Q:What are gypsum powder reinforced resins?
Humic acid sodium 0.3~0.5%, building material fiber waste liquid 10~12%, papermaking waste liquid 7.2~15.7%. Preparation and application of the above prepared aqueous solution, according to the ratio of gypsum and water ratio of 1:1.25-1:1.45 added to gypsum powder, after mixing good fluidity, pH control between 7.5~8 as appropriate, gypsum products into humic acid and its salts than gypsum molding water modulation flexural strength increased by 1.35~1.97 times, the compressive strength increased by 1.31~2.23 times.
Q:What's the difference between pure cotton and resin?
Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin. Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Q:What is the ratio of epoxy mortar?
Processing glass cloth. Glass cloth generally adopts glass fiber woven E-glass roving cloth, for. Glass cloth in the production process were added as wetting agent, wetting agent containing grease and wax combination epoxy liquid and glass cloth, so it is necessary to remove oil wax treatment on the epoxy glass cloth, glass fiber in the immersion liquid, improve the bonding effect. Method for removing wax glass cloth is placed in boiling water in the glass cloth 1H, then rinse with water.
Q:How can low molecular polyamide resin be used?
200 low molecular polyamide used as a toughness curing agent for epoxy resin adhesive. The reference dosage is 50~100 parts. The curing conditions are /7d or 65 /3h at room temperature. When the E-51/200=100/55 (mass) 25~O cured 7d, the thermal deformation temperature was 77~80 DEG C; if E-51/200=100/50, adding 3.8 parts of two amino benzene, 150~C/4h curing, the thermal deformation temperature of the cured material was 104~C. Heating and curing can effectively improve the physical and mechanical properties of the cured products. For example, the cured parts 23~C/16h+100~c/2h, the thermal deformation temperature of the cured products is 118 degrees, and the tensile strength is 32MPa. 200 low molecular polyamide is also used as tackifier for PVC sols. It can be used as epoxy resin curing agent, epoxy resin 100 parts, low molecular polyamide resin 100--150 parts
Q:Who knows where the pine resin should be sold? What is the general market price? Consult your experts.
A resin secreted by pine trees; called turpentine. From a chemical point of view, rosin is mainly a solution formed by solid resin acids dissolved in terpenes.
Q:What is the difference between polyester and resin?
Resins are natural substances, while polyesters are synthetic.
Q:Why should the new resin be disposed of? How do we deal with it?
Specific treatment methods include:(1) treated with salt water;Salt water solution 10%, approximately equal to the volume of resin treated 2 times to soak for 20 hours or more, and then put salt water, with water rinse, drain water with yellow. If the impurities and fine resin powder should be rinsed clean.(2) treated with dilute hydrochloric acidWith 2%, a 5% concentration of HCl solution, about equal to 2 times the volume of resin treated, soaked for more than 4 hours, and then put the acid solution, washed with water until neutral.(3) treated with dilute sodium hydroxide solution, with 4% NaOH solution, approximately equal to 2 times the volume of resin treated, soaked for 4 hours, and then put lye, washed with water until neutral.
Q:What kind of resin is AC resin (AC as raw material for the production of glasses lenses)?
Infrared: PMMA allows infrared rays less than 2800nm wavelengths to pass. The longer wavelength IR, which is less than 25000nm, is substantially blocked. There are special colored PMMA that allow specific wavelengths of IR to pass through while blocking visible light (for remote control or thermal stress, etc.).
Q:What is the difference between resin and acrylic material?
The resin is unsaturated polyester resin and belongs to thermosetting plastics. Produced by liquid resin and hardener. Unsaturated polyester resin is generally with ester bond and unsaturated polymeric compound from unsaturated dicarboxylic acid or unsaturated dicarboxylic acid diol diol condensed.
Q:The difference between resin and plastic
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials.
