Ligninndicho chechipiri chinowanikwa patsva muzvarirwo. Inowanikwa muhuwandu hukuru mukupupira tsvina yemvura, iyo shoma shoma inodzokororwa uye kushandiswazve, uye zvimwe zvese zvinoiswa muzvisikwa, zvichikonzera kusvibiswa kwakakomba kwezvakatipoteredza. Munzanga yanhasi, kushomeka kwezvinhu uye kusvibiswa kwemhoteredzo zvazova zvinetso zviviri zvikuru izvo nzanga yevanhu inoda nokukurumidza kugadzirisa. Nekuda kwechimiro chayo chakakosha, lignin yakagadziridzwa uye inoshandiswa sechinhu chakakosha muindasitiri yemakemikari. Iko kusanganiswa kwakakwana kwehutano hwemagariro evanhu uye hupfumi hwave huchiitwa, uye kukunda-kukunda mamiriro ezvinhu akawanikwa.

Chimiro cheligninyakaoma, uye kuchinja kwechimiro chayo kunoenderana nemhando yemiti uye nzira yekuparadzanisa. Naizvozvo, theligninmagadzirirwo emiti yakaoma yakasiyana neiyo yemiti yemichero uye zvirimwa zvegore negore. Zvisinei, nzira dzakasiyana dzekuparadzanisa dzichaguma nemhando dzakasiyana dze lignin. Sulfite pulping inogona kugadzira solublelignosulfonates, uye kraft pulping pasi pemamiriro e-alkaline inogona kuburitsa lignin isinganyunguriki mumvura asi inonyungudika mualkali. Sulfate lignin uye alkali lignin, aya ma lignin ndiwo anonyanya kukonzeresa zvigadzirwa zvemaindasitiri. Pakati pese lignin, sulfate lignin inoonekwa seyakanaka mbishi zvinhu zvekugadzira matanda anonamira.

Chimiro che lignin chine mapoka akawanda anoshanda, uye lignin pachayo uye zvigadzirwa zvayo zvakagadziridzwa zvakashandiswa mune zvakasiyana siyana. Mune simende uye engineering yekuvaka, lignosulfonate inogona kunyatso kuvandudza fluidity yesimende uye ndiyo inonyanya kushandiswa kwekongiri yekuderedza mvura. Parizvino, inenge 50% yaro inobudiswa nekuparadzanisa nzira yekuputika uye kugadzira mapepa.Lignosulfonatesanoshandiswa semendi additives.

Panyaya yefetereza yebiological, iyo lignin chimiro chine zvinhu zvinodiwa pakukura kwechirimwa. Izvi zvinovaka muviri zvinogona kuburitswa zvishoma nezvishoma sezvo lignin pachayo inodzikisira, saka inogona kushandiswa seinodzorwa-inoburitsa inoshanda fetiraiza. Lignin inogona zvakare kusanganiswa nemakemikari nemamorekuru emushonga wezvipembenene kuburikidza nemaitiro akareruka emakemikari, uye inogona kushandiswa semutakuri wezvipembenene zvinononoka kuburitswa, izvo zvinobatsira kuti kurebesa mhedzisiro yekushandiswa kwepesticide, kuitira kuti ikwanise kuwana mhedzisiro yekudzora zvipembenene pasi pe. shoma dosage mamiriro. Kuderedza kusvibiswa kwezvakatipoteredza kunokonzerwa nekushandisa zvisina musoro kwemishonga yezvipembenene uye kuderedza mari yekuisa mishonga yezvipembenene.

Mukurapa kwemvura, maindasitiri akasiyana-siyanaligninuye zvigadzirwa zvavo zvakagadziridzwa zvine yakanaka adsorption zvimiro, kwete chete inogona adsorb simbi ions, asi zvakare inogona kushandiswa adsorb anion, organic uye zvimwe zvinhu mumvura, nekudaro kuchenesa mvura.
