What details should be paid attention to in the process of making Rapid prototye

An important role of Rapid Prototypes is to check whether the design of the drawing is reasonable. If the product designed by a product has not been improved in structure, function and other aspects

To verify a large number of production defects, and then put into production. This will cause huge economic losses.
So what details do we need to pay attention to in the production process of hand board proofing?

1. When bonding ABS products, pay attention to the amount of glue more or less, do not have cracking phenomenon.

2. The production process and drawings should be carefully read

3. Manual grinding should grasp the dimension accuracy of the hand board.

4. When the acrylic hand board is bonded, there should be no cracks or bubbles.

5. Don't glue the wrong place, and don't have dislocation and gap during assembly.

6. The temperature of PC products should not be too high when it is put in the oven or blown by air duct

7. POM, nylon, aluminum alloy products can not be bonded, because the glue of these three materials is not stable, so try not to use CNC disassembly processing.

8. If the workpiece has R angle, don't make it into a right angle. If there is arc on the edge of the workpiece, you should also pay attention to it

9. In the aspect of fuel injection, there should be no color difference, paint dropping and other phenomena, and the dust point should be controlled during oil mixing and fuel injection.

10. Pay attention not to deform and shrink, not to have too many bubbles, and consider shrinkage.

 

Precautions during the decoration of container houses.

The container houses realizes the energy-saving effect of the building through scientific and reasonable layout, such as the design of the building's own space form, envelope structure, building materials and structure.

The building energy-saving technology of container houses specifically refers to the realization of building needs through reasonable layout of building orientation, setting of shading, thermal insulation technology of building envelope, and design of building openings that are conducive to natural ventilation in building planning and design. Energy consumption of heating, air-conditioning, and ventilation is reduced.

Container houses addition technology: building shape factor is suitable for energy saving, orientation suitable for ventilation, sun room design, pebble wall energy storage, fixed shading, solar wind shaft, natural lighting, etc., through the shape and structure design of the building itself, energy saving and environmental protection are realized To achieve green effects, these are all additive technologies.

This is the reason why container houses are widely praised by people, and the most important point among them is the low price. The price of the container house itself is not high, so there is no need to make the interior decoration very luxurious. Customers can decorate according to actual needs. However, if you find a problem that is difficult to solve during the decoration process, you must contact the manufacturer in time.



Precautions during the decoration of container houses:

In order to ensure the decoration quality of the container houses, the selection of materials must meet the requirements, and the structural stability must be guaranteed. For example, the ceiling of the container house must be a fixed structure. When installing lamps and other lighting equipment, pay attention to whether the specifications are appropriate and cannot be damaged. The tightness of the structure of the house itself. Secondly, the outer surface and frame of the sandwich panel are made of steel. The interior insulation must be considered when decorating, so as not to cause undesirable conditions such as leakage of electricity to appear in the house.

Users must pay attention to the common problems in the above decoration, so as not to encounter various problems during the use process, which requires re-installation. After the container house is installed, the user must not change the structure of the house without authorization, nor disassemble any accessories at will, and cannot add or reduce the partition wall without authorization. If you must make changes, you can first consult a professional before making modifications. In addition, users should also do a good job in the maintenance and maintenance of container houses, and it is best to refresh them with paint every two years.

Before building a container houses, we must not only listen to professional and reasonable opinions, but also design the construction of the house. After doing the basic work carefully, we must pay attention to the details of each installation, such as The firmness of welding and so on. As long as the sturdiness and safety of the container house is ensured, the container houses can be used with confidence, and the living will be more comfortable.

 

 

 

 

 

What to pay attention to when buying barreled peanut oil

Many consumers like to buy large-capacity barrels of peanut oil, thinking that it can save worry and is cheaper than the price of oil in small packages, but the editor reminds everyone to pay attention to an important problem: that is, peanut oil should not be stored for a long time, and it is easy to deteriorate. Because of grease Oxidation will occur automatically, and the oxidation of fats will produce many toxic oxidizing substances.If people eat oxidized fats for a long time, they will cause cell function failure and induce various diseases.

1. Try to buy products with brand awareness and high market share. When purchasing, pay attention to whether there is QS logo, peanut oil company name, peanut oil factory address, grade, production date, shelf life, etc. on the product label.

2. The purchase of barreled peanut oil firstly depends on whether there are oil traces on the barrel mouth. If there is, it means that the seal is not tight, which will cause the oil to be oxidized during storage. Secondly, it depends on whether there is precipitation at the bottom of the barrel and the oil with low processing accuracy. After being placed for a period of time, different degrees of precipitation will inevitably occur.

3. Look at the production date and shelf life. If the shelf life is more than one year, antioxidants are generally added. In addition, it is best not to buy oil that has a shelf life of one or two months. Because the oil that has been irradiated by the sun for a long time, the actual quality is It has dropped a lot during the warranty period.

4. For families with a small population and few fires, it is best to buy small-volume barrels of peanut oil.

1. When buying oil, choose the one with a relatively recent production date, and the closer it is, the more fresh it is.

2. Buy a small package of oil, convert it according to the amount of 25-30 grams per person per day, and use the amount that can be used in one and a half months. For example, if two elderly people are at home, try to buy a package of less than 1.8 liters, if you often eat at home For a family of three, you can buy 2.5 liters of peanut oil.

3.If you bought a large barrel of oil for convenience or cost-effectiveness, you can pour a part of it into the oil control pot, and then seal the large barrel with tape and place it in a cool, dry and dark place, so it is best to use it within 3 months.

4. If you choose to divide into small bottles and then eat, divide into clean vials, pay attention to the bottles should be dry, can not carry water, brown glass bottles are preferred.

The shower room must be fixed. The fixing method is generally to use screws to leave the holes on the aluminum alloy frame on the wall. All that needs to be done is to mark the corresponding position on the wall. The method is to put the frame on the wall, make sure the position is correct with a tape measure, and then mark the wall with a pencil.

2: Punch holes, use percussion drills

After setting the position, the next step is to punch. Punching is also divided into two steps. First, use a circular percussion drill to make a shallower hole at the marked location on the wall; construction tips: the bathroom wall has been covered with bricks, which is relatively hard. In order to make drilling easier, you can wet the drill bit. In addition, you can pour some water while drilling; after drilling the prototype mark hole, the next step is to use a spiral with stronger impact. The drill is out. On the basis of the shallower holes that have been punched, make a deeper hole.

Three: Install rubber pellets, use a hand hammer

Before screwing the screws into the wall, you need to install the expansion rubber particles in the holes first. The rubber particles can better tighten the screws. Use a hand hammer to knock the rubber particles into the drilled hole.

4: Fix the frame, use an electric screwdriver

After the above steps are completed, you can install the shower room frame, put the bottom frame on the water retaining strip, and then fix the frame. The method is to use an electric screwdriver to drive the screws into the wall to fix the frame.
