Nyenzo za kawaida za vifungo vya mfululizo wa DIN
Vifungo vya mfululizo wa DIN havipunguki kwa chuma cha pua, vinaweza kufanywa kutoka kwa vifaa mbalimbali vya chuma. Vifaa vya kawaida vya utengenezaji wa vifungo vya mfululizo wa DIN ni pamoja na:
Chuma cha pua
Inafaa kwa matumizi ambapo upinzani wa kutu unahitajika, kama vile vifaa vya nje, vifaa vya kemikali, na tasnia za usindikaji wa chakula. Mifano ya kawaida ni 304 na 316 chuma cha pua.
Chuma cha kaboni
Vifunga vya chuma vya kaboni vina nguvu ya juu na gharama ya chini, na vinafaa kwa matumizi kama vile mashine na ujenzi ambapo upinzani wa kutu hauhitajiki. Chuma cha kaboni cha darasa tofauti za nguvu kinaweza kuchaguliwa kulingana na matumizi maalum.
Aloi ya chuma
Inatumika katika programu zinazohitaji nguvu ya juu na upinzani wa kuvaa, katika miunganisho ya mitambo yenye mkazo wa juu, kawaida hutibiwa joto ili kuongeza nguvu zake.
Aloi za shaba na shaba
Kwa sababu aloi za shaba na shaba zina conductivity nzuri ya umeme na upinzani wa kutu, vifungo vinavyotengenezwa kutoka kwao ni vya kawaida zaidi katika vifaa vya umeme au maombi ya mapambo. Hasara ni nguvu ya chini.
Mabati ya chuma
Chuma cha kaboni hutiwa mabati ili kuongeza upinzani wake wa kutu, ambayo ni chaguo la kawaida na inafaa hasa kwa matumizi ya nje na katika mazingira ya unyevu.
Mbinu zako za usafiri ni zipi?
Tunakupa njia zifuatazo za usafiri ambazo unaweza kuchagua kutoka:
Usafiri wa baharini
Inafaa kwa bidhaa nyingi na usafiri wa umbali mrefu, kwa gharama ya chini na muda mrefu wa usafiri.
Usafiri wa anga
Inafaa kwa bidhaa ndogo zilizo na mahitaji ya juu ya wakati, kasi ya haraka, lakini gharama ya juu.
Usafiri wa nchi kavu
Hutumika zaidi kwa biashara kati ya nchi jirani, zinazofaa kwa usafiri wa masafa ya kati na mafupi.
Usafiri wa reli
Kawaida hutumika kwa usafirishaji kati ya Uchina na Uropa, kwa wakati na gharama kati ya usafirishaji wa baharini na usafirishaji wa anga.
Uwasilishaji wa moja kwa moja
Inafaa kwa bidhaa ndogo za haraka, zenye gharama ya juu, lakini kasi ya uwasilishaji na uwasilishaji rahisi wa mlango hadi mlango.
Ni njia gani ya usafiri unayochagua inategemea aina ya mizigo yako, mahitaji ya wakati na bajeti ya gharama.
