Huangchuan County new plastic welding equipment / ultrasonic plastic welding machine [Today / Information] 2022 has been updated such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito pats, etc. Double-head ultrasonic plastic welding machine, can give full play to its welding effect when welding hard plastic materials, ultrasonic welding machine, special scope: used for car body plastic parts, car doors, car instruments, headlamps, mirrors, sunshades, interior decoration, filters, plastic electronic products: prepaid water meters, electricity meters, communication equipment, cordless phones, mobile phone accessories.
Of course, the work of solar greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.
Of course, the cooling work of the greenhouse in summer can not rely entirely on the greenhouse insulation quilt, but also should take some other measures accordingly. Can cooperate with enhanced ventilation to cool down, but it should be noted that it is best to set up a wind shield in the tuyere to avoid the cold wind blowing directly on vegetable and fruit noodles; you can also use a sunshade net to cool down, and the shading rate of the shading net can be selected according to your needs. The advantage of shading net is that it can not only prevent sunburn vegetables, but also allow part of the light to illuminate the interior of the greenhouse, ensuring the photosynthesis of vegetable leaves; you can also take spray cooling methods.
Professionals said that audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus playing the role of energy saving and consumption reduction. 5. Heat preservation and heat relief: electric curtains can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
Simple installation-free car sunshade, directly like an umbrella for 3 seconds, can fully block the car windshield, so that there is no longer worry about sunlight, even if you park in the open air, you are not afraid of the high temperature in the car, and by comparison, the temperature of the car installed with this sunshade can drop by about 60% after exposure, which is too comfortable and useful.
2. Thermal commonality first of all, it refers to the connection between different kinds of metals or between metals and non-metals by heating metals and manipulating the principle of thermal expansion or thermal melting. For example: aluminum sheet for copper core of computer radiator, embedded welding of horn net, composite of steel-plastic pipe, sealing of aluminum foil (toothpaste skin), motor rotor, electric heating pipe sealing and so on. 4. Automotive supplies industry: the automotive supplies industry continues to develop new cars and adopt different car interior accessories, the use of high packaging equipment technology is mainly used for car sunshade panels, car door panels, car airbags, car floor mats, car anti-skid mats, automobile leather pressing, and so on.
Felt quilt in order to achieve a good thermal insulation effect, can be covered with a layer of non-woven fabric or sunshade net and other thermal insulation materials, in the presence of very low temperature weather, you can choose to add “shed” to heat preservation. Although the work of heat preservation in cloudy days is important, it should not be blind and needs reasonable regulation and control. In a snowy day, the night temperature is easy to rebound, the plant accumulates less photosynthetic nutrition during the day, but consumes more at night, so it is easy to grow poorly. Therefore, it is very important to regulate the night temperature in overcast, rainy and snowy weather.
