Mune mamwe maitiro ekugadzira kongiri, muvaki anowanzo wedzera imwe inoderedza mvura, iyo inogona kuchengetedza kudonha kwekongiri, kunatsiridza kupararira kwekongiri zvimedu, uye kuderedza kushandiswa kwemvura. Zvisinei, pane kukanganisa kuti mvura inoderedza mumiririri ndeye surfactant, iyo inotungamirira kuchizvarwa chefuro, icho chichakanganisa simba uye kunaka kwekrete. Kana furo rakagadzirwa panguva yekuvaka, inoda kubviswa nenguva. Iko kune defoamer inogona kuve yakanyanya Nzira yakanakisa yekubvisa kongiri furo simende yemvura inoderedza agent defoamer.

Defoamer kuita kwesimende mvura inoderedza agent defoamer:

Thedefoamer inonyanya kugadzirwa nepolyether yakagadziridzwa uye ndeye polyetherdefoamer. Thedefoamer haizokanganisa zvinhu zvakakosha zvekongiri mukushandiswa kwekongiri furo, uye inogona kuve yakagadzikana defoaming uye furo kudzvinyirira mhedzisiro. Thedefoamerine dispersibility yakanaka mufuro rekongiri, uye inogona kukurumidza kuparadzirwa mufuro rekongiri kuti iwane yekupedzisira kuputswa kwefuro nekubvisa furo. Pamusoro pekubvisa furo uye anti-foaming mukongiri furo, inogona zvakare kubvisa furo mukupisa kwakanyanya uye yakasimba asidhi uye alkali nharaunda.

Iyo defoaming mhedzisiro ye simende mvura inodzikisa agentdefoamer:

Mhedzisiro yedefoamer pamusoro pekuita kwekongiri kunonyanya kuratidzwa muzvikamu zviviri: kune rumwe rutivi, inogona kubvisa mabhubhu emhepo pakati pekongiri uye formwork kune imwe nhanho, kudzivirira kana kubvisa chizvarwa chehuchi uye nzvimbo dzakaiswa pockmark pamusoro pekongiri, uye ita kuti pamusoro pekongiri ive neHigh flatness uye kupenya. Ukuwo, thedefoamer inogona kubvisa huwandu hwakawanda hwemhepo inoputika mukrete, kuderedza mhepo yemhepo uye mukati me porosity yekrete, uye kuvandudza maitiro emagetsi uye kusimba kwekrete.

Maitiro ekushandisa simende mvura yekudzikisa agentdefoamer:

1. Kana iyodefoamer inoshandiswa mukugadzirwa kwekongiri furo ine mvura inoderedza mumiririri, iyo kongiri foam slurry ichave yakanamatira. Zvinokurudzirwa kuwedzeradefoamer nokukurumidza apo furo rinogadzirwa, iro rinogona kukurumidza kubvisa mabhuru makuru asina kuenzana muhutu hwekrete uye kuunza yunifomu Mapupu emhepo maduku anogona kuwedzera kuoma kwekrete.

2. Thedefoamer ine simba dispersibility uye iri nyore kupatsanura mushure mekuiswa kwenguva refu. Zvinokurudzirwa kuti kusanganiswa kunoramba kuchiitwa panguva yekubviswa kwekrete foam.

3. Thedefoamer inogona kuderedzwa nekuda kwealkalinity yayo, saka ndapota dzivirira kuishandisa kana iyo pH kukosha iri pamusoro pegumi.
