Iindaba

Ukuyisebenzisa ngokupheleleyo imveliso, umntu kufuneka aqale ayiqonde kakuhle, kwaye imiqulu egqunywe ngombala ayifani. Okulandelayo, makhe sizazise kwimiqulu eqatywe ngombala.
Okokuqala, kufuneka sazi ukuba yeyiphi ibhodi eqatywe ngombala?

Umtya wentsimbi ogqunywe ngombala usebenzisa intsimbi eshushu-diphu eyenziwe ngamazimba njengoko i-substrate ayinamaleko e-zinc yokukhusela, kodwa ikwanayo ne-organic coating kwi-zinc layer yokhuselo kunye nokukhusela, ukuthintela umcu wentsimbi ukuba ungagqwala. Ubomi bayo benkonzo bu malunga namaxesha angama-1.5 ubude kunomtya wensimbi. Okwesibini, kufuneka siqale siqonde iinjongo zemiqulu eqatywe ngemibala? Imiqulu eqatywe ngemibala ikhaphukhaphu, iyathandeka ngobuhle, kwaye inokumelana nokudleka okulungileyo. Zinokusetyenzwa ngokuthe ngqo kwaye zifumaneka ngokubanzi kwimithunzi yegrey emhlophe, ulwandle oluluhlaza, kunye nobomvu bezitena. Zisetyenziswa ikakhulu kwizibhengezo, ulwakhiwo, izixhobo zombane zasekhaya, ifanitshala noshishino lwezothutho.
Ukugquma okusetyenziselwa imiqulu egqunywe ngombala kufuneka kukhethe iireyini ezifanelekileyo ngokweendawo ezahlukeneyo zokusetyenziswa, ezifana nepoliester silicon modified polyester, polyvinyl chloride plastic sol, polyvinylidene chloride, njl. Okulandelayo, kufuneka ukwazi ukwakheka kokutyabeka:
Uhlobo lwesakhiwo sokugquma
I-2/1: Faka isicelo kabini kwindawo ephezulu, kube kanye kwindawo ephantsi, kwaye ubhake kabini.
I-2/1M: Faka isicelo kabini kwindawo ephezulu nangaphantsi, kwaye ubhake kube kanye.
I-2/2: Faka isicelo kabini kwindawo ephezulu nangaphantsi, kwaye ubhake kabini.
Ukusetyenziswa kwezakhiwo ezahlukeneyo zokugquma:
I-2/1: Ukumelana nokugqwala kunye nokumelana nokukrweleka kwepeyinti yomqolo omnye ayilunganga, kodwa inoncamathelo elungileyo kwaye isetyenziswa kakhulu kwiipaneli zesandwich;
I-2/1M: Ipeyinti yangasemva inokumelana nokugqwala okuhle, ukumelana nokukrweleka, kunye nokwakheka kokusetyenzwa, kunye nokunamatheliswa kakuhle, okufanelekileyo kwiipaneli ezineprofayili enye kunye neepaneli zesandwich.
I-2/2: Ipeyinti ephindwe kabini ngasemva inokumelana nokugqwala okuhle, ukuchasana nokukrweleka, kunye nokwakheka kokusetyenzwa, kwaye isetyenziswa kakhulu kwiiphaneli ezineprofayile ezinomaleko omnye. Nangona kunjalo, ukunamathela kwayo kumbi kwaye ayifanelekanga kwiipaneli zesandwich.

Luluphi ulwahlulo lwee-substrates ezigqunywe ngombala?
Idiphu eshushu i-galvanized substrate
Imveliso efunyenwe ngokusebenzisa organic ukutyabeka phezu eshushu-dip galvanized sheet sheet is hot-dip galvanized color sheeted sheet. Idiphu eshushu enombala ogqunywe ngephepha ayinayo impembelelo yokukhusela ye-zinc kuphela, kodwa i-organic coating kumphezulu ikwadlala indima ekukhuseleni ukugquma kunye nokuthintela umhlwa, kunye nobomi benkonzo obude kuneshiti elishushu lokudipha. Umxholo we-zinc we-hot-dip galvanized substrates ngokubanzi yi-180g/m2 (i-double-side), kwaye umxholo we-zinc ophezulu we-hot-dip galvanized substrates ukwenzela ukusetyenziswa kwangaphandle kwizakhiwo yi-275g/m2.
Idiphu eshushu i-aluminium zinc substrate
Idiphu eshushu i-aluminium zinc ipleyiti yentsimbi (55% Al Zn) isetyenziswa njenge substrate esanda kugqunywa, idla ngokuba nomxholo we-aluminium zinc we-150g/㎡ (amacala amabini). Ukumelana nephepha le-aluminiyam ye-aluminiyam eshushu-i-2-5 amaxesha ashushu-diphu ephepheni. Ukusetyenziswa ngokuqhubekayo okanye okwethutyana kumaqondo obushushu ukuya kwi-490 ℃ akusayi kubangela i-oxidation enzima okanye ukwakheka kwezikali ze-oxide. Ukukwazi ukubonakalisa ubushushu kunye nokukhanya kuphindwe kabini kune-hot-dip galvanized steel plate, kunye ne-reflection enkulu kune-0.75 yinto efanelekileyo yokwakha yokugcina amandla.
I-electroplated galvanized substrate
Imveliso efunyenwe ngokusebenzisa i-electroplated galvanized sheet njengoko i-substrate kunye nokubhaka nge-organic coating i-electroplated galvanized sheet coated sheet. Ngenxa yomaleko we-zinc obhityileyo we-electroplated galvanized sheet, umxholo we-zinc udla ngokuba yi-20/20g/m2, ngoko ke le mveliso ayifanelekanga ukusetyenziswa ngaphandle ekwenzeni iindonga, uphahla, njl. ingasetyenziselwa ubukhulu becala izixhobo zendlu, izixhobo zeaudio, ifenitshala yentsimbi, uhombiso lwangaphakathi, njl.njl. Emva kokuva oku, ngaba unalo ulwazi malunga nemiqulu eqatywe ngemibala? Ukuba unomdla, yiza uze uqhagamshelane nathi!
