I. Ulawulo lomgca weMveliso.
① Niniumatshini weglavu ye-nitrile uyathengiswa's ubushushu kwibhoyila ioli ifikelela 190℃, isantya imveliso ≤m ≤65pcs/min.
②Xa i-oyile ye-boiler iqondo lokushisa lingaphantsi kwe-145 ℃, isantya kufuneka sincitshiswe ngokuhambelana neqondo lokumisa ifilimu yerabha.
③ xa i-oyile yebhoyila iqondo lobushushu lingaphantsi kwe-130 ℃ kufuneka lithathwe ngoko nangoko ukumisa ukusetyenzwa.
Okwesibini, ukumitha isisombululo se-nitric acid: ugxininiso lwe-nitric acid kufuneka ilawulwe kwi-3% -4%, ukongeza isisombululo se-nitric acid kwitanki ye-nitric acid kufuneka iqwalaselwe kwangaphambili kunye noxinzelelo olufanayo lwesisombululo, umqhubi unqatshelwe ngokungqongqo ukongeza amanzi okanye acid nitric kwitanki ngentando.
Okwesithathu, ukukhulelwa kwamanzi e-alkaline: i-5-10Kg ye-alkali yongezwa kwitanki ye-alkali kwi-shift nganye ngexesha lemveliso eqhelekileyo, kunye nexesha eli-1 emva kweeyure ezi-4 kwinguqu elandelayo.
Isine, ukubrasha ngundo ngesandla: ① ibrashi itanki lobushushu kufuneka ilawulwe 45 ± 15 ℃
②Amanzi okuhlamba umngundo kufuneka agcinwe ephuphuma kwaye ahlaziywe rhoqo ngomgangatho wamanzi, kwaye umgangatho wamanzi kufuneka uhlaziywe ngokucokisekileyo kanye kwiiyure ezisi-8.
③Iibhrashi zokuvasa umngundo kufuneka zijongwe rhoqo xa iinwele zinxitywa ukuqinisekisa isiphumo sokubrasha.
④Iibhrashi zokuhlamba umngundo azivumelekanga kwaphela ukuba zingcoliswe zizinto zeoyile.
Ukudipha amanzi ashushu amathathu.
① ubushushu betanki yamanzi ashushu kufuneka ilawulwe ngaphakathi koluhlu lwe-80 ± 15 ℃, umgangatho wamanzi uhlaziywa rhoqo ukugcina imeko yokuphuphuma.I-asidi nganye yokuhlamba izandla i-mold ukuze itshintshwe ixesha eli-1.
Isine, ukumitha isitashi coagulant.
① isitashi coagulant CaCL2 ulawulo lomxholo kwi-8±3%.
②Imfuno yesitashi coagulant ubushushu 65±15℃.
③ I-starch coagulant kufuneka ishukunyiswe ngokucokisekileyo kanye ngemizuzu engama-50-60.
③ isitashi coagulant rhoqo ngeentsuku ezi-4-8 ukuhlaziya ngokucokisekileyo ixesha eli-1.
V. Istatshi esomileyo esomileyo: ① ukungunda kwesandla ngaphandle kwe-oveni kufuneka kugcinwe komile kodwa ukungunda ngesandla kumanzi kancinci.
