As we all know, acid-resistant latex protective gloves are mainly used to protect the hand contact with acids, alkalis or need to enter the acid, alkali liquid work caused by injury. Such gloves can also be worn during general operation in the forestry, agriculture, animal husbandry and fishing industries. Cantonese dragon acid-resistant latex gloves comply with LD34.2-1992 standards.

Next to tell you about the labor protection industry acid-base-resistant protective gloves are mainly divided into what categories and acid-alkali-resistant latex protective gloves technical indicators:

 First, acid-base-resistant protective gloves are mainly divided into what categories:

 1, rubber acid-resistant and alkali-resistant gloves: such gloves have two kinds of finger and finger.

 2, latex industrial gloves:

      Such gloves are worn in contact with low concentrations of acid-base solutions, printing and dyeing fluids, contaminants, general chemicals, toxic chemical raw materials and general industrial operations to prevent occupational skin diseases, soft texture and multiple product specifications.

3, immersion of acid-alkali-resistant gloves: the product type of such gloves is hand-shaped gloves.

4, plastic gloves: such gloves, acid and alkali resistance, cold resistance, anti-aging.

Second, acid-alkali latex protective gloves technical indicators are:

   1, acid-base-resistant protective gloves should not have brittle, sticky, broken and frost and other defects.

   2, gloves should have airtry performance, under the pressure of 10 to 1kpa, can not appear gas leakage phenomenon.

   3, gloves should have a strong anti-penetration capability:

      (1) Latex gloves permeability test film requirements are as follows:

      Cut 100mm x 100mm test pieces on the palms, backs and sleeves of the gloves, take 3 pieces, a total of 9 pieces. Place the test piece on the glass tube (the glass tube is filled with 40 sulfuric acid or 40 sodium hydroxide solution, with colors such as meth blue or crystalline purple to color the solution), and then place the glass tube on a glass plate with filter paper. Keep the test piece in contact with the solution at 30min. Check that the filter paper should not be dyed, the test sheet washed dry surface without cracking, dissolution, peeling and other anomalies.

      After passing the above test, the test piece is stretched. At the stretch force of 4.9N (including the self-weight of the fixture below), maintain 10min and the test plates should be tested for cracks, breakages and other anomalies.

      After passing the first test mentioned above, the above test is repeated, but the test film and solution contact hold time is reduced to 15min, after examination should be no abnormal phenomenon.

      (2) Latex gloves finished product permeability requirements. Impregnate the latex or rubber finished gloves in a solution of 40 sulphuric acid or 40 sodium hydroxide (impregnated to the wrist) for 30min, then hang the gloves for 24 hours for natural drying without wiping off the attached solution. Repeat the above test three times.

      After the above-mentioned test of the finished gloves worn on the hand, 30 grip and relaxation movements, visual inspection of the various parts should be free of obvious expansion, hardening, contraction and other abnormal phenomena. Only through the test and finished product test meet the requirements, can be judged to be permeable qualified.

      (3) The permeability requirements of acid-base-resistant plastic gloves. The test pieces and finished products shall pass the test at a concentration of 40 sulphuric acid or 30 sodium hydroxide solutions in the same way as the latex and rubber gloves.

(The above acid-resistant and alkali-resistant glove test method should be tested in the same training of professional testers or let professional experimenters experiment)
