Strengthening and advancing the reform and construction of grass-roots agricultural technology extension system is a major event in agricultural development. In order to highlight key links, innovate service mechanisms, and vigorously promote the reform and construction of grass-roots agricultural technology extension system, preliminary results have been achieved. At present, the county has an agricultural technology promotion center, the township has an agricultural comprehensive service station, and the village has a science and technology demonstration household. The agricultural technology promotion network has been initially established and improved.
The reform and construction of grass-roots agro-technical extension system was taken as an important part of the overall rural reform, and overall planning was made. In 2002, in the reform of township institutions, Mengcheng County established a comprehensive service station for township and agriculture, with three rights: human, financial, and material rights. Decentralization to townships and townships, where people are arranged by townships to work in various centers, it is difficult to ensure that agricultural technicians devote themselves to agricultural technology extension services. At the same time, the knowledge of the grassroots agricultural technicians is aging, and personnel faults and work funds are difficult to guarantee. This has led to grassroots agro-technical popularization systems that have basically fallen into the predicament of “breaking the line and breaking the peopleâ€. The system is not smooth, the mechanism is not alive, the team is unstable and the guarantee is insufficient. The malpractices gradually emerged. In this context, the reform of grass-roots agricultural technology promotion system is imperative. Therefore, Mengcheng County insisted on the reform of grass-roots agricultural technology promotion system as a key task, unified deployment, overall planning and strong promotion.
Taking the reform of agricultural technology extension system as an important support for modern agricultural construction, strengthening grain production, and ensuring supply security, focusing on development, actively promoting the report of the party’s 17th National Congress, and General Secretary Hu’s visit to inspect the speech, both strengthening food production and ensuring supply Security is deployed as an important task. As a major agricultural county, Mengcheng County is an important grain production area and assumes the dual responsibility of ensuring food security and developing the regional economy. In practice, the grass-roots agricultural technology promotion system in Mengcheng County has not yet been able to meet the needs of modern agricultural development. Therefore, Mengcheng County insists on promoting the reform of grass-roots agro-technical extension system as an important strategic task for the development of modern agriculture and solid advancement of new rural construction, raising the support capacity for modern agricultural construction, relying on advances in agricultural science and technology, promoting the increase of farmers' income, and promoting the rural economy. Prosperity and promotion of Mengcheng's leap from big agricultural county to strong agricultural county. Taking the reform of the agricultural technology promotion system as an important means to strengthen the construction of the agricultural system team, based on itself, and actively promoting grass-roots agricultural technology extension agencies is a window for the agricultural system to serve the “three rural issues†and is also a bridge and tie for the relationship between the party and the masses. If grass-roots agricultural technology promotion fails to perform well and services cannot keep up, people will be dissatisfied and the image of the department will be affected. Before the reform, the development of grassroots agricultural technology extension agencies in Mengcheng County was unbalanced, the funding was short, the facilities were backward, the quality of personnel was uneven, and service awareness and service capacity were weak. Farmers had great opinions.
To change this situation, we must rely on deepening reforms to fundamentally strengthen the establishment of grass-roots agro-technical extension systems and improve the overall service level of the agricultural system. Therefore, in the reform, Mengcheng based on the promotion of public service functions, efforts to build grassroots agricultural technology promotion system into the main channel of agricultural socialization services, and build a strong technical fortress of agricultural systems to serve “three ruralâ€.
PP plastic, polypropylene, commonly known as "baijiao",Scientific name: polypropylene.
Description:
PP Plastic is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP Plastic don't have the problem of environmental stress cracking.Polypropylene (PP Plastic) is a semi-crystalline thermoplastic.PP Plastichas high impact resistance, strong mechanical properties, resistance to many organic solvents and acid and alkali corrosion.
PP Plastic is widely used in industry and is one of the most common polymer materials.
Australian COINS are also made of polypropylene.
Polypropylene bonding:
K-720 is suitable for polypropylene PP plastic adhesion, suitable for large area plate lamination, high transparency, suitable for PP adhesion PP, PP adhesive PC, PP adhesive ABS,PP adhesive PVC, PP adhesive acrylic, PP sticky metal, PP stick wood.
K-7007 adhesion performance is roughly the same as k-720, light yellow and more economical.
K-620 is adhesive small area polypropylene PP glue, must be used with the k-650 treatment agent, the instant positioning, the strength is high.
Advantages:
1. Low density;
2. Heat resistance ;
3. Non deformation;
4. High stiffness;
5. High surface strength;
6. Good chemical stability;
7. Nontoxic and safe.
Disadvantage:
The main disadvantage of the fault polypropylene is that the high temperature rigidity is not enough, and the low temperature is brittle.
Poor environmental tolerance, outdoor use, easy to turn yellow and brittle.
Tensile strength of anisotropy, the products are easy to deform, continuous use of low temperature, high creep performance, and long - term load.
Poor printing performance.
Application:
1,Valve part, drinking water and sewage water pipe,
2,Sealing element, spraying carrier,
3,Corrosion-resistant trough and barrel, industrial applications that have acid and alkali-resistant requirement; wastewater and gas discharge equipment for industrial purpose,
4,Scrubbing tower, clean room, semiconductor plant and other related industrial equipment and machinery, food machinery and chopping board,
5,Electroplating process, toy part
Combustion characteristics: PP Plastic easy to burn, polypropylene from continue to burn after the fire, with the top of the flame is yellow, the bottom made in blue, with a small amount of smoke generated, burning melt dripping, and oil.
Specification: the thickness of PP sheet material can be produced from 0.3mm to 2mm, and the PP sheet material is of rolling material and width of 500-1000mm.
The thickness of the plate can be produced from 2mm to 200mm. The specification is 600*1200mm 1000*1000mm 1000* 2000mm. Other specifications can be customized as needed,and The diameter of the PP rod can be produced from 2mm to 250mm, the length is 1 meter, PP rod can be ordered to be more than 3 meters in length.
Color: white and black, other colors can be customized
Modified varieties: PP sheet have various enhancers and other auxiliaries can be added to make modified varieties, depending on the requirements
Storage methods:
Keep in tight, cool and dry place to ensure good ventilation
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
