Yanshan Petrochemical successfully trial-produced 6 new VAE products in May

Recently, the production and sales of VAE products are booming
.
Overcoming the impact of the epidemic, Liu Bingpo Innovation Studio of Yanshan Petrochemical Organic Chemical Plant has been working day and night to carry out the research and development of new VAE products
.
In May, a total of 6 new VAE brand products were successfully carried out for industrialization test and amplification, which met the needs of different customers for high-end VAE products, further enhanced the added value of VAE products, and effectively expanded the application scope of VAE products.
New breakthroughs have been made in creating efficiency
.

VAE emulsion (vinyl acetate-ethylene copolymer emulsion) is a water-based polymer emulsion copolymerized with vinyl acetate and ethylene as the main raw materials by medium pressure emulsion polymerization process.
It has excellent wet viscosity, initial viscosity, resistance to Shearing properties, as well as good film-forming properties, weather resistance, adhesion, broad compatibility, weak acid and alkali resistance, etc.
, are environmentally friendly adhesives with excellent comprehensive properties
.
At present, it is widely used in composite bonding of clothing, luggage, shoe materials, etc.
, as well as construction waterproofing, coatings, non-woven fabric manufacturing, paper coating, cigarette glue, tile glue, carpet adhesive, exterior wall insulation and other fields.

At the beginning of May, Yanshan Petrochemical Organic Plant carried out the industrialization test of the new water-resistant emulsion BJ-829
.
In the pretreatment stage of raw material preparation, the abnormal phenomenon of sudden high liquid viscosity affects the stability of the viscosity index of the final product
.
To this end, the members of the studio worked together to tackle key problems in this process control, which requires high precision
.

They analyzed the effective concentration of raw materials barrel by barrel, accurately controlled the amount of additives added, reasonably adjusted parameters such as temperature and reaction time in the pretreatment stage, and cooperated with the laboratory to conduct multiple condition tests and comparison adjustments of more than ten gradients.
It only took one week.
The root cause of the viscosity fluctuation was determined in time, and the batch trial production was successful on the production device, realizing the smooth production and smooth delivery of the new brand BJ-829
.
Then, according to the high-end needs of customers, they upgraded and optimized the formula in a timely manner, and tried to produce a new variety of BJ-829H with high solid content and low viscosity
.

In addition, Yanshan Petrochemical Organic Chemical Plant is also keeping an eye on the market, and in response to the specific needs of users in the fields of self-leveling mortar, it has intensified efforts to develop new VAE products and trial production, and successively carried out two high glass transition temperature BJ-702/703.
For the mass production of the new brand, the optimization of the production process conditions and mass production of the new brand with high ethylene content BJ-707H was carried out, and the special brand BJ-720 for rubber powder with high ethylene content was trial-produced.
At present, these new products have been promoted to users.
Try it out, the feedback is good
