Cov nplaum kub yaj rau lub teeb tsheb WD8560B
WD8560B yog ib qho khoom siv polyurethane kub yaj nplaum, uas yog ib qho khoom khov kho ntawm chav tsev kub, ua kua tom qab cua sov, thiab tsim cov khoom sib txuas ua ntej tom qab txheej thiab sib txuas. Tom qab ntawd nws muaj kev sib txuas zoo heev, tiv taus kub, tiv taus dej, tiv taus roj, thiab tiv taus kev laus vim nws muaj peev xwm kho nrog huab cua thiab dej noo ntawm qhov chaw ntawm cov khoom sib txuas.
Cov khoom no ua raws li cov qauv teev tseg hauv GB33372-2020 Cov Kev Txwv ntawm Cov Khoom Siv Organic Volatile hauv Cov Nplaum.
Siv rau hauv cov khoom siv sab hauv tsheb thiab teeb liab, nws muaj cov khoom sib txuas zoo rau cov ntaub ntawv xws li PVC, ABS, PMMA, PP, thiab lwm yam tom qab kev kho mob corona.
1. Ib qho khoom, yooj yim rau kev tswj hwm, tsim nyog rau kev ua haujlwm kho tshuab, ua haujlwm tau zoo.
2. Cov ntsiab lus ntawm 100%, tsis muaj kuab paug, tus phooj ywg ib puag ncig.
3. Lub sijhawm qhib luv luv thiab qhov ceev ceev.
1. Qhov chaw sib txuas yuav tsum khaws cia kom qhuav, huv si, thiab tsis muaj roj av, thiab yuav tsum tau txhuam kom zoo.
2. Rau cov ntaub ntawv qis polarity xws li PP, corona / nplaim taws kev kho mob yog qhov yuav tsum tau ua kom ntseeg tau tias dielectric tas li ntawm 34 lossis siab dua.
3. Thaum siv, qhov kub ntawm qhov chaw ntawm cov khoom uas lo rau yuav tsum tsis txhob qis dua 20 ℃. Yog tias tsim nyog los khi cov khoom, nws yuav tsum tau ua kom sov.
4. Siv lub kaw lus PUR kua nplaum uas kaw lawm rau kev yaj kua nplaum, thov siv cov kua nplaum uas yaj sai li sai tau.
5. Siv lub tshuab nplaum PUR tshwj xeeb, cov nplaum raug siv los ntawm kev dov, khawb, txau, thiab lwm txoj kev.
6. Cov kua nplaum uas yaj thiab cov kua nplaum uas xau rau hauv huab cua yuav tsum siv kom tag hauv 2-3 teev li ntau tau.
7. Qhov chaw zoo tshaj plaws rau kev kho yog qhov kub ntawm 25 ℃ thiab av noo ntawm 50% lossis siab dua.
8. Siv cov tshuaj ntxuav tshwj xeeb PUR rau kev ntxuav.
1. Yuav tsum tau nruab cov khoom siv tso pa tawm hauv zos hauv thaj chaw ua haujlwm kom ntseeg tau tias muaj cua nkag.
2. Thaum siv, nws yog ib qho tsim nyog yuav tsum hnav khaub ncaws ua haujlwm, hnab looj tes paj rwb, lub ntsej muag tiv thaiv, tsom iav thiab lwm yam khoom siv tiv thaiv tus kheej.
3. Cov khoom yuav khov vim yog dej noo, yog li ntawd yuav tsum tau kuaj xyuas qhov ntim khoom ua ntej siv kom paub tseeb tias cov khoom raug kaw kom zoo.
4. Tsis txhob sib tov cov khoom nrog lwm cov qib ntawm cov nplaum kub yaj.
5. Thov nyeem phau ntawv qhia txog kev nyab xeeb ntawm cov khoom ua ntej siv.
