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.
1. Keep warm and protect against cold. The cold prevention work should not be relaxed, and the ditches should be cleared around the vegetable fields to ensure the smooth flow of drainage and irrigation, seal and fill the holes and cracks in the greenhouse film, and according to the change of air temperature, the small arch shed can be covered with sunshade net, straw curtain or non-woven fabric at night. increase heat preservation capacity.
Such as sunshade panels, exterior insulation panels and local areas where the temperature between the doors is easy to rise. In the field of temperature, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam, for example, in addition to light weight, because polypropylene foam has higher heat resistance, epp materials are in higher demand. Why is the substitution of epp materials so great in the automotive field?
Although the holy dashboard coating can prevent ultraviolet rays, in order to better prevent the dashboard from cracking and aging by the sun, especially for the car owner parked outside, it is necessary to use a sunshade to protect the device in the car, which is not only beneficial to the dashboard, but also prevents the cushion from whitening and discoloring. Drop a drop of oil on the ignition switch key and insert the key into the ignition switch lock and turn it several times to lubricate the lock mechanism.
Why use sunshade? The main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. Among them, there are many different types of products. Second, in terms of service life, the steel drag chain is generally no less than 10,000 times, which is also a variety of technical advantages that can really be brought about by such a rotation speed. after updating such characteristics, we will be able to constantly grasp such technical characteristics, and then form the key to be more convenient to use in machinery. In order to fully grasp such technical advantages, this is * the main reference. After the continuous improvement of service life, gradually will be in this point of view, or more important, to be able to grasp such a technical advantage, is * the key.
Car interior accessories include dashboard, door interior panel, steering wheel, seat, roof, floor mat, sunshade, storage box, ashtray, etc., as well as some ancillary equipment such as audio, air conditioning, communications, television, lighting, etc.; car exterior accessories, including bumper, radiator grille, side anti-collision bar, rear deflector, all kinds of car lamps and lanterns, vehicle glass, and car body accessories such as door handles, wipers, door locks, etc. The functions, shapes and structures of these internal and external decoration components are different, and they are organically combined to form a unified, coordinated and beautiful internal and external decoration system. The materials used in many of these parts are plastic materials. at present, the plastic consumption of many cars in the world has exceeded 120 kg / car, and some models are even higher. The plastic consumption of German Mercedes-Benz luxury cars has reached 150 kg / car. The plastic consumption of some cars in China has also reached 90 kg per car. Figure. 1 shows the current situation of the application of automotive interior decoration materials.
Winter tea is dormant, generally low temperature overcast and rain has a limited impact on tea, but if it encounters wind and freezing or extreme low temperature, it will affect tea tree winter and spring tea production in the coming year. One is to cover and keep warm. Can be in the cold air before the tea cover surface covered with rice (miscellaneous) grass, sunshade net and so on. The second is to build barriers and guard against the wind. For the land easily affected by wind freezing, sunshade nets and other materials should be used in advance to establish wind barriers in the windward, which is higher than the 20cm of tea canopy and tilted to the direction of tea trees. The third is to restore the tree situation in time. For the heavily frozen tea garden, it is appropriate to make trees after the beginning of spring, rather than deep pruning and pruning, and strengthen the management of spring tea fertility.
Company profile: Beijing Hanyi Automobile Accessories Co., Ltd. (hereinafter referred to as Hanyi), located in Shunyi District, is a joint stock joint venture co., Ltd., which integrates strategic investment and management, and is jointly invested by China and South Korea. The company was founded on December 2, 2003 with a registered capital of 10.2 million US dollars, mainly in the development and manufacture of car door guard panels, inner roof panels, dashboards, seats, package plates, sunshades, carpets, rear box panels and other automobile accessories, and sell self-produced products and provide technical services for self-produced products. At present, it mainly provides services for Beijing Hyundai, Beijing Automobile, Beijing Mercedes-Benz and Futian. We are now looking for the following personnel:
Raise the level of mechanized production and liberate labor productivity. First of all, from the environmental control system of multi-span greenhouse, electric sunshade, electric film (window opening) ventilation, electric thermal insulation quilt, electric fan water curtain cooling have been realized, and the environmental control ability of greenhouse is more stable and reasonable. work efficiency is higher, do not need manual operation, just press the switch of the distribution cabinet. Looking at the agricultural production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic sprinkler irrigation, integrated water and fertilizer machine, automatic seeder, and even Internet of things control software are now very common systems. greatly improve the production efficiency and achieve precision irrigation and fertilization, water-saving and fertilizer-saving, soilless cultivation and other protection of soil from pollution.
