Q345luhlobo lwentsimbi ethambileyo esetyenziswa kakhulu kwiibhulorho, kwizithuthi, kwiinqanawa, kwizakhiwo, kwiinqanawa zoxinzelelo, kwizixhobo ezikhethekileyo, njl.njl., apho u-"Q" uthetha amandla okukhupha, kwaye u-345 uthetha ukuba amandla okukhupha ale ntsimbi yi-345MPa.
Uvavanyo lwentsimbi ye-q345 luquka ikakhulu iinkalo ezimbini: okokuqala, ukuba umxholo wezinto zentsimbi ufikelela kwinqanaba lesizwe; okwesibini, ukuba amandla okuvelisa, uvavanyo lokutsalwa, njl.njl. lwentsimbi luyahlangabezana nemigangatho ngokusebenzisa amaziko obuchwephesha. Inomxholo we-alloy owahlukileyo kwi-q235, eyintsimbi eqhelekileyo yekhabhoni kwaye i-q345 yintsimbi ye-alloy ephantsi.
Uhlu lwezinto ze-Q345
I-Q345 inokwahlulwahlulwa ibe yi-Q345A, i-Q345B, i-Q345C, i-Q345D kunye ne-Q345E ngokwenqanaba. Oko bakumelayo kukuba ubushushu bempembelelo buhlukile. Inqanaba le-Q345A, akukho mpembelelo; Inqanaba le-Q345B, impembelelo yobushushu obuqhelekileyo obungama-20 degrees; Inqanaba le-Q345C, impembelelo ye-0 degrees; Inqanaba le-Q345D, impembelelo ye--20 degrees; Inqanaba le-Q345E, impembelelo ye--40 degrees. Kumaqondo obushushu ahlukeneyo, amaxabiso empembelelo nawo ahlukile.
yahlukile.
Ukusetyenziswa kwezinto ze-Q345
I-Q345 ineempawu ezilungileyo zoomatshini, ukusebenza kakuhle kobushushu obuphantsi, iplastiki elungileyo kunye nokudityaniswa. Isetyenziswa njengeenqanawa zoxinzelelo oluphakathi noluphantsi, iitanki zeoyile, izithuthi, iikhreyini, oomatshini bemigodi, izitishi zamandla, iibhulorho kunye nezinye izakhiwo, iindawo zoomatshini, izakhiwo zezakhiwo, kunye nezakhiwo ngokubanzi ezithwala imithwalo enamandla. Iindawo zesakhiwo sesinyithi, ezisetyenziswa kwiimeko ezishushu okanye eziqhelekileyo, zingasetyenziselwa izakhiwo ezahlukeneyo kwiindawo ezibandayo ezingaphantsi kwe-40°C.
