Mildew mupolycarboxylate superplasticizerzitha kukhudza mtundu wawo ndipo, zikavuta kwambiri, zimadzetsa zovuta zenizeni. Zotsatirazi ndizovomerezeka.

1. Sankhani sodium gluconate yapamwamba kwambiri ngati chigawo chochedwetsa.

Pakadali pano, pali opanga ambiri a sodium gluconate pamsika. Opanga omwe ali ndi machitidwe okhwima owongolera amatha kuwongolera shuga wotsalira ndi Aspergillus niger panthawi yopanga, potero amachepetsa kuwonongeka kwa ma polycarboxylate superplasticizers opangidwa ndi sodium gluconate.

2. Onjezani kuchuluka koyenera kosungira.

Kuonjezera kuchuluka koyenera kosungirako popanga polycarboxylate superplasticizer kumatha kuteteza kuwonongeka. Zosungirako zazikulu zomwe zili pamsika pano ndi monga sodium nitrite, sodium benzoate, ndi isothiazolinone. Isothiazolinone imagwiritsidwa ntchito kwambiri, yothandiza kwambiri, komanso yopanda poizoni. Ndi mankhwala ophera oxidizing okhala ndi pH yamitundu yosiyanasiyana, kupangitsa kuti ikhale chisankho choyenera popewa komanso kupha ma superplasticizers. Mlingo ndi 0.5-1.5 kg pa tani ya polycarboxylate superplasticizer.

3. Samalani ndi malo osungira.

Sungani polycarboxylate superplasticizer pamalo ozizira, olowera mpweya wabwino kutali ndi dzuwa. Kuyezetsa kunachitika pamene gawo limodzi la polycarboxylate superplasticizer linayikidwa mu botolo lozizira, losungirako dzuwa, pamene gawo lina linayikidwa mu botolo lomwe likuyang'anizana ndi dzuwa. Botolo poyang'anizana ndi dzuwa mwamsanga kuumbidwa ndi kusanduka wakuda.

Komanso, zotengera zosungiramo zapamwamba za polycarboxylate superplasticizer ziyenera kupangidwa ndi zinthu zopanda zitsulo, chifukwa dzimbiri zachitsulo zimatha kuwononga komanso kuwonongeka. Mwachitsanzo, akasinja azitsulo zosapanga dzimbiri amatha kupangitsa kuti superplasticizer ikhale yofiira, matanki achitsulo amatha kupangitsa kuti ikhale yobiriwira, ndipo akasinja amkuwa amatha kupangitsa kuti ikhale yabuluu.

4. Yerekezerani mwanzeru kuchuluka kwa polycarboxylate superplasticizer yomwe imagwiritsidwa ntchito pantchitoyi.

M'ma projekiti ena, kuchuluka kwa ma polycarboxylate superplasticizer kumavuta kuwongolera chifukwa cha zinthu monga momwe polojekiti ikuyendera komanso nyengo. Nthawi zina, polycarboxylate superplasticizer yasungidwa pamalopo kwa miyezi yopitilira itatu kapena kupitilira apo, zomwe zimayambitsa kuwonongeka pafupipafupi. Chifukwa chake, tikulimbikitsidwa kuti opanga azilumikizana ndi dipatimenti ya projekiti zokhudzana ndi kagwiritsidwe ntchito kazinthuzo ndi kuzungulira kwake asanaperekedwe, kuwonetsetsa kuti akugwiritsidwa ntchito moyenera komanso moyenera pakati pa kugwiritsidwa ntchito kwa polycarboxylate superplasticizer ndi kubwezeretsanso.

5. Kuchepetsa kugwiritsa ntchito zoteteza monga formaldehyde ndi nitrites.

Pakadali pano, ena opanga ma superplasticizer amagwiritsa ntchito zotetezera monga formaldehyde, sodium benzoate, ndi nitrites oxidizing kwambiri. Ngakhale kuti ndizotsika mtengo, zotetezerazi sizigwira ntchito. Kuphatikiza apo, formaldehyde imatha kuthawa pakapita nthawi, kutentha, ndi pH, zomwe zimapangitsa kuti mankhwalawa apitirire kuwonongeka. Ndibwino kuti mugwiritse ntchito ma biocides apamwamba ngati kuli kotheka. Pamatangi osungira owonongeka a superplasticizer, ayeretseni bwino musanadzazenso ndi polycarboxylate superplasticizer yatsopano.

Kuphatikiza apo, ma polycarboxylate superplasticizers okhala ndi nkhungu zochepa kwambiri, chithandizo cha kutentha, kuwonjezera hydrogen peroxide kapena madzi a caustic koloko, kapena njira zina zobwezeretsanso. Zolemba zofunikira zikuwonetsa kuti mankhwalawa amatha kubwezeretsa polycarboxylate superplasticizer kuzinthu zake zoyambirira, kukhala ndi mtundu wofanana ndi wazinthu zosapangidwa ndikuchotsa fungo.
