摘要或動機

This study evaluates the corrosive resistance of strong acid and base for laboratory
desks including epoxy resin products, plywood, carbonate products and boards. From
results,only the surface of expensive resin products can tolerate the exposure of
strong acid and base. The surface of other commercial materials was destroyed with
strong acid and base. The performance of laboratory-made desk surface for resistance
corrosion of strong acid and base was studied. Coating with Teflon paint on the
board could resistant the exposure of strong acid and base, but a drying long time
was the major shortage. Some of the chitin added could improve and tolerate the
scraping with knife. The results will offer to make a cheaper laboratory desk.

本研究主要是探討不同材質的實驗桌面,如環氧樹脂合成板、三合板、美耐板、一般木板等,其對強酸、鹼的抗腐蝕之極限濃度,進而研發自製經濟實用的耐強酸鹼實驗桌面。由實驗結果顯示,只有較高級昂貴的環氧樹脂合成桌面,才能夠耐高濃度的強酸、強鹼,普通的環氧樹脂桌面、三合板或美耐板其抗強酸、鹼性則不理想。若將一般木板塗以鐵氟龍漆,即可得抗強酸強鹼之桌面材質,但漆不容易乾燥,若添加適量的幾丁質於鐵氟龍漆中,則漆將極容易乾燥,可降低烘烤溫度,使木板不致因高溫烘烤而變形,此所得結果可作為製作價廉的抗強酸強鹼實驗桌面之參考。尤其本實驗所製作之板面以水果刀刮之,板面絲毫未受損,故值得我們廣為運用。
