Hidroksipropil metilceluloza (HPMC), čiji je kineski naziv hidroksipropil metilceluloza, je polusintetika, nejonski eter celuloze dobijen hemijskom modifikacijom prirodne celuloze. Ovaj bijeli prah može formirati prozirnu viskoznu otopinu nakon rastvaranja u vodi. Ima odlično zgušnjavanje, zadržavanje vode, stabilnost i svojstva stvaranja filma. To je nezamjenjiv multifunkcionalni aditiv u mnogim poljima kao što je građevinarstvo, lijek, i hranu.

Hidroksipropil metil celuloza (HPMC)– Specifikacije predmeta

Rezime

Hidroksipropil metil celuloza (HPMC) je bijelo do gotovo bijelo, prah bez mirisa. It liquifies quickly in cool water and develops a clear, debela opcija. This product is widely utilized in building, droge, hrana, and personal treatment due to its superb thickening, vezivanje, and film-forming residential or commercial properties.

Gradevine viskoznosti

HPMC is available in several thickness qualities. Each quality is called after its approximate viscosity in millipascal-seconds (mPa · s) at 2% fokus i 20 °C. Common grades consist of:
HPMC 400, HPMC 4000, HPMC 6000, HPMC 40000, HPMC 60000, HPMC 80000, HPMC 100000, HPMC 150000, i HPMC 200000.

Lower-viscosity grades like HPMC 400 i 4000 work well as binders or in applications needing fast dissolution. Tool grades such as HPMC 6000 to 60000 deal balanced performance for ceramic tile adhesives, flasteri, i premazi. High-viscosity types like HPMC 80000 to 200000 offer strong water retention and are suitable for self-leveling substances and high-performance mortars.

Trick Qualities

All HPMC grades are non-ionic and steady throughout a wide pH array (3– 11). They stand up to microbial attack and do not interact with many salts or surfactants. The gel temperature level generally falls in between 50 °C i 90 °C, depending upon the methoxyl and hydroxypropyl web content.

Skladišni prostor i rukovanje

Store HPMC in an awesome, potpuno suvo mesto daleko od vlage. Keep containers firmly closed. Avoid long term direct exposure to humid air to avoid clumping. Usage standard industrial health methods when handling the powder to limit dirt inhalation.

Primjena hidroksipropil metil celuloze (HPMC)

Građevinski i građevinski materijali

HPMC is extensively made use of in cement-based items like tile adhesives, pruža, i samorazlivajuće smjese. Grades such as HPMC 400 i HPMC 6000 enhance workability and water retention. This aids seal moisturize appropriately and minimizes fracturing. Higher-viscosity kinds like HPMC 100000 ili HPMC 200000 include thickness and prevent drooping on vertical surfaces.

Droge

U lijekovima, HPMC 4000 i HPMC 6000 act as binders or film-coating agents for tablet computers. They manage just how fast a medication dissolves in the body. These grades are safe, netoksičan, and satisfy rigorous high quality requirements. Some high-viscosity variations also work as eye decrease thickeners to alleviate dryness.

Prehrambena industrija

Za hranu HPMC, uobičajeno HPMC 4000 ili HPMC 150000, functions as a thickener, stabilizator, ili emulgator. Održava sosove glatkim, stops ice crystals in frozen desserts, and boosts texture in gluten-free baked goods. It is approved for usage in lots of countries and identified as E464.

Boje i premazi

Paint makers make use of HPMC 80000 i HPMC 100000 to boost viscosity and stop pigment settling. These grades assist repaint spread equally and stick better to walls. They likewise decrease splatter during application and boost storage space security.

Razne druge upotrebe

HPMC appears in cosmetics, keramike, and agricultural chemicals too. U losionima, it gives a smooth feel. U keramičkim sjajima, it holds bits with each other prior to shooting. Low-viscosity grades like HPMC 400 match liquid systems, while ultra-high types like HPMC 200000 support gels or pastes. Each quality provides specific performance based upon its molecular weight and alternative level.

Frequently Asked Questions About HPMC Grades

What is HPMC and why are there so many numbers like 400, 4000, ili 100000?

HPMC stands for hydroxypropyl methyl cellulose. It is a common additive used in construction, hrana, i farmaceutski proizvodi. The numbers (400, 4000, 6000, itd.) show the viscosity of the product in millipascal-seconds (mPa·s). A low number like 400 means thin and fast-dissolving. A high number like 200000 means thick and slow-moving when mixed with water.

Which HPMC grade should I use for tile adhesives?

Za ljepila za pločice, medium to high viscosity grades work best. Choose HPMC 40000, 60000, ili 80000. These help keep the mix sticky and prevent tiles from sliding. They also improve water retention so cement can cure properly.

Can I use HPMC 400 in food products?

Da. HPMC 400 has very low viscosity and dissolves quickly in cold water. It is often used as a thickener or stabilizer in sauces, mliječne alternative, i peciva. Always confirm the product meets food-grade safety standards before use.

Why does my plaster crack when I use HPMC 150000?

HPMC 150000 is very thick. If you add too much, it can trap air or reduce workability. This may cause drying cracks. Use the right dosage—usually 0.2% to 0.4% of total dry weight—and mix thoroughly with other ingredients.

How do I store HPMC powder safely?

Držite HPMC na hladnom, suhom mjestu. Nakon otvaranja vrećicu dobro zatvorite. Moisture makes it clump or lose performance. Izbjegavajte direktnu sunčevu svjetlost i visoku vlažnost. Propisno uskladišteno, ostaje efikasan do 12 mjeseci.
