Kutheni le nto umsonto ujikeleza ubhubhe emvaI-Sulfur Black Brumbala 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 Bridayi, la manqaku alandelayo kufuneka athathelwe ingqalelo:
① Ubungakanani bedayi yeSulfur Black Br kufuneka buncitshiswe, kwaye ubungakanani bedayi yombala okhethekileyo wesilika akufunekanga budlule kwi-700g/package. Ngenxa yokuba ubuninzi bedayi buphezulu, ithuba lokukhwabanisa likhulu, kwaye ukukhawuleza kokudaya kuyancipha, kwaye ukuhlamba kunzima ngakumbi.
② Emva kokuba umbala kufuneka uhlanjwe ngokupheleleyo, musa ukuhlamba ucoceko, umbala ojikelezayo kumgca wentambo ojikelezayo kulula ukubola kwi-asidi ye-sulfuric kwinkqubo yokugcina kwaye wenze i-fiber brittle.
③ Emva kokufakwa kombala, i-urea, i-soda ash kunye ne-acetate yesodium kufuneka isetyenziswe kunyango oluchasayo.
④ Umsonto osontayo ubiliswa emanzini acocekileyo phambi kokuba ufakwe umbala, kwaye iqondo le-embrittlement lomsonto osontayo emva kovavanyo lingcono kunelo lelaphu elibilisiwe.
⑤ Umsonto osontayo kufuneka womiswe ngexesha 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-Sulfur Black BrIdayi, iidayi ezinjalo zongezwe kwi-formaldehyde kunye ne-chloroacetic acid xa kuveliswa, isiphumo se-methyl-chlorine vulcanized anti-brittle-black, ukuze iiathom zesulfure ezixutywe lula zibe yimeko ezinzileyo, enokuthintela i-oxidation ye-athomu yesulfure ukuvelisa. acid kunye nefiber brittle.
