I-barium sulfate evundile iyisithako esisebenza kahle kakhulu esingenazinto eziphilayo kanye nombala wokwandisa owenziwe ngokusabela kwamakhemikhali. Ingenye yezinto zokusetshenziswa ezingaphili ezisetshenziswa kakhulu emhlabeni jikelele, ilandela kuphela i-titanium dioxide kanye nombala we-iron oxide. Njengesithako esimhlophe esingenazinto eziphilayo kanye nokugcwalisa, iyinto ebalulekile yokwakha izinto zokwakha, ukumbozwa, amapulasitiki, irabha, uyinki kanye nezimboni zokwenza amaphepha. Inezinzuzo eziyinhloko njengokuphepha kwemvelo, ubumhlophe obukhulu, ukumelana nesimo sezulu, ukumelana ne-asidi kanye ne-alkali, kanye nokusebenza kahle kwezindleko. Iqukethe usayizi wezinhlayiya ezincane kakhulu, ukumuncwa kwamafutha okuphansi kanye nokuzinza kwamakhemikhali okuhle kakhulu, njengezinto zokusetshenziswa ezibalulekile zokukhiqiza izimboni eziphezulu.

1. Ubuciko obuhle: Izindlela ezimbili zokukhiqiza ziqinisekisa ikhwalithi elawulekayo nelandelekayo

(1)Ukucutshungulwa kwamaminerali kwemvelo

Ihlanzwa futhi icutshungulwe kusuka ku-ore ye-barite yemvelo ngokuchoboza, ukugaya, ukuntanta kanye nokususa ukungcola, ukugcina ukuqina kwamaminerali emvelo, ngezindleko ezingabizi. Ifanele izimo ezijwayelekile ezinezidingo eziphezulu zokusebenza kahle, njengezinto zokwakha ezivamile, izembozo zezinga eliphansi kanye nokugcwaliswa kwepulasitiki okuvamile.

(2)Ukwenziwa kwamakhemikhali

Kusetshenziswa izinqubo ezinembile njengokunisela ngamakhemikhali, ukuhlunga, ukuwasha, ukomisa kanye nokugaya kahle kakhulu. Izinto zokusetshenziswa zingasebenzisa imikhiqizo engaphansi kwezimboni ukuze kufezwe ukuguqulwa "kokungcola kube yingcebo", okuhambisana nemikhuba yokukhiqiza eluhlaza. Imikhiqizo eyenziwe ikhombisa ubumsulwa obuphezulu, usayizi wezinhlayiya ezifanayo, ubumhlophe obuphezulu kanye nokusebenza okuqinile, ihlangabezana nezidingo eziqinile zezingubo zokugqoka eziphezulu, izinto zokuxhumana nokudla, izinto zokwelapha kanye nepulasitiki yezinga eliphezulu.

2. Izici Eziyinhloko: Izinzuzo Eziyisithupha Ezinkulu Zisekela “Inani Eliningi”

(1)Inobungani nemvelo futhi ayinabo ubuthi, iyahambisana nemithetho futhi ayikhathazeki

Ayinazo izinsimbi ezisindayo nezinto eziyingozi, ihambisana nezindinganiso ze-EU REACH, i-RoHS kanye nezindinganiso zezwe laseShayina, ifanele ukusetshenziswa kumathoyizi ezingane, izimonyo, izinto zokuxhumana nokudla, imikhiqizo yezokwelapha neyepulasitiki yansuku zonke.

(2)Ayimelani nesimo sezulu futhi ayisheshi, ihlala isikhathi eside futhi izinzile

Imelana ne-UV enamandla kakhulu kanye nokumelana nokuguga, ngeke iphuzi, ifiphale noma ishoki iminyaka eminingi yokusetshenziswa ngaphandle, ifanelekela izindawo ezinemvula eshisayo nenomswakama, okwenza kube “ukugcwalisa isikhathi eside” kwezakhiwo zangaphandle kanye nezingubo zangaphandle.

(3)Ukumelana ne-asidi kanye ne-alkali kanye nokumelana nokugqwala

Ukumelana okuvelele kwe-asidi ne-alkali, okuhambisana kahle nezinhlelo zesimende ne-lime; kuzinzile ekugqwaleni kwamakhemikhali aqinile e-asidi, i-alkali kanye nezimboni, okwenza kube ukukhetha kokuqala kokumbozwa kokugqwala kanye nezinto zobunjiniyela bamakhemikhali.

(4)Ubumhlophe obuphezulu kanye namandla amahle okufihla

Ubumhlophe obuphezulu kanye nokuthungwa okuhle, kanye nokusebenza kahle kokugcwalisa. Inani elincane lingathuthukisa ukugcwala kwesembozo kanye nomphumela wokumboza, lithathe indawo yengxenye ye-titanium dioxide ngempumelelo, linciphise izindleko zezinto futhi lenze ngcono ukusebenza kahle kwezindleko.

(5)Ukuhlakazeka okuhle kanye nokwakhiwa okulula

Impuphu ecolekile kakhulu, ehlakazeka kalula ngokulinganayo ezinhlelweni ezisekelwe emanzini kanye nezinyibilikisi, ifanelekela amasu ahlukahlukene okucubungula njengezembozo, ukhonkolo, amapulasitiki, irabha kanye nokukhiqizwa kweyinki.

(6)Ukuqina kweqembu kanye nekhwalithi elawulekayo

Abakhiqizi abadumile basebenzisa uhlelo lokuphatha ikhwalithi lwe-ISO 9001, baqinisekisa ubumhlophe obuhambisanayo, usayizi wezinhlayiya kanye nokusebenza kahle eqoqweni ngalinye, begwema ukulahlekelwa kokukhiqiza okubangelwa umehluko wombala kanye nekhwalithi engazinzile.

3. Ukunika amandla zonke izimboni: Kusukela ezintweni zokwakha eziyisisekelo kuya ekukhiqizeni okusezingeni eliphezulu, okuhlanganisa yonke imikhakha

(1)Imboni Yezinto Zokwakha

Ukhonkolo onemibala, amathayela aphansi, amathayela ophahla: Thuthukisa ukuqina nokumelana nesimo sezulu, gcina umbala ozinzile isikhathi eside elangeni nasemvuleni; Ukwembozwa kodonga lwangaphakathi nolwangaphandle, i-putty: Ubumhlophe obuphezulu, ukusebenza kahle kokugcwalisa, okunobungani nemvelo futhi okumelana nokuqhekeka ngemva kokwakhiwa; Imigwaqo nengqalasizinda: Kusetshenziswa ezimbozweni zethrafikhi nezinto ezingagugi ukuze kuthuthukiswe ukumelana nokuguga nokuqina kwesakhiwo.

(2)Imboni Yepulasitiki Nerabha

Amapayipi, amathoyizi, izintambo, izithende zezicathulo: Amelana nokushisa okuphezulu, aziguquguquki ngobukhulu, zihlangabezana nezindinganiso zokuvikela imvelo, zifanele imikhiqizo yepulasitiki yezinga eliphezulu kanye nezesekeli zerabha.

(3)Izembozo Zezimboni Nokuvikelwa Kokugqwala

Upende wezimoto kanye nopende wezimboni: Kusetshenziswa njengezinto zokugcwalisa nokuqeda ukuguga ukuze kuthuthukiswe ubulukhuni nokuqina kopende; Ukwakha imikhumbi, amabhuloho, kanye nezakhiwo zensimbi: Ukugcwalisa okuyinhloko kopende olulwa nokugqwala ukuze kumelwane nomoya wolwandle kanye nokuguguleka komswakama futhi kwandise isikhathi senkonzo.
