Focus on Cellulose ethers

Ka hoʻohana ʻana i ka cellulose ether i nā mea kūkulu kaiapuni

ʻO ka cellulose ether kahi ʻano o ka polymer semi-synthetic non-ionic, me ka solubility wai a me ka solvability o nā ʻano ʻelua, i nā ʻoihana like ʻole i hana ʻia e ka hana, ʻokoʻa, e like me nā mea hale kemika, loaʻa iā ia ka hopena composite penei: ① paʻa wai. mea hana ② mānoanoa ③ pae ④ hana kiʻiʻoniʻoni ⑤ binder; I ka ʻoihana polyvinyl chloride, he emulsifier, dispersant; I loko o ka ʻoihana lāʻau lapaʻau, he ʻano mea hoʻopaʻa a me ka hoʻokuʻu lohi a me ka hoʻokuʻu ʻana i nā mea iwi, no ka mea, he ʻano like ʻole ka cellulose i nā hopena composite, no laila ʻo ia ka māla i hoʻohana nui ʻia. Ma ʻaneʻi ke nānā aku nei au i ka hoʻohana ʻana i ka cellulose ether i nā mea kūkulu hale mālama kaiapuni a me ke kuleana.
1, pena latex

I ka laina pena LATEX, makemake ʻoe e KOHO hydroxyethyl cellulose, ʻo ka kikoʻī maʻamau o ka viscosity ʻo RT30000- 50000CPS, ʻo ka helu kuhikuhi maʻamau ʻo 1.5‰-2‰ mau ʻaoʻao hema a ʻākau. ʻO ka hana nui o ka hydroxyethyl i ka pena latex ʻo ia ka mānoanoa, pale i ka gelation pigment, kōkua i ka hoʻopuehu puaʻa, latex, kūpaʻa, a hiki ke hoʻomaikaʻi i ka viscosity o nā ʻāpana, kōkua i ka hoʻonui ʻana i ka hana: ʻoi aku ka maʻalahi o ka hydroxyethyl cellulose e hoʻohana, anu. a hiki ke hoʻoheheʻe ʻia ka wai wela, ʻaʻole pili i ka waiwai PH, ma waena o PH 2 a me 12 hiki ke hoʻohana ʻia, ka hoʻohana ʻana i nā ʻano ʻekolu:

I. Hoʻohui pololei:
Pono e koho kēia ʻano hydroxyethyl cellulose i ke ʻano hoʻopaneʻe - ka manawa i hoʻoheheʻe ʻia ma mua o 30 mau minuke o ka hydroxyethyl cellulose, ʻo kāna mau ʻanuʻu e like me kēia: (1) pono e ʻoki i ka pahu blender kiʻekiʻe a me ka wai maʻemaʻe quantitative (2) hoʻomaka nā kānaka e lohi i ka hoʻoulu ʻana mau. , i ka manawa like e hoʻohui mālie i ka hydroxyethyl i ka hopena o (3) e hoʻomau i ka hoʻoulu ʻana a hiki i nā mea granular pulu (4) e hui pū i nā mea hoʻohui ʻē aʻe a me nā mea hoʻohui alkaline (5) hoʻoulu a hoʻoheheʻe ʻia nā hydroxyethyl a pau, e hoʻohui i nā mea ʻē aʻe o ka formula. , e wili ana i ka huahana i pau.

ⅱ, lako me ka waiʻona makuahine e kali ana:
Hiki i kēia ʻano ke koho i ke ʻano koke, a loaʻa i ka mildew - ka hopena hōʻoia o ka cellulose. ʻOi aku ka maikaʻi o kēia ʻano hana, hiki ke hoʻohui pololei ʻia i ka pena latex, ʻo ke ʻano hoʻomākaukau e like me ①- ④ mau ʻanuʻu.

ⅲ. E lawelawe me ka porridge:
No ka mea, ʻaʻole makemake ʻia nā mea hoʻoheheʻe organik (inoluble) i ka hydroxyethyl, hiki ke hoʻohana ʻia e hana i ka porridge. ʻO ka mea maʻamau i hoʻohana ʻia ʻo ORGANIC SOLVENT, ʻo ia ka ORGANIC LIQUID IN LATEX PAINT FORMULA, E like me GLYCOL, PROPYLENE GLYCOL A ME FILM-forming AGENT (LIKE DIETHYLENE glycol butyl acetic acid GREASE), CELLULOSE OF HYDROXYETHYL PARTYL OF COGERINLY IN. E HOOMAU ANA I KA AUAU E HELE LOA I keia manawa.

2, ʻokiʻoki i ka putty pā

I kēia manawa, ʻo ke ʻano putty pale kaiapuni, ʻo ia ka wai-kū a pale i ka holoi ʻana i ka hapa nui o nā kūlanakauhale, ua nānā pono ʻia e ka poʻe. I nā makahiki i hala iho nei, no ka mea, ʻo ka putty i hana ʻia me ke kāpili hale e hoʻomālamalama i ke kinoea formaldehyde e hōʻino i ke olakino o nā kānaka, ua hana ʻia ke kāpili hale me ka polyvinyl alcohol a me formaldehyde no ka hopena acetal. No laila, hoʻopau mālie ʻia kēia mea e nā kānaka, a ʻo ka hoʻololi ʻana o kēia mea he cellulose ether series huahana, ʻo ia hoʻi, ka hoʻomohala ʻana i nā mea kūkulu hale mālama kaiapuni, ʻo ka cellulose wale nō ke ʻano o nā mea.

I loko o ka wai kūpaʻa putty ua māhele ʻia i ʻelua ʻano o ka pauka maloʻo putty a me ka putty paste, ʻo kēia mau ʻano putty ʻelua makemake e koho i ka methyl cellulose i hoʻololi ʻia a me ka hydroxypropyl methyl ʻelua mau ʻano, nā kikoʻī viscosity ma waena o 3000-60000CPS ka mea kūpono loa, ka mea nui. ʻO ke kuleana o ka cellulose i ka putty ka paʻa ʻana o ka wai, ka hoʻopaʻa ʻana, ka lubrication, etc.

No ka mea ʻaʻole like ke ʻano putty o kēlā me kēia mea hana, he calcium hina, calcium māmā, sima keʻokeʻo, ʻo ka pauka gypsum, calcium hina, calcium māmā, no laila ʻaʻole like ka kikoʻī kikoʻī a me ka infiltration o cellulose o nā ʻano ʻelua. , ʻo ka nui o ka hoʻohui ʻana ma kahi o 2‰-3‰.

I loko o ka pā pā e hoʻoluhi ʻia me ka hana ʻana o ke keiki, ua loaʻa i ke kumu o ka pā kekahi absorbent (ʻo ka pā pōhaku o ka helu bibulous he 13%, ʻo ka ʻōpala he 3-5%), i hui pū ʻia me ka evaporation o ka honua i waho, no laila inā e luhi me ke keiki ʻOi aku ka wikiwiki o ka lilo ʻana o ka wai, e alakaʻi i ka māwae a i ʻole ka hanana e like me ka pollen, i nāwaliwali ka ikaika o ka putty, no laila, ma hope o ka hui ʻana i ka cellulose ether e hoʻonā i kēia pilikia. Akā ʻo ka maikaʻi o ka mea hoʻopihapiha, ʻoi aku ka nui o ka lehu calcium, he mea nui loa. Ma muli o ka viscosity kiʻekiʻe o ka cellulose, hoʻonui ia i ka ikaika lana o ka putty, a pale i ke ʻano o ke kahe e kau ana ma ke kūkulu ʻana, a ʻoi aku ka ʻoluʻolu a me ka mālama ʻana i ka hana ma hope o ka ʻoki ʻana.

3, ka paʻi pōhaku
I loko o ka mīkini palaki, loaʻa loa i ka ikaika loa, pono e hana i ka sima hydration hopena loa, o ka oi aku i loko o ke kauwela, i ke kukulu ana i ka mīkini palaki wai poho wikiwiki loa, piha hydrated ana ma ka ho'ōla wai, keia ala mea he pau o ka wai punawai. ʻO ka hana kūponoʻole, aia ke kī ma luna o kaʻili,ʻaʻole i piha ka wai a me ka hydration, no laila,ʻo nā ala e hoʻoponopono ai i kēia pilikia, Ma ka mortar concrete e koho maʻamau e hoʻohui i ka hydroxypropyl methyl cellulose a iʻole ka methyl cellulose, nā kiko'ī viscosity ma waena o 20000- 60000CPS, e hoʻohui. ma kahi o 2‰–3‰, hiki ke hoʻonui ʻia ka nui o ka paʻa ʻana o ka wai i ʻoi aku ma mua o 85%, hiki ke hoʻohana ʻia ka hoʻohana ʻana i ka mīkini palaki no ka pauka maloʻo i hui pū ʻia ma hope o ka hoʻohui ʻana i ka wai.

4, gypsum pena, gypsum pipili, gypsum caulking

Me ka hoʻomohala wikiwiki ʻana o ka ʻoihana kūkulu, ke piʻi nei ka noi o nā kānaka no nā mea hale hou i kēlā me kēia lā, ma muli o ka piʻi ʻana o ka ʻike o ka poʻe i ka mālama ʻana i ke kaiapuni a me ka hoʻomau mau ʻana o ka hana ʻana, ua hoʻomohala wikiwiki ʻia nā huahana gypsum cementitious. I kēia manawa, ʻo nā huahana gypsum maʻamau he stucco gypsum, gypsum i hoʻopaʻa ʻia, gypsum i hoʻokomo ʻia, gypsum i hoʻopili ʻia.
ʻO Stucco plaster kahi ʻano maikaʻi o ka paia o loko a me ka mea hoʻopalapala hale, me ka holoi ʻana i ka paia he palupalu a maʻemaʻe, ʻaʻole pauka, paʻa paʻa me ke kumu, ʻaʻohe haki ʻana, a he hana pale ahi; ʻO ka gypsum adhesive kahi ʻano hou o ka hale paʻa papa kukui, ʻo ia ka gypsum e like me ke kumu kumu, me ka hoʻohui ʻana i nā ʻano mea hoʻohui a hana ʻia i nā mea adhesive, kūpono ia no nā ʻano mea pā hale inorganic ma waena o ka mea paʻa, me nā mea ʻawaʻawa ʻole, ʻono ʻole, ikaika wikiwiki ka hoʻonohonoho ʻana, ka hoʻopaʻa ʻana a me nā ʻano ʻē aʻe, ʻo ia ka papa kūkulu hale, nā mea kākoʻo kūkulu hale; ʻO Gypsum sealant ka mea e hoʻopiha ai i ke āpau ma waena o nā papa gypsum a me ka hoʻoponopono ʻana i ka pā a me nā māwae.
Loaʻa i kēia mau huahana gypsum nā ʻano hana like ʻole, ma kahi o ka gypsum a me nā mea hoʻopihapiha pili e pāʻani ana i kahi kuleana, ʻo ke kumu nui ʻo ia ka hoʻohui ʻana o ka cellulose ether additives i ke alakaʻi. No ka mea, ua puunaue ʻia ʻo GESSO i ke keneta o ka GESSO ANHYDROUS a me ka HEMIHYDRATE GESSO, ʻokoʻa ka hopena GESSO i ka hana o ka huahana, no laila ka mānoanoa, ka mālama wai, ka hoʻonohonoho lohi e hoʻoholo i ka maikaʻi o nā mea hana hale GESSO. ʻO ka pilikia maʻamau o kēia mau mea ʻo ia ka pahu pahu pahu, ʻaʻole hiki i ka ikaika mua i kēia pilikia, e hoʻoponopono i kēia pilikia, ʻo ke koho ʻana i ke ʻano o ka cellulose a me ka retarder compound hoʻohana pilikia pilikia, ma kēia ʻano, ke koho maʻamau o ka methyl a i ʻole. hydroxypropyl methyl cellulose HPMC 30000– 60000CPS, hoʻohui i waena o 1.5‰–2‰, cellulose mai ka nānā ʻana i ka wai hoʻopaʻa ʻana i ka lubrication retarding.

Eia naʻe, ma kēia kaʻina hana, ʻaʻole hiki ke hilinaʻi i ka cellulose ether ma ke ʻano he retarder, a pono e hoʻohui ʻia ka citric acid retarder i ka hui ʻana i ʻole e hoʻopilikia ʻia ka ikaika mua.
ʻO ka nui o ka paʻa ʻana o ka wai e pili ana i ka nui o ka nalowale wai maoli me ka ʻole o ka hoʻoheheʻe ʻana o ka wai i waho. Inā maloʻo ka pā, ʻoi aku ka wikiwiki o ka hoʻoheheʻe ʻana o ka wai ma lalo o ka wai a me ka hoʻoheheʻe maoli ʻana i ka wai, a e loaʻa pū kekahi pahu pahu a me nā ʻano haʻalulu.
ʻO kēia ʻano hoʻohana no ka pauka maloʻo i hui pū ʻia, inā hiki ke kuhikuhi i ka hopena i ke ʻano hoʻomākaukau hoʻonā.

5. ʻO ka mīkini hoʻoheheʻe wela
ʻO ka mortar hoʻoheheʻe wela he mea hoʻopololei pā hou ma ka ʻākau o Kina. He mea pā ia i hoʻohui ʻia e ka mea hoʻoheheʻe wela, ka mortar a me ka binder. Ma kēia mea, he kuleana koʻikoʻi ka cellulose i ka hoʻopaʻa ʻana a me ka hoʻonui ʻana i ka ikaika. ʻO ka maʻamau, koho ʻia ka methyl cellulose me ka viscosity kiʻekiʻe (ma kahi o 10000cps), a ʻo ke ʻano maʻamau ma waena o 2‰ a me 3‰. ʻO ke ʻano o ka hui ʻana i ka pauda maloʻo.

6, mea hoʻohana pili
ʻO ke koho ʻana o ka mea hoʻohana i ka HPMC20000cps, ke koho ʻana i ka tile binder ma mua o 60000CPS, i ka mea hoʻopili kikowaena e nānā ana i ka mea mānoanoa, hiki ke hoʻomaikaʻi i ka ikaika tensile a me ka ikaika pua a me nā hopena ʻē aʻe.
