 东丽TORAY TMG20D-440：核心性能参数与严苛品质管控，彰显国际水准（Core Performance Parameters and Strict Quality Control, Demonstrating International Standards）

中文：东丽TORAY TMG20D-440严格执行东丽全球统一品质标准，全生产流程采用高精度自动化生产线，从膜材料配方、成膜工艺到元件卷制，每一个环节都经过严苛把控，确保每一支膜元件的性能一致性与可靠性[1][4]。该膜元件最大操作压力可达600psi（4.1MPa），最高进水温度113°F（45℃），连续运行pH范围2~11，单个膜元件最大压力损失不超过15psi（0.1MPa），单支压力容器最大压力损失不超过50psi（0.34MPa），最大进水SDI≤5，可适配多种复杂运行工况[1][6]。每一支膜元件出厂前均经过通水测试，采用专用保护液处理并真空包装，确保产品出厂状态优良，且部分美国生产型号通过NSF/ANSI 61饮用水认证，依托严苛的品控体系，在全球工业市场赢得稳定口碑[1][4]。其8英寸标准尺寸，直径7.9英寸（201mm）、长度40英寸（1016mm），适配各类标准8英寸压力容器，安装便捷[1][6]。

英文：TORAY TMG20D-440 strictly implements Toray’s global unified quality standards. The entire production process adopts high-precision automated production lines. Every link from membrane material formulation, film formation process to element winding is strictly controlled to ensure the performance consistency and reliability of each membrane element [1][4]. The maximum operating pressure of this membrane element can reach 600psi (4.1MPa), the maximum inlet water temperature is 113°F (45℃), the continuous operation pH range is 2~11, the maximum pressure loss of a single membrane element is not more than 15psi (0.1MPa), the maximum pressure loss of a single pressure vessel is not more than 50psi (0.34MPa), and the maximum inlet water SDI≤5, which can adapt to various complex operating conditions [1][6]. Each membrane element undergoes water passing test before leaving the factory, is treated with special protective fluid and vacuum packed to ensure excellent factory state. Some models produced in the United States have passed NSF/ANSI 61 drinking water certification. Relying on the strict quality control system, it has won a stable reputation in the global industrial market [1][4]. Its standard 8-inch size, with a diameter of 7.9 inches (201mm) and a length of 40 inches (1016mm), is compatible with various standard 8-inch pressure vessels and easy to install
