This refers to the size of an individual particle of carbon black, the smaller the particle size the larger the specific surface.

Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, or ethylene cracking tar. In these applications, particle size and surface characteristics contribute to tinting strength and blackness. 0000007779 00000 n P�{�j�����|F�xz� vOr�nۨ�E��$H���Q�.#x\��n�+�F�&�����ϔ�\�7e�ٴ x���j'�m`&��VR�[:bl���K"b#�Zx�83��@[5�x��ChE_�2Z��U�� w��K4��e���h�X%�ط�G. 2 0 obj 0000059749 00000 n 3. 0000006739 00000 n Tobacco Smoke Soot Blowing - Boiler Tubes Bacteria Fertilizer Plant Dust & Fumes Paint Pigments: Window NC Units. %PDF-1.6 %���� Powder is first dispersed as an aerosol and the particle size is subsequently measured with a differential mobility classifier and an aerosol concentration detector. ?N�UW��2��N+���_E��� �d��HM�%��Vx�S�y�*�&a;�;�X��.���ן�v~_��b� F�m�a*�%W�/$^^�u����࿸��4��e��=8��玓���}z�?߄�r#�B�o{������h�ic`��:9ە!�:SR>�2��k��t�η�����6h��g����Y[�#������nO�D�\a��&�WM�/nz[���W�O|�0B��X���"CTG|i�f#y(���n��+�vTP�?�c�H�����)��*�Hޖ�b��._����'Y���5 ��%��W�}N3���x�;4 gK���7�n�ܑ O!
