Kodi madzi ndi otani?

Madzi amadzi (monga lumosulfonetes) ndi mtundu wa kuphatikizika komwe kamawonjezeredwa konkriti pakusakaniza. Madzi amadzi amatha kuchepetsa madzi ndi 12-30% popanda kunyalanyaza kugwiritsidwa ntchito kwa konkriti kapena mphamvu yamakina. Palinso mawu ena ochepetsa madzi, omwe ndi akuluakulu, ma pulasitiki kapena madzi okwera kwambiri (hrwr).

Mitundu yamadzi yochepetsera madzi

Pali mitundu ingapo yamadzi yochepetsera madzi. Makampani opanga amapereka mayina osiyanasiyana komanso magulu a ma armictiores awa monga odziwa madzi, mayamwidwe, Edidi Yogwira Ntchito, etc.

Nthawi zambiri, titha kugawanitsa madzi - mpumulo m'magulu atatu malinga ndi kapangidwe kake (monga mu tebulo 1):

Lignolfonites, hydroxcarboxylicylic acid, ndi hydroxynated ma polima.

Kodi Lignin amachokera kuti?

Lignin ndi zinthu zovuta zomwe zimayimira pafupifupi 20% ya nkhuni. Panjira yopanga zamkati zopanga mapepala kuchokera ku nkhuni, zakumwa zonyansa zimapangidwa ngati chinthu chokhala ndi zosakaniza zomwe zimakhala ndi ma celloul, zopangidwa ndi ma cagbohhhhydrates (shuga) ndi ma sulfurous acid kapena sulfi acild.

Kulowererapo mopanda malire, mpweya woponyerera ndi mphamvu zake zimatulutsa chikhazikitso chosiyanasiyana komanso kusiyanasiyana malinga ndi mitundu yambiri, njira yopendekera, ngakhale mtundu wa nkhuni zomwe zimagwiritsidwa ntchito ngati chakudya cha zamkati.

Lignosulfonites ngati madzi - mpumulo ku konkriti

Lignosulfonate SuperPlastic mlingo nthawi zambiri 0,25 peresenti, yomwe imatha kuchititsa kuti madzi achepetse madzi mpaka 12 peresenti pazinthu za simenti (0.20-0%). Monga momwe amagwiritsidwira ntchito muyezo woyenera, mphamvu ya konkriti inasintha ndi 15-20% poyerekeza ndi konkritiyo. Mphamvu zimakula ndi 20 mpaka 30 peresenti yambiri patatha masiku atatu, ndi 15-20 peresenti ya patatha masiku 7, ndipo pofanana ndi masiku 28.

Popanda kusintha madzi, konkriti imatha kuyenda momasuka, kuti ikhale yosavuta kugwira ntchito (mwachitsanzo, kuwonjezera kugwirira ntchito).

Pogwiritsa ntchito Tonne imodzi ya Lignosulfonate SuperPlastic ufa wa simenti, mutha kupulumutsa matani 30-40 a simenti pomwepo, kulimba, komanso konkriti.

Mu State State, konkriti yosakanikirana ndi wothandizikayo akhoza kuchedwetsa chinsinsi cha hydration pofika maola asanu, mphindi yomaliza yopitilira maola atatu, ndipo ndikukhazikitsa nthawi yopitilira maola atatu poyerekeza ndi konkriti. Izi ndizothandiza kwa chilimwe, katundu wa katundu, ndi konkriti.

Lignolfonate SuperPlastite yokhala ndi micro-zoikika zimatha kukulitsa magwiridwe antchito a konkriti malinga ndi Undeze-Thaw.
