The production technology of 2 high silica glass fiber yarns rope of embodiment
Acid leach: by tribasic sodium borosilicate fiberglass yarn rope (specification: BC8-220S120) with wind than for 3.14 around
On acidproof creel, wherein the creel section of selection is positive hexagonal structure, and the radius of the circumscribed circle of creel is 500cm, winding
Silvalin rope yarn layer with a thickness of 2.6cm, then creel is rotationally connected in acid leach slot by shaft；It is dense using equivalent
The hydrochloric acid solution is injected in resistance to heat exchanger after being heated to 50 DEG C as acid solution and injects acid by the hydrochloric acid solution that degree is 3.1N/L
In leaching tank；Then starting creel rotation, control creel velocity of rotation is 20rpm, while the acid solution in acid leach slot being passed through again
It crosses in pump input heat exchanger and carries out circulating-heating, until the temperature of acid solution is 95 DEG C, then maintaining acid liquor temperature is at 95 DEG C
Insulation reaction 100min.
Washing: after acid leach, the acid solution in acid leach slot being discharged, and is controlled creel and is rotated with the speed of 20rpm, together
When with 62 DEG C of water spray washing 10min is carried out to the surface of silvalin rope, 62 DEG C of water are then injected into acid leach slot to fibre
Yarn rope soaking and water washing 30min is tieed up, draining finishes, the water adsorbed in leaching dry fibers yarn rope, controls creel again later with 20rpm's
Speed rotation, while spray washing 10min is carried out with surface of 62 DEG C of the water to silvalin rope, then injected into acid leach slot
62 DEG C of water is to silvalin rope soaking and water washing 30min, and the pH value for measuring silvalin rope surface at this time is 6.8, and washing is completed.
Drying and sintering: the silvalin rope after washing being placed at 120 DEG C and dries 90min, removes the moisture of adsorption,
Then first sintering is carried out, rises to 600 DEG C from 120 DEG C with the heating rate of 6 DEG C/min, then keeps the temperature 30min, then carry out two
Secondary sintering is continued to be warming up to 730 DEG C from 600 DEG C with the heating rate of 4 DEG C/min, then keeps the temperature 30min, then naturally cool to
Room temperature, sintering finish.
Surface treatment: it using in the glue that single fiber yarn rope passes through steeping vat respectively and is immersed in steeping vat, carries out
Abundant impregnation, the glue are reinforced resins glue, are then dried in 150 DEG C of drying oven, then are rolled up with dividing sinker winding apparatus
