Kodi Mumadziwa Zotani Zokhudza Wochepetsera Madzi?

Tsiku Lotumiza: 9, Sep, 2024

Madzi ochepetsera ndi kuphatikiza konkriti komwe kumatha kuchepetsa kuchuluka kwa madzi osakanikirana ndikusunga kutsika kwa konkire. Ambiri aiwo ndi anionic surfactants. Pambuyo kuwonjezeredwa kusakaniza kwa konkire, zimakhala ndi zotsatira zowonongeka pa tinthu tating'ono ta simenti, zomwe zingathe kupititsa patsogolo ntchito yake, kuchepetsa kugwiritsira ntchito madzi a unit, ndikuwongolera kusakaniza kwa konkire; kapena kuchepetsa kugwiritsa ntchito simenti ndi kusunga simenti.

Malinga ndi mawonekedwe:
Amagawidwa m'madzi opangira madzi ndi ufa. Madzi olimba omwe ali ndi madzi nthawi zambiri amakhala 10%, 20%, 40% (omwe amadziwikanso kuti chakumwa cha mayi), 50%, ndipo ufa wokhazikika ndi 98%.

Malinga ndi kuthekera kochepetsera madzi ndikuwonjezera mphamvu:
Amagawidwa kukhala ochepetsera madzi wamba (omwe amadziwikanso kuti plasticizer, omwe amatsitsa madzi osachepera 8%, omwe amaimiridwa ndi lignin sulfonates), otsitsa madzi othamanga kwambiri (omwe amadziwikanso kuti superplasticizer, omwe amatsitsa madzi osachepera. kuposa 14%, kuphatikizapo mndandanda wa naphthalene, mndandanda wa melamine, mndandanda wa aminosulfonate, mndandanda wa aliphatic, etc.) kuposa 25%, woimiridwa ndi polycarboxylic acid mndandanda madzi reducer), ndipo lagawidwa mu mtundu oyambirira mphamvu, mtundu muyezo ndi pang'onopang'ono khazikitsa mtundu motero.

Malinga ndi zolembedwa:
Lignin sulfonates, polycyclic onunkhira mchere, madzi sungunuka utomoni sulfonates, naphthalene zochokera mkulu-mwachangu madzi ochepetsera, aliphatic mkulu-mwachangu madzi reducer, amino mkulu-mwachangu zochepetsera madzi, polycarboxylate mkulu-ntchito zochepetsera madzi, etc.

Malinga ndi chemical composition:
Lignin sulfonate water reducers, naphthalene-based high-efficiency reducers, melamine-based high-efficiency reducers, aminosulfonate-based high-efficiency reducers, fatty acid-based high-efficiency water reducers, polycarboxylate-based high-efficiency water reducers. .

Ntchito yochepetsera madzi:
1.Popanda kusintha chiŵerengero cha zipangizo zosiyanasiyana (kupatula simenti) ndi mphamvu ya konkire, kuchuluka kwa simenti kungachepetse.
2.Popanda kusintha chiŵerengero cha zipangizo zosiyanasiyana (kupatula madzi) ndi kugwa kwa konkire, kuchepetsa kuchuluka kwa madzi kumatha kusintha kwambiri mphamvu ya konkire.
3.Popanda kusintha chiŵerengero cha zipangizo zosiyanasiyana zopangira, rheology ndi pulasitiki ya konkire imatha kusintha kwambiri, kotero kuti zomangamanga za konkire zikhoza kuchitidwa ndi mphamvu yokoka, kupopera, popanda kugwedezeka, ndi zina zotero, kuwonjezera liwiro la zomangamanga ndi kuchepetsa mphamvu yomangamanga. .
4.Kuwonjezera mphamvu yochepetsera madzi ku konkire kungapangitse moyo wa konkire ndi kuwirikiza kawiri, ndiko kuti, kuwonjezera moyo wautumiki wa nyumbayo mopitirira kawiri.
5.Kuchepetsa kuchepa kwa kulimbitsa konkire ndikuletsa ming'alu ya zigawo za konkire; onjezerani kukana kwa chisanu, zomwe zimathandizira kumanga kwachisanu.
