Sodium Thiocyanate: Musamu Uubelesyegwa Mumafakitali
Zibeela Zipati Zyakubelesya
1. Kupanga ntambo zya acrylic
Sodium thiocyanate nchintu chiyandikana loko mukupanga ntambo zya acrylic. Muchiindi chakupangwa kwa acrylonitrile, sodium thiocyanate ibelekela mbuli chintu chiyumu, kupa busena butazungaani bwakusanduka kwa acrylonitrile. Ilanyonyoona ma acrylonitrile monomers kuti ipange nzila ya polymerization iikozyenye, eezi zipa kuti kube ma acrylic fibers mabotu. Insinga zya acrylic zilizyibidwe nkaambo kakukazya misamu, kutabola, akukwabilila kupya, zipa kuti zibelesyegwe kapati muzisani, muzisani zyaaŋanda, amuzisani zyamafakitali.
2. Chibelesyo chakulanga-langa misamu
Sodium thiocyanate nchintu chipati mukulanga-langa misamu. Ilakonzya kupanga zintu zikatazya antoomwe ama ayoni aabutale mbuli ma ayoni aabutale, ikuzumizya kujana akuvwuntauzya mweelwe wama ayoni aaya kwiinda mukubelesya nzila zya colorimetric naa titration. Mbuli chitondeezyo, mukulanga-langa ma ayoni aabutale mumasampuli aamaanzi, sodium thiocyanate ilaswaangana ama ayoni aabutale kuchita chintu chisalala mbuli bulowa. Nzila zyakupima mibala zilakonzya kufwambaana akuziba kabotu bunji bwa iron ions. Eeyi nzila ilaampindu kapati alimwi nnguba kubelesya, aboobo ilabelesyegwa kapati mukulanga-langa bubotu bwamaanzi, kulanga-langa busena, alimwi akulanga-langa bubotu bwamaanzi mumafakitali.
3. Makwebo aakupanga magesi
Mumulimo wakupanga magesi, sodium thiocyanate ilabelesyegwa loko mbuli chintu chiyungizyidwe mukupanga magesi. Zisumpula kubeleka kwachibaka chakubelesya magesi, chisumpula kweendelana akukakatila kwachintu, mpawo chiyungizya kukazyigwa akubola akuboneka kabotu kwazintu zibelesya magesi. Mbuli chitondeezyo, mukupanga magesi aamukuba, kuyungizya mweelwe weelede wa sodium thiocyanate kulesya kubola kwama ayoni aamukuba, eezi zipa kuti kube kuteteeta akukozyanisya kwamukuba kakwiina tumpenda tusyoonto. Kuyungizya waawo, sodium thiocyanate ilakonzya kubelesegwa mukubamba zintu ziyandisi zilimbuli ngolide ansiliva, ikusumpula kumweka akukazya kubola.
4. Kupanga zintu zipona
Sodium thiocyanate ilabelesyegwa kapati mukupanga zintu zipona. ilakonzya kubeleka mbuli chintu chakupanga zintu zipona. Mbuli chitondeezyo, mukupanga nitriles, sodium thiocyanate ilakonzya kuswaangana ama aldehydes naa ketones kuti ipange nitriles zyeendelana. Kwiindawo, sodium thiocyanate ilakonzya kubelesegwa kupanga misamu ya thiourea, eeyo iiyandika kapati mumilimo yamisamu, misamu iijaya tuzunda, amadayi. Ikukonzya kuchita zintu antoomwe akusala kwa sodium thiocyanate kupa kuti ube chintu chibelesegwa loko mukupanga zintu zipona.
5. Zimwi Zibelesyo
Sodium thiocyanate ilakonzya kubelesegwa kulizimwi zintu. Mbuli chitondeezyo, mumulimo wakudaya akusimba, ilakonzya kubelesegwa mbuli chigwasyo chakudaya kuchitila kuti madayi atanjili kabotu. Mumulimo wakupanga mapepa, ilakonzya kubelesegwa mukusanzya akugwisya inki kuchitila kuti mapepa abe kabotu akubeleka kabotu.

Kupaka akubamba
Sodium thiocyanate ilabikkwa muziyobwedo zijalilidwe kuchitila kuti izumanane kuyuma akubula tombe muchiindi chakweenzyegwa akuyobolwa. Kweelede kuyobolwa mubusena butontola, butuma, alimwi bujisi muya mubotu, kule azintu zikonzya kubola mbuli asidi ama alkali. Muchiindi chakubamba, kubikkila maanu kweelede kuchitwa kukulesya busi akutantamuka kupya kupati kuchitila kuti chintu chikkale kabotu akukwabililwa.
