ʻO nā pilikia maʻamau a me nā ʻano ʻike o ka pauka latex redispersible

Me ka hoʻomohala wikiwiki ʻana o ka mākeke mālama ola hale hale, ʻoi aku ka nui o nā R&D a me nā ʻoihana hana i komo i ka R&D a me ka hana ʻana i nā huahana polymer pauka redispersible, a ʻoi aku ka nui o nā mea hoʻohana no ke koho, akā i ka manawa like, ka ʻO ka maikaʻi o ka pauka polymer redispersible ua lilo ʻole. , nā iʻa hui ʻia a me nā ʻīlio hae. I mea e hōʻemi ai i nā kumukūʻai, ʻaʻole i mālama kekahi mau mea hana i nā kūlana maikaʻi, maikaʻi ʻole e like me nā mea maikaʻi, a hoʻohana kekahi i nā pauka resin maʻamau e like me nā pauka latex redispersible e kūʻai aku ma nā kumukūʻai haʻahaʻa ma lalo o ke ʻano o nā pauka latex redispersible, ʻaʻole ia e hoʻopilikia wale i ka mākeke akā. hoʻopunipuni ka mea kūʻai. Akā, i loko o ka mākeke hoʻokele waiwai kahi e ola ai ka poʻe kūpono, ʻo ka maikaʻi ke kumu o ka hoʻomohala hoʻomau, a ʻaʻole hiki ke uhi ʻia ke koloka hoʻokamani. Ma kahi huaʻōlelo: ʻo ka maikaʻi ka pānaʻi o ke kumukūʻai, ʻo ka brand ka lepili o ka maikaʻi, a ʻo ka mākeke ke kūlana hoʻāʻo hope loa.

◆ ʻO ka mea mua, e noʻonoʻo kākou i nā pilikia maʻamau o ka pauka latex redispersible, a me nā ala maʻamau a me nā pōʻino o nā mea hana hewa ʻole e hōʻemi i nā kumukūʻai:

◆ Pehea e ʻike ai a ʻike paha i ka maikaʻi o ka pauka latex redispersible? No ka huli ʻana i kahi ala, e hoʻomaka me ka nānā ʻana:

1. Nānā i nā hōʻailona hana

ʻO nā hōʻailona ke kumu no ke ana ʻana i ka maikaʻi o ka pauka latex redispersible. ʻO ka papa kuhikuhi maʻamau ka helu helu o ka hana maʻamau o ka pauka polymer redispersible. Inā ʻoi aku ka nui o ka papa kuhikuhi o ka pauka polymer redispersible a ʻaʻole i hoʻokō i ka maʻamau, e loaʻa ka hopena pololei i kāna hana. ʻO nā kumu nui o nā hōʻailona maʻamau ka pilikia o ka hana ʻana, e like me ka ʻenehana hana hope, nā mea kahiko a i ʻole nā ​​​​mea kahiko, ka hoʻohana ʻana i nā kumu waiwai haʻahaʻa a haʻahaʻa, a me ka nānā ʻana o ka hale hana lax o nā huahana i hoʻopau ʻia. ʻO ka mea hou aku, he manawa kūpono kekahi mau mea hana i mea e hōʻemi ai i nā kumukūʻai, me ka nānā ʻole i ka maikaʻi, a me ka maikaʻi. No laila, pono e koho i kahi mea hana maʻamau a hilinaʻi.

2. Ke kālailai hana kumu

1. Redispersibility: hiki ke hoʻoheheʻe ʻia ka pauka latex me ka redispersibility maikaʻi i loko o ka wai e hana i kahi emulsion paʻa, a ua like ka puʻupuʻu nui me ka emulsion kumu. ʻO ka pauka Rubber me ka maikaʻi ʻole o ka redispersibility, ʻaʻole hiki ke hoʻololi like ʻia, a hiki ke loaʻa i nā polymers hiki ʻole ke redispersible.

2. Nā waiwai hana kiʻiʻoniʻoni o ka pauka rubber: ʻO nā waiwai hana kiʻiʻoniʻoni ke kumu o nā waiwai hoʻololi mortar e like me ka adhesion. ʻO nā waiwai hana kiʻiʻoniʻoni maikaʻi ʻole ke kumu ma muli o ka hoʻohui nui ʻana i nā ʻāpana inorganic a i ʻole nā ​​​​mea kūlohelohe kūpono ʻole. Loaʻa nā waiwai hana kiʻiʻoniʻoni maikaʻi ma ka lumi wela, a ʻo ka poʻe me nā waiwai hana kiʻiʻoniʻoni maikaʻi ʻole i ka lumi wela ka hapa nui o nā pilikia maikaʻi e pili ana i ka polymer a i ʻole ka lehu.

3. ʻO ke kūpaʻa wai o ke kiʻiʻoniʻoni: ʻO ka pauka Latex Redispersible he mau waiwai hana kiʻiʻoniʻoni maikaʻi a maikaʻi hoʻi ke kūpaʻa wai. ʻO nā pauka Latex me ke kūpaʻa wai maikaʻi ʻole ka nui o nā polymers hiki ke hoʻoheheʻe wai.

3. Ka noiʻi hopena hopena

Hoʻoholo ʻia e like me ke kūlana kūpono:

1. ʻO ka ikaika paʻa maloʻo a me ka ikaika paʻa paʻa wai: ʻaʻole maikaʻi ka paʻa, a aia nā pilikia maikaʻi e pili ana i ka polymer a i ʻole ka lehu.

2. ʻO ka maʻalahi a me ka pale ʻana i ka hopena: ʻAʻole maikaʻi ka maʻalahi, aia nā pilikia maikaʻi i ka polymer, a ke emi nei ka maʻalahi i ka wā o ka hoʻohana ʻana, aia paha nā plasticizers.

3. Hydrophobic a me ka non-hydrophobic: He hydrophobic loa ka ʻili, hiki ke hoʻemi i ka hana a me ka ikaika paʻa o ka mortar.

4. Kahe a me ka rheology: ʻAʻole maikaʻi ka rheology, a aia nā pilikia maikaʻi i nā polymers a i ʻole nā ​​mea hoʻohui.

5. Ka hu'a a me ka ho'oha'aha'a: 'O ka hana hu'ahu'a ma'amau, nā pilikia maika'i me nā polymers, ka lehu a me nā mea ho'ohui.

◆ He mau ala maʻalahi e ʻike ai i ka pauka latex redispersible:

1. Keʻano o keʻano: e uhi i kahi liʻiliʻi o ka pauka latex redispersible me ka lahilahi a me ke kaulike ma luna o ka ili o ka ipu aniani maʻemaʻe me ke koʻokoʻo aniani, e kau i ka pā aniani ma ka pepa keʻokeʻo, a nānā pono i keʻano o nā'āpana, nā mea'ē a me ka coagulation.

2. Keʻano hoʻoheheʻe: E lawe i kahi liʻiliʻi o ka pauka latex redispersible a hoʻokomo i loko o 5 manawa o ka wai, e hoʻoulu mua a kali no 5 mau minuke e ʻike. Ma ke kumu, ʻoi aku ka liʻiliʻi o ka mea hiki ke hoʻoheheʻe ʻia i ka papa lalo, ʻoi aku ka maikaʻi o ka pauka latex redispersible.

3. Lehu ala: E lawe i kekahi nui o ka redispersible latex pauda, ​​e kaupaona ia, e waiho ia i loko o ka metala ipu, e wela ia ma kahi o 600 degere, puhi ia ma ke kiʻekiʻe wela no ma kahi o 30 minuke, hooluolu i ka lumi wela, a kaumaha ia. hou. Maikaʻi maikaʻi no ke kaumaha māmā.

4. Kiʻiʻoniʻoni ʻano hana: E lawe i kahi nui o ka pauka latex redispersible, e hoʻokomo i loko o 2 mau manawa o ka wai, e hoʻoulu like, e kū no 2 mau minuke, e hoʻoulu hou, e ninini mua i ka hopena ma ke aniani pālahalaha, a laila ke aniani Kau. ia ma kahi malu ea. Ma hope o ka maloʻo ʻana, e nānā i ka maikaʻi me ke aniani kiʻekiʻe.
