Zotsatira za mchenga wopangidwa ndi makina komanso kusinthasintha kosakanikirana pamtundu wa konkire

Ukadaulo wa rock ndi kupanga kwa mchenga wopangidwa ndi makina m'magawo osiyanasiyana ndi osiyana kwambiri. Mlingo wa mayamwidwe amadzi a mchenga wopangidwa ndi makina umakhudza kuwonongeka kwa konkire kumlingo wina, ndipo kuchuluka kwa matope mumchenga wopangidwa ndi makina sikudzangokhudza mphamvu ya konkire, makamaka kubwerera kolimba. Elastic mphamvu ndi durability, chifukwa chodabwitsa cha ufa pa konkire pamwamba, komanso zoipa kulamulira mtengo wa kusakaniza chomera. Fineness modulus ya mchenga wopangidwa pano ndi 3.5-3.8, kapena 4.0, ndipo gradation yake ndi yosweka kwambiri komanso yosamveka. Gawo lapakati pa 1.18 ndi 0.03mm ndi laling'ono kwambiri, lomwe ndizovuta kupopera konkire.

1. Pakupanga mchenga wopangidwa ndi makina, zomwe zili mu ufa wa miyala ziyenera kuyang'aniridwa mosamalitsa kuti zikhale pafupifupi 6%, ndipo matope ayenera kukhala mkati mwa 3%. Zomwe zili mu ufa wamwala ndizowonjezera zabwino za mchenga wosweka wopangidwa ndi makina.

2. Pokonzekera konkire, yesetsani kusunga ufa wina wa miyala kuti mukwaniritse gradation yoyenera, makamaka kulamulira kuchuluka kwa pamwamba pa 2.36mm.

3. Pamaziko owonetsetsa mphamvu ya konkire, mlingo wa mchenga uyenera kuyendetsedwa bwino, gawo la miyala yayikulu ndi yaying'ono liyenera kukhala loyenera, ndipo kuchuluka kwa miyala yaing'ono kungawonjezedwe moyenera.

4. Mchenga wa makina ochapira makamaka umagwiritsa ntchito flocculant kuti uwombe ndi kuchotsa matope, ndipo gawo lalikulu la flocculant lidzatsalira mumchenga womalizidwa. The mkulu maselo kulemera flocculant ali ndi chikoka kwambiri makamaka pa madzi kuchepetsa wothandizila, ndi fluidity ndi kugwa imfa ya konkire ndi makamaka makamaka pamene kuchuluka kwa admixture kawiri.

Mphamvu ya Admixture ndi Admixture Adaptability pa Konkrete Quality

Power plant ntchentche phulusa kale kusowa, ndi milled ntchentche phulusa amabadwa. Mabizinesi okhala ndi chikumbumtima chabwino amawonjezera gawo lina la phulusa laiwisi. Mabizinesi amtima wakuda onse ndi ufa wamwala. Chachikulu, ntchitoyo ndi 50% mpaka 60%. Kuchuluka kwa ufa wa laimu wosakanikirana mu phulusa la ntchentche sikudzangokhudza kutaya pa kuyaka kwa phulusa la ntchentche komanso kukhudza ntchito yake.

1. Limbikitsani kuwunika kwa phulusa la ntchentche, mvetsetsani kusintha kwa kutayika kwake pakuyatsa, ndipo tcherani khutu ku chiŵerengero cha madzi.

2. Mulingo wina wa klinker ukhoza kuwonjezeredwa ku phulusa la ntchentche zogaya kuti muwonjezere ntchito.

3. Ndizoletsedwa kugwiritsa ntchito malasha gangue kapena shale ndi zinthu zina zokhala ndi madzi okwera kwambiri pogaya phulusa la ntchentche.

4. Kuchuluka kwa zinthu zokhala ndi zinthu zochepetsera madzi kungathe kuwonjezeredwa moyenerera ku phulusa la ntchentche, zomwe zimakhala ndi zotsatira zina pa kulamulira chiŵerengero cha madzi.
