ʻEhia nā ʻano o Hydroxypropyl methylcellulose (HPMC)?

Hoʻokaʻawale ʻia ʻo Hydroxypropyl methylcellulose (HPMC) i ke ʻano koke a me ke ʻano wela wela.

ʻO ka hikiwaweHydroxypropyl methylcellulose (HPMC)hoʻopuehu koke i ka wai anuanu a nalowale i ka wai. I kēia manawa, ʻaʻohe viscosity o ka wai, no ka mea, hoʻopuehu wale ʻia ka HPMC i ka wai a ʻaʻole hoʻoheheʻe maoli. Ma kahi o 2 mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous transparent.

Hot-melt Hydroxypropyl methylcellulose (HPMC), ke hui lākou i ka wai anuanu, hiki iā lākou ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela. Ke hāʻule ka mahana i kahi mahana (ʻo ka huahana a Shijiazhuang Lvyuan Cellulose Co., Ltd. he 60 degere Celsius), ʻike mālie ka viscosity a hiki i ka hoʻokumu ʻana o kahi colloid viscous transparent.

Hoʻohana maʻamau ka Hydroxypropyl methylcellulose wela-melt (HPMC) i ka pauka putty a me ka mortar. Hoʻohana ʻia ke ʻano o ka hui ʻana o ka pauka: ua hui ʻia ka pauka HPMC me ka nui o nā mea pauka ʻē aʻe, i hui pū ʻia me kahi huila, a laila hoʻoheheʻe ʻia me ka hoʻohui ʻana i ka wai, a laila hiki ke hoʻoheheʻe ʻia ka HPMC me ka ʻole o ka clumping Cohesion, no ka mea, aia wale nō kēlā me kēia kihi liʻiliʻi. he pauda HPMC liʻiliʻi, e hoʻoheheʻe koke ʻia ke hālāwai me ka wai.

Loaʻa i ka Instant Hydroxypropyl methylcellulose (HPMC) kahi ākea o nā noi. Ma waho aʻe o ka pauka putty a me ka mortar, hoʻohana nui ʻia ia i nā huahana kemika i kēlā me kēia lā e like me ke kāpili wai, pena, a me ka mea holoi.
