The invention relates to a scaling powder, especially applying to the alloy's department such as SnAgCu, SnAgCuRE and SnAg and so on. The quality percent of the present invention is the activation dosage of the organic acid which consists of the duality acid, the three-member acid, the hydroxyl acid, the balminess acid in the fattiness race 4-30wt%,the changed capable colophony which is one or more mixed of the converged colophony, the hydrogen sulfide colophony and the divergent colophony 29-67wt%, the becoming electuary which is one or more mixed of the assembled glycol2000,the assembled glycol4000 and the assembled glycol6000 1-20wt%,the olefin as the tranquilization dosage 0.5-8wt%,the touched and altered dosage which one or more mixed of the hydrogen sulfide castor oil and the compound of the acyl and amine 1-8wt% and the remain is the impregnant of the high boiling point which is one or more mixed of the butyl dissolved fine dosage, the calorie certain alcohol of the cymene and the calorie certain alcohol of the second radicle. The invention doesn't contain the halogen and penetrate the copper mirror after welding. It has high insulated resistances, the excellent function of the assisting burning. Also it solves the problem of oxidation in the high temperature and the appropriate viscosity of the welding cream.

The present disclosure is directed toward solutions, transparent films prepared from aromatic copolyamides, and a display element, an optical element or an illumination element using the solutions and / or the films. The copolyamides, which contain pendant carboxylic groups are solution cast into films using cresol, xylene, N,N-dimethylacetamide (DMAc), N-methyl-2-pyrrolidinone (NMP), dimethylsulfoxide (DMSO), or butyl cellosolve or other solvents or mixed solvent which has more than two solvents. When the films are thermally cured at temperatures near the copolymer glass transition temperature, after curing, the polymer films display transmittances >80% from 400 to 750 nm, have coefficients of thermal expansion of less than 20 ppm, and are solvent resistant.

The invention discloses base liquid of synthetic base drilling fluid, which comprises the following raw materials, such as limonene, bipentene, butylcellosolve, alkyl polyglucoside, alcohol ether carboxylate, white oil and dimethyl silicon oil. The base liquid combines the advantages of an ether group and alpha-olefin base liquid, makes up the defects of a single component and has little influence of viscosity by the change of temperature and wide application range; the selected raw materials almost do not contain aromatic hydrocarbon and have lower cost; and the base liquid of the synthetic base drilling fluid not only has low production cost but also has good biodegradation performance and environmental friendliness, can adapt to the wide acid-base condition and has favorable surface activity, lubricating performance and chemical stability.
