Main Characteristic Of Hydroxyethyl Methylcellulose

What is hydroxyethyl methylcellulose (HEMC)?

Hydroxyethyl methyl cellulose (HEMC) is also named as methyl hydroxyethyl cellulose (MHEC). It is a white, grayish-white, or yellowish-white granules.

It is a non-ionic cellulose ether derived from the addition of ethylene oxide to methylcellulose. It is produced from a natural renewable polymer such as wood pulp or cotton.HEMC can be used as a highly efficient water retention agent, adhesives and film-forming agent, stabilizer, etc.It is widely used in different industrial applications such as oil drilling, construction, and building, paint and coating, pharmaceutical, etc.HEMC can be modified according to customers’ requirement and still have its good anti-sagging property and good workability after modification.

However, for the best deal, working with a reliable modified methylcellulose supplier will guarantee of the best product for your money.

Like you may already know, the best products are those acquired from trustworthy and dependable manufactures.

So, in this article, we will discuss the properties that make gypsum plaster a better choice for plastering.

Adaptability Of Modified Methylcellulose In the Construction Industry

The high demands of gypsum-based plasters are a result of the harsh climate conditions and rigid construction and building standards in our environments.

Modified methylcellulose is an additive that improves the applications of gypsum-based coats, putties, epoxy resin, and spackling mixtures, cement, and tile adhesive, and related products.

Modified methylcellulose is used to optimize mortar quality to meet the challenging demands of the market.

It enhances the composite structures especially, its water resistance. This permits buyers to meet approved requirements, thereby improving the robustness and workability of commercial and domiciliary structures.

However, always purchase your modified methylcellulose from a reputable and reliable manufacturer for your best deal.

Application of HPMC in Building Materials

Hydroxypropyl Methylcellulose is a non-ionic cellulose ether made through a series of chemical processes, with the natural polymer cellulose as the raw material. It is odorless, tasteless and non-toxic white powder. In cold water, it swells into a clear or slightly turbid colloidal solution. Hydroxypropyl Methylcellulose and Methylcellulose can be used in building materials, coating industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemicals and other industries.

How to distinguish redispersible latex powder?

Redispersible latex powder is widely used in the construction industry as a kind of powder equipment binder. The quality of redispersible latex powder is immediately related to the quality and progress of engineering construction, along with China’s energy-saving construction With the rapid development trend of the sales market, there are more and more product R&D and manufacturing companies entering the redispersible natural latex powder products, and the space for customers to choose is also increasing.

But in addition, the quality of redispersible natural latex powder is becoming more and more uneven, with uneven quality. There is no shortage of some manufacturers in order to control costs, regardless of product quality standards, counterfeit or inferior products, or even counterfeit products, using general resin rubber powder to shout the banner of redispersible latex powder for cheap market sales, which not only disrupts the sales market Also deceived customers.

How to distinguish the quality of redispersible latex powder? Here are a number of basic ways to identify the quality of redispersible latex powder:

1. Distinguish from the appearance: Use a glass rod to cover a small amount of redispersible latex powder thinly and evenly on the neat glass surface, place the glass on tissue paper, and use visual effects to detect particles, foreign figures and condensation The appearance of things. The appearance of the redispersible latex powder should be milky white, freely flowing, well-proportioned powder without irritating taste. What is the quality problem? The main performance: the color of natural latex powder is abnormal; it contains residue; the particles are not smooth; there is a choking smell;

2. Dissolution method: Take a certain amount of redispersible latex powder and dissolve it in 5 times quality water, mix it enough, and let it stand for five minutes before observation. Under normal circumstances, the lower the non-substance that settles to the bottom layer, the better the quality of the redispersible latex powder;

3. Distinguish from the ash content: take a certain amount of redispersible latex powder, weigh it and place it in a stainless steel container, raise the temperature to 800℃, after 30 minutes of burning, refrigerate it to room temperature, and weigh it again. The quality of lighter weight is relatively good. Lightweight and cost-effective. The root cause of higher ash content is the high content of poor raw materials and inorganic compounds;

4. Use the demulsification method to distinguish: Demulsibility is the foundation for cement mortar to improve male sexual function. The poor demulsification ability is generally caused by excessively increasing the non-generator components or improper organic chemical components. The cost-effective redispersible latex powder has good demulsibility at room temperature, but it is not good at room temperature. Most of them have quality doubts about polymer or ash.

Test standard: Take a certain quality of redispersible latex powder, add water 1:1 and mix well, then let it stand for 2 minutes, then stir evenly, pour the aqueous solution on a piece of clean laminated glass, and place the laminated glass in a naturally ventilated shade. After enough dryness, tear off. Observe the polymer film that is torn off. High definition and high cost performance. Followed by appropriate involvement, good flexibility and high cost performance. Then cut the film into strips, soak it in water, and observe after 1 day, the less melted by water is cost-effective.

The above is only a simple way, can not distinguish the advantages and disadvantages, but can carry out the basic identification. Add the rubber powder to the cement mortar according to the instruction manual, and carry out the inspection of the cement mortar according to the matching cement mortar specifications. This kind of method is more objective.
