The main uses of hydroxypropyl methylcellulose (construction industry):
1. Cement mortar: improve the dispersibility of concrete sand, greatly improve the ductility and water solubility of cement mortar, prevent cracks, and improve cement strength.
2. Tile cement: improve the plastic deformation of floor tile cement mortar, maintain water solubility, improve the compressive strength of tile adhesives, and avoid delamination.
3. Apply asbestos and other refractory insulation materials: as a floating agent, it improves fluidity and also improves the hot-joint compressive strength of the substrate.
4. Cooked stone concrete slurry: improve its water solubility and production and processing characteristics, and improve the adhesion of the substrate.
5. Joint cement: add gap concrete to the paper-faced stone board to improve fluidity and water solubility.
6. Latex mud: natural latex oil uses epoxy resin natural latex as raw material to improve fluidity and water solubility.
7. Plaster: as a slurry to replace pure natural chemicals, it can improve water solubility and improve the relay race with the base glue.
8. Paint: As a thickener for latex architectural paint, it can improve the practical operation characteristics and fluidity of architectural paint.
9. Spray paint: It has a good practical effect on preventing water leakage of fillers such as concrete systems or natural latex systems, improving fluidity and spray beam shape.
10. Concrete and cooked stone have secondary products: as hydraulic raw materials such as concrete-asbestos, press out molding adhesives, improve fluidity, and uniform molding.
11. Fiber wall: Because of its antibacterial hydrolysis effect, it is very reasonable to use it as an adhesive for exterior wall fluorocarbon coatings.
12. In addition: Foam maintenance agent (PC version), which can be used for thinner balanced glue cement mortar and masonry operations.

Dissolution method of hydroxypropyl methylcellulose:
1. All models and specifications can be added to the raw materials in a dry mixing manner.
2. When the solution needs to be added immediately at room temperature, choose the cold water dispersion type, which can generally thicken within 10-90 minutes after addition.
3. After the general models and specifications are dispersed with boiling water, add cold water and stir and refrigerate to dissolve.
4. If agglomeration and encapsulation occur during the dissolution process, it is caused by insufficient mixing or immediate addition of cold water to the general models and specifications. At this time, it should be mixed quickly.
5. If bubbles are generated during the dissolution process, they can be left to stand for 2-12 hours (the specific time is determined according to the concentration of the substance), or removed according to vacuum packaging and pressurization, or an appropriate amount of silicone defoaming agent can be added.
