1.Chiyambi cha mankhwala

Polycarboxylate superplasticizer yamphamvu kwambiri ndi chisa chopangidwa ndi polycarboxylate superplasticizer chomwe chimapangidwa ndi carboxylic acid ndi ester macromonomers.Mphamvu yoyambirira ya konkire yosakanikirana ndi mankhwalawa imatha kusintha kwambiri, ndipo mphamvu yapambuyo pake simachepa.Ndi oyenera precast konkire ndi osiyanasiyana mkulu-mphamvu ndi mkulu-ntchito konkire, amene angafupikitse nthawi demoulding ndi kusintha nkhungu chiwongola dzanja dzuwa.Chogulitsachi chili ndi izi:

(1) Mlingo wapamwamba wochepetsera madzi, kubalalitsidwa kwabwino komanso kubalalitsidwa posungira zotsatira pa simenti;
(2) Mphamvu zoyambirira zowonjezera mphamvu za konkire ndizodziwikiratu, ndipo mphamvu yapambuyo pake ilibe kuchepa;
(3) mpweya okhutira ndi otsika, amene amachepetsa zotsatira zoipa thovu mpweya mu konkire pa dongosolo mkati, ndipo akhoza kusintha maonekedwe a konkire nthawi yomweyo;
(4) Kusinthika kwabwino kwa magiredi osiyanasiyana ndi opanga osiyanasiyana simenti, komanso kuyanjana kwabwino ndi ma admixtures.

2. Zogulitsa Zamalonda

(1) Kuchepetsa kwambiri madzi: Mankhwalawa ali ndi mlingo wa 0.15-0.3% (potengera zolimba) komanso kuchepetsa madzi a 18-40%, omwe amatha kukwaniritsa zosowa za simenti yamadzi otsika kwambiri. chiŵerengero ndi mkulu fluidity konkire.Sungani 10 mpaka 20% ya simenti.
(2) Low slump imfa: Izi mankhwala limayambitsa yaitali mbali unyolo wa macromolecules mu kaphatikizidwe ndondomeko, pa dzanja limodzi, izo linalake ndipo tikulephera hydration, ndipo Komano amapereka wosabala chotchinga, amene akhoza kusunga slurry pulasitiki kwa nthawi yaitali, ndi ali ndi ntchito yabwino.kuchepa kwamphamvu.
(3) Kuchita bwino kwambiri: Konkire yokonzedwa ndi mankhwalawa imakhala yogwira ntchito bwino, palibe tsankho, palibe delamination, mgwirizano wabwino, ndipo ndi yoyenera kuyenda ndi kupopera mtunda wautali.
(4) High durability: Izi mankhwala polymerized ndi ufulu ankafuna kusintha amadzimadzi njira, ndi pang'ono kolorayidi ion zili, pang'ono chabe alkali ntchito neutralization, zili zamchere ndi otsika kwambiri, ndi alkali zili ndi chloride ion zili ndi khola, ndi klorini otsika ndi otsika alkali akhoza kukhala lalikulu.Kupititsa patsogolo kulimba kwa konkriti.
(5) Low shrinkage ndi anti-cracking: Mankhwalawa amatha kuchepetsa kutentha kwa hydration, kuchedwetsa nsonga ya exothermic, ndipo ndi yoyenera kwa konkire yaikulu, yomwe imatha kuchepetsa kuphulika kwa konkire chifukwa cha kusiyana kwa kutentha kwa hydration.
(6) Kuteteza chilengedwe chobiriwira: Izi zimapangidwa ndi polymerized ndi njira yamadzimadzi yaulere.Zopangirazi zilibe formaldehyde ndi zoipitsa zina.Palibe kutayira kwa zimbudzi ndi zinyalala panthawi ya kaphatikizidwe, ndipo chilengedwe chimakhala chotsika kwambiri.Ndi mtundu watsopano wa zomangira zobiriwira komanso zachilengedwe.
monga mtundu umodzi wa zosakaniza zochepetsera madzi bwino kwambiri,
