Zvinozivikanwa kuti mhando yemachubhu akaenzana uye akaenzana akavharidzirwauye nzira yekuisa inokanganisa zvakananga kugadzikana kwezvivakwa zvesimbi.
Parizvino, zvinhu zvekutsigira zviri pamusika zvinonyanya kuve simbi yekabhoni. Zvinhu zvesimbi yekabhoni zvinowanzova Q235 neQ345, izvo zvinogadziriswa nekupisa galvanizing. Rutsigiro rwacho rwakagadzirwa nesimbi yestrip coil kuburikidza nekukotama kunotonhora, kusveta, kupisa galvanizing nezvimwe. Kazhinji, ukobvu hwacho hunofanira kunge hwakakura kupfuura 2mm, uye kunyanya kune dzimwe nzvimbo dzegungwa, dzakakwirira nedzimwe dzine mhepo, zvinokurudzirwa kuti ukobvu hwacho husave pasi pe2.5mm, zvikasadaro pane njodzi yekubvaruka panzvimbo yekubatanidza simbi.
Muzvivakwa zvikuru, zvepombi dzesimbi yekabhoni dzakagadzirwa nesimbi yakapetwa sikweya uye rectangular, ukobvu hwakadii hwezinc coating hunofanira kusvikwa kuti husvike pazvinodiwa zvehupenyu hwekushanda kwengura yezvakatipoteredza?
Sezvatinoziva tese, ukobvu hwekupisa-kunyika galvanizing imhando yakakosha yehunhu uye hunyanzvi hwehunyanzvipombi yesimbi yakarukwa, izvo zvine chekuita nekuchengetedzeka uye kugara kwenguva refu kwechivako. Kunyangwe paine mitemo yenyika neyehunyanzvi, ukobvu hwezinc coating husina kukodzera hwekutsigira kuchiri dambudziko rehunyanzvi rakapararira rekutsigira.
Maitiro ekugadzirisa simbi inopisa (hot-dip galvanizing) inzira yakasimba uye yakavimbika yekurapa pamusoro pesimbi kuti isapararire ngura munzvimbo dzakatikomberedza. Pane zvinhu zvakawanda zvinokanganisa simbi inopisa (hot-dip galvanizing), zvakaita sekuumbwa kwesimbi, mamiriro ekunze (senge roughness), kushushikana kwemukati mesimbi, uye saizi dzakasiyana-siyana. Munguva iyi, ukobvu hwesimbi inopisa hunokanganisa ukobvu hwesimbi inopisa (hot-dip galvanizing). Kazhinji, kana plate yacho yakakora, ukobvu hwesimbi inopisa (hot-dip galvanizing) hunokura. Rutsigiro rwayo rwakaita 2.0mm runotorwa semuenzaniso kuratidza kuti inodiwa sei kuti igutse zvinodiwa pakuchengetedza ngura munzvimbo dzakatipoteredza.
Fungidzira kuti ukobvu hwechinhu chinotsigirwa nesimbi i2mm, zvichienderana nechiyero cheGBT13192-2002 chinopisa chegalvanizing.
Upfu hwakadii hwechivharo chepombi yesimbi yakagadzikwa chinodiwa kuti chienderane nezvinodiwa zvehupenyu hwebasa?
Pombi yemativi akavharidzirwa
Zvichienderana nezvinodiwa nemutemo wenyika, ukobvu hwezvinhu zvepasi zve 2mm haufanirwe kunge huri pasi pe 45 μ m. Ukobvu hwakafanana haufanirwe kunge huri pasi pe 55 μ m. Zvichienderana nemhedzisiro yekuyedzwa kwekubuda mumhepo kwakaitwa neJapan Hot Dip Galvanizing Association kubva muna 1964 kusvika 1974. Upfu hwepombi yesimbi yakagadzikwa yakaita sei inodiwa kuti isangane nezvinodiwa zvehupenyu hwese?
Kana zvikaverengerwa zvichienderana nechiyero chenyika, huwandu hwezinc hunosvika 55x7.2=396g/m2,
Hupenyu hwebasa hunowanikwa munzvimbo ina dzakasiyana hunosanganisira:
Nzvimbo huru yeindasitiri: makore 8.91, ine dhigirii yengura yegore negore ye40.1;
Nzvimbo yegungwa: makore 32.67, ine ngura yegore negore ye10.8;
Kunze: makore 66.33, nedhigirii rengura regore negore re5.4;
Nzvimbo yemaguta: makore 20.79, ine dhigirii yegore negore yengura ye17.5
Kana zvikaverengwa zvichienderana nehupenyu hwebasa re photovoltaic hwemakore makumi maviri nemashanu
Zvadaro kutevedzana kwenzvimbo ina ndekwekuti:
1002.5270135437.5, kureva 139 μ m, 37.5 μ m, 18.75 μ m, 60.76 μ m.
Saka, pakupararira kwenzvimbo dzemaguta, ukobvu hwezinc coating hunofanira kunge huri 65 μ M zvine musoro uye zvinodiwa, asi kunzvimbo dzemaindasitiri dzakakura, kunyanya idzo dzine acid nealkali corrosion, zvinokurudzirwa kuti ukobvu hwegalvanized square pipe nezinc coating huwedzeredzwe nemazvo.
