Cov txheej txheem tsim kho
Chaw Muag Khoom Ua Si
- 1. Kev kho qhov chaw yooj yim: Tshem tawm cov hmoov av, cov roj av, cov ntsev, xeb, thiab cov tshuaj tso tawm ntawm qhov chaw los ntawm kev txhuam ua ntej thiab tom qab ntawd ntxuav. Tom qab sib tsoo kom huv si, nqus plua plav tawm.
- 2. Daim ntawv thov primer tshwj xeeb: Dov thov cov primer tshwj xeeb rau polyurea kom kaw cov qhov capillary, txo cov qhov tsis zoo ntawm cov txheej, thiab ua kom muaj kev sib txuas ntawm cov txheej polyurea thiab qhov chaw puag.
- 3. Siv cov polyurea putty los kho thiab ua kom tiaj tus ntawm cov plag tsev. Tom qab kho kom qhuav lawm, siv lub log sib tsoo hluav taws xob los xuab kom huv si thiab siv lub tshuab nqus tsev los ntxuav.
- 4. Dov cov primer tshwj xeeb rau polyurea: Rov kaw qhov chaw hauv av, ua rau qhov sib txuas ntawm polyurea thiab lub hauv paus nce ntxiv.
- 5. Tshuaj tsuag polyurea tiv thaiv dej: Tom qab sim cov tshuaj tsuag, tsuag raws li qhov kev txiav txim ntawm sab saud mus rau hauv qab thiab tom qab ntawd hauv qab, txav mus rau hauv ib cheeb tsam me me hauv tus qauv hla thiab ntev. Lub tuab ntawm txheej yog 1.5-2 hli. Kev tsuag tiav hauv ib zaug xwb. Cov txheej txheem tshwj xeeb tuaj yeem pom hauv "Polyurea Engineering Coating Specifications". Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv dej, tiv taus hnav thiab tsis plam.
- 6. Tsuag/yob cov txheej txheej tshwj xeeb rau polyurea: Sib tov cov tshuaj tseem ceeb thiab cov tshuaj kho kom zoo sib npaug, do kom huv si, thiab siv lub menyuam tshwj xeeb los dov cov txheej txheej polyurea rau ntawm qhov chaw polyurea uas kho tiav lawm. Nws tiv taus cov teeb ultraviolet, tiv thaiv kev laus thiab kev hloov xim.
Pem teb ua haujlwm
- 1. Kev kho lub hauv paus: Sib tsoo cov txheej uas ntab rau ntawm lub hauv paus, ua kom pom qhov chaw tawv. Xyuas kom lub hauv paus ncav cuag qib C25 lossis siab dua, tiaj tus thiab qhuav, tsis muaj plua plav, thiab tsis rov xuab. Yog tias muaj cov honeycomb, cov chaw ntxhib, tawg, thiab lwm yam, ces siv cov khoom kho kom kho thiab theem nws kom ntseeg tau tias ruaj khov.
- 2. Kev siv Polyurea primer: Siv cov polyurea tshwj xeeb primer sib npaug zos rau ntawm lub hauv paus kom kaw cov qhov capillary ntawm qhov chaw, txhim kho cov qauv hauv av, txo cov qhov tsis zoo hauv cov txheej tom qab txau, thiab ua kom cov polyurea putty thiab cement, hauv pem teb pob zeb lo rau lo. Tos kom txog thaum nws kho tag ua ntej mus rau kauj ruam tom ntej ntawm kev tsim kho. Yog tias muaj thaj chaw loj ntawm kev dawb tom qab thov, nws yuav tsum tau rov siv dua kom txog thaum tag nrho hauv pem teb zoo li xim av tsaus.
- 3. Kev siv Polyurea putty: Siv cov polyurea tshwj xeeb putty sib npaug zos rau ntawm lub hauv paus kom ua rau hauv pem teb tiaj tus, kaw cov qhov capillary uas tsis pom rau lub qhov muag liab qab, thiab zam qhov xwm txheej uas kev txau polyurea ua rau muaj qhov pinholes vim yog cov qhov capillary ntawm hauv pem teb. Tos kom txog thaum nws kho tag ua ntej mus rau kauj ruam tom ntej ntawm kev tsim kho.
- 4. Kev siv Polyurea primer: Rau ntawm cov polyurea putty uas tau kho lawm, thov cov polyurea primer kom sib npaug zos kom ua rau qhov sib txuas ntawm cov txheej polyurea uas tau txau thiab cov polyurea putty zoo dua.
- 5. Kev siv tshuaj tsuag polyurea: Hauv 24 teev tom qab cov primer kho, siv cov cuab yeej txau tshuaj kom txau polyurea sib npaug. Qhov saum npoo ntawm cov txheej yuav tsum du, tsis muaj dej ntws tawm, qhov, npuas, lossis tawg; rau cov kev puas tsuaj hauv zos lossis qhov, kev kho polyurea tes siv tau.
- 6. Daim ntawv thov Polyurea topcoat: Tom qab polyurea nto qhuav, thov polyurea topcoat kom tiv thaiv kev laus, kev hloov pauv, thiab txhim kho kev hnav tsis kam ntawm polyurea txheej, tiv thaiv polyurea txheej.
Cov khoom siv khawb av
- 1. Cov hlau substrate, xuab zeb rau kev tshem tawm xeb ncav cuag SA2.5 tus qauv. Qhov saum npoo tsis muaj plua plav paug, roj av, thiab lwm yam. Kev kho sib txawv yog ua raws li lub hauv paus.
- 2. Tshuaj tsuag primer (txhawm rau txhim kho qhov lo ntawm polyurea rau lub hauv paus).
- 3. Kev siv tshuaj tsuag Polyurea (txheej tiv thaiv tseem ceeb. Feem ntau pom zoo kom tuab li ntawm 2 hli thiab 5 hli. Cov phiaj xwm tsim kho tshwj xeeb tau muab raws li cov khoom sib xws).
- 4. Kev siv txhuam/txaus xim rau sab saum toj (tiv thaiv kev daj, tiv taus UV, ua rau ntau yam xim xav tau).
