Cov hmoov polymer uas yaj tau dua (RDP) yog cov hmoov polymer emulsion uas yaj tau hauv dej. Cov khoom siv no siv dav hauv kev lag luam kev tsim kho, feem ntau yog cov khoom sib txuas rau cov cement thiab lwm yam khoom siv hauv tsev. Lub zog sib txuas ntawm RDP yog qhov tseem ceeb rau nws daim ntawv thov vim nws cuam tshuam ncaj qha rau cov khoom ntawm cov khoom kawg. Yog li ntawd, nws yog ib qho tseem ceeb kom muaj txoj kev sim raug thiab txhim khu kev qha los ntsuas lub zog sib txuas ntawm RDP.
Cov Txheej Txheem Xeem
Khoom siv
Cov ntaub ntawv uas yuav tsum tau siv los ua qhov kev xeem no yog raws li nram no:
1. Piv txwv RDP
2. Cov khoom siv xuab zeb xuab zeb
3. Cov ntawv impregnated resin (300um tuab)
4. Cov nplaum uas ua los ntawm dej
5. Lub tshuab kuaj tensile
6. Vernier caliper
kev sim tshuaj
1. Kev npaj cov qauv RDP: Cov qauv RDP yuav tsum tau npaj nrog cov dej kom txaus raws li tus neeg tsim khoom tau teev tseg. Cov qauv yuav tsum tau npaj raws li cov kev cai ntawm daim ntawv thov.
2. Kev npaj cov khoom siv: Cov khoom siv txhuas tom qab xuab zeb yuav tsum tau ntxuav thiab ziab ua ntej siv. Tom qab ntxuav, qhov roughness ntawm qhov chaw yuav tsum tau ntsuas nrog lub vernier caliper.
3. Kev siv RDP: RDP yuav tsum tau siv rau ntawm lub substrate raws li cov lus qhia ntawm cov chaw tsim khoom. Qhov tuab ntawm zaj duab xis yuav tsum tau ntsuas siv lub vernier caliper.
4. Kev Kho Kom Qhuav: RDP yuav tsum qhuav hauv lub sijhawm uas tus neeg tsim khoom teev tseg. Lub sijhawm qhuav yuav txawv nyob ntawm hom RDP siv.
5. Kev siv daim ntawv uas muaj cov roj hmab mos mos: Daim ntawv uas muaj cov roj hmab mos mos yuav tsum txiav ua tej daim me me thiab zoo li daim duab. Daim ntawv yuav tsum tau muab nplaum dej rau kom sib npaug.
6. Kev nplaum cov ntawv nplaum: Cov ntawv nplaum uas muaj txheej nplaum yuav tsum muab tso rau ntawm RDP coated substrate. Yuav tsum nias me ntsis kom paub tseeb tias sib txuas zoo.
7. Kev Kho Kom Qhuav: Cov nplaum yuav tsum qhuav hauv lub sijhawm uas tus neeg tsim khoom teev tseg.
8. Kev sim tensile: Muab cov qauv tso rau hauv lub tshuab sim tensile. Lub zog tensile yuav tsum tau sau tseg.
9. Kev Xam: Lub zog sib txuas ntawm RDP yuav tsum tau xam raws li lub zog uas xav tau los cais cov RDP coated substrate ntawm daim kab xev ntawv faib los ntawm thaj chaw ntawm RDP coated substrate.
xaus lus
Txoj kev sim no yog ib txoj kev yooj yim thiab pheej yig los ntsuas lub zog ntawm RDP. Txoj kev no siv tau rau hauv kev tshawb fawb thiab kev lag luam kom ntseeg tau tias RDP ua haujlwm tau zoo tshaj plaws hauv cov cement thiab lwm yam khoom siv hauv kev tsim kho. Kev siv txoj kev no tuaj yeem pab txhim kho kev tswj hwm zoo thiab kev tsim khoom hauv kev lag luam tsim kho.
