Kodi muyezo wa ASTM wa C channel ndi uti?

Pakumanga ndi kumanga, kugwiritsa ntchito chitsulo cha njira (nthawi zambiri chimatchedwa chitsulo cha C-section) n'kofala kwambiri. Njirazi zimapangidwa ndi chitsulo ndipo zimapangidwa ngati C, ndichifukwa chake dzinalo limatchedwa. Nthawi zambiri zimagwiritsidwa ntchito mumakampani omanga ndipo zimagwiritsidwa ntchito m'njira zosiyanasiyana. Pofuna kuonetsetsa kuti mtundu ndi mawonekedwe a chitsulo cha C-section akusungidwa, bungwe la American Society for Testing and Materials (ASTM) limapanga miyezo ya zinthuzi.

Muyezo wa ASTM waChitsulo chooneka ngati Cimatchedwa ASTM A36. Muyezo uwu umakhudza mawonekedwe a chitsulo cha kaboni chabwino kwambiri chomwe chimagwiritsidwa ntchito pomanga milatho ndi nyumba zomangidwa ndi rivets, bolt kapena welded komanso pazinthu zonse za kapangidwe kake. Muyezo uwu umalongosola zofunikira za kapangidwe kake, mawonekedwe a makina ndi zinthu zina zofunika za chitsulo cha kaboni C-sections.

Chimodzi mwa zofunikira kwambiri za muyezo wa ASTM A36 waChitsulo cha C-channelndi kapangidwe ka mankhwala ka chitsulo chomwe chimagwiritsidwa ntchito popanga. Muyezo umafuna kuti chitsulo chomwe chimagwiritsidwa ntchito pa C-sections chikhale ndi milingo inayake ya kaboni, manganese, phosphorous, sulfure ndi mkuwa. Zofunikira izi zimatsimikizira kuti chitsulo chomwe chimagwiritsidwa ntchito mu C-channel chili ndi zinthu zofunikira kuti chipereke mphamvu ndi kulimba kofunikira pa ntchito yomanga.

Kuwonjezera pa kapangidwe ka mankhwala, muyezo wa ASTM A36 umatchulanso makhalidwe a makina a chitsulo chomwe chimagwiritsidwa ntchito mu chitsulo cha C-section. Izi zikuphatikizapo zofunikira pa mphamvu yotulutsa, mphamvu yokoka komanso kutalika kwa chitsulocho. Makhalidwe amenewa ndi ofunikira kuti chitsulo cha C-channel chikhale ndi mphamvu komanso kusinthasintha kofunikira kuti chipirire katundu ndi kupsinjika komwe kumachitika pa ntchito yomanga.

Muyezo wa ASTM A36 umakhudzanso kulekerera kwa miyeso ndi zofunikira pakuwongoka ndi kupindika kwa chitsulo cha C-section. Mafotokozedwe awa amatsimikizira kuti zigawo za C zopangidwa motsatira muyezo uwu zikukwaniritsa zofunikira za kukula ndi mawonekedwe zomwe zimafunikira kuti zigwiritsidwe ntchito pomanga.

Ponseponse, muyezo wa ASTM A36 wa chitsulo chooneka ngati C umapereka zofunikira zonse pa ubwino ndi magwiridwe antchito a zitsulozi. Potsatira muyezo uwu, opanga amatha kuwonetsetsa kuti zigawo za C zomwe amapanga zikukwaniritsa zofunikira pa ntchito yomanga.

Mwachidule, muyezo wa ASTM waChitsulo cha C-channel, yotchedwa ASTM A36, imatchula zofunikira za kapangidwe ka mankhwala, mawonekedwe a makina, ndi kulekerera kwa chitsulo ichi. Pokwaniritsa zofunikirazi, opanga amatha kupanga zigawo za C zapamwamba zomwe zimakwaniritsa miyezo yofunikira pa ntchito zosiyanasiyana zomanga. Kaya ndi milatho, makina amafakitale kapena nyumba, kutsatira miyezo ya ASTM C-section yachitsulo kumatsimikizira chitetezo ndi kudalirika kwa chitsulo chomwe chimagwiritsidwa ntchito.
