Recispersible polymer hmoov (RDP) yog dej-soluble hmoov polymer emulsion. Cov khoom siv no tau siv nyob rau hauv kev tsim kho kev tsim kho, feem ntau raws li lub phau ntawv rau cov cement thiab lwm cov ntaub ntawv hauv tsev. Qhov sib khi ua lub zog ntawm RDP yog qhov ntsuas tseem ceeb rau nws daim ntawv thov raws li cuam tshuam ncaj qha rau cov khoom ntawm cov khoom kawg. Yog li ntawd, nws yog qhov tseem ceeb kom muaj txoj kev ntsuas raug thiab txhim khu kev qha kom ntsuas cov nyiaj ntawm RDP.
Txoj kev xeem
Khoom
Cov ntaub ntawv yuav tsum tau ua qhov kev ntsuas no yog raws li hauv qab no:
1. Rdp Piv Txwv
2. Sandblasted Txhuas Substrate
3. Resin Impregnated Ntawv (300um thickness)
4. Dej-based nplaum
5. Tensile Kuaj Tshuab
6. Vernier caliper
Kev Kawm Xeem
1. Kev npaj ntawm RDP cov qauv: RDP cov qauv yuav tsum tau npaj nrog cov dej uas tsim nyog raws li cov chaw tsim khoom. Cov qauv yuav tsum tau npaj raws li cov cai sau.
2. Substrate Kev Npaj: Lub aluminium substrate tom qab sandblasting yuav tsum tau ntxuav thiab qhuav ua ntej siv. Tom qab tu, qhov chaw ntawm qhov chaw mos yuav tsum ntsuas nrog tus caliper vernier.
3. Daim ntawv thov ntawm RDP: RDP yuav tsum tau thov rau txheej txheej raws li cov chaw tsim khoom cov lus qhia. Lub thickness ntawm zaj duab xis yuav tsum ntsuas siv vernier caliper.
4. Kho: RDP yuav tsum kho tau tsis pub dhau lub sijhawm teev los ntawm cov khw. Kev kho lub sijhawm yuav sib txawv raws li hom RDP siv.
5. Kev thov ntawm Resin Ipration Ntawv: Resin Ipration Daim Ntawv yuav tsum tau txiav mus rau hauv ib daim hlab ntawm qhov loj me thiab cov duab. Daim ntawv yuav tsum yog tusyees coly nrog dej-ua nplaum nplaum.
6. Stips daim ntawv txheej txheem: cov nplaum nplaum cov ntawv sau yuav tsum muab tso rau ntawm RDP txheej txheej. Lub teeb siab yuav tsum tau siv rau kev ua kom tiav.
7. Kho: cov nplaum yuav tsum kho tau tsis pub dhau lub sijhawm teev los ntawm cov khw.
8. Tensile Xeem: Thauj cov qauv rau hauv lub tshuab kuaj Tensile. Lub zog tensile yuav tsum tau sau cia.
9. Xam: Cov nyiaj sib txuam ntawm RDP yuav tsum tau muab cais ua cov kab xev muab faib los ntawm thaj chaw RDP ntawm RDP coated sasttrate.
Hauv kev xaus
Txoj kev xeem yog ib txoj kev yooj yim thiab raug nqi ntawm kev ntsuas RDP Bond zog. Cov qauv no tuaj yeem siv rau hauv kev tshawb fawb thiab kev teeb tsa los xyuas kom meej cov kev ua tau zoo ntawm RDP hauv cov cement thiab lwm yam kev tsim kho. Siv hom qauv no tuaj yeem pab txhim kho kev tswj hwm zoo thiab kev tsim cov khoom lag luam hauv kev tsim kho kev tsim kho.
