Detailed description of the invention
Fig. 1 is technological process of production schematic diagram of the invention；
Specific embodiment
Nylon ball is cylindrical shape of the length between 0.2mm-2mm, each component and its weight percent are as follows: poly- second
Alkene soil 6.77%, adhesive 4.51%, softened water 3.75%, polyimides 7.51%, rubber 7.51%, alkali cellulose
22.55%, latex diluent 3.75%, resin 9.02%, nylon 4.51%, basic cellulose 30.09%.
The preparation method of nylon ball comprising following processing step:
Each component described in claim 1 is weighed by corresponding weight percent, and is stirred for mixing by the first step
Material；
Mixture is entered list by automatical feeding system after being heated at high temperature between 220 DEG C -260 DEG C by second step
It carries out being extruded into Filamentous semi-finished product in screw extruder；
Third step, Filamentous semi-finished product, which enter in cold water storage cistern, to cool down；
Filamentous semi-finished product be heated to after level-one traction stretches by hot bellows by the 4th step, stretched dragger
Second level traction is carried out between 190 DEG C -220 DEG C again to stretch, air-cooled to 80 DEG C after two to three-stage traction stretch, forms nylon yarn；
5th step winds the rolling machine of nylon yarn；
Nylon yarn is cut into length and the consistent cylindrical body nylon ball of diameter by the 6th step, cutter device.
Further, it is put in storage after the nylon ball that cutting is completed being sieved, detected.
Further, the sieve that three-layer screen aperture is gradually reduced is passed sequentially through to be sieved.
The purposes of nylon ball: processing is brightened for the flash of workpiece surface, flash processing and surface polishing.
It specifically can be used for the surface pretreatment of circuit board using the nylon ball of process production, electronic component
Except excessive glue；Epoxy resinous optical detector is cleaned, surface will not be made to become opaque；It can be from glass fibre, carbon fiber and resin
Paint removal and removing coating on the workpiece of class；Cleanable rubber, plastics, glass and compression mod, without damaging die size precision；
Most of aircraft paint is removed, but retains electroplated layer；For removing tiny slight burr, without hurting workpiece surface.
The nylon ball produced through this process amplifies 30 times of observations, removes the irregular product of surface shape, does not conform to
Lattice rate≤0.3%.
When carrying out screening detection, tested nylon ball 1000g is weighed up not less than the balance of 0.1g using precision, is then placed on the
It is sieved in one layer of sieve, collects the nylon ball remained on sieve, weighing calculates the percentage for accounting for total amount；Then again by first
The nylon ball that layer sieve passes through is put into the sieving of second layer sieve, collects the nylon ball remained on second layer sieve, calculates and account for
The percentage of total amount；Then the nylon ball that second layer sieve passes through is put into the sieving of third layer sieve again, collection remains in third
Nylon ball on layer sieve, weighing calculate the percentage for accounting for total amount, can obtain size distribution proportion.
First layer sieve: mesh size is the+0.1mm of nylon ball nominal dimension；
Second layer sieve: mesh size is the ± 0.0mm of nylon ball nominal dimension；
Third layer sieve: mesh size is the -0.1mm of nylon ball nominal dimension；
Carry out the test of durability degree:
500g pellet and spare 100g pellet are randomly selected from tested pellet, and 100g pellet is all put into tired survey
In test-run a machine, setting 500 switchs to a circulation, after a cyclic test, with nominal diameter 0.2mm standard separating sieve, to having tested
Pellet and dust sieved, remove dust after, remaining pellet is supplemented with spare pellet.And so on, continue
Cyclic test reaches 100g until losing pellet gross weight, thus calculates, reaches the fatigue tester revolution of 100g pellet loss, i.e.,
For the durability degree for being tested pellet.
The calculation formula of durability degree are as follows:
The accumulative total revolution-of circulation rotating [(500 ÷ last time circulation loss in weight) × (stack loss total weight-
100)]
It is as follows to finally obtain related finished product data:
| Title | Nylon ball |
| Hardness | HRC120 |
| Particle is poor | Maximum magnitude deviation ± 0.02mm |
| Density | 1.13g/cm3 |
| Water absorption rate (23 DEG C) | 1.8% |
| Drawing force | 750kg/cm2 |
| Bending stress | 1000kg/cm2 |
| Molding shrinkage | 1.2% -1.5% |
| Fusing point | 220℃ |
| Surface resistivity | <109Ω |
| Durability degree | 15000 circles |
Since the nylon ball produced with this process has following features
1. there is certain toughness, without machinability, in use will not damage to product to be processed.
2. mining height molecule aggregation raw material, peculiar shock resistance.
3, micron order processing procedure, precision is good, can reduce product to be processed workpiece fraction defective.
4, weight environmental protection, self raising flour dirt are suitble to the long-acting use of repetitive cycling, can more reduce the production cost of user.
Specifically for carrying out deburring and overlap to workpiece surface, or polishing is carried out to metal surface and is brightened, can subtracted
The number of few replacement polishing ball, reduces production cost, and can be further ensured that throwing with the polished metallic surface of effective protection
Light quality.
It can be also used for the surface pretreatment of circuit board using the nylon ball that the process produces, removing for electronic component is overflow
Glue；Epoxy resinous optical detector is cleaned, surface will not be made to become opaque；Can from glass fibre, carbon fiber and resinae
Paint removal and removing coating on workpiece；Cleanable rubber, plastics, glass and compression mod, without damaging die size precision；Removal
Most of aircraft paint, but retain electroplated layer；For removing tiny slight burr, without hurting workpiece surface.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
