʻole pili ka HPMC i nā hoʻololi kemika akā i ka hoʻohui wale nō. ʻO ka pauda putty, ma ka paia, he hoʻololi kemika, no ka mea, aia ka hoʻololi hou ʻana o ka mea kemika, puka ka pauda putty mai loko mai o ka paia, wili i ka pauda, ​​a hoʻohana hou ʻia no ka mea ua hana ʻia kahi mea kemika hou (calcium carbonate).

ʻO nā mea nui o ka lehu lele calcium: Ca(oh)2, Cao a me kahi mea liʻiliʻi o Caco3 pūhui, Caoh2oCa(oh)2-Ca(oh)2caco3h2o lime hiki ke hoʻololi i ka calcium bicarbonate i loko o ka wai a me ke kinoea, ʻoiai ʻo mpc ʻOi aku ka ikaika o ka lehu lele Calcium, ʻaʻole ia e komo i kekahi noʻonoʻo.

He aha ka mea e pono e hoʻolohe i ka noi maoli o ka pilina ma waena o ka viscosity a me ka mahana o HPMC?

Hoʻohālikelike ka viscosity o HPMC me ka mahana, ʻo ia hoʻi, piʻi ka viscosity me ka emi ʻana o ka mahana. ʻO ka viscosity o ka huahana, ka viscosity o ka huahana ʻo ia ka 2% solution ma kahi mahana o 20 degere Celsius, a me nā hopena hōʻike.

Ma nā noi kikoʻī, pono e uku ʻia ka nānā ʻana i nā wahi me nā ʻokoʻa wela nui ma waena o ke kauwela a me ka hoʻoilo, a ua manaʻo nui ʻia e hoʻohana i kahi viscosity haʻahaʻa i ka hoʻoilo. Inā ʻaʻole, haʻahaʻa ka viscosity, piʻi ka viscosity o ka cellulose, a kaumaha nā ʻōpala.

Medium viscosity: 75000-100000 kūpono no ka pauka putty
Ke kumu: mālama maikaʻi i ka wai

ʻO ka viscosity kiʻekiʻe: 150000-200000 kūpono no ka polystyrene particle insulation mortar a me ka inorganic insulation mortar.
ʻO nā kumu: kiʻekiʻe viscosity, paʻakikī ka wehe ʻana i ka mortar sima, nalowale o ka gloss, hoʻomaikaʻi i ke kūkulu ʻana.
