Abstract
The invention relates to a process for aftertreatment of a whole roll of glass fiber grey cloth. The process comprises the following steps: (1) preparation prior to operation; (2) preparation of acid leaching solution; (3) acid leaching of glass fiber grey cloth; (4) heat cleaning; (5) drying and sintering treatment; and (6) product inspection. The process has the advantages that a ceramic tube resistant to acid and high temperature is adopted, so that the glass fiber grey cloth does not need to be unfolded, and the whole roll of grey cloth can directly undergo aftertreatment. Therefore, the treatment time is shortened, and the whole roll of glass fiber grey cloth is also easy to operate. According to the process, the acid leaching, drying and sintering treatment conditions are improved, the treated product is flat in appearance and uniform in color, and the surface is smooth and flexible.
Description
Technical field
The invention belongs to extraordinary field of new, more particularly to a kind of aftertreatment technology of glass fibre fabric entire volume.
Background technology
Glass fabric has the advantages that high temperature resistant, resistance to ablation, thermal insulation, fire prevention, at relatively high temperatures with stable heat
Performance and dielectric properties.It is widely used in the fields such as heat-insulated and military project, the aviation of instrument and electronic device.So it is necessary to right
Glass fibre fabric carries out subsequent treatment.
At present, the aftertreatment technology of glass fibre fabric：The glass fibre fabric of entire volume is launched, pickling casing is put into
It is interior, then add certain density acid, plus hot acid to desired temperature in casing, keeping temperature is until acid leach is completed；Then
Glass fibre fabric is placed on warm wash equipment until cleaning is completed；Glass fabric after washing, by drying sintering
All-in-one oven is dried, sintering processes.This technique is primarily present problems with：（1）Entire volume cloth is launched in operation, is located afterwards
Reason terminates again to wind cloth, so operating process is cumbersome, spends the time longer；（2）Pickling and drying, the bar of sintering processes
Part is not perfect enough, causes the outward appearance of product not smooth enough, and color even has been short of and surface irregularity.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind can shorten process time, simple process and can produce excellent
Deng the aftertreatment technology of the glass fibre fabric entire volume of product.
To solve above-mentioned technical problem, the technical scheme is that：A kind of post processing work of glass fibre fabric entire volume
Skill, its innovative point is to comprise the following steps that：
（1）Prepare before operation：Unreeling shaft is penetrated in the paper tube of fabric, is placed in the fulcrum bearing on rear side of the machine of falling cloth fixed
It is good；The earthenware of acid-resistant and anti-high-temperature is put on winding off spindle, by fabric through on the Scroll before machine, the left and right of fabric is adjusted
Size, with wrench flange plate fixed screw is tightened, and is finally pasted onto in the glass fibre fabric leftover of bolt of cloth with glass fibre single-coated foam
On earthenware；The long table of the machine of falling cloth meter is reset, the working condition of length-counted device is checked and mix up, slow cloth of driving；
（2）The preparation of acid leached solution：With high purity hydrochloric acid and pure water mixed preparing, it is configured to concentration for 1.45～
1.75mol/L acid leached solution；
（3）Glass fibre fabric acid leach：Entire volume glass fibre fabric is put in acid leached solution tank-washer body, acid is opened
Leaching solution pump, acid leached solution is pumped in acid leached solution tank-washer, treats that acid leached solution is flowed into back from spout hole in casing
When in acid tube, start glass fibre fabric acid leach；
（4）Warm wash：Using by the hot clean water of vapor-water heat exchanger, immersion treatment glass is carried out on warm wash equipment
Fiber cloth, repeated washing 2～4 times, to the pH=6-7 of rinse water；
（5）Drying, sintering processes：Glass fabric after washing, entire volume carries out first by drying sintering integrated furnace
It is secondary to rise gentle second intensification, remove moisture content and simultaneously sinter sizing；
（6）The examination and test of products：The outward appearance and physicochemical property of product are tested, is met the requirements, carried out finished product packing, enter
Storehouse；It is undesirable, then carry out substandard product disposal.
Further, the step（2）High purity hydrochloric acid percent concentration be >=31%.
Further, the step（3）Acid leach in acid leached solution temperature be 92～98 DEG C, the time of acid leach is
105～115min.
Further, the step（4）Warm wash temperature be 65～75 DEG C.
Further, the step（5）First time be warming up to 120～150 DEG C, the heating-up time is 90min, temperature retention time
For 30min；610 DEG C are warming up to for the second time, the heating-up time is 480min, temperature retention time is 150min.
It is an advantage of the current invention that：
（1）Relative to traditional technique, this technique adopts the earthenware of acid-resistant and anti-high-temperature, thus need not be by glass fibre
Fabric launches, and entire volume fabric can directly be carried out post processing, thus, process time is shortened, it is also easy to operation；
（2）Relative to traditional technique, this technique strictly controls acid leach condition, can well remove the oxidation on surface
Thing thin film；
（3）Relative to traditional technique, this technique is improved to drying, sintering processes, is once heated up by original
Switch to carry out substep intensification twice so that process more perfect, the product appearance Jing after processing is smooth, color even, surface light
It is sliding soft.
