What is the absorbent material in pads？

作者：

 Oil absorbent pad is made of inert chemical polypropylene by melt blowing process. Oil absorbent mat can effectively absorb and retain liquid. The products adsorbed by oil absorbent pad are wrapped in surface treated polypropylene fiber or non-woven fabric. The outer cloth of oil sorbent pad is extremely tough and durable, with strong adsorption. The oil absorbent pad can effectively absorb the leakage liquid and prevent the diffusion of the leakage. The oil absorbent pad can be reused after extrusion, and 72% - 90% of the leakage liquid can be recovered (depending on the manufacturing process and quality of the oil sorbent pad). The advantages of oil absorbent pad are flame retardant, no dust, no storage time limit and so on. Hopetopway oil absorbent pad uses the principle of chemical adsorption. Oil absorb mat is made with lipophilic groups, so it has a certain adsorption on oily substances, which is a bit similar to exchange resin.

Here is the contene list:

● What are the characteristics of oil absorbent pad

● Difference between oil absorbent pad and felt

● Type of adsorbed pad



What are the characteristics of oil absorbent pad?

1. The oil absorber mat is formed at one time without any treatment on the surface, which is economical and opaque.

2. It has large oil absorption (10 to 20 times of self weight), fine fiber and large absorption surface area.

3. Oil absorbent pad can be suspended, which is suitable for industrial sea, river and aviation (it is more effective for treating oil slick on the water surface).

4. Fast oil absorption, suitable for ground or large-area sprinkling or laying.

5. Oil absorbent mat is necessary for dealing with all kinds of marine and river oil leakage pollution accidents.

6. Oil sorbent pad is not prone to chemical reaction (chemical resistance) and is easy to store and resistant to high temperature.

7. The oil absorber mat will not decompose and degrade, which is safe and environmentally friendly. It will not support combustion, rot or mildew (longitudinal tear resistance 43.9n, transverse tear resistance 37.5n).

8. It can be incinerated or mixed with fuel. The incineration does not produce toxic gas, and only 0.02% of the ash is incinerated at high temperature.

9. It does not contain dust and abrasive particles, which will not affect the normal operation of the equipment and damage expensive equipment.

10. Oil absorb mat is clean, light and widely used. Its adsorption capacity for vegetable oil and other water-insoluble chemicals is the same as that of petroleum solvent.

Difference between oil absorbent pad and felt.

● Oil absorbent pad has a wide range of applications. It is widely used in marine oil spill emergency treatment and various oil and chemical leakage treatment; It is very suitable for oil exploitation, petrochemical industry, shipbuilding, oil port, wharf, machinery and other industrial fields.

● Characteristics and application of oil absorbent felt. The oil absorption felt has the advantages of light weight, high oil absorption performance, uniform quality and not easy to loose, and can be reused. When there is oil slick or oil stain in the water area that needs to be cleaned, it only needs to be directly put into the water surface to absorb and recover the oil slick and oil stain. Among them, the oil absorbent felt is more suitable for light oil and benzene chemicals, while the oil absorbent felt is suitable for all kinds of oily chemicals. When a major oil spill accident occurs in the water area, an oil containment boom can be equipped to contain the spilled oil and prevent its diffusion, and then the spilled oil can be recovered by using the oil absorption felt. It is also suitable for oil pollution of various industrial and mining enterprises, oil terminals and ships; For example, the adsorption of oil-water separation filter material, the filtration and regeneration of engine oil, and the filtration of oil pollution for wastewater recycling in steel rolling plant.  

Types of adsorbed pad.

Functional classification of oil absorbent pad products: oil absorbent mat; Chemical oil absorbent pad; There are three categories of general protective oil absorbent pad;

1. Oil absorber mat is suitable for absorbing petroleum hydrogen, hydrocarbons and other non absorbent water.

2. Chemical absorbent pad series is suitable for acid, corrosive and other chemical liquids. Chemical oil sorbent pad is suitable for leakage treatment of acid, corrosive and other hazardous liquids.  

3. Universal absorb mat is suitable for oil, water, coolant, solvent, pigment, dye and other unknown liquids; The internal filler is polypropylene with surface activation treatment, so it can absorb non petroleum liquids (Universal).

 Take the  Hopetopway Chemical Spill Kit . The chemical spill kit consists of socks, gaskets, pillows and goggles, gloves, and a chemical trash can. The chemical spill kit is contained in a convenient zippered storage bag for easy transportation to and from the spill area and is compact enough to be stored in a van or behind the driver's seat if required. Chemical absorbent cotton is suitable for small areas of chemical liquid leakage, directly covering the liquid. For large area or multi-capacity leakage, adsorption cotton can be used to delineate the leakage range and gradually reduce the leakage range. According to the actual leakage area, the appropriate length of adsorption sliver should be selected, and the contact points at both ends of the sliver should be overlapped to form a strong barrier for leakage. Absorbent cotton pillow is used alone or with absorbent cotton sliver. When used, the operator can directly put the adsorption cotton pillow on a larger area (or has been s

On April 20th, 2010, the Deepwater Horizon drilling platform blew out and exploded. After burning for about 36 hours, the drilling rig finally sank in the morning of April 22. The accident resulted in the death of 11 workers and 17 injuries, and at least 560000 tons of crude oil flowed into the Gulf of Mexico, which is recognized as the largest oil spill in industrial history. In order to prevent the further expansion of the oil pollution area, the cleaning workers use physical barriers such as oil containment boom to block the oil pollution. At the same time, they drove the skimmer to clean up most of the oil slick and absorbed the residual oil slick like a sponge with an adhesive. In order to solve the problem of oil spill on the Deepwater Horizon drilling platform, workers put 5.3 million liters of oil chemicals into the oil well. Oiling agents are similar to dishwashing agents, which can effectively decompose oil and dissolve it into water, reducing the erosion of oil on the coastl

  what is a boom oil spill ? Since the 1960s, oil spills have frequently occurred. After oil spills, sea water pollution has been caused. Oil pollution will also isolate the air exchange between the atmosphere and sea water, and weaken the energy of sunlight penetrating into the sea water, resulting in serious hypoxia in the sea water, weakened photosynthesis of marine plants, unable to grow normally, and the number of marine plankton that feed on it will also decrease, thereby destroying the marine ecological balance. Not only that, after the decomposition of oil, a large number of nitrogen and phosphorus residues will be produced, leading to the eutrophication of sea water. At this time, the algae and plankton in the sea seem to get a delicious look. They greedily eat these nutrients. In the process of feeding, plankton also need a lot of oxygen, but the oxygen in sea water is very limited, so plankton and other marine organisms began to compete for oxygen, Many marine creatures suff

How are oil spills caused?

作者：
  Oil spills can have a devastating impact on the environment and wildlife, as well as on local economies that rely on tourism and fishing. These spills can be caused by a variety of factors, including accidents, natural disasters, and human activities. One common cause of oil spills is accidents involving oil tankers, pipelines, and offshore drilling platforms. These accidents can be caused by a variety of factors, including human error, equipment failure, and extreme weather conditions. For example, a tanker may run aground or collide with another vessel, resulting in the release of oil into the water. Another cause of oil spills is natural disasters, such as hurricanes, earthquakes, and tsunamis, which can damage oil infrastructure and cause spills. These disasters can also trigger landslides and mudslides, which can bury or damage pipelines, leading to spills. Human activities can also contribute to oil spills. For example, illegal dumping of oil and other hazardous substances into
