Tanning brush factory teaches you four production methods of brush roller

Four production methods for brush rollers :
1, direct planting
This is a way of zui tradition, which is to plant nylon yarn and abrasive wire directly on the grinding roller.
Disadvantages: Although the strength can be very high, but the cost of planting is high, and it is impossible to replace it locally. It is an initial helpless choice.
2, winding type
Advantages: A planting method introduced from abroad, the abrasive wire is made into a metal strip which can be wound, and then wound on a sanding roller, which can be customized according to the length of the sanding roller.
Disadvantages: Since the abrasive wire is stuck on the metal strip, it will cause the phenomenon of drawing (the abrasive wire is drawn out), the strength is not high, and only the two ends are fixed after winding, so it is difficult to make the middle tight, if one end is loose If you drop it, you will have an accident.
3, nylon sleeve
Advantages: simple production process
Disadvantages: It is a kind of faulty zui. The thermal expansion and contraction of nylon will cause the nylon to become longer, so that the nylon at both ends of the roller body will grow out of the sanding roller and the machine will also cause the nylon sleeve to burst and make the whole mill The roller is scrapped; the bristles are planted with the riding nails, the strength is not high, and the hair is easy to be removed; the strength of the nylon is not high, the planting density cannot be increased, and the like...
4, aluminum brush roller - new sanding brush roller
It is an advanced brushing roller, which is made of aluminum alloy cylinders. It can be customized with any length of brush roller. The high-strength aluminum alloy substrate can make the planting density high, and it can be used for the hair-planting technology of the front edge of Zui. It does not cause cracking and lengthening like nylon; the roller body can accurately check the dynamic balance. More importantly, the use of this brush roller is really fast replacement, quick trimming and unlimited extension.

Test Kits

Diagnostic reagents can be divided into two categories: in vivo diagnostic reagents and in vitro diagnostic reagents. It is mostly a reagent for detection by the reaction between antigen and antibody.
A: Classification of in vitro diagnostic reagents:
1. In vitro biodiagnostic reagents managed as drugs include:
1. Blood type and tissue type reagents;
2. Microbial antigen, antibody and nucleic acid detection reagents;
3. Tumor marker reagents;
4. Immunohistochemistry and human tissue cell reagents;
5. Human genetic testing reagents;
6. Biochips;
7. Allergy diagnostic reagents.

2. In vitro reagents managed as medical devices include:
1. Clinical basic test reagents;
2. Clinical chemistry reagents;
3. Blood gas and electrolyte determination reagents;
4. Vitamin determination reagents;
5. Cell histochemical stains;
6. Autoimmune diagnostic reagents;
7. Microbiological test reagents.
B: According to medical test items, clinical diagnostic reagents can be roughly divided into clinical chemical test reagents, immunology and
Serological testing reagents, hematological and cytogenetic testing reagents, microbiological testing reagents, body fluid excretion
Detection reagents, genetic diagnosis reagents, etc. Among them, the market share of clinical chemistry
The largest, close to 34%; followed by the immunology market, accounting for about 29%. Novel immunodiagnostic reagents and genetic diagnostic tests
The reagent was developed in the late 1980s, and it is the most common diagnostic reagent for all current diagnostic reagents, regardless of technology or market.
The fastest growing product.
