Abstract
The invention discloses filter paper for oil mist in air and a producing process thereof. The filter paper for oil mist in air is made of raw materials, by mass percentage, 40%-70% of glass fibers, 30%-60% of PP or PET fibers. The producing process of the filter paper for oil mist in air includes the following steps of 1) proportioning and weighing the glass fibers and the PP (propene polymer)or PET (polyethylene terephthalate) fibers and mixing the same to make pulp; 2) diluting the pulp prepared from the step 1) and then removing residue in the pulp; and 3) forming the diluted liquid from the step 2) by a forming screen and then dewatering the same to obtain the filter paper for oil mist in air. The PP or PET fibers added in the filter paper for oil mist in air are smooth in surface and have functions as guide tubes in the filter paper, and accordingly the filter paper for oil mist in air is high in filter precision and efficiency, oil mist cannot attach onto the surfaces of filter materials or inside thereof, the service life of the filter materials can be prolonged, and the oil mist can be recovered after being condensed.
Description
Technical field
The present invention relates to a kind of mist of oil filtering material, be specifically related to a kind of air mist of oil filter paper and preparation method thereof.
Background technology
Mist of oil is to cause subject matter of air-polluting, and the generation of cutting fluid mist of oil possibly cause huge disaster hidden-trouble, has simultaneously to cause easily on the floor of mist of oil to fall down, and the air that contains mist of oil is discharged the workshop, also can cause the pollution of environment; The maximum harm of cutting fluid mist of oil is that also workers with long time exposure is easy to generate various diseases, like anaphylaxis dermatosis and malignant tumour etc., and possibly cause genetic disease.The generation of mist of oil is not only to be produced by cutting oil, also relates to industries such as diet, machining, pharmacy, biology, and it is extensive to relate to the field, and the pollution that causes is also serious, has brought very big influence to people's life and environment.
Therefore, to the contaminated with oil mist problem of above industry, need the effective mist of oil filtering material of exploitation.Occurred a lot of oily filter papers both at home and abroad, but these filter papers relate generally to the liquid oil filtration; And use common oily filter paper, mist of oil influences filtering accuracy attached to filter material surface or inner, and windage increases simultaneously, and material is changed frequent.
Summary of the invention
In view of this, the invention provides a kind of air mist of oil filter paper and preparation method thereof, filtering accuracy and filter efficiency are high, and mist of oil can be attached to filter material surface or inner simultaneously, and increase service life greatly.
