Sodium dichloroisocyanurate(kupfupisa SDIC) imwe mhando yechlorine chemical disinfectant chinowanzo shandiswa semushonga wekuuraya utachiona hwekuita sterilization, inoshandiswa zvakanyanya mumaindasitiri ekuuraya utachiona, kunyanya mukuuraya utachiona hwetsvina kana matangi emvura. Pamusoro pekushandiswa semushonga wekuuraya hutachiona hwemaindasitiri deodorant, SDIC zvakare inowanzoshandiswa mushinda yeshinda anti shrink kurapwa uye bleaching muindasitiri yemachira.
Pane zvikero zvakawanda pamusoro peshinda dzemakushe, uye panguva yekugezwa kana kuomeswa, shinda dzinovharirana pamwe chete nezvikero izvi. Sezvo zvikero zvinongofamba munzira imwe chete, jira rakadzikira zvisingachinjiki. Ichi ndicho chikonzero machira emvere dzemakwai anofanirwa kuderedzwa. Kune marudzi akasiyana-siyana e-shrink-proofing, asi nheyo yacho yakafanana: kubvisa zviyero zvefiber yemvere.
SDICis oxidizer yakasimba mumvura uye mhinduro yayo ine aqueous inogona kuburitsa zvakafanana hypochlorous acid, iyo inopindirana nemapuroteni mamorekuru mumvere dzemakwai cuticle layer, ichityora zvimwe zvisungo mumaprotein molecules. Nekuti zvikero zvakabudikira zvine simba rekuita basa repamusoro, ivo vanofarira kuita neSDIC uye vanobviswa. Faibha dzemakushe dzisina zvikero dzinogona kutsvedza zvakasununguka uye hadzichakiyi pamwe chete, saka jira harichadzikire zvakanyanya. Mukuwedzera, kushandisa SDIC mhinduro yekurapa mvere dzemakwai kunogonawo kudzivirira kunamatira panguva yekugeza mvere, kureva kuitika kwe "pilling" chiitiko. Iwo makushe akaitwa anti shrink treatment anoratidza kunenge asina shrinkage uye anogezwa nemuchina uye anobatsira kudhaya. Uye ikozvino mvere dzemakwai dzine kuchena kwepamusoro uye kunzwa kwakanaka kwemaoko (yakapfava, yakapfava, elastic) uye yakapfava uye yakajeka kupenya. Mhedzisiro yacho inonzi mercerization.
Kazhinji, kushandisa 2% kusvika 3% mhinduro yeSDIC nekuwedzera zvimwe zvinowedzerwa pakumisa mvere dzemakwai kana mvere dzakasanganiswa faibha nemachira zvinogona kudzivirira kupfava nekunzwa kwemvere dzemakwai nezvigadzirwa zvawo.
Iyo processing inowanzoitwa sezvinotevera:
(1) kudyisa shinda dzemvere;
(2) Chlorination kurapwa nekushandisa SDIC uye sulfuric acid;
(3) Dechlorination kurapwa: kurapwa ne sodium metabisulfite;
(4) Descaling treatment: kushandisa descaling solution yekurapa, iyo mikuru ye descaling solution is soda ash uye hydrolytic protease;
(5) Kuchenesa;
(6) Resin kurapwa: kushandisa resin kurapwa mhinduro yekurapa, umo resin kurapwa mhinduro iri resin kurapwa mhinduro inoumbwa necomposite resin;
(7) Kupfava uye kuomesa.
Iyi nzira iri nyore kudzora, haizokonzeri yakawandisa fiber kukuvara, inonyatso kupfupisa nguva yekugadzirisa.
Mamiriro ekushanda akajairika ndeaya:
Iyo pH yekugezera mhinduro ndeye 3.5 kusvika 5.5;
Nguva yekuita ndeye 30 kusvika ku90 min;
Mamwe ma chlorine disinfectants, akadai se trichloroisocyanuric acid, sodium hypochlorite solution uye chlorosulfuric acid, anogonawo kushandiswa pakudonha kwemvere, asi:
Trichloroisocyanuric acidine yakaderera solubility, kugadzirira kushanda mhinduro uye kushandisa kunonetsa zvikuru.
Sodium hypochlorite mhinduro iri nyore kushandisa, asi ine hupenyu hupfupi hwesherufu. Izvi zvinoreva kuti kana yakachengetwa kwenguva yakati, chlorine yayo inoshanda inodonha zvakanyanya, zvichikonzera kuwedzera kwemitengo. Kune sodium hypochlorite mhinduro iyo yakachengetwa kwenguva yakati, iyo inoshanda yeklorini yemukati inofanirwa kuyerwa isati yashandiswa, kana zvisina kudaro mhinduro yekushanda yeimwe yakasungwa haigone kugadzirirwa. Izvi zvinowedzera mari yevashandi. Iko hakuna matambudziko akadaro kana uchiitengesa kuti ishandiswe pakarepo, asi inogadzirisa zvakanyanya kushandiswa kwayo.
Chlorosulfonic acid inoshanda zvakanyanya, ine njodzi, ine muchetura, inoburitsa utsi mumhepo, uye haiite kutakura, kuchengeta, uye kushandisa.
