Description
Technical field
The present invention relates to sizing agent detection fields more particularly to sizing agent to impregnate detection method.
Background technique
Latex fiber plate is a kind of sheet material being combined using plant fiber and latex, have good processing and
Service performance.It is mainly used in the interior bottom of production shoes at present, is also applicable in luggage, belt, clothing, shoes and hats, the brim of a hat, stationery
Inner lining material, the making material of furniture etc., the label etc. of jeans.
Making sizing agent used in latex fiber plate includes: dispersion rosin size, paraffin wax emulsions sizing agent, alkyl ketene two
Polymers (AKD), alkenyl succinic anhydride (ASA), modified starch.Latex fiber plate or Paper or cardboard need to have in use
Water-resistance, and it is glued the water-resistance that can be improved latex fiber plate or Paper or cardboard, make product that there is required service performance,
To control water, ink, blood, soft drink and the infiltration of other liquid.
But its internal performance is different due to various sizing agents, the sizing agent quality of different manufacturers production is had any different again, such as
What, which judges whether a kind of visual angle agent effect generated in vegetable fibre board is added and the product quality reached meet, presets
Standard, current most of latex fiber plates manufacturer is tested using the method for upper machine pilot scale, if sentenced in advance
Whether disconnected or selection sizing agent is suitable, it is necessary to which on the one hand repeated multiple times ground machine test seriously affects normal production, another party
Face experimentation cost is very high.
Summary of the invention
It is an object of the invention to propose that one kind imitates actual production first with sizing agent to be detected, drafting board to be checked is obtained,
Detection data is obtained by detecting the partial properties of drafting board to be checked again, is finally produced with known suitable sizing agent to be checked
The critical field data of drafting board compare, to judge that the sizing agent to be measured is soaked if appropriate for the sizing agent of Fibreboard Production
Steep detection method.
To achieve this purpose, the present invention adopts the following technical scheme:
Sizing agent impregnates detection method, includes the following steps:
1) detection of sizing agent to be detected:
A), sizing solution to be detected is prepared, and is put into container；
B), a piece of cardboard is unfolded in merging container, and sizing solution to be detected is made to be totally submerged cardboard；
C), fully absorbed after sizing solution to be detected becomes wet paperboard, taken out after cardboard；
D), wet paperboard is tiled across pressurizing unit, squeezes and remove extra sizing solution to be detected, forms half-dried cardboard；
E), half-dried cardboard is put into drying in oven, obtains drafting board to be checked；
F), treat detection plate to be detected, obtain detection data；
2), the detection of standard sizing agent:
G), the sizing solution to be detected in the step 1) is changed into the standard sizing solution of suitable Fibreboard Production, and
According to the step a)-f) repeated detection is carried out, and obtain critical field data；
3), the detection data is compared with critical field data, it was therefore concluded that.
More preferably, the step 1) and 2) in no particular order.The step 1) described in actually detected and 2) be it is independent, it is same
After the completion of standard sizing agent known to kind is according to step 1) operation, obtained critical field data can be saved, directly
The contrast standard range data for connecing the detection data as later similar sizing agent to be detected does not just have to do a standard every time
The detection process of sizing agent.
It further illustrates, the latex concentration of the sizing solution to be detected and standard sizing solution that are placed in container is
15-45%.The concentration of sizing solution to be detected or standard sizing solution is limited in the range, is to imitate reality
Concentration when sizing solution adds in production.
It further illustrates, the standard sizing agent is by dispersion rosin size, paraffin wax emulsions sizing agent, alkyl ketene dimer
(AKD), at least one of alkenyl succinic anhydride (ASA), modified starch sizing agent form.
The cardboard is the A4 blank sheet of paper with a thickness of 0.1mm-1.5mm.Using the A4 blank sheet of paper in this thickness range, a side
Face be it is very common, convenient for experiment materials, having can save the cost；On the other hand be the test made of this thickness range at present
It can reflect required result.
It further illustrates, it is 1- that cardboard, which immerses sizing solution to be detected or the time of standard sizing solution, in step c)
5 minutes.Soaking time of the cardboard in sizing solution is very crucial, and soaking time is too short to allow cardboard to fully absorb sizing agent
Solution；Long soaking time will lead to cardboard water suction excessive deformation, influence subsequent experimental operation.
A kind of pressurizing unit impregnating detection method applied to above-mentioned sizing agent, the pressurizing unit include above and below a pair of
The compression roller of face setting, upper roller is rubber covered roll, and lower roll is chrome-plated roller, and the line pressure of 0.5-1.0kg/cm is given between two rollers.
Squeeze pressure is adjusted according to experiment actual conditions, makes to squeeze out the sizing agent being retained in after extra latex solution in wet Paper or cardboard
Content meets design requirement.
More preferably, the pressurizing unit is arranged right below adapter road, the cavity in the adapter road and the container
Connection.Extra sizing solution in wet paperboard is recovered in container, waste is avoided, has saved experimental cost.
It further illustrates, the baking temperature of baking oven is 100-110 degree in the step e).The baking temperature of baking oven is limited
In the range, be with reference to national standard " measurement of 462 paper of GB/T, cardboard and pulp analysis sample moisture " requirement to
Out.
More preferably, every kind of sizing agent to be detected needs at least step 1) in triplicate, will obtain three testing results and asks
Detection data of the average value out as sizing agent to be detected described in every kind, then with the critical field data comparison.By more
Secondary repeatability detection, could eliminate the manual operation error in detection process, detection that could be more objective and accurate as far as possible
The drafting board various performance parameters to be checked that sizing solution is produced out.
The present invention proposes that a kind of sizing agent impregnates detection method according to above content, is to imitate actual production situation, raw
The drafting board to be checked of output detects that the performance data of drafting board to be checked is institute finally according to existing paperboard properties detection method
State detection data.Sizing agent performance test is first detected in laboratory, then will test data and known suitable fibers
The corresponding critical field data of sizing agent of plate production are compared, and then judge whether sizing agent to be detected is adapted to fiber
The production of plate；In this way can be repeated multiple times constantly to be tested in the case where lesser experimentation cost, it is closed until testing out
Suitable sizing agent prescription avoids machine production detection on sizing agent to be detected directly, detection and production cost is greatly saved.
Detailed description of the invention
