Plate washing waterSEC-668^#The main components areDimethoxymethane，It has excellent physical and chemical properties, i.e. good solubility, low boiling point and good solubility with water. It can be widely used in cosmetics, drugs, household products, industrial automotive products, pesticides, leather polish, detergent, rubber industry, paint, ink and other productsitIt has good degreasing ability and volatility, and can be replaced as a cleanerF11 and F11three and chlorine containing solvents are therefore environmental protection products that replace freon, reduce volatile organic compounds (VOCs) emissions and reduce air pollution.

Our companyJointly developed new products with scientific research institutionsPlate washing waterSEC-668^#，The main components areDimethoxymethane，After being put on the market, it has been welcomed by users.
Will nowhisThe physical and chemical properties, uses and precautions of are introduced as follows:
1. Physical characteristics
Molecular formula:CH_threeO-CH_two-OCH_three
Molecular weight:seventy-six point zero nine
Boiling point:4two.three℃
Flash point:-17.8℃
Density:d15/15，0.866；dtwo0/two0，0.861
Spontaneous combustion point:twothree7℃
Melting point:-104.8℃
Appearance: colorless and transparent liquid with smell similar to chloroform.
two．化學(xué)特性
It is relatively stable to alkali. When heated with dilute hydrochloric acid, it is easy to decompose into formaldehyde and methanol.
three．dissolution性能
Miscible with alcohol, ether and acetone; It can dissolve resin and oil, and its solubility is stronger than that of ether and acetone; The azeotropic mixture with methanol can dissolve nitrocellulose with high nitrogen content;sixteen℃When dissolved in waterQuantitythreetwo.three%（WT）；水在his中的dissolutionQuantity4.three%（WT）。
according toDimethoxymethane的dissolution特性，it可作為部分鹵素?zé)N溶劑的代用品；與許多溶劑的互溶性好，尤his是與LPG and DME have good compatibility and low boiling point, which is very beneficial to improve the vapor pressure and atomization rate of aerosol;AgainExcellent water solubility,Water washable polyester for convenient products。
4. Purpose

Application in the formulation of cleaner for electronic equipment. At present, it is mostly used in productionF11及F11three作主要原料，隨著氟里昂的禁用，亦將被Such productsReplaced by.
5. Precautions
Methylal isLow boiling pointFlammable liquid, non corrosive to metal, can be stored in iron, mild steel, copper or aluminum containers. Due to high volatility and low boiling point, attention should be paid to the fire source and heat source, and stored in a cool place.
