The national standard of laundry detergent production equipment manufacturers on laundry detergent

Cloth with QB/T1224 - liquid laundry detergent 1991 'material with a liquid detergent' is the national light industry standard, belongs to the voluntary standards, on April 1, 1992. This standard specifies the technical requirements for material with a liquid detergent, test methods, inspection rule and marks, packaging, transport and storage conditions. Stability: the main technical indicators are as follows: in the 24 hours to 40 ℃ + 2 ℃ temperature stratification; - 5 ℃ + 2 ℃ temperature for 24 hours, restores to 15 ℃ to 25 ℃ stratification, no precipitation. This index is mainly to investigate the stability of product performance and storage performance. Required to anionic surfactant detergent surfactant content not less than 15%, non-ionic detergent surfactant content not less than 10%. The surfactant is mainly plays a role of decontamination and foaming detergent ingredients, is a kind of surface active compounds, the compound molecule containing at least one of significant surface polarity has affinity groups ( Determines the molecular hydrophilic characteristics) And a little to water affinity of nonpolar groups ( Determines the molecular characteristics of oil-wet) , it is easy to dissolve in the water. Due to the surface of the liquid/gas or other preferential adsorption interface, surface tension and interfacial tension decreased significantly, thus the dirt from the carrier up to and dissolve into the solution. The discretion of the total active matter content is an important indicator of success for the quality of liquid detergent, generally speaking, high content of total active matter in detergent quality is relatively good. Some fake products is cutting corners on this indicator. PH: cotton and chemical fiber with detergent ( 1% of the aqueous solution) The pH value is not more than 10. 5. Silk wool detergent ( 1% of the aqueous solution) The pH value of 6. 0 to 8. 5. Is washing dirt heavier cotton and chemical fiber with alkaline detergent can to a certain extent, and catharsis silk wool used would have to be neutral, to reduce the damage to the fabric. Bubble: requirement is greater than 300 ml. In general the bubble liquid detergent is rich, but the bubble too much is not easy to rinse, so products are required to have certain defoaming performance, to facilitate the rinse water. Relative BiaoZhunFen decontamination ratio: the requirement is not less than 1. 0. Washing supplies decontamination ability cannot be measured by means of direct measurement, so a kind of standard of national standard of washing powder, made by enterprises designated by the according to the formula of fixed production, as a physical standard for the determination of detergency, will other decontamination effect and the comparison of washing supplies, draw a ratio ( Is the equivalent of BiaoZhunFen detergency multiples) To measure the detergency of products. Detergent powder making machine dishwashing machine next article: laundry detergent and other cleaning products matters that should be paid attention to the production of an article: laundry detergent, soap powder, washing powder using on what's the difference?
