A. Madzi ochepetsa madzi

Chimodzi mwazomwe zimagwiritsa ntchito madzi kuchepetsa mankhwala ndikuchepetsa kumwa kwa konkriti ndikuwongolera madzi konkriti mongoteteza kukula kwa madzi osasinthika, kuti akwaniritse zomangamanga. Madzi ambiri amachepetsa ma addictures ali ndi mlingo wokwiya. Ngati kuchuluka kwa kuchuluka kwapitilira, madzi ochepetsa madzi sakula, ndipo magazi ndi tsankho zidzachitika. Mlingo womwe wakhudzidwa ukugwirizana ndi zowerengera zonse ndi kuphatikiza konkriti.

 

1. Naphthalene superplastiter

Naphthalene superplastiterItha kugawidwa kukhala zinthu zapamwamba kwambiri (NA2SO4 Zolemba <3%), zinthu zapakatikati pa 3% ~ 10%) ndi zinthu zotsika mtengo> malinga ndi zomwe zili Na2So4. Mlingo wambiri wa Naphthalene mndandanda wamadzi wotsika: ufa ndi 0,5 ~ 1.0% ya simenti; Zomwe zili zolimba za yankho nthawi zambiri zimakhala 38% ~ 40%, 2% ~ 2,5% yazosangalatsa, ndipo madzi ochepetsa madzi ndi 18% ~ 25% ~ 25%. Natero Nafinyaiti mndandanda wamadzi ochepera satuluka magazi, ndipo sawakhudza nthawi yokhazikika. Itha kuphatikizidwa ndi sodium gluconate, shuga, hydroxcarboxylicylicylicyliccylic, citric acid ndi mankhwala oyenera a mpweya, kuwonongeka koyenera kumatha kulamuliridwa bwino. Zovuta za nthawi yotsika ndi naphthalene misiri amadzi ndikuti zomwe zili mu sodium sulfate ndi yayikulu. Matenthedwe otsika pomwe 15 ℃, sodium sulfate brystallization umachitika.

Polycaxomyylic acidKuchepetsa kwamadzi kumawonedwa ngati m'badwo watsopano wamadzi ocheperako, ndipo anthu nthawi zonse amayembekeza kuti zingakhale zotetezeka, zotheka kusintha kwambiri kuposa zikhalidwe zachikhalidwe mu ntchito. Ubwino wa ma polycaxtlic acid acid Zolemba, komanso zochepa kwambiri za alkali.

Komabe, pochitapo kanthu,Polycaxomyylic acidKutsika kwamadzi kumakumananso ndi zovuta zina, monga: 1. Madzi ochepetsa mphamvu zimatengera zida zophatikizika ndikusakaniza sing'anga ndi miyala ndi michere ya mchere; 2. Madzi ochepetsera ndi opukuta amadalira kwambiri pamlingo wamadzi ochepetsa mphamvu, ndipo nkovuta kuti muzitha kukhala ndi pang'ono; 3. Kugwiritsa ntchito konkriti kwa ndende kwambiri kapena konkriti yayikulu kwambiri kumakhala ndi kabwino kambiri, komwe kumakonda kugwiritsa ntchito madzi, komanso kusinthasintha kwamadzi komwe kumayambitsa kusintha kwakukulu; 4. Pali vuto logwirizana ndi mitundu ina ya madzi ochepetsa madzi ndi kuvomerezeka kwina, kapenanso kulibe zotsatirapo zopambana; 5. Nthawi zina konkriti imakhala ndi madzi ambiri m'madzi ambiri, poizoni kwambiri, ndi thovu lalikulu komanso ambiri; 6. Nthawi zina kusintha kutentha kumakhudza zotsatira zaPolycaxomyylic acidkutsika kwamadzi.

Zinthu zomwe zikugwirizana ndi simenti ndiPolycaxomyylic acidKuchepetsa Madzi: 1. Chiwerengero cha C3a / C4af ndi C3a / C2s chikuwonjezeka, chophatikizika chimachepa, C3A chikuwonjezeka, ndipo kumwa madzi konkriti kumawonjezeka. Zomwe zili ndi zoposa 8%, kutayika konkire kumawonjezeka; 2. Kwambiri kwambiri kapena zazing'ono kwambiri za malkali zomwe zingasokoneze kugwirizana kwanu; 3. Ubwino wosauka wa sitejiyo sikosankha kungakhudzenso kugwirizana kwa awiriwa; 4. Mitundu yosiyanasiyana ya gypsum; 5. Mtengo wotentha kwambiri ungayambitse msanga pamene kutentha kumapitilira 80 ℃; 6. Cementi yatsopano ili ndi malo otetezeka komanso kuthekera kwamphamvu kuti muchepetse kutsika kwamadzi; 7.Kodi malo ena a simenti.
