Inorganic FRP materials and greenhouse frame

Inorganic glass fiber reinforced plastic material and greenhouse frame I. Project introduction Polyester glass fiber reinforced plastic material is the product of the scientific and technological revolution, is a rookie of the material revolution, since its appearance in just a few decades, with its light weight, high strength, waterproof, durable Such advantages have been applied to various fields in the world and modern products such as aircrafts, spacecrafts, boats, cars, houses, bathtubs, etc. have been manufactured. The inorganic FRP material developed by the patent is more attractive because it has the advantages of rich source of raw materials, low cost, simple production process, waterproof and igniting, and its products can replace traditional materials and polyester fiberglass in a wide range. Materials, to be developed in a wide range of applications, greenhouse frame is one of its products to be developed. In recent years, with the adjustment of the rural industrial structure, the solar greenhouses in protected areas have rapidly developed in the vast rural areas. It is not only used for the cultivation of vegetables, flowers, fruit trees, and edible fungi, but also for aquatic products, breeding of livestock and poultry, and rice cultivating. In the past few years, China's rural greenhouse frame materials mainly bamboo and steel. Steel frame materials are mostly welded by steel pipes. They are easy to use and have a solid structure. However, their cost is high. Generally, they cost more than 50,000 yuan per mu, which is easy to corrode. Rust is unfavorable to flowers, vegetables, fruit trees and other crops. The application is restricted; bamboo and wood structure greenhouses are cheap, the construction cost per mu is about 5,000 yuan, and the investment is less. It is rapidly promoted in the vast rural areas, but the bamboo and wood structure is low and backward, the top pole is dense, the operation is inconvenient, and the wind and pressure resists. Weak capacity, short service life, generally used for one to two years, belong to the initial stage of development of greenhouses, can not meet the needs of modern agricultural development; steel or aluminum alloy material frame is a high-grade products, the high cost per million mu is million, general people It is difficult to accept; in the past few years, there have been new types of composite materials in greenhouses that are hand-made with talcum powder, gypsum, glass fiber cloth and other materials on the market. However, the practice has proved that its solidity and service life are not ideal, and the Approved by farmers' friends. Therefore, the market urgently needs to develop and popularize new types of greenhouse frame materials that can replace bamboo and steel and that are widely accepted by farmers. The inorganic glass fiber reinforced plastic frame material has the characteristics of rich source of raw materials, low price, waterproof and igniting, stable quality, resistance to wind and pressure, reasonable structure, convenient installation, long use time and no pollution, and this is also the development of the later shed frame material. Inevitably, there is a bright future for the development of inorganic glass fiber reinforced plastic awning skeletons with significant social and economic benefits. The patents for inorganic FRP materials and greenhouse production technology were officially accepted by the State Intellectual Property Office in May 2003 (acceptance number 03136971-5) and were published in the Chinese Patent Gazette on April 14, 2004, and were listed as national Focus on supporting promotion projects. The patented technology produces inorganic glass fiber reinforced plastic skeletons with mechanized production, 4x6 cm section (section size and rod length can be randomly adjusted), smooth surface, protection of agricultural film, quality like stone, nature like steel, good Toughness and flexural resistance, no corrosion, no aging, snow pressure resistance, moisture resistance, life expectancy of up to 30 years, less or no roof pillars can be installed in the shed, skeleton curvature and length can be used with the terrain size, shed type Reasonable structure choice, suitable for different specifications of greenhouses and simple sheds, single-span greenhouse spans up to 5-12 meters, simple shed spans up to 5--20 meters, can be a multi-span shed, equipped with galvanized buckles It is easy to install and costs about 3,000 yuan per hectare of scaffolding. It is an ideal choice for farmers. At present, the low-volume production of inorganic glass fiber reinforced plastic framework has been promoted locally in Xiangyang, and has been recognized by experts and users. II. Economic and Social Benefits After the project is implemented, economic, social and environmental benefits are significant. The annual demand for domestic greenhouse frame market is 50 million mu. The investment is to build a greenhouse with an inorganic glass fiber reinforced plastic skeleton, which can increase income by 10,000 yuan per year. (Only for planting vegetables, if there is a higher efficiency of greenhouses for other uses, the year of flowers The income can reach more than 100,000 yuan), the life expectancy is calculated according to 10 years (conservative), and its social and economic benefits are considerable. At the same time, it can save a lot of bamboo and steel resources for the country. Third, the establishment of plant efficiency The investment scale can be as large or small as the market demand. The cost of an inorganic glass fiber reinforced plastic skeleton per mu is 3,000 yuan. The market price is 4,500 yuan and the profit and tax is 1,500 yuan. 1. Medium-sized factory (an annual output of 5,000 hectares of scaffolds to meet general municipal requirements): 1 million yuan of investment, including 500,000 yuan for equipment investment, 500,000 yuan for working capital, 60 workers, and 20 acres of scaffolding for the year 250 days of production, an annual output value of 30 million yuan, a profit and tax of 11.25 million yuan. 2. Small-scale plants (an annual output of 1,000 mu of scaffolds to meet the requirements of the county level): 200,000 yuan of investment, including equipment investment of 100,000 yuan, current capital of 100,000 yuan, 15 workers, and 4 mu of scaffolding. Annual production of 250 days, annual output value of 6 million yuan, creating profits and taxes of 2.25 million yuan. IV. Cooperation Form 1. Technology Transfer: (1) Exclusive transfer fee at home and abroad: 1.5 million yuan (2) Exclusive transfer fee at provincial level: 500,000 yuan (3) Exclusive transfer fee at municipal level: 250,000 yuan (4) Ordinary technology Transfer fee: 200,000 yuan 2. Technology shares: (negotiable) 3. Joint venture: (negotiable) V. Patent owner Zhang Shaoliang, male, born in 1969, is a high-tech development zone worker in Fuyang City, Henan Province, graduated from Henan in 1991. Provincial Department of Science and Technology, Department of Engineering. He is currently the engineer and chairman and general manager of Sunlight Wenpeng Engineering Co., Ltd. in Liyang City, Henan Province. It is mainly engaged in research and development and promotion of greenhouse technology.
