Description
Technical field
The present invention relates to a kind of compound deal board of modification and its production technology for wardrobe purifying formaldehyde, belong to timber and add
Work field.
Background technology
The volatilization of formaldehyde and temperature it is in close relations.In general, temperature is higher, and the formaldehyde in furniture is more possible to wave
Hair.Expert introduction, room temperature often rise 1 DEG C, the formaldehyde of wood furniture and floor etc. volatilization, the formaldehyde in room air can be made dense
Degree rises 0.15-0.37 times.If formaldehyde content in furniture is not up to standard, just it is easy in summer release formaldehyde.
Wardrobe is furniture maximum in bedroom, and in bedroom, the main source of formaldehyde is wardrobe.Because
The air pollutants such as the formaldehyde in room are mainly derived from based on composite wood the various furniture of raw material, sheet material and various
Binder.Thus how much the content of formaldehyde in wardrobe sheet material is directly connected to bedroom Air Contamination.Sheet material is article of furniture
Main composition material, its quality directly determine the height of product quality and the price of product.Sheet material divides solid wood board and people
Make sheet material.Solid wood board sheet material is sturdy and durable, lines is naturally, burst size of methanal is few, mostly with the distinctive fragrance of natural timber.And
Wood-based plate is due to being the molding formed using timber or other non-wood plants as raw material by using adhesive or additive gluing
Product, thus inevitably discharge a certain amount of formaldehyde.The effect of wardrobe edge sealing is exactly to seal cutting section, prevents sheet material
Release formaldehyde.Many production wardrobe manufacturers to sheet material when edge sealing is carried out, in order to save production cost, wardrobe sheet material
There is no whole edge sealing, cause more formaldehyde pollutions.
Pine is a kind of confierophyte (common confierophyte has pine, China fir, cypress), and it has rosin taste, color light
The characteristics such as yellow, furuncle scar is more, react fast to atmospheric temperature, easily swell, extremely difficult natural air drying, thus need to through artificial treatment, as dried,
Degreasing removes organic compound, bleaches unified tree color, neutralizes tree property, be allowed to be unlikely to deform.
The present invention is intended to provide a kind of compound deal board of modification for wardrobe purifying formaldehyde, its internal bond strength is high, and
And the also unexpected effect for absorbing formaldehyde.
The content of the invention
Based on technical problem existing for background technology, the problem of existing for background technology of the invention, there is provided one kind is used for
The compound deal board of modification of wardrobe purifying formaldehyde, its internal bond strength is high, and the also unexpected effect for absorbing formaldehyde.
The purpose of the present invention is achieved through the following technical solutions：
A kind of compound deal board of modification for wardrobe purifying formaldehyde, it is prepared by the following method：
(1) raw material is prepared：Prepare pine cellulosic；
(2) enzyme pre-processes：Pine cellulosic is well mixed in a reservoir with water, enzyme liquid, regulation to desired pH value is
4.5, oxygen is passed through, 20-25min is reacted at 35 DEG C, taking-up drains；
The design parameter of the ferment treatment is：Laccase dosage:3U/g fibers；
(3) microorganism modification：
By bacillus subtilis, bacillus pumilus, acidophilus micrococcus according to quantity ratio be 1:0.3：0.1 be configured to it is compound
Microbial inoculum；
Pine cellulosic after ferment treatment is uniformly sprayed to upper microbial inoculum, fermented 28-31 hours in 39.5 DEG C, after fermentation ends,
Use warm water cleaning；
(4) secondary enzyme pretreatment：Pine cellulosic is well mixed in a reservoir with water, enzyme liquid, regulation to desired pH value
For 4.5, oxygen is passed through, 20-25min is reacted at 35 DEG C, taking-up drains；
The design parameter of the ferment treatment is：Laccase dosage:3U/g fibers, cellulase dosage:5U/g fibers；
(5) it is hot-forming：Fiber pulp after ferment treatment is poured into shaping frame, moisture filters out, while by the effect of liquid
Make slab smooth in the case where rocking, the fibre mat after draining first is cold-pressed water squeezing, then hot pressing；
Hot pressing mode is double-deck slab hot pressing, using the upper cold lower technique of heat, hot pressing temperature:110-115℃.
The present invention is advantageous in that：
The deal board bond strength that the present invention is prepared is high, the effect of also unexpected absorption formaldehyde, is adapted to use
In wardrobe, not only itself environmental protection, moreover it is possible to absorb formaldehyde, its formaldehyde absorption ability has reached the degree of activated carbon, is especially suitable for using
In wardrobe.
