Feature ntawm aluminium formwork tsim
Vim li cas aluminium formwork ua rau muaj kev ntsuas qis dua li cov ntoo formwork thaum siv tib lub pob zeb ua ke hauv tib qhov project thiab tib lub hnub nyoog, tshwj xeeb tshaj yog thaum lub caij ntuj no tsim? Qhov no feem ntau yog vim muaj cov khoom siv ntawm aluminium alloy, xws li thermal conductivity, tsis tshua muaj dej nqus, thiab airtightness zoo. Txhawm rau daws qhov teeb meem no, peb yuav tsum tau ntsib qhov xwm txheej tam sim no, txheeb xyuas cov laj thawj hauv qhov tob, thiab tsim cov phiaj xwm kev tiv thaiv kom tsis tu ncua txhim kho qhov zoo ntawm cov qauv kev tsim vaj tsev.
Piv nrog rau cov ntoo formwork, aluminium formwork muaj qhov zoo zoo xws li tag nrho cov rigidity ntau dua, ntau dua cov qauv kev ruaj ntseg, thiab ntau dua ntawm kev rov siv dua, thiab nws ua raws li lub tswv yim ntawm siab -zoo ntsuab kev loj hlob, yog li ua lub hauv paus formwork system nyob rau hauv kev tsim kho engineering.
Nyob rau tib lub sijhawm, peb yuav tsum tawm tsam qhov teeb meem: lub zog rov qab los ntawm aluminium formwork pob zeb ntawm qhov chaw tsim kho tam sim no feem ntau tsis ua raws li cov qauv. Kev tshuaj xyuas cov xwm txheej tseem ceeb hauv xyoo tas los no qhia txog cov laj thawj tseem ceeb hauv qab no rau qhov teeb meem no: Aluminium formwork muaj thermal conductivity, uas ua rau poob kub sai thaum lub sij hawm ua vaj tse hydration thiab qeeb thaum ntxov lub zog loj hlob, tshwj xeeb tshaj yog thaum lub caij ntuj no kev tsim kho.
Aluminium formwork muaj qhov nqus dej tsawg, ua rau muaj dej siab -cement piv rau ntawm pob zeb. Kev vibration tuaj yeem yooj yim ua rau muaj qhov qis -lub zog laitance txheej ntawm qhov chaw.
Aluminium formwork muaj cov khoom sib khi zoo, ua rau nws nyuaj rau cov npuas hauv huab cua kom khiav tawm thaum lub pob zeb nchuav, ua rau tsim cov npuas npuas ntawm qhov chaw.
Hais txog cov teeb meem no thiab tshuaj xyuas lawv cov laj thawj yog txhawm rau ua kom muaj kev ntsuas meej thiab kev tiv thaiv kev tiv thaiv kom txo tau qhov tshwm sim ntawm cov pob zeb tsis xws luag thiab tsis muaj zog rebound lub zog thaum lub sij hawm txhuas formwork tsim. Cov nram qab no yog cov lus pom zoo: Vim yog lub thermal conductivity ntawm aluminium formwork, uas ua rau qeeb ntawm cov txheej txheem dej thaum ntxov, lub sij hawm demolding yuav tsum raug txiav txim siab raws li qhov kub thiab txias los tiv thaiv kev tawg ntxov ntxov thiab kev puas tsuaj rau saum npoo. Thaum lub sij hawm kho, lub pob zeb yuav tsum tau them tag nrho thiab watered, los yog ib tug hydration curing tus neeg sawv cev yuav tsum tau siv los txhim kho lub zog saum npoo. Thaum lub ambient kub tsis tshua muaj, kev txuag hluav taws xob thiab kev khaws cia noo noo yuav tsum tau siv los ua kom zoo dua qhov dej ntawm qhov chaw thiab txhawb kev txhim kho lub zog.
Txhawm rau daws qhov teeb meem ntawm txheej laitance ntawm qhov chaw uas tshwm sim los ntawm kev nqus dej tsawg ntawm aluminium formwork, cov dej - cement ratio thiab admixtures yuav tsum tau ua kom zoo dua thaum lub sij hawm tsim kev sib xyaw ua ke. This reduces the precipitation of free water, improves surface density, and accelerates early strength gain.
Muab hais tias qhov zoo tshaj plaws sealing zog ntawm txhuas formwork tuaj yeem ua rau saum npoo av npuas, ntau -qib qhob mix tsim xav tau kev ua kom zoo dua. Los ntawm kev siv cov txheej txheem ua kom zoo dua qub, qhov ntim ruaj khov ntawm cov pob zeb ua kom zoo dua qub, porosity thaum lub sij hawm hardening yog txo, thiab tiam ntawm huab cua npuas nyob rau hauv lub pob zeb nws tus kheej yog minimized. Nyob rau tib lub sijhawm, cov txheej txheem kev vibration sib txuas ua ke siab - zaus vibrators thiab nto qis - zaus vibrators yog ua haujlwm los xyuas kom meej txaus compaction ntawm ob sab hauv thiab sab nrauv ntawm cov pob zeb, zoo tshem tawm cov npuas npuas thiab alleviating nto looseness.
Tsis tas li ntawd, nyob rau hauv qee qhov haujlwm, yog tias aluminium formwork nto tsis huv huv, cov zaj duab xis du tsis tuaj yeem tsim, ua rau lub pob zeb tsis sib xws, qhov ntom ntom tsis txaus, thiab yog li ntawd, lub zog tsis txaus. Yog li ntawd, aluminium formwork yuav tsum tau ntxuav kom huv si ua ntej thov tso tawm tus neeg sawv cev. Rau reusable aluminium formwork, qhov nto passivation zaj duab xis yuav tsum tau xyuas tsis tu ncua thiab kho kom sai.
