Most of the requirements  for the use of long-term to maintain the original appearance of the building  is. In determining the selection of stainless steel type, the main  consideration is the required standards of beauty, location of the atmospheric  corrosion as well as to the use of the cleaning system.

  However, other  application more and more is only seeking the structural integrity or  impermeable. For example, the industrial construction of roof and side wall. In  these applications, the owner of the building cost may be more important than  aesthetic, not very clean surface can also be.

  In a dry indoor  environment using430stainless steel, the effect is quite good. However, in the  country and the city to maintain its appearance on outdoor, often need  cleaning. In seriously polluted industrial area and coastal areas, surface will  be very dirty, even causing rust. But to obtain the outdoor environment  aesthetic effect, it required the use of nickel containing stainless steel.  So,304 stainless steel is widely used in curtain wall, side walls, roof and  other construction purposes, but in the erosion of the serious industrial or  marine atmosphere, preferably made of 316 stainless steel.

  Now, people have fully  realized in the structural use of seamless stainless steel superiority. There  are several design criteria included304 and316 stainless steel. Because"  bipolar" stainless steel 2205has good corrosion resistance and high  tensile strength and elastic strength com., therefore, the European guidelines  are also included in the steel.

  Stainless steel product  shape

  In fact, stainless steel  with a standard metal shapes and dimensions production, and there are many  special shape. The most commonly used products are made of sheet and strip, and  plate used in the production of special products, for example, the production  of Hot-Rolled Structural Steel and extrusion structure steel. But there are  circular, elliptical, square, rectangular and six corner welded pipe and  seamless steel pipe and other products, including profiles, bar, wire rod and  castings.

  Surface state

  As would later on, in  order to meet the aesthetic requirements of architects, has developed a variety  of different commercially available surface processing. For example, the  surface can be highly reflective or glossy; can be smooth, polished or  embossed; can be colored, color, plating or etching pattern on surface of  stainless steel, in order to meet the design requirements for the appearance of  various.

  Keep the surface state  is easy. Only occasionally washing can remove dust. Because of good corrosion  resistance, can be easily removed from the surface of graffiti pollution or  other similar surface contamination.

  Editor this paragraph  stainless steel design

  More than 60years,  architects have been made of stainless steel to build cost-effective permanent  building. Many of the existing buildings illustrates that this choice is  correct. Some are very ornamental, such as New York Chrysler mansion. But in  many other applications, stainless steel the role is not so attract sb.'s  attention, but in the building of the aesthetics and performance is plays an  important role in. For example, because the stainless steel than other same  thickness of metal material having abrasion resistance and resistance to indentation,  so in a large population flows of local building sidewalks, it is the design of  choice materials.

  Stainless steel used in  the construction of new buildings and used to repair the historical places of  historic interest and scenic beauty of structure materials for more than 70  years. Early in the design is in accordance with the basic principles of  calculation. Today, design specifications, for example, American Society of  civil engineers of the standard ANSI/ASCE-8-90" cold formed stainless steel  structure design code" and NiDI and Euro Inox published jointly by  the" structure of stainless steel design manual" has been simplified  by the use of long service life, good integrity of the building structure  design.

  Editor this paragraph  stainless steel future prospect

  Because the stainless  steel has the building materials requested by many desirable properties, it can  be said to be the one and only in the metal, and its development continued. In  order to make the traditional application of stainless steel in neutral better,  has been in the improvement of existing types, but, in order to meet the strict  requirements of advanced building application, now the development of new  Stainless steel seamless tube. Due to constantly improve production efficiency,  continuous quality improvement, stainless steel has become the architects to  select the most cost-effective material for one.

The lawn mower  maintenance

  After using lawn mower protection first,  put it all clean: next, check that all the screws, oil, oil surface, empty  filter, blades for defect, again, according to the lawn mower use fixed number  of year, strengthen the vulnerability of the inspection or replacement parts.  Periodic maintenance is more important.

  (1) the oil maintenance

  Each time you use lawn mower will check the oil  before oil noodles, see if in oil among ruler. The head should be 5 hours a  change of oil, 10 hours after should be a change of oil, according to situation  frequently after an oil change. Changing the oil in the engine should be in the  heat engine state, like this can the old oil completely replaced. If the oil  excessive will appear: launch difficulties, or black smoke particularly big, or  power small (coke formation, the spark plug gap cylinder too small), or engine  too much heat. If the oil too little will appear: engine gear noise or damage,  or $plug rim wear big, damage, or appear to pull tile phenomenon, cause  seriously damage the engine. So the oil maintenance is very important.

  2) the lawn mower air filter device  maintenance

  Every time before and after using use check  whether dirty, should frequently change frequently wash: if too dirty can lead  to engine difficult launched, black  stretching  small.

  (3) lawn mower and oil routes  carburetor maintenance

  Every time that should have added petrol  filter filtering, and it can't be long time put in the fuel tank inside, clean  carburetors used special carburetor cleaning, cleaning cycle depending on the  degree of carburetor dirty will decide. If gasoline engines fail, the engine won't start or  start immediately after flameout, should be cleaned.

The three major categories of blow molding  machine

    Blow molding machine can  be divided into extrusion blow molding machine, injection blow molding machine and  special structure blow molding machine three categories. Stretching blow  molding machine may be relegated to the above in each category. Extrusion blow molding machine is extruder and blow  molding machine niv mode combination of institutions, the extruder and type of  billet die head, huff device, molmerged institutions, type slab thickness  control system and transmission mechanism composition. Type the die head is  decided to blow molding billet products one of important component of quality,  there are usually side feeding type die and the central feeding mould head.  Large products used more storage when blow material cylinder type billet die  head. Storage materials for 1 kg  minimum volume cylinder, the maximum of up to 240 kg. Type slab thickness control device used to  control type slab wall thickness, the control points as many as 128 points,  generally for 20 ~ 30 points. Extrusion blow molding machine production volume  can be a range of 2.5 ml to 104 l  hollow products.

    Injection blow molding  machine is the combination of injection molding machine and blow molding  institutions, including plasticizing institutions, hydraulic system, control  electric appliance and other mechanical components. Common types have three  station injection blow molding machine and 4 Labour injection blow molding  machine. 3 Labour machines are preform, prefabricated type huff and stripping  three points, each workstation are 120 °. 4 Labour machine is a progressive  advance molding, each workstation are 90 °. In addition, there are between 180  ° of progressive apart double location injection blow molding machine.  Injection blow molding machine production of plastic container size is exact,  without a second process, but the higher cost of mould.

    Special structure blow  molding machine is to use sheet material and molten material and the cold  billet for blow molding with special shape of billet and use of hollow blow  molding machine body. Because the production of products of shape and different  requirements for blow molding machine structure also each different.
