ASTM A283 vs ASTM A709: Kusiyana Kwakukulu mu Kapangidwe ka Mankhwala, Kapangidwe ka Makina, ndi Kugwiritsa Ntchito

Pamene ndalama zogulira zomangamanga padziko lonse lapansi zikupitirira kukwera, makontrakitala, opanga zitsulo, ndi magulu ogula zinthu akuganizira kwambiri kusiyana kwa magwiridwe antchito pakati pa miyezo yosiyanasiyana ya kapangidwe ka zitsulo.ASTM A283ndiASTM A709ndi miyezo iwiri ya mbale zachitsulo zomwe zimagwiritsidwa ntchito kwambiri, iliyonse ili ndi makhalidwe osiyana malinga ndi kapangidwe ka mankhwala, mawonekedwe a makina, ndi ntchito zake. Nkhaniyi ikupereka kufananiza kwakuya kwa akatswiri pantchito yomanga milatho, nyumba zomangira, ndi mapulojekiti amafakitale.

ASTM A283: Chitsulo Chopangira Kapangidwe ka Carbon Chotsika Mtengo

ASTM A283ndi muyezo wa mbale yachitsulo yopangidwa ndi kaboni yomwe imagwiritsidwa ntchito kwambiri pa ntchito zomanga ndi uinjiniya. Ubwino wake ndi monga:

Yotsika mtengo komanso yotsika mtengo

Kutha kusweka bwino komanso kugwira ntchito bwino

Yoyenera kugwiritsidwa ntchito popanga nyumba zolimba kwambiri

Magiredi ofanana akuphatikizapo A283 Giredi A, B, C, ndi D, ndiGiredi Cndi omwe amagwiritsidwa ntchito kwambiri. Ntchito zambiri zimaphatikizapo matanki osungiramo zinthu, zida zopepuka, mbale zomangira, ndi zida zosafunikira kwambiri.

Ponena za kapangidwe ka mankhwala, A283 ndi chitsulo chopanda mpweya wambiri chokhala ndi zinthu zosavuta komanso chopanda aloyi yowonjezera, zomwe zimapangitsa kuti chikhale chotsika mtengo koma chosakhala champhamvu komanso cholimba.

ASTM A709: Chitsulo Champhamvu Kwambiri cha Mlatho

Mosiyana ndi zimenezi, ASTM A709 ndi yothandiza kwambiri.muyezo wachitsulo chomangidwa womwe wapangidwira makamaka kumanga mlatho, yomwe imagwiritsidwa ntchito kwambiri pa milatho yamisewu ikuluikulu ndi ya sitima, kuphatikizapo matabwa akuluakulu, matabwa opingasa, mbale za padenga, ndi nyumba zomangira.

Magiredi wamba ndi awa:

A709 Giredi 36

A709 Giredi 50

A709 Giredi 50W (chitsulo chotenthetsera)

HPS 50W / HPS 70W (chitsulo chogwira ntchito bwino kwambiri)

Ubwino waukulu wa A709 ndi monga:

Mphamvu yochuluka yokolola (≥345 MPa ya Giredi 50)

Kulimba kwabwino kwambiri kutentha kotsika kuti muchepetse kutopa ndi kukana kukhudzidwa

Kukana nyengo mwakufuna kuti muchepetse ndalama zosamalira nthawi yayitali

Chitsulo chapamwamba ichi chimapangitsa A709 kukhala yoyenera kwambiri pa milatho yayitali, nyumba zolemera, ndi mapulojekiti omwe amafunikira kulimba motsutsana ndi dzimbiri mumlengalenga.

Kuyerekeza kwa Katundu wa Makina

Katundu ASTM A283 Giredi C ASTM A709 Giredi 50
Mphamvu Yopereka ≥ 205 MPa ≥ 345 MPa
Kulimba kwamakokedwe 380–515 MPa 450–620 MPa
Kulimba kwa Impact Wocheperako Zabwino kwambiri (zoyenera milatho)
Kukana kwa Nyengo Muyezo Magiredi a nyengo 50W/HPS

A709 imapereka mphamvu, kulimba, komanso kulimba kwapamwamba kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pakugwiritsa ntchito zinthu zambiri komanso zofunika kwambiri.

Zoganizira za Mtengo

Chifukwa cha zinthu zina zowonjezera komanso zofunikira pakugwira ntchito bwino,Kawirikawiri A709 ndi yokwera mtengo kuposa A283Kwa mapulojekiti omwe amaganizira bajeti yawo omwe akufunafuna nyumba zochepa, A283 imapereka ndalama zogwiritsira ntchito bwino kwambiri. Komabe, pomanga milatho ndi nyumba zonyamula katundu wambiri, A709 ndiye chinthu chomwe chimakondedwa kapena cholamulidwa.

 

Akatswiri a zauinjiniya akugogomezera kusankha mtundu woyenera wa chitsulo kutengera zofunikira pa kapangidwe kake osati mtengo wokha.

Mapulojekiti olemera pang'ono, osafunikira kwenikweni: A283 ndi yokwanira.

Milatho, nyumba zazitali, katundu wotopa kwambiri, kapena kukhudzana ndi malo ovuta: A709 ndiyofunikira.

Pamene chitukuko cha zomangamanga padziko lonse chikufulumira, kufunikira kwa ASTM A709 kukupitirira kukula, pomwe A283 ikadali yokhazikika m'misika yomanga nyumba ndi matanki.

 

Lumikizanani nafe kuti mudziwe zambiri.
