Description

A kind of formula and its manufacturing process of benzaldehyde scavenger
Technical field
The present invention relates to one kind to remove agent prescription, the more particularly to a kind of formula and its manufacturing process of benzaldehyde scavenger.
Background technology
Formaldehyde is colourless gas, there is special penetrating odor, has stimulation to human eye, nose etc..Gas relative density is small. Soluble easily in water and ethanol.The concentration of aqueous solution reaches as high as 55%, is typically 40%, is referred to as formalin, is commonly called as formalin, is to have The colourless liquid of penetrating odor.Formaldehyde also has strong reducing action, particularly in alkaline solution.Can burning, steam and air Form explosive mixture, explosion limit 7%-73%(Volume).About 300 DEG C of ignition temperature.Formaldehyde can be by methanol in gold such as silver, copper Belong to the lower dehydrogenation of catalysis or oxidation is made, can also be separated by hydrocarbon oxidation product.With used as pesticides and disinfectant, phenolic resin processed, urea The raw material of urea formaldehyde, polyvinyl, methenamine, pentaerythrite and dyestuff etc..The formaldehyde damaged in life to human body, it may be said that It is ubiquitous.The article being related to includes furniture, timber floor;Children's garment, wash-and-wear of shirt;Instant noodles, rice flour;Bubble squid, sea cucumber, Omasum, peeled shrimp;Even car.It is not difficult to find out, food, clothing, housing and transportation --- we live most important four things, and formaldehyde is unexpectedly So all have a finger in every pie.The main harm of formaldehyde shows as reaching a certain concentration indoors to mucocutaneous stimulation, formaldehyde When, people just has sense of discomfort.Concentration of formaldehyde more than 0.08m3 can cause furious, eye to be itched, throat discomfort or pain, hoarseness, Sneeze, uncomfortable in chest, asthma, dermatitis etc..Newly-decorated room content of formaldehyde is higher, is the main inducing of numerous diseases.Concentration of formaldehyde It is excessive to cause acute poisoning, show as throat burning pain, expiratory dyspnea, pulmonary edema, anaphylactoid purpura, allergic dermatitis, liver Transaminase rise, jaundice etc..
Ubiquitous formaldehyde makes people weighed down with anxieties, therefore it is desirable to have a kind of cleaning agent that can remove formaldehyde to inhale Receive, neutralize formaldehyde, so as to obtain preferably life effect.
The content of the invention
The present invention provides a kind of formula and its manufacturing process of benzaldehyde scavenger, air middle reaches not only can be quickly caught From the formaldehyde under state, benzene homologues, TVOC etc., decomposed, while material internal can be infiltrated into and adsorbed, and formed Pollutant volatilization passage, accelerates volatilization, so as to achieve the purpose that to remove the pollutants such as the formaldehyde, benzene homologues, TVOC of material depths.
