Polyurethane hmoov txheej
Kev Taw Qhia General:
Cov hmoov coatings ua los ntawm hydroxyl polyester resin, nrog rau cov tshuaj zoo heev, thiab zoo nkauj heev, theem, tshuaj tsis haum, huab cua tsis kam thiab muaj zog roj.Nws yog haum rau cov hlau zoo li txheej ntawm tsheb kauj vab, tsheb, maus taus, refueling tshuab thiab kev ua liaj ua teb machinery nrog siab yuav tsum tau ntawm cov tshuaj tiv thaiv thiab roj kuj.
Khoom Series:
muab cov ntsiab lus tseem ceeb (80% saum toj no), semi-light (50-80%), iav dawb (20-50%) thiab tsis muaj teeb (20% hauv qab) cov khoom lossis raws li qhov yuav tsum tau ua
Lub cev muaj zog:
Lub ntiajteb txawj nqus (g / cm3, 25 ℃): 1.4-1.7
Particle loj faib: 100% tsawg dua 100 micron (Nws tuaj yeem hloov kho raws li qhov tshwj xeeb ntawm txheej txheej)
Kev tsim kho:
Pretreatment: sib txawv pretreatment rau sib txawv substrates (phosphating kev kho mob, suab nrov txau kev kho mob, txhaj tshuaj peening kev kho mob)
Curing hom: phau ntawv los yog siv rab phom tsis siv neeg zoo li qub
Curing tej yam kev mob: 200 ℃ (workpiece kub), 10 feeb
Txheej kev ua tau zoo:
| Cov khoom kuaj | Kev soj ntsuam tus qauv lossis txoj kev | Ntsuas ntsuas |
| cuam tshuam tsis kam | ISO 6272 Kev Tswj Xyuas | 50 kq cm |
| khob test | ISO 1520 Kev Tswj Xyuas | 8mm ib |

| kub tsis kam | 150 ℃ / 24 teev (dawb) | zoo heev lub teeb tuav, xim txawv≤0.3-0.4 |
Nco tseg:
1.Cov kev ntsuam xyuas saum toj no siv 0.8mm tuab txias-kuav los tiag steel daim hlau nrog cov txheej thickness ntawm 50-70 microns.
2.Qhov kev ua tau zoo ntawm cov txheej saum toj no tuaj yeem hloov nrog kev hloov xim thiab gloss.
Kev pab them nqi nruab nrab:
9-11 sq.m./kg;zaj duab xis thickness 60 microns (xws li 100% hmoov txheej siv tus nqi)
Packing thiab thauj:
cartons yog lined nrog polyethylene hnab, nqa nyhav yog 20kg;Cov ntaub ntawv tsis muaj kev phom sij tuaj yeem thauj tau ntau txoj hauv kev, tab sis tsuas yog kom tsis txhob raug tshav ntuj ncaj qha, ya raws thiab cua sov, thiab tsis txhob sib cuag nrog cov tshuaj lom neeg.
Kev Cia Siab:
Ntxuav, qhuav, ventilated, deb ntawm lub teeb, chav tsev kub hauv qab no 30 ℃, thiab yuav tsum tau insulated los ntawm hluav taws qhov chaw, deb ntawm tshav kub qhov chaw. Lub sij hawm cia zoo yog 12 lub hlis txij li hnub tsim khoom.Tsis txhob tso ntau tshaj 4 txheej.
Nco tseg:
Tag nrho cov hmoov ua rau lub cev ua pa, yog li zam kom tsis txhob nqus cov hmoov thiab chav los ntawm kev kho.Sim kom tsis txhob sib cuag ncaj qha ntawm daim tawv nqaij thiab hmoov txheej.Ntxuav daim tawv nqaij nrog dej thiab xab npum thaum xav tau kev sib cuag.Yog tias qhov muag tshwm sim, ntxuav daim tawv nqaij tam sim nrog dej huv thiab nrhiav kev kho mob tam sim ntawd.Plua plav txheej thiab hmoov particle deposition yuav tsum tau zam ntawm qhov chaw thiab cov ces kaum tuag.Cov khoom me me ntawm cov organic yuav ignite thiab ua rau tawg nyob rau hauv hluav taws xob zoo li qub.Tag nrho cov khoom siv yuav tsum tau ua hauv av, thiab cov neeg ua haujlwm tsim kho yuav tsum hnav cov khau tiv thaiv zoo li qub kom cov av tiv thaiv hluav taws xob zoo li qub.
