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 loxhathiso oludityanisiweyo olubandayo olwenziwe 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; Intsimbi ekugobeni okuqinileyo iya kuba mncinci ngenxa yokwelula.
Isiphako sokugoba okungenanto kukuba xa icala elingaphezulu / icala ligoba ngaxeshanye lingenanto, ngenxa yokuba umqulu ophezulu kunye nomqulu osezantsi uvelisa uxinzelelo kunye, ityhubhu yesikwere esinezikwere esitokhweni, 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.
