Abstract
The invention discloses a rust removal method for a guide wheel for a solar crystalline silicon slicer. The rust removal method for the guide wheel for the solar crystalline silicon slicer comprises the following steps of: a, shielding a non-coated area of the guide wheel of which the surface has rusty spots; b, putting the shielded guide wheel in a sand-blasting machine; c, starting the sand-blasting machine to perform sand blasting on the exposed surface of the guide wheel for 10-15 minutes; d, taking out the guide wheel after the sand blasting is ended, checking a rust removal effect, and repeating the steps b and c if the surface of the guide wheel still has rusty spots; e, performing surface cleaning on the guide wheel of which the surface rusty spots are completely removed; and f, coating the guide wheel of which the surface is cleaned. The rust removal method for the guide wheel for the solar crystalline silicon slicer has the beneficial effects that rust removal is performed by adopting a sand blasting process, and therefore, the labor strength of a worker is reduced, meanwhile, a rust removal effect is remarkable, the surface roughness of the guide wheel is even, a binding force of the guide wheel and a coating layer is enhanced, and the coating quality is improved. The rust removal method for the guide wheel for the solar crystalline silicon slicer has obvious economic benefits.
Description
Technical field
This invention relates to a kind of method of rust cleaning, and particularly a kind of solar energy crystalline silicon slicer belongs to photovoltaic product manufacturing technology field with the derusting method of guide wheel.
Background technology
Solar electrical energy generation receives much concern owing to advantages such as having cleaning, safety and wide material sources, becomes the first-selected approach that solves global energy crisis and amblent air temperature variation.The solar photovoltaic industry has become the industry of a lot of state key support development.World's photovoltaic output entered rapid growth since 2003.
Crystal silicon solar batteries is the main product in market, and preparation need be cast HIGH-PURITY SILICON silicon ingot or be drawn into silicon single crystal rod during solar cell, and evolution becomes brilliant brick then, to brilliant brick mill, chamfering, just cut into the silicon chip that is used to make solar cell afterwards.The silicon chip of main flow cutting at present is multi-thread cutting technique, adopt special-purpose slicer, and guide wheel is one of core component of the type equipment.After guide pulley surface has applied macromolecular material,, be installed in then on the slicer the operation of cutting into slices of silicon wafer brick again through fluting.For the metal guide wheel, the surface can produce rust staining repeatedly using later, can influence the coating quality of top layer macromolecular material.Traditional derusting process is to adopt sand paper or emery wheel to be polished in the rust staining position, shortcoming is that lost labor and effect are bad, causes guide pulley surface roughness skewness, even causes serious coating quality problem, and then the percent defective rising that causes cutting into slices, increased the silicon chip manufacturing cost.
Summary of the invention
The purpose of this invention is to provide the derusting method of a kind of solar energy crystalline silicon slicer with guide wheel, adopt this method not only can remove the iron rust of iron core guide pulley surface effectively, in high quality, and, improved the quality that follow-up macromolecule applies, thereby improved chipping qualities, reduced the manufacturing cost of silicon chip.
Technical scheme: a kind of solar energy crystalline silicon slicer derusting method of guide wheel may further comprise the steps:
A) surface there is the non-coating zone of the guide wheel of rust staining do and blocks processing;
B) will put into sand-blasting machine through the guide wheel that blocks processing;
C) start sand-blasting machine the guide wheel exposed surface is carried out blasting treatment, the processing time is 10-15 minute;
D) after blasting treatment is finished, guide wheel is taken out, check the rust cleaning effect, repeating step b, c if guide pulley surface still has rust staining;
E) guide wheel that will remove surface rusty stain fully carries out the removing surface processing;
F) will carry out coating processing through the guide wheel that removing surface is handled.
According to the size and the material of guide wheel, carry out the medium of blasting treatment among the described step c and can select little steel ball or aluminium oxide for use.The order number of described aluminium oxide is 24-46#.
Beneficial effect: the present invention adopts blasting craft to eliminate rust, and has reduced labor strength, and the effect that eliminates rust simultaneously is remarkable, and the guide pulley surface roughness is even, and has strengthened the adhesion of guide wheel and coat, has improved coating quality, has tangible economic benefit.
