與目前制備生物降解顆粒方法相關(guān)的一個(gè)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(xiàng)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(shí)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(huì)造成健康問題并且影響環(huán)境。因此，不需要使用表面活性劑和/或包括鹵化溶劑在內(nèi)的多種溶劑的制備生物降解顆粒的方法會(huì)是有益的，并且更節(jié)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(yīng)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(gè)實(shí)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:;

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(duì)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.

在另一個(gè)實(shí)施方式中提供一種方法，其包括提供可降解聚合物和基本由含水流體組成的溶劑，其中含水流體選自以下組中淡水、鹽水、鹵水、海水、及它們的組合；

In another embodiment, a method is provided, which includes providing a degradable polymer and a solvent basically composed of an aqueous fluid, wherein the aqueous fluid is selected from fresh water, brine, brine, sea water, and their combinations in the following groups:;

將可降解聚合物和溶劑組合形成可降解聚合物組合物；使可降解聚合物少部分增塑；對(duì)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；以及將少部分的生物降解顆粒加入處理液中。

Combining a degradable polymer and a solvent to form a degradable polymer composition; Plasticizing the degradable polymer at least partially; Apply enough shear to the degradable polymer composition to start the formation of biodegradable particles; And adding at least part of the biodegradable particles into the treatment solution.
