Embodiment Construction

[0038] Below in conjunction with embodiment the present invention will be further described:

[0039] 1. The powdery sludge foaming agent ingredients are composed of the following components by weight percentage: sludge mixture 32%, high-viscosity attapulgite clay powder 8%, active attapulgite clay 18%, sodium lauryl sulfate 28% %, 12.3% sodium percarbonate, 0.8% sodium polyacrylate, 0.6% sodium pyrophosphate and 0.3% sodium polynaphthaldehyde sulfonate.

[0040] The production method of the sludge flame retardant foaming agent: input the ingredients of the sludge flame retardant foaming agent into the mixer for stirring, after stirring evenly, input it into the mill for grinding, the particle fineness is ≤0.044 mm, and pack it as sludge Finished product of flame retardant blowing agent.

[0041] The sludge mixture ingredients are composed of the following components by weight percentage: 78% of sludge and 22% of attapulgite clay tailings.

[0042] The production method of t...

Abstract

The invention discloses a powdery sludge foaming agent. Main points of the technical scheme are as follows: the powdery sludge foaming agent is composed of sludge, attapulgite tailings, a hyperviscous attapulgite powder, active attapulgite, sodium dodecyl sulfate, sodium percarbonate, sodium polyacrylat, sodium acid pyrophosphate and sodium poly(naphthaleneformaldehyde) sulfonate; and the above ingredients of the powdery sludge foaming agent undergo stirring, milling and packaging so as to obtain the finished product, namely the powdery sludge foaming agent. The powdery sludge foaming agent has advantages of strong foaming capability, high bubbling times, large quantity of foams produced per unit volume, good toughness of outer foam film capable of not being easily broken, good foam stability, no defoaming for a long time, fine foam, uniform size of pores generated inside a medium, low bleeding amount, good compatibility of the medium used and the like. Products produced by the use of the powdery sludge foaming agent can be used to effectively control noise pollution and also have functions of heat insulation and air purification. The powdery sludge foaming agent is suitable for production of lightweight sheet materials, lightweight wall and noise reduction products.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a powdery sludge foaming agent. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0003] To control noise, measures such as damping, sound insulation, sound absorption, muffler, personal protection, and building layout are usually taken to minimize or reduce the vibration of the sound source, absorb the sound energy in propagation, and set up obstacles to reflect all or part of the sound. Reduce the effect of noise to achieve the purpose of controlling noise. [0004] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and silencers to control noise pollution, and some materi...
