Setting of transmission during the particular production of glass substratesPosted by McFadden Skovsgaard on January 22nd, 2021 In the manufacturing process associated with the existing goblet essence, vertical transmission process, horizontal transmission method, air-float contact-free transmission method as well as upset application of each tranny method are normally implemented. The application of these kinds of different sign strategies within the manufacturing process of a glass substrate is examined.
(1) vertical transmission: straight sign is suitable for any overflow melting method to generate glass, its means involving transmitting is: by a glass heater forming after arriving out, all the way down into the particular clean room nice and clean level is less than thousands of, along with a mechanical arm, typically the cup substrate the high quality section ( < 15 mm) clamping glass above, make the entire cup in natural point out, straight manipulator clamping wine glass, area the glass in the particular intelligent transmission program, could achieve often the objective connected with vertical transmitting.
Advantages: Whenever the glass base can be annealed from the furnace, the surface heat regarding the a glass essence can be as high since 300℃ or above, in addition to any point of individuals contact will leave flaws on the surface involving the glass essence. insualted glass fabricator can stay away from smog as far as achievable, without triggering manufactured scuff marks on the surface with the glass substrate, which performs a definitive role in the following process of the particular goblet substrate.
Disadvantages: The particular glass substrate clamping length is usually short, prone for you to glass dropping phenomenon, often the glass inside the transmission, presents a natural straight, uncomplicated to be affected by way of the air flow wiggling, which results in the collision having tools.
(2) the amount of transfer: using this method will be suitable for the drift goblet manufacturing (represented by the Japanese people AGC), and even its means of tranny is: the glass released through the furnace, lateral movement through a protective gas (N2 and H2) in pan bath, again through the key tranny and edge roller connected with external force, the organization connected with a certain width, typically the density of the glass, after building cooling, sent to annealing kiln, together with then use the PVC stuff roller, horizontal move give glass, Cheng Duan delivered to each program.
Advantage: typically the molten glass moves through the central heat and floating inside relative density involving tin fluid on often the surface, under the a result of gravity and surface tension, liquid glass in the container surface spread, pass on, the organization of the surface area simple, no wave support, thickness of the goblet substrate, typically the visibility of its products will be tougher, because through the jar surface processing, more simple, under the action associated with area tension, formed the kind of exterior is neat, flatness is better, typically the characteristics of optical overall performance is more robust.
Disadvantages: When the glass is transferred flat to the tin fish tank, several complex chemical allergic reactions take place in some sort of relatively closed environment due to use of metal jar liquid as floating medium sized and even nitrogen and hydrogen varying gas as defensive fuel. Some of the particular products in these reactions will take many cup defects, affecting the level of quality of the product.
Second, the particular upper surface in the goblet is smoother compared to the reduced surface, because the reduce surface is in entire experience of the tin option, unavoidably leaving some remnants, resulting in fewer smoothness than the upper floor.
(3) Air floating transmitting: This process is suitable for the particular glass base after concluding. The tranny method is as follows: this glass substrate immediately after ending has reached often the customer's demands. At this moment, in order to ensure the top quality stability of the glass base to the very best level, the non-contact weather hovering transmission method is frequently applied to transmit the a glass essence in the clean up bedroom.
During transmission, typically the lower edge of the glass substrate is positioned about the roller at the particular bottom on the air float strip.
insualted glass fabricator revolves to push this a glass substrate to move. The oxygen float unit is based in the back of this glass substrate with a good inclination of about 80°.
Advantages: air floating unit normally include air floated by simply multiple root of hanging of the group, in the process connected with sending glass substrate plus the distance between the floating article will be zero. 1 ~ 2 mm, generally in order in order to assure the quality regarding the glass espèce, hanging article groups with a glass, there is no get hold of involving gas and this surface on the article itself has a high flatness requirement, usually under deal with in 0. 05 millimeter, and also this guarantees the goblet essence by air-flotation document, avoid air-flotation friction prospect to nothing.
Weakness: this glass substrate is about 80 ° willing are usually considered, is to prevent 90 ° vertically sent any time can have typically the risk on the CDA blown glass, if will be transmitted level air flotation, the glass will be hanging in the air flow floating bar, cannot effectively control to the cup, way at the very same time need to get additional a great deal of CDA to guarantee distribution level required for blowing gas.
