與目前制備生物降解顆粒方法相關的一個問題是表面活性劑和/或多溶劑的必要性,你知道包含什么事項嗎?下面小編為您介紹。
A problem related to the current methods of preparing biodegradable particles is the necessity of surfactants and/or polysolvents. Do you know what is included? Here is a brief introduction.
實際上,乳液法和溶液沉淀法都需要使用不止一種的溶劑和/或表面活性劑。而且在這些方法中可能使用的鹵化溶劑會造成健康問題并且影響環境。因此,不需要使用表面活性劑和/或包括鹵化溶劑在內的多種溶劑的制備生物降解顆粒的方法會是有益的,并且更節省成本。
In fact, both the lotion method and the solution precipitation method require the use of more than one solvent and/or surfactant. Moreover, halogenated solvents that may be used in these methods will cause health problems and affect the environment. Therefore, a method for preparing biodegradable particles without using surfactants and/or multiple solvents including halogenated solvents would be beneficial and more cost-effective.
主要涉及制備生物降解顆粒的方法,并且涉及在地下應用中使用這些生物降解顆粒的方法。
The invention mainly relates to a method for preparing biodegradable particles, and relates to a method for using these biodegradable particles in underground applications.
在一個實施方式中提供一種方法,其包括提供可降解聚合物和一種溶劑,其中溶劑包含選自以下組中的含水流體淡水、鹽水、鹵水、海水、及它們的組合;
In one embodiment, a method is provided, which includes providing a degradable polymer and a solvent, wherein the solvent comprises an aqueous fluid, fresh water, brine, sea water, and a combination thereof, selected from the following groups:;
生物降解顆粒
將可降解聚合物和溶劑組合形成可降解的聚合物組合物;使可降解聚合物少部分增塑;以及對可降解聚合物組合物施加足夠大的剪切,以使生物降解顆粒開始形成。
Combining a degradable polymer and a solvent to form a degradable polymer composition; Plasticizing the degradable polymer at least partially; And applying enough shear to the degradable polymer composition to start the formation of biodegradable particles.
