Li-additives tsa lik'hemik'hale bakeng sa slurry ea metsi a mashala ha e le hantle li kenyelletsa li-disperants, stabilizers, defoamers le corrosion inhibitors, empa ka kakaretso li bua ka li-disperants le stabilizers.Sodium lignosulfonateke e 'ngoe ea li-additives bakeng sa slurry ea metsi a mashala.

Melemo ea kopo easodium lignosulfonateka har'a mashala li-additives tsa slurry ke tse latelang:

1. Sodium lignosulphonate e na le phello e ntle ea ho hasana ho feta magnesium lignosulphonate le lignamine, 'me metsi a mashala a lokiselitsoeng a na le metsi a betere. Tekanyo ea lignin ka metsing a mashala a slurry e pakeng tsa 1% - 1.5% (ho ea ka boima ba boima ba metsi a mashala a mashala), e le hore metsi a mashala a nang le motsoako oa 65% a ka lokisoa, a fihle boemong ba khatello e phahameng. seretse sa metsi a mashala.

2. Sodium lignosulfonatee ka fihla ho 50% ea matla a dispersant ea tsamaiso ea naphthalene, kahoo tsamaiso ea naphthalene e hloka 0.5%. Ha ho nahanoa ka theko, ho na le litšenyehelo tse ngata ho sebelisasodium lignosulfonatejoalo ka mohatsela oa seretse sa metsi a mashala.

3. Molemo oa slurry oa metsi a mashala o entsoeng ke dispersant ke hore o na le botsitso bo botle 'me o ke ke oa hlahisa pula e thata ka matsatsi a 3, empa metsi a mashala a mashala a entsoeng ke naphthalene dispersant a tla hlahisa pula e thata ka matsatsi a 3.

4. Sodium lignosulfonatedispersant e ka boela ea sebelisoa hammoho le naphthalene kapa aliphatic dispersant. Karo-karolelano e loketseng ea lignin ho naphthalene dispersant ke 4:1, 'me karolelano e loketseng ea lignin ho aliphatic dispersant ke 3:1. Chelete e khethehileng ea tšebeliso e tla khethoa ho latela mofuta o khethehileng oa mashala le litlhoko tsa nako.

5. Phello ea ho hasana ea lignin dispersant e amana le boleng ba mashala. Ha tekanyo ea metamorphism ea mashala e phahame, mocheso oa mashala o phahame, ho ba le phello e ntle ea ho hasana. Ha boleng ba calorific ba mashala bo le tlase, seretse se eketsehileng, humic acid le litšila tse ling, phello ea ho hasana e mpe le ho feta.
