Spray Polyurethane(喷涂聚氨酯)研究综述
Spray Polyurethane 喷涂聚氨酯 - Results for 81 urine samples collected from coating workers were compared with 28 urine samples of a reference group of 14 spray polyurethane foam (SPF) insulation workers. [1] In this paper a new test procedure is described that includes calculation methods to determine Temperature Dependent Long-Term Thermal Conductivity (LTTC(T)) functions for closed-cell foam insulation using as a test material, a Medium-Density Spray Polyurethane Foam (MDSPF). [2] The reduction in radon concentration in the mock house varied from 68% for 6 mil polyethylene to 98% for the spray polyurethane foam. [3] IECCU inputs included building environment (air zone configuration, airflow rates and temperature), source (spray polyurethane foam (SPF)) and sink (gypsum and wallboard) parameters, and simulation conditions. [4] In this study, we investigated chemical additives present in new and used spray polyurethane foams (SPFs) and assessed the dermal transfer through direct contact. [5] Small two-component spray polyurethane foam (SPF) application kits are often applied by Do-It-Yourself (DIY) consumers. [6] And, some of them were detected in the air at the plant manufacturing isocyanates and spray polyurethane foam. [7] Through the course, interdisciplinary teams of UC Berkeley students have worked with partner organizations to identify safer alternatives to chemicals of concern, including investigating safer preservatives in personal care products, nonfluorinated durable water-repellant coatings for outerwear, and safer cross-linkers to replace formaldehyde in permanent press textiles and diisocyanates in spray polyurethane foam insulation. [8] Huntsman has agreed to buy Icynene-Lapolla, a maker of spray polyurethane insulation foam, for $350 million. [9] In this work we characterize personal inhalation and dermal exposures to diphenyl methane diisocyanate (MDI) and other species in polymeric MDI (pMDI) formulations during spray polyurethane foam (SPF) insulation at 14 sites in New England. [10] Tris(1-chloro-2-propyl) phosphate (TCPP, also referenced as TCIPP), a flame retardant used in spray polyurethane foam insulation, increases cell toxicity and affects fetal development. [11] The industries were: carpet installation, chemical manufacturing, foam manufacturing, electronic scrap, gymnastics, rigid board installation, nail salons, roofing, and spray polyurethane foam. [12]将从涂装工人收集的 81 份尿液样本的结果与 14 名喷涂聚氨酯泡沫 (SPF) 绝缘工人的参考组的 28 份尿液样本进行比较。 [1] 本文描述了一种新的测试程序，其中包括计算方法来确定闭孔泡沫绝缘材料的温度相关长期热导率 (LTTC(T)) 函数，使用中密度喷涂聚氨酯泡沫 (MDSPF) 作为测试材料）。 [2] 模拟房中氡浓度的降低从 6 密尔聚乙烯的 68% 到喷涂聚氨酯泡沫的 98% 不等。 [3] IECCU 输入包括建筑环境（空气区配置、气流速率和温度）、源（喷涂聚氨酯泡沫 (SPF)）和水槽（石膏和墙板）参数以及模拟条件。 [4] 在这项研究中，我们调查了新的和使用过的喷涂聚氨酯泡沫 (SPF) 中存在的化学添加剂，并通过直接接触评估了皮肤转移。 [5] 小型双组分喷涂聚氨酯泡沫 (SPF) 应用套件通常由自己动手 (DIY) 消费者使用。 [6] 并且，在制造异氰酸酯和喷涂聚氨酯泡沫的工厂的空气中检测到其中一些。 [7] 通过该课程，加州大学伯克利分校学生的跨学科团队与合作伙伴组织合作，确定了更安全的化学品替代品，包括研究个人护理产品中更安全的防腐剂、外衣的非氟化耐用防水涂料以及替代甲醛的更安全的交联剂在永久压榨纺织品和喷涂聚氨酯泡沫绝缘材料中的二异氰酸酯。 [8] 亨斯迈已同意以 3.5 亿美元收购喷涂聚氨酯绝缘泡沫制造商 Icynene-Lapolla。 [9] 在这项工作中，我们描述了在新英格兰的 14 个地点在喷涂聚氨酯泡沫 (SPF) 绝缘期间个人吸入和皮肤暴露于二苯基甲烷二异氰酸酯 (MDI) 和聚合 MDI (pMDI) 配方中的其他物质。 [10] 三（1-氯-2-丙基）磷酸酯（TCPP，也称为 TCIPP）是一种用于喷涂聚氨酯泡沫绝缘材料的阻燃剂，会增加细胞毒性并影响胎儿发育。 [11] 这些行业包括：地毯安装、化学制造、泡沫制造、电子废料、体操、硬板安装、美甲沙龙、屋顶和喷涂聚氨酯泡沫。 [12]
