The water retention property of mortar refers to the ability of mortar to retain water. Mortar with poor water retention property is easy to bleed and segregate

The higher the clarity of hydroxypropyl methyl cellulose, the better the water solubility. The factors that affect the water solubility of wet cement mortar

The working mechanism of methyl hydroxyethyl cellulose, MHEC (Mw = 2.5 · 105 g/mol, DSmethyl = 1.81, MShydroxyethyl = 0.15) as water retention agent in cement was investigated. First, the hydrocolloid was characterized and its performance as non-ionic water retention agent was determined employing the filter paper test. Also, water sorption and swelling of individual MHEC fibers under conditions of different humidities were monitored by ESEM imaging. Second, its working mechanism was established. It was found that at low dosages, MHEC achieves water retention by intramolecular sorption of water and concomitant swelling while at higher dosages, MHEC molecules agglomerate into large hydrocolloidal microgel particles (d > 1 μm) which effectively plug the pores in the mortar matrix. MHEC association was evidenced by an exponential increase in solution viscosity as concentration rises, a strong increase in the hydrodynamic diameter of solved MHEC molecules, and a noticeable reduction of surface tension.

Polyvinyl alcohol (PVA) is a synthetic polymer noted for its water solubility. It’s derived from the chemical breakdown of polyvinyl acetate through water, or a process called hydrolysis. Due to being water-soluble, it’s considered an environment-friendly compound, useful across various industries. Polyvinyl alcohol is present in most consumer goods today. It’s a valuable compound used by different industries to enhance their products’ quality, function, and efficacy. These significant improvements revolutionise production and consumption.  That said, here are six industrial applications of polyvinyl alcohol.  

Because PVA has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, abrasion resistance and water resistance after special treatment, in addition to being used as a fiber raw material, It is also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products, which are used in textiles, food, medicine, construction, wood processing, paper, printing, agriculture, polymer chemical industry and other industries.

PVA (Polyvinyl Alcohol) is a synthetic plastic polymer found in many of our everyday products. PVA is often found in household items like dishwasher and laundry pods and sheets as a thin single-use plastic wrapping or woven into laundry sheets themselves. In the U.S. alone, research shows over 20 billion PVA wrapped dishwasher and laundry pods are used every year. While the plastic wrapping around these pods might seem innocuous, when it comes to PVA, there is more than meets the eye. A recent study published in the International Journal of Environmental Research and Public Health titled: Degradation of Polyvinyl Alcohol in US Wastewater Treatment Plants and Subsequent Nationwide Emission Estimate, shows that while PVA does dissolve, it doesn’t always biodegrade. We’re breaking down the naked truth about laundry and dishwasher pods, and unpacking the real implications of PVA.

PVA, short for polyvinyl alcohol, is a colorless, odorless synthetic polymer that is soluble in water. As a synthetic polymer, PVA is classified as a plastic made from fossil fuel sources. It is sometimes abbreviated to PVOH or PVAl to differentiate it from a similarly named compound, polyvinyl acetate which is most commonly used in wood glues. 

Polyvinyl Alcohol (PVA, sometimes referred to as PVOH) is a water soluble polymer used widely in adhesives, paints, sealants, coatings, textiles, plastics, etc. The polymer is normally supplied in powder form and several grades are available with varying viscosity and solubility characteristics. 

I see it mentioned frequently—and hotly debated—online, and among the cleaning product industry, many environmental communities, and some scientists. The issue revolves around whether the ingredient is plastic or not, and further, whether its existence in products that are going to travel down the drain into our water waste system is a problem.

Polyvinyl Alcohol (PVA) is a versatile synthetic polymer that has found its way into a myriad of industrial applications due to its unique properties. This article aims to provide an objective overview of PVA, exploring its uses, properties, and the environmental implications of its widespread use.

Polyvinyl Alcohol (PVA) is a biodegradable and water-soluble synthetic polymer used in a wide variety of different products and processes.Other acronyms that are commonly used to refer to polyvinyl alcohol include PVOH and PVAI.

Polyvinyl Alcohol (PVA), also known as also known as PVOH, PVA, or PVAL, is a man-made or synthetic polymer made from the polymerization of vinyl acetate monomer. PVA polymer molecule contains vinyl and alcohol groups. It is a water-soluble polymer that is odorless, non-toxic, crystalline, bio-degradable,environment-friendly, and flammable in nature, and is resistant to grease, oils, and solvents.

It’s a chemistry wonder! Polyvinyl Alcohol (PVA, PVOH or PVAI) is a synthetic polymer. This means it’s made up of many molecules strung together like a necklace. PVA starts as ethylene. Then, oxygen and acetic acid (or vinegar when it’s diluted) turn the ethylene into vinyl acetate — which is then dissolved into alcohol to become Polyvinyl Alcohol.
