ʻO ka hana nui o ka Polycarboxylate Superplasticizer Polyether:

1. Nā Waiwai ʻIke ʻia o Polycarboxylate Superplasticizer Polyether:

2. Hoʻopili Hana

(1) Ka maikaʻi loa o ka hoʻopuehu ʻana a me ke kahe ʻana no ka sima ʻoiai ma nā dosages haʻahaʻa; (2) Ka piʻi nui ʻana o ke kahe ʻana o ka paste ke piʻi ka dosage mai 0.12% a i 0.22%; (3) ʻAʻohe nalowale o ke kahe ʻana o ka paste ma hope o 1 hola; (4) ʻOi aku ka nui o ke kahe ma mua o ka pālua o nā mea hoʻemi wai kiʻekiʻe i loaʻa ma ke kālepa.

3. Hana Hana ʻOle

(1) Pili ka nui o ka hoʻemi ʻana o ka wai o ka mortar i ka wai o ka paste: ʻo ke kiʻekiʻe o ka wai o ka paste e alakaʻi i ka nui o ka hoʻemi ʻana o ka wai o ka mortar; (2) Piʻi koke ka nui o ka hoʻemi ʻana o ka wai me ka dosage a noho mau i kahi kiʻekiʻe; ma ka dosage like, ma kahi o 35% ʻoi aku ka kiʻekiʻe ma mua o nā mea hoʻemi wai kiʻekiʻe i loaʻa ma ke kālepa; (3) Hiki ke ʻokoʻa ka nui o ka hoʻemi ʻana o ka wai o ka sima mai ka nui o ka hoʻemi ʻana o ka wai o ka mortar ma muli o ka mana o nā admixtures a me nā waiwai aggregate: inā hoʻonui nā admixtures a me nā aggregates i ka wai o ka sima, e ʻoi aku ka nui o ka hoʻemi ʻana o ka wai o ka sima ma mua o ka mortar; inā ʻaʻole, e haʻahaʻa ia; (4) Hana antifreeze i nā mahana ma luna o -5 ℃, kūpono no ka hoʻohana ʻana ma ke ʻano he mea antifreeze i loko o ka sima.

4. Hana ʻana o ka Polycarboxylate Superplasticizer Polyether Concrete

(1) Ikaika o ka Pākuʻi Lākiō o ka hui pākuʻi (kg/m³):

Ka lakio ulu ikaika compressive (vs. kuhikuhi) (%):

(2) Waikawa Polycarboxylic Sodium Paʻakai Nā Waiwai ʻē aʻe o ka Concrete

ʻO ka sima i kāwili ʻia me ka mea hoʻēmi wai pauka he haʻahaʻa ka nui o ke kahe ʻana a me ka nui o ka emi ʻana ma mua o ka sima kuhikuhi; ua hoʻolōʻihi ʻia ka manawa hoʻonohonoho mua ma kahi o 60 mau minuke i hoʻohālikelike ʻia me ka kuhikuhi, ʻoiai ua aneane like ka manawa hoʻonohonoho hope loa; ʻo ka nui o ka ea i kāohi ʻia ma 2-4%.

Ka nui i ʻōlelo ʻia:

Ka nui i ʻōlelo ʻia no ka sima: 0.1~0.25% o ka nui o ka sima. ʻO ka mea hoʻēmi wai he pauka me ka polycarboxylate ma ke ʻano he mea nui (ʻike paʻa ~98%). ʻO ka nui maʻamau he 0.12%–0.3%:

Ma kahi mahele o 0.06% wale nō, loaʻa iā ia kahi helu hōʻemi wai 12% a me ka ulu ʻana o ka ikaika 23%, e ʻoi aku ka maikaʻi ma mua o nā mea hoʻopumu maʻamau i loaʻa ma ke kālepa;

Ma ka mahele lāʻau 0.1%, ʻoi aku ka hana ma mua o nā mea hoʻemi wai kiʻekiʻe e pili ana i ka naphthalene a me ka melamine;

Ma lalo o 0.14% dosage, ʻaʻole koʻikoʻi ka ʻoi aku ka maikaʻi o ka hana;

Ma luna o 0.20% dosage, hiki i ka hana sima a me ka pumpability i kahi pae maikaʻi loa.

ʻO ka nui kūpono i ʻōlelo ʻia: 0.12–0.24%. No ka sima ikaika kiʻekiʻe, ka sima me ka pauka lehu lele/slag nui, a i ʻole ka sima me nā koi kūikawā, hiki ke hoʻonui ʻia ka nui i ʻoi aku ma mua o 0.3% (akā ʻaʻole ma mua o 0.5%). Hōʻike nā hoʻokolohua ma ka nui o 0.5%, ʻaʻole e nalowale ka pili ʻana o ka sima a i ʻole ka hoʻokaʻawale ʻana o ka aggregate-paste, e hoʻomau ka piʻi ʻana o ka nui o ka hōʻemi ʻana o ka wai, akā e piʻi ana ka nui o ka ea, e lohi ana ka hoʻonohonoho ʻana, a e emi iki ana ka ikaika.
