Ngenkqubela phambili eqhubekayo yoluntu, indlela yemveli yemveliso yezolimo ayinakukwazi ukuhlangabezana neemfuno zophuhliso lwempucuko yanamhlanje, kwaye indawo entsha yezolimo ifunwa ngabantu abakushishino. Enyanisweni, oko kubizwa ngokuba yizixhobo zezolimo ubukhulu becala izibonelelo ze-greenhouse. Ayikhawulelwanga lixesha kunye nendawo. Iyakwazi ukwenza imveliso yezolimo kwiindawo ezikhethekileyo ezifana nethafa, intaba enzulu kunye nentlango. Njengomthombo weprojekthi ye-greenhouse, izinto kufuneka zilawule umgangatho weprojekthi, okokuqala, ekukhethweni kwezinto. Ngokomzekelo, kwiingxenye zetsimbi ezisetyenziswe kwiprojekthi ye-greenhouse, insimbi ephezulu iya kucutshungulwa kwaye ichithwe. Emva kokugquma okushushu kwiplanti yokugalela intsimbi, isebe lokuhlola umgangatho liza kuphinda livavanye. Emva kokuphumelela uvavanyo, iya kuthuthelwa kwindawo yokwakha ukuze isetyenziswe.

1. Idiphu eshushu yesakhiwo sombhobho wentsimbi: idiphu eshushu umbhobho owenziwe ngamazimba kukwenza isinyithi esinyibilikisiweyo sisabelane nentsimbi ye-matrix ukuvelisa umaleko wealloyi, ukuze kudityaniswe i-matrix kunye nokwaleka. Umbhobho owenziwe ngezinki oshushu-diphu obonelelwa yi-Tianjin Feilong Pipe Co., Ltd. Ukuze ukususa intsimbi oxide kumphezulu umbhobho yentsimbi, emva pickling, icocwe ammonium chloride okanye zinc chloride isisombululo aqueous okanye ammonium chloride kunye nezinki chloride exutywe nesisombululo aqueous itanki, kwaye emva koko ithunyelwe kwitanki eshushu-dip galvanizing. I-Hot dip galvanizing ineenzuzo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. I-matrix yombhobho wesinyithi owenziwe ngesinyithi oshushu-diphu ineempendulo ezintsonkothileyo zomzimba kunye neekhemikhali kunye nesisombululo esinyibilikisiweyo se-plating ukwenza umaleko we-zinc ferroalloy onganyangekiyo kunye nesakhiwo esixineneyo. Uluhlu lwe-alloy luhlanganiswe kunye ne-zinc ecocekileyo kunye ne-matrix yombhobho wensimbi. Ngoko ke, inokumelana ne-corrosion enamandla.

2. Ulwakhiwo lwemibhobho yombhobho wegalvanized: umbhobho we-galvanized strip ulungelelanisa inkqubo yokuvelisa umbhobho oshushu wokudipha. Okokuqala, umcu wentsimbi osetyenziselwa ukwenza umbhobho uya kucholwa ukuze kususwe i-iron oxide kumphezulu wentsimbi yomtya. Emva koko umoya womile kwaye wenze umbhobho. Ukugquma kuyafana kwaye kuqhakazile, kwaye inani le-zinc plating lincinci, eliphantsi kuneendleko zokuvelisa umbhobho we-galvanized we-hot-dip. Ukunganyangeki komhlwa kumbi kancinane kunombhobho owenziwe yizinki oshushu
