The invention discloses a carbon crystal heating wall heating product and a production process thereof. The carbon crystal heating wall heating product comprises a carbon crystal heating plate, a reflecting heat insulation plate and a fixing frame. The carbon crystal heating plate comprises a surface protecting layer, a decorating layer, a connecting layer, a heating layer, an insulation layer, a carbon crystal heating film, a first conductive copper bar and a second conductive copper bar. The reflecting heat insulation plate comprises an upper reflecting layer, a heat insulation layer and a lower reflecting layer. The first conductive copper bar and the second conductive copper bar are fixed at two ends on the same side of the heating layer. The carbon crystal heating film is printed on one side of the heating layer where the conductive copper bars are fixed through a silk-screen printing method, and two ends of the heating film are in contact with the first conductive copper bar and the second conductive copper bar. The surface protecting layer, the decorating layer, the connecting layer and the insulation layer are sequentially connected and fixed. The carbon crystal heating plate and the reflecting heat insulation plate are connected and fixed through the fixing frame. The carbon crystal heating wall heating product has the advantages of being long in service life, not easy to age, not prone to be yellow, high in heating efficiency and the like. A protruding process is environmentally friendly, high in efficiency and strict in quality control.

The invention discloses an ultra-low VOC polypropylene material and a preparation process thereof. The material is composed of the following raw materials in parts by weight: 60-65 parts of polypropylene, 10-15 parts of toughening agent, 20-25 parts of talcum powder, antioxidant 0.5-0.8 parts of light stabilizer, 0.3-0.5 parts of light stabilizer, 2-4 parts of anti-scratch agent, 0.2-0.4 parts of lubricant, 1-3 parts of toner; the preparation process introduces supercritical fluid as a reaction carrier, through Its strong penetrating and dissolving ability can absorb volatile small molecules in the fluid. At the same time, the domestic raw material formula system is adopted to replace the currently widely used imported raw material formula system. On the premise of ensuring the material odor and VOC performance, the cost can be reduced and the competitiveness of the product can be improved. Exhaust through the vacuum exhaust port. It is non-toxic and harmless, has no pollution to the environment, and has great promotion potential.

The invention relates to the technical field of ketone-benzene dewaxing, in particular to a preparation method of white oil. The preparation method includes the following steps: 1) dewaxing: mixing the low-wax raw material with the first ketonebenzene dewaxing solvent, filtering and separating to obtain the dewaxing filtrate and the oily waxy liquid; 2) one-stage deoiling: mixing the oily waxy liquid with the first The diketobenzene dewaxing solvent is mixed and divided into the first oil-containing wax liquid and the second oil-containing wax liquid; 3) Second-stage deoiling: mix the first-stage deoiled wax liquid, the second oil-containing wax liquid and the third ketone-benzene dewaxing solvent After that, it is divided into the third oil-containing wax liquid and the fourth oil-containing wax liquid, and the third oil-containing wax liquid is filtered and separated to obtain the second-stage deoiling filtrate and the second-stage oil-containing wax liquid; 4) clay refining. In the preparation method of the present invention, the low-wax raw material is dewaxed by ketone benzene to ensure the low-temperature fluidity of the product, and the low-wax raw material can be processed. The process is stable and the dewaxed oil with a qualified freezing point is obtained, and the product stability, impurities and color are guaranteed by refining with white clay. , by increasing the amount of stripping steam to ensure the smell of the product.

The invention provides a method for improving abnormal smell absorption by filter paper of an air filter and relates to the technical field of filter processing. The surface wall of the filter paper is made rough, and after soaking through deodorant liquid and drying processing, smell removing powder is added, and high temperature setting is performed, so that the abnormal smell absorption is improved. The method has the advantages that the process is simple; by soaking existing filter paper through the deodorant liquid and adding the smell removing powder, it is guaranteed that abnormal smell in the air undergoes absorption treatment when the filter paper is used, and it is guaranteed that the filtered air not only has no dust, but also has no smell.

The invention belongs to the technical field of food processing, and discloses a fresh-keeping method for peanuts. The method comprises: sterilizing fresh peanuts; The water content is ≤8%, and the water loss rate of peanut kernels is ≤5%. The peanuts are stored in an environment with a humidity of ≥85% and a temperature of 3-8°C. The method of the present invention does not need to use food preservatives to carry out antiseptic treatment of peanuts, not only can avoid the toxicity hazards of chemical preservatives, is beneficial to human health and environmental protection, but also can effectively retain the hue, taste and nutritional components of peanuts themselves, It solves the inconvenience and troubles brought by the traditional craft, solves a big problem for the traditional delicious boiled peanuts, meets the needs of consumers, and has broad market application prospects.
