Tej yaam num

1. Kev tua blasting thiab xeb tshem tawm yuav tsum tau nqa tawm ntawm cov khoom siv hlau ua ntej pleev xim.Los ntawm txhais tes mechanical xeb tshem tawm tuaj yeem siv rau kev kho hauv zos.Qib tshem tawm xeb yuav tsum mus txog qib Sa2 2/1 thiab St3.

Qhov chaw kho steel yuav tsum tsis muaj vuam slag, vuam caws pliav, plua plav, roj, dej thiab burrs.

2. Tag nrho cov khoom siv hlau yuav tsum tau txau nrog primer ua ntej tawm hauv lub hoobkas;Lub sij hawm ncua sij hawm los ntawm kev ua tiav ntawm kev tshem tawm xeb ntawm cov khoom mus rau cov tshuaj tsuag ntawm primer yuav tsum tsis txhob tshaj "Code".

3. Qhov tshwj xeeb primer ib feem thiab cov primer puas thaum lub sij hawm kev thauj mus los thiab installation yuav tsum tau polished los ntawm txhais tes los ua lub thickness ntawm primer.

4. Rau qhov chaw vuam ntawm qhov chaw, cov vuam slag yuav tsum tau muab tshem tawm thiab polished ua ntej pleev xim.Cov txheej yog tib yam li ntawm lub cev tseem ceeb.

5. Txheej txheej yuav tsum tau ua rau cov khoom steel: dej-raws li inorganic zinc-nplua nuj primer, thickness 2x40um;intermediate xim, thickness 2x25um;polyurethane topcoat (rau siv sab hauv tsev) 2x20um.

6. Nyob rau hauv qhov project no, rau lub ntsiab structural ib feem ntawm lub ru tsev steel qauv, qhov ntsuas hluav taws kub tsis tsawg tshaj li 1.5 teev;rau cov hlau purlins thiab lub ru tsev, qhov ntsuas hluav taws xob tsis pub tsawg tshaj 1.0 teev.

7. Cov khoom siv hluav taws xob uas tau xaiv hauv qhov project yuav tsum muaj daim ntawv tshaj tawm kev xeem thiab daim ntawv tso cai tsim khoom tau pom zoo los ntawm lub koom haum kuaj lub teb chaws rau nws qhov kev ua tau zoo ntawm cov hluav taws kub.

8. Txhua qhov hluav taws kub retardant coatings yuav tsum xyuas kom zoo compatibility, adhesion thiab hluav taws tsis kam nrog primers, intermediate xim los yog topcoats;
