1. Reassembling type prefabricated house instruction:
Lixin reassembling type prefabricated house is a kind of environmental friendly and economical type prefab house with a brand new concept. It can be organized by modulization. The frame system is made by light steel structure and the wall and roof system is made by sandwich panel. It realized the temporary construction concept as being simple and beautiful, fast installing, interchangeable and with safe and standard usage. It is a modular house product which can be industrialized produced, stored and repeated used.
2. Usage: It is widely used in field work as a temporary house such as the temporary office, meeting room, headquarters, dormitory, shop, school, hospital, parking lot, exhibition hall, maintain station, gas station at the construction site of road, railway, municipal work and so on.
3. Characteristics:
A. Stable structure: Light steel structure, safe and stable, can accord with the construction structure design standards.
B. Easy to reassemble: Can be used repeatedly. Only simple tools are needed during the installtion. 20-30m2 can be finished each day by one worker, Six workers can finished one 3K*10K standard prefab house.
C. Beautiful appearance: The whole house is bright and colorful with soft texture, smooth surface.
D. Flexible layout: The door and window can be loaded randomly and the partition wall can be put in any position of the lateral axis. The stair can be put outside.
E. Waterproof structure: The house is designed to be waterproof, no need for extra waterproof treatment.
F. Long life span: The light steel structure has be treated by the anti-rust spray paint. It can be used for 10 years at least if used properly.
G. Environmental friendly: Reasonable design, easy to reassemble, can be repeatedly used, little wastage, no building garbage. The average annual cost fot using this type of house is much lower than the one made by other material.
H. The house are made of standard components, the length and the width are both taking K(1k-1820mm) as the modulus. The horizontal size is mk+160, vertical size is nk+160.

Molybdenum was a relatively late discovered metal element, which was first extracted from molybdenite in 1792 by Swedish chemists. Molybdenum has been widely used in industry because of its high strength, high melting point, corrosion resistance, abrasion resistance and so on.
In the metallurgical industry, molybdenum is used as an additive for the production of various alloy steels, or with tungsten, nickel, cobalt, zirconium, titanium, vanadium, rhenium and other advanced alloy, in order to improve its high temperature strength, wear resistance and corrosion resistance. Molybdenum alloy steel used for the manufacture of transport equipment, locomotives, industrial machinery, and all kinds of instruments. Some 4% to 5% stainless steel containing molybdenum chemical used in the production of precision instruments and equipment for use in marine environments. With 4% ~ 9.5% high-speed steel manufacturing of high-speed cutting tools. Molybdenum and nickel chromium alloy for corrosion of metal components, aircraft parts manufacturing locomotives and cars on the. Alloys of molybdenum and tungsten, chromium, and vanadium are used to make alloy components and components for warships, tanks, guns, rockets, satellites.
Molybdenum is widely used as heating material and structural material, large electrode and gate, semiconductor and electric light source material for vacuum furnace. Because of thermal neutron capture cross section Mo small and high strength, but also can be used as structural materials in nuclear reactors.
In the chemical industry, mainly used for lubricant, molybdenum catalyst and pigment. Molybdenum disulfide has good lubrication properties at high temperature and high pressure because of its lamellar crystal structure and surface chemical properties. It is widely used as additive in oil and grease. Molybdenum is a catalyst component in the process of hydrogen desulfurization and other refining processes. It is used in the oxidation reduction reaction of ethanol, formaldehyde and oil based chemicals. Molybdenum orange is an important pigment pigment. Chemical products of molybdenum is widely used in dyes, ink, color dye, anticorrosive primer in precipitation.
