1、Designation: D 1199 86 (Reapproved 2008)Standard Specification forCalcium Carbonate Pigments1This standard is issued under the fixed designation D 1199; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n
2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers two types of high-contentcal
3、cium carbonate pigments, as follows:1.1.1 Type PCCalcium carbonate precipitate, preparedeither by complete solution or by carbonation of lime.1.1.2 Type GCGround mineral product.1.2 Six grades of pigments, based on particle size (see 3.3)are covered.1.3 The values stated in SI units are to be regard

Composition and Properties3.1 The pigment may be prepared by chemical precipitationor by the fine grinding of natural calcium carbonate containingminerals. If additional age
7、nts are used or any surface treatmentis given, their purpose shall be indicated; acceptance shall be asagreed upon by the purchaser and the seller.3.2 CompositionThe pigment shall conform to the re-quirements for composition prescribed in Table 1.3.3 FinenessThe pigment shall conform to the followin
8、ggeneral requirements for fineness for the grade specified:3.3.1 Grade I (Fine Paint Grade)This grade possessessubstantial amounts of material in the fine sizes, and is ingeneral essentially below 15 to 20 m maximum size. Coarseparticles retained on the No. 325 (45-m) sieve shall be lessthan 0.05 %.
9、 The maximum Specific Surface Diameter (SSD)shall be 2.5 m.3.3.2 Grade II (Coarse Paint Grade)This grade is char-acterized by substantial amounts in the 5- to 45-m range, andis lower in pigment value than Grade I. Coarse particlesretained on the No. 325 (45-m) sieve shall be less than 0.5 %.The maxi
10、mum SSD shall be 6 m.3.3.3 Grade III (Filler Grade)This grade is characterizedby substantial amounts in the 10- to 45-m range but with thecoarse particles retained on No. 325 (45-m) sieve less than25 % and a maximum SSD of9m.3.3.4 Grade IV (Putty Powder Grade)This grade pos-sesses less fines, and ha
11、ve substantial amounts of coarseparticles. The coarse particles, however, shall not exceed 30 %retained on the No. 200 (75-m) sieve. The maximum SSDshall be 12 m.3.3.5 Grade V (Superfine Grade)This grade is a super-fine ground natural limestone and is characterized by majoramounts less than 5 m and
12、a weight median particle size in therange of 1 m. The SSD is finer than 1 m.3.3.5.1 Particle size methods for Grade V that are applicableinclude transmission electron microscopy, scanning electronmicroscopy, and the Sedigraph.4Specific Surface Diameter canbe determined by BET nitrogen absorption. Th
13、e method ofmeasurement produces different values, therefore, the methodof measurement shall be agreed upon by the purchaser and theseller.1This specification is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings, Materials, and Applications and is the direct responsibility ofS

17、ken, PA 19428-2959, United States.3.3.6 Grade VI (Ultrafine Grade)This grade is an ul-trafine precipitated calcium carbonate and is characterized bymajor amounts less than 2 m and a median particle diameterdetermined by electron microscopy in the range of 0.05 m.3.3.6.1 Particle size methods for Gra
18、de VI that are appli-cable include transmission electron microscopy and scanningelectron microscopy. The Sedigraph will give weight medianparticle size values approximately 10 times greater (;0.5 m)than by microscopy. Since the method of measurement pro-duces different values, the method of measurem
19、ent shall beagreed upon by the purchaser and the seller.3.3.7 When closer control within a grade is required, thefineness requirements shall be as agreed upon by the purchaserand the seller.3.4 Dry Brightness or Dispersed ColorThe dry brightnessor dispersed color shall be equal, within agreed upon t
20、oler-ances, to that of a reference sample agreed upon by thepurchaser and the seller.3.5 Oil AbsorptionOil absorption values shall be asagreed upon by the purchaser and the seller.4. Sampling4.1 Two samples, each more than 1 lb (0.45 kg) shall betaken at random from different packages from each lot,
21、 batch,days pack, or other unit of production in a shipment. When nomarkings distinguishing between units of production appear,samples shall be taken from different packages in the ratio oftwo samples for each 5000 kg (10 000 lb), except that forshipments of less than 10 000 lb two samples shall be
22、taken.Atthe option of the purchaser, the samples may be testedseparately, or after blending, in equal quantities, the samplesfrom the same production unit forming a composite sample.Before testing, each of the samples shall be split, and one halfof each may be sealed for referee testing.5.
