Lignin ke ea bobeli ka mor'a cellulose libakeng tsa polokelo ea tlhaho, 'me e nchafatsoa ka tekanyo ea lithane tse limilione tse likete tse 50 selemo se seng le se seng. Indasteri ea makhasi le pampiri e arola lithane tse ka bang limilione tse 140 tsa selulose ho limela selemo se seng le se seng, 'me e fumana lithane tse ka bang limilione tse 50 tsa lihlahisoa tsa lignin, empa ho fihlela joale, ho feta 95% ea lignin e ntse e tšeloa ka ho toba linōkeng kapa linōkeng e le " joala bo botšo”. Ka mor'a ho kenngoa, e chesoa 'me e sebelisoa ka seoelo ka katleho. Ho fokotseha ho ntseng ho eketseha ha matla a mesaletsa ea lintho tsa khale, mehloli e mengata ea lignin, le tsoelo-pele e potlakileng ea mahlale a lignin li tiisa tsoelo-pele e tsitsitseng ea melemo ea moruo ea lignin.

Litsenyehelo tsa lignin li tlase, 'me lignin le lihlahisoa tsa eona li na le mesebetsi e sa tšoaneng, e ka sebelisoang e le li-dispersants, adsorbents / desorbers, lithuso tsa ho hlaphoheloa ha petroleum, le li-emulsifiers tsa asphalt. Tlatsetso ea bohlokoa ka ho fetisisa ea lignin ntlafatsong ea moshoelella ea batho e ho Fana ka mohloli o tsitsitseng le o tsoelang pele oa lintho tse phelang, 'me tebello ea ts'ebeliso ea eona e pharaletseng haholo. Ithute kamano pakeng tsa thepa ea lignin le sebopeho, 'me u sebelise lignin ho etsa lipolymer tse senyehang le tse nchafalitsoeng. Thepa ea physicochemical, thepa ea ts'ebetso le theknoloji ea lignin e fetohile litšitiso ho lipatlisiso tsa hajoale ka lignin.

Lignin sulfonate e entsoe ka thepa e tala ea sulfite wood pulp lignin ka ho tsepamisa mohopolo, ho nkela sebaka, oxidation, filtration le ho omisa. Chromium lignosulfonate ha e na phello feela ea ho fokotsa tahlehelo ea metsi, empa hape e na le phello ea diluting. Ka nako e ts'oanang, e boetse e na le litšobotsi tsa ho hanyetsa letsoai, ho hanyetsa mocheso o phahameng le ho lumellana hantle. Ke mokelikeli o nang le khanyetso e matla ea letsoai, khanyetso ea khalsiamo le ho hanyetsa mocheso. Lihlahisoa li sebelisoa haholo metsing a hloekileng, metsing a leoatle, le li-slurries tsa samente tse tletseng letsoai, liretse tse fapa-fapaneng tse tšetsoeng ka calcium le seretse se tebileng sa liliba, se ka khonang ho tsitsisa lebota la seliba le ho fokotsa viscosity le ho kuta ha seretse.

Lipontšo tsa 'mele le tsa lik'hemik'hale tsa lignosulfonate:

1. Ts'ebetso e lula e sa fetohe ho 150 ~ 160 ℃ ka lihora tse 16;

2. Ts'ebetso ea 2% ea letsoai la samente slurry e molemo ho feta ea tšepe-chromium lignosulfonate;

3. E na le matla a matla a anti-electrolyte 'me e loketse mefuta eohle ea seretse.

Sehlahisoa sena se phuthetsoe ka mokotleng o lohiloeng o kentsoeng ka mokotla oa polasetiki, o nang le boima ba lik'hilograma tse 25, 'me mokotla oa mokotla o tšoauoa ka lebitso la sehlahisoa, letšoao la khoebo, boima ba sehlahisoa, moetsi le mantsoe a mang. Lihlahisoa li lokela ho bolokoa ka tlung ea polokelo ho thibela mongobo.
