(Lub luag haujlwm ntawm Dej Reducer hauv Kev txo cov pob zeb tawg)

Pob zeb yog lub hauv paus ntawm kev tsim vaj tsev niaj hnub thiab kev tsim kho. Nws txhim kho peb lub tsev, chaw ua haujlwm, choj, thiab txoj kev. Tab sis txawm tias cov khoom zoo nkauj no muaj qhov tsis muaj zog: tawg. Pom cov kab nrib pleb hla ib txoj kev tshiab los yog lub hauv paus tsev yog kev poob siab. Nws qhia txog tej yam teeb meem. Cov dej reducers muab cov kev xaiv zoo. Paub txog lawv txoj haujlwm yog qhov tseem ceeb rau kev tsim kom muaj zog dua, ntau cov qauv ruaj khov. Cia saib seb qhov kev sib xyaw tseem ceeb no ua haujlwm li cas.

1. Dab tsi yog Water Reducer? .

Xav tias pob zeb yog kev sib xyaw ua ke, xuab zeb, pob zeb crushed, thiab dej. Dej yog qhov tseem ceeb. Nws ua rau cov pob zeb ua haujlwm tau zoo. Koj tuaj yeem tso nws thiab tsim nws. Tab sis ntawm no yog qhov teeb meem. Koj yeej xav tau dej tsawg dua li qhov koj xav tau rau cov tshuaj tiv thaiv uas ua rau pob zeb tawv. Cov dej ntxiv ua rau lub pob zeb puas. Nws kuj tsim shrinkage thaum nws dries tawm. Shrinking ua rau tawg. Yog li, qhov kev xaiv yog dab tsi? Siv dej tsawg dua. Tab sis kev siv dej tsawg dua ua rau kev sib xyaw ua ke thiab nyuaj rau kev koom tes nrog. Nws los ua nyuaj rau qhov chaw thiab xaus kom zoo. Qhov no yog qhov twg cov dej reducers tau muaj nyob rau hauv. Lawv yog cov tshuaj tshwj xeeb pab txhawb rau kev sib xyaw ua ke. Lawv txoj haujlwm tseem ceeb? Ua kom cov pob zeb ntws zoo dua tsis tas yuav ntxiv dej ntau ntxiv. Lawv xyaum cov roj nplua nyeem me me. Lawv txo qhov rubbing ntawm cov cement hais thiab lwm cov khoom xyaw. Qhov no qhia tias koj tuaj yeem ua tiav qhov kev ua haujlwm zoo ib yam, tib yam yooj yim ntawm kev tso kawm, tseem nrog dej tsawg heev. Koj tau txais ib qho kev sib xyaw uas yooj yim dua los daws tab sis muaj zog ntau dua thiab tsis tshua muaj kev cuam tshuam rau ziab thiab tawg. Cov dej reducers tseem hu ua plasticizers. Lawv yog cov cuab yeej tseem ceeb rau kev tsim vaj tsev niaj hnub.

2. Vim Li Cas Peb Thiaj Yuav Tsum Tau Cov Dej Dej kom tsis txhob sib cais? .

Pob zeb tawg vim ntau yam. Ib qho kev ua txhaum loj yog dej ntau dhau. Thaum cov pob zeb muaj dej ntau tshaj qhov xav tau, uas dej ntxiv nws thiaj li evaporates. Raws li cov dej tawm, lub pob zeb diminishes. Xav txog daim txhuam cev kom qhuav thiab ua kom me me. Qhob ua tib yam. Qhov no shrinkage ua rau sab hauv kev ntxhov siab thiab kev ntxhov siab. Yog tias cov pob zeb tsis muaj zog txaus los sawv ntsug rau cov kev ntxhov siab no, nws tawg. Txo cov khoom siv dej ncaj qha daws qhov teeb meem no. Cov dej tsawg txhais tau tias tsawg dua. Ntau tsawg shrinkage implies tsawg tawg. Cov dej reducers pab kom peb ua tiav cov khoom siv dej tsawg no. Lawv cia peb ua cov pob zeb uas yooj yim thiab txo qis hauv dej. Txawm li cas los xij, qhov zoo tshaj qhov tsuas yog txo qis qis. Cov dej tsawg dua kuj qhia tias muaj qhov tuab dua. Cov khoom ntim ua ke kom ruaj ntseg. Qhov no ua rau lub pob zeb muaj zog. Cov pob zeb muaj zog ntau dua yog qhov zoo dua ntawm kev tiv thaiv tawg los ntawm ntau yam kev ntxhov siab thiab, zoo li hnyav loads los yog kub hloov kho. Ntxiv rau, ib tug denser pob zeb yog tsawg permeable. Cov dej thiab cov tshuaj ua kom puas tsuaj pom tias nws nyuaj dhau los. Qhov no txhim kho qhov muaj zog thiab ruaj khov cov hlau sab hauv los ntawm xeb. Rusting steel expands thiab tuaj yeem ua rau splitting. Yog li, kev siv cov dej reducer tsim muaj cov tshuaj tiv thaiv kab mob: dej tsawg, tsawg shrinkage, tsawg tawg, siab zog, ntev dua zoo dua. Nws cuam tshuam nrog kev rhuav tshem ntawm nws cov peev txheej.

3. Tsuas yog Yuav Ua Li Cas Dej Reducer Hauv Qhov Tseeb Ua Haujlwm? .

Kev tshawb fawb tshawb fawb tom qab cov dej txo qis yog fascinating. Lawv feem ntau yog cov saw ntev ntev. Thaum ntxiv rau qhov sib tov, lawv koom nrog cov pob zeb. Cement particles ib txwm muaj lub ntsej muag sib luag. Cov globs no ntes dej hauv lawv. Xav txog ib txhais tes ntawm hmoov nplej; nws tuaj yeem tuav qee cov dej hauv sab hauv thiab yog tias nws zoo li qhuav tag. Cov dej khib nyiab no tsis ua haujlwm zoo. Nws tsuas yog ua kom qhov sib tov thicker. Cov dej reducer particles txuas lawv tus kheej mus rau thaj tsam ntawm cov cement hais. Lawv nqa tus nqi hluav taws xob. Qhov kev them nqi no ua rau cov pob zeb sib tsoo kom thawb rov qab sib txawv. Zoo li hlau nplaum thawb sib nrug. Qhov no repulsion cais cov globs. Cov pob zeb pob zeb nthuav tawm ntau sib npaug. Cov dej daig yog tso tawm. Cov dej tso tawm tam sim no ua haujlwm raws li cov khoom siv lubricating. Nws ua rau tag nrho cov kev sib xyaw ua ke ntau yooj yim dua. Cov pob zeb los ua kua ntau dua. Nws xav tau kev siv zog tsawg dua los tso dej, cheeb tsam, thiab ua kom tiav. Tag nrho qhov no tshwm sim thaum qhov tseeb ntawm cov dej hauv qhov sib xyaw yog tsawg dua qhov nws yuav yeej tsis muaj qhov sib xyaw.. Qhov tshwm sim yog lub pob zeb uas coj zoo li nws muaj dej ntau dua tab sis yeej muaj tsawg dua. Qhov kev txhim kho particle diffusion zoo li no ntxiv rau kev sib xyaw ntau dua. Qhov no uniformity pab lub pob zeb nce zog ntxiv mus tas li.
