Abstract
The invention particularly relates to a complex thin-wall partitioned bin sealing and bonding method, and solves the problem that as the conventional complex thin-wall partitioned bin is poor in sealing effect, an inner ring of the partitioned bin is scraped and reworked. The method comprises the following steps: a, applying soapy water to the adjacent end surfaces of the outer casing and the left end of a threaded surface of the inner ring, checking a specific position of leakage, making a mark, and recording the leakage amount grade; b, cleaning the soapy water, and drying; c, applying sufficient seal glue, and enabling the glue solution to completely cover the leakage part; d, slowly vacuumizing a cavity formed by the outer casing and the inner ring, and when the glue solution cannot completely cover the leakage part, stopping vacuumizing and depressurizing; e, observing whether the glue solution overflows from the outer casing and the right end surface of the threaded surface of the inner ring, and if no glue solution overflows, repeating the step c and step d until the glue solution overflows; f, removing the residual glue solution at the left and right ends of the threaded surface, curing for 72 h at the ordinary temperature, and conducting airtight test examination. According to the method, the success rate of the airtight test is improved, and the sealing and bonding effects with the same quality can be kept all the time.
Description
Technical field
The present invention relates to compartment adhesive method, be specially a kind of complex thin-wall compartment and be sealing adhesive method.
Background technology
Complex thin-wall compartment has certain airtight pressurize requirement, and its helicoid is tightly connected position and is generally adopted the process of adhering and sealing. At present, known technique for sticking is manually to be equipped with aid to smear fluid sealant and complete bonding, owing to the connecting portion between each Assembly part is in irregular shape, fit clearance is not of uniform size, the yielding factor of shell part exists, it is inconsistent that operating mode smeared by the fluid sealant causing helicoid connecting portion, and process of particularly manually smearing easily is mixed into micro-bubble, thus affecting air-tightness.
Complex thin-wall compartment is made up of multiple parts, and wherein the helicoid connecting portion of shell body and internal ring requires to seal, air seal test 0.02MPa, and pressurize 10min does not allow leakage. In actual production, owing to raw material band is difficult to uniformly, the 352 glue processes of smearing are mixed into micro-bubble all can affect sealing, once after adhesive curing, air seal test is defective, shell body and internal ring cannot be dismantled, turning can only be taked to destroy internal ring, retain shell body intact. Therefore bonding defective causing that internal ring is scrapped and does over again, processing cost is higher.
Summary of the invention
The present invention is to solve that existing complex thin-wall compartment exists the problem that sealing effectiveness difference causes compartment internal ring to scrap and do over again, it is provided that a kind of complex thin-wall compartment seals adhering method.
The present invention adopts the following technical scheme that realization: complex thin-wall compartment seals adhering method, adopt following steps: a, at the abutting end topcoating suds of shell body and internal ring flank left end, by the particular location of air seal test leak check, line flag of going forward side by side and record leakage rate grade; B, suds are cleaned up drying; C, reveal particular location smear enough fluid sealants, make glue that leakage position is completely covered; D, the slow evacuation of cavity that shell body and internal ring are surrounded, the change of glue is observed on evacuation limit, limit, when glue not exclusively covers leakage position, stops evacuation pressure release; Whether e, observation shell body and internal ring flank right side have glue to overflow, and overflow without glue, repeat step c and d, until there being glue to overflow;F, remove the unnecessary glue in two ends, flank left and right after, ambient temperature curing 72h, carry out air seal test inspection.
Sealing adhering method of the present invention utilizes the mobility of glue, pass through evacuation, form pressure reduction leak position is smeared, make sealing surface operating mode consistent, synchronize to realize the filling of tiny leakage path, not by the restriction of number of channels, pattern, even if passage bends, intersection nor affects on, overcome existing complex thin-wall compartment and there is the problem that sealing effectiveness difference causes compartment internal ring to scrap and do over again.
Sealing adhering method rational technology of the present invention is succinct, air-tight test success rate is made to be risen to more than 98.7% by original 83%, and the bonding effect of sealing that homogenous quantities can be always maintained at, meet product airtight quality stability requirement, while workable, improve production efficiency.

Detailed description of the invention
Complex thin-wall compartment seals adhering method, adopts following steps: a, at the abutting end topcoating suds of shell body 1 and internal ring 2 flank 3 left end, by the particular location of air seal test leak check, and line flag of going forward side by side and record leakage rate grade; B, suds are cleaned up drying; C, reveal particular location smear enough fluid sealants, make glue that leakage position is completely covered; D, the slow evacuation of cavity that shell body 1 and internal ring 2 are surrounded, the change of glue is observed on evacuation limit, limit, when glue not exclusively covers leakage position, stops evacuation pressure release; Whether e, observation shell body 1 and internal ring 2 flank 3 right side have glue to overflow, and overflow without glue, repeat step c and d, until there being glue to overflow; F, remove the unnecessary glue in flank about 3 two ends after, ambient temperature curing 72h, carry out air seal test inspection.
In specific implementation process, mend glue operation and be carried out by professional; Clean environment degree should meet bonding demand, and ambient temperature must not lower than 20 DEG C; Mend glue process time unsuitable long, otherwise glue poor fluidity, mend glue weak effect.
