Kugwiritsa ntchito SDIC popewa kuchepa kwa ubweya

Sodium dichloroisocyanurate(chidule cha SDIC) ndi mtundu umodzi wachlorine mankhwala ophera tizilombo amagwiritsidwa ntchito ngati mankhwala ophera tizilombo toyambitsa matenda, amagwiritsidwa ntchito kwambiri popha tizilombo toyambitsa matenda m'mafakitale, makamaka popha tizilombo toyambitsa matenda m'zimbudzi kapena matanki amadzi. Kuphatikiza pa kugwiritsidwa ntchito ngati mankhwala ophera tizilombo toyambitsa matenda m'mafakitale, SDIC imagwiritsidwanso ntchito kwambiri pochiritsa ubweya wothira shrink komanso kuyeretsa m'makampani opanga nsalu.

Pamwamba pa ulusi waubweya pamakhala mamba ambiri, ndipo pochapa kapena kuumitsa, ulusiwo umalumikizana ndi masikelo amenewa. Popeza kuti mamba amatha kusuntha mbali imodzi, nsaluyo yafota mosasinthika. Ichi ndichifukwa chake nsalu zaubweya ziyenera kuchepetsedwa. Pali mitundu yambiri yosiyanasiyana yochepetsera, koma mfundo ndi yofanana: kuthetsa miyeso ya ubweya wa ubweya.

SDICndi amphamvu oxidizer m'madzi ndi njira yake amadzimadzi akhoza uniformly kumasula hypochlorous asidi, amene interacts ndi mamolekyulu mapuloteni mu ubweya cuticle wosanjikiza, kuswa zomangira mu mamolekyulu ubweya mapuloteni. Chifukwa mamba otuluka amakhala ndi mphamvu zogwira ntchito pamtunda, amakonda kuchita ndi SDIC ndikuchotsedwa. Ubweya waubweya wopanda mamba ukhoza kutsetsereka momasuka ndipo sungathenso kutseka pamodzi, kotero kuti nsaluyo simachepanso kwambiri. Kuphatikiza apo, kugwiritsa ntchito njira ya SDIC pochiza zinthu zaubweya kumathanso kupewa kumamatira pakutsuka ubweya, mwachitsanzo, kuchitika kwa "pilling" chodabwitsa. Ubweya womwe wagwiritsidwa ntchito ndi anti shrink treatment umasonyeza kuti palibe kuchepera ndipo umachapitsidwa ndi makina ndikuthandizira utoto. Ndipo tsopano ubweya waubweya umakhala ndi kuyera kwakukulu komanso kumva bwino kwa manja (ofewa, osalala, zotanuka) komanso kuwala kofewa komanso kowala. Zotsatira zake zimatchedwa mercerization.

Nthawi zambiri, kugwiritsa ntchito njira ya 2% mpaka 3% ya SDIC ndikuwonjezera zina zowonjezera ulusi kapena ulusi wophatikizika wa ubweya ndi nsalu zimatha kuletsa kutulutsa ndi kutulutsa ubweya ndi zinthu zake.

Processing nthawi zambiri ikuchitika motere:

(1) kudyetsa zingwe za ubweya;

(2) Chithandizo cha chlorine pogwiritsa ntchito SDIC ndi sulfuric acid;

(3) Chithandizo cha dechlorination: chithandizo ndi sodium metabisulfite;

(4) Descaling mankhwala: ntchito descaling njira mankhwala, zigawo zikuluzikulu za njira descaling ndi koloko phulusa ndi hydrolytic protease;

(5) Kuyeretsa;

(6) Utomoni mankhwala: ntchito utomoni mankhwala njira mankhwala, mmene utomoni mankhwala njira ndi utomoni mankhwala njira yopangidwa ndi gulu utomoni;

(7) Kufewetsa ndi kuyanika.

Njirayi ndiyosavuta kuwongolera, sizingawononge kuwonongeka kwakukulu kwa fiber, imafupikitsa nthawi yokonza.

Nthawi zambiri ntchito ndi:

pH ya madzi osamba ndi 3.5 mpaka 5.5;

Nthawi yochitira ndi 30 mpaka 90 min;

Mankhwala ena opha ma chlorine, monga trichloroisocyanuric acid, sodium hypochlorite solution ndi chlorosulfuric acid, amathanso kugwiritsidwa ntchito pakuchepa kwa ubweya, koma:

Trichloroisocyanuric acidali ndi kusungunuka kochepa kwambiri, kukonzekera njira yogwirira ntchito ndikugwiritsa ntchito kumakhala kovuta kwambiri.

Sodium hypochlorite solution ndiyosavuta kugwiritsa ntchito, koma imakhala ndi nthawi yayitali. Izi zikutanthauza kuti ngati atasungidwa kwa nthawi ndithu, chlorine yake yogwira ntchito idzatsika kwambiri, zomwe zimapangitsa kuti ndalama ziwonjezeke. Pa sodium hypochlorite solution yomwe yasungidwa kwa nthawi yayitali, chlorine yogwira ntchito iyenera kuyeza musanagwiritse ntchito, apo ayi yankho logwira ntchito la ndende inayake silingakonzekere. Izi zimawonjezera mtengo wantchito. Palibe zovuta zotere mukagulitsa kuti zigwiritsidwe ntchito nthawi yomweyo, koma zimalepheretsa kugwiritsa ntchito kwake.

Chlorosulfonic acid ndi yotakasuka kwambiri, yowopsa, ndi poizoni, imatulutsa utsi mumlengalenga, ndipo ndiyovuta kunyamula, kusunga, ndi kugwiritsa ntchito.
