Corona Virus — Another Challenge!

— Darrell J Reeve

For surface finishers, and especially powder coaters, the word 'Corona' is very significant and is basic to the electrical charging of powder particles in the cloud as it leaves the spray gun. 'This corona' is still enjoying a strong market march all over the world and is perhaps the core of the greater part of all our finishing systems in commercial use today. We all depend on the sun's corona for stable heat supply within specific limits to promote and sustain life on earth.

 

Electroplating

Innovative Zincate Electroplating Process with Application on Cast Iron

— Mr. Aijun Zhou, Mr. Lihui Sang, Mr. Xiang Li, GaoYimei Environmental Protection Co.Ltd., Guangdong, PR. China

Currently, zinc electro-plating is one of the most popular metal finishes, with benefits of good protection, low cost, easy handling and simple processing. It is widely used and is most economical for preventing the corrosion of steel. Electrochemically, the plating of zinc can protect the steel base by self sacrificing itself especially in case there are voids, layers or exposure by damage on the base. The chemical stability of zinc plating is good at ambient temperatures.

 

New Opportunities for Electroplating Industry in 2020

— Li Xiaoying, Contributing Writer

In traditional manufacturing, electroplating primarily imparts wear and corrosion protection for machines and tools. In high-tech manufacturing, it provides high-end equipment and information technology devices extra functional coatings (e.g. improving conductivity). Today, electroplating is everywhere around us, from our mobile devices, kitchen utensils, furniture, lighting, to automobiles and office equipment. In fact, technological progress of electroplating continues to expand its applications into new markets.

 

Surface Coatings Analysis

Applications of SEM/EDS in Surface Analysis

— Jing Xinxin, Shen Hui, Ma Jiaqi, Wang Tingting, Suzhou He-Chuan Chemical Technology Service Co., Ltd., P.R. China

A micro analytical technique by Scanning Electron Microscope (SEM) in conjunction with Energy Dispersive X-ray Spectroscopy (EDS) has been widely used in R&D and the manufacturing sector recently. It is of particular importance to surface treatment after passivating, such as phosphating, ceramic and trivalent chromium passivation as well as plating. SEM allows users to observe surface topography of materials, as well as to evaluate the effectiveness of surface finishing and performance of materials. EDS allows users to measure elemental composition of materials and the presence of foreign objects.

 

Market Insight

The Industry Across the Globe Met in 3 Days

SFCHINA2019, the 32nd edition of its series, concluded with a record-breaking net exhibit size on November 18-20 at the Shanghai New International Expo Centre (SNIEC), P.R. China. The exhibition results further strengthen SFCHINA's status as a great platform where surface finishing industry meets annually.

 

Trend-Setting Solution for Finishing Industry in SFCHINA2019 Shanghai

— Mr. Darrell J. Reeve, Member of Institute of Materials Finishing and Australasian Institute of Surface Finishing, AISF

Our visitors and SFJ readers were/are most interested in the new technologies and equipment on show. It is impossible in just 3 days to get around all the exhibits and appreciate all the new developments. This is especially true for exhibitors and visitors that travel great distances to be at the show.

 

Automotive Coatings

China's Car Market Slump has Bottomed Out

— Sally Yick, Managing Editor, Surface Finishing Journal

A report on December 10 issue of the Financial Times website titled „Valeo said that China's auto market has bottomed out and rebounded„, Valeo, a world's car parts supplier, believes China's car market has bottomed out after a slump that has cast a shadow over the global industry and dented profits of many manufacturers.

 

Powder Coatings

Low Temperature Thermal Cure Powder Coating for MDF

— Dr. B.P. Mallik, Mr. M.S. Rawat, Asian Paints Ltd, India

When powder coating was embraced as an alternative technology to coat metals as opposed to liquid paints, the transition was difficult but manageable. Now, having mastered the art of powder coating on metals, when powder manufacturers began to extend this technique to wood substrates it wasn't as smooth as it was expected to be. Most common problems encountered with coating of wood substrates are unique in the sense that wood, being a heat sensitive substrate, does not behave in the same way as metal.

 

Environmental Challenges

Climate Change

— Mr. Darrell J. Reeve, Member of Institute of Materials Finishing and Australasian Institute of Surface Finishing, AISF

For the Asia/Pacific region, we should all be concerned with issues such as sea level rises, glacier disappearances (over 100 in the Himalayas), city smog, water shortages, arid land increase, dramatic weather events and species extinction to name just a few of the issues involved directly and/or indirectly with climate change.
