Description
Technical field
A kind of method of testing of the glass fiber yarn ball internal moisture baked the present invention relates to high frequency.
Background technology
The market demand of glass fiber direct roving is growing, and client is required also increasingly product quality
Height, bakes whether technique well has vital effect to glass fiber product quality.High frequency baking oven by its baking speed it is fast,
The advantages of product produces filoplume amount few, is increasingly becoming the baking equipment of some high-end glass fiber products.But high frequency is also because of its own
The characteristics of in the presence of certain baking blind spot, easily there is the internal phenomenon do not dried completely of yarn group.Surpass to avoid the occurrence of moisture content
Target quality problems, it is necessary to which the glass fibre yarn group inner aqueous rate baked to high frequency baking oven is measured.
" the enhanced article test method part 1s of GB/T 9914.1:Content disclosed in the measure of moisture content " is current
The water cut test method general for conventional glass fibers roving, the method summary that the standard is related to is as follows:From yarn group
Oven for drying is put on surface into after taking the yarn of certain length, yarn is weighed, and is re-weighed after taking-up, calculates moisture content.From taking
Quadrat method understand the standard can only in test yarns group certain length yarn moisture content, i.e., the water-bearing survey of conventional yarn group, without
The internal blind spot region water-bearing survey of yarn group under technique is baked suitable for high frequency.
The content of the invention
Its purpose of the invention is that the glass that a kind of high frequency provided to overcome the shortcomings of prior art to exist is baked
Glass silvalin rolls into a ball the method for testing of internal moisture.
The technical scheme realized above-mentioned purpose and take, a kind of test of the glass fiber yarn ball internal moisture that high frequency is baked
Method, described method of testing is carried out in the environment of 20-26 DEG C of temperature, humidity 55-75%, and method of testing includes following step
Suddenly:(1)Choose yarn group to be sampled:In the good glass fiber yarn ball of one outward appearance of high frequency baking oven egress selection, existed with signature pen
The position end face that yarn group contacts with support creel plate makes marks, and be shaped as and the yarn of the mark roll into a ball the straight line that diameter is essentially coincided, and use
Pyrocondensation bag installs yarn group to be removed from creel, delivers to doff area conditioning temperature;(2)Yarn group outer ring yarn removal to be sampled:To adjust
Manage to the yarn group of room temperature and be positioned on creel, remove pyrocondensation bag, mark is carried out in the end face rolled into a ball apart from yarn at the 1cm of outer ring with signature pen
Note, starts to remove outer ring yarn with winder, untill the 1cm marks of end face;(3)It is determined that digging sampling point position:From step
(1)In the end face mark that does start, along yarn group end face, every 90 ° determine point position, then four point positions altogether, with end face each
Draw the rectangle frame of 10cm*5cm on corresponding yarn group surface centered on point position, by four points position opsition dependents numberings be 1#, 2#,
3#, 4#, and indicated on the label of counter sample hermetic bag, in case obscuring;(4)Take test sample:With cutting wire knife along 1#
The inner edge of point bit length square box is exerted oneself to draw, it is ensured that each edge is all drawn to depth 1cm, has thus been obtained volume profiles and has been
The glass filoselle of 10cm*5cm*1cm, rapidly digs out filoselle, is put into sealing in 1# hermetic bags;Dig out successively as stated above
The sample of 2#, 3#, 4# rectangle frame, is put into correspondence hermetic bag, and sample is delivered into physical property sensing chamber moisture content to be measured rapidly;(5)
Carry out water cut test:Four planchets are taken out from drier, with scales/electronic balance weighing, M is recorded as;Again from four hermetic bags
Take out sample segment respectively to be sequentially placed into four planchets, record claims to obtain gross weight M1;Sample is put into together with planchet
Temperature is set as in 105 DEG C of baking oven that dry more than one hour, taking-up is weighed and carries out being recorded as M2, then moisture content H=(M2-
M)/(M1-M);(6)Data analysis:Contrast four moisture content of sample and index of dispatching from the factory, it is known that this test data is as good as
Often, judge that the product bakes working well property.
Beneficial effect
The present invention has advantages below compared with prior art.
1st, the moisture content inside high frequency baking yarn group can be in time measured, quality is asked caused by being prevented effectively from because baking not exclusively
Topic;
2nd, contribute to promoting the use of for high frequency baking oven, high frequency can be given full play to and baked that the product filoplume amount that has of technique is few, baked
The advantages of speed is fast, effectively improves product quality and yield.
