◉Okuvamileiladi lekhebulaUmehluko wohlobo ikakhulukazi usentweni kanye nokuma, izinhlobonhlobo zezinto kanye nokwakheka kuhambisana nezimo ezahlukahlukene zokusebenza.
Ngokuvamile, indaba yeiladi lekhebulangokuyisisekelo ukusetshenziswa kwensimbi evamile ye-carbon structural steel Q235B, le nto kulula ukuyithola futhi eshibhile, izakhiwo ezinzile kakhulu zemishini, ukwelashwa kwendawo noma umphumela wokunamathela kuhle kakhulu. Futhi kwezinye izimo ezikhethekile zokusebenza, kuphela ukusebenzisa ezinye izinto.
◉Umkhawulo wesivuno se-Q235B ngu-235MPA, impahla inokuqukethwe kwekhabhoni ephansi, eyaziwa nangokuthi insimbi ye-carbon ephansi. Ukuqina okuhle, okulungele ukwelula nokugoba nokunye ukucubungula okubandayo, ukusebenza kwe-welding nakho kuhle kakhulu. I-side rails kanye ne-crossbar ye-iladi lekhebulaidinga ukugoba ukuze kuqiniswe ukuqina kwayo, iningi lezixhumanisi ezimbili nazo zishiselwe, le nto ifanele izimo zokusebenza zeladi lekhebula.
◉Ukuze kuqinisekiswe ukuthi ikhwalithi ebusweni umkhiqizo kanye ukumelana ukugqwala, jikelele ikhebula iladi uma ukusetshenziswa omnene ukukhiqizwa steel kanye yokukhiqiza, kodwa futhi kudingeka afeze ukwelashwa surface. Ngokombono wokusetshenziswa kwemvelo, iningi lesitebhisi sekhebula lisetshenziswa ngaphandle, ingxenye encane kakhulu yokusetshenziswa kwangaphakathi. Ngale ndlela, iladi lekhebula elenziwe nge-carbon steel elakhiwe ngokujwayelekile lizosebenzisa i-hot-dip galvanized surface treatment, ukushuba kwe-zinc layer ngokuvamile kuyisilinganiso esingama-50 ~ 80 μm endaweni evamile yangaphandle, ngokusho konyaka ukuze kudle ukushuba kwe-zinc layer ka-5. μm isilinganiso sokubala, singaqinisekisa ukuthi iminyaka engaphezu kwe-10 ayigqwali. Ngokuyisisekelo, ingahlangabezana nezidingo zokwakhiwa okuningi kwangaphandle. Uma isikhathi eside sokuvikela ukugqwala sidingeka, ubukhulu bengqimba ye-zinc budinga ukwanda.
◉Isetshenziswa endaweni yangaphakathi yendluiladi lekhebulangokuvamile izosebenzisa ukukhiqizwa kwe-aluminium, futhi i-aluminium ebandayo yokucubungula ukugoba nokusebenza kwe-welding akulungile, uma sikhuluma nje, ama-rails asemaceleni kanye ne-crossbar kuzosebenzisa indlela yokubumba i-mold extrusion ukucubungula. Ukuxhumana phakathi kokubili kuzosebenzisa ama-bolts noma ama-rivets ukuxhuma nokulungisa, yiqiniso, amanye amaphrojekthi azodinga indlela yokushisela ukuze kuxhunywe.
◉I-aluminium surface ingamelana nokugqwala, kodwa uma sikhuluma nje, ukuze ibe yinhle, i-aluminium eyenziwe ngeladi lekhebula izoba ukwelashwa kwe-oxidation ngaphezulu. Ukumelana nokugqwala kwe-aluminium oxidation kunamandla kakhulu, ngokuyisisekelo ukusetshenziswa kwasendlini kungaqinisekiswa iminyaka engaphezu kwe-10 ngeke kuvele into yokugqwala, ngisho nangaphandle nakho kungafinyelela le mfuneko.
◉Izindleko zesitebhisi sekhebula lensimbi engagqwali ziphakeme, ezifanele ezinye zemvelo yizimo zokusebenza ezikhethekile kakhulu. Njengemikhumbi, izibhedlela, izikhumulo zezindiza, izitshalo zikagesi, imboni yamakhemikhali nokunye. Ngokwezidingo eziphakeme neziphansi, ngokulandelana, i-SS304 noma i-SS316 impahla. Uma udinga ukufaka isicelo endaweni enzima kakhulu, njengamanzi olwandle angapheli noma ukuguguleka kwempahla yamakhemikhali, ungasebenzisa impahla ye-SS316 ukuze ukhiqize iledi yekhebula ngemva kobuso bese ifakwa nge-nickel, ingakhuphula kakhulu ukumelana nokugqwala.
◉Njengamanje, imakethe ngaphezu kwalezi zinto ezishiwo ngenhla kanye nokwelashwa kwendawo, kunezinye izinto ezibandayo, njengeladi lekhebula lepulasitiki eliqiniswe ngengilazi, elisetshenziswa kakhulu kwenye iphrojekthi yokuvikela umlilo efihliwe. Lokhu kwaziswa kufanele kukhethwe ngokwezidingo zephrojekthi.
◉Impahla yesitebhisi sekhebula eshiwo ngenhla kanye nezidingo zokwelashwa kwendawo, ngenkomba kuphela.
