Ingxenye eyinhloko ye-talc yi-hydrotalcite hydrous magnesium silicate enefomula yama-molecule ye-mg3 [si4o10] (OH) 2. I-Talc ingeyesistimu ye-monoclinic. I-crystal i-pseudohexagonal noma i-rhombic, ngezinye izikhathi. Ngokuvamile iba yi-aggregates enkulu kakhulu, enamaqabunga, ene-radial kanye ne-fibrous. Ayinambala futhi icacile noma imhlophe, kodwa iluhlaza okotshani, iphuzi elikhanyayo, insundu elikhanyayo noma ngisho nebomvu elikhanyayo ngenxa yenani elincane lokungcola; ubuso bokuqhekeka bucwebezela ngamaparele. Ubulukhuni 1, amandla adonsela phansi athile 2.7-2.8.

Impuphu ye-talc inezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali ezifana nokuthambisa, ukumelana nomlilo, ukumelana ne-asidi, ukufudumala, iphuzu lokuncibilika eliphezulu, ukungasebenzi kwamakhemikhali, amandla amahle okumboza, ubumnene, ukukhanya okuhle, ukumuncwa okunamandla, njll. ngoba isakhiwo sekristalu se-talc sinezingqimba, sinomkhuba wokuqhekeka kalula sibe yizikali kanye nokuthambisa okukhethekile. Uma okuqukethwe yi-Fe2O3 kuphezulu kakhulu, ukufudumala kwayo kuzoncishiswa.

Ukusetshenziswa kwe-talc:

(1) Izimonyo zebanga (Hz): lisetshenziselwa zonke izinhlobo zempuphu yokuthambisa, impuphu yobuhle, impuphu ye-talcum, njll.

(2) Ibanga lokudla kwemithi (YS): ithebhulethi yemithi, uqweqwe lukashukela, impuphu yokushisa ehlabayo, umuthi kadokotela waseShayina, isithasiselo sokudla, i-ejenti yokuzihlukanisa, njll.

(3) Ibanga lokumboza (TL): elisetshenziselwa umbala omhlophe womzimba kanye nazo zonke izinhlobo zokumboza kwezimboni okusekelwe emanzini, okusekelwe ku-oyili, i-resin, i-primer, upende ovikelayo, njll.

(4) Ibanga lephepha (zz): lisetshenziswa njengesigcwalisi sazo zonke izinhlobo zephepha nebhodi lephepha, i-ejenti yokulawula i-asphalt yokhuni.

(5) Ibanga lepulasitiki (SL): lisetshenziswa njengesigcwalisi se-polypropylene, i-nylon, i-polyvinyl chloride, i-polyethylene, i-polystyrene, i-polyester kanye nezinye ipulasitiki.

(6) Ibanga lerabha (AJ): lisetshenziselwa ukugcwalisa irabha kanye ne-anti-adhesive agent yemikhiqizo yerabha.
