- Q:how is the metal plating ceramic film?
- Further improve separation precision and stability of the ceramic membrane materials to achieve continuous and efficient operation at nanoscale level in liquid separation field as well as in the field of gas separation. anti temperature ceramic separation materials of large aperture and high porosity so as to achieve long term and stable gas-solid separation in the field of efficient use of resources and environmental protection. to achieve treatment of the ceramic film surface and expand the application scope by changing hydrophilia and hydrophobicity of the surface and charge performance, biology compatibility.
- Q:Which kind of the mobile phone screen protector is better?
- Films are generally divided into two types of membrane of high grade of transparency and frosted membrane. Membrane of high grade of transparency has high permeability through the natural brightness, it looks bigger brightness, but the drawback is reflection of light in the bright place which will make you harder to clearly see the text on the screen. But the frosted membrane has uneven surface, it is diffuse reflection when the light shines on it, so the screen will not be too harsh but soft with low light transmission.
- Q:How long can a mobile phone film use
- It depends on time you use your phone, if you play the game in a long time everyday, mobile phone film must have a short longevity. In general, a film can use two or three years. And, if you protect it well, you can use it until you do not want to use it.
- Q:What is the warm reflective film made from?
- Warm reflective film on the market can be divided into three categories according to material: One is basilemma and the others are fabric basilemma and insulation material composite basilemma. The paper basilemma can also be divided into two categories. One is the paper basilemma (not reinforced). Another is the reinforced paper basilemma (commonly known as reinforced aluminum foil). The paper basilemma is made by the means of curtain coating of paper and film in high temperature. It has the advantages of high brightness, smoothness, good adhesion, clear printing that is non-easy falling out. And it wouldn't roll. But its tensile strength is lower than the reinforced one. The reinforced basilemma is made by different manufacturing technique and equipment. It is made by the means of curtain coating followed by a process to sandwich a layer of fiberglass between two membranes. It has the advantages of high tensile strength. But also due to the production process, it has a bad printing effect and is easy to roll. Besides, The paper basilemma can be divided into two categories, namely the wood pulp paper and the straw pulp paper. There exists a large cost gap between them.
- Q:What are the functions of reflective membranes?
- Safety products made of reflective materials have a strong reflective effect in a certain light source, and provide the most effective and reliable security for pedestrians at night or night workers. Reflective membrane is a PVC membrane with a special structure that can reflect the light back to the light source in used of optical principles. It is composed of thin layer, glass beads layer, focus layer, reflecting layer, adhesive layer and stripping layer with good weather resistance performance.
- Q:High density polyethylene root-resistant geomembrane
- High density polyvinyl chloride root puncture resistant geomembrane, aslo called high density PVC root resistant membrane, is a kind of geomembrane which has good seepage-proof effect and good resistance to puncture as well. High density PVC root resistant membrane, with good flexibility and puncture resistance, can be used in a variety of complex construction environment. The width of common High density PVC root resistant membrane in current market is 2m. You can use dedicated welding machine when paving a large area of high density PVC root resistant membrane. Besides, the high density polyethylene root puncture resistant geomembrane in market is also called HDPE root resistant membrane which has better anti-seepage effect, anti-puncture ability and longer service life than High density polyvinyl chloride root puncture resistant geomembrane. It is also cheaper than High density polyvinyl chloride root puncture resistant geomembrane so it can completely replace High density polyvinyl chloride root puncture resistant geomembrane. The width of high density polyethylene root acupuncture resistant geomembrane in current market is 8m, which the common width is 6m. Compared with High density polyvinyl chloride root puncture resistant geomembrane, it can reduce welding cost in construction greatly.
- Q:Can geomembrane be used in building a methane tank?
- Nobody will adopt this stupid method. You can ask a qualified worker for help If you do not know how to do it.
- Q:how does the switching power thick film circuit work?
- 1.STR-53041 is a thick film ICs for TV power switching circuit consists of two NPN type transistor and a PNP transistor and a regulator and a number of resistors in five ends .STR-53041 devices .3 termination power input terminal 4 of the common ground terminal, the second end of the feedback terminal, one end of the sampling signal input, the TV using the 5 'end idle. 2.TR1 oscillation transistor is NPN type, it and P B winding and a feedback winding of the transformer T form a feedback oscillator circuit .TR2 are NPN type transistor and the regulator ZD constitute sampling comparison circuit provided by the comparison voltage .TR3 transformer T D windings are PNP transistors constituting the sampling signal current amplifier circuit for driving the oscillating tube, perform pulse width modulation circuit output voltage amplitude stability. 3.STR53041 natural oscillation frequency is lower than the TV line frequency, it is subject to the line frequency flyback transformer FBT came forward driving pulse synchronization work 15.75KH. to eliminate the image appears horizontal frequency interference.
- Q:What is electrothermal membrane technology?
- The electrothermal film is a electric heating element directly that converts electrical energy to heat the heating element, and it is one member in the heated product like the electric heating tube, electric heating rod, electric heating plate, electric heater, electric cooker, induction cooker and so on. But the difference is that the electric heating film in China is still a relatively new product categories, whose application history is only a short span of ten years, so few people konw about the application of electrothermal film widely. So it is difficult to look up the definition of electrothermal film in textbook and dictionary;. The domestic and foreign textbooks and dictionaries are very difficult to find the exact definition of electrothermal film, The definition of electrothermal film in China is based on promotional materials of electrothermal film, mainly include electrothermal film printed by ink, such as: Electrothermal film is a kind of half-transparent polyester film that can heat after electrified; processed and hot-pressed with electrified special ink and metal carrier in translucent polyester film made from special conductive ink, the metal carrier asamen processing, hot pressing in insulating polyester film room. Former Ministry of construction named its project report for standard of construction industry as Low temperature radiation polyester electrothermal film; Obviously, it was refering to carbon based printing ink electric heating film. The name was later changed into "low temperature radiation polyester electric heating film". In recent years, with the application of all kinds of electric heating film technology in large-scale production and market, people gradually understand various types of electric heating film. How to accurately define electrothermal film has become one of the widespread concern and discussion in the industry.
- Q:How to calculate the power consumption of the electric heating film?
- The operating power P=UI, depending on the voltage and resistance of the equipment. The resistance value of the electrothermal membrane can be measured with an ohmmeter from the end of the thermostat. Generally speaking, the actual resistance is with a little diffrence with the square power and product of area. Therefore, after the acual pavement of the electric heating film has been done, the construction staff will give the actual pavement power. Due to the fluctuation of voltage during the operation of the equipment, it will also cause changes in the power of the electric heating film, if the voltage is low, the power will be small, the heating time will be extended.
