Ngenxa yenkqubela phambili eqhubekayo kuluntu, indlela yemveli yokuvelisa ezolimo ayisakwazi ukuhlangabezana neemfuno zophuhliso lwempucuko yanamhlanje, kwaye ezolimo ezintsha zifunwa ngabantu abakwishishini. Enyanisweni, izixhobo zezolimo ezibizwa ngokuba zizixhobo zezolimo ikakhulu zizixhobo zegreenhouse. Azithintelwa lixesha nendawo. Zingenza imveliso yezolimo kwiindawo ezikhethekileyo ezifana nethafa, intaba enzulu kunye nentlango. Njengomthombo weprojekthi yegreenhouse, izixhobo kufuneka zilawule umgangatho weprojekthi, okokuqala, ekukhetheni izixhobo. Umzekelo, kwizinto zentsimbi ezisetyenzisiweyo kwiprojekthi yegreenhouse, intsimbi esemgangathweni ophezulu iya kucutshungulwa kwaye isuswe. Emva kokufakelwa i-hot plating kwisityalo sobuchwephesha se-galvanizing, isebe lokuhlola umgangatho liya kuyivavanya kwakhona. Emva kokuphumelela uvavanyo, iya kuthuthwa iye kwindawo yokwakha ukuze isetyenziswe.

1. Ulwakhiwo lombhobho wentsimbi egalelweyo eshushu: umbhobho wentsimbi egalelweyo eshushu kukwenza isinyithi esinyibilikisiweyo sisebenze kunye ne-iron matrix ukuvelisa umaleko we-alloy, ukuze kudityaniswe i-matrix kunye ne-coating. Umbhobho we-hot-dip galvanized obonelelwa yiTianjin Feilong Pipe Co., Ltd. uqala ngokugalelwa. Ukuze kususwe i-iron oxide kumphezulu wombhobho wentsimbi, emva kokugalelwa, icocwa nge-ammonium chloride okanye i-zinc chloride aqueous solution okanye i-ammonium chloride kunye ne-zinc chloride mixed aqueous solution tank, ize ithunyelwe kwi-hot-dip galvanizing tank. I-hot dip galvanizing ineengenelo zokugalelwa okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. I-matrix yombhobho wentsimbi egalelweyo eshushu ineempendulo zomzimba kunye neekhemikhali ezintsonkothileyo kunye nesisombululo se-molded plating ukuze yenze umaleko we-zinc ferroalloy onganyangekiyo nokugqwala onesakhiwo esincinci. Umaleko we-alloy udityaniswe nomaleko we-zinc ococekileyo kunye ne-iron pipe matrix. Ke ngoko, inokumelana okunamandla kokugqwala.

2. Ulwakhiwo lombhobho we-galvanized strip: umbhobho we-galvanized strip ulungisa inkqubo yokuveliswa kombhobho we-galvanized otshisiweyo. Okokuqala, intsimbi ye-strip esetyenziselwa ukwenza umbhobho kufuneka ihluzwe ukuze kususwe i-iron oxide kumphezulu wentsimbi ye-strip. Emva koko yomise ngomoya uze wenze umbhobho. Ingubo iyafana kwaye ikhanya, kwaye ubungakanani be-zinc plating buncinci, nto leyo iphantsi kuneendleko zokuvelisa umbhobho we-galvanized otshisiweyo otshisiweyo. Ukumelana kwayo nokugqwala kubi kancinci kunombhobho we-galvanized otshisiweyo otshisiweyo.
