Nilai panyerepan lenga bubuk talc minangka indeks teknis penting, sing nuduhake kemampuan nyerep bubuk talc dadi lenga. Ukuran nilai panyerepan lenga langsung mengaruhi efek aplikasi bubuk talc ing lapangan industri beda. Biasane, nilai panyerepan lenga bubuk talc langsung ana hubungane karo kehalusan, lan kehalusan sing luwih apik, sing luwih dhuwur panyerepan lenga 10. Ing aplikasi praktis, nilai panyerepan lenga talc bisa mbantu prédhiksi lan ngontrol kinerja produk, kayata ing industri pelapis lan plastik, ing endi nilai panyerepan lenga mengaruhi aliran lan kinerja pangolahan produk.
Talc nduweni sifat fisik lan kimia sing apik kayata lubricity, resistance viskositas, bantuan aliran, tahan geni, tahan asam, insulasi, titik leleh dhuwur, ora aktif kimia, daya tutup sing apik, alus, luster apik, pasukan adsorpsi sing kuat, lan liya-liyane. Yen kandungan Fe2O3 dhuwur banget, bakal nyuda insulasi.
Talc is soft, its Mohs hardness coefficient is 1~1.5, slippery feeling, {001} cleavage is complete, easy to split into flakes, natural resting Angle is small (35°~40°), extremely unstable, surrounding rock is silicified and slippery magnesite, magnesite, lean ore or dolomitic marble, except a few moderately stable, generally unstable, joints, cracks development, The physical and mechanical properties of ore and surrounding rock have great influence on mining technology.
