Therefore, broken bridge aluminum doors and windows are widely used in office, factory, refrigeration, laboratory, instrumentation, factory buildings and other general doors and windows (heat insulated windows, dry windows and open windows are widely used). Factory doors and windows use steel doors or wooden doors as one of the main materials for fixing doors and windows. People come into contact with sawed doors and sawed doors. Saw door is the abbreviation of building door and window, and the general name of saw door is saw door head. Saw door is an important form used as window in ancient times, which is mainly used to hide the thermal insulation of large sunshade, TV cabinet and door.
The evaporation of water in the plastic film prevents the large amount of air humidity in the shed after watering. Select natural materials for moisture absorption, such as rice straw, wheat straw, quicklime and other materials to adsorb water vapor or fog between rows, and select insulation curtain materials with good moisture permeability and moisture absorption, such as non-woven cloth can condense dew on the inner surface, and prevent dew from falling on the plant. Thus reduce the air humidity, ploughing dehumidification by cutting off soil capillaries, can prevent soil capillary water rising to the surface, can avoid a large number of soil moisture evaporation, with the increase of summer temperature. How to properly cool the greenhouse has become an important work of daily management, the following we will introduce the following six measures, 1, external sunshade system. Is to keep the excess sunlight out of the greenhouse. Form shade to protect the crops in the greenhouse.
In the part of storage space, both cars are fully equipped. In addition to conventional front and rear door slots, glove boxes, armboxes, storage compartments and cup holders under the center console, a lot of hidden spaces are optimized, such as the storage space above and below the sub dashboard of BYD Song PLUSDM-i, under the left air conditioning controller and inside the sunshade. The Harvard second-generation dog PHEV is also equipped with more user-friendly storage space, such as four-door cup holder straps, storage slot above the glove box, upper and lower two-story temperature control armrest and multi-stage lifting cup holder.
The interior accessories of the car mainly include steering wheel, dashboard, seat, seat belt, ceiling, door decoration, floor decoration, inner wall decoration, air conditioning system outlet, door lock, door hinge, glass elevator, various seals, wind window wiper, window washer, sunshade, rearview mirror, handle, cigarette lighter, ash box, radio antenna and so on.
The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
