قبل أن نتعرف على عيوب ومزايا خشب mdf من حيث الاستخدام، دعنا نعرف أولا أنه من أنواع الخشب  المعاد تصنيعه من بقايا الكرتون والأخشاب، حيث تتم معالجته صناعيا، بالإضافة إلى كبسه تحت ضغط ودرجة حرارة مناسبين لتشكيل الألواح.

ما هو خشب الـ MDF؟

  • يتم تصنيع الألواح الليفية متوسطة الكثافة (MDF) بمجموعة متنوعة من الخصائص الفيزيائية والأبعاد،فيمكن قطعها وثنيها حسب مواصفات المنتج المطلوبة.
  • ألواح MDF عبارة عن منتج مركب تم إنتاجه من بقايا و رقائق أنواع مختلفة من الخشب، ويتكون عادة من ألياف السيليلوز المدمجة مع راتنج صناعي (مواد لزجة تتحول إلى بوليمرات صلبة بعملية المعالجة).
  • وهي معالجة معقدة ودقيقة تسمح بانصهار الحرارة والضغط معا لتشكل المنتج النهائي المطلوب.
  • ويمكن إدخال مواد أخرى أثناء التصنيع لإضفاء خصائص معينة، مثل السطح الأملس، والكثافة، استواء اللوح وتجانسه، وخلوه من الأنماط التي تفسد مظهره الجمالي.
  • ورغم كونه صناعيا لكنه مثالي للمطابخ؛ لأنه مقاوم للرطوبة.

عيوب  خشب MDF ؟

من أبرز عيوب ألواح خشب mdf:

  1. عدم مقاومته للماء، فنرى أنه يتعرض لامتصاص الماء، مما يجعل الألواح تنتفخ.
  2. غير ذلك، فالعمر الافتراضي لا يتجاوز 4 سنوات، ثم يبدأ في التشقق والانكسار.
  3. ونستنتج من ذلك أيضا أن الخشب لا يتحمل الضغط.
  4. خشب بهذه المواصفات لا يكون من السهل إصلاحه، ويتوقف هذا على كثافة اللوح أيضا.
  5. المواد التي تدخل في صناعته ليس صحية.

من أفضل خشب MDF او HDF؟

كلا النوعين يضاف إليهما مادة كيميائية معينة لتعزيز الجودة والصلابة، ولكن هناك فرق بين نوضحه فيما يلي:

خشب mdf

يطلق اختصارا على الإسم العلمي (Medium Density Fiberboard) ويوصف بأنه ذو جودة أقل من (hdf)  نتيجة زيادة المادة الكيميائية في مقابل انخفاض كثافة الخشب الطبيعي.

ويكون سعره أقل كثيرا من باقي الأنواع الموجودة في السوق.

خشب hdf

ويعرف علميا بإسم (High Density Fiberboard) ويتيمز عن نظيره بجودة أعلى نسبيا، نظرا لكثافة الخشب الطبيعي المستخدمة في صناعته، وإخراجه على هذا النحو مع تقليل المواد الكيميائية.

    Today, I went to the beachfront with my children. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is completely off topic but I had to tell someone!
