Kho kom meej pob zeb formwork Los txhim kho lub thawv sib nqus yog cov khoom siv sib nqus tshwj xeeb tsim rau kev kho cov precast pob zeb. Piv nrog tsoos mechanical kho cov hau kev xws li ntsia hlau thiab cov txiv ntoo, lub thawv sib nqus no muaj cov txiaj ntsig hauv qab no:
Txo cov txheej txheem thiab lub sijhawm ntawm kev txhim kho cov qauv thiab txhim kho kev ua haujlwm (nce txog 70%).
Nws muaj lub zog nqus thiab tuav lub zog, kev ua haujlwm yooj yim, muaj kev nyab xeeb thiab txhim khu kev qha.
Tsis tas yuav tsum muaj vuam xav tau, yog li cov ntaub ntawv pwm yuav tsis raug puas ntsoog.
Tus nqi yog tsawg, thiab tus nqi tuaj yeem rov qab tau zoo nyob rau hauv li 3 lub hlis. Tsis tas yuav xaiv cov thawv sib nqus sib txawv rau cov khoom sib txawv. Ib lub thawv sib nqus tuaj yeem siv nrog cov khoom sib txawv kom tau raws li cov kev xav tau ntau dua.
Kev khiav hauj lwm kub
Shuttering hlau nplaum feem ntau yog ua los ntawm sintered ndfeb cov hlau nplaum cov hlau nplaum cov ntaub ntawv.
Ob lub zog yog qhov tseem ceeb heev rau cov hlau nplaum shuttering:
1) Residual Magnetism (BR): Tom qab cov ntaub ntawv ferrigagetic yog cov hlauetized thiab cov khoom sib nqus tau muab tshem tawm ntawm cov hlau nplaum ntawm cov hlau nplaum shuttering. Ntau dua cov hlau nplaum kev ua haujlwm, tus br.
2) Intrinsic hlaunivity (HCJ): Intrinsic hlaunivity yog qhov taw qhia loj ntawm lub peev xwm ruaj khov lossis lwm yam demagnetization cuam tshuam los tswj nws lub xeev motetization qub. Nws cuam tshuam ncaj qha cuam tshuam rau kev ua yeeb yam ntawm cov hlau nplaum. Nyob rau hauv cov ntaub ntawv ntawm atrenuation los ntawm cov chaw nyob sab nraud (xws li thim rov qab sib nqus daim teb, kub, thiab lwm yam.

Nws tuaj yeem pom tau tias qhov ntau tshaj plaws ua haujlwm kub ntawm qhov qis tshaj plaws-ua haujlwm ndfeb hlau nplaum khoom kuj tseem 80 degrees. Yog li no, feem ntau, thawv thau tau yog ua los ntawm n lossis M-qib NdFeb cov khoom. Yog tias peb tsim cov PC Cheebtsam, qhov kub thaum lub sijhawm kho kom qis dua 65 degrees tsis cuam tshuam rau lub magnetism ntawm lub thawv sib nqus. Yog tias lub thawv sib nqus tau yuav tsum ua haujlwm ntawm qhov kub ntawm 80 degrees lossis siab dua, qib siab ntawm NDFEX cov khoom siv tau.
Qhov chaw sib nqus yog qhov tsis sib xws thiab tsis tuaj yeem sib haum nrog cov ntaub ntawv pwm
1. Hauv qab ntawm lub thawv sib nqus yuav tsis muaj hlau txuas xws li hlau xaim thaum ua haujlwm, uas yuav ua rau lub thawv nqus dej tsis muaj zog.
2. Vim tias cov qauv ntawm cov hlau nplaum thaiv nws tus kheej, yog tias cov txheej txheem ntau lawm, nws kuj tseem tsis ncaj ncees), ua rau muaj kev txo qis ntawm lub thawv sib nqus.
Lub cev hlau nplaum hauv cov hlau nplaum thaiv yog puas
Lub cev lub cev ntawm sintered ndFeb cov khoom siv tawv thiab nkig, thiab yooj yim rau corbre, thiab yooj yim rau corocket nrog sab nraud ntawm cov hlau nplaum tsis tuaj yeem puas. Yog tias cov hlau nplaum sab hauv lub pob sib nqus tau tawg thiab lub tshuab lub cev puas puas, lub zog nqus ntawm lub sib nqus yuav txo qis.
Yog li ntawd, thaum sib dhos cov hlau nplaum thiab cov hlau sib dhos ua ke rau hauv cov hlau nplaum, qhov saum npoo ntawm cov hlau nplaum yuav tsum qis li lub dav hlau ntawm cov hlau bar, uas tuaj yeem ua kom muaj kev sib tsoo. Cov hlau nplaum nws tus kheej kuj xav tau ib txheej tiv thaiv kom tsis txhob muaj kev puas tsuaj thiab xeb rau lub cev.
Txhawm rau tiv thaiv lub cev hlau nplaum, SAixin cov tuam txhab siv cov khoom siv hluav taws xob txawv txav ntawm txhua lub raj hlau, thiab tshuab hluav taws xob, lub hlau nplaum stainless me ntsis.
