Breath.With the development of social economy, traditional wicker plaiting article production gradually develops into modern wicker plaiting article industry, is keeping traditional willow-plaited process
The cycle development of industry is realized on the basis of elite, the utilization rate for improving resource, the product for developing diversified forms, formation one
The development model for covering many industrial chains is the prerequisite of wicker plaiting article techno-globalism and the marketization.
Wicker as a kind of biological material, itself have it is perishable, go mouldy, absorb water, deforming, damaging by worms, change colour etc. inherently
Defect, wants to improve the performance of knitting, it is necessary to pre-process wicker, its some intrinsic defect is repaiied
Multiple, currently a popular processing mode is to carry out immersion modification to it using various chemical pretreatment solutions, although to a certain degree
On repaired these defects of wicker, it is but all more unilateral, be difficult to realize a comprehensive modification.CN103465329A
A kind of " Wood micro charring method " patented technology is disclosed, in atmospheric conditions, the timber after preheating is once heated up micro- charing
Processing, obtains the timber of the micro- charing in surface, the wood surface of micro- carbonization has the performances such as good anti-corrosion, insect prevention, protection against the tide, made
It is improved with performance, but is due to that wicker plaiting article raw material are more loose than the institutional framework of timber, is easier in temperature-rise period
Craze and transfiguration, causes charred effect not good, it is necessary to develop more suitable micro- charring process.
The content of the invention
There is provided a kind of micro- charing process technology in wicker plaiting article raw material surface for the defect that makes up prior art by the present invention.

Footpath is the alkaline silica sol between 10-50nm,
（3）It is 6.5-7.5 that appropriate hydrochloric acid regulation alkaline silica sol system pH, which is added dropwise, obtains Ludox impregnation process liquid standby；
（4）By step（1）Resulting material is put into impregnation process tank, then vacuumize process, and vacuum reaches -0.01--
Ludox impregnation process liquid is injected after 0.05MPa, then pressure keeps release after 20-30min to 0.1-0.5MPa, reclaims silicon
Sol impregnation treatment fluid, repeats above-mentioned dipping process and once discharges afterwards；
（5）Produced after charing process will be carried out in feeding carbonizing kiln after material normal temperature maintenance 24-48h after discharging.
Described step（2）Neutral and alkali Ludox pH value is 8.5, and density is 1.35g/cm3, dioxide-containing silica is 35%,
Silica particle diameter concentrates on 20-35nm.
Described step（3）The pH value of middle Ludox impregnation process liquid is 7.5.
Described step（5）In charing process process be：30-35 DEG C is first warming up to, forced convertion dried and risen after 2-3h
Temperature is to 80-85 DEG C, and 1-2h is dried in forced convertion, is then brought rapidly up to 130-150 DEG C, is incubated after micro- charing process 3-5min and closes
Thermal source is closed, is discharged when naturally cooling to less than 45-50 DEG C.
Described charing process process is：32.5 DEG C are first warming up to, forced convertion is warming up to 82.5 DEG C after drying 2.5h, by force
Convective drying 1.5h processed, is then brought rapidly up to 140 DEG C, closes thermal source after being incubated micro- charing process 4.5min, naturally cools to
Discharged at less than 50 DEG C.
Ludox impregnation process liquid is impregnated in wicker plaiting article raw material by the present invention by way of pressure, is effectively raised
The composite performance of wicker plaiting article raw material, its strength and stability is higher, is unlikely to deform and ftractures in thermal histories, after enhancing processing
Wicker plaiting article raw material be re-fed into carbonizing kiln the progress micro- charing process in surface, realized on the basis of wicker plaiting article raw material toughness is retained
The micro- charing process in surface, so as to improve, material is perishable, goes mouldy, absorb water, deforming, damaging by worms, change colour inherent shortcoming, and charing
Material afterwards has unique surface texture and color and luster, and intensity is also higher, not only uses personality more in baskets craft field
It is prominent, household material is also used as, good economic worth and practicality is had concurrently.
