He aha nā mea e pili ana i ka paʻa ʻana o ka wai o ka hydroxypropyl methyl cellulose?

Hoʻohana ʻia ka pauda HpmcHiki ke hoʻopuehu ʻia a hoʻopuehu maikaʻi ʻia i loko o ka momi sima a me nā huahana gypsum, e kāwili ana i nā ʻāpana paʻa a pau a hana i kahi kiʻi ʻoniʻoni.Hoʻokuʻu mālie ʻia ka makū i loko o ke kumu no kahi manawa lōʻihi, a ke hoʻoheheʻe ʻia me nā mea cementitious inorganic, a laila e hōʻoia i ka ikaika paʻa a me ka ikaika compressive o nā mea.

No laila, i ke kiʻekiʻe wela kauwela kūkulu, i mea e hoʻokō i ka wai paʻa hopena, ia mea pono e hoʻohui i lawa ka nui ohydroxypropyl methyl cellulosee like me ke ʻano, inā ʻaʻole e hiki mai nā pilikia maikaʻi e like me ka lawa ʻole o ka hydration, ka emi ʻana o ka ikaika, ka haki ʻana, ka hollowing, a me ka wehe ʻana ma muli o ka hoʻomaloʻo wikiwiki ʻana e hiki mai, a e hoʻonui pū i ka paʻakikī o nā limahana i ke kūkulu ʻana.I ka emi ʻana o ka mahana, hiki ke hoʻemi iki ʻia ka nui o ka hydroxypropylmethylcellulose, a hiki ke hoʻokō ʻia ka hopena paʻa wai like.

Hoʻopili ʻia ka paʻa wai o ka hydroxypropyl methyl cellulose e ka mahana a me nā kumu penei:

1. Homogeneity o hydroxypropyl methyl cellulose

Homogenehydroxypropyl methyl cellulose, Methoxy pūʻulu a me ka hydroxypropyl puʻunaue like, a me ka nui o ka paʻa wai.

2. Ka wela o ka HPMC thermal gel

He kiʻekiʻe ka wela o ka gel thermal a me ka nui o ka mālama ʻana i ka wai;ʻO ka mea ʻē aʻe, haʻahaʻa ka nui o ka mālama ʻana i ka wai.

3. Hydroxypropylmethylcelluloseviscosity

I ka wa o ka viscosity oHPMCpiʻi, piʻi pū ka paʻa wai;Ke piʻi ka viscosity i kahi pae, ʻoi aku ka lohi o ka hoʻonui ʻana i ka paʻa wai.

4. Hoʻohui ka nui o ka hydroxypropyl methyl cellulose

ʻOi aku ka nui o ka hydroxypropyl methyl cellulose i hoʻohui ʻia, ʻoi aku ka kiʻekiʻe o ka pae paʻa wai a ʻoi aku ka maikaʻi o ka hopena paʻa wai.Ma ka laulā o 0.25-0.6% hoʻohui, piʻi wikiwiki ka nui o ka mālama ʻana i ka wai me ka piʻi ʻana o ka nui o ka hoʻohui;Ke piʻi aʻe nei ka nui o ka hoʻohui ʻana, e lohi ka piʻi ʻana o ka paʻa wai
