At present, PVC is widely used in domestic and foreign disposable syringe. It has the advantages of excellent comprehensive physical and mechanical properties, low price and simple production technology. However, PVC as a disposable medical device has the following disadvantages:

1. There may be a small amount of polyethylene monomer in PVC, which has been proved to be carcinogen; Plasticizers that must be used in processing may gradually migrate out of the contaminated solution during the use process; Adding a variety of metal compounds as stabilizers may enter the human body to harm health; In order to improve the stability of metal stabilizer, the added phosphorus auxiliary agent further increased the toxicity of PVC; The waste PVC is difficult to deal with, which will cause serious pollution to the environment.

2. due to the above defects in PVC materials, some developed countries in the United States, Japan and Europe are developing alternative PVC materials. So far, PVC still dominates the disposable syringe market because of the lack of substitute materials which can compete with PVC in comprehensive performance and price.

Disposable syringes and other medical supplies that meet the production standards of medical devices have been strictly sterilized and sterilized before and when the products are packed. It can be said that they are completely sterile. Therefore, when unpacking and using the packaging, it is unnecessary to re disinfect them. Otherwise, it will cause pollution because "self disinfection treatment" is not strict and comprehensive by the manufacturer, The effect is "counterproductive".

Installation of Rigid Vinyl Tile

Rigid vinyl tile in the bathroom is an important decorative material for walls and floors in bathroom decoration, which occupies a very important position. Good rigid vinyl tile decoration out of the effect will be different, the service life will be longer; if the rigid vinyl tile in the installation of problems, then the quality of the entire bathroom will also decline. Today, we will introduce the installation method of rigid vinyl tile in the bathroom.

If the ceramic tile does not soak in water, it will snatch away the moisture in the cement mortar, reduce its strength, and reduce the adhesion between the ceramic tile and the wall, and the tile hollowing and falling off is easy to appear after a long time.

When paving, pay attention to the gap of ceramic tile and the compactness of cement mortar to reach a certain standard.

It is normal that the hollowing rate of ceramic tile accounts for less than 5% of the whole wall tile surface.

Pay attention to choose high-quality rigid vinyl tile when purchasing, which is the premise to ensure the quality of tile paving. In the construction process, the construction personnel may propose that the wall flatness error is large, and some measures need to be taken to supplement and level the wall separately. If some scattered expenses need to be added, the consumers should give support and cooperation as much as possible according to the situation.

The so-called ceramic tile draught is to put the ceramic tile in clear water to soak in advance for a period of time, generally, in about 2 hours, the actual operation can be based on the density of ceramic tile, the specific situation of the specific analysis.

Before laying rigid vinyl tile, it is also necessary to pay attention to the sufficient immersion of the tiles, so that the tiles can completely eat enough moisture, so as to avoid the hollowing and falling off of the tiles.

The traditional tile paving method is to use cement mortar for paving.

First of all, the proportion of cement mortar should be reasonable, and the volume ratio between them is 1:1. If in this case, the ceramic tile is still empty more, in addition to the workers in the process of paving technology is not high, the main reason is that the ceramic tile draft is not enough.

This is to ensure that the moisture in the cement mortar will not be snatched away by the tile after the rigid vinyl tile is pasted on the wall, so as to achieve its maximum strength, so as to prevent the tile from hollowing and falling off, which is the main reason for the ceramic tile to soak in water.

Store the Strawberries in the cold storage

Strawberries have high nutritional value, are rich in a variety of nutrients, and have health benefits. The market time of strawberries is generally from February to May. Because strawberries are relatively easy to rot, we should pay more attention to details during storage. , Need to be picked out in time to avoid bacterial proliferation. 1. Strawberry cold storage The temperature of the strawberry cold storage should not be lower than -3 ℃. Too low a temperature can easily cause strawberry frostbite and can only be stored for three to four days. Days or so. 2. Strawberry modified atmosphere cold storage It is recommended to store strawberries in an atmosphere-controlled warehouse. The temperature of the cold storage is recommended to be around 0 ℃ ～ 0.5 ℃, and the humidity should be controlled around 85% ～ 95%.

Strawberries have a high tolerance to carbon dioxide, so the use of modified atmosphere storage to keep fresh strawberries can control the concentration of carbon dioxide in the cold storage at 15% to 20%, but the concentration should not exceed 25%; the oxygen concentration is 3% to 5% . 1. Soak the strawberries in 0.3% peroxyacetic acid, add 50 mg / kg gibberellin to the cooling mixture for 1 minute, then dry the strawberries with cold air at 0 ℃ ～ 1 ℃; 2. Put the strawberry in a plastic food box or other container, wrap it with a polyethylene plastic bag with a thickness of 0.04mm, put an appropriate amount of sodium bisulfite and ethylene absorbent in the bag away from the fruit, and seal the bag mouth ; 3. Set up the environment in the modified atmosphere store, set the temperature of the cold store at about 0 ℃ ～ 0.5 ℃, the relative humidity is about 85% ～ 90%, and then put the strawberry storage container into the store.

Select suitable refrigerated door for cold room

The cold storage door, also known as the refrigerated door for cold room, is one of the important facilities of the cold storage, is also the passage for the cold storage to get in and out of the goods, and is one of the important parts for the cold storage to run cold. Because of the temperature difference between the inside and outside of the cold storage, when the door of the cold storage is opened, the hot air will have strong convection through the door opening, resulting in the exchange of hot and humid air into the warehouse, increasing the heat load of the cold storage. This part of the heat load is usually called the cooling capacity or cooling loss of the opening door. When opening the cold storage door, the hot air volume entering the cold storage is related to the height and width of the door, the temperature difference inside and outside the cold storage, and of course, the time and times of opening the door. For energy saving, the number of cold storage doors should be controlled as much as possible and the size of the door opening should be reduced as much as possible.

cold room maintenance

Sterilization of cold storage. The cooking materials and food in cold storage contain certain fat, protein, and starch. The presence of This nutrient of fungi and bacteria will make a lot of reproduction and growth. To do a good job in cold area sanitation management and ensure the cold storage quality of food and cooking materials, it is necessary to carry out regular cold area sanitation and disinfection work. Besides, acid disinfectants can be used for cold storage. The bactericidal effect of acid disinfectants is mainly to coagulate the protein in bacteria. Common disinfectants include lactic acid, peracetic acid, bleaching powder, formalin, etc. The specific method is: after the fish comes out of the cold storage, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below 50 degrees Celsius, then use the 50~100 grams of vinegar for each cubic meter volume of the cold storage warehouse, spray it into the storehouse with a sprayer, close the storeroom door first, and intermittently start the blower, so that the vinegar evaporates and flows in the storehouse so that the vinegar can absorb a lot of fish smell.

Cold storage manufacturer

Since the end of the 19th century, cold storage has been an important part of the logistics industry. Cold storage is mainly used for constant temperature and humidity storage of semi-finished products and finished products such as food, dairy products, meat, aquatic products, poultry, fruits and vegetables, drinks, flowers and plants, green plants, tea, drugs, chemical raw materials, electronic instruments and instruments, tobacco, alcoholic drinks, etc. Cold storage belongs to a kind of refrigeration equipment. Compared with refrigerators, it has a large refrigeration area, but they share the same refrigeration principle. Generally, refrigerators are mostly cooled by refrigeration mechanism. Liquid (ammonia or Freon) with very low gasification temperature is used as a coolant to evaporate under the condition of low pressure and mechanical control, to absorb the heat in the storage, to achieve the purpose of cooling. The most commonly used is a compression refrigerator, which is mainly composed of compressor, condenser, throttle valve, and evaporation pipe. According to the way of the evaporation tube device, it can be divided into direct cooling and indirect cooling. The evaporation pipe is installed in the refrigerated warehouse for direct cooling. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down. Indirect cooling is that the air in the warehouse is drawn into the air cooling device by the blower. After the air is absorbed by the evaporation pipe in the cooling device, it is sent to the warehouse for cooling. The advantages of air cooling mode are rapid cooling, uniform temperature in the warehouse, and the harmful gases such as carbon dioxide produced in the storage process can be taken out of the warehouse.
