s2: washing the mould, namely washing the mould of the medical latex glove;
s3: soaking the ceramic mould in calcium water;
s4: drying the mould, namely drying the mould soaked with calcium water;
s5: soaking latex, namely soaking the dried mould in latex solution of the medical latex glove to enable the surface of the ceramic mould to be covered with a layer of latex to form the latex glove;
s6: crimping, namely crimping the opening of the latex glove formed on the die in the step S5 by a crimping device;
s7: drying the gloves, namely drying the curled medical latex gloves, and removing water on the surfaces of the medical latex gloves;
s8: leaching, namely soaking the dried latex gloves in hot water and taking out;
s9: drying and vulcanizing;
s10: water cooling, namely soaking the latex gloves obtained in the step S9 in cold water for cooling;
s11: and (4) demolding, namely taking the latex gloves off the ceramic mold, and then packaging to finish the production of the medical latex gloves.
6. The method for manufacturing medical latex gloves with strong elasticity and breakage resistance according to claim 1, wherein the raw material preparation in the step S1 is that nitrile rubber and natural rubber are put into a melting device to be melted and refined, so that the two rubbers are compatible, then dispersant, thickener, emulsifier, defoamer, toughening agent and coloring agent are added, the coloring agent can be selected according to requirements to prepare latex, and continuous heat supply to the latex is kept in the production process of the latex gloves, so as to prevent the latex from being solidified.
7. The method for manufacturing medical latex gloves with strong elasticity and breakage resistance as claimed in claim 1, wherein the mold material in step S2 is ceramic, the cleaning process is performed sequentially through a soap water tank, a clean water tank, a bleaching agent tank and a clean water tank, and four rows of rotating disk brushes are arranged on the clean water tank to clean the two rows of ceramic molds, the disk brushes can clean up the stains between the finger joints of the ceramic hands, and the next operation is performed.
8. The method as claimed in claim 1, wherein the step of S5 is preceded by inserting the ceramic hand mold into a wetting agent to prevent the latex glove from sticking to the ceramic hand mold, so as to facilitate the mold release, and the latex glove is not torn during the mold release, thereby causing defects.
9. The method as claimed in claim 1, wherein the drying and vulcanizing temperature in the step S9 is 150 ℃ and 200 ℃, and the pressure is controlled to be 5-15 MPa.
10. The method of claim 1, wherein the latex glove is continuously rotated at a constant speed of 80-120 rpm during the leaching process to remove the excess latex from the surface of the latex glove and maintain the smoothness of the surface of the latex glove.
