Highly wearable, highly heat effective non-stick pan and its making process

Abstract

A stick free frying pan with a highly antifriction highly thermo efficiency and manufacturing technique thereof is disclosed, which belongs to the household cooking utensil field. It comprises a pot body and a stick free layer installed inside the inner surface of the pot body. It is characterized in that the pot are designed to be a bi-part type structure of the pot wall(1) and pot bottom(3), and being rivet welded, melt welded and braze welded into a hybrid type pot body through dead joint member. Conduct supersonic speed electric arc spay coating uneven fine micro particle layer after the surface coarsening of the pot body and before the spray coating of the stick free layer. Compared with the prior arts, it has advantages of high efficiency, firm combination between the pot bottom and pot wall, high antifriction and long service life of the anti stick life and can fry the dish directly by stainless metal turner.

Description

technical field [0001] The invention discloses a non-stick frying pan with high wear resistance and high thermal efficiency and a manufacturing process thereof, belonging to the field of household cooking utensils or electric cooking utensils. Background technique [0002] There are many kinds of existing non-stick pans, but they are mainly ordinary and electric heating pans. Ordinary non-stick pans are mainly sprayed with polytetrafluoroethylene (PTFE) directly in the body of aluminum, iron or stainless steel non-stick pans. High-temperature sintering; electric heating pots are mainly made by spraying polytetrafluoroethylene (PTFE) directly on the body of ordinary aluminum, iron or stainless steel pots, and sintering at high temperatures. Electric heating tubes or electric heating devices are welded outside the bottom of the pot. Both types of non-stick frying pans are non-stick and easy to clean, bringing convenience to people's lives. But because the polytetrafluoroethyl...

Problems solved by technology

However, due to the nature of the sprayed polytetrafluoroethylene (PTFE) non-stick layer material itself, it is afraid of scratching and not wear-resistant, so only a wooden shovel can be used, and the wooden shovel brings a lot of inconvenience to the user.

In addition, although pure iron pans are beneficial to human health, they are prone to rust and are relatively bulky; pure aluminum pans conduct heat quickly, but dissipate heat quickly, and long-term use is not good for human health; pure stainless steel pans are light in weight, beautiful, and do not rust , is a product that people generally welcome in recent years, but compared with aluminum pans, the heat transfer is slow, and it is easy to stick to the bottom of the pan when cooking. And stainless steel double-bottom electric frying pan, an aluminum soaking plate is welded outside the bottom of the stainless steel pot body, which better solves the problem of slow heat transfer of stainless steel pots and easy sticking to the bottom of the pot when cooking, but because the bottom of the pot is spherical, As a result, the welding qualification rate is low, the welding is not strong, and the thermal expansion coefficients of the two materials are different, and it is easy to crack during use. At the same time, the bottom of the stainless steel pot on the aluminum soaking plate is slow in heat conduction, which hinders the transfer of heat, so its thermal efficiency is low.
