A "vinyl chloride in-situ polymerization of polyvinyl chloride" technology is causing widespread concern in the global PVC (polyvinyl chloride) industry
.
It is Dr.
Gao Yuhai, member of the Expert Committee of China Chlor-Alkali Industry Association and chairman of Qingdao Amos Resources Technology Co.
, Ltd.
, who has promoted the "in-situ polymerization of polyvinyl chloride" technology to the international advanced level
.
"The degree of breakthrough in the thermal stability of PVC resin represents the degree of industry development.
The core of the global PVC industry's competition is who can take the lead in controlling the thermal stability of PVC resin congenital defects
.
This is a difficult problem
.
In terms of volume, China's PVC industry started late.
In the early 1970s, China's total resin production capacity was less than 10,000 tons.
Since the reform and opening up, China has ushered in the rapid development of the PVC industry.
In 2018, China's PVC production capacity accounted for the world's total production capacity in the same period.
production capacity is nearly half
.
This has caused China's PVC industry to fall into a "bottleneck period" for a time
.
To this end, for several years, Dr.
Gao Yuhai led his team to overcome difficulties.
The "in-situ polymerization of polyvinyl chloride" technology they developed enables the production of suspension polymerization of PVC resin.
The efficiency is increased by 10%, and the thermal stabilization time of the resin at 160°C is increased to 7~35 minutes, which can be selected arbitrarily, creating the dual technical advantages of energy saving, emission reduction and green environmental protection
.
The largest PVC manufacturer in China believes in the test report of this technology that the key to this technology is to overcome the shortcomings of similar products that are unstable, difficult to store, and inefficient.
The advantages of transformation, the produced resin products have the outstanding characteristics of high thermal stability, high fluidity and other indicators
.
At the beginning of this year, Dr.
Gao Yuhai was invited to the United States for technical exchanges.
In October of the same year, he visited leading companies in major markets in East Asia.
The local PVC companies showed strong interest in this technology and gave high recognition, and are negotiating cooperation.
.
Gao Yuhai said that the field of PVC polymerization has always been monopolized by foreign technologies.
China's "in-situ polymerization of polyvinyl chloride" technology is going abroad and exported, and it will become China's first reverse export of PVC synthesis technology.
.
As a result, China's PVC industry will enter a new era of quality and competitive confidence
.
