On January 22, 2006, the company's self-developed SWE series of multi-functional small hydraulic excavators and SWDM series rotary drilling rigs passed the new product appraisal in Shanhe Intelligent Industrial Park.
With the advancement of society and the increase of various infrastructure maintenance projects, small construction machinery represented by small excavators with multi-functional operation characteristics is widely used in small earth and stone works, municipal construction, road repair, concrete crushing, and buried cables. , the laying of water pipes, garden cultivation and river dredging. The SWE series multi-functional small hydraulic excavator independently developed by our company contains 7 national patent technologies and has been widely recognized by the market and is being exported to the European market in batches. The expansion of this series of products can increase market share, replace imports, achieve exports, earn foreign exchange, establish brands, and win glory for the nation.
The need for engineering construction has promoted the rapid development of new pile driving machinery. The multi-functional rotary drilling rig with high technical level, rapid construction and wide application range represented by cast-in-place pile has strong vitality. Shanhe Intelligent SWDM series rotary drilling rig has independent intellectual property rights. It has two national patent technologies and one computer software copyright. It is the most advanced rotary drilling rig in China. The product has several technical advantages such as integrated control system, intelligent ergonomics technology, environmental protection and energy saving, high reliability, high construction quality and wide application range. The structural parts are firm and reliable, and have strong impact resistance; the power head can provide super-large torque; supporting short-screw drill bits, ordinary drills, sand-drilling drills and Other drilling tools to achieve functional operation, which can adapt to clay layer, sand layer, pebble layer, etc. A variety of formations.
It is the best choice for the construction of large diameter pile foundation engineering. In terms of realizing foreign exchange earning, resisting imports, and revitalizing national industries, it has great progressive significance, and with the opening of the international market, there is also an opportunity for export.
This new product appraisal will be organized by the Hunan Provincial Machinery Industry Management Office, the Provincial Economic Commission, the Municipal Economic Commission, the Provincial Science and Technology Department, the Provincial Quality and Technical Supervision Bureau, the Provincial New Technology Promotion Station and other relevant authorities, and invited research institutes from all over the country. Well-known experts in the industry of enterprises and associations, representatives of national construction urban construction machinery quality supervision and inspection centers and customer representatives form an appraisal committee.
The experts of the appraisal committee listened to the product technical report, product inspection report, user usage report, reviewed the relevant technical documents, and inspected and tested the product on site. After thorough discussion, they finally agreed that the two series of products are reasonable in design and superior in performance. It has complete functions, high reliability, high efficiency and energy saving, and has reached the advanced technology level of international similar products.
Phenolic Rosin Ester (Rosin Modified Phenolic Resin) is made in irregular transparent lump through polycondensation and esterification by Gum Rosin, different phenols, aldehydes,and polyhydric alcohol.
It is soluble in ester, vegetable oil, turpentine,and insoluble in alcohol and water.
This material is used mainly for offset printing for products such as newspapers and magazines. This is a special resin made by modifying a Synthetic Resin, phenol, with a natural resin, rosin. The performance of the resin is determined mainly by the modifier, rosin.
