1.1 Iplastiki
I-Plastiki yikhono lezinto zetsimbi ukuvelisa i-deformation yeplastiki (i-deformation esisigxina) phantsi komthwalo ngaphandle komonakalo.
1.2 Ukuqina
Ukuqina kukwalatha kwinqanaba lokuqina okanye ukuthamba kwemathiriyeli yesinyithi.Eyona ndlela ixhaphakileyo esetyenziswayo ekumiseleni ubulukhuni kwimveliso yindlela yobulukhuni bokungena, esebenzisa i-indenter yejometri ethile ukucinezela kumphezulu wemathiriyeli yentsimbi evavanyiweyo phantsi komthwalo othile kwaye imisela ixabiso lobulukhuni bayo ngokwenqanaba lokucinezelwa. kuyo.
Iindlela ezisetyenziswa ngokuqhelekileyo ziiBrinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) kunye neendlela zeVickers hardness (HV).
1.3 Ukudinwa
Amandla, iplastiki kunye nokuqina okuxoxwe ngaphambili zonke zizalathisi kwiipropati zemishini yesinyithi phantsi komthwalo omileyo.Ngapha koko, uninzi lwamalungu omatshini asebenza phantsi komthwalo we-cyclic, kwaye phantsi kweemeko ezinjalo amalungu avelisa ukudinwa.
1.4 Ukuqina kwempembelelo
Umthwalo osebenza kwindawo yomatshini ngesantya esikhulu ubizwa ngokuba ngumthwalo wempembelelo, kwaye ukukwazi kwesinyithi ukuxhathisa umonakalo phantsi komthwalo wempembelelo kubizwa ngokuba yimpembelelo yokuqina.
1.5 Amandla
Amandla kukuchasana kwezinto zetsimbi ukulimaza (i-deformation yeplastiki egqithisileyo okanye i-fracture) phantsi komthwalo we-static.Njengoko isenzo somthwalo ngendlela yokuqina, ukunyanzeliswa, ukugoba, ukucheba, ngoko ke amandla ahlulahlulwe abe ngamandla okuqina, amandla acinezelayo, amandla okugoba, amandla okucheba, njl njl. ukusetyenziswa kwamandla okuqina ngokubanzi njengesona salathisi samandla esisisiseko.
Ityhubhu yesikwere isetyenziselwa ulwakhiwo, ukuveliswa koomatshini, iiprojekthi zolwakhiwo lwentsimbi, ukwakhiwa kweenqanawa, inkxaso yokuvelisa amandla elanga, ubunjineli besakhiwo sentsimbi, ubunjineli bamandla, izityalo zamandla, oomatshini bezolimo kunye neekhemikhali, iindonga zeglasi lomkhusane, i-chassis yemoto, izikhululo zeenqwelo moya, ukwakhiwa kwebhoyila, iintsimbi zendlela. , ukwakhiwa kwezindlu, iinqanawa zoxinzelelo, iitanki zokugcina i-petroleum, iibhulorho, izixhobo zesikhululo samandla, ukunyusa kunye noomatshini bokuthutha kunye nezinye iindawo eziphezulu ezidibeneyo zesakhiwo, njl.
Ukuhlelwa kwenkqubo
ityhubhu yesikwere ihlelwa ngokwenkqubo yemveliso: ityhubhu eshushu eqengqelekayo engenamthungo, ityhubhu yesikwere epholileyo etsalwayo, ityhubhu edityanisiweyo yesikwere, ityhubhu edibeneyo yesikwere.
Phakathi kwabo, ityhubhu edibeneyo yesikwere yahlulwe
1. ngokwenkqubo - i-arc welding square tube, ukumelana ne-welding square tube (i-frequency ephezulu, i-frequency ephantsi), i-gas welding square tube, i-furnace welding square tube.
2. ngokomthungo we-welding - umthungo othe tye we-welded square pipe, i-spiral welded square pipe.
Ukuhlelwa kwezinto
Umbhobho we-square ngezinto eziphathekayo: umbhobho we-carbon steel square, umbhobho ophantsi we-alloy square.
1. Plain carbon steel yahlulwe: Q195, Q215, Q235, SS400, 20 # intsimbi, 45 # intsimbi, njl.
2. Insimbi ye-alloy ephantsi ihlukaniswe: Q345, 16Mn, Q390, ST52-3, njl.
Ukuhlelwa komgangatho wemveliso
ityhubhu yesikwere ngokwemigangatho yemveliso: ityhubhu esemgangathweni yesizwe, ityhubhu yesikwere esiseJapan, ityhubhu yesikwere sobukhosi, ityhubhu yesikwere esiqhelekileyo saseMelika, ityhubhu yesikwere esiqhelekileyo saseYurophu, ityhubhu yesikwere esingengawo.
Ukuhlelwa kwemilo yecandelo
Ityhubhu yesikwere ngokwemilo yolwahlulo lwecandelo.
1. I-tube yesikwere yecandelo elilula: ityhubhu yesikwere yesikwere, i-rectangular square tube.
2. I-tube yesikwere yecandelo eliyinkimbinkimbi: ityhubhu yesikwere sentyatyambo, ityhubhu yesikwere evulekileyo, ityhubhu yesikwere edibeneyo, ityhubhu yesikwere emile.
Ukuhlelwa konyango olungaphezulu
ityhubhu square ngokonyango umphezulu: diphu eshushu ityhubhu square galvanized, electro galvanized square tube, oiled square tube, pickled square tube.
Sebenzisa ulwahlulo
