Abstract

The titanium chopsticks are made of titanium metal or titanium alloy, which is preferably Ti-Al-V-Fe-Zr-Nb alloy of strengthen 800 MPa and coefficient of extension 10 %. The titanium chopsticks are light, non-toxic, anticorrosive, high in strength, high in heat resistance and astringent, and has deformation, bending, low heat conductivity, high wear resistance, long service life, clamping force similar to bamboo or wooden chopsticks. They are suitable especially for use frying and roasting, and suitable for sterilizing through soaking in disinfector and at high temperature, are environment friendly and fashional.

Description

Titanium chopsticks

Technical field

The present invention relates to tableware, relate to the titanium chopsticks of making specifically by titanium metal or titanium alloy.

Background technology

Make a general survey of the development history of China with the chopsticks civilization, from chopsticks goods such as then iron of stone, bone, wood, bamboo, copper, silver, stainless steel, plastics, every kind of chopsticks all have the effect and the limitation in its generation year.Bamboo and wood, yielding, flexible, the intensity difference of plastics chopsticks, and can't reach the requirement that really cleans up, being detained easily, breeding at the chopsticks surface bacteria, disposable chopsticks commonly used is gone back the grievous injury forest reserves, and is unfavorable to environmental protection.Iron, copper, silver, stainless steel chopsticks proportion are all bigger, so chopsticks are all heavier, the easy oxidation of the chopsticks of plain metal goods, perishable, what stainless steel chopsticks contained is micro-harmful, and cunning in use (holding force is poor) and easy heat conduction are not suitable for friedly, and occasions such as barbecue are used chopsticks.

Titanium is that reserves occupy the 9th element in the earth's crust, is the 3rd human outside iron, copper metal.Titanium metal is the metallic substance that has DEVELOPMENT PROSPECT, because it has abundant reserves on earth, titanium metal also has many superior characteristic simultaneously.Titanium only was used to hard-core technology fields such as aviation in the past, and titanium progressively more and more is widely used in our daily life now.In order to overcome the defective of above-mentioned chopsticks, the inventor is being engaged on the titanium metal applied research basis for many years, has developed the Novel Titanium chopsticks of being made by titanium metal or titanium alloy, to fill up the blank of market product.

Summary of the invention

The invention provides a kind of titanium chopsticks, is to be that material is made by titanium metal or titanium alloy.Characteristics such as that titanium chopsticks have is light, corrosion-resistant, nontoxic, high strength, thermal conductivity are little, anti-skidding, easy cleaning sterilization, long service life, can be in catering industry and daily living article wide popularization and application.

Titanium metal of supplying on the market and various titanium alloy can be used as the starting material of making titanium chopsticks.Preferred titanium alloy is made up of following prescription:

Component content (weight %)

Titanium 86-95

Aluminium 2-5

Vanadium 1-3

Iron 0.5-1.5

Zirconium 0.5-1.5

Niobium 1-3

In titanium, add the titanium alloy that aluminium, vanadium, iron, zirconium and niobium are made, have higher intensity, its limit yield strength σ _bReach 800Mpa, unit elongation δ is 10%, and has machinability and polishing performance preferably, makes its making that more is adapted to chopsticks and processing attractive in appearance.

The processing method that titanium chopsticks are produced:

Get and be pressed into electrode → after each amount of metal by above-mentioned titanium alloy prescription mixes for making the alloy homogenizing, carry out the smelting → heating of secondary consumable, forge, to change crystal structure, improve performance, and make certain dimensions → hot rolling, rolling with the titanium alloy blank → reshaping that obtains the manufacturing chopsticks, to obtain to make the material → cutting of chopsticks, be spun into titanium chopsticks → polishing, engraving patterns → packing warehouse-in.

Titanium chopsticks of the present invention are that a product blank has been filled up in market, and it has gently; Nontoxic; Erosion resistance can be antiacid, alkali, salt, and the solidity to corrosion in wet chlorine and seawater is particularly outstanding especially; The intensity height, especially titanium alloy intensity generally can reach 380-1000Mpa, and chopsticks are not yielding, not flexible, wear resistance good, long service life; Distinctive thermal resistance and puckery lubricant nature, titanium chopsticks have the holding force similar to the bamboo and wood chopsticks when using, again because of being difficult for heat conduction, overcome " cunning " (holding force is poor) and transcalent defective when plain metal chopsticks are used, therefore be specially adapted to fried, roast and use chopsticks with occasions such as chopsticks.Titanium chopsticks alternative bamboo and wood chopsticks, especially disposable chopsticks can be saved timber, protect forest resources, and help environmental protection.Titanium chopsticks metallic surface bacterium can't be detained, breed, and cleans easily, and available any sterilizing agent soaking and washing is particularly suitable for high temperature and sterilizes fast, can really accomplish hygienic environment-protecting chopsticks.And owing to be metal products, decorative surface is strong, can use high-tech such as vacuum plating, laser sculpture, makes the surface more attractive in appearance, fashion.The current era that develops rapidly in new and high technology, the titanium chopsticks that titanium metal or titanium alloy are processed into enter in ordinary people's the life, particularly to industries such as hotel, Food Specialties industry, tourism, wedding celebration souvenirs, can both promote the hygienic environment-protecting fashion new concept of China's daily living article with its unique charm.

Embodiment

Get titanium 92kg, aluminium 3kg, vanadium 2kg, iron 0.75kg, zirconium 0.75kg, niobium 1.5kg is pressed into electrode after mixing, and carries out the secondary consumable and smelts, and makes the alloy homogenizing, and reheat forges for 1100 ℃, and makes 60 * 60mm ²Dimensions, under 1100 °, carry out hot rolling again, obtaining diameter is the blank of the manufacturing chopsticks of 8.5mm, reshaping is rolled into 5 * 5mm ²The material of the manufacturing chopsticks of specification is pressed the shape square top and round bottom of chopsticks design requirements, cuts or is spun into chopsticks, and then polish, and depiction promptly gets titanium chopsticks finished product.

Claims (2)

1, a kind of titanium chopsticks is characterized in that by titanium metal or titanium alloy being that material is made.

2, titanium chopsticks as claimed in claim 1 is characterized in that described titanium alloy material is made up of following prescription:
