1.Mlingo wa polycarboxylate superplasticizer wochepetsera madzi ndi waukulu kwambiri, ndipo pali thovu zambiri pamwamba pa kapangidwe ka konkire.
Kuchokera pakuwona kwamphamvu komanso kukhazikika, ndizopindulitsa kuonjezera moyenera zinthu zopangira mpweya. Mankhwala ambiri ochepetsa madzi a polycarboxylate ali ndi zinthu zambiri zopatsa mpweya. Zosakaniza zochepetsera madzi zochokera ku polycarboxylic acid zilinso ndi machulukitsidwe monga zosakaniza zochepetsera madzi za naphthalene. Kwa mitundu yosiyanasiyana ya simenti ndi milingo yosiyana ya simenti, machulukitsidwe a ma admixture awa mu konkire ndi osiyana. Ngati kuchuluka kwa admixture pafupi ndi machulukitsidwe mfundo yake, ndi fluidity wa osakaniza konkire akhoza bwino ndi kusintha kuchuluka kwa slurry mu konkire kapena kugwiritsa ntchito njira zina.
Zodabwitsa: Malo ena osakaniza akhala akugwiritsa ntchito polycarboxylic acid yochepetsera madzi pokonza konkire kwa nthawi ndithu. Mwadzidzidzi tsiku lina, malo omangawo adanena kuti atachotsa mawonekedwe a khoma lakumeta ubweya, anapeza kuti panali thovu zambiri pamwamba pa khomalo ndipo maonekedwe ake anali oipa kwambiri.
Chifukwa: Patsiku lothira konkire, malo omangawo adanena nthawi zambiri kuti kugwa kunali kochepa ndipo madziwo anali osauka. Ogwira ntchito mu labotale ya siteshoni yosakaniza konkire anawonjezera kuchuluka kwa admixtures. Malo omangawo ankagwiritsa ntchito zitsulo zazikulu zooneka ngati zitsulo, ndipo zinthu zambiri zinkawonjezedwa nthawi imodzi pothira, zomwe zinachititsa kuti pakhale kugwedezeka kosiyana.
Katetezedwe: Limbikitsani kulankhulana ndi malo omangapo, ndipo limbikitsani kuti kutalika kwa chakudya ndi njira yogwedezeka zigwiritsidwe ntchito motsatira ndondomeko. Limbikitsani madzi a konkire kusakaniza mwa kusintha kuchuluka kwa slurry mu konkire kapena kugwiritsa ntchito njira zina.
2.Polycarboxylate yochepetsera madzi ndi yosakanikirana kwambiri ndipo nthawi yokhazikika imatalika.
Chochitika:Kutsika kwa konkire ndi kwakukulu, ndipo zimatenga maola 24 kuti konkire ikhazikike. Pamalo omanga, maola 15 pambuyo pa mtengo womangakonkire idatsanuliridwa, idanenedwa ku malo osakaniza kuti gawo la konkire silinalimbane. Malo osanganikirana adatumiza mainjiniya kuti akafufuze, ndipo pambuyo pa chithandizo cha kutentha, kulimbitsa komaliza kunatenga maola 24.
Chifukwa:Kuchuluka kwa zaka zochepetsera madzint ndi yayikulu, ndipo kutentha kozungulira kumakhala kochepa usiku, kotero kuti konkire ya hydration imachedwa. Otsitsa ntchito pamalo omangawo amawonjezera madzi mobisa ku konkire, yomwe imadya madzi ambiri.
Kupewa:Kuchuluka kwa kuphatikiza shchikhale choyenera ndipo muyeso uyenera kukhala wolondola. Timakukumbutsani kuti muzisamala za kusungunula ndi kukonza pamene kutentha kwa malo omangako kumakhala kochepa, ndipo ma polycarboxylic acid admixtures amakhudzidwa ndi kumwa madzi, choncho musawonjezere madzi mwakufuna kwanu.
