Mea Hana Maʻemaʻe kiʻekiʻe Kina mea hana lima hoʻomaʻemaʻe lima pauka mānoanoa Hydroxypropyl Methyl Cellulose HPMC
HPMChe non-ionic, wai hoʻoheheʻe cellulose ether e hana i nā kiʻiʻoniʻoni, paʻa wai, kūpaʻa, adhesiveness, ʻoi aku ka nui o ka hoʻohana ʻana no nā mea hana no ka mea ua koho ʻia e hoʻomaikaʻi i ka adhesion, ka paʻa ʻana o ka wai, a me ka lubricity, ke emi a me ke kū'ē ʻana.Hoʻomaikaʻi ka cellulose ethers i hoʻololi ʻia i ka paheʻe ʻana, ke kūʻē ʻana i ke kaomi a me ka wahine tensile.No laila, no nā motika sima a me ka plaster, ʻo ia kāu koho maikaʻi loa.He pauda keʻokeʻo a keʻokeʻo paha, ʻaʻohe mea ʻawaʻawa, a hiki ke hoʻoheheʻe ʻia i ka wai wela a i ʻole ke anuanu.
HPMChoʻohana ʻia no nā seramika, paka a me nā mea holoi, etc.
No nā ʻano like ʻole o ka binder,Youngcelhiki ke hāʻawi i nā huahana cellulose ether e hoʻokō maʻalahi i nā koi like ʻole.
- Hiki i ka hana kiʻekiʻe
- Koi wai kiʻekiʻe a me ka puka kiʻekiʻe
- Kūʻē sag maikaʻi
- Ka manawa wehe lōʻihi
- He maʻalahi ka laha ʻana a ʻaʻole pili i ka pahi
