सेलूलोज़ ईथर एचपीएमसी का उपयोग और विशेषताएँ
The production process of MHEC powder involves several sequential stages. It commences with the extraction of cellulose from natural sources like wood pulp or cotton. Subsequently, the extracted cellulose undergoes alkalization. The ensuing step encompasses etherification via sodium mono chloroacetate, culminating in the production of MHEC. This resultant substance is then subjected to purification, drying, and milling, ultimately yielding the final MHEC product.
Concrete mixes using Methylcellulose are commonly used for their smoothness and strength. Methylcellulose is used to coat the interior surface of concrete pipes, giving them a uniform thickness that reduces wear over time. This method also produces lines resistant to cracking when exposed to water, heat, or other harsh conditions.
