Solvent Alternative - Hubbard-Hall-澳门威尼斯人网上赌场

可持续性和监管方面的担忧促使企业寻找传统溶剂(如n -丙基溴(NPB))的替代品。, Trichloroethylene (TCE), 以及用于金属部件清洗和脱脂的过氯乙烯(PCE/ PERC). 澳门威尼斯人网上赌场一直在帮助制造商解决这些问题，使用低影响的溶剂或水性清洁化学品.

Current Regulatory Status: April 2024

Trichloroethylene: In October 2023, 美国环保署提出了一项风险管理规则，以解决三氯乙烯对人类健康构成的不合理风险, 包括最终修订的TCE风险确定
Perchloroethylene: In June 2023, 环保署建议禁止PCE的大部分用途，并针对未被禁止的用途建立工作场所化学品保护计划(WCCP)，以解决对人类健康的不合理风险.
nPB: also known as 1-bromopropane (1-BP), In December 2022, EPA发布了最终修订的1-BP风险测定. The final revised risk determination finds that 1-BP, as a whole chemical, 在其使用条件下对健康有不合理的损害风险. Risk evaluation for 1-Bromopropane
Methylene ChlorideEPA最终确定了TSCA下的法规，以管理与二氯甲烷相关的风险. 这些规定包括禁止生产, processing, 为消费者提供二氯甲烷的分销. Additionally, most industrial and commercial uses, including paint and coating removers, are prohibited. 通过《澳门威尼斯人网上赌场》建立了严格的工作场所保护措施，以确保工人在剩余用途中的安全.
18 Months After Finalization (Estimated Late 2025)1:从2024年4月起，工作场所将有大约18个月的时间来遵守工作场所化学品保护计划. During this time, 他们必须实施严格的工作场所控制，并定期监测其环境，以确保工人不暴露于有害水平的二氯甲烷.
Future美国环保署计划举办网络研讨会，教育利益相关者了解最终的风险管理规则，并将制定指南，帮助小企业遵守法规. 将提供公众和利益相关者参与的机会, 包括与EPA代表进行一对一的会谈，以及获取电子邮件提醒和公共摘要以获取更新和信息.

Next-Gen Solvents

Solvent cleaning 蒸汽脱脂是使用有机溶剂溶解部件上的有机污染物的过程.

More environmentally friendly solvents such as modified alcohols (Dowclene™和Dualene™)可用于真空脱脂剂中，以节省成本，安全性和有效性. 这种溶剂清洗需要资金投入, including the purchase of a vacuum degreaser.

Tergo is a precision cleaning fluid that is a non-flammable, 热和水解稳定的清洁剂，可以滴入一个开顶蒸汽脱脂剂与最小的变化或改造.

Aqueous Cleaners

Aqueous cleaning 是使用化学添加剂的水基工艺吗, surfactants and rinsing to remove contaminants.

我们为任何土壤、基质或清洁过程提供70多种水基化学品. With a transition to aqueous cleaning, 您应该考虑这将如何影响您的过程中使用的热量, multiple tanks, drying time and increased footprint.

Cleaning is a Process

虽然氯化/氟化/溴化溶剂在精密清洗方面具有优势, 还有其他方法可以清除金属表面的土壤. 清洁被认为是一个过程，因为它不仅仅是化学的——好的清洁取决于几个因素:

Metal type
Soil type
Parts geometry
Available footprint
Application cleanliness requirements

Throughput requirements
Energy demands
EHS and regulatory
Waste handling
Cost

Why Switch to an Alternative?

On December 20, 2019, 根据《澳门威尼斯人网上赌场》(TSCA)， EPA最终确定了20种化学物质为“风险评估高优先级”。. Included are Methylene chloride, Perchloroethylene (PCE/ PERC), 正丙基溴(NPB)——EPA称之为1-溴丙烷——和三氯乙烯(TCE).

Today, 这些化学品正在通过《澳门威尼斯人网上赌场》要求的程序，以评估它们可能对人类健康或环境构成的任何不合理风险. 下一步是按优先顺序对这些现有化学品进行风险管理. 环保署可以采取一些措施来解决不合理的风险, 包括禁止或限制生产的规定, processing, distribution, commercial use, or disposal of the chemical substance, as applicable.

Solvent Risk Mitigation by Regulatory Bodies

此外，不同的监管机构对降低风险有不同的看法. Below is an example on how OSHA, ACGIH和EPA对TCE/PEC/nPB/MEC的可接受暴露限值有所不同.

Solvent	OSHA (PEL) ppm	ACGIH (TLV) ppm	EPA (ECEL) ppm
TCE	100	25	0.004
PCE	100	25	0.14
NPB	n/a	0.1	0.05
MEC	25/125*	50	2/16*
Legend: Ppm – parts per million Tlv – threshold limit value Pel – permissible expose limit Ecel – existing chemical exposure limit (8 hour) Stel – short term exposure limit (15 minutes)
