Description

Industrial Gelatin is light yellow or brown grain, which can pass the 4mm aperture standard sieve. The product is under the QB/T******4 national trade standard. We can handle the SGS, ITS quality certificate and CIQ veterinary sanitation certificate and the note for changing the certificate of letting pass. Coating and Sizing Technical gelatins are used in the warp sizing of rayon and acetate yarns. The gelatin size adds strength to the warp and resistance to abrasion so that breakage of the warp is minimized. Gelatin is particularly well suited for this application because of its excellent solubility and film strength. It is applied in aqueous solution along with penetrating oils, plasticizers and antifoam agents before weaving, and later removed during finishing by washing with warm water. Paper Manufacture Gelatin is used for surface sizing and for coating papers. Either used alone or with other adhesive materials, the gelatin coating creates a smooth surface by filling up the small surface imperfections thereby ensuring improved printing reproduction. Examples include posters, playing cards, wallpaper, and glossy magazine pages. Printing Processes For over a century, gelatin compositions have been used in printers&#**9; rollers and plate wiping rollers for multicolor presses and offset lithography. Several photo-printing methods depend on the effect of light on a gelatin film which has been sensitized by treatment with potassium or ammonium dichromate. Examples of printing applications include carbon printing, collotype printing, silk screen printing, and photogravure printing.
