Comparison of EPE pearl cotton, EVA, sponge and EPS Foam

Comparison of advantages and disadvantages of EPE pearl cotton, EVA, sponge and EPS
(1) Pearl cotton
EPE (expandable polyethylene) is expandable polyethylene, also known as pearl cotton. The cross linked closed hole structure is made of low density polyethylene (LDPE) as the main material. It is made of low density polyethylene (PE) with numerous independent bubbles formed by physical foaming.
Strengths
1. EPE pearl cotton overcomes the defects of fragile, deformation and poor recovery of general styrofoam. It has many advantages, such as water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong tolerance, recycling, environmental protection, strong collision resistance and so on. It also has excellent chemical resistance.
2. There is no waste gas and waste water in the production process of EPE pearl cotton. The auxiliary material for producing pearl cotton is physical foaming without chemical reaction.
3. The waste EPE pearl cotton can be recycled and decomposed naturally, which is environmentally friendly and pollution-free.
(2) EVA
EVA rubber and plastic products are new environmental protection plastic foaming materials, which are widely used in the packaging materials of mobile phones, computers, cosmetics, gifts, toys, speaker linings, TVs and lighting, lithium-ion batteries, automatic recorders and other products.
Strengths
1. EVA has outstanding advantages such as cushioning, earthquake resistance, heat insulation, moisture resistance and chemical corrosion resistance, and is non-toxic and non absorbent;
2. EVA has outstanding flexibility and elasticity. It can absorb and disperse external impact force through bending and achieve a series of excellent application characteristics such as cushioning.
defect
EVA is solid and a little heavy when it is too thick.
(3) Sponges
Sponges are mostly composed of polyisocyanates and polyols. The base reaction is the reaction between polyols and polyisocyanates to produce polyurethane. The commonly used spongy science is called polyurethane soft foaming rubber. Polyurethane is a common polymer material in the days.
Strengths
Sponge has outstanding properties of heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, air permeability and so on.

Disadvantages
Sponge waste needs to be naturally absorbed for a long time. If the method of incineration is adopted to treat sponge waste, toxic gases such as carbon monoxide, hydrogen cyanide and formaldehyde will occur and pollute the environment.
(four) EPS (polystyrene foam)
Polystyrene foam (ExpandedPolystyrene referred to as EPS) is a light polymer. It uses polystyrene resin to take part in foaming agent, heating and softening, forming gas and forming a rigid closed cell structure.

Pentane is the most common expansion agent in EPS production. Low concentration of pentane can be trapped during production, inside the closed cells of EPS.

Strengths:
1. It has the characteristics of cushioning, insulation, heat insulation, sound insulation and anti vibration. Because of its extremely low thermal conductivity, it is widely used in thermal insulation materials.
2. the EPS plastic foam is moulds and moulds, and is suitable for mass production. The production efficiency is high and the cost is low.
Shortcomings:
1. EPS is brittle and easy to break, with poor bending resistance;
2. EPS is a simple form of granular foam in packaging.
3. EPS is not environmentally friendly.

What is the chemical resistance of expanded polystyrene?
Its physical properties do not change within its service temperature range (i.e. up to 167°F/75°C) for long term temperature exposure. Its chemical resistance is nearly equivalent to the material upon which it is based – polystyrene. EPS is 98% air and it is recyclable.

What is expanded polystyrene (EPS) foam?
What is Expanded Polystyrene (EPS) foam? The word Styrofoam™ is often used to describe expanded polystyrene (EPS) foam; however, ‘Styrofoam’ is actually a trademarked term for closed-cell extruded polystyrene foam made for thermal insulation and craft applications. EPS foam is the correct term for any form of expanded polystyrene. Expanded polystyrene (EPS) is produced from a mixture of about 90-95% polystyrene and 5-10% gaseous blowing agent, most commonly pentane.
The initial blowing agent employed is pentane which is the VOC that requires abatement. Typically, a blowing agent content of EPS beads is 3.5 to 6.5% of Pentane by weight.
EPS operation typically requires customized emission control systems to handle the high VOC concentrations that emanate from raw material, container opening, pre-expansion, aging, molding and storage processes of production.

Standards.

(1) The pentane must be composed solely of carbon, hydrogen, oxygen, nitrogen, and sulfur.

(2) The pentane must meet the standards for blender-commercial grade pentane or blender-non-commercial grade pentane.

Optimization Process of Sodium Methylate

The Production Process Optimization of Sodium Methylate with Sodium Hydroxide and Methanol

The current preparations of sodium methylate are mainly two methods of sodium and sodium hydroxides.

At present, there are mainly two production methods: metal sodium method and alkali method. Sodium metal method refers to solid bulk or molten metal sodium reacts directly with lower alcohols to produce sodium alcohol and hydrogen

The advantages of sodium methoxide are high purity, simple process, low equipment cost and unsafe, the generated hydrogen is very easy to explode, and the raw metal sodium is very active and expensive.

Sodium Methoxide 30% Solution in Methanol, CAS No.124-41-4

Alkali Method

It refers to the reaction of methanol and sodium hydroxide to produce sodium methoxide and water. The advantage of this method is that the raw material is convenient

The utility model has the advantages of easy availability, low cost and safe operation. Its reaction is reversible, but it is very easy to cause reverse reaction

It should not be complete. There are often impurities such as sodium hydroxide in the product, so it is not necessary for alkali production

Remove the water and add catalyst to make the reaction move towards the product as far as possible.

Distillation and other separation operations shall be carried out to reduce impurities as much as possible.

Sodium process is simple, high conversion rate, but too dangerous. Alkaline process is low conversion rate because of its strong reversibility while needed to continuously remove the water of reaction, but it is low cost. The actual production is produced by reactive distillation apparatus. The major influence factors of the reaction are reaction temperature, mass ratio of methanol and sodium hydroxide, and reaction time. Using single -factor experiment method, the law of reaction with the changes of the influence factors was studied. Experimental results showed that the higher the mass fraction of sodium methylate was obtained, the higher temperature increases, the greater the mass ratio of methanol and sodium hydroxide , the longer the reaction time. The optimal reaction conditions were determined.

2022 the Strongest Methanol Manufacturers in China

On February 21, China Nitrogen Fertilizer Industry Association held the 2022 China methanol industry conference in Hangzhou to summarize the work of methanol industry in 2021 and analyze and discuss the methanol market and development trend in 2022. On the same day, China nitrogen fertilizer industry association commended the top 20 national methanol production enterprises in 2021 and advanced energy-saving enterprises in the methanol industry.
Gu zongqin, President of China nitrogenous fertilizer industry association, pointed out at the meeting that at present, the development of methanol is facing positive factors such as the recovery of the world economy, the steady rise of international oil prices, the continuous increase of downstream product consumption and the easing of overcapacity. However, we should also see the adverse factors and still face many challenges.
Gu zongqin believes that with the economic recovery of various countries, the demand for chemical products will inevitably increase, which will further drive the recovery of methanol prices. At the same time, the recovery of international oil prices will drive the rise of foreign methanol prices, help to improve the competitiveness of domestic coal based methanol production, and will also strongly support domestic prices.

The consumption data in recent ten years show that the growth of methanol consumption in China is roughly more than 10% every year. Gu zongqin predicted that the growth of methanol consumption in the next few years will also maintain the previous trend for three reasons: first, the pilot work of methanol vehicles will continue; Secondly, alcohol based fuels for boilers and stoves as clean substitutes for coal can greatly improve air quality; Third, the consumption of methanol downstream products will continue to grow, and coal to olefin is still the main direction of the development of the industry. In addition, new downstream products are still being researched and developed, such as toluene methanol methylation to produce p-xylene.
However, China’s methanol industry still faces a series of challenges. Gu zongqin said that the task of removing production capacity this year is still arduous, the development of upstream and downstream is still unbalanced, the pressure on safety and environmental protection continues to escalate, and the price of raw materials is facing rising pressure.
Although the methanol units that have stopped production for two consecutive years are more than 9 million tons / year, involving more than 120 production enterprises. However, Gu zongqin pointed out that with the improvement of the market, some old production capacity with high energy consumption, high emission and backward devices may be driven. In addition, a large number of new units are still put into operation and technological transformation and capacity expansion every year, resulting in a high rate of increase in methanol production capacity, and the task of eliminating backward production capacity is very arduous.
The pressure of safety and environmental protection in methanol industry will continue to escalate. Gu zongqin said that as a chemical enterprise with high energy consumption and high emission, methanol enterprises are facing great pressure from many aspects, such as the significant rise of environmental protection treatment costs and power costs, as well as the shutdown and production restriction according to the emission reduction requirements during the emergency response period.
In order to realize the high-quality development of methanol industry, Gu zongqin proposed to do a good job in five aspects this year: continue to do a good job in reducing production capacity; Accelerate the adjustment of product structure, expand the industrial chain, and improve product added value and market competitiveness; Accelerate the popularization and application of advanced technology and promote the technological progress of the industry; Further improve the level of energy conservation and emission reduction in the industry; Actively carry out international exchanges and cooperation.
Junyuan Petroleum Group has made remarkable achievements in tapping energy-saving potential, deepening energy conservation and emission reduction and improving energy utilization, Won the title of “advanced enterprise in energy conservation in methanol industry in 2021”.
