Redispersible polymer hmoov (RDP) yog dej-soluble hmoov polymer emulsion. Cov khoom siv no yog siv dav hauv kev tsim kho kev lag luam, feem ntau yog cov ntawv khi rau cov cement thiab lwm yam khoom siv hauv tsev. Lub zog daim ntawv cog lus ntawm RDP yog qhov tseem ceeb rau nws daim ntawv thov vim nws ncaj qha cuam tshuam rau cov khoom ntawm cov khoom kawg. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum muaj ib txoj hauv kev zoo thiab txhim khu kev qha los ntsuas lub zog ntawm RDP.
Kev sim
Khoom siv
Cov ntaub ntawv xav tau los ua qhov kev xeem no yog raws li hauv qab no:
1. RDP piv txwv
2. Sandblasted aluminium substrate
3. Resin impregnated ntawv (300um thickness)
4. Dej-raws li nplaum nplaum
5. Tensile kuaj tshuab
6. Vernier caliper
xeem qhov kev pab cuam
1. Kev npaj cov qauv RDP: cov qauv RDP yuav tsum tau npaj nrog cov dej tsim nyog raws li cov chaw tsim khoom tau teev tseg. Cov qauv yuav tsum tau npaj raws li daim ntawv thov.
2. Kev npaj substrate: Aluminium substrate tom qab sandblasting yuav tsum tau ntxuav thiab qhuav ua ntej siv. Tom qab ntxuav, qhov roughness ntawm qhov chaw yuav tsum tau ntsuas nrog lub vernier caliper.
3. Daim ntawv thov ntawm RDP: RDP yuav tsum tau siv rau lub substrate raws li cov neeg tsim khoom cov lus qhia. Lub thickness ntawm zaj duab xis yuav tsum tau ntsuas nrog ib tug vernier caliper.
4. Kho: RDP yuav tsum kho nyob rau hauv lub sij hawm teev los ntawm cov chaw tsim tshuaj paus. Lub sijhawm kho yuav txawv raws li hom RDP siv.
5. Daim ntawv thov ntawm resin impregnated daim ntawv: Resin impregnated ntawv yuav tsum tau txiav mus rau hauv ib daim hlab uas tsim nyog loj thiab zoo li. Daim ntawv yuav tsum tau muab sib npaug nrog cov nplaum nplaum dej.
6. Cov ntawv nplaum nplaum nplaum: Cov nplaum nplaum nplaum yuav tsum muab tso rau ntawm RDP coated substrate. Lub teeb siab yuav tsum tau siv los ua kom muaj kev sib raug zoo.
7. Kho: Cov nplaum yuav tsum kho tsis pub dhau lub sijhawm teev tseg los ntawm cov chaw tsim khoom.
8. Tensile xeem: Load tus qauv mus rau hauv lub tensile xeem tshuab. Tensile zog yuav tsum tau sau tseg.
9. Kev suav: Lub zog ntawm daim ntawv cog lus ntawm RDP yuav tsum tau muab xam raws li lub zog yuav tsum tau cais RDP coated substrate los ntawm daim ntawv daim kab xev faib los ntawm thaj tsam ntawm RDP coated substrate.
nyob rau hauv xaus
Txoj kev xeem yog ib txoj hauv kev yooj yim thiab siv tau zoo los ntsuas RDP daim ntawv cog lus lub zog. Txoj kev no tuaj yeem siv rau hauv kev tshawb fawb thiab kev lag luam chaw kom ntseeg tau tias kev ua tau zoo ntawm RDP hauv cov cement thiab lwm yam khoom siv. Kev siv cov qauv no tuaj yeem pab txhim kho kev tswj xyuas zoo thiab kev tsim khoom hauv kev tsim kho kev lag luam.
