Dusha garaafka qaybta muhiimka ah ee beddelka xuubka

    Duubista garaafka, oo sidoo kale loo yaqaan Panel, waa qayb muhiim ah oo ka mid ah beddelka xuubka, kaas oo bixin kara shaqada xakamaynta iyo muuqaalka quruxda badan ee casriga ah. Waxaa lagu sameeyay daabacaadda sawirada iyo sharraxaadda qoraalka ee agabyada sida PVC, PC iyo PET. Waxay ka kooban tahay polyester-lakab badan iyo koollo, kaas oo si toos ah loogu xidhi karo qalabka elektarooniga ah iyada oo loo marayo isku xirka guddiga wareegga dabacsan.

Description

Daad-mareen garaafka, 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.

The main materials suitable for making xuubabka 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.

Faahfaahin Degdeg ah

1. lakabka guddi

Lakabka guddigu guud ahaan waxa uu ka samaysan yahay habab fiican iyo jilayaal xaashida hufan ee aan midabka lahayn sida PET iyo PC in ka yar 0.25mm. Sababtoo ah shaqada ugu weyn ee lakabka guddidu waa calaamadeynta iyo riix furayaasha, alaabta la doortay waa inay lahaadaan sifooyinka daahfurnaanta sare, dhejinta khad sare, dabacsanaan sare iyo caabbinta laalaab.

2. lakabka barkin

Shaqada ugu weyn ee lakabka barkinta waa in si dhow loo xiro lakabka guddiga iyo lakabka wareegga, si loo gaaro saameynta xiritaanka iyo isku xirka. Dhumucda lakabka ayaa guud ahaan looga baahan yahay inay u dhexeyso 0.02-0.05mm, oo leh awood sare oo viscosity iyo anti-gabowga; wax soo saarka, xabagta gaarka ah ee xabagta laba-geesoodka ah ayaa guud ahaan la doortaa, qaarna waxaa looga baahan yahay inay noqdaan kuwo aan biyuhu lahayn oo heerkulka sare u adkaysta, markaa lakabka barkinku waa inuu sidoo kale isticmaalaa qalabyo sifooyin kala duwan leh sida shuruudaha.

3. lakabyada sare iyo hoose ee wareegga xakamaynta

Lakabkan waxa uu qaadanayaa filimka polyester-ka (PET) oo leh waxqabad wanaagsan oo ah sida xambaara sawirka wareegga wareegga, wuxuuna isticmaalaa koollada qalinka ah ee kaarboonka ama koollada dahabka ah si uu u yeesho koronto. Dhumucdiisu guud ahaan waxay ku dhex jirtaa 0.05-0.175mm, tan ugu caansanna waa 0.125mm PET walxo.

4. lakabka koollada

Waxay u dhaxaysaa wareegga sare iyo lakabka hoose ee wareegga waxayna ciyaaraa doorka xiritaanka iyo isku xirka. Guud ahaan, koollada laba-geesoodka ah ee PET ayaa la isticmaalaa, iyadoo dhumucdiisu u dhaxayso 0.05 ilaa 0.2 mm. Markaad dooranayso walxaha lakabkan, dhumucda guud, daboolka, taabashada iyo xidhitaanka xirmada furaha wareegga ee alaabta waa in si buuxda loo tixgeliyaa.

5. Lakabka xabagta ee dambe

Isticmaalka xabagta dhabarka waxay si dhow ula xiriirtaa nooca shay ee furaha xuubabka lagu dhejiyo. Xabagta caadiga ah ee laba-geesoodka ah, koollada 3M, koollada aan biyuhu lahayn, iwm. ayaa badanaa la isticmaalaa.
