Vacuum flask - — Cosmetic industry insulation every champion

On the market a lot of more and more big skin care products use vacuum bottle packaging, vacuum flask is a can make the gas container sealed off from the outside temperature or bacteria isolated from the external container, so what is the principle of the vacuum flask? Where it come from? Guangzhou cosmetics bottles manufacturers understand the vacuum flask together with you.

vacuum flask has the characteristic of thermal insulation bacteria isolation, modern thermos is British physicist James & middot; Dewar invented jazz in 1892. He was on a gas liquefaction research work, liquefied gas in low temperature, first of all need to design a can make the gas container sealed off from the outside temperature, so he please glass technician berger for him blowing a double deck glass container, two layers of wall coated with mercury, and then take away the air between the two layers, forming a vacuum. This vacuum flask, called & other; Du bottle & throughout; , can make the inside liquid regardless of ling, hot temperature remain unchanged within a certain time. Due to the vacuum flask is mainly used for hot water heat preservation in the family, so it is also called thermos. The structure of the vacuum flask is not complicated. Intermediate for the double deck glass inside, between the two layers into vacuum state, and silver plated or aluminum, vacuum can avoid heat convection, glass itself is a poor conductor of heat, silver plated glass containers can be internal to the external radiation heat reflection back. Cold storage liquid on the other hand, if the bottle, the bottle can prevent the outside heat radiation in the bottle.

the content of the vacuum flask and air can completely isolated, to avoid the product due to contact with air oxidation, bacteria, and with its high-tech concept promotion product. On the market of vacuum flask is made up of a cylinder into spheroid container plus a placed at the bottom of the piston. Its design principle is to use a contraction of the spring force, and do not let air into the bottle, create a vacuum, and the use of atmospheric pressure to push the bottom of the piston to move forward. But because of the spring force and the atmospheric pressure can't give enough power, so the piston can't and bottle wall joint is too tight, otherwise the piston will be caused by the rise of resistance to progress; On the other hand, if you want to get piston is easy going and easy leakage of material condition, therefore the vacuum bottle is very high to the requirement of manufacturers professional.

the above content, choose high quality vacuum flask requires to choose the professional manufacturer of cosmetics bottles of guangzhou, guangzhou cosmetics packaging co. , LTD to & other; Professional quality, excellence & throughout; For the purpose to & other; Science and technology first, people-oriented, honest & throughout; As the business philosophy, and other Service customer, customer satisfaction, and improving customer & throughout; As the goal, products with good quality and good service won the praise of all the partners, to get all the businessmen cooperation support, formed a good sales environment.
