Izici ezithinta ukushuba kwe-zinc steel grating coating ngokuyinhloko: ukwakheka kwensimbi ye-grating yensimbi, ukuhwaqana kwendawo yensimbi, okuqukethwe kanye nokusatshalaliswa kwezinto ezisebenzayo i-silicon ne-phosphorus ku-grating yensimbi, ukucindezeleka kwangaphakathi kwe-grating yensimbi, ubukhulu bejiyomethri bocezu lokusebenzela lwe-steel, kanye nenqubo ye-hot-dip galvanizing yensimbi. Izindinganiso zamanje zamazwe ngamazwe kanye ne-Chinese hot-dip galvanizing zihlukaniswa zibe izigaba ngokuvumelana nobukhulu bepuleti. Ugqinsi olumaphakathi kanye nogqinsi lwasendaweni lwe-zinc enamathelayo kufanele lufinyelele ugqinsi oluhambisanayo ukuze kunqunywe ukusebenza kokunqanda ukugqwala kwe-zinc. Isikhathi esidingekayo ukuze kuzuzwe ukulingana okushisayo kanye ne-zinc-iron exchange equilibrium for steel grating workpieces enogqinsi oluhlukene sihlukile, futhi ukujiya kokunamathela okwakhiwa nakho kuhlukile. Ugqinsi oluyisilinganiso sokumboza ezingeni liyivelu yokuhlangenwe nakho kokukhiqizwa kwemboni esekelwe endleleni eshiwo ngenhla yokufaka uthayela, futhi ukushuba kwendawo kuyinani lokuhlangenwe nakho elidingekayo ukuze kucatshangelwe ukusatshalaliswa okungalingani kogqinsi lwezinki kanye nezidingo zokumelana nokugqwala kwento enamathelayo. Ngakho-ke, izinga le-ISO, izinga le-ASTM laseMelika, izinga le-JS laseJapane kanye nezinga laseShayina kunezidingo ezihluke kancane zobukhulu be-zinc coating, ezifanayo. Ngokwezinhlinzeko ze-hot-dip galvanizing standard GB B 13912-2002 ye-People's Republic of China. Izindinganiso zokumboza i-zinc zemikhiqizo yegriza yensimbi eshisayo ediphu imi kanje: Kumagridi ensimbi ediphu ashisayo anogqinsi olungaphezu noma olulingana no-6mm, ukujiya kwe-zinc okumaphakathi kugridi yensimbi eshisayo ediphu kufanele kube kukhulu kunama-microns angu-85, futhi ukujiya kwendawo kufanele kube kukhulu kuno-70 microns. Kumagridi ensimbi ediphu ashisayo anogqinsi olungaphansi kuka-6mm nangaphezulu kuka-3mm, ukujiya kwe-zinc okumaphakathi endaweni eshisayo ye-galvanized steel grating kufanele kube kukhulu kunama-microns angu-70, futhi ukujiya kwendawo kufanele kube kukhulu kuno-55 microns. Ezingxenyeni ezishisayo zensimbi ezicwebezelayo ezinogqinsi olungaphansi kuka-3mm nangaphezulu kuka-1.5mm, ukujiya kwe-zinc okumaphakathi endaweni eshisayo yegridi yensimbi kufanele kube kukhulu kunama-microns angu-55, futhi ukujiya kwendawo kufanele kube kukhulu kuno-45 microns.
Iqhaza kanye nomthelela wokuqina kwe-hot-dip galvanizing coating
Ugqinsi lwe-hot-dip galvanized coating ku-grating yensimbi inquma ukusebenza kokunqanda ukugqwala kwe-grating yensimbi. Abasebenzisi bangakhetha ukujiya kwe-zinc enamathelayo ephakeme noma ephansi kunokuvamile. Kunzima ukuthola i-coating eqinile ekukhiqizeni izimboni ze-gratings yensimbi encane enendawo ebushelelezi engaphansi kuka-3mm. Ukwengeza, ugqinsi lwe-zinc enamathelayo olungalingani nobukhulu bepuleti lokugaya lwensimbi luzothinta amandla okubopha phakathi kwento enamathelayo kanye ne-substrate kanye nekhwalithi yokubukeka kwentolo. Ifu eliwugqinsi kakhulu le-plating lizokwenza ukuthi ukunamathela kubonakale kumaholoholo futhi kulula ukuxebuka. I-steel plated grating ayikwazi ukumelana nokushayisana ngesikhathi sokuthutha nokufakwa. Uma kunezinto ezisebenzayo kakhulu ze-silicon ne-phosphorus ezintweni zokusetshenziswa ze-grating yensimbi, kunzima kakhulu ukuthola i-coating encane ekukhiqizeni izimboni. Lokhu kungenxa yokuthi okuqukethwe kwe-silicon ensimbi kuthinta imodi yokukhula kongqimba lwengxubevange phakathi kwe-zinc nensimbi, okuzokwenza ukuthi (, isigaba se-zinc-iron alloy layer sikhule ngokushesha futhi (phezulu kwe-coating, okuholela endaweni enamathelayo eqinile futhi efiphele, yakhe i-grey enamathelayo enamathelayo. Ngakho-ke, njengoba kuxoxiwe ngenhla, kukhona ukungaqiniseki kokukhula kwensimbi eqinile. thola uhla oluthile logqinsi olunamathelayo ekukhiqizweni kwangempela Ugqinsi olucaciswe kuzinga lokuphehla insimbi elishisayo liyinani elibonakalayo elikhiqizwa ngemva kwenani elikhulu lokuhlola, kucatshangelwa izici ezihlukahlukene nezimfuneko, futhi kunengqondo kakhudlwana.
