In the severe winter weather, the small arch shed in the greenhouse should be covered with a layer of straw buns or covered with quilts to keep warm, and then covered with a layer of film. Add windbreak and anti-freezing barrier. The combination of straw and old film into a cold wall, placed in the north of the vegetable greenhouse, as a wind barrier, can reduce the harm of cold current. When the temperature in the greenhouse is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. When heating, open fire can not be used to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside. Focus on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings that are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent frost damage or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed to make the plants see as much light as possible.
According to the different use characteristics of famous plastics, the production of food plastic products in Quzhou City is usually divided into three types: general plastics, engineering plastics and special plastics. First, general-purpose plastics generally refer to plastics with large production capacity, good formability, cheap price and wide use. The reason of shrinking pit is the same as insufficient filling, which can be solved by excess filling in principle, but there will be stress. Attention should be paid to uniform wall thickness in design, and the wall thickness of reinforced ribs and convex columns should be reduced as much as possible. The treatment of the overflow edge should mainly focus on the improvement of the die. On the other hand, in the forming conditions, we can start to reduce the liquidity. The representative parts on the car are dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar decoration, front roof lining, window frame, ceiling and side roof frame decoration, door liner, sunshade board, rear roof frame decoration and so on.
In a typical dialysis clinic, there is no guarantee that all the spaces frequently used by patient stations or staff will have natural lighting. The direction of the glass usually causes glare and may not be consistent with the comfort and safety of the patient. The project consists of two indoor courtyards that provide fair access to daylight throughout the clinic, while allowing other use spaces, such as offices, conference rooms, staff lounges and private family training rooms, to benefit from outdoor vision and adequate natural light. In order to reduce the increase in glare and solar heat, the design gives priority to north-south glass, using building mass and sunshades and custom perforated vertical screens to regulate direct sunlight in the south.
The material is made of ecological wood, which has the advantages of no pollution and so on. Use healthily. Can be ready for use, first, exterior wall decoration, applied to external wall decoration products are mainly Great Wall board, outdoor floor, square wood, sunshade board, stacked board five series, mainly used in a variety of outdoor wallboard drivers, external wall decoration products are mostly hollow multi-cavity structure, can effectively achieve the role of thermal insulation and sound insulation, its excellent anti-fading, weather resistance and anti-aging products can be used for more than 20 years. In line with energy-saving and environmental protection building exterior wall standards, second, interior decoration, interior decoration products in addition to ceilings, blinds, triangles are available, exterior wall decoration products can be used in indoor TV background wall, bedside background wall, wall skirt, shutter, bathroom wall and floor. Balcony decoration, and smallpox decoration, package columns and other styling use.
In response to typhoon days, Ding Dong also made a series of preparatory actions in the front warehouse, such as strengthening the sunshade, preparing emergency equipment such as generators and pumps, flexibly adjusting the transport capacity of various stations, and doing a good job in safety training for front-line staff to ensure that vehicles, batteries, raincoats, mobile phone waterproof bags and other equipment are well equipped, and cold repellents such as towels, hot water and ginger tea are prepared to prevent workers from catching cold. All front positions ensure that the work is carried out in an orderly manner on the basis of safety.
Car umbrellas are useful. According to the sunscreen principle and the shape of the car, the car sunshade covers from the front windshield to the rear windshield. The sun umbrella which can effectively reduce the temperature rise in the car when parking at high temperature is called car sunshade.
Some time ago, a Jiangsu user bought a straw hat for my summer sunshade. After receiving the goods, he said that the thing you sent me was bad and asked for a refund. I saw the picture he sent showing the opening of the side line. We will check the goods one by one, it is impossible to have such a bad situation, it is useless for you to argue with him, and then say to him, how about I compensate you some money or give you another one? He said, then send me another one. When you send it, you must send it well. I said, of course, I am relieved to send you a good one. Then I sent him another one, thinking it was a thing of the past.
When selecting soft rubber joints, we should pay attention to selecting the appropriate product model. This can be considered from the aspects of the pressure of the wiring pipe, the interface mode, the material and the amount of repair, and the total number is selected according to the noise reduction offset. Pipe connectors that cause instantaneous working pressure to be higher than pressure should also be selected. (for example, when the pipe runs the transient working pressure > 1.0MPa, the 1.6MPa in the connector operation should be selected. When transient working pressure > 1.6MPa, 2.5MPa connector should be selected). When the pipe material is acid, alkali, oil, high temperature and other materials, the working pressure of the rubber soft joint should be one grade higher than the pipe pressure. Outdoor applications or pipes facing the sun and solar wind should be covered with sunshades to prohibit exposure, rain and wind erosion. The surface of the joint shall not be brushed with sand control and thermal insulation material. Due to the aging of rubber products, it should be inspected and replaced immediately.
