Kupaka thonje ndi zina za cellulosic fibizi

Scouring ndiye njira yofunika kwambiri yonyowa yomwe imagwiritsidwa ntchito pazinthu za nsalu musanadye kapena kusindikiza.Nthawi zambiri ndi njira yoyeretsera momwe zinthu zakunja kapena zonyansa zimachotsedwa.The scouring ndondomeko, pamene kuyeretsa ndiα- cellulose, imapereka mawonekedwe a hydrophilic ndi permeability kofunikira pazotsatira (kuyeretsa, mercerizing, utoto kapena kusindikiza).Kupukuta bwino ndiye maziko a kumaliza bwino.Kachitidwe ka scouring amayesedwa ndi kusintha kwa wettability wa zinthu zokokoloka.

Makamaka, kuchapa kumachitidwa pofuna kuchotsa mafuta osafunika, mafuta, sera, zonyansa zosungunuka ndi zinyalala zilizonse kapena zolimba zomwe zimamatira kufi.beri, zomwe zikanalepheretsa kuyika, kusindikiza ndi kumaliza.Njirayi imakhala ndi chithandizo ndi sopo kapena chotsukira ndi kapena popanda kuwonjezera alkali.Malingana ndi fibermtundu, alkali akhoza kukhala wofooka (mwachitsanzo soda phulusa) kapena wamphamvu (caustic soda).

Sopo akagwiritsidwa ntchito, madzi ofewa abwino amafunikira.Iyoni yachitsulo (Fe³⁺ndi Ca²⁺) kupezeka m'madzi olimba ndipo pectin ya thonje imatha kupanga sopo wosasungunuka.Vutoli ndi lovuta kwambiri pamene scouring ikuchitika mosalekeza kuphatikizapo kusamba kwa padding komwe chiŵerengero cha mowa chimakhala chochepa kwambiri kusiyana ndi ndondomeko ya batch;mwachitsanzo, Ethylenediaminetetraacetic acid (EDTA), Nitrilotriacetic acid (NTA), etc., angagwiritsidwe ntchito poletsa scum ndi kupanga mafilimu.Chotsukira chopangira chapamwamba kwambiri chimapereka chiwongolero chabwino ndikunyowetsa, kuyeretsa, emulsifying, kubalalika ndi kuchita thovu, motero kumapereka luso loyeretsa bwino.Zotsukira za anionic, zopanda ionic kapena zophatikizira zake, zotsukira zosungunulira ndi sopo zimagwiritsidwa ntchito kwambiri pakukolopa.Pofuna kufulumizitsa ndondomekoyi, nthawi zina amagwiritsidwa ntchito pofuna kunyowetsa pamodzi ndi zosungunulira zotentha kwambiri (cyclohexanol, methylcyclohexanol, etc.)Ntchito ya zosungunulira nthawi zambiri ndikusungunula mafuta osasungunuka ndi sera.

Omanga amawonjezedwa kumadzi owiritsa a kier kuti awonjezere ntchito ya sopo kapena zotsukira.Izi nthawi zambiri zimakhala mchere monga borates, silicates, phosphates, sodium chloride kapena sodium sulphate.Sodium metasilicate (Na₂SiO₃, 5h ndi₂O) amathanso kukhala ngati chotsukira komanso chotchingira.Ntchito ya buffer ndikuyendetsa sopo kuchokera kumadzi kupita ku nsalu / mawonekedwe amadzi ndikuwonjezera kuchuluka kwa sopo pansalu.

Pakuwira thonje ndi caustic soda, mpweya wotsekeka ungayambitse makutidwe ndi okosijeni wa cellulose.Izi zitha kupewedwa powonjezerapo chochepetsera pang'ono monga sodium bisulphite kapena hydrosulphite mu mowa wokolopa.

Njira zopangira zovala zamitundu yosiyanasiyana zimasiyana mosiyanasiyana.Pakati pa ulusi wachilengedweers, thonje yaiwisi imapezeka mu mawonekedwe oyera kwambiri.Kuchuluka kwa zonyansa zomwe ziyenera kuchotsedwa ndizochepera 10% ya kulemera kwake.Komabe, kuwira kwanthawi yayitali ndikofunikira chifukwa thonje lili ndi phula lolemera kwambiri, lomwe ndi lovuta kuchotsa.Mapuloteniwo amakhala m’kati mwa ulusier(lumen) yomwe imakhala yosafikirika ndi mankhwala omwe amagwiritsidwa ntchito popukuta.Mwamwayi mapadi sakhudzidwa ndi chithandizo chanthawi yayitali ndi caustic yankho mpaka ndende ya 2% pakalibe mpweya.Chifukwa chake, ndizotheka kutembenuza zonyansa zonse pakukwapula, kupatula zinthu zachilengedwe, kukhala zosungunuka, zomwe zimatha kutsukidwa ndi madzi.

Kuchuluka kwa cellulosic fibers ena osati thonje ndi losavuta.Bast fibermonga jute ndi fl nkhwangwa sizingawunikidwe mosiyanasiyana chifukwa cha mwayi wochotsa zinthu zingapo zopanda ulusi ndikuwonongeka kwa zinthuzo.Izi nthawi zambiri zimatsukidwa pogwiritsa ntchito sopo kapena detergent pamodzi ndi phulusa la soda.Jute amagwiritsidwa ntchito mobwerezabwereza popanda kuyeretsedwanso, koma nkhwangwa ndi ramie nthawi zambiri zimapetedwa ndipo nthawi zambiri zimawulitsidwa.Jute wopaka utoto amawunikidwa kale koma kuchuluka kwa lignin kumatsalira, zomwe zimapangitsa kuti pakhale kusayenda bwino.

Popeza zonyansa zachilengedwe monga sera ya thonje, zinthu za pectic ndi mapuloteni zimagwirizanitsidwa makamaka mkati mwa khoma loyambirira, ndondomeko yopukuta ikufuna kuchotsa khoma ili.
