Pehea e koho ai i ka pauka polymer redispersible?

ʻAʻohe ala maikaʻi ʻē aʻe ma mua o ka hoʻokomo ʻana i ka huahana i loko o ka hoʻokolohua.

ʻO ke koho ʻana i ka pauka latex redispersible kūpono e noʻonoʻo i kēia mau ʻano:

1. ʻO ka mahana hoʻololi aniani o ka pauka polymer redispersible.

ʻO ka mahana hoʻololi aniani e hōʻike ana ka polymer i ka elasticity; ma lalo o kēia mahana, hōʻike ka polymer i ka brittleness. ʻO ka mahana hoʻololi aniani o ka pauka latex maʻamau -15±5℃, a ʻo ka pauka latex o nā mea hana maʻamau i loaʻa ʻole kēia kuhikuhi. Pilikia. ʻO ka mahana hoʻololi aniani kahi hōʻailona nui o nā waiwai kino o ka pauka latex redispersible. No kahi huahana kiko'ī, hiki i kahi koho kūpono o ka mahana hoʻololi aniani o ka pauka latex redispersible e hoʻonui i ka maʻalahi o ka huahana a pale i nā pilikia e like me ka haki ʻana.

2. ʻO ke kiʻiʻoniʻoni liʻiliʻi loa ka wela

Ma hope o ka hui ʻana o ka pauka latex redispersible me ka wai a hoʻoulu hou ʻia, loaʻa iā ia nā waiwai like me ka emulsion kumu, ʻo ia hoʻi, e hana ʻia kahi kiʻiʻoniʻoni ma hope o ka evaporates o ka wai. ʻO kēia kiʻiʻoniʻoni he kiʻekiʻe ka maʻalahi a me ka hoʻopili maikaʻi ʻana i nā substrate like ʻole. ʻOkoʻa ʻO ka liʻiliʻi liʻiliʻi o ke kiʻiʻoniʻoni o ka pauka latex i hana ʻia e ka mea hana e ʻokoʻa. ʻO 0 ka papa kuhikuhi o kekahi mau mea hana°C, a ʻo ka helu helu o kekahi mau mea hana he 5°C. E like me ka lōʻihi o ka wela hana kiʻiʻoniʻoni o ka pauka latex me ka maikaʻi maikaʻi ma waena o 0 a me 5°C ma waena.

3. Ka hoʻoheheʻe hou ʻana.

ʻO ka pauka latex redispersible haʻahaʻa he hapa a paʻakikī paha i ka wai anuanu a i ʻole ka wai alkaline.

4. Kumukuai.

ʻO ka maʻiʻo paʻa o ka emulsion ma kahi o 53%, ʻo ia hoʻi ma kahi o 1.9 tons o ka emulsion e ho'ōla ʻia i hoʻokahi tona o ka pauka.

Inā helu ʻia he 2% o ka wai, a laila hoʻohana ʻia ka 1.7 tons o ka emulsion e hana i hoʻokahi tona o ka pauka lāʻau, a me 10% o ka lehu,

He 1.5 mau tona o ka emulsion e hana ai i hookahi tona o ka pauda.

5. Hoʻonā wai o ka pauka latex

I mea e ho'āʻo ai i ka viscosity o kaka pauka polymer redispersible, hoʻoheheʻe wale kekahi mau mea kūʻai i ka pauda latex i loko o ka wai a hoʻoluliluli ʻia e ka lima e hoʻāʻo ai, a ʻike ʻia ʻaʻohe paʻa, me ka manaʻo ʻaʻole ia he pauda latex maoli.

ʻO ka ʻoiaʻiʻo, ʻaʻole pili ka pauka latex redispersible, he pauka i hana ʻia ma hope o ka hoʻomaloʻo ʻana o ka polymer emulsion.

Ke hui pū ʻia ka pauka latex redispersible me ka wai a hoʻoulu hou ʻia, loaʻa iā ia nā waiwai like me ka emulsion kumu, ʻo ia hoʻi, ʻo ka kiʻiʻoniʻoni i hana ʻia ma hope o ka evaporates o ka wai he kiʻekiʻe ka maʻalahi a loaʻa ka hoʻopili maikaʻi loa i nā substrates like ʻole.

Hiki iā ia ke hoʻonui i ka paʻa ʻana o ka wai o ka mea, e pale i ka mortar sima mai ka paʻakikī loa, maloʻo a māwae; hoʻonui i ka plasticity o ka mortar a hoʻomaikaʻi i ka hana hana. ʻO ka hoʻopuehu ʻana, nā waiwai hana kiʻiʻoniʻoni, hiki ke maʻalahi (me ka hoʻāʻo huki ʻana, inā paha i kūpono ka ikaika kumu) ma ke ʻano maʻamau, e loaʻa nā hopena hōʻike ma hope o 10 mau lā.
