Vet du? Det råa materialet från stekpannor är aluminium, och rå aluminium är mycket skadligt för människokroppen . Så kommer att äta rätter tillagade i aluminiumkrukor på att påverka hälsan? Hur görs en kvalificerad aluminiumstekpanna?
Huruvida aluminiumkrukor är skadliga för människokroppen beror främst på huruvida produktionen av aluminiumkrukor uppfyller kraven och den rimliga användningen av aluminiumkrukor .
In our daily use, the melting point of aluminum will not be reached. The aluminum that can be decomposed by using solid aluminum pots to cook will not reach the level of poisoning. In addition, frying pans are mainly used for frying food, and the scope of application is relatively narrow, so there is no need to worry about the use of frying pans. Det finns en mogen stekpanna produktionsprocess i många tillverkande fabriker för utländska köksredskap .
On this assembly line, the furnace temperature for melting aluminum blocks must reach 660 degrees Celsius or above. At the same time, because aluminum is harmful to the human body, workers cannot stay nearby for a long time. The molten aluminum will be scooped up by a computer-controlled spoon-shaped robotic arm and poured into the die-casting machine in Ett specifikt belopp för att trycka på botten av stekpannan .
The sudden drop in temperature will cause the aluminum to solidify quickly in the die-casting machine, and because of the push of the ejection mechanism, the solidified casting will be formed under high pressure, forming the prototype of a frying pan. The initially formed bottom of the pot is taken out by the robotic arm, put on the crawler for transportation, and delivered to the workers.
After getting the bottom of the pot, the workers will use iron bars to knock off the aluminum that overflowed when pressing the bottom of the pot, and then preliminarily grind the edge of the bottom of the pot to make it smoother and rounder. There is no need to worry about the large amount of scraps overflowing due to high pressure being wasted. They will be poured into the recycling hink och vänta med att komma in i ugnen för andra gången .
Nästa process är slipning och polering . Botten på potten som transporteras till monteringslinjen igen kommer att skickas till en speciell linje för detaljerad bearbetning . först, använd en bältesslipare för att ta bort stöten på den yttre ytan på potten, använd sedan ett kvarn för att slipa insidan, och äntligen borra en tråd på hålet på varje pol -potten i hela. Avslutad . Ett visst antal stekpannor skickas kollektivt till den bindningsvärmeplattan . Detta steg kan göra att stekpannor utan stick jämnt uppvärmda när de används senare .}}
Efter att ha gjort ovanstående kan botten på dessa stekpannor utan stick för beläggning .
Before each frying pan is placed in the coating workshop, the workers will conduct dust removal inspection to prevent large impurities from affecting the coating effect. After the inspection, they will rotate into the workshop one by one. This rotary spraying method can ensure that the coating is evenly attached to the surface of the pot. And in order to make the coating firmly fixed on the Krukkropp, dessa stekpannor kommer också att gå igenom en låga uppvärmningsprocess innan de går in i sprutningen .
The coating methods of different factories and workshops are not much different. However, due to the different levels of machine technology advancement, the coating equipment used by some factories can only coat one side at a time, so in this case, it is necessary to manually coat the outer surface of the frying pan on the reverse side. But in general, whether it is the inner layer or the outer surface, the coating methods are almost the same, Så jag kommer inte att gå in på detaljer här .
After the coating is completed, there is the last step of drying. In order to quickly dry a large number of frying pans, these cookware factories will be equipped with a large drying tunnel. The frying pans that have just completed the coating will move along the drying tunnel and will be completely dried at the end, which is very fast and convenient.
After the bottom of the pan cools down, the workers will polish the excess coating material and put it on the conveyor belt, and then enter the final handle installation link. After the workers install the handle, they will label the frying pan with product model and other information and pack it into boxes. Thousands of non-stick frying pans are ready to go on the market, waiting for the new owners to show their skills in their new hem .
Så kommer du att vara den nya ägaren till dessa stekpannor utan stick?
