The plank of the force that press a gram on home market applies in what carve an industry, come nearly two years homebred the force that press a gram (organic glass) plank because quality stabler, price is more reasonable, already got domestic sculpture industry is approbated, market sales volume jumps. But at present retail price 15 yuan / the plank of the force that press a gram under Kg is 2 entirely reclaim makings mould and into, function cannot reach national level. Expect treatment production investment is small 2 times, basic it is production of small mill type, scope is little, equipment is pallet, no matter the exterior is immanent still,so character cannot is likened to with virgin material product. But because the price is low, market growth is swift and violent, the product demands exceeds supply, when organic glass manufacturer is seeking yield unwary quality standard, product quality problem is constant, if board area size is insufficient, ply common difference is big, board face has dirt and drossy thing, board face has nick, bleb to wait apparently; Some businessmen with 11 yuan / kilogram right-and-left low is sold in the market, actual be go up in ply more make an issue of...One, level of state of plank of as organic as the virgin material that sculpture industry concerns glass (GB7134-86) have:
1, standard public errand: With plank width of cloth 1 × 1.3m is a standard, be more than this width of cloth allow to increase accordingly.
One class tastes: <5mm: 5mm of ≥ of of ± 12%-20% : ± 10%
Seconds: <10mm: 10mm of ± 12%-40% ≥ : ± 10%
2, be out of shape temperature: 75 ℃----84 ℃
3, standard proportion: 1.19 ± 0.02
2, the note that machines processing:
1, reworked material is easier than virgin material plank dissolve at organic dissolvent, crackle of silk of Qi Changchang occurrence silver is filled after causing sculpture, solve method to have commonly below 3 kinds of methods:
A chooses propylene kind painty (colophony kind) general art store can be bought.
B chooses amino paint, generalization is versed in inn can be bought.
After C fills lacquer again polishing processing.
2, to organic glass surface the loss with a few slight not quite apparent perhaps cut is handled, use sand paper wet burnish commonly, when burnish sand paper wants annular shift, of sand paper fineness should add gradually arrive high 600 eye above, can use toothpaste to brush finally grind can.
3, plank has electrostatic when easy adherent dirt, chamois should be used before silk imprints or filling lacquer or be stained with the soft cloth wipe up of 1% suds, in order to achieve clean result.
3, board area size and real weight
Because be miniature primitive treatment, manufacturer aborning is to use pattern plate mould, increase as the ply of organic glass plank for expecting glue is in charge of and increase, took up more plank spaces, the thickness of organic glass plate that so mould of identical pattern plate comes out is thicker, the size of finished product plank is smaller. But manufacturer consolidates the measure that writes pattern plate only when writing detailed account, is not each ply the specific measure of organic glass plank, there is an error to appear on the norms of the product, because this manufacturer is used entirely,call serious means settle accounts. If answer the weight that says to be offerred with manufacturer differs ± 0.3kg regards as reasonable. But in the everybody in the sale to go to the lavatory, basically be with theory computation is given priority to, formula of simple and easy computation is: Actual length (rice) × actual width (rice) × actual ply (millimeter) × proportion (1.2) = kilogram several. Academic calculative weight and the error that say to weigh want special attention in board of larger the force that press a gram, the board face of 15 millimeter above measures general thickness should calculate millimeter, ability makes sure weight is unapt with had differred actually big.
