Technological process of manufacturing rubber gloves

I. Description of the production process of latex rubber gloves:

Nguyên liệu chính của dây chuyền sản xuất là mủ cao su thiên nhiên (60%) được phối trộn với phụ gia hóa học để tạo bán thành phẩm. Bán thành phẩm sẽ được ủ một thời gian với nhiệt độ bình thường, sau đó hỗn hợp này được đổ vào dây chuyền sản xuất găng tay y tế và gia dụng. Găng tay cao su được đưa vào công đoạn sau lưu hóa. Sau đó sẽ qua công đoạn kiểm tra, đóng gói và tiệt trùng.

II. Process of making rubber gloves:

Form cleaning tanks -> Air conditioning form (oven) -> Dipping flocculation -> Drying flocculation (oven) -> Pus dipping -> Liquid dispersion (camming) -> Latex gel and setting (cabinet drying) -> Water filtration -> Ring rolling (granules) -> Final treatment (oven) -> Powder application (slurry) -> Drying (drying with mud or surrounding space) -> Process Gloves Stripping

III. Description of the manufacturing process of medical gloves:

1. Washing the mold: the porcelain mold is put into the mold washing process. The mold washing process is as follows: the mold is put into a water bath with a temperature of about 70oC. This tank has the effect of absorbing dirt on the mold to help remove dirt for easier cleaning. After dipping the mold in the water tank, the mold will be passed through the water spray to ensure the mold is clean and free from dirt affecting the following stages of the process.

2. Drying of the mold: Drying the mold after the mold passes through the hot water bath, the wet ceramic mold will be passed through the drying chamber to dry.

3. Dipping Curing: Next, the porcelain molds are dipped in a dipping bath containing calcium carbonate, calcium nitrate and wetting agent. These substances bind to latex and the glove thickness is determined by the concentration of the setting solution. This solution is also used to ensure gloves easily separate from the ceramic mold.

4. Freezing drying: the mold is continuously passed through the dryer to dry. This drying process is crucial for the next glove forming step.

5. Immersion of latex latex: porcelain molds are immersed in a Latex bath containing diluted latex with specified concentration. This latex solution is mixed with water, buffers, wetting agents and alkalis. The concentration of the solution in the setting bath, the speed of the chain and the concentration of the pus will determine the weight and length of the glove.

6. Pre-vulcanization drying: followed by the drying of gloves. The pre-adjustable temperature ensures that the gloves are partially dry, making the following steps such as de-alkalizing and contouring easier. If the gloves are not dry enough, they will come off when de-alkaline, resulting in poor edge folding.

7. Pass extraction tank 1 & 2 (specified temperature 50 degrees C – 70 degrees C), remove impurities, some impurities, proteins in rubber. This stage: after going through the drying stage, the gloves are transferred to the 1st washing stage. Here, the gloves are immersed in a tank with water at a temperature of about 70 ° C. Water will partially remove the protein from the glove. The elimination of protein is necessary as it avoids the user with a protein allergy. Gloves after going through the first wash step will be transferred to contouring and vulcanization.
8. Braiding: Using the broom to trim the rim, these brooms continuously rotate and roll over the top of the glove. Lacing is carried out until appropriate dimensions are obtained. The rim makes it easy for users to wear gloves.

9. Continuing through the vulcanization drying stage, starting the vulcanization process of rubber: the specified temperature ranges from 110 degrees C – 140 degrees C. Depending on the speed of conveying and the incubation time, keep the heat properly, the Thermal parameters for vulcanization are extremely important, as the temperature increases will increase the amount of fusion sulfur as well as significantly increase the curing rate. When the “under-vulcanization” or “over-vulcanization” will affect the mechanical properties of the product (especially the tensile strength and tensile strength), in addition to age reduced product life.

10. Pass the extraction tanks (the specified temperature is 60 degrees C – 90 degrees C)

11. Through the cornstarch tub, dipping the tub of flour prevents the finished product from sticking, as well as making it easier to wear gloves.

12. Through the last oven: Dry

13. Gloves stripping and glove removal process: At the end of the glove removal step, gloves are taken out of the mold. After the glove is finished, the porcelain molds go back to the cleaning process.
