Ordinary ordinary Wrap Tape in the market a lot, many industries have to use, how can we distinguish good Wrap Tape:
Ordinary adhesive Wrap Tape glue is acrylic glue, also known as pressure-sensitive adhesive Wrap Tape, the main component is unitary IA purpose. IA unitary purpose is a kind of polymer active substances, the temperature of the molecular activity has a certain impact.
The mI fat content of the glue directly affects the use of the Wrap Tape. Many of the Wrap Tapes think that the adhesive Wrap Tape is good for the glue, in fact, it is wrong. Adhesive Wrap Tape is good or bad in use, there are two standards, one is the initial tack, one is the holding force, the two are inversely proportional.
Generally speaking, the low adhesive Wrap Tape is coated with less glue to teach, generally only about 20 microns, such as stationery Wrap Tape, Wrap Tape for general promotional bundling. Normal sealing Wrap Tape initial adhesion between 15-20, the thickness of this Wrap Tape glue generally 22-28 microns. This Wrap Tape is in line with the standard thickness.
In today's Wrap Tape market, many Wrap Tapes are mixed with impurities, just like the yellow, green, and yellow Wrap Tapes they belong to, which are all inferior Wrap Tapes.
Why Wrap Tape can take evidence of dust footprint?
(1) The principle of dust footprint formation.
The formation of dust footprint is divided into two categories:
One is dust plus layer footprint. Dust plus layer footprint is the soles convex surface attached to the dust in the process of contact with the object to bear on the surface, the dust transferred to bear on the surface of the object formed footprint.
One is the dust reduction footprint. Dust delamination footprint is the soles of the convex contact with dust bearing objects, the convex surface of the shoe will withstand the dust on the surface of the object sticky footprint formed.
(2) The principle of clinging to the dust footprint is to use the good transparency of the Wrap Tape, the high persistence strength, and how much the dust 2 reflected by the dust footprint itself and its own fixing property attach the dust footprint cat to the adhesive Wrap Tape Separating the dust footprint from the receiving object and enhancing the contrast of features by means of black substrate, strong light, polarizer, scanning and image processing, etc., the adhesive Wrap Tape can show the characteristics of dust footprint more clearly.
