Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Nyob rau hauv lub tswv yim engineering, pob zeb tawg los ntawm shrinkage yog feem ntau. Nyob rau hauv lub pob zeb shrinkage qeb, yas shrinkage thiab qhuav shrinkage yog lub ntsiab ua rau pob zeb ntim deformation, thiab spontaneous shrinkage thiab carbonization shrinkage. Lub ntsiab yog vim li cas rau hom kev tawg yog tias cov pob zeb tsis tau ua haujlwm zoo tom qab hardening thiab sib sau, xws li ya raws, kev txuag hluav taws xob, thiab kev tswj xyuas tsis nyob hauv qhov chaw, pob zeb nto cua, thiab hnub, uas ua rau saum npoo av noo sai heev, loj shrinkage.
Cov pob zeb sib sib zog nqus tau dhau los ua qhov tseem ceeb ntawm cov pob zeb niaj hnub no vim nws qhov kev ua tau zoo seismic, kev txuag hluav taws xob, thiab hluav taws kub tsis kam thiab nws lub teeb zoo. Lub shrinkage ntawm lub teeb yuag yog yooj yim rau qhuav tawg thaum ntxov, uas yuav ua rau cov pob zeb ua kom puas thiab ua rau lub neej ua haujlwm ntawm cov pob zeb luv.
Tom qab ntau qhov kev sim thiab ntau xyoo ntawm kev paub txog kev ua pob zeb sib sib zog nqus, nws pom tias ntxiv polypropylene fiber ntau (PP fiber ntau) los yog polyvinyl cawv fiber ntau (PVA fiber ntau) thiab tus neeg sawv cev nthuav dav rau cov pob zeb sib sib zog nqus tuaj yeem txo nws qhov shrinkage tus nqi, thiab qhov sib ntxiv ntawm tus neeg sawv cev nthuav tawm tau pom tseeb shrinkage txo cov nyhuv. Cov txiaj ntsig zoo tshaj plaws yog kev sib koom ua ke ntawm fiber ntau thiab tus neeg sawv cev nthuav dav, qhov sib xyaw ua ke ntawm ob qho tib si zoo dua li cov nyhuv ntawm ob leeg ib leeg, kev sib koom ua ke ntawm fiber ntau thiab tus neeg sawv cev expansive shrinkage tus nqi yog me dua li cov pob zeb zoo tib yam.
Fiber txo qhov shrinkage ntawm lub ntsiab yog vim li cas nyob rau hauv lub mix rau hauv lub teeb yuag pob zeb, tag nrho cov fiber ntau yuav ua tau heev complex peb seem chaos system, thiab tuaj yeem cuam tshuam ib feem ntawm kev poob dej, ntxiv rau, kev nthuav dav ntawm fiber ntau tuaj yeem thaiv qhov microfracture zoo, kom tsis txhob muaj cov kab nrib pleb tsis tu ncua ua kom txo tau qhov shrinkage ntawm pob zeb.
Expansion tus neeg saib xyuas kom txo tau lub shrinkage ntawm lub ntsiab yog vim li cas nyob rau hauv lub sib tov rau hauv lub teeb yuag pob zeb expansive tus neeg sawv cev tuaj yeem tshwm sim thaum ntxov anhydrous calcium aluminium sulfate cov tshuaj tiv thaiv., nyob rau hauv nruab nrab lub sij hawm yuav tsim alunite, maj mam mus rau hauv lub teeb hnyav pob zeb expansive tus neeg saib xyuas thiab nrog dej tom qab yuav tsim ntau expansion sib koom ua ke crystalline compound, ua rau kev nthuav dav ntawm cov pob zeb hauv ib qho, nrog dawb shrinkage ntawm lub teeb yuag pob zeb tshem tawm ib leeg tawm.
Los xaus, vim qhov sib txawv ntawm shrinkage foundation ntawm fiber ntau thiab expansive agent, kev sib koom ua ke ntawm fiber ntau thiab expansive tus neeg sawv cev tuaj yeem txhim kho kev ua haujlwm ntawm kev sib tsoo ntawm cov pob zeb sib sib zog nqus., yog li txhawm rau txhim kho kev siv kev ua haujlwm ntawm lub zog siab lub teeb yuag hauv engineering.
Cie-China.org yog tus thawj coj ua npuas dej ua ke muab kev pabcuam ua npuas ncauj ua npuas ncauj, superplasticizer,ua npuas ncauj qhob zog enhancer rau lub teeb yuag pob zeb, CLC blocks. Yog koj tab tom nrhiav foaming tus neeg sawv cev, thov koj txhob xav li cas tiv tauj peb.
