Abstract
The invention discloses a method for dispelling harmful gases like formaldehyde in artificial boards and furniture using calefaction and vacuum technique. The method comprises the following steps: artificial boards or furniture such as a big core board, and a density board are placed in an airtight container and heated up to over 80 degrees centigrade; gases in the airtight container are pumped out through a vacuum pump, and air in the container is close to vacuum and kept for a while and repeated pump of vacuum can be carried out to fully eliminate harmful gases in the materials. The method has the advantages of full elimination of harmful gases without repeated pollution, simple and convenient ways and low cost.
Description
(1) technical field:
The present invention relates to a kind of method for removing, relate in particular to a kind of method of utilizing heating, vacuumizing method to dispel the harmful gass such as formaldehyde in artificial board, the furniture the harmful gass such as formaldehyde in artificial board, the furniture.
(2) background technology:
Along with the raising of people's living standard, the house finishing is very general, uses a large amount of finishing materials such as artificial boards such as lumber core, density board in the finishing, and the furniture of doing that has also uses this artificial board.But this sheet material uses a large amount of binding agents in the manufacture process kind, and most bonding agents belong to the chemosynthesis material.Contain the unsettled harmful substance of some molecular structures in these bonding agents, in use decomposite harmful gass such as formaldehyde, benzene easily, newly-decorated house is polluted, and new clothes occurring pungent, peppery eye phenomenon in repairing the house, and hangs up one's hat and damage for habitant's health.
Solution has following several at present: the one, utilize airy method, and unlimited door and window carries out convection current and in time discharges the harmful gas that finishing material discharges, and this method is simple.But the room needs can not use the method when airtight, for example when need utilize air-conditioning airtight warming or hot summer in cold winter.The 2nd, absorption method is put into porous materials such as active carbon in the room, and the harmful gas that the absorption finishing material discharges is perhaps put a few some harmful gass of basin plant absorbing in the room.This method people and active carbon or plant can occur and absorb harmful gas simultaneously, can not avoid the murder by poisoning to personnel.Three are to use photocatalyst, and photocatalyst is brushed on the finishing material, and photocatalyst resolves into oxygen atom to airborne oxygen molecule under irradiation under ultraviolet ray.The oxidized innocuous substance that the resolves into when harmful gas that discharges when finishing material runs into oxygen atom, this method effect is quite a lot of, but can not guarantee all harmful gass that discharges are decomposed fully, the gas molecule that perhaps discharges all runs into the oxygen atom that photocatalyst decomposes mutually, in addition, this method cost is than higher.Four are to use nature timber or high-grade sheet material, reduce the burst size of harmful gass such as formaldehyde, and this method one is to be subjected to resource limit, in addition cost height, generally not former these expenses of bearing of family.
All there is certain limitation in above several method.
(3) summary of the invention
In order to reduce the harm of toxic gas such as formaldehyde that decorative board material discharges, the invention provides a kind of heating, vacuumizing method of utilizing and dispel the formaldehyde in artificial boards such as lumber core, density board and the furniture and the method for other toxic gas health.
Technical scheme of the present invention realizes in the following manner:
A kind of heating, vacuumizing method of utilizing dispeled the formaldehyde in artificial board, the furniture and the method for other toxic gas: its process is as follows: artificial boards such as lumber core, density board and furniture are placed into more than the vessel in heating to 80 that can seal ℃, with vacuum pump the gas in the container is extracted out, make container interior, keep a period of time near vacuum.Also can carry out evacuation repeatedly, evacuation is put into air after keeping a period of time, is heated to after the temperature of requirement hermetic container evacuation again, removes the harmful gas in the container repeatedly.
Heating part can utilize the electric heating device direct heating, also can utilize conduction oil or overheated steam indirect.In sheet material manufacturer, can utilize the steam heating of boiler.
Four, good effect of the present invention is:
1, it is thorough to dispel harmful substance.The material unstable in the material, that boiling point is high, at the Undec material of room temperature, vaporization or decompose easily under the mal-condition of high temperature, vacuum, and in time being got rid of.In the use under the normal temperature condition, the material that can decompose seldom can not cause repeated contamination.
2, before finishing or before using, dispel, harmful substance can be brought into the room room is polluted.
3, when dispeling the back harmful substances, material is carried out vacuum drying, reduce the distortion of finishing material.
Five, the specific embodiment:
The present invention will be further described below in conjunction with implementing lining:
Embodiment 1: decorative board material is put into can be airtight, have vaccum-pumping equipment, drain tap, inside to have the container of electric heater unit, hermetic container, to the sheet material heating, when being heated to 80 ℃, cause near vacuum state with the vacuum pump evacuation, kept 10 minutes, open air bleeding valve and charge into air, behind the internal and external pressure balance 3 minutes, be heated to 80 ℃ once more, with the vacuum pump evacuation near vacuum state, keep 10 minutes or longer time, make that harmful substance fully decomposes, harmful gas is fully got rid of.Open air bleeding valve at last and charge into air, take out from container after the cooling, directly use.
Embodiment 2: to artificial board manufacturers such as lumber core, density board, with produce the decorative board material product is put into can be airtight, have vaccum-pumping equipment, drain tap, inside to have the container of steam heater, hermetic container, sheet material is heated, cause near vacuum state with the vacuum pump evacuation when being heated to 80 ℃, kept 10 minutes, open air bleeding valve and charge into air, behind the internal and external pressure balance 3 minutes, be heated to 80 ℃, evacuation once more, keep 10 minutes or longer time, harmful substance is fully decomposed, harmful gas is fully got rid of.Open air bleeding valve at last and charge into air, after the cooling product is taken out from container, pack then, transport, sell.
Embodiment 3: in furniture manufacturer, semi-finished product furniture before will spraying paint or spray paint after furniture put into can be airtight, have vaccum-pumping equipment, drain tap, inside to have the container of steam or hot oil heater, hermetic container, sheet material is heated, use the vacuum pump evacuation when being heated to 60 ℃, kept 10 minutes, open air bleeding valve and charge into air, behind the internal and external pressure balance 3 minutes, be heated to 80 ℃, evacuation once more, keep 10 minutes or longer time, make that harmful substance fully decomposes, harmful gas is fully got rid of.Open air bleeding valve at last and charge into air, after the cooling product is taken out from container, spray paint or pack, transport, sell.
Claims (2)
1, a kind of method of utilizing heating, vacuumizing method to dispel the harmful gass such as formaldehyde in artificial board, the furniture, its process is as follows: will decompose sheet material, the furniture of emitting poison and be placed into more than the vessel in heating to 80 that can seal ℃, extract the gas in the container out amount discharge container with vacuum pump, and make the interior maintenance of container near vacuum state, keep a period of time.
2, according to claim 1 with the method that heats, vacuum pumping method is dispeled the harmful gass such as formaldehyde in artificial board, the furniture, it is characterized in that heating means are to utilize the electric heating device heating.
