Description

Without phosphorus oil-bound distemper and the without phosphorus oil removing process of removing
Technical field
The present invention relates to without phosphorus oil-bound distemper and the without phosphorus oil removing process of removing.
Background technology
Because phosphoric acid salt has sequestering power, wash-aid effect preferably, it is widely used in fields such as traditional industry after being re-dubbed clean-out system as a kind of washing assistant and tensio-active agent etc.Yet, because it is phosphorous in this kind clean-out system, after it is discharged away as waste water, can make body eutrophication, cause waterplant such as algae to breed in a large number, and the aerobic repiration of plant materials will consume oxygen a large amount of in the water, and the hydrocoles anoxic is caused death and produce a series of natural disaster (the blue-green algae incident that repeatedly breaks out as Taihu Lake, Jiangsu, Chaohu, Anhui, Dian Chi, Yunnan etc., and global marine red tide phenomenon etc.), badly influenced human safe drinking water.
Since the nineties in last century, more and more enterprises begins to research and develop without phosphorus clean-out system, the exploitation of the without phosphorus clean-out system of electroplating industry pre-treatment then starts from late nineteen nineties, yet, the phosphate builders because the builder as substitute for phosphate that is adopted can't match in excellence or beauty on over-all propertieies such as wash-aid effect, sequestering power, flush away is not so still there is to replace fully the pre-electroplating treatment product of phosphorous hydrochlorate oil removing powder so far.
Summary of the invention
The purpose of this invention is to provide a kind of without phosphorus oil-bound distemper and without phosphorus oil removing process of removing.
The technical solution used in the present invention is:
A kind of without phosphorus except that oil-bound distemper, comprise the raw material of following mass parts: 10~25 parts sodium hydroxide, 20~30 parts yellow soda ash, 20~35 parts non-phosphorus builder, 5~10 parts of sodium sulfate, 1~5 part of Trisodium Citrate, 1~5 part of Sunmorl N 60S, 6~12 parts of tensio-active agents.
Non-phosphorus builder is at least a in C2~8 carboxylic acids, the siliceous carboxyl acid modified thing in C2~8, toxilic acid/acrylic copolymer, the molecular sieve.
