③The surface of white carbon black has strong hydrophilicity (carbon black is hydrophobic). In particular, the precipitation method silica has more micropores on the surface and has stronger hygroscop......
2021-02-03① The more obvious difference is the different colors. Silica is white and can be used to make various colored products and transparent products: while carbon black can only be used to make gray and b......
2021-02-03(3) Performance difference ① Fumed white carbon black Advantages: good reinforcement, high tensile strength and tear strength, good abrasion resistance, hardening faster than precipitation me......
2021-02-03(2) Difference in basic physical parameters: Precipitation white carbon black contains water of crystallization, so it is also called hydrated silica (SiO2·nH2O). Silica, the content is 87%~95%,......
2021-02-03(1) Difference in manufacturing method: The white carbon black produced by the gas phase method and the white carbon black produced by the precipitation method are essentially the same, and the chemic......
2021-02-03The process of making leather is quite complicated and cumbersome, from naked skin to finished leather, it needs to go through many processes. Before tanning, preparations for soaking in water, soakin......

2020-04-13The effect of clothing care agent (fabric softener) and laundry detergent on clothing is fundamentally different. (1) The washing liquid is to separate the dirt from the clothes, and the detergent it......
2020-04-13The main reaction for the synthesis of cationic surfactants is N-alkylation, in which tertiary amines react with alkylating agents to form quaternary ammonium salts. This reaction is also called quate......
2020-04-13Most of the commercially-available cationic surfactants are derivatives of organic nitrogen compounds, and their positive ion charges are carried by nitrogen atoms, and some new cationic surfactants h......
2020-04-13Foam plays an important role in the washing process. Foam refers to a dispersion system in which gas is dispersed in liquid or solid. Gas is the dispersed phase, and liquid or solid is the dispersion ......
2020-04-09Common emulsions, one phase is water or aqueous solution, and the other phase is organic matter immiscible with water, such as grease, wax, etc. The emulsion formed by water and oil can be divided int......
2020-04-09The surface pressure of the adsorption membrane: the surfactant adsorbs at the gas-liquid interface to form an adsorption membrane. For example, a frictionless movable float is placed on the interface......
2020-04-09①Surface tension The shrinkage force of any unit length of the liquid surface is called surface tension, and the unit is N • m-1. ②Surface active and surfactant The property that can reduce the s......
