Chii chinonzi Thiourea Dioxide?
Thiourea dioxide (TDO, formamidine sulfin acid) chinhu chinobvisa tsvina chakasimba, chakagadzirwa nesarufa, chinogara kwenguva refu kana chakachengetwa uye chisinganyanyi kubatwa nehunyoro kupfuura sodium dithionite. Mumvura inodziya kana tembiricha yakakwira uye alkaline pH, TDO inoora kuti ibudise mhando dzine simba dzinobvisa tsvina dzinoita bleach azo dyes, vat dye oxidised forms, uye mavara ari mumapepa nemachira. Chimiro chayo chakasimba chinoita kuti zvive nyore kuchengeta nekubata mumabasa madiki.
Mabhenefiti Pamusoro peSodium Dithionite
TDO inogara kwenguva refu pasherufu kupfuura sodium dithionite kana yakachengetedzwa munzvimbo dziri kure, zvichiita kuti ive yakakodzera kushandiswa pabasa rine mwero wakaderera kana nzvimbo dziri kure dzisina kutumirwa kakawanda. Inoshanda patembiricha iri pamusoro pe50°C mualkaline solution (pH > 9), zvichipa mwero wekutonga kuti bleach inotanga riini - hupfu hunogona kuchengetwa zvakachengeteka uye kusanganiswa huchitonhora usati wadziiswa bleach kuti uishandise. Kushanda uku kunodzorwa nekupisa kunoderedzawo kuora kwechinhu panguva yekusanganisa formula.
Mashandisirwo uye Kugoverwa
Thiourea dioxide inoshandiswa mukudhinda machira (kudhinda patani nekuparadza ruvara rwedhayi yevhati), mukuchenesa huni sekuwedzera kana imwe nzira panzvimbo yesodium dithionite, uye senzira yekuderedza huwandu hwezvinhu mukugadzirwa kwemakemikari akakosha. Terracore Chemicals inopa thiourea dioxide yemhando yepamusoro mumabhegi e25 kg ekugadzira machira, mafekitori emapepa, uye vashandisi vemakemikari emaindasitiri muSouth Africa yese.
Applications
- Kudhinda kwepurasitiki yemucheka nedhayi dzevhati
- Kuchenesa kwedonje nemvere dzemakwai kunobvisa kuchena
- Kuvandudzwa kwekupenya kwepepa nekanika
- Kubvisa ruvara kubva pakugadzirisa dhayi yefaibha yakapendwa
- Kuderedzwa kwekusarudza mukugadzirwa kwemakemikari
- Imwe nzira yekuchengetedza kwenguva refu inotsiva sodium dithionite
