Ucingo lwensimbi olucindezelwe luyinto eguquguqukayo futhi ebalulekile embonini yokwakha. Lwenziwe ngezinduku zensimbi ezigoqwayo ezishisayo zensimbi enekhabhoni ephezulu eziphathwa ngokushisa futhi zisebenza emakhazeni, lezi zintambo zenzelwe ngokukhethekile ukuhlangabezana nezidingo ezidingayo zokuqinisa ukhonkolo olucindezelwe. Ucingo lwensimbi lunokuqukethwe kwekhabhoni okungu-0.65% kuya ku-0.85%, okuqukethwe kwesulfure ne-phosphorus okungaphansi kuka-0.035%, futhi lunamandla nokuqina okuhle kakhulu.
Ucingo lwensimbi olucindezelwe luthuthuke kakhulu kusukela ekukhiqizweni nasekusetshenzisweni kwalo kwezimboni ngawo-1920. Namuhla, kuye kwakhiwa imikhiqizo eyahlukahlukene efanele ukusetshenziswa okuhlukene futhi enezici ezahlukene. Lokhu kufaka phakathi ucingo oludonswayo olubandayo, ucingo oluqondile, ucingo oluphansi lokuphumula, ucingo oluhlanganisiwe kanye nocingo olunezinti. Le mikhiqizo, ehlanganiswe nezintambo zensimbi ezicindezelwe, isibe yizinhlobo zensimbi ezicindezelwe ezisetshenziswa kakhulu emhlabeni.
Ngokuphathelene nokuhlukaniswa, ucingo lwe-PC olune-serrated oluphansi luyisinqumo esithandwayo. Amandla alo amahle kakhulu okubamba alenza lifaneleke kakhulu ekusetshenzisweni okunengcindezi ephezulu. Ngaphezu kwalokho, ubukhulu bocingo lwensimbi bungu-2.64 mm, okwenza lufanelekele amaphrojekthi ahlukahlukene okwakha. Ngaphezu kwalokho, lolu cingo lwekhonkrithi olucindezelwe ngaphambili luhambisana nezindinganiso ezichazwe ku-1084 SAEJ403, okuqinisekisa ikhwalithi nokuthembeka kwalo.
Esinye sezici eziphawuleka kakhulu zocingo lwensimbi olucindezelwe ngaphambili amandla alo okudonsa angavamile. Ngokuvamile, amandla okudonsa alolu hlobo locingo lwensimbi angaphezu kuka-1470MPa, kancane kancane ashintshela ezingeni lamandla eliyinhloko elingu-1670 ~ 1860MPa. Ngaphezu kwalokho, ububanzi bocingo buye bashintsha ngokuhamba kwesikhathi, kusukela ku-3 kuya ku-5 mm kuya ebangeni lamanje elingu-5 kuya ku-7 mm. Lawa mandla akhuphukile kanye nobubanzi obukhulu kwenza ucingo olucindezelwe ngaphambili lube nokunwebeka kakhulu futhi lukwazi ukumelana nemithwalo emikhulu.
Ngenxa yezakhiwo zayo ezinhle kakhulu, ucingo lwensimbi olucindezelwe lusetshenziswa kabanzi emikhakheni eyahlukene yokwakha. Luvame ukusetshenziselwa ukuqinisa izakhiwo ezifana namabhuloho, izakhiwo kanye nemizila yesitimela ukuze kuthuthukiswe amandla azo okuthwala umthwalo kanye nokuqina kwesakhiwo. Imikhakha yezimboni kanye nengqalasizinda ithembele kakhulu ocingweni lwensimbi olucindezelwe ukuqinisekisa ukuthi amaphrojekthi ayo ahlala isikhathi eside futhi aphephile.
Ngamafuphi, ukuthuthukiswa kocingo lwensimbi olucindezelwe kwaguqula imboni yokwakha. Ukuhlanganiswa kwensimbi esezingeni eliphezulu enekhabhoni ephezulu kanye namasu okusebenza athuthukile kuphumela emikhiqizweni ehlukahlukene efanele ukusetshenziswa okuhlukahlukene. Njengoba kunezinhlobo eziningi zokuhlukanisa kanye nezinketho zosayizi, kanye namandla amahle kakhulu okudonsa kanye nokusetshenziswa okuningi, ucingo lwensimbi olucindezelwe luhlala luyingxenye ebalulekile ekwakheni kwanamuhla.
Isicelo
Njengoba imboni yezinto zensimbi yaseShayina ihamba phambili embonini, ukuhweba ngensimbi kanye ne-logistics kuzwelonke "ibhizinisi elikhulu elinokwethembeka okuhle", amabhizinisi okuhweba ngensimbi yaseShayina, "amabhizinisi azimele ayi-100 aphezulu eShanghai". I-Shanghai Zhanzhi industry Group Co., Ltd., (efinyeziwe ku-Zhanzhi Group) ithatha "Ubuqotho, Ukusebenza, Ukusungula Izinto Ezintsha, Ukunqoba" njengomgomo wayo wokusebenza kuphela, ihlala iqhubeka nokubeka isidingo samakhasimende endaweni yokuqala.
