Abstract
The present invention relates to a phosphorusless degreaser and a preparing method thereof. Polyether with low foam force and high degreasing performance is used as the main components of the phosphorusless degreaser having a formulation: 0.3 to 15 shares of polyether with different hydrophilic-lipophilic balance values, 0.1 to 4 shares of castor oil acid sodium sulfate, 0.1 to 18 shares of anhydrous sodium sulfate, 0.1 to 10 shares of sodium carbonate, 0.1 to 45 shares of sodium bicarbonate and fillers as the rest. The present invention is suitable for production in a large scale and a metal surface coating production line with full hermitic continuous jetting operation. The present invention has low foam, high efficiency and strong degreasing power, and the phosphorus content in discharged waste water fits the prescription of GB8978-88<integrated wastewater discharge standard> of China.
Description
Technical field:
The present invention relates to a kind of metallic substance clean-out system, mainly is that a kind of coating metal surfaces (plastic-blasting, spray paint, plating etc.) industry that is exclusively used in is carried out pretreated agent of non-phosphate degreasing of degreasing and manufacture method to workpiece.
Background technology:
In the prior art, all contain the anion surfactant sodium alkyl benzene sulfonate in the prescription of grease-removing agent.Though this tensio-active agent has very strong emulsifying power and degreasing power, froth stability too strong and calcium, magnesium ion that meet in the hard water can influence degreasing effect, must add the tripoly phosphate sodium STPP softening of water.This grease-removing agent deficiency is: in totally-enclosed streamline, a large amount of foams can be scurried on the equipment of later process, causes doing over again even stopping production, and only is only applicable to the little drill traverse interval type production of industrial scale; Phosphorus element content is 522mh/L-867mg/L in the grease-removing agent institute waste discharge of producing at present, surpasses about thousand times of national standard.And the waste water that contains phosphoric in a large number enters in the river, can make that the algae (biological self reproducing must have the synthetic thymus nucleic acid of being responsible for heredity of phosphoric) behind a large amount of absorption phosphoric in the water breeds in a large number with geometricprogression, causes water quality deterioration even turns black smelly.
Summary of the invention:
The present invention is in order to overcome the deficiency of above-mentioned prior art, and a kind of agent of non-phosphate degreasing is provided.It can adapt on a large scale, the production of the coating metal surfaces streamline of totally-enclosed continuous injection operation, and the content of phosphorus meets the regulation of GB8978-88 " integrated wastewater discharge standard " in the waste water of the strong and discharging of the efficient degreasing power of low bubble.
The present invention implements by the following technical programs.Prescription of the present invention has been selected the major ingredient of the polyethers (another name of polyethylene oxide-poly(propylene oxide) segmented copolymer) of low foam power and high degreasing performance as agent of non-phosphate degreasing for use, do not need to add tripoly phosphate sodium STPP again, thus the phosphoric problem that exceeds standard when fundamentally having solved discharge of wastewater.In the agent of non-phosphate degreasing of 100 parts of weight, contain:
0.3 to 15 part of polyethers;
Described polyethers is by three kinds of different HLB values, i.e. hydrophile-lipophile balance values
Polyether combined form: the HLB value is 3 to 5 0.1 to 2 parts;
The HLB value is 9 to 12 0.1 to 10 parts;
The HLB value is 14 0.1 to 3 parts;
0.1 to 4 part in ricinolic acid sodium sulfate;
0.1 to 18 part of anhydrous sodium sulphate;
0.1 to 10 part in yellow soda ash;
0.1 to 45 part of sodium bicarbonate;
Weighting agent can adopt 4A zeolite or diatomite or perlite breeze all the other.
The present invention can also come perfect by the following technical programs.Further perfect prescription is to contain in the agent of non-phosphate degreasing of 100 parts of weight:
Polyethers HLB value is 3 to 5 0.5 to 2 parts,
The HLB value is 9 to 12 1.0 to 10 parts,
The HLB value is 14 0.5 to 3 parts,
1.0 to 4 parts in ricinolic acid sodium sulfate,
1.0 to 18 parts of anhydrous sodium sulphate,
1.0 to 10 parts in yellow soda ash,
2.0 to 45 parts of sodium bicarbonates,
The 4A zeolite all the other.
Select the ricinolic acid sodium sulfate of low foam power for use, to promote the micelle-forming concentration of nonionic polyoxyalkylene surface active agent.Above-mentioned weighting agent can adopt 4A zeolite or diatomite or perlite breeze.
The present invention can make by following production method, at first anhydrous sodium sulphate, yellow soda ash, sodium bicarbonate and the weighting agent mixing back with predetermined weight is crushed to 60 to 80 orders with pulverizer, it is standby to put into mixing tank then, polyethers and ricinolic acid sodium sulfate with above-mentioned three kinds of different HLB values of predetermined weight is added in the reactor again, is steam heated to about 100 degrees centigrade the back and stirs 2 hours.And then with pump feed liquid is sprayed on the powder mix standby in the mixing tank, on one side spray, mixed 1 hour on one side, at last with material by behind 40 eye mesh screens product.
The present invention adopts the polyethers of different HLB combinations, has froth breaking and good degreasing effect voluntarily, is applicable in the totally enclosed streamline.The waste water that is discharged detects through Institute of Analysis of Zhejiang University, and phosphorus element-containing is 0.102mg/L in the waste water, is significantly less than the permissible value of standard GB 8978-88 regulation, reaches primary standard 0.5mg/L.
