ASTM A153: Chiyero chekupisa-dip galvanized metal parts

Kupisa dip galvanizing ndiyo inonyanya kushandiswa tekinoroji yekudzivirira yezvigadzirwa zvesimbi, iyo inoumba zinc yekuputira pamusoro pesimbi yekudzivirira kuita ngura.Munguva iyi, iyo ASTM A153 yakajairwa yakava gwara rakakosha mumunda wekupisa-dip galvanizing.

Ichi chinyorwa chinopa yakadzama sumo kune zvinoreva, chiyero chekushandisa, uye kukosha kweiyo ASTM A153 standard.

Chii chinonzi ASTM A153?

ASTM A153 chiyero chakagadziridzwa neAmerican Society for Testing and Materials (ASTM International), ine tarisiro yekumisikidza inopisa-dip galvanized simbi hardware.Dhizaini yeiyi chiyero ine chinangwa chekuona kuti inopisa-dip galvanized zvikamu zvinoenderana nenhevedzano yezvakatemerwa uye nzira dzekuyedza kuti ive nechokwadi chekuramba kwecorrosion uye mhando.

Inoshanda scope:

Iyo ASTM A153 yakajairwa inonyanya kushanda kune madiki masimbi, senge mabhaudhi, nzungu, mapini, screws, etc. Inowanzoonekwawo pakati pekubatanidza zvigadzirwa, senge.magokora, tees,uyereducers;Inotsanangura zvidiki zvinodiwa uye zvakatemwa izvo zvikamu izvi zvinofanirwa kuve nazvo panguva inopisa dip galvanizing process.Chinangwa che galvanizing ndechekupa chidziviriro chekudzivirira kudzivirira kukuvara kwesimbi nekuda kwekuora panguva yekushandiswa.

Standard zvinodiwa:

1.Zinc layer ukobvu:

ASTM A153 inotsanangura hushoma ukobvu hwezinc coating.Kazhinji lightweight galvanized, kupa basic corrosion resistance.

2.Application ndima:

Inonyanya kushandiswa munzvimbo dzemukati dzine zvakaderera zvinodikanwa zvekuramba corrosion, senge fenicha, fenzi, hardware yemumba, nezvimwe.

3.Temperature zvinodiwa:

Iyo chaiyo inopisa tembiricha yekushisa inotsanangurwa kuti ive nechokwadi chekutevedzera zviyero.

Nei zvichikosha?

Kukosha kweiyo ASTM A153 yakajairwa ndeyekuti inova nechokwadi chekuti simbi dzakagadzirwa dzakabatwa nemazvo uye dzine kunaka kwekuramba.Izvi zvinobatsira kuwedzera hupenyu hwesevhisi yezvikamu zvesimbi uye kuve nechokwadi chekugara kwavo munzvimbo dzakatarwa dzekushandisa.

Iyo ASTM A153 yakajairwa inoita basa rakakosha mune inopisa dip galvanizing indasitiri.Inopa seti yemirairo yekuona kuti vagadziri uye mainjiniya vanogona kuburitsa simbi zvikamu zvine mhando inoenderana nezviyero.Nekutevera iyi chiyero, zvikamu zvinogadzirwa zvine yakanakisa corrosion kuramba uye inopa yakavimbika simbi zvikamu zvekushandisa kwakasiyana.
