Chidzidzo Chakadzama Pamusoro Pehukama Huripo Pakati Pekuumbwa Uye Kushanda kweGalvalume Steel Coil

Munzvimbo dzakadai sekuvaka madziro emaketeni, dzimba dzemidziyo, uye mabhureki emagetsi, macoil esimbi egalvalume ari kutsiva zvishoma nezvishoma macoil esimbi ekare egalvalume sesarudzo huru nekuda kwezvakanaka zvawo zviviri zvekudzivirira ngura uye kushanda zvakanaka kwemari. Ingave iri Galvalume Steel Coil Price, chinhu chikuru chaunofanira kufunga nezvacho mukutenga mainjiniya, kana kutiASTM A792 GalvalumeZvichitsanangurwa zvakajeka mumatanho ekugadzira, musiyano wekushanda kwepakati unobva mukudzora kwakarurama kwekuumbwa. Nhasi, tichatanga nekuongorora kwekuumbwa kuti tiwane zvakavanzika zvekushanda kwesimbi dzegalvalume (kusanganisira Galvalume Roll, Steel Coil Galvalume, nezvimwewo).
I. Kuongororwa kweCore Composition yeGalvalume Steel Coil
Kushanda kwesimbi dzegalvalume kunoonekwa ne "base material" uye "coating". Zvikamu zvakasiyana zvinokanganisa zvakananga mamiriro ezvinhu anoshandiswa pakugadzirwa kwekupedzisira. Semuenzaniso, dhizaini yeGalvalume Steel Coil Az150, iyo inoda kuramba ngura zvakanyanya, yakasiyana zvakanyanya neyeGalvalume Coil yakajairika.
1. Kuumbwa kweCoating: "Goridhe Ratio" yeAluminium, Zinc, neSilicon

Kuputira kwealuminium-zinc hakusi simbi imwe chete, asi sisitimu ye alloy yealuminium (55%), zinc (43.5%), uye silicon (1.5%). Chiyero ichi ndicho mhinduro yakanakisisa inosimbiswa kuburikidza nekushandisa kwenguva refu:
* Aluminium (Al): "Chinodzivisa ngura" chejira. Aluminium inoumba firimu reAl₂O₃ oxide rakakora pamusoro pesimbi, iro rinogona kudzivirira ngura kubva munzvimbo dzakaoma dzakadai semvura inonaya nemunyu. Ichi ndicho chikonzero chikuru nei simbi dzakaputirwa nealuminium-zinc dzichidzivirira ngura zvakapetwa katatu kusvika kashanu kupfuura simbi dzakajairwa dzakaputirwa;
* Zinc (Zn): Inoshanda se "kuchengetedza anode yechibayiro." Kana chifukidziro chakwenywa, zinc inonyatsoita pamwe chete neokisijeni kudzivirira simbi yesimbi kuti isaite ngura. Panguva imwe chete, kuvapo kwezinc kunogonawo kuwedzera kugona kwechifukidziro, zvichiita kuti zvive nyore kuti Galvalume Roll ikotame uye isimbiswe;
* Silicon (Si): Inogadzirisa dambudziko re "kunamatira kwekuputira". Silicon inogona kudzivirira kusangana pakati pearuminiyamu nesimbi kuti igadzire maFe-Al intermetallic compounds akaomarara uye akaomarara, zvichideredza njodzi yekuputira kwekuputira. Kugadzikana kwesilicon kwakakosha zvikuru kune Galvalume Steel Coil Az150 yakakora (AZ150 inomiririra 150g yehuremu hwekuputira pa square mita).
2. Kuumbwa kweSubstrate: "Chivimbiso Chekutanga" cheSimbi Isina Kabhoni Yakawanda

Chikamu chegalvalume simbi coilsKazhinji kacho simbi ine kabhoni shoma (kabhoni yakawanda ≤0.12%), inowedzerwa ne manganese mashoma (0.3-0.6%) uye phosphorus (≤0.045%): Kabhoni (C): Kabhoni yakawanda ichaita kuti substrate iome zvakanyanya, zvichiita kuti ive nyore kutsemuka panguva yekugadzirisa; kuderera kwehuwandu kunoderedza simba re coil yesimbi. Nokudaro, kabhoni yesimbi ine kabhoni shoma inofanira kudzorwa zvakasimba mukati me "simba uye processability balance range"; Manganese (Mn): Kabhoni shoma inogona kuvandudza simba rekugadzira substrate pasina kukanganisa zvakanyanya ductility, zvichiita kuti ive yakakodzera kushandiswa kwekutakura mutoro (senge galvalume yesimbi yesimbi ye photovoltaic brackets); Phosphorus (P): Phosphorus inowedzera kuputsika kwesimbi, saka phosphorus iri mu substrate inofanira kunge yakaganhurirwa, inova imwe yezviratidzo zvakatsanangurwa zvakajeka muASTM A792 Galvalume standard.
II. Hukama Huripo Pakati Pekuumbwa Kwezvinhu Nehunhu Hunokosha Hwekuita Kunzwisisa kuumbwa kwezvinhu kunotibvumira kuona zvakajeka kuti sei vamweMakoiri eGalvalumedzakakodzera kugadzirwa panze nepo dzimwe dzakakodzera kuiswa kwemidziyo yemagetsi—chinhu chikuru chiri mukusiyana kwekushanda kunobva mukugadziriswa kwezvimiro.

1. Kuramba Kuora: Zviri MuAruminiyamu Zvinosarudza "Nhanho Yekudzivirira" Kuramba Kuora ndiko kukwikwidzana kukuru kwemipumburu yegalvalume, uye hukama hwayo nekuumbwa kwayo hwakanyatsojeka: Kana huwandu hwealuminium mujira hukawedzera kubva pa50% kusvika pa55%, huwandu hweAl₂O₃ oxide film hunovandudzika zvakanyanya. Munzvimbo dzekupfapfaidza munyu pamhenderekedzo yegungwa, nguva yekuora kwesimbi inogona kuwedzerwa kubva pamakore gumi kusvika pamakore anopfuura makumi maviri. Kana huwandu hwesilicon huri pasi pe1%, zvichaita kuti pave nekunamatira pakati pejira nesubstrate, zvichiita kuti jasi rive nyore kuputira mukuyedzwa kwesalt spray; kana riri pamusoro pe2%, rinowedzera kuputsika kwejasi, nokudaro richideredza kugara kwenguva refu kwekudzivirira ngura. Ichi ndicho chikonzero nei Galvalume Steel Coil AZ150 iine simba rekudzivirira ngura kupfuura AZ100 (100g coating pa square meter) - harisi iro gobvu chete, asi chiyero chealuminium-zinc-silicon chakakodzerawo zviri nani kune zvinodiwa zvekudzivirira zvakanyanya.
2. Hunhu hweMechanical: Substrate Composition Inotonga "Simba uye Kugona Kugadziriswa"
Simba: Pakuwedzera kwe0.1% kwehuwandu hwemanganese hwe substrate, simba remuko wesimbi rinogona kuwedzera ne5-8 MPa. Saka, kune Galvalume Steel Coil inoshandiswa mukutakura mutoro, huwandu hwemanganese hunodzorwa pa0.5-0.6%.
Kugona Kugadziriswa: Pamashandisirwo anoda kudhindwa kwakaomarara, senge macasing emidziyo, substrates dzine kabhoni ≤0.1% dzinosarudzwa, nepo silicon iri mudhindwa ichideredzwa kusvika pa1.5% kudzivirira kudhindwa kwedhindwa panguva yekudhindwa. 3. Kuramba Kupisa Kwakanyanya: Kubatsira kweAluminium kwe "Kugadzikana Kwakanyanya Kwekupisa"
Nzvimbo yekunyunguduka kwearuminiyamu (660℃) yakakwira zvikuru kupfuura yezinc (419℃), saka, kuramba kupisa kwakanyanya kwealuminized zinc steel coils kwakanyanya kupfuura kweagalvanized steel coils:
Munzvimbo dziri pasi pe200℃ (senge machira eovheni), mashandiro ekuputira akagadzikana;
Kunyangwe kana tembiricha yakakwira kwenguva pfupi ye300℃, firimu reAl₂O₃ rinogona kudzivirira oxidation yependi, ndicho chikonzero chikuru chinoita kuti Galvalume Roll ikwanise kushandiswa pakuisa chimneys uye pakuisa mapaipi ekupisa kwakanyanya.

III. Hukama Huripo Pakati Pekuumbwa, Kushanda, uye Mutengo weGalvalume Steel Coil

Vanhu vazhinji vanoshamisika panguva yekutenga: Sei musiyano wemutengo weGalvalume Coil ine zvirevo zvakafanana uchigona kusvika 100-200 RMB/tani? Muchidimbu, musiyano wemutengo unoratidza mutengo wezvikamu: Mutengo wekuputira: Mutengo wemusika wearuminiyamu wakapetwa kaviri kana katatu pane zinc. Saka, kana aruminiyamu iri mupurasitiki yakakwira (semuenzaniso, AZ150 zvichienzaniswa neAZ90), mutengo wakakwira, uye mutengo weGalvalume Steel Coil wakakwira. Mutengo wezvinhu zvekutanga: Kana manganese iri pamusoro uye phosphorus iri pasi musimbi ine kabhoni shoma, mutengo wekunyungudutsa wakakwira, uye mutengo weGalvalume Steel Coil wakakwira. Mutengo wenguva dzose: Zvigadzirwa zvinoenderana neASTM A792 Galvalume standard zvine kudzora kwakasimba kwezvikamu (semuenzaniso, kutsauka kwealuminium ≤ ±1%), mwero wezvimedu wakakwira panguva yekugadzira, uye mutengo wakakwira ne5-8% kupfuura zvigadzirwa zvisiri zvenguva dzose. IV. Nyaya Yekushandisa Inoshanda: Kukosha Kwekusarudza Kuumbwa

Chirongwa chekuvaka gungwa chakaenzanisa mhando mbiri dzesimbi dzegalvalume: Ordinary Galvalume Coil (50% aruminiyamu, 1% silicon): Kuora kwakaonekwa munzvimbo iyoyo mushure memakore matatu ekushandiswa; Galvalume Steel Coil Az150 (55% aruminiyamu, 1.5% silicon), zvichienderana neASTM A792: Hapana ngura yakakura mushure memakore mashanu ekushandiswa, uye hapana kuchinja panguva yekukanganiswa kwedutu (hunhu hwepamusoro hwemakanika). Chirongwa ichi chakasarudza chechipiri. Kunyangwe mutengo wekutanga weGalvalume Steel Coil waive wakakwira ne150 RMB/ton, hupenyu hwebasa hwakawedzerwa nemakore anopfuura gumi, zvichikonzera mutengo wakaderera wenguva refu.

Mhedziso: Kuumbwa kwema coil esimbi egalvalume inzira "yekuenderana chaizvo nezvinodiwa": AZ150 (aluminium yakakwira, silicon yakakwira) inosarudzwa kuti irambe yakasimba mukuora; silicon yakaderera, substrates dzisina kabhoni yakawanda dzinosarudzwa kuti dzishandiswe zvakanyanya; uye zvigadzirwa zveASTM A792 zvakajairwa zvinosarudzwa kuti zvishandiswe kunze kwenyika. Nekuvandudzwa kweramangwana kwemaindasitiri emagetsi ezuva nezuva uye matsva, kugadzirisa kugadzirwa (sekuwedzera huwandu hwezvinhu zvisingawanzoitiki zvepasi kuti zvivandudze kuramba kwekuora) kuchava nzira yakakosha yekuvandudza ma coil esimbi e aluminized zinc, zvichiwedzera kuwedzera miganhu yekushandisa kwawo.
