Drop hydrogen peroxide on the blood.
Pay attention to shading when treating blood stains with hydrogen peroxide, because strong sunlight will promote the decomposition of hydrogen peroxide into water.
Step 2 use enzyme washing powder
A large number of enzyme preparations were added to the enzyme-added washing powder. Protein structure in blood and dirt can be destroyed, and protein can be decomposed into soluble peptide bonds. Attention should be paid to the use of enzyme-added washing powder, and the water temperature should be 40℃, and the highest temperature should not exceed 50℃, otherwise the enzyme in washing powder will be killed and the decontamination ability of washing powder will be reduced.
Use white vinegar
Soak the bloodstained place in white vinegar for about ten minutes, and then wash it twice with clear water, which can effectively remove the bloodstains.
Use ginger
You can scrub the blood with ginger first and then with cold water, or you can clean it.
How long does it take to wax the resin?
Everyone's weight, height, sex and other factors are different, so there is no specific time limit for waxing the body. Currently about
The record of the formation time of corpse wax was summarized by statistical method. For example, it takes 3-4 months for adults to wax local corpses, and it takes 1- 1.5 years for adults to wax whole bodies. Fat corpses are more likely to form corpse wax.
Case: 1. The corpse is female, obese and fatty, and it is easy to form a corpse and wax it.
2. Special environmental factors of wetlands. Although the time from disappearance to the discovery of the body happened to go through the whole summer, first of all, in the wetland environment,
The average temperature of 17-25℃ is lower than the favorable temperature for bacterial reproduction (25-35℃), so the bacterial reproduction is not vigorous, which slows down the corruption of the corpse; Secondly, the average temperature is about 17-25℃ and the average relative humidity is 77%, which is beneficial to the decomposition of adipose tissue into fatty acids and the formation of corpse wax.
3. The corpse was found in the grass, so the ventilation around the corpse was poor and the air mobility was low, which delayed the decay process of the corpse.
When food poisoning occurs, it can be alleviated by grinding mung beans and washing them.
Toxicity.
When salt is mixed with acidic detergent, it will produce toxic gas.
The skin of the deceased was pink, and some spots appeared from the inside out, which was obviously caused by sodium hydroxide (Na0H) poisoning:
If the poison is in the capsule. It takes at least 15 minutes to show toxicity.
It is best to gargle with something containing protein, such as milk.
Potassium cyanide is insoluble in cold water.
The surgeon will leave a deep and obvious mark on his index finger, which is caused by frequent dressing.
