how to make a 99% filter melt-blow? Methods to improve filtration efficiencyA. Increase the hot air flow or temperature (increase the fiber fineness, reduce the porosity, improve the catching ability, but increase the resistance);B. Increase electrostatic voltage (current) (polarization fiber, increase electrostatic field energy of fiber, improve its adsorption capacity);C. Add powder or other electrets to the raw material (improve the fiber's electric receiving capacity and storage time, so that the fiber can carry more charge and charge time);D. Increase the suction at the bottom of the net (increase the density of the fiber, improve the capturing ability of the fiber). The gram weight is obvious and is not commonly used);E. Reduce the yield appropriately (under the same process, the extrusion quantity becomes smaller, the fiber becomes thinner, and the resistance increases);F. Increase the working temperature of die head (die tip) and other areas (melt fluidity becomes better, fiber becomes thinner);G. Increase the ambient temperature of spinning (when the fiber becomes thin, the resistance increases significantly and other physical indexes decrease when the room temperature increases);H. Appropriately increase the amount of powder.contact us for static charging for the melt-blown cloth, or buy melt-blown cloth directly from us via sales@innovation-electronic.com http://www.innovation-groups.com/pid18278580/VCM60-60kv-2-5mA-Static-Charging-Equipment-for-1600mm-melt-blown-cloth-machine.htm

The static electricity generator has over-current and short-circuit protection functions. The discharge to the ground is “not ignited”, and the ground or the workpiece is too close. The worker accidentally touches the automatic shutdown system and has a high safety factor. Electrostatic generators mainly generate static electricity. The output is usually single polarity. For positive or negative polarity, the output voltage can be adjusted. It is usually used in scientific research, electrostatic applications such as electrostatic dust removal, electrostatic spraying, and electrostatic field generation for biological effects research. And other places where static electricity is to be applied. Application:(In mold labelling(IML)、Automatic film change、Cast seam、Electrostatic pile paper、Electrostatic recombination、Edge banding of heat shrinkable packaging machine、take-up and exhaust of bag-making machine、static insert card、static cooling of Rotary press、static ink of gravure press、static laid paper of overlaying production line、static film (paper) pasting for shearing machine、static adsorption location of glass sheet； The electrostatic discharge generator is mainly applied to the anti-human metal model electrostatic discharge test of system-level electronic equipment such as mobile phones and computers. Includes an electrostatic generator and an electrostatic discharge gun. The output of the electrostatic generator in the ESD generator is positive and negative, and some are positive and negative, and their voltage bipolar high-precision output is continuously adjustable. It is also suitable for more application areas and requirements for new standards in the future. Therefore, the electrostatic discharge generator can be used for electrostatic discharge testing of most electrical and electronic equipment.In mold labelling(IML)：Electrostatic adsorption： The static electricity generated by the electrostatic generator is applied to the object to be adsorbed, and the object is immediately electrostatically charged and adsorbed on the object, so that the original unevenness, such as non-woven fabric, paper, etc. It is flatly adsorbed on metal plates, wood boards, etc. for the next step. This method is widely used in steel production, wood production and mold industry.

The application of industry counting scale in precision component industry electronic counting scale is a perfect embodiment of counting/weight check in enterprise measurement.It USES a high-precision strain weighing sensor, coordinates with IN420 counting indicator optimization program design, has high weighing accuracy (degree = 100,000), small repeatability error, and quick and accurate display data.Using comprehensive functions: LED have adapted to all kinds of weighing, keyboard voice prompt, weight, counting, accurate sampling and single memory (10), accumulated the quantity/weight, weight/quantity alarm, alarm state selection, weight display unit selected kg (kg/LBS lb), AC AC/DC DC power supply, equipped with RS232/ RS485 serial data output (can connect the computer and printer) serial port. Application of counting electronic scales in precision components industry:The raw material warehouse of an auto parts manufacturing company has long been manually counting the number of components, among which the vibration damping spring (2.3g) with a light weight is time-consuming and laborious, which cannot meet the enterprise's measurement requirements.THE industry counting sale (can be 10kg 0.1g, 60kg/1g, 100kg/1g) counting balance was adopted to improve the counting accuracy and working efficiency. The operation method is as follows:1 count scale is preheated for 10 minutes after starting up (in order to make the electronic components of the electronic balance circuit system of [industrial electrical network-cnelc] circuit system reach the thermal stability state),2 single resampling: manually count 100 single weight same components (the more the better, note: must not count wrong!!!!!!), and then put the number of components in the center of the said plate, using digital key input number values (e.g., 100), and then press a single set, then counting scale single window display this batch components of a single value, the display of the single weight value is very important, because it is the average of 100 component, this is after the precise number of a benchmark.3. Single weight storage: press the single weight setting button for about 2 seconds and enter 0-9 arbitrary number keys. At this time, the single weight has been stored in the electronic scale (no data will be lost due to normal shutdown).That way you can count and weigh.4. Single reset: it can be called at any time when the machine is rebooted (press the corresponding number key, then double click the single reset key to adjust the stored single weight data), and it can be counted and weighed at any time.5. Normal counting: take out some unknown number of similar components to prevent them from being placed on the scale plate at will. The electronic scale rapidly displays the calculation results, and then manually verifies the accuracy of the results

Digital load cell system is a new type of electronic weighing technology developed on the basis of traditional resistance strain sensor combined with modern microelectronics technology and microcomputer technology integration. It is composed of analog sensors (resistance strain type) and digital conversion module two parts. Digital modules aremade from highly integrated electronic circuits fabricated using SMT surfacemount technology. They include amplifiers, A / D converters, CPUs, memory,interface circuits (RS485) and digital temperature sensors etc. It has the following features:1,the digital sensor uses integrated A / D converter circuit, digital signal transmission and digital filtering technology, the sensor signal transmission distance is far, up to 1200m, anti-interference ability is good. The transmission distance of analog signals within the digital sensor is very short, while the sensor housing (elastomer) itself is a good shield, these two features alone determine the advantages of its anti-jamming capability, greatly improving the stability of the sensor.2, good confidentiality, anti-cheating function, can effectively prevent remote control cheating.once found, it will automatically take the error alarm, effectively protect the data security and accuracy. The analog sensor truck scale installed cheat is common, because cheaters’size is small and the installation is extremely simple Therefore it is not easy to be found that caused a great riskof the safety of measurement data. The digital transformation of the weighing instrument can make the safety of the measurement data well protected, so as to better safeguard the economic interests of the company.3,As the digital sensor with automatic acquisition pretreatment, storage and memory functions, and has a unique mark, more than one sensor in parallel group scale can check the status of each sensor to make diagnosis fault easy. When using the analog sensor, once the device working status is unstable, it is difficult to determine which sensor has a problem, only by opening the junctionbox to check the signal of each sensor, use exclusion to check one by one. To find there The problem sensor needs to spend a lot of time, a lot of manpower,material and financial resources. It fully proved the superiority of the digital sensor and its important role in the actual production.
