Kutheni le nto umsonto ujikeleza ubhubhe emvaI-Sulfur Black Br umbala wedayi?Ndingayinqanda njani?Yintoni esifanele sinikele ingqalelo kuyo kwinkqubo?
Idayi emnyama ye-sulfide iyikhompawundi ephakamileyo ye-molecular equkethe i-sulfure eninzi, isakhiwo sayo siqulethe iibhondi ze-disulfide kunye neebhondi ze-polysulfide, kwaye azinzile kakhulu.Ngokukodwa, ibhondi ye-polysulfide inokuthi ifakwe kwi-oksijini yesulfure emoyeni phantsi kweemeko ezithile zokushisa kunye nokufuma, kwaye idibanise ngakumbi kunye neemolekyuli zamanzi emoyeni ukuvelisa i-asidi ye-sulfuric, ngaloo ndlela inciphisa amandla omsonto ojikelezayo, i-fiber brittleness, kwaye zonke iintsinga zi-embrittle zibe ngumgubo xa ziqatha.
Ngesi sizathu, ukuze kuncitshiswe okanye kuthintelwe umonakalo wefiber brittleness emva kokusonta umsonto ngeI-Sulfur Black Br idayi, la manqaku alandelayo kufuneka athathelwe ingqalelo:①Isixa seI-Sulfur Black Br Idayi kufuneka ilinganiselwe, kwaye inani ledayi yesilika ekhethekileyo akufanele idlule i-700g / iphakheji.Ngenxa yokuba ubuninzi bedayi buphezulu, ithuba lokukhwabanisa likhulu, kwaye ukukhawuleza kokudaya kuyancipha, kwaye ukuhlamba kunzima ngakumbi.②Emva kokuba umbala kufuneka uhlanjwe ngokupheleleyo, musa ukuhlamba ucocekile, umbala ojikelezayo kumgca wokusonta kulula ukubola kwi-asidi ye-sulfuric kwinkqubo yokugcina kwaye wenze i-fiber brittle.③Emva kokufakwa kombala, i-urea, i-soda ash kunye ne-acetate ye-sodium kufuneka isetyenziswe kunyango oluchasene ne-brittleness.④Umsonto osontayo ubiliswa emanzini acocekileyo phambi kokuba ufakwe umbala, kwaye iqondo le-embrittlement lomsonto osontayo emva kovavanyo lingcono kunelo lelaphu elibilisiwe.⑤Umsonto osontayo kufuneka womiswe kwangethuba emva kokufakwa kombala, kuba umsonto omanzi ufudunyezwa nje ngexesha lenkqubo yokupakisha, okunciphisa umxholo we-anti-brittleness agent kunye nexabiso le-pH lomsonto ojikelezayo, ongathandekiyo kwi-anti-brittleness.
Emva kokoma, umsonto osontayo kufuneka upholiswe ngokwemvelo, ukuze ubushushu bomsonto wokusonta bupakishwe phambi kokuba buwele kwiqondo lobushushu begumbi.Ngenxa yokuba ayipholiswanga emva kokumisa kwaye ipakishwe ngokukhawuleza, ukushisa akulula ukusabalalisa, okwandisa amandla okubola kwedayi kunye ne-asidi, okubangela ukuba kunokwenzeka ukuba i-fiber ibe brittle.
Ukukhethwa kwe-anti-brittle-I-Sulfur Black Br idayi, iidayi ezinjalo zongezwe kwi-formaldehyde kunye ne-chloroacetic acid xa kuveliswa, isiphumo se-methyl-chlorine vulcanized anti-brittle-black, ukuze ii-athom zesulfure ezixutywe lula zibe yimeko ezinzileyo, enokuthintela i-oxidation ye-athomu yesulfure ukuvelisa. acid kunye nefiber brittle.
