In conclusion, the dissolution of cement using chemicals is a complex process that requires an understanding of both the chemical properties of cement and the reactive nature of the dissolving agents. Whether through the use of traditional acids, chelating agents, or innovative biological methods, the goal remains the same to efficiently remove cement while minimizing environmental impact and ensuring safety for workers and the surrounding ecosystem. As technology advances, new and improved chemicals for cement dissolution are likely to emerge, offering even more effective and sustainable solutions for managing one of our most utilized building materials.

Latex powder — it can improve the consistency and smoothness of the system in the wet mixing state. Due to the characteristics of the polymer, the cohesion of the wet mix is greatly improved, making a great contribution to the workability; After drying, it can provide adhesion to the smooth and dense surface layer, improve the interface effect of sand, stone and air holes, and enrich the film at the interface on the premise that the addition amount is guaranteed, so that the ceramic tile adhesive has a certain flexibility, reduces the elastic modulus, and absorbs the thermal deformation stress to a great extent. In case of water immersion in the later stage, it can also have water resistance, buffer temperature and inconsistent material deformation (ceramic tile deformation coefficient 6 × 10-6/ ℃, deformation coefficient of cement concrete 10 × 10-6/ ℃) to improve weather resistance. Youngcel Hydroxypropyl methyl cellulose HP cellulose — provides good water retention and workability for fresh mortar, especially for the wetted area. In order to ensure the smooth progress of hydration reaction, it can prevent excessive water absorption of substrate and evaporation of surface water. Due to its air entraining property (1900g/l—1400g/lpo400 sand 600HP cellulose 2), the unit weight of ceramic tile adhesive is reduced, materials are saved and the elastic modulus of hardened mortar is reduced.

  • In the pharmaceutical industry, HPMC ether is used as a binder, film-former, and sustained-release agent in tablets and capsules. It helps to control the release of active ingredients, improve the solubility of poorly soluble drugs, and provide a smooth and glossy surface for easy swallowing. HPMC ether is also used in eye drops, ointments, and gels to enhance their viscosity, improve the adhesion to the eye surface, and prolong the contact time with the cornea.

  • Cellulose manufacturers transform this natural resource into a myriad of products, ranging from paper and textiles to pharmaceuticals and food additives. The process involves breaking down the cellulose fibers through chemical or mechanical means, creating derivatives like cellulose gum, cellulose acetate, and microcrystalline cellulose. These derivatives find applications in various industries due to their unique properties, such as high viscosity, stability, and biodegradability.
