(一) Malumikizidwe Okhazikika
Chochitika:Ming'alu ingapo yaifupi, yowongoka, yotakata komanso yosazama idzawoneka mu konkire yotsanuliridwa isanayambe komanso itatha kukhazikitsidwa koyamba.
Chifukwa:Pambuyo powonjezera madzi ochepetsera madzi, konkire imakhala yowoneka bwino, sichimatuluka magazi ndipo si yosavuta kumira, ndipo imawoneka pamwamba pazitsulo zazitsulo.
Yankho: Ikani kupanikizika kwa ming'alu isanayambe komanso itatha kukhazikitsidwa koyambirira kwa konkire mpaka ming'alu itatha.
(二) Zitini Zomata
Chochitika:Mbali ya matope a simenti imamatira ku khoma la mbiya yosakaniza, kuchititsa konkire yotuluka m'makina kukhala yosagwirizana komanso phulusa lochepa.
Chifukwa:Konkire ndi yomata, yomwe nthawi zambiri imachitika mukawonjezera kuchedwetsa kusakaniza kochepetsera madzi, kapena muzosakaniza za ng'oma zokhala ndi chiŵerengero chapafupi cha shaft m'mimba mwake.
Yankho:1. Samalani kuchotsa konkire yotsalira mu nthawi. 2. Choyamba onjezerani zophatikiza ndi gawo la madzi ndikusakaniza, kenaka yikani simenti, madzi otsala ndi madzi ochepetsera ndikusakaniza. 3. Gwiritsani ntchito chosakaniza chokhala ndi chiŵerengero chachikulu cha shaft m'mimba mwake kapena chosakaniza chokakamiza
(三) Coagulation zabodza
Chochitika:Konkire imataya msanga madzi atasiya makina ndipo sangathe ngakhale kutsanuliridwa.
Chifukwa:1. Kusakwanira kwa calcium sulfate ndi gypsum zomwe zili mu simenti zimapangitsa kuti calcium aluminate ikhale ndi madzi mofulumira kwambiri; 2. Njira yochepetsera madzi imakhala yosasinthika ku mtundu uwu wa simenti; 3. Pamene zinthu za triethanolamine zimaposa 0.05-0.1%, malo oyambirira adzakhala ofulumira. Koma osati chomaliza.
Yankho:1. Sinthani mtundu wa simenti kapena nambala ya batch. 2. Sinthani mtundu wa wothandizira kuchepetsa madzi ngati kuli kofunikira, koma nthawi zambiri sikofunikira. 3. Kuchepetsa kuchepetsa madzi ndi theka. 4. Chepetsani kutentha kusakaniza. 5. Gwiritsani ntchito Na2SO4 kuchedwetsa zomwe zili pa 0.5-2%.
(四) Palibe Coagulation
Zodabwitsa: 1. Pambuyo powonjezera wothandizira kuchepetsa madzi, konkire sinalimbitse kwa nthawi yaitali, ngakhale usana ndi usiku; 2. Pamwamba pamakhala matope ndipo amasanduka chikasu chofiirira.
Chifukwa:1. Mlingo wa wothandizira kuchepetsa madzi ndi waukulu kwambiri, womwe ukhoza kupitirira nthawi 3-4 mlingo wovomerezeka; 2. Kugwiritsa ntchito kwambiri retarder.
Yankho:1. Musapitirire mlingo woyenera 2-3 nthawi. Ngakhale mphamvu imachepetsedwa pang'ono, mphamvu ya 28d idzachepetsedwa pang'ono ndipo mphamvu ya nthawi yayitali idzachepetsedwa ngakhale pang'ono. 2. Mukamaliza kukhazikitsa, onjezerani kutentha kwa machiritso moyenera ndikulimbitsa kuthirira ndi kuchiritsa. 3. Chotsani gawo lopangidwa ndikutsanuliranso.
(五) Kutsika Kwambiri
Chochitika:1. Mphamvu ndizochepa kwambiri kuposa zotsatira za mayeso a nthawi yomweyo; 2. Ngakhale konkire yalimba, mphamvu zake ndizochepa kwambiri.
Chifukwa:1. Kuchuluka kwa mpweya wochepetsera madzi kumapangitsa kuti mpweya ukhale wochuluka kwambiri. 2. Kugwedezeka kosakwanira mutatha kuwonjezera mpweya wochepetsera madzi. 3. Madzi samachepetsedwa kapena kuchuluka kwa simenti yamadzi kumawonjezeka m'malo mwake. 4. Kuchuluka kwa triethanolamine yowonjezeredwa ndi yaikulu kwambiri. 5. Ubwino wa wothandizira kuchepetsa madzi sagwirizana ndi zofunikira, monga momwe zinthu zogwirira ntchito zogwirira ntchito ndizochepa kwambiri.
Yankho:1. Gwiritsani ntchito njira zina zolimbikitsira kapena kuthiranso. 2. Limbitsani kugwedezeka mutatha kuthira. 3. Chitanipo kanthu motsutsana ndi zifukwa zomwe tafotokozazi. 4. Dziwani gulu ili la zosakaniza zochepetsera madzi.
(六) Kutayika kwa Slump Ndikofulumira Kwambirit
Chochitika:Konkire imataya ntchito mwachangu kwambiri. Pakatha mphindi 2-3 mutachoka mu thanki, kugwa kumachepa ndi 1-2cm, ndipo pamakhala chodziwikiratu chomira pansi. Chodabwitsa ichi chimakonda kuchitika konkriti ndi kugwa kwakukulu.
Zifukwa:1. Njira yochepetsera madzi imakhala yosasinthika ku simenti yogwiritsidwa ntchito. 2. Mapiritsi a mpweya omwe amalowetsedwa mu konkire amapitirirabe ndipo madzi amatuluka, makamaka pogwiritsa ntchito mpweya wochepetsera madzi. 3. Kutentha kosanganikirana konkire kapena kutentha kozungulira ndikokwera; 4. Kutsika konkriti ndi kwakukulu.
Yankho:1. Chitanipo kanthu motsutsana ndi zomwe zayambitsa. 2. Pezani njira yosakaniza pambuyo posakaniza. Wothandizira kuchepetsa madzi ayenera kuwonjezeredwa mutatha kusakaniza konkire kwa mphindi 1-3, kapena ngakhale asanathire, ndikuyambitsanso. 3. Samalani kuti musawonjezere madzi.
