产品性质

PRODUCT PROPERTY

1,无臭、无味

天禾®美乐仕®纤维素醚产品是一种纤维状或颗粒状粉末,颜色是白色至类白色,并且无臭、无味。

2,天禾®美乐仕®纤维素醚灰分含量低

美乐仕®纤维素醚产品是一种非离子型有机化合物,在合适的条件下,它可以完全燃尽。在生产过程中,用热水将其有效的洗涤,所以它的灰分含量非常低。

3,冷水中的溶解性和增稠能力

虽然天禾®美乐仕®纤维素醚产品在热水中不溶解,但是它可以溶解在冷水中,形成透明的粘稠溶液。

4,热凝胶

当美乐仕®纤维素醚产品的水溶液加热到一定温度时,将产生沉淀或凝胶,但是在随后的冷却中,它返回原来的溶液状态。产生凝胶或沉淀的温度,依赖于美乐仕®纤维素醚产品的型号、浓度以及加热的速度。 

5,抗盐析

天禾®美乐仕®纤维素醚产品属非离子型高分子有机物,而不是聚电解质。甚至在金属盐或有机电解质存在下,美乐仕®纤维素醚产品的水溶液也相当稳定。然而,当电解质的浓度超过一定极限时,可以产生沉淀和凝胶。

6,pH稳定性

天禾®美乐仕®纤维素醚产品水溶液的粘度很难被酸或碱影响,在pH3.0—11.0范围内,美乐仕®纤维素醚产品能够保持原有的粘度。但是,在酸性或碱性条件下延长储存时间,溶液粘度趋于下降。

7,在有机溶剂中的溶解性

因为天禾®美乐仕®纤维素醚产品具有比较亲油的甲氧 基、羟乙氧基或羟丙氧基,所以它可以溶解在有机溶剂中,也可以溶解在水—有机溶剂的混合溶剂中。

8,表面活性

天禾®美乐仕®纤维素醚产品的水溶液具有高的表面活性,可以用作保护胶体助剂、乳液稳定剂、泡沫稳定剂和分散剂。

9,成膜性

美乐仕®纤维素醚产品的水溶液可以形成牢固的、柔韧的、透明的膜,这种膜对油和油脂具有好的防护性能。

10,保水性

因为天禾®美乐仕®纤维素醚产品是亲水性的,并且它的水溶液非常粘稠,所以美乐仕®纤维素醚产品加入砂浆等,可以为这些产品提供高的保水性。

11,形状保持性

因为高浓度的美乐仕®纤维素醚产品水溶液与其它水溶性聚合物相比,显示较高的粘度和粘弹性,所以它可以增强挤出陶瓷和水泥产品的形状保持性。

12,润滑性

在挤出过程中,加入美乐仕®纤维素醚产品可以降低摩擦系数,提高润滑性。

Products Property

·          

1,Odorless and Tasteless

MEILESI® products are a kind of fibrous or granular powder. They are white to off-white, odorless and tasteless.

2,Low Ash Content

MEILESI® products are a kind of nonionic organic compound. Under right conditions, they can be completely burnt out. In the process of production, they are effectively washed with hot water, so their ash content is very low.

3,Solubility and Thickening Ability in Cold Water

MEILESI® products do not dissolve in hot water, but they dissolve in cold water and forms a transparent viscous solution.

4,Heat Gelation

When the water solution of MEILESI® Products is heated to a certain temperature, sediments or gels will generate, but in the later process of cooling, the water solution will return back to its original solution state. The temperature which leads to gels or sediments depends on the type and concentration of MEILESI® products and heating rate.

5,Salting-out Resistance

MEILESI® products are nonionic instead of polyelectrolyte. Even under the condition that metal salt or a organic electrolyte exists, the water solution of MEILESI products is rather stable, but when the content of electrolytes exceed a certain limit, sediments or gels will generate.

6,pH Stability

The water solution viscosity of Pan-Key Products is very difficult to be affected by acid or alkali.Within the range of pH3.0-11.0, Pan-Key products can keep their original viscosity.But if the storage time is extended under the acid or alkali condition, the solution viscosity tends to decline.

7,Solubility in Organic Solvent

Because Pan-Key products carry with methoxy groups and hydroxypropoxy groups which are oleophilic, they can dissolve in organic solvents and also they can dissolve in mixed solvents of water and organic solvents.

8,Surfactivity

The water solutions ofMEILESI® products have high surfactivity, so they can be used as protective colloid additives,emulsion stabilizer,foam stabilizer and dispersing agent.

9,Film-Forming Property

MEILESI® products can form a strong, flexible and transparent film which has a good protective property for oil and grease.

10,Water Retention

Because MEILESI® products are hydrophilic and their water solutions are very thick, they can provide mortars with high water retention.

11,Shape Retention

Compared with other water soluble polymers, the water solutions of MEILESI® products in high concentration has higher viscosity and viscoelasticity, so Pan-Key products can enhance the shape retention of extruded ceramics and cement products.

12,Lubricating Property

In the extrusion process, adding MEILESI® product can reduce the friction coefficient and improve the lubricating property.
