As a new type of packaging material, plastic has been widely used in the field of packaging. For example, all kinds of hollow containers, injection molding containers, packaging films, woven bags, styrofoam straps, packing straps, etc. In terms of transport, the plastic used in vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle or per-vessel basis. Varieties include fuel tank bumper, sunshade seat, door handle, steering wheel, dashboard and so on The commonly used materials in agriculture are film, pipe, plate, rope, woven bag and so on. Plastic granule manufacturers introduce the packaging for plastic greenhouse, crop fertilizer and so on, plastic pipes for farmland and water conservancy projects, farmhouse construction, animal husbandry protection, agricultural machinery and utensils, fishing net culture, floating, etc.

In terms of temperature management, the early growth stage of spring cauliflower cultivation was in the low temperature season, and the growth was small, while the plant size of broccoli was closely related to the flower head yield, and the temperature increased rapidly in the later growth stage, which was disadvantageous to the flower bud differentiation and flower ball formation of broccoli. Therefore, in the field management, it is required to do a good job of heat preservation in the early stage of growth to prevent freezing. Those cultivated in greenhouse should be closed in time to keep warm, those cultivated in open field should be trenched and drained as soon as possible to prevent freezing, and the remedial method of covering the floating surface of sunshade net should be adopted in case of sudden frost or freezing weather. In the later stage of growth, after the temperature rises in April, the protected cultivation should do a good job of ventilation and cooling in time, and the flower heads should be harvested in time after maturity.

Nanshan reliable steam consumption: the use of ultra-high temperature steam to eliminate bacteria, remove odors and long-term bacteriostasis: the interior surface of the whole machine is sprayed with green long-term bacteriostatic agent, your health, we care. After preparing the detergent, we can just dip the towel in the detergent to scrub the sunshade. I would also like to remind you that you should wipe along the umbrella frame longitudinally and in the same direction, not vertically and horizontally.

EPP (polypropylene) foam is a foam material formed by foaming with polypropylene resin as the matrix. It not only has high heat resistance, high impact energy absorption capacity, good resilience and thermoformability, but also can be recycled. It has been widely used in automobile interior and exterior decoration parts, such as bumper energy absorber, sunshade, tool box and so on.

There are two kinds of interior design, high-end version is a common conjoined screen design, the back has a through-style air conditioning tuyere, so that the entire center console is extremely flattened. The part of the air-conditioning system uses a physical button panel, which is arranged in front of the sub-dashboard, and the flight-style electronic file handle is also frequently seen in the design of independent brand models. The latest spy photo also reveals a low-profile version, which may be mainly designed for the needs of the travel market. The difference is mainly in the upper part of the central console, where the dashboard changes into a traditional sunshade structure, but still uses a full LCD screen configuration. The multimedia system is an exposed cavity that can be equipped with devices such as a simple radio multimedia player or a taximeter.

First of all, car shading can effectively reduce the temperature inside the car. Sunshade is a combination of multi-layer bubble film and aluminum foil, which belongs to a kind of plastic products. Aluminum foil has the ability to reflect light, thus reducing thermal radiation and low thermal radiation conductivity. When the sun shines on the sunshade, some of the heat will be blocked and the ultraviolet light will be reflected by the aluminum foil.

More orange decorations are found on seat belts and sunshades, not to mention the steering wheel and center console. The dash becomes a little different-wood.

Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
