Abstract
[Ar] تقييم كفاءة الثيمول كاحدى اجراءات الصيانة والترميم تطبيقا على السجلات الورقية المصابة بدار المحفوظات المصرية دار المحفوظات الوطنية المصرية هى ثاني أقدم دار أرشيفية فى العالم من أجل حماية جميع الوثائق والأوراق الأثرية والتاريخية الرسمية من الضياع والسرقة. والدار تمتلئ بنحو 150 مليون وثيقة أثرية وتاريخية رسمية.الا انه وللأسف الشديد اغلب هذه المواد الأثرية قد تعرضت لتدهور بيولوجى مما أدى إلى خسارة كبيرة. ومن هنا تظهر أهمية استخدام مبيدات الفطريات وقد وقع الاختيار على أحد أكثر المبيدات شيوعا فى مجال الاثار وهو «الثيمول» لدراسة مدى كفاءته تجاه الفطريات عند استخدامه بتركيزات مختلفة. هذا إلى جانب دراسة أولوية الحفظ للأرشيف الورقى المكتوب بخط اليد لعقود الزواج «بمحكمة دمياط» لما له من أهمية كبيرة في إبراز معلومات غاية فى الاهمية وثائقيا وذلك بعد تعرضه لعدوى فطرية. استراتيجيات عمليات الترميم والصيانة التى تمت بالدراسة تتم من اجل الحفاظ على هذا الدفتر الورقى من أجل الحفاظ عليه لما يحويه من معلومات أثرية هامة. كما تم استخدام بعض التقنيات الفحوص والتحليل خلال الدراسة وهى: طريقة حيود الأشعة السينية (XRD) للتعرف على الحبر الكربونى، والتحليل الطيفى للأشعة تحت الحمراء (FTIR) لتحديد المادة الرابطة للاحبارالمستخدمة ومدى بلورة السيليلوزالمكون الرئيسى للورق، حيث أظهرت النتائج أن الحبر الأسود المستخدم فلا الوئاثق الورقية بالدفتر عبارة عن كربون وأن المادة الرابطة للحبر هى الصمغ العربي. تم تطبيق عدة خطوات لترميم الدفتر مثل عملية التنظيف، تثبيت الأحبار، فرد الأوراق، إصلاح التمزقات، تدعيم الأجزاء الضعيفة وإزالة الترميمات السابقة غير المناسبة.وعلى هذا تهدف هذه الدراسة إلى إلقاء الضوء على دار المحفوظات الوطنية المصرية وإبراز دورها المهم في حماية وحفظ الوثائق الأثرية والتاريخية فضلا عن تقييم كفاءة الثيمول تجاه الفطريات باستخدام تركيزات مختلفة مع شرح أهم إجراءات الترميم المختارة للدفتر الورقى المكتوب بخط اليد الخاص بعقود الزواج بمحكمة دمياط. [En] The Egyptian National Archives Dar-Elmahfouzat is the second oldest archive house in the world built in order to protect all the official archaeological and historical documents and papers from loss and theft. It possesses about 150 million official archaeological and historical documents. Unfortunately, all these archaeological materials are exposed to biological degradation which results in great loss. Hence the importance of using fungicides. The choice fell on one of the most commonly used in the field “thymol” and its efficiency towards fungi in different concentrations. The author gives the priority of conservation to this important handwritten paper archive of the marriage contracts' of Damietta court, because of their great importance to posterity and to highlight such significant historical data threatened by fungal infection. The specific conservation strategies employed to conserve this paper archive were meant to keep them safe and secure and to give us the important archaeological information that they contain. Also some analytical methods were used here: X-ray diffraction (XRD) method for identifying the carbon ink, Fourier Transform Infrared Spectroscopy (FTIR) for determining the ink binder and the paper crystallinity. The results revealed that the black ink was carbon and ink binder was Gum Arabic. Different types of conservation processes were used: Cleaning process; fixing the inks; flattening and crease removal; repairing tears and supporting the weaker parts in completion process; and inappropriate previous repairs removal. This study aims to shed light on the Egyptian National Archives Dar-Elmahfouzat and highlight its important role. Also clarifying its importance in protecting and preserving the archaeological and historical documents, explain the thymol efficiency towards fungi in different concentrations and the most important treatment procedures for the selected handwritten paper archive of the marriage contracts of the court of Damietta.
