Laminat Parkede Yanmayı Geciktirici Kimyasal Maddelerin Küf Mantarı Direnci Üzerine Etkilerinin Araştırılması

Investigation of Effects of Fire Retardant Chemical Substances on Mold Resistance in Laminate Parquet

Özet

Bu çalışmanın amacı laminat parkede kullanılan yanmayı geciktirici bazı kimyasal maddelerin küf mantarı üzerine etkilerini belirlemektir. Yüksek yoğunlukta lif levhalar (HDF) için lif kaynağı olarak %50 kayın ve %50 sarıçam kullanılmıştır. Liflerin arasına yanmayı geciktirici kimyasal maddeler eklenerek 6,5 mm kalınlıkta HDF levhalar üretilmiştir. Boraks, borik asit, amonyum polifosfat ve alfa-x yanmayı geciktirici kimyasalları tam kuru lif miktarına oranla %3, %6 ve %9 oranlarında pulverize şekilde eklenmiştir. Daha sonra elde edilen HDF levhaların üzeri overlay, dekor ve balans kâğıtları ile kaplanmış ve laminat parke levhaları üretilmiştir.

Abstract

The aim of this study is to determine the effects of certain fire retardant chemicals on mold resistance of laminate flooring. As a source of fiber for high density fiberboard (HDF) panels were used a mixture of %50 yellow pine and beech fibers. HDF panels were produced in 6,5 mm thickness by adding fire retardant chemical materials into fiber. In proportion to complete dry fiber essence fire retardant chemicals borax (BX), boric acid (BA), ammonium polyphosphate (APP) and alpha-x (AX) in pulverized form were added in the ratios of 3%, 6%, and 9%. Afterwards, surfaces of produced HDF boards were coated with overlay, decor and balance sheets and then laminated floorings boards were produced.Mold resistance of produced laminate flooring was explored. In the test, Aspergillus niger and Aureobasidium pullulans mold were used. To detect mold resistance, the test was made according to ASTM D4445–10. It was determined that 3%, 6%, and 9% additions of fire retardant (FR) chemicals enhanced mold resistance of laminat flooring. As a result, it was ascertained that type of chemical
