Ua ʻōlelo ʻo TH-928 wai hana kiʻekiʻe polycarboxylic–reduchoʻohuihui (OPQC moo hoemi wai)
TH – 928 ʻO ka polycarboxylic acid kahi ʻano hana kiʻekiʻe hou
mea hoemi wai he nui na waiwai. Aia ia ma ke alo o ka honua; loaʻa iā ia nā pae kiʻekiʻe o ka ʻepekema a me ka ʻenehana; loaʻa iā ia ka manaʻolana noi maikaʻi loa. ʻO kēia mau mea a pau e lawe mai iā ia i mea hoʻoheheʻe super plasticizer (mea hoemi wai) me nā waiwai piha maikaʻi loa.
TH – 928 ʻO ke keʻena o ka poly carboxylic acid ka mea hana hoʻohaʻahaʻa wai hana kiʻekiʻe he ʻano carboxylic acid ʻano huahana copolymer lehulehu.. Hoʻohālikelike i nā hana ʻē aʻe o nā huahana like ma ka home a ma waho, e hoike mai ana o TH – 928 ʻO ka poly carboxylic acid kahi mea hana hoʻohaʻahaʻa wai kiʻekiʻe i nā hōʻailona hana ʻenehana, ka mea i hiki i ka hana / kumu kūʻai lākiō ma ka pae kiʻekiʻe honua o kēia lā.

hoʻohuihui?
1. Ke loaʻa nā mea haʻahaʻa haʻahaʻa a me ka nui o ka emi ʻana o ka wai, aia i ka 45%;
2. I ka wā e māmā ai ka hāʻule, he uuku kona poho. ʻOi aku ka liʻiliʻi o ka hāʻule ʻana o ka slump pohō o ka mea i hoʻohui ʻia 5% i ka hora 1 a 10% i ka hola 2;
3. He hopena hoʻonui nui: hoʻonui ʻia ka ikaika compressive 3d concrete ma 50-110%, 28d piʻi ka ikaika compressive e 40-80%, 90d ikaika compressive i hoʻonui ʻia e 30-60%;
4, Maikaʻi ka hana paʻa. ʻAʻohe ʻano hoʻokaʻawale a me ke koko. ʻAʻahu like ke kala hiʻohiʻona. I ka TH-928 polycarboxylic kiʻekiʻe-hana hoʻohaʻahaʻa wai admixture
hoʻohana ʻia e hoʻomākaukau i ke kiʻekiʻe kiʻekiʻe, maikaʻi ka hui ʻana o ke koʻi a maʻalahi ke hui.
5. Loaʻa iā ia ka ea maʻamau. ʻAʻohe hopena maikaʻi ʻole i ka modulus elastic elastic. aka, maikaʻi ka hau a me ka lōʻihi;
6, Hiki iā ia ke hoʻemi i ka wela hydration mua o ka sima, no laila ua kūpono ia i ke kūkulu ʻana i ke kaʻa a me ke kauwela;
7. Loaʻa iā ia ke kūpono kūpono, kūpono maikaʻi o ka sima a me ka hoʻohui, maikaʻi ka hoʻololi wela, kūpono maikaʻi me nā ʻano ʻano sima a me nā mea hoʻohui, ka mea e hoʻoponopono ai i ka pilikia o ka hoʻohālikelike maikaʻi ʻole ma waena o nā ʻano mea hoʻohaʻahaʻa wai a me nā mea hana sima;
8, Loaʻa iā ia ka hiki ke emi haʻahaʻa, hiki ke hoʻemi nui i ka shrinkage koneki. ʻOi aku ka maikaʻi o kona kūpaʻa hau a me ka hoʻoheheʻe ʻana a me ka carbonization ma mua o ke kaila maʻamau. He aha hou aku, it significantly improve concrete volume stability and long-term durability.
9. Ma muli o kona haʻahaʻa haʻahaʻa alkali (maʻiʻo alkali ≤0.2%) , hiki iā ia ke pale pono i ka loaʻa ʻana o ka hopena aggregate alkali
10. Ma muli o ke kūpaʻa maikaʻi o nā huahana, ʻaʻohe stratification a me ka ua i ka mālama lōʻihi, ʻaʻohe crystallization ma ka wela haʻahaʻa;
11. ʻO nā huahana he mea aloha kaiapuni a ʻaʻohe formaldehyde.
12, Loaʻa iā ia nā pono waiwai maikaʻi. ʻOi aku ka haʻahaʻa o kāna kumukūʻai piha o ka papahana ma mua o ka hoʻohana ʻana i nā ʻano huahana ʻē aʻe. He aha hou aku, ma lalo o ke kūlana ikaika like, hiki i ka TH-928 polycarboxylic kiʻekiʻe ka hana hoʻohaʻahaʻa wai hoʻohuihui hiki ke mālama 15-25% o ka sima.
Nā hōʻailona ʻenehana o ka TH-928 wai hana kiʻekiʻe polycarboxylic–reduchoʻohuihui
ʻO ka ʻike o waho o ka TH-928 polycarboxylic hana kiʻekiʻe ka hoʻohaʻahaʻa wai hoʻohuihui he wai ʻeleʻele māmā.
Kona Paa (g/ml) he 1.09±0.02
Kona maʻiʻo paʻa (%) he 22±2
ʻO kāna ʻupena pāpaʻi sima fluidity (sima benchmark) (mm) ʻo ≥ 250 (W/C=0.29)
Aia kona PH i waena 6 ~ 8
ʻO kona ʻano ion Chloride (%) ʻo ≤ 0.02
Kona mea Alkali (Na2O+0.658K2O) (%) ≤ 0.2
Nā kuhikuhi o ka TH-928 wai hana kiʻekiʻe polycarboxylic–reduchoʻohuihui
1. ʻO ka hui hoʻohui 0.4% ~ 2.0% o ka nui o ke kaumaha o na mea hana sima, a ʻo ka hui hoʻohui maʻamau 0.4% ~ 1.2%. Pono e hana ʻia ka hoʻāʻo ʻana ma mua o ka hoʻohana ʻana i mea e hoʻonui ai i ka nui o ka hui ʻana;
2. ʻAʻole hiki ke hoʻohui ʻia me ka moʻo naphthalene o ka mea hoʻemi wai maikaʻi. A e hana mua ʻia ka hoʻāʻo hoʻohālikelike ʻana ma mua o ka hui ʻana me nā mea hoʻohui ʻē aʻe；
3. Hoʻopili nui ka Slump i ka hoʻohana wai, a pono e mālama pono i ka hoʻohana ʻana i ka wai i ka wā e hoʻohana ai;
4. E noʻonoʻo i ka hoʻomaʻemaʻe ʻana i ka ʻili.
ʻO ka palapala noi ka laulā o ka TH-928 wai hana kiʻekiʻe polycarboxylic–reduchoʻohuihui
He kūpono ia no ka pahū ʻana a i ʻole nā hana kuʻuna maʻamau me ka māka ikaika C15 ~ C60 a i ʻole, he mea kūpono loa ia no nā hana koneki me ka hoʻomanawanui kiʻekiʻe, kūlana kahe kiʻekiʻe, pale slump kiʻekiʻe, ikaika kiʻekiʻe a me ke koi kiʻekiʻe no ka maikaʻi o ka helehelena. He aha hou aku, He mea maikaʻi loa ka hoʻomākaukau ʻana i ke kiʻekiʻe fluidity, paʻa paʻa ponoʻī a me ka ʻili wai.
ʻO ka hoʻopaʻa a mālama o ka wai hana kiʻekiʻe polycarboxylic–reduchoʻohuihui
1. ʻO Th-928 polycarboxylic acid series high-performance water reducer he huahana wai, i hookomoia iloko o na barela;
2. E mālama ʻia i loko o kahi ʻauʻau maloʻo a maloʻo, a e pale pono ia i ka malamalama o ka lā a e pale ʻia mai ka hau i ka hoʻoilo;
3. ʻO ka manawa mālama sila 12 mahina. Ma hope o ka pau ʻana o ka manawa, hiki ke hoʻohana i ka wā i hōʻoia pono ai lākou e ʻai.
ʻO Cie-China.org ka mea hoʻolako mea hoʻohui kumu hoʻohāhā nui e hāʻawi ana i ka mea hoʻoheheʻe pahu, superplasticizer,mea hoʻonui i ka ikaika o ka ʻūhā no ka lāʻau māmā, Nā poloka CLC. Inā ʻoe e ʻimi nei superplasticizer, e ʻoluʻolu e ʻoluʻolu kāhea iā mā˚ou.
