Kev piav qhia txog khoom
Cov txheej Polyurea feem ntau yog tsim los ntawm cov khoom isocyanate thiab polyether amines. Cov khoom siv raw tam sim no rau polyurea feem ntau yog MDI, polyether polyols, polyether polyamines, amine saw extenders, ntau yam khoom siv ntxiv, pigments thiab fillers, thiab cov diluents nquag. Cov txheej Polyurea muaj cov yam ntxwv ntawm kev kho sai, kev tsim kho sai, kev ua haujlwm zoo tiv thaiv corrosion thiab dej tsis nkag, ntau qhov kub thiab txias, thiab cov txheej txheem yooj yim. Lawv yog qhov tsim nyog rau ntau yam kev lag luam thiab kev lag luam tsuas, chaw nres tsheb, chaw ua si nawv, thiab lwm yam, rau kev txheej hauv pem teb nrog cov kev cai rau kev tiv thaiv kev plam, tiv thaiv corrosion thiab hnav tsis kam.
COV NTAUB NTAWV KHOOM
- Kev hnav tsis kam zoo, khawb-resistant, kev pab cuam lub neej ntev dua;
- Nws muaj zog dua li epoxy pem teb, tsis muaj tev tawm lossis tawg:
- Qhov coefficient ntawm kev sib txhuam ntawm qhov chaw yog siab, ua rau nws tsis yooj yim plam dua li epoxy pem teb.
- Ib txheej txheej zaj duab xis tsim, qhuav sai, yooj yim thiab ceev ceev tsim kho:
- Kev pleev xim dua tshiab muaj kev nplaum zoo heev thiab yooj yim kho.
- Koj xaiv tau xim tau yooj yim. Nws zoo nkauj thiab kaj. Nws tsis muaj tshuaj lom thiab zoo rau ib puag ncig.
Cov txheej txheem tsim kho
Kev tiv thaiv dej ntawm lub ru tsev
Lub ru tsev tiaj tiaj [Kev tiv thaiv dej tsis pub nkag rau cov chaw sawv kev ua si]
Cov txheej txheem tsim kho lub ru tsev nqes hav, lub hauv paus pobzeb
- 1. Ntxuav cov hmoov av, kho qhov chaw hauv qab kom huv si thiab huv si. Yog tias muaj cov vuas uas raug tsa, txav lossis puas lawm, lawv yuav tsum tau hloov chaw. Cov vuas tawg thiab cov chaw uas muaj qhov sib txawv loj yuav tsum tau kho nrog plastering kom cov vuas ruaj khov thiab tsis xoob, thiab ua tau raws li cov xwm txheej ntawm kev tsim kho.
- 2. Siv cov kev ntsuas tiv thaiv, siv cov hnab yas los tiv thaiv cov khoom ntawm lub ru tsev thiab ib puag ncig, xws li lub qhov rais saum ru tsev, cov xov hlau, cov vaj huam sib luag hnub ci, tsheb, thiab lwm yam.
- 3. Dov/siv cov primer tshwj xeeb rau polyurea los kaw cov qhov hws ntawm lub hauv paus, ua rau lub zog sib txuas ntawm cov txheej txheem nce ntxiv.
- 4. Tsuag cov khoom siv polyurea elastomer waterproof ua txheej tseem ceeb, tsom mus rau kev tswj cov ntsiab lus xws li lub ntug, cov vuas sab, cov ces kaum, cov kwj dej, cov parapets, thiab lwm yam.
- 5. Dov/siv cov txheej txheem tshwj xeeb rau polyurea, ua rau nws zoo nkauj, tiv taus huab cua, thiab tsis hloov xim.
Chaw Ua Si Dej
- 1. Kev kho yooj yim: Tshem tawm cov txheej slurry hauv paus thiab nthuav tawm qhov chaw tawv. Xyuas kom meej tias lub hauv paus ncav cuag qib C25 lossis siab dua, tiaj tus thiab qhuav, tsis muaj plua plav, thiab tsis rov xuab zeb. Yog tias muaj honeycombs, qhov 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 tom qab txau, thiab ua kom cov polyurea putty thiab cement, av pob zeb lo rau. Tos kom txog thaum nws kho tag ua ntej mus rau kauj ruam tom ntej. Yog tias muaj kev dawb ntau tom qab siv, nws yuav tsum tau rov siv dua kom txog thaum tag nrho cov av 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 av tiaj tus, kaw cov qhov capillary uas tsis pom rau lub qhov muag liab qab, thiab zam qhov xwm txheej uas cov polyurea txau muaj cov qhov pinholes vim yog cov qhov capillary hauv av. Tos kom txog thaum nws kho tag ua ntej mus rau kauj ruam tom ntej.
- 4. Daim ntawv thov Polyurea primer: Siv cov polyurea primer sib npaug zos rau ntawm cov polyurea putty uas tau kho kom zoo kom ua rau qhov sib txuas ntawm cov txheej polyurea uas tau txau thiab cov polyurea putty zoo dua.
- 5. Siv tshuaj tsuag polyurea: Hauv 24 teev tom qab cov primer kho, siv cov cuab yeej txau tshuaj kom txau polyurea sib npaug. Qhov chaw pleev xim yuav tsum du, tsis muaj dej ntws, qhov, npuas, lossis tawg; rau qhov puas tsuaj hauv zos lossis qhov, siv tau kev kho polyurea tes.
- 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.
