lcd panel scrapping free sample

The material management-related scrapping process mainly relates to how to identify the material stocks which are related to scrapping, and the scrapping or write-off of those stocks from the system.

Generally, materials that need to be scrapped are maintained in the quality inspection stock or blocked-stock category. The quality inspection department will check the parameters of the materials and will give the final decision for scrapping. SAP has given the provision to scrap from all three of these stock types and SAP has provided three movement types for each of the stock types.

Scrapping from unrestricted stock is done with themovement type 551. Scrapping from quality inspection stock is done with movement type 553, and scrapping from blocked stock is done withmovement type 555. If the stocks belong to special stock types such as sales order stocks, consignment stocks, project stocks, etc., it is possible to maintain the special stock type during the scrapping process and a corresponding movement type will be used.

For the scrapping of materials, there are two transactions that we can use in SAP. We can use MIGO or MB1A, where the latter transaction code is obsolete in the latest SAP S/4HANA version. Follow the below steps in MIGO to carry out the scrapping movement.Select the activity as “goods issue”.

Once the scrapping movement is executed in SAP, two documents will be posted. One is the material document. The Material document will have the stock-related information such as the quantity reduced, movement type, date of the posting, etc. The second document is the accounting document which will have the financial information of the scrapping process such as the accounts in which the debit and credit postings happened. The cost of the scrapped material will be posted to a cost center in SAP.

While analyzing the strength properties, slightly smaller values were observed for the concretes with LCD admixture, in relation to the reference concretes CI.0 and CII.0. The differences in the obtained values are differentiated, exhibiting no clear tendency. They are most pronounced in the tensile strength test; however, due to the high coefficient of variation (over 10%), they cannot be subjected to a comparative analysis. Generally, it can be stated that lower values were usually found in the concretes with LCD addition. Such observation can be explained both by a higher air content in the concrete mixtures with LCD admixture (the considered concretes exhibited diversified consistency with low degree of liquidity within two classes), as well as the conchoidal fracture of LCD grains. The conchoidal fracture, due to its glassy and smooth texture, deteriorates the mechanical adhesiveness of cement paste to aggregate granules, despite its low porosity found while examining the interfacial transition zone (ITZ). Nevertheless, the low share of the admixture should reduce its significance. It should also be emphasized that extending the maturation time substantially mitigates the differences in compressive strength values. Following 90 days of maturation, all concretes reached the same class. which is especially prominent while applying the CEM II/B-S 42.5 N cement that is characterized by a slower improvement of the strength parameters in relation to CEM I 42.5 R.

The obtained correlations can be described by the equation y=0.39x2−0.02x−2.23, which is characterized by a coefficient of determination R2 = 0.83 and relatively low errors in the intercept (respectively 28%, 25%, 28%). The higher the water-tightness, the higher the frost resistance and the lower the mass loss. The reference concrete CI.0 is characterized by the lowest water-tightness (deepest water penetration), which corresponds to the highest mass loss during the water tightness test. An increase in LCD admixture to 2% resulted in 3-fold decrease in the mass loss of the samples.

Based on the research of Batayneh et al. [64] concerning the impact of various waste materials on the properties of concretes and hardened concrete, it was found that the use of aggregate made of recycled concrete, due to the shape and texture of the grain surface, significantly reduces the workability of the concretes. Similar observations were made when using crushed plastics. In our own research, the impact of LCD additive with significantly smaller amounts and completely different mineralogical and chemical characteristics did not significantly affect the consistency of the mixtures.

The use of 20% recycled plastics or concrete aggregate according to Batayneh et al. [64] reduces the compressive strength compared to reference concrete with natural aggregate. Despite the small amounts of LCD addition used in our studies, similar relationships in compressive strength values were observed in the early maturing periods (see Figure 5). However, after a longer maturing period (90 days), the same compressive strength classes of the tested concretes were obtained.

As a result of research of Mahesh and co-workers [65] regarding the impact of waste from polyethylene plastics, it was found that despite the reduction of early compressive strength of tested concretes (5–10% of the used waste), their compressive strengths after 28 days were comparable to the reference concrete [65]. Similar correlations were observed in own research after the use of LCD as an additive (Table 10).

Many states will not let you scrap these, so check with your local laws before trying to scrap them. Make sure that they are empty before scrapping them.
