  • 相变微胶囊定义

    Definition of phase change microcapsules


    微胶囊技术是一种运用成膜材料将固体或液体包覆成具有核壳结构微粒的技术,所得微粒称为微胶囊。

    Microcapsule technology is a technology that uses film-forming materials to coat solids or liquids into particles with a core-shell structure. The resulting particles are called microcapsules.


    微胶囊的制备技术起源于20实际50年代,在70年代中期得到迅猛的发展,在此时期出现了微胶囊化产品和工艺。如:药物、酶、香水、催化剂、染料等产品都应用了微胶囊化的封装形式。

    The preparation technology of microcapsules originated in the 1950s and developed rapidly in the mid-1970s. During this period, microencapsulated products and processes appeared. Such as: drugs, enzymes, perfumes, catalysts, dyes and other products are all applied in the form of microencapsulation.


    由于相变材料在使用过程中,是通过自身固液转换来吸收或释放热量。故在应用到纺织品或者电子产品等地方时,变成液体的相变材料容易流失。所以,采用微胶囊技术,将相变材料包裹起来,使其可应用于纺织品等应用领域。

    Because the phase change material absorbs or releases heat through its own solid-liquid conversion during use. Therefore, when applied to textiles or electronic products, the phase change material that becomes liquid is easy to lose. Therefore, the use of microcapsule technology to wrap the phase change material so that it can be used in applications such as textiles.


    相变微胶囊借鉴了这一技术,将相变材料分散成球形小颗粒,然后在表面封装一层性能稳定的壳材,最终形成相变微胶囊。将相变材料微胶囊化这一技术很好的解决了其应用中的问题与难点(液体材料流失,腐蚀性,体积变化率等)。相变微胶囊的芯材-相变材料在吸热时成液态,但外壳仍为固体,因此材料的外形仍为固态颗粒。

    Phase change microcapsules learn from this technology, disperse the phase change material into small spherical particles, and then encapsulate a layer of stable shell material on the surface to form phase change microcapsules. The technology of microencapsulation of phase change materials solves the problems and difficulties in its application (liquid material loss, corrosivity, volume change rate, etc.). The core material of the phase change microcapsule-the phase change material becomes a liquid when it absorbs heat, but the outer shell is still solid, so the shape of the material is still solid particles.

    具体的相变微胶囊的参数(密度、焓值、热传导系数等)根据不同温度的相变微胶囊是不一样的。且,在不同的应用领域中,相变微胶囊的使用温度点也是不同的。具体以实际需求为准。

    The specific parameters of phase change microcapsules (density, enthalpy, thermal conductivity, etc.) are different according to phase change microcapsules at different temperatures. Moreover, in different application fields, the use temperature points of phase change microcapsules are also different. Specifics are subject to actual needs.
