摘要:BTFTM稀释水控制技术中的BTFTM中央布浆器取代了传统流浆箱的锥形进浆总管，BTFTM稀释水控制系统取代了传统流浆箱的唇板调节系统，以达到对纸幅的横幅定量控制。BTFTM稀释水控制系统可以对几乎任何类型的流浆箱进行改造；亦可作为一台全新的水力式流浆箱配套设备。BTFTM稀释水控制技术已应用在全球190多台纸机上，显著地改善了纸张横幅定量差，提高了纸张质量。

Abstract:The BTFTM dilution control technology consists of a radial distributor, which replaces the headbox tapered header, and a dilution water system, which replaces slice lip profiling to control the basis weight profile. This system can be retrofitted to almost any type of existing headbox, or it can be supplied with a new hydraulic headbox. The technology has been installed on more than 190 paper machines worldwide and has provided substantial improvements in CD profile and in sheet quality.
