Application of hydroxyethyl cellulose
Hydroxyethyl cellulose can be called HEC for short. It is a kind of non-ionic cellulose ether, obtained from natural polymer cellulose through a series of chemical processing. It is a odorless, tasteless, non-toxic white powder or particles. Mainly used

Description

The form of hydroxyethyl cellulose is a odorless, tasteless, non-toxic white powder or particles, can be dissolved in cold water, forming a transparent viscous solution, not affected by PH. It has a viscosity of 30000-100000, particle size of 0.18 mm, PH value of 6.0-8.0, hydroxyethyl cellulose can pass through 100 mesh at 98% . It has thickening, binding, dispersing, emulsifying, film forming, suspension, adsorption, surface activity, moisture

retention, salt resistance and other properties.


Hydroxyethyl cellulose is packed in paper-plastic bags or cardboard drums lined with polyethylene bags, each bag weighs about 25 kg. This kind of packing can not only effectively protect hydroxyethyl cellulose from outside influence, it is also easy to use and store. Store in a sealed, dry, ventilated place. Dry environment can prevent moisture caking, maintain good performance. And in the storage and transport process to prevent the sun and rain and pay attention to moisture, to ensure that hydroxyethyl cellulose in the transport process always in an ideal state.


For the application of water-based latex paint, HEC as protective colloid can be used in vinyl acetate emulsion polymerization to improve the stability of the polymerization system in the PH range to ensure the successful polymerization. In the treatment of pigments and fillers, HEC can make additives uniformly dispersed, stable and provide thickening effect in finished product manufacture. It is also used as a dispersant to suspend polymers such as styrene, acrylate and propylene. Used in latex paint, can significantly improve thickening and leveling performance.


In the field of architecture and building materials, hydroxyethyl cellulose is an indispensable role. HEC is an effective thickener and binder for cement mortar and mortar, which can improve the fluidity and construction performance, make the construction more convenient and efficient, and prolong the evaporation time of water, improve the initial strength of concrete, avoid cracks, to ensure the quality of construction. It can also be used for plaster, bonding plaster and plaster putty, and can significantly improve its water retention and bonding strength. Water-retaining emulsifying ability, not easy to dry, long-term maintenance of material performance stability.

Hydroxyethyl cellulose also plays an important role in oil drilling。In the process of oil extraction, mud treatment is a very important key process. Because hydroxyethyl cellulose has the properties of thickening, suspension and lubrication, it can be used in drilling mud to improve the filtration performance and the stability of the mud. At the same time, in the drilling and large drilling technology, the application effect is also very good, can reduce the friction of the mud, thus can reduce pump pressure, reduce power consumption. In cementing and cementing process, hydroxyethyl cellulose can reduce pump pressure, increase rate, and more importantly, it has excellent water loss, can effectively prevent water from flowing to the rock. Thus, not only plays an important role in the construction, the oil industry is also indispensable presence.

Hydroxyethyl cellulose, with its unique and outstanding characteristics, has become an ideal choice in many fields.First, it has a high thickening effect and can easily achieve the desired consistency in a variety of applications, providing just the right texture and stability for the product.Secondly, hydroxyethyl cellulose has excellent rheological properties. This means that he can flexibly adjust the flow characteristics of materials according to different process and application requirements.Furthermore, it is also very good dispersion and solubility, can quickly and evenly dispersed in the system, completely dissolved.Finally, the stability of storage is also a major feature, after a long period of storage, but also to maintain its excellent performance.
