Description

One kind removing formaldehyde shell powder paint production method

Technical field

The invention belongs to shell finishing technology fields, are specifically related to a kind of production method except formaldehyde conch meal.

Background technique

The purposes of conch meal has very much, such as shell powder paint class, shellwork class, wampum category, shell fertilizer class Etc., but these purposes do not make shell be fully utilized.Still there is most shells to be abandoned everywhere even at present The rubbish eliminated completely is difficult to as each coastal city, shell is presented as the Nature gives mankind's valuable source, and in China, The especially southeastern coastal areas can all generate a large amount of shell every year, and this aspect polluted environment, cause the soil of stockpiling Waste, is on the other hand not carried out waste utilization, wastes potential resource.Therefore, for the comprehensive utilization of shell, not only one Aspect can consume a large amount of shell, to protect environment, on the other hand can turn waste into wealth, realize its deep processing and utilization.

Summary of the invention

In view of the above-mentioned problems, saving raw material the object of the present invention is to provide a kind of shell utilization rate height, improving shell product The production method of the conch meal of added value is not only to add a kind of Novel environment-friendlymaterial material in building materials type again in building material industry Utilization rate even more is improved for shell and added value is by that by the powder being process, can answer the shell of various shells In various chemical products such as coating, there is certain absorption and sterilizing function.

A kind of production method of conch meal of the present invention includes the following steps:

(1), biodegradable: the shell degradation biological bacterium bred and shell are mixed, place 180 days or more, Shellfish meat remaining on shell, organic matter, cutin etc. are decomposed.

(2), shell cleans: the shell or shell waste material degraded being packed into screening machine and first carry out coarse fraction, is put clear It washes in equipment and is stirred, the soil, sandstone, cleaning of shell surface are removed, then adsorbed metal impurities with strong magnets It removes, then is rinsed well with clear water；

(3), shell is broken: the shell after removal of impurities is packed into degraded pond, is put into the pond that water is mixed with dietary alkali, It pulls out and after impregnating 1~2 day, place 1~2 day；It is subsequently poured into blender to be stirred, be rinsed after stirring with clear water, It dries, the cuticula of shell surface can be removed；

(4), the first time calcining of shell: calcining is 550-580 DEG C, calcination time 0.5-1h for the first time, and calcination atmosphere is Inert atmosphere.The water content being crushed is carried out to sterilization, disinfection and the drying of low temperature in the shell of 15%-20%, finished product Water content≤0.1% is qualification.

(5), selection by winnowing sieve: fine-grained shell will be ground into and be put into blower generating device, using wind energy to shell into The secondary removal of impurities of row and product screening.Ensure that product impurity is low, specification is complete.

(6), second of calcining of shell: second of calcining is 1250-1300 DEG C, calcination time 2-3h, the atmosphere of calcining For oxygen atmosphere.This calcining is thoroughly to be calcined the shell after first time calcining completion and selection by winnowing screening, moulds shell Powder microscopic aperture structure, and have and actively emit mid and far infrared line and enhance product performance.

(7), the hydration process of shell: the water of shell and corresponding proportion that second has been calcined is reacted, and anti- At once batch recycling is carried out using high-accuracy powder collector, the powder being collected is a kind of porous material, and particle size is in 15- Between 30um, aperture between 10-20nm, can effectively adsorb hydrone in air and

Grinding shells: it to keep this material more stable in use, just needs to carry out a powder and is crushed, to guarantee shellfish The indexs such as purity, whiteness and the content of beary metal of shell can be used range in, grinding method cannot use roll or squeeze work The flour mill of principle is ground, and needs to be ground with shearing, the mode of impact or selection airflow milling.Ensure shell with this The national standards such as powder and small, time of contact short purity, whiteness and the content of beary metal for improving shell of equipment contact surface are in usable range It is interior.

(8), ozone treatment: using ozone generating-device by the conch meal pulverized uniformly, at the uniform velocity enter ozone Ozone reaction is carried out in generation machine.It is using the ozone oxidation superpower to biological bacteria, organic matter remaining in conch meal is thorough Bottom digestion, entire reaction process duration 1-2h.

(9), it packs: the good conch meal of final process is packaged into bag.

The present invention has the advantage that

The conch meal of conch meal this method production of this method production is with free from extraneous odour, whiteness height, mesh number height and has spy Different hole configurations, can reach moisture absorption damping, and decomposing formaldehyde improves the effect of product hardness.

The present invention can be described in more detail in following embodiment, but the invention is not limited in any way.

Embodiment 1:(1), shell removal of impurities: shell and shell waste material are put in blender and are stirred, shell surface Soil, sandstone, metal impurities remove, then are rinsed well with clear water；

(2), shell is allowanced for bark: the shell after removal of impurities being packed into iron frame, is put into the pond that water is mixed with dietary alkali, is impregnated It pulls out and after 1 day, place 1 day；It is subsequently poured into blender to be stirred, be rinsed after stirring with clear water, dried, can be removed Remove the cuticula of shell surface；

(4), it is milled: fine-grained shell will be ground into pours into refiner and grind, 300~600 purposes are made Fine powder；

Embodiment 2:(1), shell removal of impurities: shell and shell waste material are put in blender and are stirred, shell surface Soil, sandstone, metal impurities remove, then are rinsed well with clear water；

(2), shell is allowanced for bark: the shell after removal of impurities being packed into iron frame, is put into the pond that water is mixed with dietary alkali, is impregnated It pulls out and after 2 days, place 2 days；It is subsequently poured into blender to be stirred, be rinsed after stirring with clear water, dried, can be removed Remove the cuticula of shell surface；
