Yakanyatsonongedzerwa Cotton Iyo yakanatswa yakanatswa cotton iri muchimiro cheupfu, nehukuru hwechikamu che80 mesh uye kuendesa kwe100%. Zvikasadaro, zviri nyore kune coalesce pamwechete panguva yekuita uye kuderedza kunyatsoita kwekuchinja.
Alkalization: Wedzera iyo yakacheneswa yakanatswa yekotoni yekuvhura kune iyo Inert Solvent, uye Mvura yakapfava yekuzvimba zvekotoni kuti ifambise mamaira ezasi uye kugadzirisa kufanana kwekuchinja kwetsika. Iyo alkali inoshandiswa kune alkalization is simbi hydroxide kana organic alkali. Mari yeAlkali yakawedzerwa (nehuremu, iyo pazasi) ndeye 0.1-0.6 times iyo yakanatswa Cotton, huwandu hwemvura nyoro hunowedzerwa ndeye 0.3-1.0 times iyo yekara yakanatswa; Iyo inert solvent isanganiswa yedoro uye hydrocarbon, uye huwandu hweInert solvent yakawedzerwa ndeye 0.3-1.0 times iyo yekotoni yakanatswa. 7 -15 times of: Iyo inert solvent inogonawo kuve doro ne3-5 kabhoni kabhoni maatomu (senge doro, propanol), acetone. Inogona zvakare kuve aliphatic hydrocarbons uye inonhuhwirira hydrocarbons; Tembiricha inofanirwa kudzorwa mukati me0-4 ° C panguva yeayo; Nguva yea alkalization iri anenge 1hr. Iko kugadziridzwa kwekushisa uye nguva kunogona kutsanangurwa maererano nezvinodiwa nezvinodiwa nezvinodiwa.
Kuwedzera: Mushure mekurapwa kweAlkalization, pasi peVafuum mamiriro, etera mumiririri anowedzerwa kuti atsauke, uye itstitification mumiririri ari profyleo oxide. Kuti uderedze kudhinda kwekuchinja kwemirimo, panguva yekuwedzera, iyo yekuwedzera mumiririri inowedzerwa ndeye 1-3. nguva. Mushure mekuwedzera gadziriso yekuzadzisa kekutanga, sm ? ? Ita kuti aze itsera, nguva iri 1-4h, panguva ino, iyo cotton yakanatswa inoshanda zvizere neiyo etera
Kupwanya uye kurongedza: Kupwanya uye Kushambadzira Chigadzirwa chakaomeswa chechinhu chazvino Wobva warongedza fekitori
