I. Taolo ea line ea tlhahiso.
① Nengmochini oa li-glove oa nitrile oa rekisoa's mocheso oa oli ea boiler o fihla ho 190 ℃, lebelo la tlhahiso ≤m ≤65pcs/min.
②Ha mocheso oa oli oa boiler o le tlase ho 145 ℃, lebelo le lokela ho fokotsoa ho latela tekanyo ea ho omisa filimi ea rabara.
③ ha mocheso oa oli oa boiler o le tlase ho 130 ℃ o lokela ho nkoa hang-hang ho emisa ho sebetsa.
Ea bobeli, ho kenya tharollo ea nitric acid: mahloriso a nitric acid a lokela ho laoloa ho 3% -4%, ho eketsa tharollo ea nitric acid ho tanka ea nitric acid e tlameha ho lokisoa esale pele ka mahloriso a tšoanang a tharollo, mosebeletsi o thibetsoe ka tieo ho eketsa metsi kapa asiti ea nitric ho tanka ka thato.
Ea boraro, ho kenya metsi a alkaline: 5-10Kg ea alkali e eketsoa ka tanka ea alkali ka nako e 'ngoe le e' ngoe nakong ea tlhahiso e tloaelehileng, le nako e le 'ngoe ka mor'a lihora tse 4 phetohong e latelang.
Tse 'nè, ho hlatsoa hlobo ka letsoho: ① mocheso oa tanka ea brush e lokela ho laoloa ho 45 ± 15 ℃
②Metsi a hlatsoang hlobo a lokela ho bolokoa a khaphatseha le ho nchafatsoa khafetsa ka boleng ba metsi, 'me boleng ba metsi bo lokela ho ntlafatsoa hang ka mor'a lihora tse ling le tse ling tse 8.
③Marashe a ho hlatsoa hlobo a lokela ho hlahlojoa khafetsa hore na moriri o roaloa joang ho etsa bonnete ba hore o na le borashe.
④Marashe a ho hlatsoa hlobo a hanetsoe ka botlalo ho silafatsoa ka lintho tsa oli.
Tse tharo tse qoelang metsi a chesang.
① mocheso oa tanka ea metsi a chesang o lokela ho laoloa ka har'a 80 ± 15 ℃, boleng ba metsi bo lula bo nchafatsoa ho boloka boemo ba ho phalla.E 'ngoe le e' ngoe ea acid e hlatsoa hlobo e tla nkeloa sebaka 1 nako.
Tse 'nè, ho kenya starch coagulant.
① Taolo ea litaba tsa starch coagulant CaCL2 ho 8±3%.
② Tlhoko ea mocheso oa starch coagulant 65 ± 15 ℃.
③ Starch coagulant e lokela ho tsosoa hantle hang ka mor'a metsotso e meng le e meng e 50-60.
③ starch coagulant matsatsi a mang le a mang a 4-8 ho ntlafatsa nako e le 'ngoe.
V. Starch coagulant drying: ① hlobo ea letsoho e tsoang ka ontong e lokela ho bolokoa e omme empa hlobo e tlameha ho bolokoa e le metsi hanyane.
