Focus on Cellulose ethers

Cellulose ether classification kodhi uye hunyanzvi zvinodiwa

Cellulose ndiyo yakanyanya kuwanda organic renewable sosi munyika. Inobva kune yakasvibira yepasi uye yepasi pemvura zvidyarwa uye ndicho chinhu chikuru chechirimwa fiber cell madziro. Kunze kwehuwandu hudiki hwebhakitiriya hwemhuka uye zvipenyu zvepasi pegungwa, cellulose inonyanya kuwanikwa mumiti yakasvibira. Kuburikidza nephotosynthesis, zvidyarwa zvinogona kubatanidza 155Gt cellulose pagore, iyo 150Mt inobva kumiti yepamusoro; huni pulp cellulose inenge 10Mt; donje cellulose 12Mt; kemikari (giredhi) 7Mt ye cellulose, nepo huni hwakawanda (inenge 500Mt ye cellulose) ichiri kushandiswa sehuni kana jira.
Natural cellulose inosiyana mukuchena. Cotton ndiyo fiber yechirimwa ine yakanyanya cellulose yemukati mune zvakasikwa, uye iyo cellulose yemukati inowanzova pamusoro pe95%. Cotton refu staples anowanzo shandiswa mukugadzira machira. Iyo pfupi fiber inodaidzwa kuti Linter pulp, inova yakakosha zvinhu zvekugadzira maindasitiri ezvigadzirwa zve cellulose.
