Basic Concepts & Product Classification
Manufacturer: Shandong Zhonglian Chemical Co., Ltd.
1.Q: What exactly is silica for fire-resistant glass? A: Silica for fire-resistant glass is a general term for silicon-based functional materials specially developed for grouted insulating fire glass. It mainly includes two categories: colloidal silica (silica sol, the base material) and fumed silica (functional additive). The two work together to form a fire and heat insulation layer.
2.Q: What roles do colloidal silica and fumed silica play in fire-resistant glass respectively? A: Colloidal silica is the main base material of fire-resistant liquid, forming a continuous insulating gel layer after curing. Fumed silica acts as a rheology additive and reinforcing filler, which can adjust the viscosity of fire-resistant liquid, improve system stability, and enhance the structural strength of the insulation layer at high temperatures.
3.Q: What is the difference between silica for fire-resistant glass and ordinary industrial silica? A: Ordinary industrial silica focuses on general bonding and filling functions, with high impurities and wide particle size distribution. The special grade for fire-resistant glass has directionally optimized purity, particle size, surface charge and high-temperature phase transition performance, specially matching the optical, fire resistance and weathering requirements of fire-resistant glass.
4.Q: What are the common specification dimensions of the products? A: Colloidal silica is divided into multiple grades by solid content (30%~55%) and multiple levels by particle size (60~120nm), with two major series: general purpose grade and curtain wall grade. Fumed silica is divided into different models by specific surface area, which can be selected on demand.
5.Q: What is Class A insulating fire-resistant glass? Can silica materials support it? A: Class A insulating fire-resistant glass refers to fire-resistant glass that meets both fire integrity and fire insulation requirements, and is the mainstream category of building fire protection. This product can stably support the production of Class A fire-resistant glass with all ratings from 0.5h to 3.0h.
6.Q: Is silica for fire-resistant glass an inorganic material or an organic material? A: It is an all-inorganic silicon-based material with core components of amorphous silica and deionized water. It contains no organic resins or polymer compounds, which is essentially different from organic fireproof adhesives.
7.Q: Is it suitable for both one-component and two-component fire-resistant glass systems? A: The system based on colloidal silica is usually two-component (colloid + curing agent), and can also be formulated into a one-component slow-curing system. Fumed silica can be used as an additive to adapt to both one-component and two-component systems.
8.Q: Is the product neutral or alkaline? Why? A: Conventional colloidal silica is an alkaline system with a pH value of 9.0~10.5. In an alkaline environment, the surface of nano-silica is negatively charged, and the colloid stability is maintained through charge repulsion to prevent gelation and precipitation during storage.
9.Q: Can silica for fire-resistant glass only be used for grouted fire-resistant glass? A: It is mainly suitable for grouted insulating fire-resistant glass, and can also be used for other types of fire-resistant glass such as coated fire-resistant glass and fire-resistant laminated glass after formulation modification.
10.Q: Does Zhonglian Chemical produce its own silica for fire-resistant glass? A: Yes. Shandong Zhonglian Chemical has north and south dual production bases, and independently researches, develops, produces and sells the full series of silica products for fire-resistant glass, with full quality control from raw materials to finished products.
