Hidroksipropil metilceluloza

Overview of Hydroxypropyl Methylcellulose

Concreteandmore’s Hydroxypropyl Methylcellulose (HPMC) is a high-performance non-ionic cellulose ether, specially processed from natural plant cellulose. It is widely used as a key additive in concrete and mortar, with excellent thickening, water-retention, film-forming and rheological properties. Our HPMC effectively solves the problems of poor water retention, easy segregation and low workability of cement-based materials, improves the bond strength and durability of concrete/mortar, and ensures smooth construction, suitable for various construction scenarios and climate conditions around the world.

Features of Hydroxypropyl Methylcellulose

• Odlično zadrževanje vode: Effectively locks water in concrete/mortar, reduces water loss, prevents surface cracking and improves the strength of hardened materials.
• Strong Thickening & Rheological Control: Significantly improves the viscosity of cement paste, enhances cohesion, prevents segregation and bleeding, and optimizes construction workability.
• Good Film-Forming Property: Forms a uniform and tough film on the surface of concrete/mortar, improving impermeability, weather resistance and bond strength.
• Non-Ionic & Dobra združljivost: Non-ionic structure, compatible with various cement types, reduktorji vode, sredstva proti penjenju in drugi dodatki, nobenih neželenih učinkov.
• Visoka čistost & Stabilnost: High cellulose content, low impurity, stable performance in a wide pH range (3-11), nestrupen, odorless and environmentally friendly.

FAQs of Hydroxypropyl Methylcellulose

1.What is the role of HPMC in concrete?

It provides water retention, thickening and cohesion, prevents water loss and segregation, improves workability and bond strength of concrete/mortar.

2.How to choose the right viscosity of HPMC?

Visoka viskoznost (≥100000 mPa·s) for putty/waterproof mortar; medium viscosity (10000-50000 mPa·s) for tile adhesive; low viscosity for concrete.

3.How to use HPMC in construction?

Mix HPMC powder evenly with cement, najprej pesek in druge suhe materiale, nato dodajte vodo in temeljito premešajte, da zagotovite enakomerno disperzijo.

4.Will HPMC affect concrete setting time?

Proper dosage will not significantly affect setting time; prevelik odmerek lahko nekoliko upočasni strjevanje, which can be adjusted by dosage control.

5.Ali zagotavljate globalno dobavo in tehnično podporo?

ja, we supply HPMC worldwide, s popolnim TDS in strokovnim vodstvom, ki vam pomaga izbrati pravi model in odmerek.
