Umnatha oshushu-diphu umnatha ucingo, ekwabizwa ngokuba yi-hot-dip galvanized mesh fence, yindlela yokuntywilisela ucingo kwintsimbi etyhidiweyo ukuze kufunyanwe intsimbi. Umnatha wokubiyela wamanzi ashushu-diphu kunye nesinyithi esigqunyiweyo senza i-metallurgical coating ngokuchithwa, ukusabela kweekhemikhali, kunye nokusasazwa. i-alloy layers edibeneyo. Kwiminyaka yakutshanje, ngophuhliso olukhawulezayo lothumelo lwamandla ombane aphezulu, uthutho, kunye nonxibelelwano, iimfuno zokhuseleko lweminatha ye-Guardrail ziye zaba phezulu nangaphezulu, kwaye imfuno ye-hot-dip galvanized guardrail inetha nayo iqhubekile ukwanda. Xa i-hot-dip guardrail iphakanyiswa ngaphandle kwesinyithi esityhidiweyo, isinyithi esinyibilikisiweyo esincanyathiselwe kumphezulu we-alloy layer siyaphola kwaye siqiniswe ibe yingubo. I-alloy layer eyenziwe yi-hot-dip galvanizing inzima kune-substrate ngokwayo, ngoko ayinakonakaliswa lula. Ke ngoko, kukho amandla okudibanisa okuhle phakathi komgangatho oshushu-dip kunye ne-metal substrate. Ukuba ukhetha i-guardrail eya kusetyenziswa ixesha elide, ungasebenzisa kuphela i-galvanized ye-dip eshushu. Nje ukuba utyale imali, akusayi kufuneka uzibuyisele ubomi bakho bonke. Imilo iyafana nenethi enamacala amabini. Into kuphela kukuba umbala awukho luhlaza, kodwa isilivere eqaqambileyo.
Iindlela zokuvelisa kunye nokucubungula:
Ngokwesiko, indlela yonyango yangaphambili isetyenziswa rhoqo. Siyazi ukuba ucingo lwe-mesh yimveliso ekhuselayo. Ekubeni isetyenziswe ngaphandle iminyaka emininzi, indlela yokuthintela ukubola ixesha elide ibe yingxaki ekufuneka isonjululwe. Ngokubanzi, yonke imiphezulu esetyenziswayo ngoku kwiinethi zikaloliwe onguhola wendlela kunye nenethi zikaloliwe zokugada umzila kaloliwe Eyona ndlela ingundoqo yokufaka igalvanizing kukugalela idiphu eshushu, kodwa ezinye iifektri ezincinci nazo zisebenzisa igalvanizing ebandayo.
I-off-line annealing ye-hot-dip galvanizing: Phambi kokuba umnatha wokugada ungene kumgca we-galvanizing wediphu oshushu, uqala uhlaziywe ngokutsha kwaye ufakwe kwisithando somlilo sohlobo olusezantsi okanye isithando somlilo sohlobo lwentsimbi. Ngale ndlela, akukho annealing kumgca galvanizing. Inkqubo iphelile. Phambi kokutshisa-dip galvanizing, umnatha kufuneka igcine intsimbi ecocekileyo ecocekileyo umphezulu osebenzayo ongena oxides kunye nobunye ubumdaka. Le ndlela kukuqala ukususa intsimbi oxide isikali kumphezulu umnatha guardrail annealed by pickling, uze usebenzise umaleko zinc chloride okanye isinyibilikisi eyakhiwe umxube ammonium chloride kunye zinc chloride ukukhusela. Thintela umnatha we-guardrail ekubeni ufakwe i-oxidized kwakhona.
Izinto ezilungileyo zokubiyela umnatha oshushu-dip
1. Iindleko zonyango: Iindleko ze-hot-dip galvanizing zokuthintela umhlwa zingaphantsi kunezinye iipeyinti zepeyinti;
2. Ihlala ixesha elide: Kwiimeko ezingqongileyo zasezidolophini, umaleko oqhelekileyo wokuchasa umhlwa oshushu-dip ungahlala ngaphezu kweminyaka engama-50 ngaphandle kokulungiswa; kwiindawo ezisezidolophini okanye ezikude nonxweme, umgangatho we-Qingli guardrail womzi-mveliso oshushu-dip wagalvanized anti-rust layer ungahlala ngaphezulu kweminyaka engama-50. Ihlala iminyaka engama-20 ngaphandle kokuphinda ihlaziywe;
3. Ukuthembeka okulungileyo: I-galvanized layer kunye nentsimbi ihlanganiswe nge-metallurgically kwaye ibe yinxalenye yentsimbi yentsimbi, ngoko ke ukuqina kwengubo kunokwethenjelwa;
4. Isigqubuthelo sinokuqina okuqinileyo: I-zinc yokugubungela yenza isakhiwo esikhethekileyo se-metallurgical, esinokumelana nomonakalo womatshini ngexesha lokuthutha kunye nokusetyenziswa;
5. Ukukhuselwa okubanzi: Yonke inxalenye yamacandelo adibeneyo anokuthi afakwe nge-zinc, nakwii-depressions, iikona ezibukhali kunye neendawo ezifihlakeleyo, zinokukhuselwa ngokupheleleyo;
6. Gcina ixesha kunye nomgudu: Inkqubo ye-galvanizing ikhawuleza kunezinye iindlela zokwakha zokugquma, kwaye inokuphepha ixesha elifunekayo lokupeyinta kwindawo yokwakha emva kokufakwa. Umphezulu we-hot-dip galvanizing umhlophe, inani le-zinc likhulu, kwaye ixabiso libiza kakhulu. Ngokubanzi, kukho iigalvanized ezininzi eziditshiweyo, ezinemibala eyahlukeneyo kunye neempawu ezilungileyo zokuchasana nomhlwa.
Ukusetyenziswa okuphambili: Kusetyenziswa ngokubanzi ukhuseleko lokhuseleko kwindawo yodwa yokhuseleko lohola wendlela, oololiwe, izikhululo zeenqwelo moya, iindawo zokuhlala, iifektri kunye nemigodi, iindawo zokwakha zethutyana, amazibuko kunye neetheminali, iigadi, iindawo zokutya, ukuvalwa kweentaba kunye neendawo zokukhusela amahlathi.
