  1. In this paper, concentrated sulfuric acid and titanium dioxide are used to prepare the tios04 solution that test later required under long time heat. the influences of reaction time and reaction temperature to yield of tioso4 are discussed. in the experiment of preparing tio2 powder, reaction temperature, ph values, material ratio, operation way, velocity of feed, calcining heat and time are researched by the principle of nucleation and growth in thermodynamics and kinetics

    在制備tio _ 2粉體實驗中，根據成核生長的熱力學和動力學原理，深入分析了沉澱反應時環境的溫度、 ph值、反應物配比、操作方式、加料速度等因素對ti （ oh ） _ 4粒度的影響，以及焙燒溫度和保溫時間等因素對制得的納米tio _ 2粉體性能的影響，得出了制備銳鈦型納米tio _ 2粉體的優化工藝條件。
  2. Brushed with the thickness of 1. 5 ~ 2. 0mm. it can improve the impermeability pressure up 3 times that of blank samples ; the crystalline reaction can continuously carry out, sealing the crack and waterproofing for ever if water is existent ; very good environmental adaptability, and can be used as normal at ph 3. 0 ~ 12. 0 ; moreover, the contrast tests of the performance of pt coating with two kinds of widely used waterproofing coating xypex and coprox were also carried out in this paper. test results show that the properties such as impermeability, self - rehabilitating ability and corrosion resistance are superior to those of the counterparts

    試驗結果表明， pt防水塗料具有如下的性能特點：具有良好的防水性能，塗刷厚度1 . 5 2 . 0mm ，抗滲壓力可提高3倍以上；在有水的條件下，結晶反應可以不斷進行，能實現自愈合、永久性防水；具有很強的環境適應性，在ph值3 . 0 12 . 0條件下均可正常使用；此外，本文還進行了pt防水塗料與同類型防水材料xypex和防水寶（二者都是目前應用廣泛的防水塗料）的性能對比試驗。
  3. Test method for properties of investment casting slurry - part 4 : the ph test paper method for the determination of acidity

    熔模鑄造塗料性能試驗方法第4部分: ph試紙法測定酸度
  4. For settle a great deal popularize and apply exterior wall coating, this paper study on acid rain - resistant, pollute - resistant, false accelerated aging - resistant of them. therein to, acid rain - resistant test is acid rain simulate test by environment quality data in chongqing. ph value is partly 0. 690, 0. 610, 0. 613, 0. 453

    為了解決重慶市外墻塗料不能大量推廣應用外墻塗料的重大難題，本文主要試驗研究三種不同主要成膜物（純丙、硅丙、氟樹脂）的外墻塗料的耐酸雨性、耐沾污性、耐人工加速老化等三大技術性能指標，其中耐酸雨性實驗是根據重慶市環境質量數據進行的酸雨模擬實驗， ph值分別為0 . 690 、 0 . 610 、 0 . 613 、 0 . 453 。
