ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiahe pauka redispersible wai, ʻo ka mea maʻamau ka ethylene-vinyl acetate copolymer, a hoʻohana i ka waiʻona polyvinyl ma ke ʻano he colloid pale. No laila, kaulana loa ka pauka polymer redispersible i ka mākeke ʻoihana kūkulu. Akā ʻaʻole maikaʻi ka hopena o ke kūkulu ʻana i ka pauka polymer redispersible ma muli o ke koho kūpono ʻole. No laila he mea nui e koho i ka pauka polymer redispersible pono, pehea e ʻike ai a koho i ka pauka polymer redispersible?

Ke ala no ka ʻike ʻana i ka pauka polymer redispersible

1. E hoʻohui i ka pauka polymer redispersible me ka wai i ka ratio o 1: 5, e hoʻoulu like a waiho i 5 mau minuke, a laila e nānā i ka sediment ma ka papa lalo. ʻO ka maʻamau, ʻo ka liʻiliʻi o ka sediment, ʻoi aku ka maikaʻi o ka RDP.

2. Huika pauka polymer redispersibleme ka wai i ka ratio o 1: 2, e hoʻoulu like, e kū no 2 mau minuke, a laila e hoʻoulu like, e ninini i ka hopena ma kahi aniani maʻemaʻe pālahalaha, e kau i ke aniani i loko o ka malu ventilated, ma hope o ka maloʻo pihaʻana, eʻoki i ka uhi ma luna. ke aniani a nānā i ke kiʻi polymer. ʻO ka ʻoi aku ka maopopo, ʻoi aku ka maikaʻi o ka pauka polymer redispersible. Huki pono i ke kiʻiʻoniʻoni. ʻOi aku ka maikaʻi o ka elasticity, ʻoi aku ka maikaʻi o ka maikaʻi. Eʻoki i ke kiʻiʻoniʻoni i loko o nā'āpana. Hoʻopili ʻia i ka wai, a nānā ʻia ma hope o 1 lā, ʻoi aku ka liʻiliʻi o ka dissolved, ʻoi aku ka maikaʻi o ka maikaʻi.

3. E lawe i ka nui kūpono o ka pauka polymer no ke kaupaona ʻana, e hoʻokomo i loko o kahi pahu metala ma hope o ke kaupaona ʻana, e wela iā ia ma kahi o 500 ℃, e puhi iā ia i kahi wela kiʻekiʻe o 500 ℃, a laila e kaupaona ma hope o ka hoʻoilo. ʻOi aku ka māmā o ke kaumaha, ʻoi aku ka maikaʻi.

4. Ho'āʻo kāpili me ka pahu pahu a i ʻole veneer. E lawe i ʻelua mau ʻāpana pahu pahu a i ʻole ka papa lahilahi o ka nui like, a hoʻopili i ke kāpili i ke kikowaena o ka hāpana. Ma hope o 30 mau minuke o ke kaomi ʻana i ka mea, e lawe i waho no ka nānā ʻana. Inā hiki ke hoʻopaʻa paʻa ʻia a hoʻopau ʻia ke kikowaena 100%, ʻoi aku ka maikaʻi o ka RDP. Inā hiki ke hoʻopau wale ʻia ke kikowaena, ʻo ia ka mea ʻaʻole maikaʻi loa ka ikaika adhesive o RDP a ʻaʻole kūpono ka maikaʻi. Inā paʻa ka interface a ʻaʻole i pōʻino, ʻo ia ka mea haʻahaʻa a hoʻopunipuni.

Ke ala no ke koho ʻana i ka pauka polymer redispersible

1. ʻO ka mahana hoʻololi aniani (TG) o ka pauka polymer redispersible. ʻO ka mahana hoʻololi aniani kahi hōʻailona koʻikoʻi o nā waiwai kino o RDP. No kahi huahana kiko'ī, he mea pono ke koho kūpono o ke aniani hoʻololi wela (TG) o ka RDP e hoʻonui i ka maʻalahi o ka huahana a pale i nā pilikia e like me ka haki.

2. Hoʻoheheʻe hou.

3. Ka wela hana kiʻiʻoniʻoni liʻiliʻi loa (MFFT). Ma hopeka pauka polymer redispersibleua hui pū ʻia me ka wai a hoʻoulu hou ʻia, loaʻa iā ia nā waiwai like me ka emulsion mua, ʻo ia hoʻi, e hana ʻia kahi kiʻiʻoniʻoni ma hope o ka haʻalele ʻana o ka wai. ʻO ke kiʻiʻoniʻoni he kiʻekiʻe ka maʻalahi a me ka hoʻopili maikaʻi ʻana i nā ʻano substrates.

ʻO ka mea i luna ke ala e ʻike ai i ka pauka polymer redispersible a koho i ka pauka polymer redispersible. Ua ʻike ka poʻe i ka ʻoihana kūkulu hale i ka RDP ma ke ʻano koʻikoʻi o Building Construction Chemical. ʻO ka maikaʻi o ka pauka polymer pili pono i ka maikaʻi a me ka holomua o ka hana. He mea nui e koho i ka pauka polymer redispersible kūpono.
