Yantai imported PUR glue complaints yantai PUR glue complaints 1, moisture during maintenance PUR reactive polyurethane hot melt adhesive
machine before work, must first put PUR moisture reactive polyurethane hot melt adhesive on the mechanical power and connection outside the total power to cut off, shall not be charged.
5, good quality hot melt adhesive with heat resistance performance, can put the hot melt adhesive in zero or more than 40 degrees respectively environment for testing, if there are brittle, soft gelatin said quality is bad now.
Can be divided into two components of catalytic curing, one-component UV curing or thermal curing.
At present good quality hot melt adhesive can be used in the field of industrial manufacturing, heat resistance performance and flame retardant performance is guaranteed, the current can reach the quality requirements must be big brand products, such as ke, Moore, focus on the study of the hot melt adhesive, provide customized hot melt adhesive application solutions, wide range of USES, can be applied to new energy, military industry, aviation, shipbuilding, electronics, automobiles, instrument, power supply, high iron, and other areas of the industry.
Catalyst choice not only depends on the type of monomer, and also depends on the adhesive drill agent USES.
This kind of resin is the main components of the production of hot melt adhesive, the proportion of basic resin, quality determines the basic properties of the hot melt adhesive, (
Such as adhesive bonding ability, melting temperature and the cohesive strength)
18 - generally choose the VA content
33, refers to (
800, VA low content, the crystallinity, the higher hardness, same case VA content, crystallinity and low elasticity, the choice of EVA melt refers to is also very important, the smaller fusion refers to illiquid strength high melting temperature of the adhesive wetting and permeability is quite poor.
Although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive.
1, EPE packaging industry, electrical appliances, shockproof anti-throw EPE packaging materials packaging assembly parts, electrical appliances manufacturer for rubber end users without peculiar smell, and in the production of EPE packaging manufacturer assembly process, coating machine is open, a local heating temperature is high, production workers allergic to special smell, think there's a smell is poisonous, the influence is healthy, require a safe working environment, so the smell of extremely strict requirements are put forward for hot melt adhesive, require hot melt adhesive has no smell.
Yantai import PUR glue complaints test principle for 25 mm in width and thickness of 0.
Two-way stretch polypropylene film)
Membrane evenly coated with a layer of adhesive solution, in the oven drying under 100 ℃ for 5 min, then take place after 30 min wash paste in the drying of stainless steel sheet, with heavy compaction, and then in the oven drying under 50 ℃ for 5 ~ 7 min.
2, sanitary products industry: in recent years, the baby diapers, sanitary napkin, adult MATS and other health care products industry puts forward very high requirements on the smell of hot melt adhesive, require hot melt adhesive has no smell.
Along with the development of society and economy, people more and more rich, the quality of our products have higher requirements, combined with the present status of a Chinese have only one child, who all hope that their children can enjoy the treatment, even if the baby diapers, also hope that the children can use safety, and the smell of the product is absolutely not acceptable.
So in order to cater to the terminal customers, health supplies manufacturers require health supplies of raw materials manufacturers of materials, which is understandable.
Flexible can be good to very good, the weather.
Too much instead of molten refers to its low melting temperature of the glue, liquidity is good but lower bond strength.
Yantai import PUR glue complaints good electrical properties, has high drop strength.
