The problems existing in the recycling of steel drum 2021-07-01

The reuse of old steel drums is also the product of environmental economic development in recent years.With the increase of national environmental protection policy and hazardous waste disposal, the upstream production and use enterprises have a new understanding of the management and disposal of their packaging materials.Many chemical companies recycle barrels of their own products for reuse or for peer-to-peer services.

Why is it easy to crack around the welding seam? Let you know what the welding heat affected zone is. 2021-06-17

Weld heat affected zone (HAZ) is different from welds in that welds can be adjusted by chemical composition, redistribution and proper welding process to ensure the performance requirements, while HAZ performance cannot be adjusted by chemical composition. It is the problem of uneven distribution of tissue that occurs under the action of thermal cycling.For the general welding structure, the main consideration of the heat affected zone hardening, embrittlement, toughening, softening, and comprehensive mechanical properties, corrosion resistance and fatigue performance, which should be determined according to the specific use requirements of the welding structure.

A brief analysis of the "particle" problem of waterborne coatings 2021-06-16

Water-based coating engineer should have such experiments, the pull rod, when we to prepare waterborne industrial coatings anchor rods in the process, if the coating system is very fit, coating internal entropy stable ", so out of bars is a nice layer of liquid film, we usually choose wire rods out of film thickness is 100 microns.If the water-based coating is not perfect, or it is a little defective, it is easy to pull the rod, there are some particles.

Solution of blistering prickly heat in the process of waterborne coating 2021-05-31

The problems of prickly heat, running hang and blistering caused by running hang in the coating production line of waterborne coatings were introduced. The causes of the defects were analyzed from the aspects of coating environment, equipment, materials and management, and the countermeasures were formulated. Through continuous improvement, the problems of prickly heat and blistering were solved.

How about the overall situation of China's packaging industry?A penny to understand! 2021-05-26

According to the data of China Packaging Federation, the total output value of the packaging industry in 2019 is 2.22 trillion, with a year-on-year growth of 1.5%;The output value of plastic packaging was the highest, accounting for 43.0%, the output value of paper packaging was 29.0%, the output value of metal packaging was 11.7%, and the output value of glass packaging was the least, accounting for 6.1%.

North American Packaging Market and Development Trends in 2021 2021-05-18

From 2012 to 2016, the market size of the global packaging industry increased from US $741.2 billion to US $869.3 billion, with an average annual growth rate of 4.3%.Paper packaging share to 2016 corresponding to the total packaging scale of nearly 36%.In 2018, flexible packaging enterprises in North America were very active. According to incomplete statistics, the total sales of the top 10 flexible packaging enterprises accounted for 55% of the total sales of the flexible packaging market in North America.

I'd like to tell you about additives in waterborne coatings 2021-05-10

In recent years, the country constantly calls for energy conservation, environmental protection policies, to various industries put forward higher requirements.Water-in-water coating has a good prospect for development because of its good environmental performance.As one of the essential raw materials for the production of coatings, the use of auxiliaries continues to increase with the wide use of waterborne coatings.In addition, the properties of additives also directly affect the environmental performance of waterborne coatings.That is to say, the quality of additives to a certain extent determines the quality of water-based coating products.Therefore, it is beneficial to strengthen the research on the auxiliaries for waterborne coatings to improve their quality and effect.

Five principles of transport packaging design, all related to steel drums, especially non-standard steel drums should be paid attention to 2021-04-28

China has formulated relatively complete national standards for the size series, quality, marking, environmental conditions and basic tests of logistics and transportation packages, and priority should be given to national standards in the design of logistics and transportation packages.Exporting products should also consider adopting ISO or relevant standards of the exporting country.For example, ISO has taken 600mmX400mm as the base number of the length and width of the package, which becomes the packaging module. The design of logistics and transportation packaging should be based on this as much as possible.The standardization of logistics transportation packaging is beneficial to the recovery and reuse of collective packaging containers.If standardized pallets could be shared globally, pallet costs could be reduced by more than a third.

Knowledge window | water-based paint coating wastewater treatment method 2021-04-26

As the national environmental protection requirements are becoming more and more strict, the country is also paying more and more attention to the treatment of environmental pollution, the market share of water-based coatings in the coating industry is also increasing year by year.Waterborne coatings have been applied in many products such as containers, automobiles and parts, construction machinery, furniture, etc., and the discharge of coating wastewater is also gradually increasing. The treatment of the corresponding water-borne coatings coating wastewater has become a headache problem for many enterprises.

[Market Frontier] the chemical packaging supply chain under the "violent rise" of raw material prices 2021-04-21

The beginning of 2021 is not easy, raw materials all the way "violent".Since the Spring Festival, various major products have set foot on the road of price increase, according to CCTV financial report: copper, paper, plastic, glass, zinc alloy, stainless steel skyrocketed.By the end of February, it was a massive 20%, 30% crazy jump, can be said to be all the way "violent".Compared with the beginning of 2020, the year-on-year increase of some raw materials is even more than 200%!During the two sessions, a number of industry representatives also made their voices heard. Hu Dezhao, a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), put forward a proposal on "Preventing the Rising Price of Raw Materials to Maintain Six Stable and Six Guaranty", calling on the government to regulate the market of raw materials through market mechanism and macro-control to prevent the continuous soaring price of raw materials.Among them, Xiong Jianming, chai

New steel drum hem stiffening hoop 2021-04-20

Recently, there is a new product called steel drum edge strengthening hoop, also called edge protection ring.In fact, this is a kind of non-standard steel barrel structure fittings in China, which is customized to meet the needs of some foreign export goods. But this kind of steel drum first appeared in the United States, the steel drum standard in the United States has long had this kind of type.This type was later found in standard steel drums in Japan.Say so, steel barrel coils edge to strengthen hoop, it is some product already on the international, it is our country did not popularize just.

Performance and environmental protection design of metal packaging container 2021-03-29

Abstract: Metal packaging because of its recyclable use, strong plastic, outstanding protection performance, rich color and other characteristics of the majority of consumer groups love as well as many merchants recognized.However, it is worth noting that the cost of metal packaging is relatively high, the production of energy consumption is relatively large, and not only that, the production process is extremely polluting.It is imperative to carry out cleaner production, carry on technological transformation, carry on scientific and reasonable management to the production, so as to reduce the environmental impact of metal packaging in the process of processing.In this paper, the importance of green environmental protection design of metal packaging is discussed by describing the performance of metal packaging.From the aspects of metal packaging materials, processing and design, this paper further clarifies that the concept of environmental protection packaging design will become the c
