1. Before the construction of the thermal insulation project in the building, the door and window frames on the walls that need to be insulated shall be installed. Pipe cards, pendants and other pre-embedded parts needed in plumbing and decoration projects should be set aside or finished. The hidden pipelines and junction boxes of electrical engineering should be buried, and the threading line of hidden pipelines should be completed. 2. Sealing series: carbon packing, tetrafluoroplastic gasket, plate, graphite winding gasket, oil-resistant asbestos board, high-pressure asbestos board, high-pressure asbestos gasket and other products.
The cab. The flat head can be turned over, the torsion bar type overturning mechanism, the driver seat, the middle seat and the helper seat are arranged in the front row of the driving room. The driver seat can be adjusted back and forth, and the seat back angle can also be adjusted. There are berths in the back row with insulated carpets, sundries, quartz clock, cigarette lighter, receiver, sunshade, inner rearview mirror and curtain frame. Both doors are equipped with locks, door glass can be raised and lowered, triangular window and rear window glass can be opened. The front window is equipped with an electric wiper and washer, and the door is equipped with an external rearview mirror. There is instant wind, air conditioning optional.
4. The biggest characteristics of aluminum wood sunshine house are heat preservation, energy saving and sand resistance. The aluminum-clad wood doors and windows are coated with aluminum alloy in addition to the solid wood, which makes the doors and windows more airtight and can effectively prevent the attack of wind and sand. With aluminum alloy broken bridge material as the main frame, through buckle embedded in natural pure wood, the appearance is modern, atmospheric, sturdy, exquisite, light and elegant, aluminum doors and windows meet the warm and harmonious texture requirements of modern residential design, with gorgeous colors on the outside, natural luxuriant interior decoration, calm and introverted multiple advantages. With light and beautiful appearance and excellent wind pressure resistance, watertightness, air tightness and heat protection, sound insulation, environmental protection performance. When the heat is unbearable, it can prevent the dry heat outside and reduce the loss of indoor air-conditioning; it will not freeze and dew in the cold winter, and it can keep the noise out of the window.
The foaming pores are closed and the water absorption is very small. The design of steel jacket steel composite thermal insulation steel pipe is relatively simple. It consists of four parts, from the inside to the outside. The external sliding thermal insulation structure of polyurethane foamed thermal insulation steel pipe is composed of steel pipe, glass wool insulation layer and aluminum foil reflection layer, stainless steel fastening belt, sliding guide frame, air insulation layer, external protection pipe and external anti-corrosion layer. The method of polyurethane foamed thermal insulation steel pipe is only suitable for 3mm lower than ordinary casing insulation layer. Polyurethane thermal insulation directly buried pipe joint is a seemingly simple, necessary engineering technology, we do not have telephone guidance and construction personnel, send professional and technical personnel to the effect of on-site guidance. Polyurethane insulation pipe, full name: high-density polyethylene plastic external protection polyurethane foam prefabricated directly buried insulation pipe, by the transport medium of the working steel pipe, polyurethane insulation layer, polyethylene plastic external protection pipe, through the equipment in turn to the outside.
The density of magnesium is about 1 beat 4 of steel, and that of aluminum is about 1 beat 3 of steel, so using light alloy materials such as magnesium and aluminum alloy to replace steel is the most widely used measure at present. In January 2017, the Ministry of Industry and Information Technology, together with the National Development and Reform Commission, the Ministry of Science and Technology, and the Ministry of Finance, issued a Guide to the Development of New Materials Industry. It is proposed to speed up the application of magnesium alloy and rare earth magnesium (aluminum) alloy in automotive dashboard and seat frame, steering wheel core, wheel hub and other fields to support the development of automobile lightweight. In April 2017, the Ministry of Industry and Information Technology, together with the National Development and Reform Commission and the Ministry of Science and Technology, jointly issued the medium-and long-term Development Plan of the Automotive Industry, proposing to develop advanced automotive materials and manufacturing equipment to speed up the application of magnesium alloys and rare earth magnesium (aluminum) alloys. The support of the above industrial policy has strongly accelerated the application of magnesium and aluminum alloy in the field of automobile lightweight, and the application scene is constantly expanding.
