Q:What are the uses of UV curable resins?
UV light cured resin light green transparent liquid, without adding curing agent and accelerant coating, coated with exhaust billowing coating type construction, into the UV UV lamp under UV light irradiation for 3-6 minutes, can be completely cured. After curing, the hardness is high, the construction is simple and economical. The glue without UV light can be reused.
Q:The difference between epoxy resin and plastic
Plastics can be classified into thermosetting plastics and thermoplastics. Thermosetting plastics are plastics that are cured under heat or other conditions, which are heated and will not melt and are insoluble in solvents
Q:Is EVA resin harmful to human body?
The characteristics of EVA resin with good flexibility, rubber like elasticity, at -50 degrees still can have good flexibility, transparency and good surface gloss, good chemical stability, anti aging and ozone resistance, good strength, non-toxic. With the filler of good mixing, coloring and molding processing good.
Q:Is there a flame retardant epoxy?
Such as: EX-48 brominated epoxy resin containing high bromine flame retardant, especially suitable for paper base, cloth laminated board, but also can be used as flame retardant thermoplastic plastic and rubber products. Also according to the requirements of the user to prepare epoxy resin special bromine content.
Q:What's the difference between resin clay and super light clay? I'm a newbie. I want to make my own hand puppet. That will work better
Most color is white, can be the author of the color of hope. But the colored clay in after drying, the color will become strong, the best to do a test first master component. Without baking, in the air can be dried. The dried product surface smooth. A high degree of simulation. The fine soil, to make dolls dry grinding processing, dry hard, flower will thin flower as if toughness. Finished in general with the hair brush to dust on the line, can be washed with water, but not used blisters.
Q:What is bakelite?
The phenolic resin is of great polarity and has good adhesion to metals and most non metals, and the adhesive strength is higher. Due to the existence of a large number of benzene rings in phenolic resins, they can be cross-linked into a body structure, which has higher rigidity, high heat resistance, creep resistance, ablation resistance and good dimensional stability.
Q:Classification of resin flakes (by refractive index)
High refractive index generally refers to refractive index of more than 1.60, mainly by MR series monomer and the introduction of sulfur and phosphorus atoms of acrylic series monomer processing.
Q:Lighting industry to do the lamp rack, there are many resin materials used, I ask what kind of material in the end, what are the advantages?
Strictly speaking, is a chemical phenolic resin structure, there are many types, widely used in light industry and heavy industry in our daily life, we often come to, such as plastic, resin lenses, coatings, rosin.
Q:Is it harmful to human beings to drink water with resin?
Acrylic pigments are popular with painters. It has the following characteristics:(1) water can be used for washing.(2) quick drying. The pigment in the pen after a few minutes to dry, do not have to wait a few months to finish to be like painting as glazing. Painters who prefer slow drying pigments can use retarders to retard the drying time of pigments.(3) the coloring layer will lose its solubility rapidly after drying, and form a tough, elastic film without water seepage. This film is similar to rubber.(4) full color, dense, fresh and smooth, no matter how to reconcile, there will be no "dirty", "gray" feeling. The coloring layer will never be contaminated by oil absorption.(5) the permanence of the works is longer. Oil painting in the film for a long time, easy to oxidize, yellow, hardened, easy to cause cracks in the picture. The acrylic film will never be brittle in theory and will never turn yellow.(6) the biggest difference between acrylic pigment and oil painting is the operation characteristic of general water pigment, which can be used as watercolour and gouache.(7) the acrylic molding ointment contains granules, with coarse particles and fine particles, which is convenient for making skin texture.(8) acrylic paint non-toxic, harmful to the human body.
Q:What is the concept of BV when dealing with resins?
Industrial resin column bed volume usually from 1 to 10m3, also have smaller or larger. This is the basic unit of resin column, and the amount of material it works with is BV.
