Hidroksipropylmetielsellulose (HPMC), wie se Chinese naam hidroksipropylmetielsellulose is, is 'n semi-sintetiese, nie-ioniese sellulose-eter verkry deur natuurlike sellulose chemies te modifiseer. Hierdie wit poeier kan 'n deursigtige viskose oplossing vorm nadat dit in water opgelos is. Dit het uitstekende verdikking, waterretensie, stabiliteit en filmvormende eienskappe. Dit is 'n onontbeerlike multifunksionele toevoeging in baie velde soos konstruksie.

Uitstekende wateroplosbaarheid: Dit kan vinnig in koue water opgelos word om 'n helder en stabiele oplossing te vorm.

Doeltreffende verdikking en waterretensievermoë: Verhoog die viskositeit van die materiaal, verminder waterverdamping effektief, en werkdoeltreffendheid te verbeter.

Goeie stabiliteit: Dit het goeie stabiliteit teen sure, alkalies, en soute, en is geskik vir 'n wye reeks pH-waardes.

Filmvormende en beskermende effekte: Na droog, dit vorm 'n taai en deursigtige film om die substraat te beskerm en waterpenetrasie en verdamping te voorkom.

Nie-giftig en nie-irriterend: Dit het goeie bioversoenbaarheid en is geskik vir die velde van medisyne en voedsel.

Verstelbaarheid: Deur die graad van substitusie en molekulêre gewig te verander, sy werkverrigting kan aangepas word om aan verskillende toepassingsvereistes te voldoen.

Hidroksipropylmetielsellulose (HPMC)– Produkspesifikasies

Oorsig

Hidroksipropylmetielsellulose (HPMC) is a white or beige powder. It dissolves in cold water to form a clear, viskose opsie. HPMC is extensively used in building, farmaseutiese produkte, kos, and cosmetics due to its excellent thickening, bindend, filmvormende, and water-retention buildings.

Viskositeit grade

HPMC is available in several viscosity grades. Each grade is named by its approximate thickness in millipascal-seconds (mPa · s) at a 2% konsentrasie in water by 20 °C. Common qualities consist of:
HPMC 400, HPMC 4000, HPMC 6000, HPMC 40000, HPMC 60000, HPMC 80000, HPMC 100000, HPMC 150000, en HPMC 200000.

Lower-viscosity qualities like HPMC 400 en 4000 are excellent for applications needing simple circulation and quick dissolution. Tool qualities such as HPMC 6000 aan 60000 offer well balanced performance for floor tile adhesives and plasters. Hoë-viskositeit tipes soos HPMC 80000 through 200000 supply strong water retention and enlarging, suitable for self-leveling compounds and specialized mortars.

Versatile Grades for Diverse Demands

Hidroksipropylmetielsellulose, of HPMC, can be found in many viscosity qualities– soos 400, 4000, 6000, 40000, 60000, 80000, 100000, 150000, en 200000. Each grade serves a specific purpose based upon its thickness and efficiency in water.

Low-viscosity qualities like HPMC 400 and HPMC 4000 mix easily into liquids. They function well in floor tile adhesives, selfnivellerende verbindings, en droëmengsel mortiere. These grades help regulate water retention so seal collections appropriately.

Medium grades such as HPMC 6000 and HPMC 40000 are common in outside insulation systems and plaster. They offer great workability and quit drooping on vertical surface areas. Home builders depend on them for smooth application and strong attachment.

High-viscosity types– consisting of HPMC 60000 , 80000 , 100000 , 150000 , en 200000 — are thick and steady. They are utilized where long open time and high water retention issue the majority of. Instances consist of thick-bed renders, herstel diens mortiere, and specialized grouts. These grades keep the mix wet much longer, which helps healing in hot or dry conditions.

Efficiency You Can Trust Fund

HPMC boosts consistency across all construction products. It avoids separation of ingredients and makes mixing less complicated. The item likewise minimizes dust during handling and boosts pumpability.

In addition to construction, some HPMC qualities sustain pharmaceutical and food usages. Yet in structure applications, the focus stays on stamina, werkbaarheid, and dependability.

Different projects require various thickness. Selecting the appropriate HPMC grade makes sure much better results– whether you’re laying floor tiles, finish walls, or fixing concrete. Constantly match the quality to your mix style and job conditions.

Gereelde vrae oor HPMC-grade

What is HPMC and why are there so many grades?

HPMC staan ​​vir Hydroxypropyl Methyl Cellulose. It is a water-soluble polymer made from plant cellulose. Different grades—like 400, 4000, 6000, up to 200000—refer to viscosity levels. Higher numbers mean thicker solutions when mixed with water. Each grade suits specific uses based on how thick or thin the final product needs to be.

Which HPMC grade works best in construction materials?

Grade soos 40000, 60000, en 100000 are common in tile adhesives, lewer, en pleisters. They give good workability, waterretensie, en oop tyd. Lower grades like 400 of 6000 are too thin for these jobs. High-viscosity HPMC helps keep water in the mix so cement can cure properly.

Can I use high-viscosity HPMC in food or pharmaceuticals?

Ja, but only if it meets food-grade or pharma-grade standards. Viscosity matters less than purity here. Grades like 400 of 4000 are often used in tablets or sauces because they dissolve quickly and feel smooth. Always check the product’s certification before using it in consumables.

Hoe beïnvloed viskositeit prestasie?

Viscosity controls thickness and flow. Low-viscosity HPMC (bv., 400–6000) spreads easily and mixes fast. High-viscosity types (bv., 150000–200000) create gels that hold shape and slow down water loss. Pick the right viscosity based on whether you need fluidity or stability.

Is HPMC veilig om te hanteer?

HPMC is nie-giftig en bioafbreekbaar. It does not irritate skin under normal use. Steeds, wear gloves and a mask when handling fine powders to avoid breathing dust. Store it in a dry place—it absorbs moisture from the air and may clump.
