shading adhesive tape

Product Description:

Black and white glue, which belongs to one kind of shading tape, mainly used topaste the shading effect of optical display device, the material is PET, two coating into. The amount of coating 20.13/19.56, initial stress 1/1 (GB 4852), blackadhesion >1.79KG/IN (GB/T 2792), retention of >20H (GB 4851), peeling strength of 6 (90 ° peeling method), black shading rate of >99.9%, whitereflectivity of >88, temperature of -10-100 ℃, the tensile strength of the 200-270 newton;

Has the advantages of moisture resistance, anti ultraviolet radiation and shadingeffect is good, but also moderate viscosity, tear no residue after removal ofP65BW and X653-2, black and white glue is widely used in notebook computer.Mobile phone.PDA. digital display component backlight frame is fixed and shading effect, mainly used for mobile phone backlight, GPS backlight and otherelectronic display manufacturing industry.

P65BW and X653-2 were black and white glue is a double shading glue, whiteglue thickness is 0.065MM, the material is PET, flour adhesive >1.9KG/IN, black>1.7KG/IN >20H adhesion, retention, shading rate of >99.9%, reflectivity of >86%, temperature of -10-100 ℃, the tensile strength of 200-270 Newton; X653-2 black and white glue in the release degree PET film, cutting and rotary cuttinghas good processing performance, not easy in high temperature and high speed operation fragment. No glue overflow phenomenon. P65BW and X653-2 black and white glue has the following characteristics:

► thickness is very accurate, and the whole material thickness is very uniform.

► processing good, can cut to precise cutting shape, can also be used manuallyby adhesive bonding

► cutting high strength

► mainly for affixed to the product source side or product side sticking cloth,mainly cover and light reflecting effect

P65BW and X653-2 black and white glue is widely used in notebook computer.Mobile phone. PDA. digital display component backlight frame is fixed and the shading effect.

Quality guarantee period: from the delivery date of 12 months, at 21 ℃ (70 ° F)and 50% relative humidity environment preservation

Product structure: transparent PET film, acrylic adhesive, special black and white PET substrate, acrylic adhesive, transparent PET film

3 black and white glue cutting process

As long as the master of the die-cutting craft basic principle, in the actual production and operation, constantly sum up, master various skills, familiar with the performance of production equipment, the strict implementation of the requirements of the production process, can timely and correctly excluded for various problems occurred in the production, and create favorable conditions for the smooth production of high-quality die-cutting indentation products. Die - cutting knife, indentation line, elastic rubber strip, pressure is cut a few biginfluence factors in the analysis process, the above failures, we can seeproduction problems mainly related to these factors, the selection rules are summarized as follows:

1 die cutting knife

Die - cutting knife have single, double sided, dentate, line of blade, the thicknessfrom 0.5mm to 1.5mm is divided into a plurality of specification. Select theappropriate models and specifications of the cutting tool is the key to guarantee the cutting quality. Good quality die-cutting knife steel quality, exquisite backcarbon treatment, heat treatment, precision. Die - cutting knife should be selected according to the product specification and quality, customer requirements and the complexity of box type. Rotary die-cutting common serrated knife, cut the cardboard more thick, die-cutting knife tooth number on unit lengthshould be less and less, and more, in order to achieve the optimum pressure.

The 2 line indentation

And the choice of cutting knife, indentation line selection is also very important,product indentation is not obvious or fracturing, often is caused by improperselection of indentation line. High quality indentation hardness of steel wire should be moderate, strong stability, thread smooth, circular symmetry, lowheight, thickness deviation, complete specifications. The indentation line heighthas a variety of specifications, should be selected according to the indentationcardboard thickness varies (note that for corrugated board shall make corrugated flattening thickness measurement).

Should follow the general formula: indentation line height die cutting knife high -pressure cutting board thickness, pad of paper thickness suppliers to provide relevant indentation line selection standard; only for reference, but to chooseaccording to their own situation in practical application.

1 into the feeding machine bottom material to the single seat die-cutting machine,in single seat die-cutting machine discharge rack of black and white filmpackaging materials, the black and white glue flour release paper waste winding,and the black and white flour with double-sided adhesive polyester base materialthrough single seat die-cutting machine.

2 after cutting machine, punching hole, the inner frame and at the side of wasteproducts.

3 after the three seat laminating machine, scrap black double-sided adhesiveprotective film first put masking tape row frame, the second step with wastepolyester Row Black double-sided adhesive inner frame, frame and the exhaustout the black and white black double-sided adhesive protective film waste, the third step again with a layer of polyester film.
