Genuine leather handbags get dirty after a long time,don't throw them away!

2020-04-03 19:01:48 | 高齢社会
Bags have been used for a long time. In addition to wear and tear, stains will always fall on the bags, which is very difficult to clean, or even not clean at all, and can only be lost, but it is really a waste!

White bag is yellow, don't know how to clean it?
You can use face creams and hand creams to remove yellow hand creams and face creams at home. Do not discard them. Cleaning leather products often has unexpected results. Be sure to wipe it a few times to see the effect. If you have milk and petroleum jelly in your home, you can coat the freshly treated yellow part as a daily maintenance method to prevent the appearance of yellow.

There are oil stains on the bag. It is always inevitable that the leather bag is stained with oil stains. You can directly use detergent, but you must brush it gently to avoid damage to the leather. If it is a white leather bag, you can mix 1:10 with bleach and water and then wash it.

If there are traces of strokes on the bag, you can squeeze a little shower milk in warm water, and then wet the cloth to wipe the traces of the strokes on the bag, and then wipe the water off the bag with a dry paper towel. If you get it with a ballpoint pen, use some toothpaste and a small amount of soap to gently rub, then wipe with alcohol.

There is also a very common problem, that is, the bottom of the handbag is prone to wear scars. If it is not handled in time, it will wear out and become worse, and even the most expensive bags will not look textured. In fact, as long as you apply the adhesive on the edge of the strap evenly, do not apply it too thick, apply a layer first and wait for it to dry, then apply a layer, so apply a total of about five layers, after drying, it will be the same as the new one La.

How to clean up stained stains. Wear light-colored leather bags with jeans and wear them over time. The clean leather bags will be stained with light blue! Dip a cleansing milk on a cotton pad and wipe back and forth a few times to remove the denim stains on the bag. I chose makeup remover because it doesn't have irritating chemicals, so it won't hurt your purse.

So how to maintain the bag?
Before each storage of leather products, they should be dusted and cleaned, and then the leather maintenance oil should be applied. Apply oil to a clean cotton cloth before wiping the surface evenly. Leather bags can be wiped with a high-density nano-sponge. If it is slightly dirty, you can use a white eraser of a normal pencil to quietly remove it. Severe soiling can be wiped with a high-density nano-sponge with a wipe of water. Before cleaning, wipe it on an inconspicuous area to see if it fades, and then use genuine leather handbags care agent to clean and maintain it, which can prolong its life.

Reinforcement Geosynthetics (Geogrid Mat) Application

2020-04-03 19:01:19 | 高齢社会
For the ancients with low technological level and underdeveloped productivity, it was needed to rely on completely natural materials and manual labor to solve corresponding engineering problems such as transportation on soft foundations and dams. This article analyzes and elaborates the correspondence between the antient mechanism and modern geosynthetics from the following aspects.

Soft foundation traffic and reinforced cushion
When transporting on weak soft roads and foundations, problems such as loading capacity, deformation and subsidence are need to be resolved.

1. Records of ancient books
In the "Three Kingdoms" written by Chen Shou, Cao Cao was defeated and went through Huarong Road: "The muddy road was inaccessible ... Then he ordered the soldiers to cover the road with grass then they could finally pass the road."

2. Modern development
Before landing in Normandy, in order to ensure that vehicle and personnel moved freely on the soft sandy beach, the Allies developed an AVRE paving vehicle based on the Churchill tank chassis, which was laid on the basis of thick linen and was reinforced with small branches. (this cushion can be looked as "geotextile").

3. Mechanism analysis
The main mechanism of the above methods can be explained like the formation of a backing plate acting on a weak or loose foundation which could well bear the transport by expanding the stress area, increasing the strength of foundation surface to avoid deformation. Its mechanism is similar to the reinforced cushion which is currently widely used in the engineering filed.
The geosynthetics reinforced cushion is composed of a combination of soil cushion and geosynthetics such as a geogrid mat, geocell, etc., which are layered in the cushion. Compared with common cushions, the tensile and shear properties of reinforced cushions are significantly improved, which effectively prevents the cushions from breaking and shearing damage, and ensures the integrity of the cushions. Meanwhile, the rigidity of the reinforced cushion layer is large, which performs the limitation and homogenization of the soft soil deformation and reduces the amount of settlement.

Hydraulic protection
In order to ensure the safety of channels, especially to reduce the hazards such as flood erosion, it is necessary to strengthen and protect its embankment. This article briefly compares the applications of ancient technology and modern geosynthetics in this regard.

1. Ancient technology
Fascine works is a hydraulic component used in projects such as bank protection, plugging and embankment. It was widely used in the Song Dynasty, and the fascine works coiling technology had become considerably mature. Fascine works has the characteristics of taking materials onsite and fast making. It can not only resist the erosion of the river bank and dam stacks during the flood period, prevent the bank from collapsing, but also is suitable for river closure, water invasion and dam construction, plugging and breaching. It was widely used in river management and flood emergency.

2. Modern technology
Geosynthetics such as geobags, geotubes, soft body mattress, geogrid mats, geocells, grids, geonets, etc. can be used in water conservancy engineering facilities such as protection, reinforcement, flood protection and emergency rescue. Their function principle is to play the role of reinforcement, protection, and separation of geosynthetics. For example, only one phase of the Yangtze River Estuary Regulation project used geosynthetics such as soft body mattress for more than 10 million m2.

Reinforced soil technology
Placing geogrid mat and geotextile in the soil to form a force stressing system can improve the overall strength and deformation properties, that is, it reflects the "reinforcement" function of geosynthetics by strengthening the soil. This principle is utilized in natural and traditional architecture, and also has been widely utilized in modern engineering.

1. Reinforced soil structure in nature
The Tang Dynasty poet Bai Juyi wrote: "Several early warbler contends for warming tree, whose fresh swallow pecks spring mud." The swallow nest itself is an embodiment of the technology of reinforced soil. The branches and leaves form the framework of the bird's nest, which are well bonded with the soil to form an integrity. Otherwise, the stiffness and integrity of pure soil or pure branches and leaves will be significantly reduced.

2.Application of natural materials reinforcement in traditional engineering
In the Liangzhu culture water conservancy site, the "grass-wrapped mud" technology was used to fill dams and other facilities; the Great Wall in the Han Dynasty was built with the utilization of red willow reeds as reinforced materials. The technology of applying natural materials to reinforce soil structures has been passed down to current day and is continuously used in some fields.

3. Modern reinforced soil technology
Reinforced soil retaining walls utilize geogrid mat as reinforced material and wrapped panel. The research and application of reinforced soil technology is becoming more and more extensive, and has broad development prospects.

It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, pipes, packaging films and so on.

PVC floor protection film is everywhere around us. In the process of decorating our home, walls, floors, furniture, etc. will inevitably be adhered to the gray layer, cement, and even scratched by paint or other hard objects. Some of the tiles cost nearly 10,000 yuan, and they were messed up before they were finished. Adding a layer of decorative floor protection film to the ground during decoration can prevent the above.

PVC can be used as a single layer of pvc plastic sheet, or a layer of knitted cotton can be added on the reverse side of PVC. Features: non-slip, wear-resistant, cushioning, shock absorption. PVC protective film can be used for floors, windows and doors, tiles, furniture, etc. PVC floor protection film is generally colored when it is made, red background, yellow background, white background, green background, orange background, etc., and it can print and print, and the advertising effect is excellent. The ground protection film printed with the company's LOGO is used for advertising on the construction site, which can improve the overall image of the construction site.

Decoration floor protection film has a floor protection film made of PVC + needle cotton. This type of protection film can improve the buffering performance of the protection film. Wall protection film made of PVC + pearl cotton, high quality and low price. The transparent protective film has a long service life and can be recycled 4-5 times.
