Yuav Ua Li Cas Ntsuam Xyuas Qhov cuam tshuam ntawm Anti-static Terrazzo? Yuav Dragging Cov Khoom hnyav ua rau tawg

Kev sim txoj kev rau kev cuam tshuam ntawm kev tiv thaiv kev tiv thaiv - zoo li qub terrazzo thiab kev tsom xam ntawm kev cuam tshuam ntawm cov khoom hnyav
1, Kev sim txoj kev rau kev cuam tshuam kev ua haujlwm
Qhov cuam tshuam tsis zoo ntawm kev tiv thaiv - zoo li qub terrazzo yuav tsum tau soj ntsuam los ntawm kev ntsuas tus qauv los ntsuas nws lub peev xwm los tiv thaiv cov khoom hnyav. Cov txheej txheem kev sim thiab cov qauv tseem ceeb yog raws li hauv qab no:

poob ceeb thawj cuam tshuam kuaj
Khoom siv: Siv tus qauv poob rauj cuam tshuam kuaj tshuab nruab nrog kho qhov siab thiab qhov hnyav poob rauj.
Cov kauj ruam:
Kho cov qauv tiv thaiv- zoo li qub terrazzo (feem ntau 300mm x 300mm hauv qhov loj) ntawm lub rooj zaum xeem.
Lub rauj ntog los ntawm qhov siab ntawm qhov siab (xws li . 1m) thiab cuam tshuam rau thaj chaw nruab nrab ntawm cov qauv.
Saib xyuas seb puas muaj cov kab nrib pleb, puas lossis delamination ntawm qhov chaw ntawm cov qauv, sau cov kev cuam tshuam lub zog (xws li 50J, 100J) thiab qhov xwm txheej puas tsuaj.
Standard hauv paus: Xa mus rau "Technical Regulations for Anti static Construction of Building Ground Engineering" los yog cov qauv kev lag luam zoo sib xws, qhia meej txog kev sib raug zoo ntawm kev cuam tshuam lub zog thiab kev ua tsis tiav.
Kev suav ntawm kev cuam tshuam lub zog
Formula:
σ=
A
E
​

Ntawm lawv, $ \\ sigma $ yog qhov cuam tshuam lub zog (MPa), $ E $ yog lub zog cuam tshuam (J), thiab $ A $ yog qhov cuam tshuam ntawm tus qauv (mm ²).
Kev txiav txim siab: Yog tias tus qauv tsis muaj kab nrib pleb lossis kev puas tsuaj nyob rau hauv kev cuam tshuam lub zog ntawm 50-100J, nws ua tau raws li cov kev xav tau ntawm kev ua haujlwm siab.
Simulation ntawm kev siv tiag tiag scenarios
Simulate qhov xwm txheej ntawm cov khoom hnyav rub tawm hauv chav kuaj, siv cov menyuam lossis cov slider nrog qhov hnyav (xws li 100kg) kom rub rov qab thiab tawm ntawm cov qauv ntawm qhov ceev (xws li 1m / s) rau 100 zaug.
Saib xyuas qhov hnav, tawg, thiab kev hloov pauv hauv kev ua haujlwm tiv thaiv- zoo li qub los ntsuas lawv cov kav ntev.

2, Kev cuam tshuam ntawm cov khoom hnyav rub tawm los tiv thaiv - zoo li qub terrazzo
Kev ua tau zoo ntawm kev tiv thaiv- zoo li qub terrazzo nyob rau hauv cov khoom hnyav rub yuav tsum tau soj ntsuam zoo raws li cov khoom siv thiab kev tsim kho tshuab:

Khoom yam ntxwv zoo
Lub siab tawv thiab hnav tsis kam: Cov tshuaj tiv thaiv- zoo li qub terrazzo muaj Mohs hardness ntawm 6-7 qib, ze rau lub pob zeb ntuj, thiab tuaj yeem tiv taus kev sib txhuam thiab cov khoom hnyav crushing, txo kev ua haujlwm degradation los ntawm hnav.
Cov dej nqus dej tsawg: Cov dej nqus dej feem ntau yog tsawg dua lossis sib npaug li 0.5%, thiab nws tuaj yeem tuav ruaj khov tiv thaiv - zoo li qub kev ua haujlwm nyob rau hauv qhov chaw ntub dej, zam qhov txo qis ntawm kev nqus dej los ntawm kev nqus dej.
Impact resistant design: Los ntawm optimizing tus aggregate piv thiab binder lub zog, cov kev cuam tshuam kev cuam tshuam tuaj yeem tiv taus qhov cuam tshuam ntawm 50-100kg yam tsis muaj kev puas tsuaj, ua tau raws li qhov yuav tsum tau muaj ntawm kev lag luam scenarios.
Lub luag haujlwm tseem ceeb ntawm kev tsim kho tshuab
Grassroots kev kho mob: Yog hais tias qhov flatness ntawm cov hauv paus hniav tsis zoo los yog muaj hollowing, rub cov khoom hnyav yuav ua rau lub zos tawg vim muaj kev ntxhov siab.
Adhesive zog: Siv cov nplaum tshwj xeeb (xws li tiv thaiv- static terrazzo nplaum nrog lub zog nplaum Ntau dua lossis sib npaug li 1.5MPa) tuaj yeem tiv thaiv hauv pem teb hollowing thiab tev, thiab txhim khu kev tiv thaiv.
Daim phiaj sib koom tsim: Tsim nyog qhov chaw ntawm daim phiaj sib koom ua ke (qhov sib nrug tsawg dua lossis sib npaug li 6m) tuaj yeem tso tawm kev ntxhov siab thiab zam kev tawg tag nrho los ntawm kev hloov pauv kub lossis khoom hnyav dov.
Cov xwm txheej tiag tiag thiab kev txheeb xyuas tus qauv
Kev lag luam tus qauv yuav tsum tau ua: Raws li "Kev Ntsuas Kev Ntsuas rau Cov Txheej Txheem Zoo Zoo hauv Cov Khoom Siv Hluav Taws Xob" (SJ / T10694-2006), kev tiv thaiv zoo li qub terrazzo yuav tsum dhau qhov kev xeem "nto tsis kam, kev tiv thaiv" (ntau 1 × 10 ⁴ -1 × 10 ¹⁰ kev ua raws li qhov voltage Ω)<50V".
Kev ua haujlwm ntev ntev: Cov khoom siv zoo tiv thaiv- zoo li qub terrazzo tuaj yeem tiv taus cov khoom hnyav hnyav (xws li forklift thiab txee txav) tau ntev raws li kev tsim kho thiab kev saib xyuas, nrog rau qhov hnav tsis tshua muaj qis thiab qeeb degradation ntawm anti- zoo li qub kev ua tau zoo (feem ntau tseem siv tau rau ntau tshaj 10 xyoo).

3, Cov lus xaus thiab cov lus qhia
Impact resistance: Anti zoo li qub terrazzo tuaj yeem tshawb xyuas rau nws qhov kev cuam tshuam lub zog (50-100J yam tsis muaj kev puas tsuaj) thiab hnav tsis kam los ntawm kev poob rauj cuam tshuam kev sim thiab simulated cov khoom hnyav rub, ua tau raws li qhov yuav tsum tau muaj ntawm kev lag luam scenarios.
Qhov cuam tshuam ntawm kev thauj khoom hnyav: Raws li kev tsim kho kom raug (lub hauv paus tiaj tus, ruaj khov, sib koom ua ke tsim nyog) thiab kev saib xyuas tsis tu ncua (ntxuav, ya raws- pov thawj), cov khoom hnyav rub yuav tsis ua rau tawg lossis tsis ua haujlwm ntawm kev tiv thaiv - zoo li qub.
Kev xaiv tswv yim:
Qhov tseem ceeb yuav tsum tau muab rau cov khoom siv los tiv thaiv- zoo li qub terrazzo cov khoom uas muaj Mohs hardness ntawm ntau dua lossis sib npaug li 6 thiab qhov nqus dej tsawg dua lossis sib npaug li 0.5%.
Yuav tsum muaj chav tsev tsim kho kom muab daim ntawv qhia txog kev sib tw ua kom muaj zog (Ntau dua lossis sib npaug ntawm 1.5MPa) thiab daim phiaj sib koom tsim kev kos duab.
Tsis tu ncua xyuas qhov kev tiv thaiv saum npoo thiab kev sib txhuam ntawm qhov hluav taws xob kom ntseeg tau tias qhov ua tau zoo txuas ntxiv ntawm kev ua haujlwm zoo li qub.
