Umhlaba wonkhe - I-Sodium Sulfide Leyinhloko: Ikhemikhali Lebalulekile Yetindzawo Letehlukahlukene Tetimboni
Tindzawo Letinkhulu Tesicelo
Embonini yemaphepha, i-sodium sulfide yetfu idlala indzima lebalulekile enchubeni yekukhicita i-kraft. Kuyasita ekuphuleni lignin, i-polymer leyinkimbinkimbi lebopha imicu ye cellulose etigodvweni. Ngekuncibilikisa i-lignin, i-sodium sulfide yenta kutsi kuhlukaniswe i-cellulose, lokuyintfo lebalulekile lesetjentiswa kwenta liphepha. Loku kuphumela ku pulp lesetulu - lesezingeni leliphakeme lenemandla laphucukile kanye nekukhanya. Bakhiciti bemaphepha bangakhicita imikhicito leyehlukahlukene yemaphepha, kusuka kumaphephandzaba kuya kumaphepha ekushicilela lasetulu, basebentisa i-sodium sulfide yetfu kwenta ncono kusebenta kwabo kwekukhicita kanye nelizinga lemkhicito.
Imboni yetindvwangu nayo iyazuza kakhulu ku-Sodium Sulfide yetfu yeMhlaba wonkhe - Ndvunankhulu. Isetjentiswa enqubweni desulfurization uboya. Uboya buvame kuba ne sulphur - lenetintfo letihlangene letingatsintsa lizinga layo kanye nekucubungula. iSodium sulfide ihlangana naletinhlanganisela, isusa isulphur futsi yente ncono kutsamba, umbala, kanye nelizinga lonkhe leboya. Ngekwengeta, isetjentiswa kuletinye tindlela tekudaya kwentela kulungisa simo semakhemikhali, kwenta kutsi kube nekutsatfwa kwedayi lokuncono ngulendvwangu, lokuholela ekubeni nemibala lephilako nalehlala sikhatsi lesidze.
Embonini yetimayini, i-sodium sulfide yintfo lebalulekile. Isetjentiswa enchubeni yekuntanta kwetinsimbi letitsite, ikakhulukati leto letinelitfusi, umthofu, ne-zinc. iSodium sulfide ingasebenta etulu kwalama ores, kwenta kutsi emukele kakhulu ema ejenti ekubutsela ndzawonye lasetjentiswa ekuntanta. Loku kwenta ncono kakhulu kusebenta kahle kwekuhlukanisa emaminerals labalulekile kusuka ku gangue (lidvwala lelilahliwe), kukhulisa lizinga lekubuyiswa kwetinsimbi letiligugu. Tinkampani tetimayini tetsembele ku-sodium sulfide yetfu kute tikhulise imisebenti yato yekucubungula i-ore - futsi tikhulise inzuzo yato.
Embonini yesikhumba, i-sodium sulfide yetfu isetjentiswa enchubeni yekungabi netinwele. Kuyasita kuncibilikisa emaprotein etinweleni kanye ne epidermis yetikhumba tetilwane, kwenta kubelula kususa tinwele. Lesi sinyatselo lesibalulekile ekukhiciteni sikhumba njengoba silungiselela sikhumba kutsi sichubeke sisetjentwe. Ngekusebentisa i-sodium sulfide yetfu lesesigabeni lesiphakeme, bakhiciti besikhumba bangakhicita sikhumba lesinendzawo lebushelelezi kanye nekubukeka lokuncono, bahlangabetana nemazinga laphakeme emakethe yesikhumba yemhlaba wonkhe.

Ngalokufishane
I-Sodium Sulfide yetfu yemhlaba wonkhe - Premier ipakishwe etitjani letisezingeni lelisetulu, letingangeni umoya kuvikela i-oxidation kanye nekucinisekisa kusimama kwayo ngesikhatsi sekugcina kanye nekutfutsa. Sicumbi ngasinye sidlula etinyatselweni leticinile tekulawula lizinga, kufaka ekhatsi kuhlolwa kwebumsulwa, kuhlatiya emakhemikhali, kanye nekuhlolwa kwekusebenta. Noma ngabe ungumshini wekugaya emaphepha eNyakatfo Melika, imboni yetindvwangu e-Asia, inkampani yetimayini e-Australia, noma indzawo yekushuka sikhumba eYurophu, i-sodium sulfide yetfu sisombululo lesetsembekile nalesigucugucukako losidzingako. Iniketa kusebenta lokungeke kwehlulwe, kucinisekisa kutsi ihlangabetana futsi idlula tidzingo takho letitsite temboni.
