Description

A kind of processing method for improving handicraft raw material wicker PARA FORMALDEHYDE PRILLS(91,95) absorption property
Technical field
The present invention relates to wood artwork Feedstock treating technical field, and in particular to improves handicraft raw material willow for one kind The processing method of bar PARA FORMALDEHYDE PRILLS(91,95) absorption property.
Background technology
Wicker soft pliable, thickness are well-balanced, color and luster is graceful, by novel design, can be woven into various simple natural, moulding Attractive in appearance, Portable durable practical art product.Its product includes:Crate (bag), meal basket, food basket (circle, ellipse), bamboo strainer, needlework Shallow basket made of wicker or thin bamboo strips, kang mat, reed matting etc..Wicker plaiting article is one of folks of china traditional handicraft product, and people are intended only as common daily in ancient times Utility, until decades just gradually rise after 20th century, also gradually turn into the project that selected areas of China is exported goods and earned foreign currency.Entirely State-owned three big wicker plaiting article production base, Shandong, Henan, Anhui.
Before wicker plaiting article establishment, the processing to wicker is extremely crucial, in the prior art to improving wicker color the processing of wicker more Damp vividness, it is anti-mildew based on, there is certain limitation.
The content of the invention
To solve the limitation that existing wicker processing is present, handicraft is improved it is an object of the invention to provide one kind former Expect the processing method of wicker PARA FORMALDEHYDE PRILLS(91,95) absorption property.
The technical solution adopted by the present invention is, a kind of processing side for improving handicraft raw material wicker PARA FORMALDEHYDE PRILLS(91,95) absorption property Method, including following process step：
（1）Peeling is handled：Clip wicker, classifies by specification, and wicker is sent into closed chamber, ethene is sent into closed chamber, is made Ethylene contents reach 300-320ppm in sealing, handle 5-6 hours, wicker are taken out, peeling；
（2）Sofening treatment：Wicker is handled to 40-45 points under the vapours that pressure is 1.3-1.5Mpa, temperature is 130-140 DEG C Clock；
（3）Modification：It will be sprayed in wicker feeding spray chamber after processing so that wicker center water content is 96-98%；Will It is that spray process makes in 28-30%, circulation feeding spray chamber that wicker after spray process, which is dried in vacuum tank to center water content, It is 65-70% to obtain wicker center water content, and it is 13- that the wicker after spray process is dried to center water content in vacuum tank 15%；Spray process in spray chamber is fed again into so that wicker center water content is 30-32%, wicker most at last after spray process It is 10-12% to be dried in vacuum tank to center water content.
It is preferred that, the wicker clip time is that annual willow occurs before not bloomed after bud；
It is preferred that, spray liquid is that concentration is 0.4-0.5% disodium EDTA aquas, and spray liquid temperature is 26-28 DEG C；
It is preferred that, spray liquid is that concentration is 0.42% disodium EDTA aqua, and spray liquid temperature is 27 DEG C；
It is preferred that, vacuum drying tank temperature is 60-70 DEG C.
Beneficial effect of the present invention is that the wicker micro-pore diameter after being handled through present invention process has obtained significant raising, Resulting wicker specific surface area is between 500-560 ㎡/g, and PARA FORMALDEHYDE PRILLS(91,95) has preferable adsorption capacity, and resulting wicker is used In craft articles, air can also be purified while realizing sight；
When peeling is handled, in wicker feeding closed chamber, ethene is sent into closed chamber, ethylene contents in sealing is reached 300- 320ppm, is handled 5-6 hours, the wicker cortex after processing can be stripped easily, improves the integrality for peeling off Liu Xin；
Wicker is handled 40-45 minutes under the vapours that pressure is 1.3-1.5Mpa, temperature is 130-140 DEG C, realized to willow Bar softens, and spray liquid energy is fully infiltrated into Liu Xin central cores during beneficial to follow-up spray；
After the modified processing of wicker, specific surface area is significantly improved, and spray liquid is 0.4-0.5% ethylenediamine tetrems from concentration Acid disodium salt aqua, can strengthen wicker intensity, influence of the reduction modification to wicker intensity level, the wicker intensity after processing Value reduced by only 2.8-3.0% compared with before processing.
