E HOOMAU ANA I KA AUAU E HELE LOA I keia manawa.

2, ʻoki ʻana 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 lepo o ka helu bibulous he 13%, ʻo 3-5%) ka pahu, hui pū me ka evaporation o ka honua i waho, no laila inā ʻoluʻolu me ke keiki. ʻOi aku ka wikiwiki o ka lilo ʻana o ka wai, e alakaʻi i ka māwae a i ʻole ke ʻano 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 maoli ka ikaika loa, pono e hana i ka sima hydration hopena loa, o ka oi aku i ke kauwela, i ke kukulu ana i ka mīkini palaki wai poho wikiwiki loa, piha hydrated ana ma ka hoola ana i ka wai, keia ala mea he neoneo o ka wai punawai a. ʻO ka hana kūpono ʻole, aia ke kī ma luna o ka ʻili, ʻaʻole i pau ka wai a me ka hydration, no laila nā ala e hoʻoponopono ai i kēia pilikia, I ka mortar concrete e koho maʻamau e hoʻohui i ka hydroxypropyl methyl cellulose a i ʻole methyl cellulose, nā kikoʻī viscosity ma waena o 20000-60000CPS, hoʻohui. ma kahi o 2‰–3‰, hiki ke hoʻonui ʻia ka nui o ka mālama ʻana i ka wai ma mua o 85%, ʻo 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 hoʻopili ʻia, gypsum i hoʻopili ʻia.
ʻO Stucco plaster kahi ʻano maikaʻi maikaʻi o ka paia o loko a me ka mea e hoʻopili ai i ka hale, me ka holoi ʻana i ka paia he palupalu a maʻalahi, ʻaʻole pauka, paʻa paʻa me ke kumu, ʻaʻohe mea ʻokiʻoki, 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, e hoʻohui ana i nā ʻano mea hoʻohui like ʻole 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 hoʻopiha no ka 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, ma ke kikowaena kikowaena e nānā ana i ka mānoanoa mānoanoa, hiki ke hoʻomaikaʻi i ka ikaika tensile a me ka ikaika pua a me nā hopena ʻē aʻe.
