1. ʻO kēia huahana he meaʻawaʻawaʻole, hoʻonāukiukiʻole, he wai maikaʻi ka wai, hiki ke hoʻoheheʻeʻia i ka wai a me nā mea hoʻoheheʻeʻokoʻa likeʻole, a he mea waiwai nui ia no ka hanauna hou o nā mīkini kāpili kiʻekiʻe.

2. He haiki ka puunaue kaumaha mole o keia huahana, he ha'aha'a ka ma'i'o o ka polyethylene glycol, he ki'eki'e ka pa'a pa'a o na kaula palua, a ua ho'omaika'i nui 'ia ka hana polymerization.He kiʻekiʻe ka helu hoʻololi o ka huahana.ʻOi aku ka maikaʻi o ka hana holoʻokoʻa o ka luna.3. ʻO ka mea hoʻohaʻahaʻa wai i hoʻohui ʻia e kēia huahana he kiʻekiʻe-efficiency particle dispersion a me ka paʻa paʻa, a he hopena maikaʻi ka hoʻopuehu ʻana i nā mea pauka he nui e like me ka sima.He kiʻekiʻe ka hoʻohaʻahaʻa wai a me ka hoʻohana haʻahaʻa.ʻO ka maikaʻi o ka sima i hoʻohui ʻia ʻo 0.2% -0.5% ʻO ka mea hoʻohaʻahaʻa wai paʻa, hiki ke hōʻemi ʻia ka wai ma mua o 30%.

4. Ma hope o ka hoʻohui ʻana i ka mea hoʻohaʻahaʻa wai i ka pahu, ua hana ʻia kahi kiʻiʻoniʻoni adsorption ma ka ʻili o nā ʻāpana sima, kahi e hoʻolōʻihi ai i ka hydration rate o ka sima, ʻoi aku ka maikaʻi o ka ulu ʻana o ke aniani pōhaku sima, e hōʻemi ana i nā capillary voids o ka wai. evaporation, a ʻoi aku ka paʻakikī o ka hoʻolālā pūnaewele, hiki ke hoʻomaikaʻi i ka ʻuala ʻOi aku ka ikaika ma mua o 20%.Hiki ke hoʻohana ʻia i ka pāpaʻi pāʻoihana kiʻekiʻe (ma luna o C60).

5. ʻO ka mea hoʻohaʻahaʻa wai i hoʻohui ʻia e kēia huahana hiki ke hoʻomaikaʻi maikaʻi i ka rheology a me ka plasticity o ke kaila.Hiki iā ia ke hoʻokō i ke kūkulu ʻia ʻana ma o ke kahe ponoʻī ʻana, pumping, a me ka haʻalulu ʻole, hiki ke hoʻonui i ka wikiwiki o ke kūkulu ʻana a hoʻemi i ke kumukūʻai kūkulu.

6. ʻO kēia huahana he'ōmaʻomaʻo'ōmaʻomaʻo a me ke kaiapuni, chloride ion content: ≤0.1%.E hoʻokō me nā kūlana hoʻokele mālama kaiapuni honua ISO14001.

1. Loaʻa i kēia huahana ka hoʻoheheʻe wai maikaʻi.

2. Hoʻohana kēia huahana i ka catalyst ikaika a me kahi kaʻina hana synthesis kūikawā.He haiki ka puunaue paona mole, he haahaa ka nui o ka ethylene glycol, a he kiekie ka paa paa palua.Hoʻomaikaʻi maikaʻi ʻia ka hana polymerization, kiʻekiʻe ka nui o ka hoʻololi ʻana o ka huahana, ʻo ka polycarboxylic acid water reducer product synthesized by the product has high effective content, a ʻo ka mea hoʻemi wai he hana maikaʻi loa.

3. Ka helu hana a me ka maikaʻi o ka mea hoʻemi wai synthetic:

1) Hana uku kiʻekiʻe.Ma ka hihia o ka loaʻa ʻana o ka hoʻēmi wai like, loaʻa iā ia kahi hana kiʻekiʻe.

2) Hoʻohui haʻahaʻa a me ka hoʻohaʻahaʻa wai kiʻekiʻe.ʻO ka waiʻona makuahine hoʻohaʻahaʻa wai me ka maʻi paʻa o 20% a me ka nui o ka hoʻohaʻahaʻa wai o 1.0% (ka nui o nā mea cementing) hiki ke hiki i 30-35%.

3) Paʻa maikaʻi i ka plasticity.He liʻiliʻi ka hāʻule ʻana o ke koki ma hope o 1h.

4) Kūlana maikaʻi loa.Hiki ke hōʻemi nui i ka hoʻohana ʻana i ka wai a hoʻomaikaʻi i ka lōʻihi o ke kaʻa.

5) ʻO ka'ōmaʻomaʻo a me ke kaiapuni.I ke kaʻina hana o ka hoʻohaʻahaʻa wai, ʻaʻohe formaldehyde a me ka chloride ion e hōʻino i ke kaiapuni, a haʻahaʻa ka ʻike o ka sulfate.
