Q:What's the repair method of membrane keyboard?
Method steps are as follows: 1. Disassemble the keyboard. Note that when you disassemble the keyboard, be sure to make the button surface (that is our operation side) downward, and circuit board upward, otherwise, the conductive plastic on each key may come off consequently, bringing trouble to your repair work. 2. Disassemble the circuit board. There is usually a layer of membrane made of soft plastic on the circuit board, and key flat cables are engraved on the membrane. Preferably use the cotton soaked in alcohol with the concentration of more than 97% (the cotton soaked in medicinal alcohol with the concentration of more than 75% is also ok, because I once used , but it is best to use the former one) to gently scrub the circuit board twice. For the circuit where key failure happens, scrub it more times. 3. Examine the conductive plastic of the keys which don't work, and if a lot of dirt is accumulated on the plastic, scrub it in the same way as the above. Suppose the conductive plastic is damaged, then I advise you to replace the conductive plastic on the not commonly used keys to the damaged part. Although in this way, it can not play all the keyboard functions, but at least it can extend the life of the commonly used keys. 4. Remove dirt in the inside corners of the keyboard with tools of writing brush, tiny brush, etc. and be careful to be gentle.
Q:Is HDPE geomembrane the same as polyethylene polypropylene fiber?
Of course it isn't. They are totally different products. HDPE geomembrane, also known as high density polyethylene,is a single-layered plastic sheet, mainly used for the anti-seepage projects, such as refuse landfills, tailings treatment plants, sewage treatment tanks, etc. Polyethylene polypropylene fiber is a multi-layered composite waterproofing membrane, and its raw materials are PP non-woven fabric and polyethylene. It is mainly used in moistureproof and waterproof projects, such as roof, wall, toilet, basement, refregeration house, bridge, pool, underground pipeline, etc. These two products are of different raw materials, molecular structures and use. Therefore, they are not the same.
Q:Why the lacquer film is not hard enough?
Generally speaking, there are three reasons. First it is brushed too thick. Second the time is not enough. Third, the temperature is too low.
Q:How to tear off the plastic wrap?
It can be solved simply by changing the position of the metal saw blade on the plastic wrap box. Matters need attention: When tearing, you should press against the blade head with one hand. The result of my experiment is - even for the very thin plastic wrap with the width of only 3cm, it can be torn off easily and perfectly.
Q:Principle of energy saving insulation film?
Energy-saving insulation film maintains a constant indoor temperature by preventing the indoor and outdoor thermal convection. in summer when the outdoor temperature is higher than the indoor, energy-saving insulation film keeps the heat outside, keeping cooling inside; in winter, when outdoor temperature is lower than indoor temperature, saving insulation film prevent cold outdoor from entering indoor, and retain heat generated inside. the indoor temperature is not affected by the outdoor temperature. Energy-saving insulation film solar control performance is equivalent to 30 cm brick wall compared to a layer of insualting film, blocking up to 50% -90% of heat that enters into the house through the glass windows. Experiments show that when the outdoor temperature is 38-39 degrees Celsius, the application of energy-saving insulation film HONMO room indoor temperature lower than ordinary glass room 3-5 degrees.
Q:What kind of membrane switch material is good?
Membrane switch is an operating system integrating the key function, indicating element, and instrument panel as a whole. It is composed of four parts: panel, upper circuit, isolation layer, and lower circuit. It is a kind of normally open switch and its up and down contacts are in a off state under normal circumstances. When the membrane switch is pressed, the upper circuit contact deforms downward, and realize the contact with the lower circuit plate and breakover. When you release your finger, the upper circuit contact will bounce back, the circuit is off, and the loop will trigger a signal. Membrane switch is rigorous in structure with nice appearance and good seal. It has the characteristics of anti-humidity and long service life.
Q:What are the functions of computer anti-spy protective film?
The functions of computer anti-spying film: 1, protect top secret privacy with visual area of 60 degrees, namely invisible beyond left and right 30 degrees (invisible beyond 30 degrees means seeing from the left, invisible beyond 30 degrees from the far left of the screen, when seeing from the right, invisible beyond 30 degrees from the far right of the screen) 2. surface peening treatment, scratch resistance, wear resistance, hardness of 4-5h 3, strong glare resistance reaching 99.9%, relieving eye fatigue. 4, UV resistance is up to 96% 5, low frequency radiation resistance reaching 99.9% 6, anti-static 7, enhancing contrast ratio, making the effect better 8, anti-scratch, light reflection resistance, surface oil resistance and protecting the eyes.
Q:How to use the mobile phone laminator?
The mobile phone is fixed on the mobile phone slot, and then switch the torque on the back to lift the height to the mobile phone screen. The method of application of mobile phone laminator read 2 take out the fixed SMD, one side is attached on the mebrane number 2, the mebrane is aligned at the back of screen mobile phone, and then the other side of the fixed SMD is pasted on the lifting platform. The operation method 3 of mobile phone laminator open the mebrane and clean the mobile phone screen, uncover the number 1 label of the mebrane, and press slowly the mebrane by the roller. Method 4 of using mobile phone laminator tear off the number 2 film, wipe the screen of the mobile phone with a clean cloth, which can squeeze out the rest of the bubble. Sticking the film is finished. The notice of the method of using mobile phone laminator It must clean the screen mobile phone before sticking the film.
Q:What are the specifications of plastic film
According to the different plastic film manufacturing method, it can be divided into pressure Ting film, blown film; according to some special properties of plastic film , respectively, it has seedling film, no drop film, colored film, thin covering film, film width, packaging films etc. According to the different thickness and width of plastic film, there are different kinds of specifications. Hips 476l injection molding grade Yangzi BASF hips 466f injection molding grade Yangzi BASF hips 495F injection molding grade Yangzi BASF GPPS pg33 injection molding grade Taiwan Chimei GPPS 666d general level of Yanshan Petrochemical
Q:Which is better for geomembrane hot melting in the middle of sliding layer of high-speed railway bridge two cloth and one membrane, lapping or docking? And what is the lapping length if it is lapping hot melting?
In general, it should not be cut according to graphic size. Shorten joint length and strain as far as possible. After geomembrane pavement, the lap width between films should be not less than 10 cm. 4. Usually set at a corner and abnormal section. 6, arrange along the gradient direction and avoid accidental damage to membrane when the temperature is low. Lap width between membranes is generally not less than 10 cm. You should measure the accurate relative size. Do not weld as far as possible during geomembrane pavement . In addition to the special requirements, Do not walk on the membrane or carry on the membrane.
