I. Production line control.
① Rininitrile girovhosi muchina uri kutengeswa's iyo boiler yemafuta tembiricha inosvika 190 ℃, iyo yekumhanyisa yekugadzira ≤m ≤65pcs/min.
②Kana iyo boiler yemafuta tembiricha yakadzikira kupfuura 145 ℃, kumhanya kunofanirwa kuderedzwa zvinoenderana nechiyero chekuomeswa kwefirimu rerabha.
③ kana iyo boiler yemafuta tembiricha yakadzikira kupfuura 130 ℃ inofanira kutorwa nekukasira kumisa kugadzirisa.
Chechipiri, kuisa nitric acid solution: nitric acid concentration inofanira kudzorwa pa 3% -4%, kuwedzera nitric acid solution kune nitric acid tangi inofanira kugadzirwa pachine nguva nekusangana kwakafanana kwemhinduro, mushandisi anorambidzwa zvachose kuwedzera mvura kana. nitric acid kune tangi pakuda.
Chechitatu, kuisa alkaline mvura: 5-10Kg yealkali inowedzerwa kune alkali tangi mune imwe neimwe shanduko panguva yekugadzirwa kwakajairika, uye 1 nguva mushure memaawa mana mukuchinja kunotevera.
Zvina, kukwesha kwemaoko: ① bhurashi tangi tembiricha inofanira kudzorwa pa45 ± 15 ℃.
②Mvura yekugeza mold inofanirwa kugara yakafashukira uye inogara ichigadziridzwa nehuhu hwemvura, uye mhando yemvura inofanirwa kunyatsogadziridzwa kamwe chete maawa masere.
③Mold yekugezesa mabhurashi anofanirwa kugara achitariswa kuti bvudzi rakapfekwa here kuti ive nechokwadi chekubhurasha.
④Mold washing brushes zvinorambidzwa zvachose kusvibiswa nemafuta zvinhu.
Katatu dipping mvura inopisa.
① tembiricha yetangi yemvura inopisa inofanirwa kudzorwa mukati meiyo 80 ± 15 ℃, iyo mhando yemvura inogara ichigadziridzwa kuchengetedza mafashama.Imwe neimwe asidhi maoko ekugeza mold kuti ichinje kamwechete.
Chechina, kuitisa starch coagulant.
① starch coagulant CaCL2 zvemukati kutonga pa8±3%.
②Starch coagulant tembiricha inodiwa 65±15℃.
③ Starch coagulant inofanira kunyatso mutswa kamwe chete 50-60 maminetsi.
③ starch coagulant mazuva ese mana-8 kunyatsogadzirisa kamwechete.
V. Starch coagulant drying: ① mold yemaoko kubva muchoto inofanira kugara yakaoma asi kunyorova kwemaoko zvishoma.
