Description
Technical field
The present invention relates to a kind of sieve powder equipments, and in particular to a kind of powdery amino film plastics semi-finished product to after ball milling
The high speed sieve powder equipment and its sieve powder method sieved.
Background technique
Moulding compound is also referred to as thermosetting plastics, refers to the material that can be moulded in the present invention.Amino film plastics are also referred to as
Aminoplast is with the amino resins solid material as main component in synthetic resin, not according to the coherent condition of product
Together, amino film plastics are divided into powdery moulding compound and graininess moulding compound.Since graininess moulding compound will not put up a bridge (no in truck
It is known as putting up a bridge toward falling), therefore it is more suitable for the thermosetting plastics injection molding machine of automation.Amino resins is according to used raw material
Difference, be generally divided into urea-formaldehyde resin, melamine resin and aniline-formaldehyde resin etc., and amino film plastics then with
Corresponding amino resins is main component, using cellulose, minerals as filler, addition lubricant, curing agent, pigment and other add
Add object and be made, and is successively known as urea moulding material, melamine moulding compound and croak amine moulding compound.
There are two types of the manufacturing methods of traditional amino film plastics.The first is using one-step technology, second of use
Be two-step process.It is illustrated by taking urea moulding material as an example below.
The one-step technology includes slurrying, vacuum mixing, is crushed and sub-sieve (or tabletting).The slurrying step
Suddenly it is that formaldehyde and the methenamine as catalyst is added under stirring in pulping tank, after mixing, adds urea and made
Slurry keeps temperature of charge at 40 DEG C hereinafter, make formaldehyde and urea that addition reaction occur, generates monomethylol urea, and in system
Interior introducing methylol groups.The vacuum mixing step, which refers to, puts slurries into blender by filtering, then in blender
Remaining methenamine is added, pigment, lubricant and other auxiliary agents are then added, starts agitating paddle high-speed rotation, so that formaldehyde
Further addition reaction occurs with urea and generates dimethylol urea, and dehydrating polycondensation reaction (also referred to as precondensation occurs
Reaction) and generate the initial stage Lauxite of linear structure.Add cellulose (the usually pulverized small paper as filler
Piece), after being fully absorbed to slurries by cellulose, heater when so that material temperature reaching 40 DEG C, starts to vacuumize, vacuum
Degree is maintained at -85kPa hereinafter, making moisture content to 4% or so.Material slowly heats up up to rising to 75~80 DEG C, reacts 20 minutes
Afterwards, discharging.In this step, since polycondensation reaction is continuously increased molecular weight, the viscosity of material also constantly increases.Continuous
High-speed stirred in, conglomeration is dispersed material repeatedly again repeatedly, finally becomes the essentially identical uniform particle of size.Described
Pulverising step is to crush particulate material.The sub-sieve step is by sieving, between 20~100 mesh after taking pulverising step
Particulate material as amino film plastics finished product.The tableting step is that the material after pulverising step is pressed into several millimeters greatly
Small sheet finished product.Seen from the above description, although the process CIMS of one-step method is short, and airtightness is preferable, thus the feature of environmental protection
Preferably.But there are still more technical problems, first is that in its vacuum mixing step, due to final aqueous of material to be made
Rate drops to 4% or so, therefore 5 hours will be up to the vacuum dehydration time by reacting, and make energy consumption higher.Second is that if in vacuum
The color control of material is bad in whipping step, and the color of obtained moulding compound finished product can not then adjust, and serious person will lead to
This batch of product is scrapped.Third is that for moulding compound finished product, if other indexs such as demolding performace, curing time and moisture content are not
It is suitble to user to require, then can not also adjusts, serious person will also result in scrapping for product.
The technique of the two step method replaces vacuum mixing step compared with one-step method, by vacuum kneading step, and true
After empty kneading step, the drying steps using special drying equipment are increased, rather than directly true as one-step method
Moisture is sloughed using the method vacuumized in empty mixing apparatus.And then powdery finished product is obtained after crushing, ball milling, sieve powder,
Or graininess finished product is obtained after being granulated to the powder after sieve powder.Kneading in two step method, is conducive to addition and precondensation
Reaction, due to the drying steps being specially arranged, therefore in vacuum kneading, for the extent of reaction of moisture content and precondensation, has no
Harsh requirement.Therefore, the time of vacuum kneading step can be shorter, so that energy consumption declines.In ball milling step, due to
Related auxiliary material can be added in charging, and makes yield rate higher.But the sieve powder step in two step method, effect
Rate is lower, and environmental pollution is heavier.First is that being fallen in truck when ball mill goes out powder, so that dust from flying.Second is that truck is transported to
When on the operating platform of sieving machine, by sieving machine entrance manually is added with scoop, not only charging is uneven, but also raises out when charging
Dust it is larger to the Health cost of worker.Third is that using roto-siofter, the problems such as there are powder leakages.

The spacing of side is 2-4mm.Fixed wiper is set on the inside of the sieve of screening plant ".These descriptions illustrate either wiper
Or scraper plate is the component of fixed setting, and sieve is only the component rotated.The inventors found that: the mistake of powder
Net is powder to be squeezed out sieve under sieve rotation, through hairbrush, and then fall under the effect of gravity through sieve
It is exported in the discharge port below sieve, coarse powder then stays on sieve and is moved to the another of sieve with the rotation of sieve
End.Because hairbrush and sieve be in very close to state in, for sieve, using can shortly damage.Sieve turns
