Momwe Mungakonzere Nkhani za Foam mu Kugaya Simenti: Chitsogozo cha Gawo ndi Gawo la Ma Defoam Ochita Bwino Kwambiri

The Mill Room Nightmare: Nkhani Yomwe Mukuidziwa

Taganizirani izi: Zili choncho 2:00 AM. Wothandizira chipinda chowongolera amakuyimbirani. Ma amp amphero ndi olakwika. Kupanikizika kosiyana ndi kukwera. Mukudziwa tanthauzo lake - thovu. Chachikulu, bedi la thovu lokhazikika likutsamwitsa chopatula chanu. Kupanga kukutsika. Kugwiritsa ntchito mphamvu kukuchulukirachulukira. Mwayesa chinyengo chilichonse. Munawonjezeranso thandizo logaya. Zinapangitsa kuti zinthu ziipireipire. Munabwerera m'mbuyo. Tsopano chigayo chikunjenjemera.

Ndakhala moyo uwu. Za 20 zaka, Ndawonapo ogwira ntchito akumenya nkhondoyi. Kaŵirikaŵiri vuto silikhala chithandizo chogaya chokha. Vuto ndiloti chithovu chosalamulirika. Njira yothetsera vutoli ndi yosankhidwa bwino ndi kupatsidwa mlingo mkulu dzuwa defoamer kwa konkire zothandizira kugaya. Izi si nthanthi. Iyi ndi physics. Nkhaniyi imakupatsani masitepe enieni kuti mukonze.

1. Dziwani Mdani: Chifukwa Chimene Chithovu Chimapanga Mu Mgayo Wanu

Chithovu sichingochitika mwachisawawa. Ndi zotsatira zachindunji za chemistry pamwamba. Pa akupera, mumalenga mwatsopano, malo othamanga kwambiri a clinker ndi gypsum. Mamolekyu anu othandizira kugaya-maamine, glycols, polyols - adsorb pamalo awa. Iwo amachepetsa agglomeration. Amawongolera kuyenda. Zimenezo ndizabwino.

Koma mamolekyu omwewa amakhala ngati ma surfactants. Amachepetsa kupsinjika kwamtundu uliwonse madzi kupezeka. Ngakhale kufufuza chinyezi (kuchokera ku gypsum kutaya madzi m'thupi kapena mpweya wabodza) amapanga lamellae yamadzimadzi. Mpweya wonyezimira umatsekeredwa. Zotsatira zake ndi khola, chithovu chosalekeza.

• Chifukwa choyamba: Surfactant zochita za akupera thandizo formulation palokha.
• Chifukwa chachiwiri: Mchere wachilengedwe wochokera ku clinker womwe umakhazikitsa thovu lamellae.
• Choyambitsa: Kukhalapo kwa nthunzi yamadzi ndi kulowetsedwa kwa mpweya m'thupi la chigayo.

Chithovu ichi sichingokhala pamenepo. Imazunguliranso. Zimamanga pamasamba olekanitsa. Zimachepetsa kugawa bwino. Zimakupangitsani kuchepetsa kuchuluka kwa chakudya. Mukutaya zomwe mukuchita. Mumawotcha mphamvu zambiri pa tani. Apa ndi pamene mkulu dzuwa defoamer kwa konkire zothandizira kugaya amalowa mchitidwe.

2. Kumvetsetsa Njira: Momwe Defoamers Amapha Chithovu

Defoamer si mankhwala wamba. Ndikanthu kopangidwa mwaluso. Iyenera lowetsani thovu lamella, kufalitsa, ndi sokoneza khoma la buluu. Pali njira zitatu zosiyana:

• Kulowa: Dontho la defoamer liyenera kukhala locheperako kuposa lamadzimadzi ochita thovu. Zimangolowera mu lamella.
• Kufalikira: Dontho la defoamer limafalikira pamwamba pa kuwira. Izi zimapanga malo owonda. Lamella imakhala yofooka.
• Kuthamanga ndi Kugwa: Dontholo limalumikiza mbali zonse za lamella. Kanemayo akuwonda mpaka pazovuta kwambiri. Kuwiraku kumang’ambika.

A mkulu dzuwa defoamer kwa konkire zothandizira kugaya imapangidwira chemistry iyi. Si pepala wamba kapena defoamer utoto. Imapangidwa kuti ikhale yogwira mtima pamakameta apamwamba, kutentha kwambiri, ndi malo okhala ndi mankhwala ovuta a mphero ya simenti.

2.1. Silicone vs. Non-Silicone: Kusankha Kovuta

Muli ndi mabanja awiri oyambirira. Kusankha kwanu kumadalira zofuna zanu zapansi.

• Ma Defoam Opangidwa ndi Silicone: Zamphamvu kwambiri. Mlingo wochepa kwambiri (20 ku 100 ppm). Kufalikira kwabwino kwambiri. Chenjezo: Nthawi zina zimatha kuyambitsa kuwonongeka kwa konkriti ngati mutamwa mowa mopitirira muyeso. Gwiritsani ntchito kokha ngati kasitomala wanu alola kutsata kwa silicone.
• Non-Silicone (Zachilengedwe) Zosokoneza: Mlingo wokwera pang'ono (100 ku 500 ppm). Kugwirizana bwino ndi polycarboxylate ether (PCE) superplasticizers mu konkriti. Ndibwino kugwiritsa ntchito zomangamanga zapamwamba kwambiri. Chisankho chokondeka chamitundu yambiri yamakono yothandizira pogaya.

Ndikupangira osakhala silicone pafupifupi onse akupera simenti. Malire achitetezo ndi okulirapo. Kugwirizana ndikwapamwamba.

3. Sankhani Kumanja Product: Zofunikira zisanu ndi chimodzi zaukadaulo
