用于聚氨酯生产的异氰酸酯的生产 异氰酸酯和聚氨酯生产中的聚合控制 聚氨酯 (PU) 可用于制造许多不同的物品,例如油漆、液体涂料、合成橡胶、绝缘体、弹性体、泡沫和整体蒙皮。 聚氨酯由二异氰酸酯与多元醇聚合而成。 用于生产聚氨酯 (PU)的最常用异氰酸酯是亚甲基二苯基二异氰酸酯 (MDI) 和甲苯二异氰酸酯 (TDI)。如果注重颜色和透明度,可使用脂肪族二异氰酸酯,如六亚甲基二异氰酸酯 (HDI)。 维萨拉 K-PATENTS® 在线折光仪可针对异氰酸酯和聚氨酯 (PU)生产中的不同应用提供准确可靠的折射率测量。 例如,原位在线折光仪可连续监测聚合反应进度。这有助于确定反应的程度和终点。 利用折光仪可以进行的另一项关键任务是在反应和纯化步骤后测量异氰酸酯 MDI、甲苯二异氰酸酯 (TDI)、六亚甲基二异氰酸酯(HDI) 的浓度。这能确保将正确浓度的液体送入聚氨酯工艺过程。 原位在线折光仪还可以监测和控制进料催化剂或回收溶剂的浓度。 阅读应用说明,详细了解异氰酸酯和聚氨酯 (PU)生产中的测量。 填写表格,即可下载 PDF 格式的应用说明。 返回所有化学品和同类产品应用 Email Address*First Name*Last Name*Country*--Please Select--United StatesUnited KingdomCanadaChinaIndiaJapanAustraliaBrazilFranceGermanyFinland--------------AfghanistanÅland IslandsAlbaniaAlgeriaAmerican SamoaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBoliviaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBrit/Indian Ocean Terr.Brunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Dem.
