Aangepaste blikboksgroothandel: tegnologie wat gebruik word vir gehalteversekering

Deur die jare heen wen die vervaardiger van gepaste blikkassies groothandel. Blikverpakking word 'n noodsaaklike deel van verskeie bedrywe, met voedsel bo-op. Elke dag kom miljoene blikkies in die mark.

To ensure the quality of these cans, there are several inspection standards intact. However, it seems that despite the extensive efforts of plant quality control systems, there is still a small percentage of cans that are defective.

These cans tend to have an adverse impact on the integrity of tin packaging. In addition, they sometimes end up contaminating the food products which is extremely dangerous for human health. Therefore, manufacturers should incorporate quality control operations within their manufacturing plants.

However, it seems that the inbuilt quality control operations have limited capabilities in terms of analytical chemistry. To ensure the quality of the cans, the companies either rely on independent laboratories or the manufacturer’s laboratory.

These laboratories help find and characterize the problems with the cans. In addition, they assist in removing the root cause by troubleshooting the operations. There are different types of technology that you use for the identification of the problem.

In this article, we are going to focus on some of these technologies. So, without any further delay, let us get straight to the point!

Identifying and characterizing Tin Box Defects

For more than 100 years, the food packaging industry has been using tin-plated steel cans to preserve and increase food life. Over the years, there has been great progress in terms of box designs, materials, external or internal protective coating, chemical process monitoring, manufacturing equipment, quality instrumentation, and quality control methods.

The quality and the integrity of the tin box depend upon their manufacturers. They need to ensure that cans or boxes are of high quality. Once, they are sure of the quality, the next step is to send them to the food industry for food storing purposes.

Despite the rigorous quality control procedures, something defective tin boxes end up in the market. They manufacturer learns about them via customer complaints. In this case, they use their internal and incoming quality controls to eliminate the respective problem in the next batch.

In worst cases, the manufacturer might have to shut down the production line in order to determine the cause of the defect. After all, determining the root of the problem would be highly important to the manufacturer.

Manufacturers do use a number of technologies to determine the defect in an effective and efficient manner.

Tegnieke en tegnologie

Belangrike blikvervaardiger vervaardig vandag elke dag honderdduisend tot etlike miljoen blikkies. Daarom sal enige gebreke wat tydens die gehaltebeheerprosedure geïdentifiseer word, 'n groot impak hê.

Dit beteken dat al die blikkies wat in die betrokke groep vervaardig word, waarskynlik die spesifieke defek het. Dit is iets wat die vervaardiger nie so nou en dan kan bekostig nie.

In die meeste blikkies en aluminiumstaalblikkies pas die vervaardiger 'n organiese beskermende laag op die binnekant van die blikkie toe. Die doel van die bedekking is om te voorkom dat die voedsel direk met die blik in aanraking kom.

Checking the metal exposure inside the can is among the major quality control tests. The manufacturer use Enamel Rater instrumentation to determine metal exposure. What happens is, you fill a sampling can with electrolyte.

The electrolyte than absorbs into the liquid and it comes in contact with the side or the bottom of the can. Then, you will apply voltage to the can. The voltage needs to be directly proportional to the amount of exposed metal.

In case the amount of exposed metal is great, the can is rejected. However, an extremely small amount of exposed metal is acceptable. There are gas bubbles that are due to the reversing system’s polarity. The electrochemical reactions cause these bubbles.

The inspector uses these bubbles to identify the exposed area. In case, the area is great, the troubleshooting process starts effectively.

Inspeksie met lae krag mikroskoop

Vervaardigers van persoonlike blikboksgroothandel gebruik beide die visuele ondersoek van die blikkies saam met 'n lae-krag mikroskoop om die metaalblootstellingsfoute te identifiseer. Oor die algemeen gebruik die vervaardiger 'n stereomikroskoop.

Daar is egter ook ander soorte mikroskope beskikbaar. Visoog en kraters is een van die gewone gebreke wat vervaardigers moet vasstel. Dit is die sirkelontwatering van die laag op die metaal. Die bedekking is gewoonlik van 'n vaste besoedeling. In sommige gevalle is dit selfs die onversoenbare vloeistof, insluitend masjienolie-mis.

Soms is die blootgestelde metaal te wyte aan die gebreekte blase van die coating. Dit kom voor wanneer die blik in die verhardingsoond is om dit te bedek. Die blootstelling van metaal aan die produk lei tot twee hoofprobleme, eerste metaalkorrosie en tweede migrasie van metaal na die produk.

Metaalkorrosie lei uiteindelik tot die lek van die produk. Iets wat alle vervaardigers se behoeftes ten alle koste moet vermy. In die meeste gevalle het die vervaardiger nie die nodige analitiese instrumente vir die identifisering van kontaminante nie.

Daarom moet hulle die monster na 'n ander laboratorium stuur vir verdere ontleding.

Hegtingstoets

Nog 'n algemene toets wat vervaardigers van blikbokse doen om die hechtingseienskappe van die eksterne sowel as die interne coating te kontroleer. Die normale hechtingstoets sluit in dat die blikkies in warm water gedompel word nadat die blik se sywande oopgesny is.

After removing the cans from the hot water, they are dried and scribing of the coating is done. Next, you have to apply tape over the scribe marks. Then, instantly pull that tap off. In case, some coating comes off with tape, the manufacturers instantly have to take the next step.

They need to start the troubleshooting process immediately. Coat adhesion failure is often the result of either under-cured or over-cured conditions. In addition, surface contaminants can also result in this problem.

For adhesion failure analysis, the manufacturer generally has to turn towards analytical laboratories.

Laboratory Instrumentations

Analytical laboratories are well-equipped with a number of instrumentations that they use for analyzing the custom tin box wholesale. Below, we have listed these instrumentations.

Optical Microscope

Daar is twee verskillende soorte optiese mikroskoop, verbinding en stereomikroskoop. U kan albei hierdie mikroskope gebruik, afhangende van die filters wat die defekte waarneem en die beligtingstoestande. In sekere gevalle word hierdie mikroskope ook gebruik vir die uitvoering van mikrochemiese toetse.

Hierdie toetse is effektief as dit kom by die kenmerk van kontaminante. Daarbenewens kan u dit gebruik om die gepoleerde deursnit en frakture van metaal te ondersoek.

Elektronmikroskoop

Scanning Electron Microscope (SEM) is 'n ander gewilde apparaat wat gebruik word vir die inspeksie van groothandel in blikdosers. Dit word soms saam met optiese mikroskope gebruik om die gebreke van die blikke te bepaal.

Usually, the laboratories use this particular method for inorganic material’s characterizing. In addition, it is possible to take images that are clear. Thus, making it easier to analyze the fractures of the cans.

Infrared Spectroscopy

Generally, people call Infrared Spectroscopy the Fourier Transform Infrared spectroscopy. The main purpose of these tools is to identify organic materials such as varnishes, inks, or oils. They also help in identifying cleaning chemical surfactants.

We often see these surfactants in manufacturing operations.

Importance of the Right Manufacturer

For custom tin box wholesale, it is vital for you to make the right decision in terms of tin-box manufacturer. Relying on an amateur would eventually lead to a bad brand name. You simply cannot go about choosing any random gift tin box supplier.

U moet let op hul gehaltebeheerstelsels om te verseker dat dit slegs die blikkies van die beste gehalte lewer. Tin-Packing is onder verskillende vervaardigers van blikkies. Hulle is die toonaangewende verskaffer van blikkieskaste vir geskenke.

Hulle lewer blikbokse van die hoogste gehalte. Om hul gehalte te verseker, laat hulle hul blikkies streng ontleed- en toetstegnieke ondergaan. Hulle sorg dat elke blikkie van daar af perfek en foutloos is.

Die doel van Tin-Packaging is immers om 'n gladde en langdurige verhouding met hul huidige en potensiële verbruikers te hê.
