Embodiment 1

[0035] Take 85% of water by weight percentage (the same below), 0.75% of sodium hydroxide, 0.8% of anhydrous sodium silicate, 0.3% of phenylacryltriazole, 0.55% of ethylenediaminetetraacetic acid, and 10.4% of surfactant (of which twelve Alkylbenzenesulfonic acid 1.8%, nonyl polyoxyethylene ether (NP-10) 8.6%,) and then take 2.2% sodium hydroxide. Put the above raw materials into the stirring tank in the order described under normal temperature and pressure, stir for 20 minutes each time, and finally stir until it is colorless and transparent. This embodiment is tested according to the requirements of Q / OCKX001-2007, and the cleaning rate is 98%.

Embodiment 2

[0037] By weight percentage (the same below) take water 83.3%, sodium hydroxide 0.5%, anhydrous sodium silicate 1.8%, benzotriazole 0.4%, ethylenediaminetetraacetic acid 0.5%, surfactant 11% (of which twelve Alkylbenzene sulfonic acid 1.4%, nonyl polyoxyethylene ether (NP-10) 9.6%); then take 2.5% sodium hydroxide. Put the above raw materials into the stirring tank in the order described under normal temperature and pressure, stir for 20 minutes each time, and finally stir until it is colorless and transparent. This embodiment is tested according to the requirements of Q / OCKX001-2007, and the cleaning rate is 97%.

Embodiment 3

[0039] Take 86.5% of water by weight (the same below), 0.65% of sodium hydroxide, 1.2% of anhydrous sodium silicate, 0.2% of benzotriazole, 0.65% of ethylenediaminetetraacetic acid, and 9.2% of surfactant (of which twelve Alkylbenzene sulfonic acid 1.2%, nonylphenol polyoxyethylene ether (NP-10) 8%,); then take sodium hydroxide 1.6%,. Put the above raw materials into the stirring tank in the order described under normal temperature and pressure, stir for 20 minutes each time, and finally stir until it is colorless and transparent. This embodiment is tested according to the requirements of Q / OCKX001-2007, and the cleaning rate is 97.5%.

Abstract

The invention relates to a cleaning agent for papermaking felt, which comprises the following components in percentage by weight: 6.6-15.4% of surfactant, 0.1-0.6% of benzotriazole, 0.4-2.7% of anhydrous sodium silicate, 1.15-4.55% of sodium hydroxide, 0.25-0.95% of ethylenediamine tetraacetic acid and the balance of water. The surfactant is dodecylbenzene sulfonic acid and nonylphenol polyethenoxy ether. The water-based cleaning agent for papermaking felt has the advantages of energy saving, environmental protection, low price and high efficiency, and can replace the traditional products. The product can effectively clean various papermaking felt stemmings and complex-composition felt dirt, is universal for various types of papermaking felt, has high safe dilution rate, and does not damage the felt and the press roll surfaces.

Description

technical field [0001] The invention relates to a cleaning product for a papermaking felt, which is mainly used for cleaning the blockages of the papermaking felt, so as to improve the vacuum degree of the papermaking felt and enhance the water absorption capacity of the papermaking felt. Background technique [0002] Papermaking is one of the four great inventions of ancient Chinese science and technology, and it is also an outstanding contribution made by the Chinese to the development of world science and culture. The paper industry is an important basic raw material industry that is closely related to the development of the national economy and social undertakings. The consumption level of paper and paper is a symbol to measure the level of modernization and civilization of a country. [0003] Since 2010, my country's paper industry has experienced structural adjustment, energy conservation and emission reduction, and the elimination of backward production capacity. Infl...
