Disgrifiad

Troshaen Graffig, also called Panel, is an important part of membrane switch, which can provide control function and beautiful modern appearance. It is made by printing graphics and text description on such materials as PVC, PC and PET. It is composed of multi-layer polyester and adhesive, which can be directly connected with electronic equipment through flexible circuit board connector.

O ddeunydd i ddeunydd

The main materials suitable for making panel bilen are: PVC (polyvinyl chloride), PC (polycarbonate) and PET (polyester), with the thickness of 0.125 0.175 0.25, and three surfaces of sand, matte and smooth.

The physical and chemical properties of PC material are good, and it can adapt to many kinds of inks. It is the most common material for membrane switch panel. PC materials can be divided into sand surface and smooth surface. The reason for choosing sand surface materials is that the use of film switches is mostly electronic products, and the panel used as the control system does not want to be interfered by light, while the sand surface is only diffuse reflection, which will not produce bright reflection; at the same time, because the surface is disordered sand like, it has the function of masking scratches. In contrast, smooth materials do not have the above characteristics. But as a smooth material, if combined with the back printing, the color will appear more brilliant. In the case of strong decorative requirements and not frequently touched, the panel is often made of smooth materials, or due to the special needs of some display areas such as LCD, it is more favorable to choose smooth materials.

The price of PVC material is lower, about half of PC material. When producing popular civil products, PVC material can reduce production cost. At the same time, PVC material has good ductility, and can be used to cold press three-dimensional graphics. The thickness of smooth PVC plate is generally more than 0.5mm, and both sides are protected by PE or glue paper, most of which are used to make decorative panel; the thickness of PVC material on sand surface is generally less than 0.3mm, which is generally supplied by fixed length sheet, without coil.

The surface state of PET film is divided into smooth surface and fine sand. At present, the brands of British Autotex and Japan Toray are common in China. In addition, Autotex’s PH scratch resistant PET film is suitable for products with high requirements for scratch resistance, but the price is relatively expensive. Because the general properties of PET film can be replaced by PC film, there are not many PET panels, unless in some special occasions, such as insulation, resilience, solvent resistance and other conditions that other materials can not meet, PET will be used.

Manylion Cyflym

1. haen panel

Yn gyffredinol, mae haen y panel wedi'i wneud o batrymau a chymeriadau cain ar y daflen dryloyw di-liw fel PET a PC llai na 0.25mm. Oherwydd mai prif swyddogaeth haen y panel yw marcio a gwasgu allweddi, rhaid i'r deunyddiau a ddewiswyd fod â nodweddion tryloywder uchel, adlyniad inc uchel, elastigedd uchel a gwrthiant plygu.

2. haen clustog

Prif swyddogaeth yr haen clustog yw cysylltu haen y panel a'r haen gylched yn agos, er mwyn cyflawni effaith selio a chysylltiad. Yn gyffredinol, mae'n ofynnol i drwch yr haen hon fod rhwng 0.02-0.05mm, gyda gludedd cryfder uchel a gwrth-heneiddio; wrth gynhyrchu, dewisir y gludydd dwy ochr switsh pilen arbennig yn gyffredinol, ac mae'n ofynnol i rai fod yn ddiddos ac yn gwrthsefyll tymheredd uchel, felly rhaid i'r haen clustog hefyd ddefnyddio deunyddiau o wahanol nodweddion yn unol â'r gofynion.

3. haenau uchaf ac isaf o gylched rheoli

Mae'r haen hon yn mabwysiadu ffilm polyester (PET) gyda pherfformiad da fel cludwr ffigwr cylched switsh, ac yn defnyddio past carbon past arian neu bast aur arno i wneud iddo gael dargludedd. Mae ei drwch yn gyffredinol o fewn 0.05-0.175mm, a'r mwyaf cyffredin yw deunydd PET 0.125mm.

4. haen gludiog

Mae rhwng y gylched uchaf a'r haen cylched isaf ac mae'n chwarae rôl selio a chysylltiad. Yn gyffredinol, defnyddir gludiog dwy ochr PET, gyda'r trwch yn amrywio o 0.05 i 0.2 mm. Wrth ddewis deunydd yr haen hon, rhaid ystyried trwch cyffredinol, inswleiddio, cyffwrdd a selio pecyn allwedd cylched y cynnyrch yn llawn.

5. haen glud cefn

Mae cysylltiad agos rhwng y defnydd o glud cefn a pha fath o ddeunydd y mae'r switsh pilen yn cael ei gludo ag ef. Defnyddir y gludydd dwy ochr cyffredin, glud 3M, gludiog gwrth-ddŵr, ac ati yn aml.
