As a leading manufacturer of equipment for producing amino molding plastics, melamine molding powder and urea formaldehyde molding powder, Johnley Factory is proud to share the remarkable journey of amino molding plastics' development.
Amino molding plastics have a rich history that dates back to 1920 when the German company BASF began its research on amino resins. Just two years later, in 1922, the British company BIP introduced the first industrial product known as the "BEETLE," marking the beginning of an 80-year journey in the development of amino molding plastics.
In China, the Shanghai Tianshan Plastics Factory became the first manufacturer of amino molding plastics. The production technology was imported from the former Soviet Union in 1957 and gradually transitioned into industrial-scale manufacturing.
Over the course of more than four decades, significant improvements have been made in both the process and equipment. The production facilities in China have now approached the level of those in foreign countries.
1. The conventional cabinet dryers have evolved into advanced mesh belt dryers, which are highly automated, yield high production volumes, and offer better control.
2. The hammer-type crushershave been replaced by water-cooled high-speed universal crushers, and the ball mills now adopt water cooling, with the lining reduced from 10cm to 3-4cm of ceramic lining.
3. The arrangement of ball mills can now be both in parallel and in series, significantly increasing production capacity and reducing labor intensity for workers.
4. The resin storage tanks were minimized, and the kneader capacity was increased from 500dm3 to 1500dm3 for maintaining the freshness of the resin used.
5. With a polymerization degree of 1-3 and a molecular weight of only 20-30, the amino molding plastics are ideal for impregnating pulp and reacting with the hydroxymethyl groups in both the pulp and the resin.
6. The production capacity of a single production line has been increased from the original 2kt to 4kt.
7. Substantial improvements have been made in dust removal and ventilation within the workshop, meeting the requirements of environmental protection for dust and waste gas.
Throughout its longstanding history, the evolution of amino molding plastics has brought advancements in technology, equipment, and environmental sustainability, making them a trusted choice in various industries.
