羟丙基甲基纤维素的应用介绍  

  羟丙基甲基纤维素,也称为羟丙基甲基纤维素和纤维素羟丙基甲基醚,由高纯度的棉纤维素制成,并在碱性条件下特别醚化。下面是羟丙基甲基纤维素厂家针对羟丙基甲基纤维素的应用介绍。

  主要应用领域:

  1、建筑业:作为水泥砂浆的保水剂和混凝剂,可以泵送砂浆。使用砂浆,石膏,腻子粉或其他建筑材料作为粘合剂,以提高适用性并延长操作时间。用作粘贴瓷砖,大理石,塑料装饰,粘贴增强剂,还可以减少水泥用量。HPMC的保水性能使得浆料在涂覆后避免因干燥过快而开裂,提高硬化后的强度。

  2、陶瓷制造:广泛用作陶瓷制品的粘合剂。

  3、涂料工业:作为涂料工业中的增稠剂,分散剂和稳定剂,在水或有机溶剂中具有良好的溶解性。作为脱漆剂。

  4、油墨印刷:作为油墨工业中的增稠剂,分散剂和稳定剂,在水或有机溶剂中具有良好的溶解性。

  5、塑料:可用作脱模剂,柔软剂和成型润滑剂。

  6、聚氯乙烯:作为聚氯乙烯生产中的分散剂,是悬浮聚合制备PVC的主要助剂。

  7、其他:该产品还广泛用于皮革,纸制品,果蔬保鲜和纺织工业。

  8、医疗行业:涂层材料;膜材料;用于缓释制剂的受控速度聚合物材料;稳定剂;暂停援助;片剂粘合剂;增加粘性

  建筑领域应用:

  1,水泥砂浆:提高水泥砂的分散性,大大提高砂浆的可塑性和保水性,对防裂有效,可提高水泥的强度。

  2、瓷砖水泥:提高瓷砖砂浆的可塑性,保水性和附着力,防止粉末。

  3、石棉和其他耐火材料的涂层:作为悬浮稳定剂,迁移率改进剂和粘合剂继电器到底座。

  4、石膏凝结剂:改善保水性和加工性,并改善对基材的附着力。

  5、接缝水泥:将其加入石膏板中使用的接缝水泥中,以改善流动性和保水性。

  6、乳胶腻子:改善树脂乳胶基腻子的流动性和保水性。

  7、砂浆:作为替代天然材料的糊状物,它可以改善保水性并改善相同基底的附着力。

  8、涂料:作为乳胶涂料的增塑剂,可以改善涂料和腻子粉的操作性能和流动性。

  9、喷漆:为了防止水泥系统或乳胶系统被喷涂,只有材料填料会下沉并改善流动性。

Hydroxypropyl methyl cellulose, also known as hydroxypropyl methyl cellulose and cellulose hydroxypropyl methyl ether, is made from highly pure cotton cellulose and specially etherified under alkaline conditions.
The main purpose
1. Construction industry: as the water retention agent and coagulant of cement mortar, the mortar can be pumped. Apply mortar, gypsum, putty powder or other building materials as adhesive to improve the applicability and prolong the operating time. Use as stickup ceramic tile, marble, plastic adornment, stickup strengthen agent, still can reduce cement dosage. The water retention property of HPMC enables the paste to avoid cracking after application due to too fast drying, enhancing the strength after hardening.
2. Ceramic manufacturing: widely used as adhesive in ceramic product manufacturing.
3. Coating industry: as thickener, dispersant and stabilizer in the coating industry, it has good solubility in water or organic solvents. As a paint remover.
4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good solubility in water or organic solvents.
5. Plastic: it can be used as mold release agent, softener and lubricant for forming.
6. Polyvinyl chloride: as dispersant in the production of polyvinyl chloride, it is the main auxiliary agent for the preparation of PVC by suspension polymerization.
7. Others: this product is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
8. Medical industry: coating materials; Membrane material; Controlled speed polymer materials for slow-release preparations; Stabilizing agent; Suspended aid; Tablet adhesive; Increases the goo
Architectural folding
1. Cement mortar: improve the dispersibility of cement-sand, greatly improve the plasticity and water retention of mortar, which has an effect on crack prevention and can enhance the strength of cement.
2. Ceramic tile cement: improve the plasticity, water retention and adhesion of ceramic tile mortar to prevent powder.
3. Coating of asbestos and other refractories: as suspension stabilizer, mobility improver, and adhesive relay to base.
4. Gypsum coagulant: improve water retention and processing, and improve adhesion to the base.
5. Joint cement: it is added to the joint cement used in gypsum board to improve the fluidity and water retention.
6. Latex putty: improve the fluidity and water retention of resin latex based putty.
7. Mortar: as a paste to replace natural materials, it can improve water retention and improve the adhesion of the same base.
8. Coating: as a plasticizer for latex coating, it can improve the operation performance and fluidity of coating and putty powder.
9. Spray paint: to prevent the cement system or latex system from being sprayed, only the material filler will sink and improve the fluidity
