Problems solved by technology

[0002] Because the company currently has many SECC and SGCC materials without surface treatment, there is rust on the cut surface, and every time it needs to be repainted or painted with silver paint, it is a waste of man-hours, and it is prone to dead ends, which cannot guarantee the quality. In addition, if the galvanized sheet and Hot-dip galvanized sheet processing, the surface corrosion resistance of the workpiece is poor, and the effect is not ideal
Merchants will have certain requirements in terms of corrosion resistance, brightness, softness, etc. when choosing plated parts. In these aspects, the traditional process methods can no longer meet the current requirements for products. Therefore, this section is specially tested. Anti-rust new technology

Embodiment 1

[0016] Embodiment 1, a rust-proof sealing process for a workpiece, step 1, cutting the workpiece at room temperature to form a cut surface. The workpiece is washed with water in an environment with a pH value of 8, and then placed in the same environment for secondary washing to remove impurities and dust on the workpiece to obtain a spare workpiece; step 2, at normal temperature, according to the bath liquid and rust prevention The proportion of sealing agent is to add 40 kg of anti-rust sealing agent to every 1000L bath liquid to prepare the bath liquid, and the total alkalinity is controlled at 22pt for standby. Contact the cut surface of the spare workpiece with the bath solution, and clean it for 10 minutes; step 3, put the spare workpiece treated with the anti-rust sealant into the environment with a temperature of 40 ° C and a pH value of 8 for water washing, and then put it in Wash with pure water in an environment with a pH of 7.

Embodiment 2

[0020] Embodiment 2, a rust-proof sealing process for a workpiece, step 1, cutting the workpiece at normal temperature to form a cut surface. The workpiece is washed in an environment with a pH value of 12, and then placed in the same environment for secondary washing to remove impurities and dust on the workpiece to obtain a spare workpiece; step 2, at normal temperature, according to the bath and rust prevention The proportion of sealing agent is to add 60 kg of anti-rust sealing agent to every 1000L bath liquid to prepare the bath liquid, and the total alkalinity is controlled at 28pt, which is reserved. Contact the cut surface of the spare workpiece with the bath solution, and clean it for 20 minutes; step 3, put the spare workpiece treated with the anti-rust sealant into the environment with a temperature of 50 ° C and a pH value of 12 for washing, and then put it in Wash with pure water in an environment with a pH of 9.

Embodiment 3

[0021] Embodiment 3, a rust-proof sealing process for a workpiece, step 1, cutting the workpiece at normal temperature to form a cut surface. The workpiece is washed with water in an environment with a pH value of 10, and then placed in the same environment for secondary washing to remove impurities and dust on the workpiece to obtain a spare workpiece; step 2, at normal temperature, according to the bath liquid and rust prevention The proportion of sealing agent is to add 50 kg of anti-rust sealing agent to every 1000L bath liquid to prepare the bath liquid, and the total alkalinity is controlled at 24pt for standby. Contact the cut surface of the spare workpiece with the bath solution, and clean it for 15 minutes; Step 3, put the spare workpiece treated with the anti-rust sealant into the environment with a temperature of 45 ° C and a pH value of 10 for washing, and then put it in Wash with pure water in an environment with a pH value of 8.

Abstract

The invention relates to the field of electroplating technologies, in particular to an antirust sealing technology of a workpiece. The antirust sealing technology comprises the steps that 1, the surface of the workpiece is pretreated, that is the workpiece is subjected to water washing in a water environment with a pH value of 8-12, and then subjected to the water washing for the second time in the same environment to form a standby workpiece; 2, the surface of the workpiece is subjected to sealing treatment, that is the standby workpiece is put in tank liquor with an antirust sealing agent and soaked for 10-20min at a normal temperature; and 3, the standby workpiece treated by the antirust sealing agent is subjected to the water washing and then pure water washing. With the adoption of the antirust sealing technology, an antirust function is better; the antirust time is longer; the working efficiency is high; and the production cost is lowered.
