随着医药、食品、高纯精细化工行业对生产设备洁净度、介质兼容性要求持续升级，传统钴蓝色搪玻璃釉料逐渐难以满足行业更高标准工况需求。
我司全新研发GP-5B搪玻璃白釉正式面世！产品各项性能全面满足GB/T25025-2025搪玻璃设备国家标准，产品为高端工况提供洁净、安全、稳定的搪玻璃防护方案。
GP-5B理化性能数据如下
【GP-5B白釉核心优势】
◆耐碱性能表现突出
相较常规釉料耐碱腐蚀能力有明显提升，适用碱性介质反应工况，拓宽设备使用边界。
◆低重金属析出，洁净表现突出
釉料配方不含钴、镍、铜等重金属着色组分，重金属迁移量控制在较低水平，可有效降低金属杂质污染隐患。
适配医药原料、食品加工、浅色高纯精细化工生产，从源头减少金属杂质污染风险。
◆无有色离子溶出，改善物料变色问题
摒弃钴系着色体系，无有色离子析出情况，可改善浅色中间体、香料、高纯化学品加工过程中物料变色问题。
◆适配光化学反应工艺
白色釉层不会选择性吸收可见光，保障釜内光照通量，是光催化、光合成反应搪玻璃设备适配釉料。
◆可视性良好，便于过程管控
白色瓷层底色干净，透过视镜可清晰观察物料分层、结晶、悬浮物、色泽变化，方便操作人员实时监控反应状态。
◆便于开展清洁验证
物料残留、水垢、污渍在白色釉面辨识度高，适配 GMP 体系 CIP 清洁验证要求，适合制药、食品规范化生产车间。

Introducing GP-5B: High Alkali-Resistant White Enamel: Specially Developed for Pharmaceutical, Food & Fine Chemical Equipment
As the pharmaceutical, food, and high-purity fine chemical industries continue to demand higher standards of equipment cleanliness and media compatibility, conventional cobalt-blue glass-lined enamel is no longer sufficient for many high-end processing applications.
We are pleased to introduce GP-5B White Glass-Lined Enamel, our latest innovation designed for high-performance glass-lined equipment. GP-5B fully complies with the performance requirements specified in GB/T 25025-2025, the Chinese National Standard for Glass-Lined Equipment, delivering reliable corrosion protection and exceptional cleanliness for critical processing environments.
Physical and Chemical Performance Data of GP-5B
Key Advantages of GP-5B White Porcelain Enamel
◆ Outstanding Alkali Resistance
GP-5B offers significantly improved resistance to alkaline corrosion compared with conventional glass-lined enamel. Its enhanced durability makes it suitable for processing alkaline media while broadening the operating range of glass-lined equipment.
◆ Low Heavy Metal Leaching for Enhanced Product Purity
GP-5B is formulated without cobalt, nickel, copper, or other heavy-metal colouring components. Heavy metal leaching is maintained at a very low level, helping minimise the risk of metallic contamination.
This makes GP-5B particularly suitable for pharmaceutical manufacturing, food processing, and the production of light-coloured, high-purity fine chemicals where product cleanliness is essential.
◆ No Colored Ion Dissolution, Preventing Material Discoloration
By eliminating cobalt-based coloring systems, GP-5B prevents the release of colored ions, effectively reducing discoloration issues during the production of light-colored intermediates, fragrances, and high-purity chemicals.
◆ Optimized for Photochemical Reaction Processes
The white enamel surface minimizes visible light absorption, allowing more efficient light utilization inside the reactor. GP-5B is therefore well suited for glass-lined equipment used in photocatalytic and photochemical synthesis processes
◆ Excellent Visibility for Process Monitoring
The clean white enamel surface allows operators to clearly observe material stratification, crystallization, suspended solids, and color changes through the sight glass, enabling real-time monitoring of reaction conditions.
◆ Facilitates Cleaning Validation
Residues, scale, and surface contamination are much easier to identify on a white enamel surface. GP-5B supports GMP-compliant CIP cleaning validation and is well suited for pharmaceutical and food manufacturing environments where hygienic standards are critical
Recommended Applications
