I-degreasing surface ye-galvanized square tubes yindlela yokucoca esekelwe kwimpembelelo yekhemikhali ye-alkali.Ngenxa yokusetyenziswa kwayo okulula, ixabiso eliphantsi kunye nokufumaneka lula kwezinto, isetyenziswa ngokubanzi.Ngenxa yokuba inkqubo yokuhlamba i-alkali ixhomekeke kwi-saponification, i-emulsification kunye nezinye iziphumo, ukusebenza okungentla akukwazi ukufezekiswa nge-alkali enye.
Ngokuqhelekileyo, iindidi zamacandelo asetyenziswayo, kwaye ngamanye amaxesha i-surfactants kunye nezinye ii-agent ezincedisayo kufuneka zongezwe.I-alkalinity imisela iqondo lokusabela kwe-saponification, kwaye i-alkalinity ephezulu inciphisa ukuxinana komphezulu phakathi kwebala le-oyile kunye nesisombululo, okwenza i-oyile ibe lula ukumilisela.Ukongezelela, i-arhente yokucoca i-residual kwi-surface ye-galvanized square tube inokususwa ngokuhlamba kwamanzi emva kokuhlamba i-alkali.
Yindlela esetyenziswa ngokubanzi yokususa i-oyile ukusebenzisa i-surfactant enoxinzelelo oluphantsi lomphezulu, ukungeneka okulungileyo kunye nokumanzisa, kunye nekhono eliqinileyo lokumilisela.Ngokusebenzisa isiphumo se-emulsification ye-surfactant, imaski yobuso bobuso obunamandla athile yenziwa kujongano lwamanzi e-oyile, olutshintsha ujongano lwelizwe kunye nexabiso le-Wuxi galvanized square tube, ukuze amasuntswana e-oyile asasazwe kwisisombululo samanzi ukuze enze. i-emulsion.Okanye i-oyile ibala elinganyibilikiyo emanzini kwityhubhu yesikwere esine-galvanized inokunyibilika kwi-surfactant micelle ngesiphumo sokunyibilika kwe-surfactant, ukuze kudluliselwe ibala leoli kwisisombululo samanzi.
Ityhubhu yesikwere evuthelweyo luhlobo lwetyhubhu yentsimbi enodonga olucekethekileyo enecandelo lesikwere esinomgongxo, ekwabizwa ngokuba yintsimbi epholileyo.Luhlobo lwentsimbi yecandelo kunye nobukhulu becandelo lesikwere, elenziwe ngentsimbi ye-Q235 eshushu-eshushu okanye epholileyo okanye ipleyiti edibeneyo njengesiseko sezinto ezisisiseko emva kokugoba okubandayo kunye nokwenza kunye ne-high-frequency welding.Ukongeza ukutyeba eludongeni, idimension yembombo kunye nongqameko oluthe tye lwetyhubhu eshinyeneyo eyongeziweyo eludongeni lufikelela okanye lugqithise kwinqanaba lokumelana ne-welded ebandayo eyenze ityhubhu yesikwere.
Iingenelo zokugoba kokwenyani kukubuyela umva okuncinci, ukubunjwa okuchanekileyo, kunye nemilo echanekileyo yokuqengqeleka kuphela.I-R yokwenziwa kwe-engile yangaphakathi ichaneke ngakumbi.Inzuzo yokugoba okungenanto kukuba ubude becala bunokugoba xa ukugoba kwangempela kungenakwenziwa, njengokugoba okuhambelanayo kunye nokugqiba imiphetho ephezulu / yecala leetyhubhu zesikwere eziphekiweyo.Ukugoba umngxuma kunokugoba i-angle yangaphakathi kunye ne-R<0.2t ngaphandle kokuphula udonga lombhobho.
Isiphene sokugoba kokwenyani kukuqina/kubhitya.
Ukugoba kwangempela kuya kwenza indawo yokugoba ilula, kwaye umphumo wokwelula uya kunciphisa ubude bexesha elide lomgca wokugoba;Isinyithi kwi-bend eqinile iya kuba yincinci ngenxa yokwelula.
Isiphako sokugoba okungenanto kukuba xa icala eliphezulu / icala ligoba ngaxeshanye lingenanto, ngenxa yokuba umqulu ophezulu kunye nomqulu osezantsi uvelisa uxinzelelo kunye, ityhubhu yesikwere esiphekiweyo sisesitokhweni, kwaye amandla okwenza kube lula ukudlula inqaku elibalulekileyo. , ukwenza imiphetho ye-concave engazinzanga, ububanzi obukhulu be-galvanized square tube, kwaye iya kuchaphazela nokusebenza okuzinzile kweyunithi kunye nomgangatho wokwenza.Oku kukwaluphawu olwahlukileyo lokugotywa komngxuma weetyhubhu zesikwere ezenziwe ngamazi.
