He mea hoʻohui waiwai ʻo EipponCell HPMC YB 520M no nā noi plaster-based, e hāʻawi ana i kēia mau waiwai:
Ka hāʻawi maikaʻi: Ke hoʻoheheʻe ʻia ka HPMC i ka wai, hōʻike ia i ka hana ma luna, e hōʻoiaʻiʻo ana i ka hāʻawi like ʻana o nā mea sima i loko o ka ʻōnaehana pahū.Ma ke ʻano he colloid pale, hoʻopili ka HPMC i nā ʻāpana paʻa, e hana ana i kahi papa ma ko lākou ʻili i waho.
Hoʻopaʻa wai: Ma muli o kona ʻano molekala kū hoʻokahi, kōkua ka HPMC solution i ka mālama ʻana i ka wai i loko o ka pahū, e hoʻokuʻu mālie iā ia no kahi manawa lōʻihi. ʻO ka substrate.. Noho ka wai i hoʻopaʻa ʻia ma luna o ka ʻili o ka mea hou, e hāpai ana i ka hydration sima a hoʻonui i ka ikaika hope o ka plaster.
Paʻa a paʻa: Ua hōʻike ka HPMC i ka paʻa i nā kaiapuni ʻelua a me ka alkali.. Paʻa loa kona ʻano wai i ka pae pH mai 2 a hiki i 12. ʻOiai he liʻiliʻi ka hopena o ka soda caustic a me ka wai lime i kona mau waiwai, hiki i ka alkalis ke hoʻoneʻe i kona hemo a hoonui iki i kona viscosity.
Hoʻonui i ka hana hana: ʻO ka hoʻohui ʻana o HPMC e hoʻonui nui i ka hana hana o nā morta. aiʻole nā pōhaku lepo a me ka papa kumu.Eia kekahi, ʻo ka hele ʻana o ka HPMC e hoʻolōʻihi i ka manawa hana, e kūpono loa ia no nā hana kūkulu nui.
