Industrial Grade Chemical Powder Sodium CMC Paper-maiking
If the film transfer metering sizing press is used, the 20/30/50 viscosity should be selected when Sodium CMC is used with denatured starch. When CMC Polymer is used as a sizing agent alone, the viscosity can be selected according to the sizing amount (glue concentration). In short, the film transfer metering sizing press should choose a lower viscosity CMC Powder, which should be determined for different machines, different paper types and different sizing requirements. Like some water-resistant, wet strength paper with special requirements, such as securities paper, banknote paper, water pine base paper, release base paper, decorative paper, advanced double-adhesive paper, drawings, trademark paper, etc., should be matched with an appropriate amount of water resistant agent to make it crosslinked with starch and CMC Chemical and other materials in the formula to form a water resistant film. The addition amount can generally be controlled at 0.5-2.0 grams (to the cross-linked rubber dry solid amount of 100 grams). If necessary, it can also be used with modified melamine formaldehyde resin.
