Niki ASTM isanzwe kumuyoboro wa C?

Mu kubaka no kubaka, gukoresha ibyuma byumuyoboro (bikunze kwitwa C-igice cyuma) birasanzwe. Iyi miyoboro ikozwe mubyuma kandi ikozwe nka C, izina rero. Bikunze gukoreshwa mubikorwa byubwubatsi kandi bifite imikoreshereze myinshi. Kugirango harebwe niba ubuziranenge n'ibisobanuro by'icyuma C-igice gikomeza, Sosiyete y'Abanyamerika ishinzwe ibizamini n'ibikoresho (ASTM) itegura ibipimo ngenderwaho kuri ibyo bicuruzwa.

ASTM isanzwe yaIcyuma C.yitwa ASTM A36. Ibipimo ngenderwaho bikubiyemo imiterere yubuziranenge bwa karubone kugirango ikoreshwe mu iyubakwa ryuzuye, ryubatswe cyangwa risudira ryubaka ibiraro ninyubako kandi mubikorwa rusange. Ibipimo ngenderwaho byerekana ibisabwa mubigize, imiterere yubukanishi nibindi bintu byingenzi biranga ibyuma bya karubone C-bice.

Kimwe mu bintu by'ingenzi bisabwa ASTM A36 isanzwe yaC-umuyoboroni imiti igizwe nicyuma gikoreshwa mugukora. Igipimo gisaba ibyuma bikoreshwa muri C-bice birimo urugero rwa karubone, manganese, fosifore, sulfure n'umuringa. Ibi bisabwa byemeza ko ibyuma bikoreshwa muri C-umuyoboro bifite ibintu nkenerwa kugirango bitange imbaraga nigihe kirekire bisabwa mubikorwa byubaka.

Usibye ibigize imiti, ASTM A36 isanzwe inagaragaza imiterere yubukorikori bwicyuma gikoreshwa mubyuma bya C-gice. Ibi bikubiyemo ibisabwa kugirango umusaruro utangwe, imbaraga zingana no kurambura ibyuma. Iyi mitungo ningirakamaro kugirango tumenye neza ko C-umuyoboro wibyuma ufite imbaraga ningirakamaro bikenewe kugirango uhangane n'imizigo hamwe nihungabana byabaye mubikorwa byo kubaka.

Igipimo cya ASTM A36 gikubiyemo kandi kwihanganira ibipimo no kugororoka no gukenera ibisabwa kuri C -cyuma. Ibi bisobanuro byemeza ko C-ibice byakozwe kuri iki gipimo byujuje ubunini nuburyo bisabwa kugirango bikoreshwe mu mishinga yo kubaka.

Muri rusange, ASTM A36 igipimo cyicyuma cya C gitanga urutonde rwuzuye rwibisabwa kugirango ubuziranenge n'imikorere y'ibyo byuma. Mugukurikiza iyi ngingo ngenderwaho, abayikora barashobora kwemeza ko C-ibice bakora byujuje ibyangombwa bisabwa mubikorwa byubwubatsi.

Muri make, ASTM isanzwe yaC-umuyoboro, izwi nka ASTM A36, yerekana ibisabwa mubigize imiti, imiterere yubukanishi, hamwe no kwihanganira ibipimo byibyuma. Mugukurikiza ibyo bisabwa, ababikora barashobora kubyara C-ibice byujuje ubuziranenge byujuje ubuziranenge busabwa mubikorwa bitandukanye byubwubatsi. Yaba ibiraro, imashini zinganda cyangwa inyubako, yubahiriza ibipimo byibyuma bya ASTM C byerekana umutekano nicyizere cyicyuma cyakoreshejwe.
