Amagama angundoqo enqaku: iThiourea, Izicelo zaseThiourea, Abavelisi baseThiourea
I-Thiourea isetyenziswa kwiindawo ezininzi, ukuguquguquka kwayo okubangelwa ziimpawu zayo ezikhethekileyo zeekhemikhali kunye nemisebenzi eyahlukeneyo.
Okokuqala nokubalulekileyo, i-thiourea idlala indima ebalulekileyo kummandla wokwenziwa kwezinto eziphilayo.
Isebenza njengesixhobo esibalulekileyo, esisetyenziswa ekuhlanganiseni uluhlu olubanzi lweekhompawundi ze-organic—kuquka amayeza, iidayi, kunye nezibulali-zinambuzane.
IThioureaikwadlala indima ebalulekileyo kwishishini lerabha. Isebenza njengesikhawulezisi se-vulcanization yerabha, iphucula isantya kunye nobubanzi benkqubo ye-vulcanization, ngaloo ndlela iphucula iipropati zomzimba kunye nezokucubungula izinto. Ukufakwa kwe-thiourea kwenza iimveliso zerabha ziqine ngakumbi kwaye zinwebeke, zihlangabezana ngempumelelo neemfuno zezicelo ezahlukeneyo zoshishino.
Ngaphezu koko, i-thiourea yinto ebalulekileyo ekufakeni igolide. Kwishishini lokufaka i-electroplating, isebenza njengesithako kwiibhafu zokufaka igolide, iphucula ukufana kunye nokukhazimla kwengubo efakwe igolide kwaye iphumela kwiimveliso ezifakwe igolide ezithandekayo kwaye zihlala ixesha elide. Kwangaxeshanye, i-thiourea ingasetyenziswa kwiinkqubo zokufaka i-electroplating zezinye izinyithi—ezifana nesilivere kunye nobhedu—ezibonelela ngenkxaso ebalulekileyo yezinto ezikrwada kwicandelo lokufaka i-electroplating. Ngaphandle kwezicelo ezikhankanyiweyo apha ngasentla, i-thiourea ikwasetyenziswa kwikhemistri yohlalutyo, apho isebenza njenge-reagent okanye isalathisi kwiimpendulo ezithile zeekhemikhali.
Iimpawu zayo ezikhethekileyo zeekhemikhali zinika i-thiourea amandla athembisayo okusetyenziswa kwicandelo lohlalutyo lweekhemikhali. Nangona kunjalo, kufuneka kuthathwe amanyathelo athile okhuseleko xa kusetyenzwa i-thiourea.
Umzekelo, i-thiourea kufuneka igcinwe kwindawo epholileyo neyomileyo kwaye igcinwe kude nezinto ezifana nee-oxidizing agents kunye nee-asidi ukuthintela iimpembelelo zeekhemikhali ezinokukhokelela ekuwohlokeni okanye kwiimeko eziyingozi.
Ukongeza, xa usebenzisa i-thiourea kwiimpendulo zamakhemikhali, ulawulo oluqinileyo kwiiparameter zempendulo—ezifana nobushushu kunye namanqanaba e-pH—lubalulekile ukuqinisekisa ukuqhubela phambili okuthe tye kwempendulo kunye nobunyulu bemveliso ephumayo.
Njengomthengisi we-thiourea, i-Aojin Chemical inikezelai-thioureayomgangatho ophezulu kwaye ikwiinkcukacha ezahlukeneyo zokusetyenziswa njenge-accelerator ye-vulcanization. Ipakishwe kwiingxowa ezingama-25kg, imveliso yethu yenzelwe ukuhlangabezana neemfuno ezahlukeneyo zezicelo ezahlukeneyo. Siyakumema ukuba unxibelelane nathi ukuze ufumane ulwazi oluthe kratya.
