Packaging, transportation and storage:

*Bubble film is used for small crucibles, and straw is tightly packed for large crucibles, so that the crucible is not exposed

*Strictly prevent shock, moisture and moisture during transportation

*The product should be placed in the warehouse. If it is stored in the open air, the bottom of the shelf should be padded and covered with a waterproof cloth.

the

Precautions:

*It is easy to oxidize when used in a high temperature and strong oxidizing atmosphere. Therefore, strong oxidizing atmosphere should be avoided when providing different pyrogens, otherwise the use function will be reduced.

*The crucible is easy to absorb moisture, so it is strictly forbidden to get wet during storage, otherwise it will burst when the furnace is preheated. If it is damp, it should be dried gradually before going out of the furnace, and the temperature should not exceed 500°C.

*The crucible is a fragile product, avoid dropping, touching, toning, dragging, rolling and prying with hard objects during handling to avoid cracks

*Check the crucible for cracks, gaps and other defects before leaving the furnace

*Do not stuff too tightly when feeding, and do not leave a cold bottom, so as not to expand after heating, and the crucible will burst.
