Abstract
(EN) Disclosed is a starch-containing microsphere and a preparation method therefor and an application thereof. The particle size of the starch-containing microsphere exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval, and the particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is (I), where n is an integer greater than 1. The preparation method comprises: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres prepared by the present invention are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 μm.
(FR) L'invention concerne une microsphère contenant de l'amidon, un procédé de préparation s'y rapportant et une application de celle-ci. La taille de particule de la microsphère contenant de l'amidon présente une polydispersité avec une distribution uniforme sur un étroit intervalle de distribution de la taille de particule et la distribution de la taille de particule dans l'étroit intervalle de distribution de la taille de particule a les caractéristiques suivantes : une division égale de l'étroit intervalle de distribution de la taille de particule en n intervalles et un pourcentage de microsphères dans chaque intervalle de (I), n étant un nombre entier supérieur à 1. Le procédé de préparation comprend : d'abord la réaction d'amidon avec une faible concentration d'épichlorhydrine, puis la réaction du produit ainsi obtenu avec un tensioactif, suivie d'une réticulation finale pour donner des microsphères. Les microsphères contenant de l'amidon préparées par la présente invention sont des microsphères contenant de l'amidon polydispersées ayant une distribution uniforme de la taille des particules, la taille des particules étant dans une plage de 0,1 à 500 µm.
(ZH) 公开了一种含淀粉微球及其制备方法和应用，所述含淀粉微球粒径在粒径集中分布区间内呈均匀分布的多分散性，所述粒径集中分布区间内的粒径分布具有如下特征：将粒径集中分布区间均分成n个区间，每个区间的微球占比为：(I) 其中n为大于1的整数。所述制备方法为，首先将淀粉与低浓度环氧氯丙烷反应，然后与表面活性剂作用，最后再进行交联得到微球。本发明制备的含淀粉微球是粒径均匀分布的多分散含淀粉微球，粒径为0.1～500μm。
