一种减水剂实验合成用滴液装置
:本技术涉及实验室反应液体滴加
,具体涉及一种减水剂实验合成用滴液装置。
技术介绍
:减水剂是一种在维持混凝土坍落度基本不变的条件下,能减少拌合用水量的混凝土外加剂。为了进一步提高减水剂的效果,科研人员正在研制早强保坍型聚羧酸减水剂,在研制早强保坍型聚羧酸减水剂的过程中经常需要进行合成实验,再合成过程中有时不仅需要同时滴加多种组分,而且也要对各组分的滴加流速进行精确控制,而目前普遍采用的滴液设备为恒压滴液漏斗,现有恒压滴液漏斗一个只能滴加一种液体,因此当需要同时滴加多种组分时,要用多个恒压滴液漏斗,而合成用的烧瓶通常为三颈烧瓶或四颈烧瓶,烧瓶上还要留有搅拌和温度测量瓶颈,因此导致瓶颈不够用的问题,同时现有的恒压滴液漏斗对于流速控制精度不高,误差较大。
技术实现思路
:本技术的目的就是为了弥补现有技术的不足,提供了一种减水剂实验合成用滴液装置,它具有结构设计合理、同时滴加多种组分、流速控制精确等优点,解决了现有技术中存在的问题。本技术为解决上述技术问题所采用的技术方案是:一种减水剂实验合成用滴液装置,包括支撑架,支撑架上设有储液瓶架,储液 ...
