How to distinguish the quality of cellulose ether?from the ash content of HPMC

Shandong Huiguang?summarized?how to distinguish the quality of cellulose?from the ash content of HPMC?after combustion, and shared it with everyone,and hoping to be helpful to you.

1.?First of all, we must first understand what is ash:

Ash is also called burning residue, which can be simply understood as impurities in the product. It will be naturally generated during the production process. After the product comes out of the etherification reactor, it will enter the neutralization kettle. In the neutralization kettle, the pH value is first adjusted to be neutral, and then hot water is added for washing. The more hot water is added?and washing more times, the lower the ash content?in?HPMC, and vice versa.

2.?The size of the ash is also reflected in the purity of the HPMC. The higher the purity, the less ash after combustion.?

Next, let's analyze the information we get through the process of HPMC combustion.

The less ash, the higher the quality

Determining factors of the amount of ash residue:

(1)?Quality of cellulose raw material (refined cotton): In general, the better the quality of the refined cotton, the whiter the color, ash and water retention of the HPMC?produced.

All Shandong Huiguang’s?HPMC?raw materials are made from refined cotton, so quality is guaranteed.

(2) Number of washings: There will be some dust and impurities in the raw materials. The more washing times, the smaller the ash content of the finished product?of HPMC?after combustion.

(3) Adding small materials to the finished product will result in a large amount of ash after combustion.

(4) Failure to react well in the production process will also affect the ash content of HPMC.

(5) In order to confuse everyone's vision, some manufacturers will add combustion accelerants, and there is almost no ash after burning. In this case, everyone is required to remember the color and state of pure powder after burning, because the?HPMC?added with combustion accelerants can It is fully burned, but the color after burning is very different from that of pure powder.

3. Length of burning time: The burning time of HPMC?with good water retention rate will be relatively longer, and vice versa.

The lower the ash content in HPMC, the higher the quality,the less additive amount, which means the better the purifying?technology of this company. Therefore, this is an important reason for us to choose that manufacturer.

Shandong Huiguang Technology Development Co.,Ltd?is a one of the most professional cellulose ether manufacturer in China,?we are located in Binzhou City, Shandong Province.

Our company can produce 50000 tons every year for Hydroxypropyl Methyl Cellulose(HPMC), Hydroxyethyl Methyl Cellulose?(HEMC), Hydroxy Ethyl Cellulose (HEC), Methyl Cellulose (MC) etc. Our products can be widely used in?Plaster & Grouts, Adhesives, Paints & Coatings, Cement Extrusion, Oil Drilling, Personal Care, Food, Pharmaceutical?etc.
