Yüzey kaplamasına eklenen amonyum fosfat ve borik asidin yanma direnci üzerine etkisinin araştırılması

Öz

Özet

Çalışmanın amacı: Bu çalışmanın amacı, yüzey kaplamasına eklenen amonyum polifosfat (APP) ve borik asidin (BA) yanma direnci üzerine etkisini belirlemek olacaktır.

Çalışma alanı: Ahşap esaslı levhalarda, yanmazlık özelliğinin geciktirilmesini sağlamak

Materyal ve Yöntem: Yüzey kaplama karışımı kalsit, tutkal, yanmayı geciktirici kimyasallar ve su karışımından oluşmaktadır. Karışım içindeki tutkal (%10), BA ve APP (%1, %3 ve %5) oranı, kalsitin tam kuru ağırlığına göre belirlenmiştir. Yüzeyi 0.25 mm kalınlıktaki karışım ile kaplanmış MDF test örneklerinin yanma testleri ASTM E 69 standartlarına göre yapılmıştır. Örneklerin ağırlık kaybı miktarları dijital terazi ile belirlenirken, sıcaklık, O₂, CO ve NO değerleri Testo 340 M gaz analizörü ile ölçülmüştür. Her test için 30 saniye aralıklar ile 20 ölçüm yapılmıştır.

Sonuçlar: Elde edilen sonuçlara göre; kalsit ile kaplamanın yanı sıra yanmayı geciktirici (FR) kimyasal eklenmesi yanma direncini artırmıştır. En düşük ağırlık kaybı APP %5 ile muamele edilmiş örneklerde bulunmuştur.

Araştırma vurguları: Ahşap esaslı levhaların yüzeylerinin kaplanması ve bu kaplama içerisine FR kimyasalı ve mineral eklenmesi yanma özelliklerini geciktirmektedir

Abstract

Aim of study: The purpose of this study were determined the effect of ammonium polyphosphate (APP) and boric acid (BA) as surface coating materials on combustion resistance of MDF panels.

Area of study: To ensure the retardation of combustion properties of wood based panels

Material and Methods: Surface coating mixture consists of calcite, glue, fire retardant (FR) and water. The amount of glue (10%), APP and BA (1%, 3% and 5%) in the mixture was determined by the oven dry weight of calcite. Combustion tests of Medium Density Fiberboard (MDF) test specimens coated with 0.25 mm thickness of this mixture were carried out according to ASTM E 69 standards. Temperature, O₂, CO and NO contents of samples were measured with Testo 340 M gas analyzer while weight loss was measured with digital scales. For each test, 20 measurements were recorded at intervals of 30 seconds.

Main results: According to the obtained results, besides calcite coating, the increase of FR addition rate increased the resistance of combustion. It was found that the weight loss of the samples treated with APP 5% was the lowest (66,7%).

Research highlights: The coating of the surfaces of wood-based boards and the addition of FR chemistry and mineral to this coating delays the burning properties
