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.
Q:How about resin glasses?
Convenient lens grinding processing, reduce the time of glasses.
Q:What are the main ingredients of PET? What's the difference between PET resin and PET?.
PET polyethylene terephthalate (PET) English Name: polyethylene terephthalate (PET), widely used as fiber and engineering plastic resin can be divided into non engineering plastics and engineering plastics in two categories, non engineering plastic grade is mainly used for bottle, film, sheet, baking food containers etc..
Q:Can the resin glasses break?
Of course, if you hit it on the ground, it will break, because it's a kind of plastic and belongs to high polymer material,The resin fragments are broken under high impact, and the hardness of the fragments is small, the edge is smaller than the glass crystal fragments, and the damage to the eyes is reduced. High standard resin goggles are the standard safety protection equipment for foreign labor protection and shooting training. (some shooting goggles can withstand 6 mm gun shooting, so positive) resin glasses can be broken, but is usually a small crack, so easy to fall on the edge.
Q:Mixed bed resin filling after stratification also need?
Pretreatment of resins1. from the bottom of the exchange column, 3~4m/h 4%HCl solution of two times the resin volume (the total amount of resin of the resin) is taken from the bottom to the bottom, and then soaked with hydrochloric acid solution in the exchange column for 4~8h.2. rinse the resin from top to bottom with clean water until the effluent pH test is about 5.3. the water level placed about 500mm resin layer, from the exchange column into the base tube, at a flow rate of 3~4m/h from the top down into the two times the volume of resin (total amount of cation and anion exchange resin resin) about 4%NaOH solution, and then use the exchange for 4~8h hydrochloric acid solution in the column.4. after alkali soaking, without cleaning, directly for backwashing, backwash start when the velocity is small, when the resin after loosening, gradually increase the backwash flow rate, the expansion rate of the resin layer in 50~70%, maintain 10min, observe whether clear stratification.
Q:What are the properties of petroleum resins and their role in the rubber industry?
Rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin.
Q:What is resin? What's it for?
Natural resin is a very high value of physiotherapy, but very difficult to use it, because they are very thick and sticky. So in aromatherapy, we will use solvent or alcohol to natural resin processed into the liquid resin can be used.The resin can not only protect and closed their wounds, and many other magical. Such as spices, used as medicine and processing of resin paint and so on. In medicine is a treasure, it can reconcile the five internal organs, the belly of the disease. Remove the root, leaf and fruit of Liquidambar tree can also be used as medicine, can pass through the wind. Arm.
Q:Classification of resin flakes (by refractive index)
1.56, is a relatively common refraction rate of 1.499 is generally not white resin coated, is not common. 1.74 and 1.76 are ultra wave high-end lenses, even if the general brand is also a few thousand dollars a pair
Q:I saw in the supermarket very delicate bowl, the material is resin, resin is not plastic, harmful to the human body?
Natural resins are of high therapeutic value, but they are quite difficult to use because they are very thick and sticky. So in aromatherapy, we use solvent or alcohol to make natural resins into liquid resins that can be used.The resin can not only protect and closed their wounds, and many other magical. Spices, herbs, paints, and so on. Resin in medicine is a treasure, it can reconcile the five zang organs, remove the disease in the abdomen. The root, leaf and fruit of Liquidambar tree can also be used as medicine, can pass through the wind.
Q:There are 80128200 models, two differences and their respective advantages
The Japanese version of model material generally are marked as cold resin cast kit cold, refers to the process of cold forming, that is to say without heating the molten material into the mold before. Other plastics (such as pvc/abs/) must be heated and melted before injection molding is possible. Resin is a resin, kit finger kit. So translating is the meaning of cold formed Cast Resin Kit, 2.8012, 8014, 8017 resin, these three kinds of resin are AB water more common model.
