PVA GLUE REPORT
SCIENCE ASSIGNMENT

PURPOSE
The purpose of this investigation is to test the strength of three commercial PVA glues to find the strongest and the most financially viable option.
HYPOTHESIS
The bond between wood to wood will have a better bond strength than the wood/plastic.
MATERIALS:
1. GLUE 2. WOOD 3. PLASTIC 4. WEIGHTS (500G,1KG,2KG) 5. RETORT STAND 6. BUCKET 7. CHAIR (FOR SAFETY REASONS) 8. PADDLEPOPSTICKS 9. CLAMP
METHOD:
1. Drill a hole in three of the paddle pops and all of the rulers. 2. Glue holed paddle pops to paddle pops and rulers to paddle pops. 3. Allow to cure for at least 24 hours. 4. Set up a retort stand on side of bench and clamp it there. 5. Fasten the paddle pop into the stand, making sure the hole is at the bottom. 6. Suspend weights from the hole in the paddle pop. 7. Measure the breaking point of the bond. 8. Record all the results and repeat the process for all other tests.
RESULTS:

TOTAL | GLUE A | GLUE B | GLUE C | AVERAGE | 2195 g | 955.6g | 2505.5g | AVERAGE WITHOUT ANOMALIES | 1656.25g | 657.2g | 1935.7g |
GROUP GLUE A GLUE B GLUE C
*MEANS THAT THE RESULT IS AN ANOMALIE. HOW DOES THIS ANOMALIE CHANGE THE DATA (refer to this graph ^^^)
ANALYSIS:
ITEM: 1 –
The purpose of this experiment was to test the strength of the bond between three types of glue on two different surfaces.
ITEM: 2-
The amount of glue was kept the same by keeping it to one drop. The measurement between/overlapping of the paddle pop sticks we kept were the same measurement at 2cm and 1cm for the drop of glue. The duration of the experiment conducted was the same. It was done in the

    (b) An experiment is to be conducted to determine the effect of temperature on the adhesive strength of C-glue. The glue will be applied to a material at either 10ºC, 15ºC or 20ºC. The experiment will be conducted separately for two different types of material (metal and plastic), as the effect of temperature is expected to differ for the two materials. Ten pieces of metal and ten pieces of plastic will be tested for each treatment.…

    Lab Report on Paper Towels

    For the first experiment we did the test for strength. We used a 600 mL beaker which we placed the sample paper towel over the opening of the beaker. The size of the sample towel was .234 m2. The paper towel was held it in place with a standard rubber band that was wrapped around the top of the beaker one time. We then took 5 mL of water and poured onto the paper towel. The weights that we used were 27 g each. The weights were placed on the paper towel one weight at a time until the paper towel ripped. The total amount of weight that it took to rip the paper towel was recorded. The process was then repeated for the second brand of paper towel.…

    Case Study: Riordan Manufacturing

    The suggested solution to the pollution caused by current adhesive material is to replace it with organic water-based adhesives. It is also suggested that the current application methods of applying adhesive materials be re-evaluated to reduce the amount used and minimize costs. Rolando (2010) suggested that using less adhesive, either through a superior product technology or an improved manufacturing technique, will prove beneficial for the environment. Rolando also mentioned that the adhesive industry is ahead of the green curve in terms of recyclability, environmental impact, and reducing volatile organic compounds. Roland concluded by stating "Adhesives have the capacity to far outreach the surfaces to which they are bonding. Therefore, a small 5% cutback in the amount can be easily attained" (Rolando, 2010,…

    General Chemistry Project 1: Polymer Ball

    Our assignment in this project was to create a bouncy ball for a company using polyvinyl alcohol (PVA), polyvinyl acetate solid and sodium borate, by varying the ration of ingredients and to determine the best recipe for our bouncy ball. The company chose the materials because of their odorless and nontoxic properties. PVA is a water-soluble synthetic polymer and has adhesive properties. It has a high strength and flexibility property. But this also depends on how much water is absorbed. The polymer will lose its high bendable strength as more water is absorbed. Polymers are substances that are built completely…

    Loctite Adhesive

    Executive Summary With the introduction of a unique low-cost adhesive dispensing product named as Bond-A-Matic (BAM), Loctite Inc is seeking to resolve dispensing issues such as clogging in smaller adhesive bottles. As a leader in development of high-performance adhesives and sealants for industrial and consumer applications, Loctite has a mission to become the premiere worldwide marketer of instant adhesives for industrial use by 1985. By increasing product awareness & brand recognition for Super Bonder, a CA adhesive product line, Loctite has improved sales revenue in 1978 over the previous year’s sales. With the idea of complementing Super Bonder, Loctite is hoping to expand adhesive dispensing equipment sales by introducing this new product. Bond-aMatic will be positioned as the low cost dispensing equipment for Super Bonder adhesive users. Situation Analysis CA sales were increasing at a rate of about 20% annually (twice the total adhesive market growth) and industrial adhesive use is outgrowing consumer market. Also based on a market research survey in 1977, it is found that 60% of purchasers bought less than a pound of CA adhesives while 55% of sales volume accounted for by small firms with fewer than 20 employees. By solving some of the problems (such as clogging) in dispensing adhesives, Loctite can improve its sales of industrial use CA adhesives. The current situation is further analyzed in detail in terms of consumer behavior, competition, Loctite’s core competencies & SWOT analysis for Loctite (see appendix A, C for information). Objectives for Bond-A-Matic Launch The launch of Bond-A-Matic product will be guided by two primary objectives 1) to catalyze Super Bonder sales with the help of complementary…
