Roller brush knowledge introduction

At present, most of the roller brushes are made of acrylic fleece or foam plastic with I-shaped iron handle. They are used for large-area paint roller coating. They are an ideal tool for building decoration and decoration projects. Paint, organic or inorganic exterior paint, anti-rust paint, wallpaper paste and other materials.

Instructions:

(1) Dip a clean roller brush into the paint bucket, and after it absorbs an appropriate amount of paint, it can be rolled on the working surface. Roll horizontally first. As the paint on the roller brush decreases, the rolling speed can be appropriately accelerated. When the paint on the roller brush is basically used up, roll vertically to level the uneven paint until the spine is coated. . For a good gloss, lightly brush again with a bristle brush.

(2) The used roller brush does not need to be washed, just soak it in paint or clean water, and it can still be used the next day. When a project is completed, it can be washed with gasoline or thinner, usually in the paint tray. After cleaning, the cylinder sleeve is dried and the fluff on the cylinder is loosened to prevent the fluff from tangling with each other during storage. When storing, wrap the sleeve with kraft paper, the kraft paper is slightly wider than the sleeve, and stuff the excess into the sleeve. It can also be wrapped in plastic wrap, but punch holes for air circulation to prevent mildew. The sleeve should be stored upright, otherwise the fluff will press marks, the foam roller brush cannot be cleaned with gasoline, and it should be wrapped with paper after cleaning.
How to choose a good quality roller brush


Plush:

Everyone knows that roller brushes are used to apply paint and paint. Then, the plush of the roller brush is the key to the quality of the roller brush.

Density:

High-quality roller brush, high density of plush, more than 950 grams per square meter, large amount of dipping paint, large brushing area, firm plush, not easy to lose hair, no thread opening. Long use time, smooth surface. The plush density of low-grade roller brushes is below 700 grams per square meter. Loose weave, easy to shed.

Purity:

100% acrylic fiber, good quality, good dipping paint, high price, and plush containing a certain proportion of polyester is cheaper.

The quality of the plush of the roller brush head determines the service life and use effect of the roller brush. At the same time, 60% of the cost of a roller brush is determined by the plush.

How to distinguish the pros and cons of plush? As far as China's current roller brush manufacturing industry is concerned, roller plush can be roughly divided into three categories: shuttle weaving (horizontal weaving, warp and weft weaving), warp weaving , circular weaving. Among them, the products of shuttle weaving method have the best quality and high price, while the products of circular loom weaving method are relatively low.

According to China's current situation for the plush textile industry, the shuttle machine plush machine, because the investment in the imported double rapier loom assembly line for this product is too large, currently there is only one factory in Shandong, and warp knitting products are currently There are already five or six factories operating in China. The cost of circular knitting machines is relatively cheap, and there are hundreds of factories in China that can produce products.

The earliest roller brush products were all shuttle products. The earliest roller brush products exported from China to Europe were also shuttle products. At present, European customers require products with strict quality, which are also shuttle products.
structure:

In addition to the plush thought, the internal structure of the roller brush is also very important. At present, it can be divided into three categories: one is the German plug-in structure, the second is the American roller frame structure, and the third is the Chinese screw structure.

The advantages and disadvantages of the plug-in structure are: the handle is simple and cheap, but the brush head is complex and expensive. Can be used with interchangeable heads. The advantages and disadvantages of the American roller frame structure are: the brush head is simple and cheap, but the roller frame is complex and expensive. Can be used with interchangeable heads. Chinese screw-type structure, simple to manufacture, low price, uneven quality, and difficult to replace the brush head. Even the handle is a one-time product. The use of waste, for the user, the cost is higher. For the products of individual factories, because there is no inner tube, there is a phenomenon that the paint can not flow in and come out. There is also the phenomenon of falling off the cover and the plush falling off.

Plastic parts material:

The export product requirements are nylon tube and new material handle. The new material is blocked, and the environmental protection requirements are strict.

Adhesive:

Ordinary adhesives, etc. The use of these materials will directly affect the use of roller brushes. German formula special adhesive is resistant to thinner acetone, Tianna water, etc. Ordinary adhesives are not resistant to use, especially high-grade paints, and low-grade rollers cannot be used for brushing with relatively viscous adhesives.

Testing method:

Tear down the plush by hand from the inner plastic parts of the drum, the drum of good quality is difficult to destroy. Poor quality is easy to tear off.
Bearing test:

Good quality roller brush, one person stepping in the middle of the roller brush head. The roller brush can support the weight of one person. There are no changes to the roller brushes. And the poor quality roller brush, the plastic parts inside will be broken when you pinch it with your hand.

Process manufacturing:

The hair surface of the roller brush is flat, without gaps, without bagging, and without pressing hair.

In addition to this, there are also differences in the diameter of the drum, the diameter of the handle (4-8mm), the material of plastic parts, electroplating and so on.
There are many sizes of roller brushes, how to choose?

Answer: Common lengths of roller brushes include 2, 4, 6, 7, 8, 9, and 10 inches, and one inch is about 2.54cm; roller brushes above 7 inches can be selected for large-scale construction, and roller brushes below 6 inches are used for Small area construction and corner, narrow area construction.
