Njira Zochita
Izi ndi bwino kuchepetsa madzi ndi steamed sodium sulfonate formaldehyde hypercondensed polima monga main component.The madzi tant ndi surfactant.Amadziwikanso kuti plasticizer, kusungunuka mu liquid.Imakonzedwanso monga oriented pa madzi pamwamba.Izi zimachepetsa mawonekedwe a mawonekedwe. Mphamvu.Chodabwitsachi chimatchedwa suractivity.Chinthu chokhala ndi surfacactivity choterechi chimatchedwa surfactant.Molekyulu ya surfactant imapangidwa ndi magawo awiri.Gawo ndi gulu la oleophilic losungunuka komanso losasungunuka m'madzi.Monga maziko onyansa.Mbali inayi ndi hydrophilic base yomwe imakhala yosavuta kuthirira komanso yosasungunuka mu mafuta.Pamene chikhalidwe cha hydrophilic cha gulu la hydrophilic chimakhala chachikulu kuposa gulu la hydrophilic.
Mankhwalawa akasiyanitsidwa m'madzi, amakongoletsedwa pamwamba pa tinthu ta simenti pamakonzedwe ake oyambira.Electrostatic magetsi amapangidwa.Chifukwa cha isoelectric gawo repulsion action.Disthe simenti particles.Kutulutsa madzi aulere atakulungidwa mu mawonekedwe oyambirira a polycoagulation.Kukwaniritsa cholinga cha kuchepetsa madzi.
Zizindikiro za Ntchito
1. Mankhwalawa ali ndi madzi abwino ochepetsera madzi, ali ndi ntchito yabwino yochepetsera madzi pansi pa kusakaniza kocheperako, makamaka pa konkire yapamwamba (pamwamba pa C50), kuchepetsa madzi ake kumatha kufika 38%.
2. Mankhwalawa ali ndi mphamvu zoyamba komanso zowonjezera, ndipo mphamvu zoyamba ndi zowonjezereka za konkire zimasakanikirana ndi mankhwalawa ndi apamwamba kuposa mitundu ina ya madzi ochepetsera.
3. Mankhwalawa ali ndi mpweya woyenerera, ndipo akhoza kusinthidwa malinga ndi zosowa zenizeni za polojekitiyi.
4. Mankhwalawa alibe chloride ion, sodium sulphate, yokhala ndi alkali yochepa, palibe dzimbiri ku mipiringidzo yachitsulo, kotero imatha kusintha kwambiri kukhazikika kwa konkire.
5. Mankhwalawa ali ndi kukhazikika kwa kukula, konkire yosakanizidwa mu mankhwalawa imatha kusintha bwino ntchito yake yowonongeka ndi kusokoneza, ndi kuchepetsa chiopsezo cha ming'alu.
6. Mankhwalawa ali ndi ntchito yabwino kwambiri yotetezera madzi, palibe kuchotsa madzi, palibe kusanthula kulekanitsa, kosavuta kukwaniritsa ntchito yomanga.
7. Izi zilibe formaldehyde, palibe kuchuluka kwa ammonia, ndizochepetsera madzi zachilengedwe.
Zizindikiro Zaukadaulo
l.Mankhwalawa amagawidwa kukhala ufa ndi madzi.Ufawu ndi bulauni-wachikasu. Madziwo ndi a bulauni-bulauni. Mankhwalawa alibe poizoni, onunkhira komanso osayaka.Palibe chiwonongeko pazitsulo zazitsulo.
2. Mankhwalawa ali ndi mphamvu yodziwikiratu yochepetsera madzi ndi kufalikira kwa madzi.Kuchepetsa kuchepetsa madzi kuli pakati pa 14 ndi 25% (kusinthidwa malinga ndi zofunikira za ogwiritsa ntchito ndi kusintha kwa simenti) .
3. Onjezani mankhwalawa ku condensate yonyowa, pansi pa mlingo womwewo wa simenti ndi malo omwewo akugwa, mphamvu yake yopondereza ya 1d ikhoza kusinthidwa ndi 40% mpaka 110%, 3d compressive mphamvu ndi 40% ~ 90%, 7d Hangzhou compression mphamvu ikhoza kukhala bwino ndi 30 ~ 80%, ndi 25% kwa 50% kwambiri kusintha thupi ndi makina ntchito 50% konkriti.Pangani psinjika ndi lopinda mphamvu konkire.The zotanuka modulus ndi durability bwino moyenerera.
4. Sinthani mosavuta konkire kusakaniza osakaniza ndi kuonjezera slump.Mu mlingo womwewo simenti ndi madzi kwa phulusa chiŵerengero.Kulowa mankhwala.Kugwa kwa konkire akhoza kwambiri anawonjezera.Kupititsa patsogolo chomasuka konkire.Kutalika kwa tsinde kumatha kupitirira 12 cm.
5. Pitirizani kutsika ndi mphamvu zomwezo.Lowani nawo mankhwalawa.Ikhoza kusunga oposa 12%.
6. Nthawi ya condensation ndi mlingo wa kuzizira-thaw akhoza kusinthidwa malinga ndi zosowa zenizeni za polojekitiyi.

Njira Ndi Chitetezo
1. Kusakaniza kovomerezeka: ufa 0.5 ~ 1.5% .Zamadzimadzi 2 ~ 3% "Kuwerengedwa ndi zinthu za gel, kusakaniza kumeneku ndiko kusakaniza kovomerezeka, ndipo chiwerengero chake chenicheni chiyenera kutsimikiziridwa molingana ndi momwe zinthu zilili.Findetermined pambuyo poyezetsa chiŵerengero cha kugwirizana.
2. Ufa wa mankhwalawa ukhoza kuwonjezeredwa mwachindunji kusakaniza kapena kugwiritsidwa ntchito pambuyo pa kutha.Madzi amayenera kuchotsera madzi omwe ali mu solution.Post postincorporation njira ndi yabwino.
3. Kutentha kwa simenti sikuyenera kupitirira 60 ℃. Izi ndizoyenera kumanga konkire ndi kutentha kwa tsiku ndi tsiku kupitirira 5 ℃.
4. Konkire yowonjezeredwa ku mankhwalawa iyenera kuwonjezera nthawi yosakaniza kwa 30 mpaka 60s.
5. Chogulitsacho chidzasungidwa pamalo ozizira ndi owuma.Pewani chinyontho ndi kuwonongeka.shelufu ya chaka chimodzi.
Utumiki waukadaulo
1. Malinga ndi momwe zinthu ziliri, kampani yathu imatha kupereka chithandizo choyenera kuukadaulo wa konkriti.
2. Malinga ndi zosowa za mnzathu, kampani yathu imatha kupereka ntchito zaukadaulo monga kapangidwe ka konkire kusakaniza kosakanikirana, kukhathamiritsa kwa njira yomanga (kufulumizitsa nthawi yomanga ndi kupulumutsa mtengo), kuwongolera njira yomanga, kukonza konkire ndi chithandizo ndi zina zokhudzana ndiukadaulo. .
