Description
Technical field
The present invention relates to industrial analysis instrument apparatus field, more particularly to a kind of production technology of sheet material and inorganic glue change
Property.
Background technology
Sheet material is commonly made to the flattened rectangular constructional material plate of normal size, makees wall, ceiling or the component on floor.
Refer to the metallic plate that forging, rolling or casting form more.It is divided into thin plate, middle plate, slab, special heavy plate, is commonly made to normal size
Flattened rectangular constructional material plate.Sheet material can be divided into solid wood board, the major class of wood-based plate two by material classification；It can be divided into by shaping classification
Solid slab, clamping plate, fiberboard, decoration panel, fire-proof plate etc..
Clamping plate is also to be peeled into veneer or by flitch slicing into veneer by juggle into glued board, then it is glued with adhesive and
Into three layers or multilayer board-like material, generally use odd-level veneer, and make the orthogonal glue of machine direction of adjacent layer veneer
Conjunction forms.Glued board is one of furniture common used material, is a kind of wood-based plate.It is mutual that one group of veneer generally presses adjacent layer grain direction
Vertical assembly gluing forms, and usual its dash board and inner plating are symmetrically arranged at the both sides of central core or plate core.After gluing
Veneer is suppressed under conditions of being heated or not heated and formed by the crisscross slab being made into of grain direction.The number of plies is generally strange
Number, minority also have even number.The physics in direction, engineering properties difference are smaller in length and breadth.Conventional has three-ply board, five-ply board etc..It is glued
Plate can improve timber utilization rate, be a main path for saving timber.Also be available for aircraft, ship, train, automobile, building and
Packing case etc. acts on material.Common length and width specification is:1220 × 2440mm, and thickness specification then typically has:3、5、9、12、15、
18mm etc..Chief species have:San Cheong, willow are pressed, poplar, Eucalyptus etc..
The patent No. 201510646389.1, the liquid adhesive and wood-based plate processing method of a kind of no aldehyde, by above-mentioned liquid
Adhesive coated is combined into slab on wood single-plate；Then, slab is sent directly into hot press and carries out hot pressing, hot pressing temperature
Spend for 95 DEG C ± 5 DEG C, hot pressing pressure 10KG/cm2~14KG/cm2；Finally, it is neat to stack by the heating platen after hot pressing, next day
It can carry out sawing the process such as side and sanding.A kind of wood-based plate processing method, it is the processing method of particieboard, including：First, will be upper
Liquid adhesive is stated to be sufficiently mixed with wood shavings and mat formation into the slab of multiple-layered wood chipboard；Then, slab is sent directly into heat
Hot pressing is carried out in press, hot pressing temperature is 95 DEG C ± 5 DEG C, hot pressing pressure 10KG/cm2~14KG/cm2；Finally, by after hot pressing
Heating platen, neat to stack, next day can carry out sawing the process such as side and sanding., it is necessary to using aluminium sheet or steel when being combined into slab
Plate carries out hot pressing as backing plate together with slab.A kind of wood-based plate processing method, it is the processing method of fiberboard, including：It is first
First, wood fibre of the moisture content less than 6% is stirred with above-mentioned liquid adhesive, wherein the weight of liquid adhesive
For the 35%~40% of fibre weight；And by the fiber lay down of glue mixing on teel pallet, form fibre mat；Then,
Fibre mat is sent directly into hot press and carries out hot pressing, hot pressing temperature is 120 DEG C, and leading portion hot pressing pressure is 20KG/cm2, heat
The pressure time is set as 20 minutes, and back segment hot pressing pressure is 6KG/cm2, hot pressing time is set as 10 minutes；Finally, by after hot pressing
Heating platen, neat to stack, next day can carry out sawing the process such as side and sanding.Need log being processed into thickness not by rotary-cut
Together, the very high veneer of moisture content, then moisture content is prepared into the veneers of 15%- 20% by veneer dryer, because annual ring change is easy
Contraction distortion, needing in its process to dry, hot pressing leveling, technique is complicated, and the sheet material of traditional mode of production is produced using three-aldehyde glue more,
Containing harmful formaldehyde, formaldehyde is more highly toxic material, the formaldehyde on China's toxic chemical priority acccess control list
It is in second.Formaldehyde is defined as carcinogenic and causes deformed material by the World Health Organization, is generally acknowledged allergen,
It is one of potential strong mutagen.Research shows：Formaldehyde has strong carcinogenic and tumor promotion.Lot of documents is recorded, first
Influence of the aldehyde to health is mainly manifested in allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immune work(
Can be abnormal etc..When its concentration reaches 0.06-0.07mg/m3 in every cubic metres of air, children will occur slightly to pant.
When formaldehyde content in indoor air is 0.1mg/m3, just there are peculiar smell and sense of discomfort；When reaching 0.5mg/m3, eyes can be stimulated,
Cause and shed tears；Reach 0.6mg/m3, throat discomfort or pain can be caused.When concentration is higher, nausea and vomiting can be caused, chest of coughing
It is vexed, asthma even pulmonary edema；When reaching 30mg/m3, causing death immediately is understood.And sheet material is that inevitably house ornamentation is built in finishing
Material, how to simplify its preparation section, and the problem that harmful material is our urgent need to resolve is free of in preparation process.
The content of the invention
