Choosing better organic solvents and providing appropriate mixing ratios for nitrocellulose (NC) lacquer thinner is a very important topic in NC lacquer thinner industries. This paper studied the effects of cosolvents and non-solvents on ester true solvents in NC lacquer thinner. The research objects were ester true solvents (Methyl Acetate (MA) and Ethyl Acetate (EA)), alcohol cosolvents (Ethyl Alcohol (ETA), Isopropyl Alcohol (IPA), and Isobutyl Alcohol (IBA)) and non-solvents (n-Hexane (NX), n-Heptane (NP), and Petroleum Ether (PE)). Nitrocellulose lacquer dissolution experiments, explosion characteristic experiments, and algal growth inhibition experiments were performed. The results indicated that: the mixed organic solvents containing cosolvent of ETA were better than those containing the other two cosolvents (IPA and IBA) in terms of dissolution rates, explosion characteristics, and environmental influences. For non-solvent, NX was a better non-solvent as the dissolution rates of mixed organic solvents (containing MA, ETA, and NX) all kept at relatively higher levels at different non-solvent proportions. NX and PE were safer non-solvents when the concentration of non-solvent was relatively lower (16.7 %). The IC₅₀ values of mixed organic solvents containing non-solvent NT on Dunaliella bardawil were a little bit higher than those of mixed organic solvents containing NX or PE when the volume ratios of non-solvent were the same. In conclusion, the mixed organic solvent of MA (ester true solvent), ETA (alcohol cosolvent), and NX (non-solvent) with a volume ratio of about 4:1:1 was a relatively ideal composition for the industrial application of NC lacquer thinner.

选择更好的有机溶剂并为硝化纤维（NC）漆稀释剂提供合适的混合比例是NC漆稀释剂行业非常重要的课题。本文研究了助溶剂和非溶剂对NC漆稀释剂中酯类真溶剂的影响。研究对象为酯类真溶剂（乙酸甲酯（MA）和乙酸乙酯（EA））、醇类助溶剂（乙醇（ETA）、异丙醇（IPA）和异丁醇（IBA））和非溶剂（n-己烷 (NX)、正庚烷 (NP) 和石油醚 (PE)。进行了硝化纤维素漆溶解实验、爆炸特性实验和藻类生长抑制实验。结果表明：在溶解速率、爆炸特性和环境影响方面，含有 ETA 助溶剂的混合有机溶剂优于含有其他两种助溶剂（IPA 和 IBA）的混合有机溶剂。对于非溶剂，NX 是一种更好的非溶剂，因为混合有机溶剂（包含 MA、ETA 和 NX）的溶解速率在不同的非溶剂比例下都保持在相对较高的水平。当非溶剂浓度相对较低（16.7%）时，NX 和 PE 是更安全的非溶剂。集成电路 当非溶剂浓度相对较低（16.7%）时，NX 和 PE 是更安全的非溶剂。集成电路 当非溶剂浓度相对较低（16.7%）时，NX 和 PE 是更安全的非溶剂。集成电路在非溶剂体积比相同的情况下，含有非溶剂NT的混合有机溶剂对杜氏杜氏藻的_{50值均略高于含有NX或PE的混合有机溶剂。}综上所述，MA（酯类真溶剂）、ETA（醇类助溶剂）和NX（非溶剂）体积比约为4:1:1的混合有机溶剂是NC工业应用较为理想的组成。漆稀释剂。
