Hydroxypropyl Methylcellulose (HPMC), navê wê yê çînî hîdroksîpropil methylcellulose ye, nîv sentetîk e, Ethera selulozê ya ne-îyonîk ku bi kîmyewî guherandina seluloza xwezayî tê bidestxistin. Ev toza spî piştî ku di nav avê de hilweşe dikare çareseriyek vîskozek zelal çêbike. Stûrbûna wê ya hêja heye, ragirtina avê, aramî û taybetmendiyên çêkirina fîlimê. Ew di gelek warên wekî avahîsaziyê de pêvekek pirfunctional a domdar e, derman, û xwarinê.

Çareseriya avê ya hêja: Ew dikare zû di nav ava sar de were hilweşandin da ku çareseriyek zelal û aram çêbike.

Qalindbûna bi bandor û şiyana ragirtina avê: Vîskozîteya materyalê zêde bikin, bi bandor evaporasyona avê kêm dike, û karbidestiya xebatê baştir bikin.

aramiya baş: Li hember asîdan xwedan îstîqrara baş e, alkalis, û xwê, û ji bo cûrbecûr nirxên pH-ê maqûl e.

Fîlm-çêkirin û bandorên parastinê: Piştî hişkbûnê, ew fîlimek hişk û zelal çêdike da ku substratê biparêze û pêşî li derbasbûn û evaporkirina avê bigire.

Ne-jehrîn û ne-hêrs: Ew biyolojiya baş heye û ji bo warên derman û xwarinê minasib e.

Eyarkirin: Bi guherîna dereceya cîgir û giraniya molekulî, performansa wê dikare were guheztin da ku hewcedariyên serîlêdanê yên cihêreng bicîh bîne.

Hydroxypropyl Methyl Cellulose (HPMC)– Specs Babetê

Berhevkirinî

Hîdroksîpropyl methyl cellulose (HPMC) spî ber spî ye, odor-free powder. It liquifies quickly in cool water and develops a clear, option stûr. This product is widely utilized in building, derman, xûrek, and personal treatment due to its superb thickening, binding, and film-forming residential or commercial properties.

Notên vîskozîteyê

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

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

Kalîteyên Trick

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 û 90 ° C, depending upon the methoxyl and hydroxypropyl web content.

Cihê hilanînê û Handling

Store HPMC in an awesome, cîhek bi tevahî zuha dûr ji şilbûnê. 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.

Serîlêdanên Hydroxypropyl Methyl Cellulose (HPMC)

Avakirin û Materyalên Avakirinê

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

Drugs

Di dermankirinê de, HPMC 4000 û 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, ne jehrî, and satisfy rigorous high quality requirements. Some high-viscosity variations also work as eye decrease thickeners to alleviate dryness.

Pîşesaziya Xwarinê

Xwarin-pola HPMC, bi gelemperî HPMC 4000 an HPMC 150000, wekî stûrkerê kar dike, stabilizer, an emulsifiker. Ew sosê xweş diparêze, 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.

Paints and Coatings

Paint makers make use of HPMC 80000 û 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.

Various other Uses

HPMC appears in cosmetics, seramîkên, and agricultural chemicals too. Di lotikan de, it gives a smooth feel. Di şewqên seramîk de, it holds bits with each other prior to shooting.

Frequently Asked Questions About HPMC Grades

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

HPMC ji bo hîdroksîpropyl methyl cellulose ye. It is a common additive used in construction, xûrek, û derman. The numbers (400, 4000, 6000, etc.) 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?

Ji bo adhesives tile, medium to high viscosity grades work best. Choose HPMC 40000, 60000, an 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?

Erê. HPMC 400 has very low viscosity and dissolves quickly in cold water. It is often used as a thickener or stabilizer in sauces, alternatîfên şîr, û tiştên nanpêjkirî. 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. Heke hûn pir zêde zêde bikin, it can trap air or reduce workability. This may cause drying cracks. Use the right dosage—usually 0.2% ber 0.4% of total dry weight—and mix thoroughly with other ingredients.

How do I store HPMC powder safely?

HPMC-ê di sar de bihêlin, cîhê hişk. Piştî vekirinê çenteyê hişk bixin. Moisture makes it clump or lose performance. Ji tîrêja tavê ya rasterast û nemahiya zêde dûr bisekinin. Bi rêkûpêk hilanîn, ew heta bi bandor dimîne 12 mehan.
