Compound technical analysis:

1. Kuonjezera mavuto ndi mowa wa mayi

Polycarboxylate yochepetsera madzi ndi mtundu watsopano wazomwe zimagwira ntchito kwambiri zochepetsera madzi. Poyerekeza ndi mankhwala achikhalidwe ochepetsera madzi, imakhala ndi dispersibility yamphamvu mu konkriti ndipo imakhala ndi kuchuluka kwamadzi ochepetsa. Kuphatikizika kwa chakumwa cha mayi wochepetsera madzi kumatha kutheka pamlingo wina. Kusintha kachulukidwe mankhwala maselo mbali unyolo, zambiri kulankhula, kuonjezera pakati pa mowa mowa akhoza kupeza zotsatira zabwino. Mowa wa mayi wosakwatiwa ukhoza kuphatikizidwa ndi zakumwa zoledzeretsa za amayi ambiri kuti akwaniritse ntchito zake, koma ziyenera kudziwidwa kuti zakumwa zoledzeretsa zamtundu wapamwamba komanso zogwira mtima kwambiri ziyenera kusankhidwa. Nthawi yomweyo, asidi a polycarboxylic sangathe kuphatikizidwa ndi zinthu zina zochepetsera madzi, monga mndandanda wa naphthalene ndi aminoxantholate.

2. Kuphatikizana ndi zinthu zina zogwirira ntchito

Muzomangamanga zenizeni, kuti athetse mavuto omwe amakumana nawo pomanga polojekitiyi, m'pofunika kukonza ntchito ya konkire. Ngati mowa wa mayi wokhawokha sangathe kukwaniritsa zofunikira, pamenepa, zipangizo zina zing'onozing'ono, kuphatikizapo thickeners, ndi zina zotero, ziyenera kuwonjezeredwa kuti ziwonjezeke ntchito ya konkire. . Retarder ikhoza kuwonjezeredwa ku konkire, yomwe ndi chinthu chaching'ono chomwe chimasintha chochepetsera madzi kuti chigwirizane ndi nthawi yokhazikika pansi pa kutentha kosiyana. Kuonjezera gawo la retarder kumachepetsa kuchuluka kwa konkriti. Pa nthawi imodzimodziyo, powonjezera chotsitsacho, ziyenera kuzindikiridwa kuti retarder palokha imakhala ndi mphamvu yochepetsera madzi, ndipo chinthu ichi chiyenera kuganiziridwa panthawi yophatikizana ndi wothandizira kuchepetsa madzi. Vuto la kutuluka kwa madzi mu konkire ndilofalanso m'mapulojekiti. Pachifukwa ichi, zowonjezera ndi zopangira mpweya zingagwiritsidwe ntchito kukonza vutoli, koma mpweya wa konkire uyenera kuyendetsedwa bwino, apo ayi mphamvu ya konkire idzachepetsedwa.
