Okukhethwayo kushushu-diphu intsimbi strip
Inkqubo yeMveliso
Isigaba I
Yonke i-coil ye-strip steel iya kuxutywa kwaye ihlanjululwe ukufikelela kwindawo eqaqambileyo necocekileyo.
Isigaba II
1.I-Hot-dip galvanizing: emva kokukhetha, icocwa nge-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye i-ammonium chloride kunye ne-zinc chloride exutywe ngetanki yesisombululo esinamanzi.Emva koko ithunyelwa kwitanki yokugalela idiphu eshushu ukuze igalelwe.
2.Hot galvanizing: emva pickling, icocwe kwibhafu ye-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye i-ammonium chloride kunye ne-zinc chloride exutywe nesisombululo esinamanzi, kwaye emva koko ithunyelwe kwibhafu ye-galvanizing emva kokuqhubekeka komlilo we-annealing for galvanizing.
3.I-galvanizing ngqo: emva kokukhetha, ithunyelwa kwisithando somlilo esiqhubekayo kwaye emva koko kwitanki ye-galvanizing for galvanizing.
Isigaba III
Emva kokuba intsimbi ye-strip ifakwe i-galvanized, iya kuhlanganiswa kwaye ifakwe kwindawo yokugcina.Uluhlu lwe-galvanized alunakuba ngaphantsi kwe-50g / m2 ngokweemfuno zabathengi, kwaye nayiphi na isampuli ayiyi kuba ngaphantsi kwe-48g / m2.
Intsimbi evundisiweyo isetyenziselwa ukwenza imibhobho yentsimbi, njengemibhobho yegreenhouse, imibhobho yamanzi okusela, imibhobho yokufudumeza, nemibhobho yokuhambisa igesi;Isenokusetyenziswa kulwakhiwo, kushishino olulula, iimoto, ezolimo, ukufuya izilwanyana, ukuloba, urhwebo kunye namanye amashishini.
Umcu wentsimbi owenziwe ngesinyithi ubonisa ukuba ishishini lokwakha lisetyenziselwa ikakhulu ukwenza iipaneli ezichasene ne-corrosive kwimizi-mveliso kunye nezakhiwo zoluntu, iigridi zophahla, njl.Umzi-mveliso wokukhanya uyisebenzisela ukwenza amaqokobhe esixhobo sesixhobo sasekhaya, iitshimini zasekuhlaleni, izixhobo zasekhitshini, njl.Ezolimo, ukufuywa kwezilwanyana kunye nokuloba zisetyenziswa ikakhulu njengokugcinwa kokutya kunye nokuthutha, izixhobo zokulungisa umkhenkce wenyama kunye neemveliso zasemanzini, njl.Ukurhweba, isetyenziswa ikakhulu njengokugcina, ukuthutha kunye nezixhobo zokupakisha izinto;Isakhiwo sentsimbi ye-sandalwood bar (i-C, i-Z eyintsimbi);I-keel yentsimbi ekhanyayo, i-ceiling keel, njl.

Ukusetyenziswa koMtya weNsimbi oyiGalvanized
Intsimbi evundisiweyo isetyenziselwa ukwenza imibhobho yentsimbi, njengemibhobho yegreenhouse, imibhobho yamanzi okusela, imibhobho yokufudumeza, nemibhobho yokuhambisa igesi;Isenokusetyenziswa kulwakhiwo, kushishino olulula, iimoto, ezolimo, ukufuya izilwanyana, ukuloba, urhwebo kunye namanye amashishini.Ushishino lolwakhiwo lusetyenziswa ikakhulu ukwenza iipaneli zophahla oluchasene nomhlwa kwimizi-mveliso kunye nezakhiwo zoluntu, iigridi zephahla, njl.Umzi-mveliso wokukhanya uyisebenzisela ukwenza amaqokobhe esixhobo sesixhobo sasekhaya, iitshimini zasekuhlaleni, izixhobo zasekhitshini, njl.Ezolimo, ukufuywa kwezilwanyana kunye nokuloba zisetyenziswa ikakhulu njengokugcinwa kokutya kunye nokuthutha, izixhobo zokulungisa umkhenkce wenyama kunye neemveliso zasemanzini, njl.Ukurhweba, isetyenziswa ikakhulu njengokugcina, ukuthutha kunye nezixhobo zokupakisha izinto;Isakhiwo sentsimbi ye-sandalwood bar (i-C, i-Z eyintsimbi);I-keel yentsimbi ekhanyayo, i-ceiling keel, njl.
Iimpawu zomcu wentsimbi: umcu wentsimbi luhlobo lwemathiriyeli ekrwada ebizwa ngokuba yi (zinc) eqatywe kwipleyiti yentsimbi ende okanye emxinwa eqengqelekayo okanye eshushu.I-galvanizing eshushu ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende.Iimpendulo ezintsonkothileyo ngokwasemzimbeni kunye neekhemikhali phakathi kombhobho wentsimbi oshushu-dip wagalvanized kunye nesisombululo esinyibilikisiweyo se-plating senza umaleko we-zinc-iron alloy onganyangekiyo kunye nesakhiwo esibambeneyo.I-alloy layer idityaniswe ne-zin c ecocekileyo kunye ne-strip substrate yentsimbi.Ngoko ke, inokumelana ne-corrosion enamandla.Amanqaku omgangatho wentsimbi egudileyo aya kuba mpuluswa ngenkangeleko, angabi namaqhuqhuva e-zinc kunye ne-burrs, kunye nesilivere emhlophe;Ubukhulu buyalawuleka, phakathi kwe-5-107 μ Naluphi na ukhetho ngaphakathi kwe-m;Akukho nto i-hydrogen embrittlement kunye nobungozi bokushisa, obunokuqinisekisa ukuba iimpawu zomatshini zezinto zihlala zingatshintshi;Ingathatha indawo yezinye iinkqubo ezifuna ukugalelwa okushushu;Ukumelana ne-corrosion elungileyo, uvavanyo lokutshiza lwetyuwa olungathathi hlangothi ukuya kuthi ga kwiiyure ezingama-240;njl njl.Intsimbi yentsimbi inikezelwa ngokubanzi kwiikhoyili, enenzuzo yokuchaneka komgangatho ophezulu, umgangatho omhle womphezulu, ukusetyenzwa lula kunye nokugcinwa kwezinto eziphathekayo.
Indlela yokupakisha: i-bundle, i-wood case
Imo yokuthumela ngaphandle: uthutho lwemoto
