Akanyatsonongedzerwa Cotton Iyo yakavanzika yakanatswa cotton iri muchimiro cheupfu, uye saizi yayo yemakumi masere nemakumi mairi mesh uye kuendesa zana muzana. Zvikasadaro, zviri nyore kuti uwedzere pamwe chete panguva yekuita uye kuderedza kunyatsoita kwekuchinja.
Alkalization: Wedzera iyo yakadzora yakanatswa cotton mushure mekuvhurwa Iyo Alkali inoshandiswa muAlkalization is simbi hydroxide kana organic chigadziko. Mari yealkali yakawedzerwa (nehuremu, iyo imwe chete pazasi) ndeye 0.1-0.6 times iyo yakanatswa machira, uye huwandu hwemvura nyoro ndeye 0.3-1 times iyo yekara yakanatswa; Iyo inert solvent isanganiswa yedoro uye hydrocarbon, uye huwandu hweInert solvent yakawedzerwa yakanatswa machira. Nguva dzegumi neshanu: Iyo inert solvent inogonawo kuve doro ne3-5 kabhoni kabhoni maatomu (senge doro, propanh), 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. Kugadziriswa kwekushisa uye nguva kunogona kutsanangurwa maererano nezvinodiwa zvezvinhu uye chigadzirwa.
Eteralization: Mushure mekurapwa kweAlkalization, pasi pePuum mamiriro, erirai inoitwa nekuwedzera iyo yekuwedzera mumiririri, uye iyo yekuzunza mumiririri ari profyle oxide. Kuti uderedze kunwa kwekunyepedzera mumiririri, mune yekutsvagira, iyo itstinging genst nguva. Mushure mekuwedzera iyo yekuzunza mumiririri kekutanga, gadzira tembiricha ye ≤30 ° C for 40-100 ° C yechipiri uye Simudza, nguva inosimudzira ndeye 30-120min, uye ipapo kupisa kusvika? ? ? Ita kuti atsause, iyo nguva iri 1-4h, panguva ino, iyo yakanatswa cotton uye yekuzadzisa mumiririri zvizere kugadzira H-HPC.
Purperization uye kurongedza: Chigadzirwa chakaomeswa chechigadzirwa chazvino chinoburitswa uye chakaburitswa. Saizi yeiyo size yeiyo yakavanzika uye yakafukidzwa chigadzirwa chekugadzira zviripo makumi mana mesh uye kuendesa ndeye 10096, kana maererano nezvinodiwa nevashandisi. Wobva warongedza kunze kwefekitori.
