Kodi SS400 ndi chiyani? Kodi chitsulo cha m'nyumba chofanana ndi SS400 ndi chiyani?

SS400Ndi mbale yachitsulo yokhazikika ya kaboni yaku Japan yogwirizana ndi JIS G3101. Ikugwirizana ndi Q235B mu muyezo wadziko lonse waku China, yokhala ndi mphamvu yokoka ya 400 MPa. Chifukwa cha kuchuluka kwa kaboni pang'ono, imapereka mawonekedwe abwino, zomwe zimapangitsa kuti ikhale yogwirizana bwino pakati pa mphamvu, kusinthasintha, ndi kusinthasintha, zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri.
Kusiyana pakati paQ235b Ss400:

Miyezo Yosiyana:
Q235Bikutsatira Chinese National Standard (GB/T700-2006). “Q” ikutanthauza mphamvu yobereka, '235' ikusonyeza mphamvu yobereka yocheperako ya 235 MPa, ndipo “B” ikutanthauza mtundu wa khalidwe. SS400 ikutsatira Japanese Industrial Standard (JIS G3101), pomwe “SS” ikutanthauza chitsulo chomangira ndipo “400” ikusonyeza mphamvu yobereka yoposa 400 MPa. Mu zitsanzo za mbale zachitsulo za 16mm, SS400 imasonyeza mphamvu yobereka yoposa 10 MPa kuposa Q235A. Mphamvu yobereka ndi kutalika konse kumaposa Q235A.

 

Makhalidwe Ogwira Ntchito:

Mu ntchito zenizeni, mitundu yonse iwiri imagwira ntchito mofanana ndipo nthawi zambiri imagulitsidwa ndikukonzedwa ngati chitsulo cha kaboni wamba, ndipo kusiyana sikuonekera bwino. Komabe, kuchokera ku tanthauzo lokhazikika, Q235B imagogomezera mphamvu yokolola, pomwe SS400 imaika patsogolo mphamvu yokoka. Pa mapulojekiti omwe ali ndi zofunikira mwatsatanetsatane za kapangidwe ka makina achitsulo, kusankha kuyenera kutengera zosowa zinazake.

 

Ma plate achitsulo a Q235A ali ndi mitundu yocheperako yogwiritsidwa ntchito kuposa SS400. SS400 kwenikweni ndi yofanana ndi Q235 yaku China (yofanana ndi kagwiritsidwe ntchito ka Q235A). Komabe, zizindikiro zina zimasiyana: Q235 imatchula malire a zinthu monga C, Si, Mn, S, ndi P, pomwe SS400 imangofuna kuti S ndi P zikhale zochepa kuposa 0.050. Q235 ili ndi mphamvu yotulutsa yoposa 235 MPa, pomwe SS400 imapeza 245 MPa. SS400 (chitsulo cha kapangidwe kake) imayimira chitsulo chomangira chomwe chili ndi mphamvu yomangika yoposa 400 MPa. Q235 imayimira chitsulo chomangira cha kaboni chomwe chili ndi mphamvu yotulutsa yoposa 235 MPa.

 

Kugwiritsa Ntchito SS400: SS400 nthawi zambiri imakulungidwa mu ndodo za waya, mipiringidzo yozungulira, mipiringidzo yozungulira, mipiringidzo yosalala, mipiringidzo ya ngodya, mipiringidzo ya I, magawo a njira, chitsulo cha chimango cha zenera, ndi mawonekedwe ena a kapangidwe, komanso mbale zokhuthala pakati. Imagwiritsidwa ntchito kwambiri m'milatho, zombo, magalimoto, nyumba, ndi nyumba zaukadaulo. Imagwira ntchito ngati mipiringidzo yolimbitsa kapena yopangira ma trus a denga la fakitale, nsanja zotumizira zamagetsi amphamvu, milatho, magalimoto, ma boiler, makontena, zombo, ndi zina zotero. Imagwiritsidwanso ntchito kwambiri pazigawo zamakanika zomwe sizimafunikira mphamvu zambiri. Zitsulo za Giredi C ndi D zitha kugwiritsidwanso ntchito pazinthu zina zapadera.
