| چکیده | ||
| در این تحقیق امکان استفاده از پوشش‌های سوپرکروم و فانتاکروم بر سطح چوب‌های راش و صنوبر بررسی شد. در ابتدا نمونه‌ها به ابعاد 2×10×10 سانتی‌متر تبدیل شد و پس از پوشش‌دهی با رنگ‌های سوپرکروم و فانتاکروم، آزمون‌های چسبندگی کششی و خراشی، زاویۀ تماس و خاصیت انعکاس آینهای سطح بر روی سطح آنها صورت پذیرفت. همچنین به‌منظور بررسی خواص سطحی پوشش، مطالعات میکروسکوپی نمونه‌های پوشش‌داده‌شده با پوشش فانتاکروم با استفاده از میکروسکوپ نوری انجام گرفت. نتایج نشان داد که زاویۀ تماس نمونه‌های پوشش‌داده‌شده با سوپرکروم و فانتاکروم در مقایسه با نمونۀ شاهد در هر دو گونۀ چوبی راش و صنوبر به‌طور چشمگیری افزایش یافت. بیشترین و کمترین میانگین چسبندگی کششی پوشش‌های سوپرکروم و فانتاکروم به‌ترتیب در نمونۀ راش پوشش‌داده‌شده با فانتاکروم و نمونۀ صنوبر پوشش‌داده‌شده با سوپرکروم بود. همچنین نتایج آزمون چسبندگی خراشی تأییدکنندۀ نتایج چسبندگی کششی بود. پس از پوشش‌دهی خاصیت انعکاس آینهای سطح سطح نمونه‌ها به‌طور معناداری افزایش یافت و بیشترین خاصیت انعکاس آینهای سطح مربوط به پوشش فانتاکروم در نمونه‌های راش و صنوبر به‌ترتیب به مقدار 8/141 و 7/141واحد براق (GU) بود. همچنین نتایج بررسی میکروسکوپی نشان داد پرایمر اولیۀ پوشش به مقدار 4 میکرون در بافت چوبی نفوذ داشته و پوشش نهایی کروم، فیلم پوششی (فیلم رنگی) به ضخامت 11 میکرون بر سطح چوب تشکیل داده است. | ||

| In this study, the possibility of using superchrome and Fantachrome coatings on beech and poplar surface was investigated. Initially, samples were cut into 2×10×10 cm dimensions and after coating with superchrome and fantachrome paints, pull-off and cross-cut adhesion, contact angle and gloss tests were performed on their surface. The properties of coated surface was investigated by light microscopy. According to the results, the contact angle of the coated samples with superchrome and fantachrome significantly increased compared with the control sample in both beech and poplar species. The highest and the lowest amounts of pull-off adhesion strength of superchrome and fantachrome coatings were in fantachrome-coated beech and superchrome-coated poplar, respectively. Also, the results of cross cut adhesion test confirmed the results of pull-off test. After coating, the gloss content of the specimens significantly increased and the highest gloss was related to fantachrome coatings on beech and poplar samples, 141.8 and 141.7 gloss units (GU), respectively. In addition, the results of microscopic examination showed that the primary primer of the coating penetrated the wood texture by 4 microns but the surface chrome coating was 11 microns thick on the wood surface. | ||
