Natural spring mattress process - — Terra's production process

Natural spring mattress process - — ,

she production process will naturally spring hotel mattress, adding curing agent, gelling agent, antioxidant and so on all the necessary additives mixtures, fill into a mold. However, only partially filled with mold, filling quantity depends different spring block hardness requirements. This kind of mold is special aluminum mold, equipped with a large number of needles, each mold cover and mold chassis have approximately 20000 needles. This pin has a dual role, one is to help to heat transfer to the spring block center, because the foam rubber is not a good conductor of heat, at the same time helps to form a process after dry 'needle holes. Mould peripheral with rubber sealing ring, sealing ring hollow channel is in, can with ethylene glycol/water through the heat transfer fluid, etc. Liquid foam part filling mold, mold is closed, cooling and vacuum processing. Foam under the action of vacuum expansion, completely fills the mold, at this point, the internal supporting semi permeable paper gasket can be ruled out of the mold in the air, at the same time to prevent the liquid foam flow into the vacuum tube. Hotel mattress after cooling mould, make the bubble freeze to about 30 ℃, with a carbon dioxide gas through the frozen block body, make the bubbles' curing 'or' gel. At this time, a single bubble began to link to each other. Stay after gelation, heated to 110 ℃, the die keep several minutes. Heat can cause rubber adhesive 'hardening' or 'cure', the products normal resilience. Stripping, cleaning the product, remove residual soap, etc. , finally dry, test.
