Temporary Road Mat

What is a Temporary Ground Protection Mat / Temporary Road Mat?

There are three different types of mats on the market. One is made of wood, one is made of steel, and the other is made of polyethylene. The third generation mat is by far the best option for each type. It is extremely durable, it looks great, it won't rust, it won't decay, it won't rot, and it will not puncture an ordinary tire. I got an email recently from a reader of mine that said, "I think I'm making all this up." "Paul." When I took my car in for its annual inspection, I put one of your ground mats in my trunk so I could use it as a demo. I was told by the inspection officer that he was impressed with the mat.

Why Can Hdpe High Density Polyethyleneor UHMWPE road mats For Temporary Roads be Used Instead of Steel Plates?

The paving board has a lot of strength. It is one seventh of the weight of steel plate. The surface design of the mat has raised anti-skid pattern. The anti-skid pattern of the PE polyethylene composite ground protection mat is more than 10% greater than that of the conventional asphalt or concrete ground protection mat. The ground protection mat is made of PE. The ground protection mat is easy to maintain. The mat has good chemical resistance. The ground protection mat is made of PE. The ground protection mat is made of PE.

The qualities and applications of typically utilized supporting product packaging products

Supporting product packaging products play the function of supporting and stun absorption in the item flow procedure, safeguarding the item from outside damages, so it's frequently utilized in the safety product packaging of the item.

Typically utilized supporting product packaging products
Presently, the typically utilized supporting product packaging products are primarily split into:
(1). Paper high quality: Inning accordance with the framework, it can be split into corrugated cardboard, honeycomb cardboard, pulp shaped items, and so on.;
(2). Plastic: Inning accordance with the framework, it can be split into air support, plastic movie, foam plastic, and so forth.

Paper supporting product packaging products
The advancement of paper supporting product packaging products come from in the 19th century. It was commonly utilized because of a collection of benefits such as inexpensive, extensive resources of basic materials, environmental management, simple reducing, and simple folding. Paper supporting product packaging products are all made with a specific refining technique. The product has a distinct buffer framework, and the system is deformed and takes in power to accomplish buffering and damping.

1. Corrugated cardboard
Corrugated cardboard describes the multi-layer cardboard developed by refining the corrugated base paper into a fluted form and after that glued along with package cardboard in a specific method. It comes from the corrugated sandwich board framework. Corrugated cardboard offers supporting in 2 methods the application:
①.The product itself offers a buffering impact, and the corrugated framework developed by corrugated core paper is deformed and takes in energy;
②. The product and the folded up framework offer supporting. After the corrugated cardboard is put into a specific form, the folded up setup and the corrugated setup offer supporting with each other. Corrugated cardboard has the qualities of environmental management, simple reducing, simple die-cutting, simple bonding, and inexpensive. It can be utilized in the supporting product packaging of little digital items and big house home devices.

2. Honeycomb cardboard
Honeycomb paperboard is based upon the concept of the all-natural honeycomb framework. The corrugated paper is glued and bound into numerous hollow routine hexagons to develop an entire force-receiving section just like the I-beam internet, specifically the honeycomb paper core. Both sides of the paper are bound to develop a honeycomb sandwich board framework supporting product, so the honeycomb paper core ends up being the primary framework of the honeycomb paperboard for supporting.

It has the qualities of inexpensive, light-weight, high stamina, and simple reusing. The product set you back of regular honeycomb cardboard has to do with two-thirds of hefty seven-layer corrugated cardboard with the exact same power. Compared to various other different sheet frameworks, It has one of the most considerable stamina/high quality proportion. The front side of regular honeycomb cardboard can endure 2-5Kg^cm2, which is 5 to 30 times that of routine corrugated cardboard. It's commonly utilized in digital and electric items, electromechanical items, accuracy tools, home home devices, and delicate items—cushioning product packaging. Nevertheless, when the honeycomb paperboard is affected by extreme pressure since the contortion of the honeycomb paperboard is permanent, the supporting efficiency vertical to the instructions of the honeycomb core is bad.

3. Pulp molding
Pulp mold and mildew is made from squander paper and various other grow fibers as the main raw product, including rosin periodontal, paraffin wax latex, or damp stamina representatives such as rosin, paraffin wax latex, and various other moist stamina representatives to be ruined. It's based on a steel fit together design, dried out, and designed to comply with the overview of the contents—the framework of supporting items. Pulp shaped item supporting pad takes in outside pressure power with its very own architectural contortion and even damage, thus safeguarding the item from effect or resonance in the flow procedure, so it comes from the framework contortion supporting technique.

The benefit is that it has a wide variety of resources of basic materials, such as squander papers, corrugated cardboard scraps, and so on., light-weight, practical storage space and transport, inexpensive, a specific stamina, rigidness, and supporting residential or commercial homes, and can be shaped into the exact same form as the item overview, with supporting, Placing and anti-collision in one, simple to recycle and recyclable. Nevertheless, because of the affect of drying out, power usage, and various other elements, the density of the pulp mold and mildew is restricted, so it can't be utilized for supporting product packaging of hefty products; it's not immune to several effects, has bad flexible healing efficiency, and supporting efficiency is not just comparable to foam plastics, so it's primarily utilized for electromechanical Support product packaging of items and some foods.

4. Plastic support product packaging product (Air Cushion Bag)
Plastic is a synthetic artificial product created at the starting of the 20th century. It was quickly commonly utilized in the product packaging market because of its outstanding efficiency. It's defined by different ranges, exceptional efficiency, broad application, and outstanding security.

Air Cushion Bag is a brand-new kind of birthing and supporting product framework. It's full of air in a plastic movie to develop a ruptured of consistent and constant bubbles. The forms of the bubbles are primarily columnar, semicircular, and bell-shaped. The supporting system utilizes the compressibility of the gas in the bubble to recognize the flexible work, take in the effect power, and safeguard the bundle from resonance and effect damages to accomplish the function of safeguarding the item. The supporting efficiency of the Air Cushion Bag is primarily afflicted by elements such as the density of the air support movie, the preliminary inflation stress, and the dimension of the air column.

The benefit of the Air Cushion Bag is that it's a level form throughout storage space and transport, which conserves storage space area and decreases transport expenses. The surface area of the movie is fairly smooth. Under the tons of O.O5kgf/cm^2, the sneak worth is 6 months. No greater than 30%, with outstanding supporting efficiency, it's commonly utilized in supporting product packaging for accuracy tools and some foods. Nevertheless, in the application, it ought to be kept in mind that it can't be utilized as product packaging for hefty or sharp items so regarding prevent squashing or puncturing the bubbles and ruining the product to shed its supporting impact.

LASER FOCUSING LENS

Laser Focusing Lens

What is focusing lens?

The focusing lens is the last optical device in the laser path. The anti-reflective coating on the surface of the focusing lens is made of zinc selenide (ZnSe), and the focusing lens is usually a plano-convex lens or a curved lunar surface lens. To ensure efficient laser operation, the choice of lens is critical. The type used for each machine is usually indicated in the machine manual. The laser focusing lens is used to focus the collimated light from the laser beam in various laser applications. Laser lenses include a variety of optic lens types, including PCX lenses, aspheric lenses, cylindrical lenses or laser generator lenses. Laser lenses are designed to focus light in several different ways depending on the lens type, such as focusing down to a point, a straight line or a ring. Many different types of lenses can be used in the wavelength range. 

Xi'an Huaxing Bofa shares with you about the scanning range of laser focusing lens, hope it will be helpful for you.

What is the role of laser focusing lens?

The diameter of the laser beam used by the laser cutting and engraving machine is approximately one-quarter of an inch (240 one-thousandth). In order to achieve high-quality engraving and precise cutting, the laser beam uses a mirror and focusing lens system to redirect the laser.

The laser system uses a plano-convex lens to focus the laser. The laser enters the convex lenses and starts to converge to a focal point. After passing through the focal point, the light diverges again.

How does a laser lens work?

 

The steering mirror directs the laser beam to and allows for the movement of the head and gantry transport system. Laser mirrors are designed with a high degree of reflectivity for specific wavelengths or wavelength ranges using a variety of high ware, coatings or a combination of both.

Our optical systems offer a wide range of laser lenses for a variety of laser focusing needs. Different lens types will have different spot sizes, different focal depths (focal tolerance) and different focal lengths producing different results. The focus tolerance (depth of focus) is the area with the smallest beam diameter. The larger the lens, the longer the focal tolerance. The shorter the focal length of the lens, the faster the convergence/divergence, the smaller the focal spot, and the shorter the depth of focus. So the finer the graphic, the smaller the lens should be. When we cut thicker material, it is recommended to use a larger size lens.

Some cautions you need:

 

1. The output wattage of the laser device.

2. Use and purpose (cutting or engraving).

3. The fineness of the graphic.

4. The thickness of the material to be cut or engraved. 

5. The level of resolution.

6. Regarding custom products, we can customize the size of the product, etc.

7. If it's not dirty, please don't clean it! If cleaning is required, use lens paper with solvent to clean the optical lens in a low dust and clean environment.

We offer a wide range of standard and special optic laser lenses, laser goggles, etc. Contact us to ensure the best fit for your laser cutting machine.
