Q:What are the uses of chlorinated vinegar?
The main highlight of application: PVC PU ink, composite packaging ink, wood paint, plastic paint, pharmaceutical packaging heat sealing glue, anodized aluminum, shoe coating, conductive silver paste, aluminum foil, aluminum foil, ink varnish nail glue, ECO ink, PU industry etc.. Kunshan pan high chemical production of two yuan, three yuan chlorine vinegar, the performance is good, can be completely ester soluble, and the price is also affordable. Landlord can try!
Q:Why multistage dilution is used in the later production process of resin?
The reference formula of phenolic resin curing agent NL alcohol quartz powder phenolic mastic - 56 - 10150 - 1000 - 56 200 glass steel putty 1000 - 10120 - 200 - 1510 - 100108 glass steel material at 1520 DEG NL dosage was 8%, 1 hours of initial setting, 30 minutes: pay attention to the use of formula of phenolic resin and furan resin NL curing agent to cure, high requirements for packing requirements, acid packing standard. Inferior fillings contain calcium carbonate, which react with acid curing agents to produce bubbles, which affect the quality of the products and may cause the resin to be unstable. Packaging and storage of 10Kg, 25Kg plastic drums. Airtight storage at room temperature. Can long-term storage, more than one year retest qualified, can continue to use.
Q:What are the similarities between the structure and the chemical composition of polymer resins?
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer.
Q:What can be used to make phenolic resins not so thick?
But there are certain toxic and volatile phenolic resin, in addition to doing very directly to bakelite plate dilution, wear a mask to do protective measures, health first. Hope to be of some help to you.
Q:What's the difference between a mixed base and a resin base band?
Hybrid base ribbon: both high quality printing and durability, wide range of applications, good price effect. High adaptability, scratch resistance, applicable materials: copper, paper, clothing, tag.
Q:Does phoenix brand 6101 and EP hardener mix with fever? What type of epoxy resin has a strong adhesion on PVC?
Phoenix brand 6101 epoxy resin, that is bisphenol A epoxy resin E44. When the epoxy resin matches with the curing agent, it will definitely release heat, and the heat is divided into mixed heat and reaction heat.
Q:Difference between vacuum pouring dry type transformer and epoxy resin casting dry type transformer
Vacuum pouring dry type transformer and epoxy resin casting dry type transformer should not have qualitative distinction, use all is insulation. At present, the vast majority of dry type transformers in the market are vacuum epoxy resin casting dry-type transformers, which are seldom poured by other insulating materials.
Q:Is there a flame retardant epoxy?
According to the characteristics of its combustion, the halogen containing flame retardant suitable halogen containing flame retardant is produced high active radical trapping agent in the combustion process, can effectively prevent combustion in the gas phase. At present, the flame retardant grade high molecular weight epoxy resin production, it will be a good prospect of reaction type of flame retardant. Generally, flame retardant epoxy resin is prepared by raw materials with flame retardant containing phosphorus and bromine containing synthesis. The phosphorus element in the skeleton structure of epoxy resin can improve the thermal stability and flame retardancy. The general raw material has four phosphate, tetrabromobisphenol A and so on.
Q:What's the function of ion exchange resins for water treatment?
The use of mixed resin resin and cationic anionic resin can remove all anions and cations leaving only water molecule ion exchange
Q:Is anion cation exchange resin dangerous?
Anion exchange resin is dangerous waste. According to the standard of hazardous waste and the standard of identification of hazardous waste: after the ion exchange resin is saturated, the acid and alkali are used to wash back, and the backwash waste water contains heavy metals, acids and bases, which is a dangerous waste.
