ʻO ka cellulose ether kahi polymer semi-synthetic non-ionic, ʻo ia ka wai-soluble a me ka solvent-soluble.Loaʻa nā hopena like ʻole i nā ʻoihana like ʻole.No ka laʻana, i nā mea hale kemika, loaʻa iā ia nā hopena composite penei:
①Ka mea hoʻopaʻa wai, ②Ka mea mānoanoa, ③Ka waiwai hoʻohalikelike, ④Ka waiwai hana kiʻiʻoniʻoni, ⑤Binder
I ka ʻoihana polyvinyl chloride, he emulsifier a me ka dispersant;i loko o kaʻoihana lāʻau lapaʻau, he mea hoʻopaʻa a me ka mea hoʻokuʻu lohi a hoʻokuʻuʻia, a me nā mea'ē aʻe.A laila, e nānā au i ka hoʻohana ʻana a me ka hana o ka cellulose ether i nā ʻano mea hale.
i ka pena latex
I ka ʻoihana pena latex, e koho i ka hydroxyethyl cellulose, ʻo ka kikoʻī maʻamau o ka viscosity like ʻo 30000-50000cps, e pili ana i ka kikoʻī o HBR250, a ʻo ka helu kuhikuhi ma kahi o 1.5‰-2‰.ʻO ka hana nui o ka hydroxyethyl i loko o ka pena latex ʻo ia ka mānoanoa, pale i ka gelation o ka puaʻa, kōkua i ka hoʻopuehu ʻana o ka puaʻa, ka paʻa o ka latex, a hoʻonui i ka viscosity o nā ʻāpana, e kōkua i ka hoʻonui ʻana i ka hana o ke kūkulu ʻana: ʻOi aku ka maʻalahi o ka hydroxyethyl cellulose e hoʻohana.Hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, 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 ke ʻano lohi o ka hydroxyethyl cellulose, a hoʻohana ʻia ka hydroxyethyl cellulose me ka manawa dissolution ʻoi aku ma mua o 30 mau minuke.Penei nā ʻanuʻu: ① E hoʻokomo i ka nui o ka wai maʻemaʻe i loko o kahi pahu i hoʻolako ʻia me kahi mea hoʻouluulu kiʻekiʻe ② E hoʻomaka i ka hoʻoulu ʻana me ka wikiwiki haʻahaʻa, a ma ka manawa like e hoʻohui mālie i ka hui hydroxyethyl i loko o ka hopena ③E hoʻomau i ka hoʻoulu ʻana a hiki i hoʻomoʻu ʻia nā mea granular a pau ④E hoʻohui i nā mea hoʻohui a me nā mea hoʻohui kumu, a me nā mea ʻē aʻe.
2. Hoʻolako ʻia me ka waiʻona makuahine no ka hoʻohana ʻana ma hope
Hiki i kēia ʻano ke koho koke i ke ʻano, a he anti-mildew hopena cellulose.ʻO ka maikaʻi o kēia ʻano hana ʻoi aku ka maʻalahi a hiki ke hoʻohui pololei ʻia i ka pena latex.ʻO ke ʻano o ka hoʻomākaukau ʻana e like me nā ʻanuʻu ①-④.
3. Hana ia i porridge no ka hoʻohana ʻana ma hope
No ka mea, ʻo nā mea hoʻoheheʻe organik he mau mea hoʻoheheʻe maikaʻi ʻole (inoluble) no ka hydroxyethyl, hiki ke hoʻohana ʻia kēia mau mea hoʻoheheʻe e hana i ka porridge.ʻO nā mea hoʻoheheʻe kūlohelohe maʻamau i hoʻohana ʻia, ʻo ia nā wai kūlohelohe i loko o nā hana 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.E hoʻomau i ka hoʻouluʻana a hiki i ka hemo loa.
i ka putty
I kēia manawa, ma ka hapa nui o nā kūlanakauhale o koʻu ʻāina, ua waiwai nui ʻia e ka poʻe ka putty kūpaʻa i ka wai a me ka scrub-resistant environment-friendly putty.Hana ʻia ia e ka hopena acetal o ka waiʻona vinyl a me ka formaldehyde.No laila, hoʻopau mālie ʻia kēia mea e nā kānaka, a hoʻohana ʻia nā huahana cellulose ether series e pani i kēia mea.ʻO ia hoʻi, no ka hoʻomohala ʻana i nā mea hale e pili ana i ke kaiapuni, ʻo cellulose wale nō ka mea i kēia manawa.
I loko o ka putty wai-kūpaʻa, ua māhele ʻia i ʻelua ʻano: putty pauka maloʻo a me putty paste.Ma waena o kēia mau ʻano putty ʻelua, pono e koho ʻia ka methyl cellulose a me ka hydroxypropyl methyl.ʻO ka kikoʻī viscosity ma waena o 40000-75000cps.ʻO nā hana nui o ka cellulose ka mālama ʻana i ka wai, ka hoʻopaʻa ʻana a me ka lubrication.
No ka mea he ʻokoʻa nā ʻano putty o nā mea hana like ʻole, he calcium hina, calcium māmā, sima keʻokeʻo, a me nā mea ʻē aʻe, a ʻo kekahi he pauka gypsum, calcium hina, calcium māmā, etc., no laila nā kikoʻī, viscosity a me ke komo ʻana o cellulose i loko ʻokoʻa nō hoʻi nā papa ʻelua.ʻO ka nui i hoʻohui ʻia ma kahi o 2‰-3‰.
