Global - Premier Sodium Sulfide: Kiimikada lama huraanka ah ee loogu talagalay dhulalka warshadaha kala duwan
Goobaha Codsiga ee ugu Muhiimsan
Warshadaha warqadda, sodium sulfide-keena wuxuu door muhiim ah ka ciyaaraa habka kraft pulp-ka. Waxay ka caawisaa burburinta lignin, oo ah polymer adag oo dabiici ah oo ku xidha fiilooyinka cellulose ee alwaaxa. Marka la milmo lignin, sodium sulfide wuxuu suurtogaliyaa kala-soocidda cellulose, taas oo ah qaybta ugu weyn ee loo isticmaalo in lagu sameeyo warqadda. Tani waxay keentaa saxar tayo sare leh oo leh xoog iyo dhalaal wanaagsan. Soosaarayaasha warqadda waxay soo saari karaan noocyo badan oo badeecooyin warqad ah, laga bilaabo wargeysyada ilaa waraaqaha daabacaadda ee heerka sare ah, iyagoo isticmaalaya sodium sulfide-keena si kor loogu qaado hufnaanta wax soo saarkooda iyo tayada wax soo saarka.
Warshadaha dharka ayaa sidoo kale si weyn uga faa'iidaysta Global - Premier Sodium Sulfide-keena. Waxaa loo isticmaalaa habka nadiifinta sulfur-ka ee dhogorta. Dhogorta badanaa waxay ka kooban tahay sulfur - oo ka kooban iskudhisyo saameyn kara tayadooda iyo farsamayntooda. Sodium sulfide waxay la falgashaa iskudhisyadan, iyadoo ka saaraysa sulfur-ka oo hagaajinaysa jilicsanaanta, midabka, iyo tayada guud ee dhogorta. Intaa waxaa dheer, waxaa loo isticmaalaa hababka midabaynta qaarkood si loo hagaajiyo deegaanka kiimikada, taasoo sahlaysa qaadashada rinjiga oo wanaagsan oo ay samayso dharka, taasoo horseedaysa midabyo firfircoon oo waara.
Warshadaha macdanta, sodium sulfide waa reagent muhiim ah. Waxaa loo isticmaalaa habka sabbeynta ee macdanta birta qaarkood, gaar ahaan kuwa ka kooban naxaasta, rasaasta, iyo zinc. Sodium sulfide waxay kicin kartaa dusha sare ee macdantan, taasoo ka dhigaysa inay si aad ah u aqbalaan wakiilada ururinta ee loo isticmaalo sabbeynta. Tani waxay si weyn u hagaajineysaa hufnaanta kala soocida macdanta qiimaha leh iyo gangue (dhagaxa qashinka), taasoo kordhineysa heerka soo kabashada biraha qaaliga ah. Shirkadaha macdanta waxay ku tiirsan yihiin sodium sulfide-keena si ay u wanaajiyaan hawlgalladooda farsamaynta macdanta iyo inay kordhiyaan faa'iidadooda.
Warshadaha maqaarka, sodium sulfide-keena waxaa loo isticmaalaa habka timaha looga saaro. Waxay ka caawisaa milmida borotiinka ku jira timaha iyo lakabka maqaarka xayawaanka, taasoo sahlaysa in timaha laga saaro. Tani waa tallaabo muhiim ah oo ku saabsan wax soo saarka maqaarka maadaama ay u diyaarinayso maqaarka si loo sii farsameeyo. Iyagoo isticmaalaya sodium sulfide-keena tayada sare leh, soosaarayaasha maqaarku waxay soo saari karaan maqaar leh dusha sare oo siman iyo qaab-dhismeed wanaagsan, iyagoo buuxinaya heerarka sare ee suuqa maqaarka adduunka.
