1. Sodium Carboxymethyl Cellulose(CMC) for Ceramic/Porcelain Industry
Sodium Carboxymethyl Cellulose is widely used in ceramic industry.
Sodium Carboxymethyl Cellulose can be used as excipient and intensifier of the blank in ceramic industry, Sodium Carboxymethyl Cellulose can enhance the blank, a breakage rate if producer added suitable quantity of into the blank. In ceramic material, CMC can improve the glaze slurry, a flow and increase the smoothness and improve the quality of glazed surface.
Our brand "YUYU" CMC is taken as blank adhesive, plasticizer, glaze suspending agent and color fixing agent in porcelain/ceramic industry. Adding CMC to blanks will enhance blank adhesiveness (making it easily formed), have no residue, improve mechanical strength and reduce blank breaking rate. Adding CMC to glaze will enhance the binding of blanks and glaze, promoting glaze dispersion.

5.Products
1) Specialized for low-viscosity spray granulation
Recommended model: FH6-1
Viscosity range: 10-50
Key characteristics: Small particle size, excellent water solution fluidity, uniform atomization, low ash content, minimal post-burning residue
Typical application scenarios: Ceramic powder spray granulation: Used as a granulation binder to enhance particle strength, improve powder fluidity, and provide good lubrication during green body pressing
2) Medium-low viscosity body reinforced
Recommended models: FH6-2, FVH6-1
Viscosity range: 50-500
Key features: Provides basic bonding strength, effectively enhances green body dry strength without compromising slurry fluidity
Typical applications: Floor/wall tiles. Application: Added during slurry preparation to improve green body strength after pressing, reducing damage during transportation and glazing
3) Medium viscosity general-purpose glaze paste type
Recommended models: FVH6-2, FVH6-3
Viscosity range: 1,000-2,000
Key features: Excellent water retention and moderate rheological properties, providing the glaze paste with superior thixotropy for smooth and even surface after application
Typical applications: Surface glaze/underglaze. Application: Suitable for spray glazing and immersion glazing processes to prevent rapid drying and cracking of the glaze paste, ensuring uniform surface and high gloss
4) Medium to high viscosity suspension stabilizer
Recommended models: FVH6-4, FVH6-5
Viscosity range: 2,000-3,500
Key features: Molecular chains form a stable three-dimensional network structure, effectively suspending heavy glaze components (e.g., frit, zircon sand)
Typical applications: High-density glazes, crystalline glazes, and metal glazes – prevents rapid sedimentation of heavy components, ensuring stable glaze paste concentration during application
5) High-viscosity printing paste for special applications
Recommended models: FVH6-6, FVH6-7
Viscosity range: 3,500-5,000
Key features: Exceptional water retention and pseudoplasticity. The viscosity decreases under printing shear forces to facilitate screen passage, then rapidly recovers after static to prevent bleeding
Typical application: Ceramic printing paste (roller printing, screen printing) – ensures sharp, clear patterns without spreading or clogging screens, ideal for fine pattern printing
6) High-viscosity, high-water-retaining, spray-applied glaze
Recommended models: FVH6-8, FVH6-9
Viscosity range: 5,000-7,000
Key features: Exceptional water retention. When applied to dry substrates, it locks in moisture, allowing the glaze to level thoroughly and minimize pinholes
Typical applications: Large plate/rock slab glazing. Effectively addresses common issues like pinholes and orange peel effects in large thin plate glazing, enhancing the glaze's surface texture
7) High-purity, premium-grade ceramics for specialized applications
Recommended model: (Derived) Ceram-Pure 6000
Viscosity range: 6,000-8,000+
Key features: Based on FVH6-9/10, it additionally controls ash and iron content (Fe≤0.01%) with no post-firing impurities
Typical applications: Premium bone china, fine daily-use porcelain, and artistic porcelain – ensuring a crystal-clear glaze free of small black spots or impurity defects
8) Instant soluble ceramic grade
Recommended Model: (Derived) Ceram-Instant 4000
Viscosity Range: 3,000-5,000 Key Features: Surface-treated for rapid water dispersion and dissolution, eliminating prolonged aging. Ready-to-use when added directly to slurry
