Ngokuqhubeka okuqhubekayo komphakathi, indlela yokukhiqiza yezolimo evamile ngeke isakwazi ukuhlangabezana nezidingo zokuthuthukiswa kwempucuko yesimanje, futhi isikhungo esisha sezolimo sifunwa ngabantu abasembonini. Eqinisweni, lokho okubizwa ngokuthi imishini yezolimo ikakhulukazi izikhungo ezibamba ukushisa. Ayinqunyelwe isikhathi nendawo. Ingakwazi ukwenza ukukhiqizwa kwezolimo ezindaweni ezikhethekile ezifana nethafa, intaba ejulile kanye nogwadule. Njengomthombo wephrojekthi ye-greenhouse, izinto ezisetshenziswayo kufanele zilawule ikhwalithi yephrojekthi, okokuqala, ekukhethweni kwezinto zokwakha. Isibonelo, ezingxenyeni zensimbi ezisetshenziswe kuphrojekthi ye-greenhouse, insimbi yekhwalithi ephezulu izocutshungulwa futhi ichithwe. Ngemuva kokufakwa okushisayo embonini yokufaka umpheme, umnyango wokuhlola ikhwalithi uzophinde uyihlole. Ngemva kokuphumelela ukuhlolwa, izothuthelwa endaweni yokwakha ukuze isetshenziswe.

1. Isakhiwo sepayipi lensimbi elishisayo lediphu elishisayo: idiphu elishisayo ipayipi elenza insimbi encibilikisiwe isabelane ne-iron matrix ukukhiqiza ungqimba lwe-alloy, ukuze kuhlanganiswe i-matrix nokunamathela. Ipayipi elinothayela lediphu elishisayo elihlinzekwa yi-Tianjin Feilong Pipe Co., Ltd. liqale lifakwe emanzini anosawoti. Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, ihlanzwa nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe ne-aqueous solution tank, bese ithunyelwa ethangini elishisayo lokucwilisa. I-hot dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi. I-matrix yepayipi lensimbi elidiphu elishisayo linokuhlangana okuyinkimbinkimbi ngokomzimba namakhemikhali nesisombululo sokucwenga esincibilikisiwe ukwenza ungqimba lwe-zinc ferroalloy olungagqwali olunesakhiwo esihlangene. Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi. Ngakho-ke, inokumelana nokugqwala okuqinile.

2. Isakhiwo sepayipi eliphehla uthayela: ipayipi eliwuthayela lilungisa inqubo yokukhiqiza ipayipi elinothayela elishisayo. Okokuqala, insimbi yomugqa esetshenziselwa ukwenza amapayipi kufanele ifakwe emanzini ukuze kukhishwe i-iron oxide ebusweni bensimbi yomugqa. Bese womisa umoya bese wenza ipayipi. I-coating iyunifomu futhi igqamile, futhi inani le-zinc plating lincane, eliphansi kunezindleko zokukhiqiza ipayipi lama-galvanized dip-dip. Ukumelana nokugqwala kwayo kubi kakhulu kunepayipi elinothayela lediphu elishisayo
