Specifications of Hydroxypropyl Methyl Cellulose (HPMC)– Industrial Quality

Ko'rinish va jismoniy shakl

HPMC appears as a white to beige, erkin oqadigan kukun. It has no visible smell and liquifies easily in cool water to create a clear, qalin variant. The powder does not glob under regular storage space conditions.

Kimyoviy tarkibi

This industrial-grade HPMC is a semi-synthetic polymer originated from cellulose. It has methoxy (– OCH FOUR) and hydroxypropoxy (– OCH ₂ CHOHCH FOUR) functional groups. Common substitution levels are 19– 30% methoxy and 4– 12% hydroxypropoxy. These worths ensure consistent performance throughout different applications.

Qalinligi diapazoni

Viscosity varies based upon product grade. Common options consist of 400 mPa · s, 4,000 mPa · s, 15,000 mPa · s, va 60,000 mPa · s, all measured at 2% focus in water at 20 ° C. Greater thickness qualities supply more powerful thickening and film-forming residential properties.

Purity and Impurities

The product fulfills rigorous pureness criteria. Ash web content stays listed below 5%. Heavy steels like lead and arsenic are kept under 10 ppm. Residual moisture remains in between 4% va 8%, which assists keep security throughout storage space and handling.

pH and Solubility

A 2% liquid option generally reveals a pH between 6.0 va 8.0. HPMC dissolves easily in cold water but does not dissolve in warm water over 70 ° C or in a lot of natural solvents. This actions sustains its use in controlled-release and temperature-sensitive systems.

Mahsulotni qadoqlash va saqlash

HPMC is packed in multi-layer paper bags with an internal polyethylene liner. Har bir sumka ushlab turadi 20 kg yoki 25 kg. Ajoyib joyda saqlang, completely dry area away from straight sunshine and dampness. Keep containers sealed when not being used to avoid caking or loss of flowability. Proper storage ensures the item stays reliable for up to 24 oylar.

Applications of Hydroxypropyl Methyl Cellulose HPMC Industrial Grade

Gidroksipropil metil tsellyuloza qo'llanilishi (HPMC)– Industrial Grade

Qurilish va qurilish mahsulotlari

Industrial-grade HPMC plays a key function in building items. It is included in cement-based mortars, keramik plitka yopishtiruvchi moddalar, va o'z-o'zidan tekislanadigan moddalar. The substance boosts workability, suvni ushlab turish, va ochiq vaqt. This assists workers apply materials smoothly and uniformly. Better water retention also sustains appropriate concrete hydration, which leads to more powerful last frameworks.

Bo'yoqlar va qoplamalar

Suvga asoslangan bo'yoqlarda, HPMC functions as a thickener and stabilizer. It prevents pigments from settling and makes sure consistent structure throughout application. The additive also reduces splattering and enhances brush or roller circulation. These qualities help achieve uniform insurance coverage with less coats.

Adhesives and Sealants

HPMC improves the efficiency of industrial adhesives. It boosts thickness without impacting bond stamina. The product additionally regulates drying rate, giving customers more time to position components correctly. In sealers, it enhances communication and minimizes drooping on vertical surface areas.

Cleaning Agents and Cleansing Products

5 FAQs of Hydroxypropyl Methyl Cellulose HPMC Industrial Grade

Frequently Asked Questions About Industrial Grade HPMC

HPMC sanoat dasturlarida nima uchun ishlatiladi?

Gidroksipropil metil tsellyuloza (HPMC) suvda eruvchan polimer hisoblanadi. U qalinlashtiruvchi sifatida yaxshi ishlaydi, bog'lovchi, va film yaratuvchisi. Qurilishda, it helps improve workability and water retention in cement-based products like tile adhesives and renders. In paints and coatings, it controls viscosity and prevents sagging. It also stabilizes formulations in many other industrial processes.

Is industrial grade HPMC safe to handle?

Ha. Industrial grade HPMC is non-toxic and not classified as hazardous. It does not irritate skin or eyes under normal use. Hali ham, wear basic protective gear like gloves and safety glasses when handling large quantities. Avoid breathing fine dust during mixing. Uni quruq joyda saqlang, namlikdan uzoqroq joyda salqin.

How do I dissolve HPMC properly?

HPMC sovuq suvda eng yaxshi eriydi. Add it slowly while stirring to prevent clumping. You can also mix it with other dry powders first, then add water. Hot water causes it to gel too fast and form lumps. Let the mixture stand after mixing—it will fully hydrate in 15 uchun 60 daqiqa, depending on the grade.

Does HPMC work in high-temperature environments?

HPMC gels when heated. The exact temperature depends on the product type, usually between 50°C and 90°C. This property is useful in some applications but may limit use in very hot conditions. Choose the right grade based on your process temperature to avoid performance issues.
