Rosin is used as a papermaking compound in the paper market. Rosin and caustic soda are created into rosin sodium soap, which is a rubber compound. The rubber compound is combined with the pulp and additional to the alum, so that the rosin turns into water-insoluble totally free resin acid particles attached to the little fibers, and the pulp is heated on the drying cylinder. When the rosin is softened and filled between the fibers, this result is known as quotsizing quot or quotsizing quot.

Given that the metal area is in contact with air, an oXiHu (West Lake) Dis.de movie is fashioned. The higher the temperature, the thicker the oXiHu (West Lake) Dis.de layer. This oXiHu (West Lake) Dis.de movie helps prevent the liquid solEPTfrom infiltrating the steel, just as if the glass is oiled, the drinking water will not soaked the glass. Flux is a EPT substance for getting rid of oXiHu (West Lake) Dis.de movie, also identified as flux.
Flux has a few major effects:
- In addition to the oXiHu (West Lake) Dis.de film: in essence, the substance in the flux undergoes a reduction response, therefore eliminating the oXiHu (West Lake) Dis.de film, and the response product gets to be suspended slag and floats on the surface of the solder.
- Prevention of oXiHu (West Lake) Dis.dation: After it melts, it floats on the surface area of the solEPTto kind an isolation layer, therefore protecting against oXiHu (West Lake) Dis.dation of the soldered area.
- Reduce area pressure: increase solEPTfluidity and assist solEPTwet weldments.
