Tell you how to Recognize the real imported dynea brown film or chinese domestic brown film ?
Yesterday visited one of the biggest film faced plywood factory ,the sales director told us his experience on how to recognize Tell you how to Recognize the real imported dynea brown film or chinese domestic brown film ,I think this is good lesson ,sure he is professional on the film used for ffp .
We discussed three of the major difference :
1.the imported film has dark and uniform color from its appearance
2.the printed letters or logos printed on the imported film is not clear ,sometime we can say its fade color or not clear.The domestic film has good printing with clear letters or golden color .
3.I compared the samples with their company logo and another Pizhou’s biggest factory ‘s ffp ,found they are real the same good film .
also found they have one really modern ffp hot pressing machine ,told me only one machine in CHINA .make sure that the temperature and pressing rate are all uniform for each layer of the hot pressing plate ,so that the film of the ffp has no burn marks and pressing ratio are the uniform and same without potential risks .
Why The film of the ffp has come off?
Met one serious problem,many film of the film faced plywood has come off ,I don’t know what happened ,the quality of the film or the plywood platform problems or hot pressing problems ?
We have no idea yet,will check and study .
WBP Glue 11 Layers eucalyptus hardwood+2 layers poplar +2 black film ,Three steps production film faced plywood.\
We used exterior glue ,passed 72 hours boiling test ,calibrated two times ,three times hot pressing ….
Visited many factories these days,looks the middle east markets are still much better than other countries .
Still huge quantity of film faced plywood with joint recycled cheap prices film faced plywood to middle east countries ,more joint core one time hot press without sanding ,also more two-step production process joint core ffp .
they buy the cheapest joint core ,not sure what these plywood will be used for ?but sure the quality is low too many burn marks and also some broken plywood ,film surface is urgly …
i saw one factory is producing full 3 layers ecualyptus hardwood core +10 layers poplar veneer core ,plus the 2 film ,total 15 plies .the price is fob lianyungang 12***rmb/pcs ,exterior glue .support you buy full hardwood high quality plywood from China,not the cheapest one ,not the lowest quality one .
HOW TO RECOGNIZE THE QUALITY OF THE FILM OF THE FFP ?
1.check the glue types of the film ?melamine ,MR.wbp ,phenolic WBP ?or mixed ?
2.check how much quantity of the glue for per square meter ?
3,use the fire lighter to burn the film ?
4.gram of the film ?weight ?
5.any white spot of the film ?
6.the valid time of the film ?one month or two month ,how to stock and keep the film in good condition ?
4.0MM / 6.0MM/9.0MM DYNEA BROWN FILM FACED PLYWOOD TO EUROPE WITH FORMALDEHYDE EMISSION E1 AND ALSO THE FILM IS ALSO E1 GLUE ?
cool,saw the excellent film faced plywood today ,thin film faced plywood .
everybody know the thinner film faced plywood the more difficulity to produce because of the the bubble and break .
i saw one factory today ,really excellent european standard grade film faced plywood with formaldehyde emission E1 and also the film is also E1 glue .
The film of film faced plywood appointed for regular film faced plywood suppliers is good or not ?
More and more buyers have been trying to appoint the film of the film faced plywood for their purchase orders ,is this way good for your production or not to keep good quality ?
Some people said this is good as appoint one film factory can give stable and uniform color and quality film .
Some people said are not good ,as this will increase the cost of the film buying prices for the factories even to buy the same quality film from other un-appointed film .
We can discuss ……
Thick Water-Resistant paint of the film faced plywood ?Have you paid 100% on the edges ?All cut edges and tie-bolt holes are sealed with 2 coats of a water resistant paint.
Film faced surface of the panel prevents it from moisture penetrating, has high resistance to abrasion, chemicals and fungus formation. Edges of film-faced plywood are varnished with water-resistant acryl-based paint.
Edges of panels are sealed at the mill with special paint to protect them against moisture absorption. All machinings that break the film face and all edges sawn on site must also be treated with sealing paint or filler. We recommend a minimum fo two layers de paint to be used.
CONCRETE FORM PLYWOOD – FILM FACED PLYWOOD
The overlay is a phenolic, resin-impregnated cellulose fibre sheet, which is bonded to the face of a plywood panel under high heat and pressure, forming a hard, durable and smooth surface. Providing enhanced resistance to the high pressure and wet service conditions of concrete construction, overlaid plywood is used primarily for concrete forming in high-rise and residential construction, sports complexes and highway infrastructure.
Overlaid panels provide a smoother concrete surface and more re-uses than standard panels. Re-use potential and fineness of concrete finish increase with the density of the overlay. These panel products are designed to provide exceptional strength, rigidity and dimensional stability with maximum re-use and superior finish.
Thickness: Thickness ranges from 9.5mm to 35.0mm, overlaid on one or both sides.
Panel Size: Standard size is 4’x8’ (1220x2440mm). Customized sizes are 4’x9’ (1220x2745mm), 4’x10’ (1220x3050mm) and 5’x10’ (1525x3050mm).
