Lub ntsiab ntawm talc yog hydrotalcite hydrous magnesium silicate nrog cov mis molecular ntawm mg3 [si4o10] (OH) 2. Talc belongs rau monoclinic system.Cov siv lead ua yog pseudohexagonal lossis rhombic, qee zaus.Lawv feem ntau yog tuab loj, nplooj, radial thiab fibrous aggregates.Nws yog xim tsis muaj xim thiab pob tshab los yog dawb, tab sis nws yog lub teeb ntsuab, lub teeb daj, lub teeb xim av los yog lub teeb liab vim yog me me ntawm impurities;lub cleavage nto yog pearl luster.Hardness 1, tshwj xeeb gravity 2.7-2.8.
talc hmoov muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg xws li lubricity, hluav taws kub, acid tsis kam, rwb thaiv tsev, siab melting point, chemical inactivity, zoo npog lub hwj chim, softness, zoo luster, muaj zog adsorption, thiab lwm yam vim hais tias cov crystal qauv ntawm talc yog txheej, nws muaj qhov nyiam ntawm kev sib cais yooj yim rau hauv nplai thiab tshwj xeeb lubricity.Yog tias cov ntsiab lus ntawm Fe2O3 siab heev, nws cov rwb thaiv tsev yuav raug txo.
Kev siv talc:
(1) Tshuaj pleev ib ce qib (Hz): siv rau txhua yam moisturizing hmoov, zoo nkauj hmoov, talcum hmoov, thiab lwm yam.
(2) Tshuaj zaub mov qib (YS): tshuaj ntsiav tshuaj, qab zib txheej, prickly tshav kub hmoov, tshuaj suav tshuaj, zaub mov additive, cais tus neeg sawv cev, thiab lwm yam.
(3) Txheej qib (TL): siv rau cov xim dawb lub cev thiab txhua yam dej-raws li, roj-raws li, resin industrial coatings, primer, tiv thaiv xim, thiab lwm yam.
(4) Ntawv qib (zz): siv los ua cov khoom ntim rau txhua yam ntawm cov ntawv thiab cov ntawv ntawv, tus neeg saib xyuas ntoo asphalt.
(5) Yas qib (SL): siv los ua cov khoom siv rau polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene, polyester thiab lwm yam yas.
(6) Roj Hmab qib (AJ): siv rau roj hmab muab tub lim thiab tiv thaiv adhesion tus neeg sawv cev ntawm cov khoom siv roj hmab.
