Hoʻolālā ʻia ka hydroxypropyl methylcellulose ether no nā huahana wai.Hoʻopili ʻia ka ʻili o ka hydroxypropyl methylcellulose ether me ka glyoxal ma lalo o kahi mahana a me ka waiwai pH.ʻO ka hydroxypropyl methyl cellulose ether i mālama ʻia ma kēia ʻano e hoʻopuehu wale ʻia i loko o ka wai anuanu kū ʻole me ka ʻole o ka pehu a me ka viscosity, kahi mea e hoʻopaneʻe ai i ka pehu.I kēia manawa, hoʻoulu ʻia ka wai wai no 5-10 mau minuke a i ʻole ke hoʻololi ʻia ke kaiapuni hoʻonā (waiwai PH) i alkaline, hoʻomaka ka hydroxypropyl methylcellulose ether e pehu a hoʻohua i ka viscosity.ʻO kēia ʻano i mālama ʻia i ka ʻili ke kapa ʻia he ʻano koke.
ʻO ka hiʻohiʻona o ka hydroxypropyl methylcellulose koke ka wā e hālāwai ai me ka wai anuanu, e hoʻopuehu koke ia i ka wai anuanu, akā pono ka manawa e piʻi ai kona viscosity, no ka mea, ʻaʻole ia e hoʻoheheʻe i loko o ka wai. manaʻo nui.Hiki i kona viscosity i ka waiwai kiʻekiʻe ma kahi o 20 mau minuke a ʻoi aku paha.ʻO ka pōmaikaʻi o kēia, ʻo ia ka mea i hoʻohana ʻia i loko o kahi ʻoihana kikoʻī me ka ʻole o ka hui ʻana o ka pauka maloʻo, a i ʻole i ka wā e pono ai e hoʻoheheʻe ʻia a ʻaʻole hiki ke hoʻohana ʻia ka wai wela ma muli o nā kūlana lako a me nā kumu ʻē aʻe.Hoʻopau koke ka hydroxypropyl methylcellulose i kēlā pilikia.
Hoʻopuehu koke ka hydroxypropyl methylcellulose i ka wai (ʻo ka dispersion degree he 100%), hoʻoheheʻe koke ʻia, ʻaʻole clumping, ʻoi aku hoʻi i ka pae hope, ʻo ka colloidal solution he kiʻekiʻe kiʻekiʻe (a hiki i 95%) a me ke kūlike nui, e hoʻonā i nā pilikia. ma nā hoʻohana pono.ʻO nā kaohi, ka hoʻonui ʻana i ke kahua o ka noi, e like me ka noi ʻana i ke kāpili kūkulu ʻana, ka noi ʻana i nā hui hoʻohui wai, a me nā kahua kūikawā e like me ka holoi ʻana i kēlā me kēia lā.
Ua hoʻolauna mākou i nā lako hana kiʻekiʻe o ka honua a me ka ʻenehana, loaʻa kahi laina hana hou o ka cellulose ether a me ka pauka latex redispersible, a e hōʻoia i ka hāʻawi ʻana i nā mea hoʻohana i nā huahana ʻoluʻolu me kāna ʻōnaehana hoʻomalu maikaʻi, ʻōnaehana hoʻāʻo a me ka lawelawe ma ka pūnaewele.ʻO nā huahana alakaʻi he hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, redispersible latex pauka pauka.Hoʻohana nui ʻia nā huahana i ke kūkulu ʻana, ka ʻoihana kemika, ka pena, ka ʻoihana kemika i kēlā me kēia lā, ka ʻoihana koa a me nā māla ʻē aʻe, a ua hana ʻia i mau mea hana kiʻiʻoniʻoni, adhesives, dispersants, stabilizers, thickeners, etc.
Ke hilinaʻi nei i ka maikaʻi o kāna huahana ponoʻī a me kona kūlana a me ka mana i ka ʻoihana hoʻohui i ka lepo maloʻo hale mea hoʻohui, a ma lalo o ka manaʻo o ka mālama mau ʻana i ka misionari ʻoihana o ka maikaʻi ma mua, ke hui pū nei me nā mea hana kaulana o ka honua a me ka home no nā huahana hoʻohui.Nā hana kākoʻo: polypropylene fiber, Wood fiber, starch ether i hoʻololi ʻia, polyvinyl alcohol powder, powder defoamer, water reducer, water repellent, calcium formate a me nā mea hoʻohui maloʻo maloʻo.
