The environment-friendly film removing liquid is prepared from the following raw materials in percentage by weight: 2-4% of basic hydroxide, 3-5% of diethylene glycol monobutyl ether, 3.5-5.5% of tetrahydrofurfuryl alcohol, 2-4% of ethylene glycol hexyl ether, 3-5% of an accelerating agent, 4-6% of a stabilizer and the balance of water. The stabilizer is prepared from hydroxypropyl chitosan, N-tri (hydroxymethyl) methylglycine, quaternary ammonium salt and water. The environment-friendly film removing liquid is suitable for a high-precision PCB processing technology, has good environmental protection performance and dry film removing efficiency, and meanwhile reduces corrosion to circuit patterns of a PCB.

Portable split camera lens

According to the technical scheme, the portable and detachable camera lens is characterized in that the portable and detachable camera lens comprises an upper shell, a lower shell is arranged on the bottom face of the upper shell, and a lens cover is arranged on the top face of the upper shell; during use, an inner column can retract into a side groove by pressing a rubber block, at the moment, a first thread can rapidly stretch to drive a connecting ring to be exposed, at the moment, the connecting ring can be limited through a bottom groove and a limiting ring, and a worker can connect the first thread with a second thread to enable the connecting ring to be exposed; the purpose of installing or detaching the upper shell and the lower shell through the connecting ring can be achieved, the connecting ring can be limited to prevent deviation through sleeving of a clamping block and a clamping hole, on the contrary, a shifting block can be moved downwards to drive a limiting ring and the connecting ring to move downwards, at the moment, a third spring is released to push sleeving of a rubber block and an inner hole, and the upper shell and the lower shell are detached; and a third spring is used for pushing the inner ring to be attached to the connecting ring, meshing between a first thread and a second thread is increased, and loosening is prevented.
