Pehea e hoʻomaikaʻi ai i ke kūkulu ʻana o ka cellulose ma ka pā wela wela i ke kauwela

I kēia manawa, ua kokoke e komo i ke kauwela, a he kiʻekiʻe ka mahana, ʻoi aku ka nui ma ka ʻāina ʻākau.He kiʻekiʻe ka mahana a maloʻo ka ea.Hiki ke piʻi ka mahana wela o ka pā i 60°C.Ma muli o ka mahana, pilikia pinepine ka cellulose e like me ka hana maikaʻi ʻole a me ka wehe ʻana i ka pauka i ka wā o ke kūkulu ʻana.ʻO ke kumu nui ma muli o ke kiʻekiʻe o ka wela o ka pā, ʻaʻole maikaʻi ka paʻa ʻana o ka wai o ka putty, no laila e hoʻopili koke ʻia ka wai i loko o ka putty e ka paia, i ʻole hiki ke hoʻopili pinepine ʻia ka putty.Hōʻike ʻia ka hollowing a me ka ʻili.Pehea e hoʻomaikaʻi ai i ka paʻa ʻana o ka wai o ka pauka o waho o ka pā putty i ka nui o nā ʻano penei:

1. Hoʻonui i ka nui o ka cellulose ether

Loaʻa i ka cellulose ether ka paʻa wai maikaʻi, akā ʻaʻole e hoʻonui ka hana paʻa wai ma hope o ka hoʻohui ʻia ʻana o ka cellulose ether.I ka manawa like, hoʻonui ka cellulose i ka viscosity o ka putty a ʻaʻole maʻalahi ke kūkulu ʻana.Eia kekahi, hoʻonui ke kumukūʻai o ka putty.

2. E hoʻonui i ka lignoscellulose

Loaʻa i ka Lignocellulose kekahi hopena paʻa wai.ʻO ka hoʻohui ʻana o ka lāʻau fiber e hoʻomaikaʻi i ka mana paʻa wai o ka mea, hana i ka ʻōnaehana waiwai hydrated like, a hiki ke hoʻomaikaʻi i ka workability i ka manawa like, akā ʻokoʻa ke kumu mālama wai o ka lignoscellulose mai ka cellulose.Loaʻa iā ia ke ʻano o ka lawe ʻana i ka lauoho.(Water conduction), aia ka makū ma waena o kēlā me kēia fiber, a i ka wā e hoʻololi a emi iho ai ka makū ma ka puni a puni o ka fiber, e hoʻokuʻu like ʻia ka wai ma waena o nā fiber.ʻO ka manawa wehe, ʻaʻole maʻalahi ka haki.Eia naʻe, no ka lahilahi o ka mānoanoa o ka putty ma ka paia o waho, ʻo 0.5-1mm wale nō ka mānoanoa o kēlā me kēia ʻōpala.Ke kiʻekiʻe ka wela o ka ʻili o ka papa kumu a me ka mahana o ka ea, ʻaʻole maopopo ka hana o ka mālama ʻana i ka wai, a ʻoi aku ka awelika o ka hana ʻana o ka uhi ʻana.

3. Hoʻonui i ka nui o ka polymer

Ma nā paia me ka putty thinner, ka ea maloʻo a me ke kiʻekiʻe o ka wela kumu, ʻo ka hoʻonui ʻana i ka nui o ka polymer ʻo ia kekahi o nā ala maikaʻi loa e hana ai i ka putty i ka ʻoki ʻana i nā waiwai, akā kiʻekiʻe ke kumukūʻai o ka pauka latex redispersible, e hoʻonui nui ʻia ka nui. ke kumukuai o ka putty.Hiki iā ia ke pāʻani i kahi ʻoi aku ka maikaʻi ma ka hoʻohui ʻana i kahi liʻiliʻi o ka pauka waiʻona polyvinyl, akā ʻoi aku ka nui o ka viscosity o ka pauka polyvinyl alcohol, kahi e hoʻopilikia ai i ka hana, a ʻaʻole maikaʻi ka waiwai sanding o ka putty..

4. Hoʻohui i ka lubricant polymer

Ma o ka hoʻāʻo ʻana, manaʻo ʻia he koho maikaʻi loa ia e hoʻohui i kahi lubricant kiʻekiʻe i ka putty pā waho i loko o ke kaiapuni o ka wela kiʻekiʻe i ke kauwela.ʻO ka lubricant no ka polymer compound, a ʻo ka rheological lubricant ka mea nui e hoʻomaikaʻi i ka hana hana i loko o ka ʻōnaehana sima.Wehe manawa a me ka hana mau.Hoʻonui i ka hana a me ka sag kū'ē o nā mortar, plasters, renders, plasters and adhesives a pale aku i ka delamination o ka sima hoʻonaʻauao ponoʻī.ʻO ke kumu o ka paʻa ʻana o ka wai ʻo ia ka nui o nā pūʻulu hana hydrophilic ma kāna kaulahao mole.I ka hihia o ka hoʻopaʻa pinepine ʻana a me ka uhi ʻana, ʻaʻole ia e nalowale i ka wai, loaʻa ka hana paʻa wai koʻikoʻi, a he mānoanoa a me ka thixotropy i ka manawa like, e ʻoi aku ka maʻalahi o ke kūkulu ʻana a hiki ke hoʻololi i ka cellulose, akā ʻo kona kumukūʻai he cellulose ether wale nō, a ʻO kāna dosage he 0.1-0.2%., He mea waiwai loa ia, inā hoʻohana pū me ka cellulose ether, lignoscellulose, a me ka pauka latex redispersible, e ʻoi aku ka maikaʻi o ka hopena.
