How to use alkali to clear the sewer

Each of us should have a sewer in our home. This place is used for drainage, but it often has some problems, including the situation that the sewer is blocked. There are many ways to dredge the sewer, but most of them are troublesome. Alkali can also be used to dredge the sewer. So how to use alkali to dredge the sewer?

Put the alkali into the sewer mouth, and then pour a pot of boiling water into it. Not a thermos, but a large kettle for boiling water.

How to deal with accidental ingestion of alkali: After alkali enters the digestive tract, it combines with tissue protein to form gelatinous protein salt and saponifies fat, causing tissue dehydration. If you accidentally ingest alkali at home, drinking some vinegar can quickly neutralize the alkali. Drinking plenty of warm water will only dilute the alkali. Drinking an appropriate amount of egg white or animal oil can play a certain role in competitively inhibiting tissue protein binding and fat saponification. Therefore, once you accidentally ingest alkali, you should immediately drink an appropriate amount of vinegar, and then drink some egg white or animal oil. This is a relatively safe way to detoxify.

Correct treatment method:

a. Drink plenty of warm water.

b. Drink some egg white or animal oil.

c. Drink an appropriate amount of vinegar.

Those in serious condition should be sent to hospital for treatment promptly.

The harm of using pyroalkali in fresh food to the human body: If the food is edible grade pyroalkali, the harm to the human body depends on the amount ingested. A small amount will basically have no harm, but a large amount will burn the digestive tract and damage the digestive tract mucosa. If it is industrial pyroalkali, it is more harmful to the human body because it contains heavy metals.

Whether these fresh foods contain alkali can be detected by direct testing of sodium hydroxide. There is no standard method for industrial alkali, but it can be found in GB5175-2008 "Food Additives".

"Sodium Hydroxide" has strict regulations on the food additive sodium hydroxide, and has strict limit requirements on the impurities and heavy metals it contains. In other words, if you want to know whether it is industrial grade or edible grade, you can check the heavy metal content in it according to national testing standards, and use this indicator to determine whether the food meets the corresponding hygiene standards.
