ʻO ka cellulose ether kahi polymer semi-synthetic non-ionic, hiki ke hoʻoheheʻe ʻia i ka wai a me ka solvent ʻelua, i nā ʻoihana like ʻole i hana ʻia e ka hana ʻokoʻa, e like me nā mea hana hale kemika, loaʻa iā ia ka hopena hui:
① mea mālama wai, ② mea mānoanoa, ③ pae, ④ hana kiʻiʻoniʻoni, ⑤ mea hoʻopaʻa.
I ka ʻoihana PVC
he mea emulsifier, dispersant;
I ka ʻoihana excipient lāʻau lapaʻau
he ʻano mea hoʻopaʻa a hoʻokuʻu lohi i ka iwi iwi, no ka mea, he ʻano like ʻole ka cellulose ether, no laila ʻo ia ka māla i hoʻohana nui ʻia.Ma lalo wau e nānā i ka hoʻohana ʻana i ka cellulose ether i nā ʻano mea kūkulu hale a me ke kuleana.
I ka pena latex
Ma ka laina pena latex, e koho i ka hydroxyethyl cellulose, ʻo ka kikoʻī maʻamau o ka viscosity like he 3000-50000cps, pili ia i nā kikoʻī HBR250, ʻo ka helu kuhikuhi maʻamau 1.5‰-2‰.ʻO ka hana nui o ka hydroxyethyl cellulose i ka pena latex ʻo ia ka mānoanoa, pale i ka gelation pigment, hāʻawi i ka hoʻopuehu ʻana o ka puaʻa, latex, kūpaʻa, a hiki ke hoʻomaikaʻi i ka viscosity o nā ʻāpana, hāʻawi i ka hana pae o ka hana: He maʻalahi ka hoʻohana ʻana o Hydroxyethyl cellulose. , hiki ke hoʻoheheʻe ʻia ka wai anuanu a me ka wai wela, a ʻaʻole pili i ka waiwai PH.Hiki ke hoʻohana pono ʻia ma waena o ka waiwai PI 2 a me 12. ʻO nā ʻano o ka hoʻohana ʻana penei:
I. Hoʻohui pololei i ka hana
No kēia ʻano, pono e koho ʻia ka hydroxyethyl cellulose me ka manawa hoʻoheheʻe ʻoi aku ma mua o 30 mau minuke.Penei ke kaʻina hana: (1) e kiʻekiʻe e ʻoki i ka pahu blender quantitative wai maʻemaʻe (2) ka ikaika o loko o ka poʻe i hoʻomaka e haʻahaʻa i ka hui ʻana, hydroxyethyl ʻaʻahu mālie i ka manawa like e hui i ka hopena o (3) E hoʻomau i ka hoʻoulu ʻana a hiki i ka hoʻohui ʻana i nā mea hoʻohui ʻē aʻe a me nā mea hoʻohui alkaline (5) a hiki i ka hoʻoheheʻe ʻana o nā hydroxyethyl a pau, e hoʻohui i nā mea ʻē aʻe o ka formula, e wili ana i ka huahana i pau.
2, lako me ka waiona makuahine
Hiki i kēia ʻano ke koho i ka cellulose hiki ke hoʻopaʻa ʻia, a loaʻa ka hopena i ka mildew.ʻO ka maikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi, hiki ke hoʻohui pololei i ka pena emulsioni, e hana i kahi ʻano like me ka ①–④ ʻano like.
3, me ka porridge no ka hoʻohana
No ka mea, ʻo nā mea hoʻoheheʻe organik he mau mea hoʻoheheʻe maikaʻi ʻole (inoluble) no ka hydroxyethyl, hiki ke hoʻohana ʻia e hoʻomākaukau i ka porridge.ʻO nā mea hoʻoheheʻe kūlohelohe i hoʻohana pinepine ʻia, ʻo ia nā wai kūlohelohe i loko o nā ʻano pena latex, e like me ka ethylene glycol, propylene glycol a me nā mea hana kiʻiʻoniʻoni (e like me diethylene glycol butyl acetate), hiki ke hoʻohui pololei ʻia ka porridge hydroxyethyl cellulose i ka pena, ma hope o ka hoʻohui ʻana, e hoʻomau i ka hoʻoulu ʻana a hiki i ka hemo loa ʻana.
I loko o ka pulupulu pā ʻili
I kēia manawa, aia ʻo Kina i ka hapa nui o ke kūlanakauhale wai kūʻē, kūʻē i ka swab o ka putty pale kaiapuni ua lawe nui ʻia e ka poʻe, i kekahi mau makahiki i hala aku nei, no ka mea, ʻo ka putty i hana ʻia i ke kāpili hale e hoʻomālamalama i ka formaldehyde kinoea pōʻino i ke olakino o nā kānaka. Hana ʻia ke kāpili me ka waiʻona polyvinyl a me ka hopena acetal formaldehyde.No laila ua hoʻopau mālie ʻia kēia mea e ka poʻe, a ʻo ka hoʻololi ʻana o kēia mea he cellulose ether moʻo o nā huahana, ʻo ia hoʻi, ka hoʻomohala ʻana i nā mea kūkulu hale mālama kaiapuni, ʻo ka cellulose wale nō ke ʻano mea i kēia manawa.
Hoʻokaʻawale ʻia ka putty pale wai i ka putty pauka maloʻo a me ka putty paste ʻelua ʻano, ʻo kēia mau ʻano putty ʻelua e koho maʻamau i ka methyl cellulose a me ka hydroxypropyl methyl ʻelua ʻano, ʻo ka viscosity kikoʻī maʻamau i 40,000-75000cps ma waena o ka mea kūpono loa, i ka hana nui o cellulose ʻO ka putty ka paʻa wai, ka hoʻopaʻa ʻana, ka lubrication a me nā hopena ʻē aʻe.
No ka mea ʻaʻole like ke ʻano putty o kēlā me kēia mea hana, ʻo kekahi he calcium hina, calcium māmā, sima keʻokeʻo, ʻo ka pauka gypsum, calcium hina, calcium māmā, a me nā mea ʻē aʻe, no laila ka kikoʻī kikoʻī a me ka infiltration nui o cellulose o nā ʻano ʻelua. ʻaʻole like, ʻo ka nui o ka hoʻohui ʻana he 2‰-3‰ a i ʻole.
