Nui nā kumu e pili ana i ka hoʻohana ʻana o ka hydroxypropyl methylcellulose HPMC i nā mea kūkulu hale, ʻoi aku ka plaster gypsum-based, penei:
1 paʻa wai
ʻO ka Hydroxypropyl methylcellulose no ke kūkulu ʻana e pale i ka hoʻopili nui ʻana o ka wai e ka substrate, a i ka wā i hoʻonohonoho pono ʻia ai ka gypsum, pono e mālama ʻia ka wai i loko o ka plaster e like me ka hiki.Kapa ʻia kēia hiʻohiʻona i ka mālama ʻana i ka wai a pili pono i ka viscosity o ka solution hydroxypropyl methylcellulose i kūkulu ʻia i loko o ka stucco.ʻOi aku ka kiʻekiʻe o ka viscosity o ka hopena, ʻoi aku ka kiʻekiʻe o kona hiki ke paʻa wai.Ke hoʻonui ʻia ka nui o ka wai, e emi ana ka mana mālama wai.ʻO kēia ke kumu o ka hoʻonui ʻana o ka wai e hoʻoheheʻe i ka hopena o ka hydroxypropyl methylcellulose no ke kūkulu ʻana, e hopena i ka emi ʻana o ka viscosity.
2 anti-sagging
ʻO ka plaster me nā waiwai anti-sag e hiki ai i nā mea noi ke hoʻopili i nā ʻaʻahu ʻoi aku ka mānoanoa me ka ʻole o ka haʻalulu, a ʻo ia hoʻi, ʻaʻole thixotropic ka plaster ponoʻī, inā ʻaʻole e paheʻe i lalo i ka wā o ka noi.
3 Hoʻemi i ka viscosity, hana maʻalahi
Hiki ke loaʻa ka plaster gypsum haʻahaʻa haʻahaʻa a maʻalahi hoʻi i ka hoʻohui ʻana i nā huahana hydroxypropyl methylcellulose hale.I ka hoʻohana ʻana i nā māka haʻahaʻa haʻahaʻa o ka hydroxypropyl methylcellulose o ka hale, ua hoʻemi ʻia ke kiʻekiʻe o ka viscosity Ua maʻalahi ke kūkulu ʻana, akā nawaliwali ka mana paʻa wai o ka hydroxypropyl methylcellulose haʻahaʻa no ke kūkulu ʻana, a pono e hoʻonui ʻia ka nui o ka hoʻohui.
4 ʻO ke kūpono o ka stucco
No ka paʻa o ka mīkini paʻa maloʻo, ʻoi aku ka maikaʻi o ka hana ʻana i kahi kiʻekiʻe kiʻekiʻe o ka mortar pulu, hiki ke hoʻokō ʻia me ka hoʻohui ʻana i nā wai a me nā ea.Akā ʻoi aku ka nui o ka wai a me ka ea
