发泡剂

Associated with production practice and sweetening technology's analysis, certain solution pollution sources are corrosion inhibitor and surface acting agent and ferried from corruption and hydrate inhibiter reaction by product.

利用红外光谱仪分别对纯净脱硫溶液和发泡脱硫溶液进行分析、比较，确定出发泡溶液中的杂峰，根据这些杂峰找出其对应的基团；然后结合对开采工艺和脱硫工艺所使用的化学剂研究，确定脱硫溶液中的有机杂质主要有：缓蚀剂、表面活性剂、水合物抑制剂和脱硫溶剂的反应副产物。

Biurea particles with different diameters and a mixture of biurea and blowing agent ADC with different wettability were used in the experiments.

实验用的固体混合物物料一组为粒径不同的联二脲颗粒，另一组为润湿性不同的联二脲与发泡剂ADC颗粒的混合物。

The oxidation of solid biurea with chlorine in aqueous solution to produce azodicarbonamide was experimentally studied in a 1 L agitated glass vessel with a four-blade paddle stirrer. Based on the film theory, a model is first developed for this system by taking the gas-liquid and solid-liquid mass transfer, solid dissolution, and instantaneous reaction between the dissolved reactants into consideration.

在玻璃搅拌反应器中进行了固体联二脲与氯气液相氧化反应生成发泡剂 ADC过程的传质与动力学实验，提出了基于双膜理论的数学模型，以描述这一反应系统所涉及的气液和固液传质、固体溶解以及溶解物在液相中发生瞬间反应，特别是随反应进行固体反应物粒径变小导致固液传质速率减小的复杂过程。

济南华尔沃进出口贸易有限公司是一家集研发、生产、贸易、服务于一体的外贸型经济实体，以专业经营化工原料为主，公司现有生产AC发泡剂、三氯化铁、水合肼、对硝基苯酚、间苯二胺、三氯化磷、三氯氧磷、2，4—二氨基苯磺酸钠、二氯异氰脲酸钠、N-甲基邻苯二胺二盐酸盐等精细化工产品的能力，并且均以取得ISO9001国际质量体系认证。

A conclusion can be educed that compounded experiment is a effective way to improve properties of the foaming agent.

可见，通过复配提高发泡剂的性能是一条有效途径。

In order to accomplish this change, our research have made several important break-through by revising new formulation especially in (1) catalyst mix,(2) adjustment of water content,(3) addition of chain extenders and crosslinkers, and(4) utilization of long-chained polyols. By doing so, the general performances of our new non-yellowing foam products are comparable to those of the traditional TDI based products. In certain mechanical properties in areas such as tensile strength, split tear strength, and elongation our measured values of 1.89 kg/cm2, 1.47 kg/cm, and 355 % respectively have out-performed the old materials.

能在研究中突破的原因，是因针对聚胺酯发泡体配方中的催化剂、水含量、链长剂种类、交联剂及搭配商业之改质长链三元醇，做各式各样之配方调整而成，与传统商业用之芳香族发泡体相比较，基本的成泡指数及性质相比拟上已相近，在抗张(1.89 kg/cm2，比TDI系统增加2.2倍)、撕裂(1.47 kg/cm，比TDI系统增加1.7倍)、延伸率(355 %，比TDI系统增加1.6倍)等机械性质上甚至比芳香族发泡体有更佳的表现。

The refrigerants that are used in the foaming agents that help to insulate and those in the circuit used in refrigerating should only have an ozone depleting potential of zero.

在中所使用的发泡剂帮助隔离和在制冷只能用具有零消耗臭氧潜能电路的制冷剂。

Molina and Rowland have proved that chlorine is the cause of damages to the ozone layer: When man-made fluorocarbons are used in products (including aerosol cans, refrigerants, or blowing agent for foam plastics), they will be released to the atmosphere.

马利纳和罗蓝得证实氯为破坏臭氧层的元凶：人造的氟氯碳化物会在产品（包括喷雾罐、冷气机冷媒或泡绵的发泡剂等）使用时，被排放至大气中。

My company's main products are R11, R12, R13, R22, R227, R502, R141b, R142b, R152a, R113, R134a, R402A (HP80), R402B (HP81), R404A (HP62), R123, R407C, R410A, R507 , Tsinghua series refrigerants, as well as some related products such as dichloromethane, chloroform, halons, refrigeration oil and blowing agent (R11, R245) and so on.

我公司的主要产品有 R11 、 R12 、 R13 、 R22 、 R227 、 R502 、 R141b 、 R142b 、 R152a 、 R113 、 R134a 、 R402A （ HP80 ）、 R402B （ HP81 ）、 R404A （ HP62 ）、 R123 、 R407C 、 R410A 、 R507 、清华系列制冷剂，以及一些相关产品如二氯甲烷、三氯甲烷、聚四氟乙烯、冷冻油及发泡剂（ R11 、 R245 ）等。

However, Steven van Hoeck, v.p. of sales at Alliance Gas Systems, believes the rough inner surface could be due to too much pressure on the gas or leaving the gas in the part too long—both causes for the gas to begin to act as a foaming agent.

然而，Alliance Gas Systems公司的副总裁Steven van Hoeck却认为内表面的粗糙是归因于气压太高或气体停留在制品内太久，因为这两个因素都使气体起到发泡剂的作用。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
