Umgubo weTalc kunye nomgubo weWollastonite ziiminerali ezimbini ezisetyenziswa kakhulu kwishishini lanamhlanje. Zabelana ngamacandelo okusetyenziswa ahambelanayo kunye nokusebenza okuncinci, kodwa zinezakhiwo zomzimba ezahlukeneyo, iipropati zeekhemikhali kunye neemeko ezifanelekileyo, zenza ubudlelwane bokhuphiswano kunye nobongezelelweyo kwimarike yezinto ezikrwada zehlabathi.

Ngokuphathelele ukufana, zombini ezi zimbiwa zimhlophe kakhulu, zineempawu zeekhemikhali ezizinzileyo kunye netyhefu ephantsi. Zisetyenziswa rhoqo njengezizalisi ezisebenzayo ezingabizi kakhulu ukuze zithathe indawo yezinto eziluhlaza ezibizayo zeekhemikhali, zinciphise ngempumelelo iindleko zokuvelisa iimveliso ezisezantsi. Zombini ezi zinto zinokunyusa ubulukhuni, ukumelana nemozulu kunye nokuguda komphezulu weempahla ezigqityiweyo, kwaye zamkelwe kakhulu kwiiplastiki, kwiingubo, kwiiseramikhi, kwiirabha nakwiimveliso zezinto zokwakha. Ukongeza, ziyahambelana nemigangatho yemveliso eluhlaza yehlabathi, zithatha indawo kancinci kancinci izinto ezinobungozi ze-asbestos kwaye zifumana ukwamkelwa okuzinzileyo kwimarike.

Nangona kunjalo, kukho umahluko ocacileyo phakathi kwezi powder zimbini zezimbiwa. Ngokwesakhiwo, i-talc inesimo se-lamellar ngelixa i-wollastonite inesimo sekristale esicacileyo. I-Talc inesimo sokuthambisa esigqwesileyo, ukuthamba kunye nokusebenza kakuhle kobushushu, okwenza ukuba ilungele izinto zokuthambisa, izixhobo zamayeza kunye neemveliso zeplastiki ezikhazimlayo. I-Wollastonite inamandla abalaseleyo oomatshini, uzinzo lobushushu kunye nomthamo wokulwa nokuqhekeka, isebenza ngcono kwi-ceramics zokutshisa ezishushu kakhulu kunye nezixhobo zokwakha ezinamandla aphezulu.

Ngokwekhemikhali, i-talc yi-magnesium silicate ene-asidi enamandla kunye nokumelana ne-alkali. I-Wollastonite ikwi-calcium silicate, enomsebenzi ongcono wokusila kunye nefuthe lokujika. Xa isetyenziswa ngokwenene, i-talc ithandwa kakhulu ngenxa yokuthamba okuthambileyo kunye neemfuno zokuthambisa, ngelixa i-wollastonite ibalaseleyo kwiimeko zokuqinisa kunye nokumelana nobushushu obuphezulu.

Kwicandelo lemizi-mveliso, ezi mpuphu zimbini zinokuthathelwa indawo ngokuyinxenye kwaye zongezane. Abavelisi bakhetha izixhobo ezifanelekileyo ngokweemfuno zokusebenza kwemveliso. Ngokuphuculwa okuqhubekayo kwamashishini asezantsi, zombini iimpuphu ze-talc kunye ne-wollastonite zigcina imfuno yemarike ezinzileyo. Iingenelo zazo ezahlukeneyo ziya kwandisa ngakumbi imida yokusetyenziswa kwazo, ziqhubele phambili kunye nophuhliso oluzinzileyo lweshishini lehlabathi lokuzalisa izimbiwa ezingezizo ezesinyithi.
