Kev ceev faj rau kev thauj mus los: ua ntej kev thauj mus los, xyuas seb lub thawv ntim khoom puas tiav thiab kaw, thiab xyuas kom meej tias lub thawv tsis xau, tawg, poob lossis puas thaum thauj.Nws yog nruj me ntsis txwv tsis pub sib tov nrog acids, oxidants, zaub mov thiab khoom noj khoom haus additives.Thaum lub sij hawm kev thauj mus los, cov tsheb thauj mus los yuav tsum tau nruab nrog cov khoom sib xws thiab cov khoom siv hluav taws kub thiab cov khoom siv kho mob thaum muaj xwm ceev.Thiab yuav tsum muaj kev tiv thaiv los ntawm tshav ntuj, nag thiab kub thiab tsim nyog yuav tsum tau tsav tsheb raws li txoj kev tau teev tseg, thiab tsis txhob nyob hauv thaj chaw nyob thiab thaj chaw muaj neeg coob coob;
Kev ceev faj cia
Muab kaw cia rau hauv qhov chaw txias thiab cua txias cais ntawm oxidant thiab alkali thiab tsis txhob sib xyaw cia.Khaws kom deb ntawm qhov hluav taws kub thiab qhov hluav taws kub thiab qhov hluav taws xob ncaj qha.it yuav tsum tau muab cov khoom siv hluav taws kub uas sib xws thiab ntau npaum li cas.Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau;
Ntim Ceev faj
Ordinary ntoo rooj sab nraum lub raj mis ampoule;Cov ntaub ntawv ntoo zoo tib yam sab nraud threaded iav lub raj mis, hlau cap pressed iav raj mis, lub raj mis yas los yog hlau chim (tau);tag nrho hauv qab lattice lub thawv, fiberboard lub thawv los yog lub thawv plywood sab nraum threaded iav raj mis, lub raj mis yas los yog tinplate chim (tau).
