Below be some development data of the magnesium ecological plate that makes of the production technique of magnesium ecological plate provided by the invention:
Table 1 nonmetallic metal powder of scrap circuit boards analysis of components
| Sequence number | The composition title | Content % |
| 1 | Phenol-formaldehyde resin | 56 |
| 2 | Resins, epoxy | 8.5 |
| 3 | Glass fibre | 35 |
| 4 | Softening agent etc. | 0.5 |
| Add up to | 100 |
Analysis of components shows, wooden chaff in the large and glass magnesium plate of organism in the nonmetallic metal powder of scrap circuit boards end (resin that has solidified) proportion is similar, in combustionproperty, be combustible material, but the size of other performances such as particle, shrinkability, the wooden chaff of water tolerance are stable.The earthfill rockfill concrete riprap RCC of the character of other inorganic componentss and existing production glass fibre and magnesium cement board seemingly in the powder.
The nonmetallic metal powder of scrap circuit boards end is the particle that carries out reciprocating gird with water behind the crusher in crushing wiring board, the open-air product of placing of non-processor after pulling out in the deposition pond.Water content (evaporated water) to the nonmetallic metal powder of scrap circuit boards end of different batches is tested, and probe temperature is 65 ℃ ± 1 ℃, has found the ununiformity of water content in nonmetallic metal powder of scrap circuit boards.
The moisture performance index of table 2
Annotate: moisture definition of quantity: under a certain probe temperature, sample carries out drying and processing, and the quality (m1) before the sample pretreating deducts the quality (m2) behind the sample pretreating, divided by the quality behind the sample pretreating (m2), multiply by per-cent and is the sample water ratio.Calculating formula is m1-m2/m2 * 100%.
Find simultaneously following situation in process of the test:
In the process that stores that do not coexist of water content, different caking phenomenons has appearred.
Water content is lower than 20% particle, is easy to stir and disperse in the process that stirs.
Water content is higher than 20% particle, is easy to occur material group and material piece in the process that stirs.
Therefore must adopt the mode that mechanical continuous drying sieves to the processing of moisture or manually dry the mode of sieving and carry out, to reach the more consistent nonmetallic metal powder of scrap circuit boards end of water content requirement.Following table is through the powder water ratio behind the drying and processing.
Table 3 moisture performance index after treatment
The data that moisture content is processed show: the nonmetallic metal powder of scrap circuit boards end can be as applying filler in magnesium gelatinous material through after adopting rational moisture content processing mode.And the mode that moisture content is processed adopts continuous mechanical furnace drying method more manually to shine and makes a good job of.
The power applications experiment of different moisture content
Table 5: the process phenomenon table during the different moisture content power applications
Test-results shows: the water content of powder is less than or equal to 18% the time, and result of use is comparatively desirable.
Screening, the classification of nonmetallic metal powder of scrap circuit boards end particle diameter: the nonmetallic metal powder of scrap circuit boards end is to process without size classification just directly to abandon so contain different size-grade distribution after the crushing mechanism fragmentation.Different particle diameter size of powder particles has affected the use in magnesium gelatinous material.The finished product thickness of magnesium gelatinous material also has certain requirement to filler, then requires the particle diameter of wooden chaff should be less than 2mm such as the 3mm plate.According to the test block in a series of laboratory experiment, shown in magnesium gelatinous material the granularity requirements to the broken powder of old circuit board.
Table 6: particle filter experimental result
According to comprehensive physical performance and the appearance requirement to the observation of process of the test and trial-production finished product, there is concrete granularity requirements at the nonmetallic metal powder of scrap circuit boards end of using as stopping composition: during thickness≤4mm, the powder that uses 20 mesh sieve all-pass to cross, during 6mm≤thickness≤10mm, the powder that uses 10 order all-pass to cross is comparatively desirable.Data declaration selects the thinner powder of granularity better, but has increased simultaneously the energy consumption of the each side such as oven dry.
The test of incorporation: the adding of doping level is the key that affects product performance.Desirable doping level is The more the better during practical application, considers the over-all properties of product, should control the doping level at nonmetallic metal powder of scrap circuit boards end.Utilize the nonmetallic metal powder of scrap circuit boards end as the stopping composition of glass fibre and magnesium cement board, because and original wood sawdust stopping composition is from there being in essence many differences, particularly the difference of water-absorbent and toughness is particularly outstanding, for these different differences, it is crucial formulating scientific and reasonable mix proportion scheme, the intensity that affects at most product is rigid, affects at least toughness and the set time of product.And combustionproperty is especially as one of key property of glass magnesium plate, and it is important that stopping composition has play a part in product, and a large amount of comparative tests have been done by research and development centre, have finally determined the science consumption of powder.
The sheet material folding strength test of table 7 different sorts stopping composition
Table 8 doping level is on the impact of combustionproperty
Can find out from table 7 and table 8: when incorporation was controlled between the magnesian 40%--50%, the combustionproperty of magnesium ecological plate still can meet the product standard requirement; The bending strength of mixing the sheet material at nonmetallic metal powder of scrap circuit boards end slightly is better than the sheet material with other kind fillers.
The test of the different doping level different sorts of table 9 fillers affect sheet material water ratio
Test-results shows: be filler with nonmetallic metal powder of scrap circuit boards, along with the increase of doping level, the impact of sheet material water ratio is also little, is filler with wooden chaff, and the water ratio of sheet material increases with doping level.Simultaneously process of the test is found: the amount ratio of mixing the nonmetallic metal powder of scrap circuit boards end mixes wooden chaff or perlitic amount has exceeded 3 times to 5 times.
Magnesium ecological plate not only has the properties of national standard glass fibre and magnesium cement board, and product has passed through the test (seeing examination and test of products report) of national correlation department.Not only environmental protection of this product, nontoxic, harmless, but also have fire prevention, moistureproof and anti-water function.
