Amaphepha e-galvanizedzingahlulwa zibe ziindidi ezilandelayo ngokweendlela zemveliso kunye nokucubungula:
(1)Ishidi lesinyithi elitshisiweyo elishushuIshiti yentsimbi ebhityileyo ifakwa kwibhafu ye-zinc enyibilikisiweyo ukuze kwenziwe ishiti yentsimbi ebhityileyo enomaleko we-zinc onamathela kumphezulu wayo. Okwangoku, ukusetyenziswa okuphambili kwenkqubo yokuvelisa i-galvanizing eqhubekayo, oko kukuthi, imiqulu yentsimbi ifakwa rhoqo kwibhafu ye-zinc enyibilikisiweyo eyenziwe ngentsimbi egqunyiweyo;
(2) intsimbi exutyiweyo. Le pleyiti yentsimbi nayo yenziwa ngokuntywila okushushu, kodwa emva nje kokuphuma etankini, ifudunyezwa ukuya kuthi ga kwi-500 ℃, ukuze ivelise ifilimu encinci ye-zinc kunye ne-iron alloy. Olu hlobo lwephepha lentsimbi exutyiweyo lunamathele kakuhle kwipeyinti kwaye luyakwazi ukuwelda;
(3) Iphepha lentsimbi elifakwe i-electro-galvanized. Ukwenziwa kweli phepha lentsimbi elifakwe i-galvanized ngendlela ye-electroplating kulula ukuyisebenzisa. Nangona kunjalo, i-coating incinci kwaye ukumelana nokugqwala akulunganga njengokwephepha le-galvanized elifakwe i-hot-dip;
(4) Ishiti yentsimbi egalelwe kakubi emacaleni omabini neyamacala amabini. Ishiti yentsimbi egalelwe emacaleni omabini, oko kukuthi, egalelwe emacaleni omabini kuphela emveliso. Iyakwazi ukuguquguquka ngcono kuneshiti yentsimbi egalelwe emacaleni amabini ngokubhekiselele ekudibaniseni, ekupeyinteni, ekulweni nokugqwala kunye nokucubungula. Ukuze koyiswe iziphene ze-zinc engagalelwanga emacaleni omabini, kukho olunye uhlobo lweshiti yentsimbi egalelwe ngomaleko omncinci we-zinc kwelinye icala, oko kukuthi, ishiti yentsimbi egalelwe emacaleni amabini;
(5) I-alloy kunye ne-composite galvanized steel sheet. Yenziwe nge-zinc kunye nezinye iintsimbi ezifana ne-aluminium, i-lead, i-zinc kunye nezinye ii-alloys kunye nentsimbi edityanisiweyo. Olu hlobo lwepleyiti yentsimbi lunentsebenzo entle kakhulu yokumelana nomhlwa kunye nokusebenza kakuhle kokupenda;
Ukongeza kwezi zintlanu zingasentla, kukwakho nentsimbi enemibala egalelweyo, intsimbi eprintiweyo nepeyintiweyo, intsimbi egalelweyo egalelweyo ePVC, njl. Nangona kunjalo, eyona isetyenziswa kakhulu okwangoku iseseyiyoIpleyiti yesinyithi eshushu.
Inkangeleko yentsimbi egalelweyo
[1] Imeko yomphezulu:Ipleyiti egalelweyoNgenxa yenkqubo yokugquma ekuphathweni ngeendlela ezahlukeneyo, imeko yomphezulu yahlukile, njengentyatyambo ye-zinc eqhelekileyo, intyatyambo ye-zinc entle, intyatyambo ye-zinc esicaba, intyatyambo engenazo i-zinc, kunye nonyango lwe-phosphate yomphezulu njalo njalo. Umgangatho waseJamani ukwachaza umgangatho womphezulu.
[2] Iphepha le-galvanized kufuneka libe nembonakalo entle, akufuneki kubekho ziphene ezinobungozi ekusetyenzisweni kwemveliso, ezinje ngokungabikho kweplating, imingxunya, ukuqhekeka, kunye ne-slag, ngaphezu kobukhulu beplating, ukukrala, amabala e-chromic acid, umhlwa omhlophe, njalo njalo.
Iipropati zoomatshini

① Ngokubanzi, kufuneka kuphela amaphepha e-galvanized akhiweyo, athambileyo kunye namacwecwe anzulu ukuze abe neempawu zokutsalwa. Iphepha le-galvanized elikhiweyo lifuneka ukuba libe nendawo yokukhupha, amandla okutsalwa kunye nobude, njl.njl.; ukutsalwa kufuna kuphela ukutsalwa. Amaxabiso athile ajonge "8" kweli candelo lemigangatho yemveliso efanelekileyo;
2. Indlela yovavanyo: iyafana nendlela yovavanyo lwentsimbi ebhityileyo ngokubanzi, jonga "8" ebonelelwe yimigangatho efanelekileyo kunye "nephepha lentsimbi yekhabhoni eliqhelekileyo" elidweliswe kumgangatho wendlela yovavanyo.
[2] Uvavanyo lokugoba:
Uvavanyo lokugoba yiprojekthi ephambili yokulinganisa ukusebenza kwenkqubo yesinyithi, kodwa imigangatho yesizwe yeemfuno ezahlukeneyo zesinyithi se-galvanized ayihambelani, umgangatho wase-US, ukongeza kwinqanaba lolwakhiwo, okuseleyo akudingi vavanyo lokugoba kunye nokuxinana. IJapan, ukongeza kwinqanaba lolwakhiwo, ishidi le-corrugated kunye neshidi le-corrugated ngokubanzi ngaphandle kokunye kufuneka yenze uvavanyo lokugoba.
Ukumelana nokugqwala kweshiti egayiweyo kuneempawu ezimbini eziphambili:
1, indima yokwaleka okukhuselekileyo
Kumphezulu ogqunyiweyo ukuze kwenziwe ifilimu ye-oxide exineneyo
2, xa ngesizathu esithile imikrwelo kwi-zinc coating, i-zinc ejikelezileyo isetyenziswa njenge-cation ukuthintela ukugqwala kwesinyithi.
