Description
Technical field
The invention belongs to Environmental-protecting treater field, particularly a kind of nano-photocatalyst wood-based plate processing equipment control system
System.
Background technology
It is best to use not containing or contain less the adhesive of formaldehyde components in the production process of wood-based plate, have at present
This harmless or low evil adhesive comes out, but because cost is too high, there is no method to promote the use of.Due to catalure
Have the advantages that low cost, performance are high, at present by countries in the world in a large number using in the manufacturing process of wood-based plate.This artificial
In board production technology, the general layout with catalure as leading position also is difficult to change in foreseeable future.And ureaformaldehyde
Resinae adhesive is rich in formaldehyde components, can discharge the formaldehyde gases highly unwanted to human body for a long time, cause serious public hazards.As
Where reduce its content of formaldehyde before wood-based plate flow into the market places thus effectively reduce use during the burst size of formaldehyde be
One technical barrier urgently to be resolved hurrily.
Mainly this above-mentioned technical problem is solved using following several method at present：
Facing method：Stick on the crust stoping gas penetration in finished synthetic's plate outer surface.This method is made at present in a large number
With.Although the method can stop the harmful gass in artificial plate and its product to discharge to a certain extent.But one
Denier facing crust is damaged, and harmful gass will be overflowed in a large number.Therefore it is not a kind of method of basic improvement.
Chemical treatment:Spray chemical reagent in artificial plate surface or surrounding air, it is harmful that neutralization sheet material discharges
Gas.Although this method can reduce the hazardness of the harmful gass such as formaldehyde to a certain extent, only a kind of short-term
Effect, the chemical reagent simultaneously being used often causes new pollution.
Physical treatment：Try every means and make the harmful gass in artificial board or its product concentrate discharge, to reach fall
The purpose of low sheet material formaldehyde emissions rate in follow-up use.Have pointed out at present or the physical treatment method of use has：
A, hot ammonia facture (from Belgium, Holland)：The hot ammonia recycle for 50-55 DEG C for the temperature is imported and is placed with
In the confined space of wood-based plate, make ammonia penetrate into sheet material internal or with heating after the formaldehyde that evaporates react and generates innocuous substance
(hexamethylenetetramine).Because the infiltration of ammonia is an extremely slow process, therefore processing procedure not only take, consumptive material (ammonia),
Consumption to energy is also very big.The process that the method processes sheet material is very slow, and required time is about 10-24 depending on the difference of sheet material
Hour.
Due to the treatment effeciency of this method too low it is thus proposed that improvement project.Its basic ideas is：In wood-based plate
Side forms negative pressure, and ammonia is perforated through wood-based plate from atmospheric pressure direction to negative pressure side.Under suction function, the infiltration of ammonia and wearing
Thoroughly should ratio very fast, such as Patent No.：Technical scheme disclosed in the Chinese patent of ZL99229606.4.But this method is still deposited
Equipment is excessively huge and complicated, input cost is too high, and consumes big calorimetric ammonia, secondary pollution of environment etc. can be caused to lack
Point, fails to be put in actual production activity so far.
B, vacuum processing method：It has been proposed that sheet material can be placed in vacuum environment, using material volatilization point under low pressure
Relatively low feature, need not heat, the free formaldehyde in sheet material just can separate out automatically.But it is not added with any supplementary meanss, only rely on
Vacuum environment, the speed that in sheet material, formaldehyde gases separate out is still very slow, and efficiency is very low.
Although above-described physical treatment method has one to be set for the release reducing harmful gass during sheet material uses
With, but treatment effeciency is low, speed slow, need to consume energy in a large number, secondary pollution, environmental issue can be caused to be difficult to solve, and is therefore difficult to big
Scale is promoted.
The above-mentioned various method reducing wood-based plate and its product Formaldehyde emission rate, or because high cost, being difficult to promote,
Or only have short run effect, can not solve problem at all, or secondary pollution can be caused, or efficiency very low, energy consumption is excessive,
Too high etc. the reason of operating cost, is all difficult to large-scale promotion application in high-volume, industrialized production.
