Qhov kub ntawm cov khoom siv ℃ 5-10 15-20 25-30
Lub sijhawm luv dua h48, 24, 12
Lub sijhawm ntev tshaj plaws tsis pub tshaj 7 hnub. - Qhov kub ntawm lub substrate yuav tsum siab dua qhov dew point ntawm ntau dua 3 ℃, thaum qhov kub ntawm lub substrate qis dua 5 ℃, cov xim zaj duab xis tsis kho, thiab yuav tsum tsis txhob tsim.
Kev tsim kho pleev xim
- Tom qab qhib lub thoob ntawm cov khoom A, nws yuav tsum tau do kom zoo, thiab tom qab ntawd ncuav pawg B rau hauv cov khoom A hauv qab do raws li qhov yuav tsum tau ua, sib tov kom zoo thiab cia nws loj hlob rau 30 feeb, tom qab ntawd ntxiv cov thinner kom tsim nyog thiab kho nws rau qhov viscosity ntawm kev tsim kho.
- Diluent: diluent tshwj xeeb rau polyurethane series.
- Kev txau tsis siv cua: Tus nqi dilution yog 0-5% (los ntawm qhov hnyav piv ntawm cov xim), lub nozzle calibre yog 0.4mm-0.5mm, kev txau siab yog 20MPa-25MPa (200kg / cm²-250kg / cm²).
- Kev txau cua: Tus nqi dilution yog 10-15% (los ntawm qhov hnyav piv ntawm cov xim), lub nozzle calibre yog 1.5mm-2.0mm, kev txau siab yog 0.3MPa-0.4MPa (3kg / cm²-4kg / cm²).
- Txheej txheej rau cov menyuam: Tus nqi dilution yog 5-10% (nyob rau hauv cov nqe lus ntawm qhov hnyav xim piv).
Cov kev ceev faj
- Thaum lub caij kub siab, yooj yim rau cov tshuaj tsuag qhuav, kom tsis txhob muaj cov tshuaj tsuag qhuav tuaj yeem hloov kho nrog cov tshuaj thinner kom txog thaum tsis qhuav tshuaj tsuag.
