Zoletsa kuwuma zowonjezera auzidwa: specifications luso

Zoletsa kuwuma zowonjezera auzidwa - ndi osakaniza youma kapena njira ya mankhwala, amene yodziwika ndi mwachilungamo yaitali moyo alumali. Cholinga cha zowonjezerazo ndi kupereka concreting ntchito m'nyengo yozizira.

Latsopano Integrated zoletsa kuwuma zina, kupatula kusintha njira anapereka simenti matope mphamvu zonse angapo katundu rheological. Chifukwa, kutsitsa kutentha kuchepa kolowera nthawi, mofulumira ndondomeko kuumitsa mwala simenti ndi mphamvu yake ukuwonjezeka pa kalasi 2 kalasi.

Gawo

zina zoletsa kuwuma mu njira (simenti) pa maziko a mankhwala akhoza kugawidwa mu magulu atatu akulu akulu:

• Zoletsa kuwuma.
• Sulfates.
• Zima zoletsa kuwuma zina boosters.

Tiyeni tione iwo mwatsatanetsatane.

zoletsa kuwuma

Izi zowonjezera zoletsa kuwuma auzidwa amachepetsa yozizira koopsa mfundo ya madzi, Iyamba kapena ofooka kumabwezera mmbuyo kolowera njira. Mu zoletsa kuwuma izi sizisintha liwiro mapangidwe nyumba.

sulfates

Iron sulphate, zotayidwa kapena zitsulo zina ndi zoletsa kuwuma chigawo, Kuwonjezera umene amapereka mapangidwe kwambiri mofulumira njira yaying'ono. mankhwalawo komanso malo anakhudzidwa ndi kutentha yogwira, amene anatsagana ndi anachita ndi hydration katundu konkire. Inu simungakhoze ntchito zowonjezera kuchepetsa mpaka madzi kuundana, monga kwathunthu kugwirizana ndi mankhwala bwino sungunuka.

Zima zoletsa kuwuma zina boosters

Zoletsa kuwuma zina mwa njira (simenti) wa mtundu uwu zimathandiza kuti mlingo wa solubility zigawo zikuluzikulu silicate simenti anapanga chifukwa iwiri kapena salt m'munsi ndi mankhwala hydration. Ambiri a iwo nthawi yomweyo kuchepetsa mpaka madzi kuundana.

mitundu

• Potashi - amphamvu zoletsa kuwuma zowonjezera auzidwa, Iyamba ndondomeko oipa. Pofuna kupewa mphamvu kuchepetsa potashi analimbikitsa kuphatikiza ndi phala yisiti sulfite, ndi sodium tetraborate kapena retarders ena. Ndende mu osakaniza sayenera upambana 30%.
• Sodium nitrite - moto woopsawo poizoni zoletsa kuwuma zowonjezera mu konkire. Pankhani ya ntchito limodzi ndi lignosulphonates akhoza kupanga mpweya chakupha. Mlingo ayenera kukhala wotsimikiza empirically ndi uthunthu 0,1-0,42 L / kg wa simenti slurry pa yozungulira kutentha kwa 0 kuti -25 ºC.
• Sodium formate ndi zoletsa kuwuma accelerator. Ntchito kulera plasticizing, madzi kuchepetsa katundu. Akulimbikitsidwa kugwiritsa ntchito molumikizana ndi naphthalene lignosulfonate. Izi zowonjezera zoletsa kuwuma mu konkire ndi simenti misa otaya ali avareji 2-6%.

Kukonza ntchito simenti m'nyengo yozizira, kuwonjezera pa pamwamba, munthu akhoza kusankha pa maziko a zoletsa kuwuma zowonjezera ndi sodium formate mowa, urea, madzi amoniya kapena kashiamu mankhwala enaake.

ubwino

• Plasticizing ndi wosasunthika okonzeka mix simenti.
• Iwo zimathandiza kuti ntchito simenti m'nyengo yozizira.
• Kumawonjezera moyo wautali osakaniza pa ntchito yomanga.
• Bwino chomaliza chisanu njira.
• Kumachepetsa m'mbuyo mapindikidwe.
• Kumachepetsa kulekana madzi ndi ndondomeko delamination.
• Amachepetsa mtengo wa unsembe.
• Kumatha dzimbiri kwa ikuthandizira mauna mkati.

Ntchito zina zoletsa kuwuma kwa konkire Nthawi zambiri zimabweretsa ndalama kwambiri.

zolakwa

• Ena zigawo zikuluzikulu zowonjezera amaonedwa poizoni.
• Pofuna molondola kuonetsetsa mphamvu makhalidwe a ukuwonjezeka mowa simenti.
• Nthawi zina imagwera mphamvu malamulo a mtundu konkire.

ntchito Mfundo Zina

Zoletsa kuwuma zowonjezera umayamba mu konkire Kusakaniza pamodzi ndi madzi, makamaka ndi wachitatu otsiriza a madzi. Ndi osafunika kubaya wothandizila mu osakaniza youma. Pambuyo zowonjezera wakhala anadzetsa njira, m'pofunika kudikira nthawi zina kuonetsetsa kugawa ake yunifolomu.

Nkofunika kutsatira malangizo ntchito msonkhano mu nthawi yozizira:

• Pa kunagwa chipale chofewa ndi muyenera kuchita m'misasa wapadera.
• Analimbikitsa kutentha yankho pa kubwereketsa wa chosakanizira cha: kuchokera +15 ºC kuti +25 ºC.
• Kukonzekera osakaniza ndi zofunika kutenga madzi mkangano.
• Kutentha kwa aggregates kuchitidwa mwachindunji pamaso ntchito.

Kuti tipeze yankho ndi zofunika makhalidwe mphamvu, Ndi bwino kutsatira mfundo kusamalira konkire m'nyengo yozizira, malinga ndi SNIP 03/03/01. Ndi zofunika kuchita zochita kukwaniritsa mphamvu ya osachepera 20% ya kapangidwe ndi nthawi yozizira njira yothetsera kutentha pa zimene mlingo mawerengedwe chitachitidwa.

Zoletsa kuwuma zowonjezera auzidwa: zofunika

mlingo

Mlingo zoletsa kuwuma zowonjezera ayenera anasankha lililonse nkhani zosiyanasiyana ndi kumuyesa zinthu mafakitale ndi zasayansi. Izo zimatengera zotsatirazi:

• Terms of kusamalira konkire.
• Kutentha kwa yankho pa kubwereketsa wa chosakanizira konkire.
• Yozungulira kutentha.
• Real ndi mankhwala-mineralogical zikuchokera njira ndi chitukuko mphamvu.
• Kuwasindikiza simenti mphamvu.

Pakuti yosungirako yaitali, kapena ntchito zina buku lalikulu tikulimbikitsidwa kuti nthawi homogenizing njira ndi oyambitsa kapena sparging ndi wothinikizidwa mpweya. Mlingo ayenera kuchitidwa ndi lolondola ± 2%.

Zoletsa kuwuma zowonjezera auzidwa ndi manja awo

Dziwani kuti njira yochezera ndi kugula okonzeka zopangidwa admixtures konkire yothetsera mu shopu aliyense apadera. Iwo sali ngati mtengo, ndi otsika mowa ndipo motero kupereka mu nthawi yozizira, kuwongolera kwambiri pa katundu wa njira ndi zotsatira kochepa negative.

Pamene yaing'ono ntchito kutsogolo ndi kutentha mpweya wa osachepera 10 ºC, njira idzakhala mulingo woyenera.

Komabe, zimachitika kuti zoletsa kuwuma zowonjezera auzidwa, zopangidwa ndi manja ake - ichi ndi njira yokha. Nkhani iyi, muyenera kulabadira mankhwala enaake a (mchere). Mankhwala enaake salt akhoza kwambiri kuchepetsa yozizira koopsa mfundo za njira, kuchepetsa kolowera nthawi ndi kuchepetsa kumwa simenti. Koma ngati zoletsa kuwuma zowonjezera mu konkire (ndemanga akatswiri akutitsimikizira izi) angagwiritsidwe ntchito nyumba unreinforced yekha.

kusamala

Pamene tikugwira ntchito ndi mankhwala a mtundu uwu akulimbikitsidwa kugwiritsa ntchito magolovesi zozitetezera.

Pambuyo kukhudzana ndi khungu poyera n'kofunika kutsuka ndi sopo ndi madzi. Musalole chilichonse zowonjezera zoletsa kuwuma mu diso. Zikatero m'pofunika yomweyo muzimutsuka zikutanthauza buku waukulu wa madzi ndi pitani kuchipatala.

Ntchito ndi zowonjezera malinga ndi malamulo wamba, ndi kutiletsa zimatulutsa mu bere, madzi pamwamba ndi dothi.
