Kwezinye iinkqubo zokuveliswa kwekhonkrithi, umakhi uhlala engeza i-agent ethile yokunciphisa amanzi, enokugcina i-slump yekhonkrithi, ukuphucula ukusasazeka kweengqungquthela zekhonkrithi, kunye nokunciphisa ukusetyenziswa kwamanzi. Nangona kunjalo, kukho i-drawback yokuba i-agent yokunciphisa amanzi i-surfactant, eya kubangela ukuveliswa kwe-foam, okuya kuchaphazela amandla kunye nomgangatho wekhonkrithi. Ukuba i-foam yenziwa ngexesha lokwakha, kufuneka isuswe ngexesha. Kukho i-defoamer enokuba kakhulu Eyona ndlela yokuphelisa i-foam yekhonkrithi yi-samente yamanzi yokunciphisa i-agent defoamer.

Ukusebenza kokuthoba ugwebu lwe-agent yokunciphisa amanzi e-samente:

Idefoamer ubukhulu becala yenziwe ngepolyether elungisiweyo kwaye yeyepolyetherdefoamer. Idefoamer ayiyi kuchaphazela kakubi iipropati ezibalulekileyo zekhonkrithi ekusetyenzisweni kwe-foam yekhonkrithi, kwaye ingaba nemiphumo ezinzileyo ye-defoaming kunye ne-foam. Idefoamerine-dispersibility elungileyo kwi-foam yekhonkrithi, kwaye inokusasazwa ngokukhawuleza kwi-foam yekhonkrithi ukufezekisa ukuphulwa kwe-foam yokugqibela kunye nesiphumo sokwenza ugwebu. Ukongeza kokukhupha ugwebu kunye nokuchasana nogwebu lwekhonkrithi, inokukhupha amagwebu kubushushu obuphezulu kunye neasidi eyomeleleyo kunye nendalo yealkali.

Isiphumo sokwenza amagwebu se-agent yokunciphisa amanzi e-samentedefoamer:

Isiphumo sedefoamer kwintsebenzo yekhonkrithi ubukhulu becala ibonakala kwiinkalo ezimbini: kwelinye icala, inokuphelisa amaqamza omoya phakathi kwekhonkrithi kunye ne-formwork ukuya kwinqanaba elithile, ukukhusela ngokufanelekileyo okanye ukuphelisa isizukulwana se-honeycomb kunye neendawo eziphawulweyo kumphezulu wekhonkrithi, kwaye wenze umphezulu wekhonkrithi ube nomcaba oPhezulu kunye neglosi. Kwelinye icala, idefoamer inokuphelisa ubuninzi beebhubhu zomoya kwikhonkrithi, ukunciphisa umxholo womoya kunye ne-porosity yangaphakathi yekhonkrithi, kunye nokuphucula iimpawu zomatshini kunye nokuqina kwekhonkrithi.

Indlela yokusebenzisa i-agent yokunciphisa amanzi e-samentedefoamer:

1. Xa idefoamer isetyenziselwa ukuveliswa kwe-foam yekhonkrithi kunye ne-agent yokunciphisa amanzi, i-concrete foam slurry iya kuba yinto enqabileyo. Kuyacetyiswa ukuba udibanisedefoamer ngokukhawuleza xa i-foam iveliswa, enokuphelisa ngokukhawuleza iibhubhu ezinkulu ezingalinganiyo kwi-foam yekhonkrithi kwaye ingenise iyunifomu Iibhubhu zomoya ezincinci zinokunyusa ubulukhuni bekhonkrithi.

2. Idefoamer ine-dispersibility eyomeleleyo kwaye kulula ukwahlula emva kokubekwa ixesha elide. Kunconywa ukuba ukuxuba okuqhubekayo kwenziwe ngexesha lokususwa kwe-foam yekhonkrithi.

3. Idefoamer isenokuthotywa ngenxa yealkalinity yayo, ngoko ke nceda uphephe ukuyisebenzisa xa ixabiso le-pH lingaphezulu kwe-10.
