Muindasitiri yezvigadzirwa zvesimbi, hot-dip galvanizing yakajairika anti-corrosion process.ASTM A153 uye ASTM A123 ndiwo mazinga maviri makuru anogadzirisa zvinodiwa uye maitiro ekupisa-dip galvanizing.Ichi chinyorwa chichasuma kufanana uye mutsauko pakati pezviyero zviviri izvi kubatsira vashandi vemuindasitiri kunzwisisa zviri nani mutsauko uripo pakati pawo.
Kupisa dip galvanizing kunoita basa rakakosha mukugadzira zvigadzirwa zvesimbi.ASTM A153 uye ASTM A123 ndiwo maviri anowanzo shandiswa zviyero zvinoshandiswa kutungamira zvakatemwa uye zvinodiwa kune inopisa-dip galvanizing process.Kunyangwe iwo ese anotarisa pakupa corrosion resistance dziviriro, pane misiyano yeruzivo nemashandisirwo.
Zvakafanana:
Kupisa dip galvanizing process: Ose ASTM A153 uye ASTM A123 anosanganisira kunyudza zvigadzirwa zvesimbi muzinc yakanyungudutswa kuti igadzire zinc yekuputira uye inopa kudzivirirwa kwekudzivirira.
Corrosion resistance: Mayero ese ari maviri akazvipira kupa corrosion kuramba, kuwedzera hupenyu hwezvigadzirwa zvesimbi, nekudzivirira kubva kune ekunze kwezvakatipoteredza.
Misiyano:
1.Application scope:
ASTM A153 inowanzoshanda kune zvigadzirwa zvesimbi, senge corroded angle simbi, pombi dzesimbi, nezvimwewo;ASTM A123 inonyanya kushanda kune zvigadzirwa zvesimbi nesimbi, zvinosanganisira forgings, castings, uye mamwe marudzi chaiwo ezvigadzirwa zvesimbi.
2.Coating ukobvu zvinodiwa:
ASTM A153 uye ASTM A123 vane zvakasiyana ukobvu zvinodiwa kuti galvanized coatings.Kazhinji kutaura, A123 inoda yakakora zinc coating kuti ipe dhigirii repamusoro rekudzivirira ngura.
3.Measurement nzira uye kuyedzwa zviyero:
Kune zvakare mimwe misiyano pakati peASTM A153 neASTM A123 maererano nenzira dzekuyedza uye zviyero.Iyi miedzo inowanzo sanganisira kutaridzika, kunamatira, uye kukora kwehuputi hwejasi.
3.Kunzwisisa misiyano pakati pezviyero izvi kwakakosha kune vanogadzira nevatengi.Kusarudzwa kwakaringana kwemazinga akakodzera kunogona kuve nechokwadi chekudzivirira kwecorrosion yezvigadzirwa zvesimbi, kuwedzera hupenyu hwavo hwesevhisi, uye kuderedza mari yekugadzirisa.
Kunyangwe ese ari maviri ASTM A153 uye ASTM A123 achivavarira kupa zviyero zvekupisa-dip galvanizing, kunzwisisa hunhu hwavo hwakasiyana uye huwandu hwekushandisa kunogona kubatsira nyanzvi dzeindasitiri kusarudza mazinga akakodzera nehungwaru, kuve nechokwadi chinodiwa anti-corrosion kuita uye mhando.
Kunzwisisa mazinga maviri aya kunogona kubatsira indasitiri kuti inzwisise zvirinani mashandisiro ayo mukurwisa-corrosion kurapwa kwezvigadzirwa zvesimbi uye kusimudzira kusimukira kweindasitiri yezvigadzirwa zvesimbi kune gwara rinoshanda uye rakasimba.
Izvo zviri pamusoro ndezvimwe zvikuru zvakafanana uye mutsauko pakati peASTM A153 uye ASTM A123 zviyero.Tinovimba izvi zvinogona kukubatsira kuti unzwisise zviri nani hunhu hweaya maviri anopisa-dip galvanized zviyero.
Zviri pamusoro apa ndezvekutarisa chete, ndapota nyatso tevera zviyero zvinoenderana mune chaiwo maapplication.
Ichi chinyorwa chine chinangwa chekuzivisa muchidimbu kufanana uye mutsauko pakati peASTM A153 neASTM A123 hot-dip galvanizing standards, kuitira kubatsira vaverengi kunzwisisa zviri nani maitiro avo uye kushanda.
