Float Glass uye Rolled Glass
Float Glass
Iyo nzira yekuyangarara, yakagadzirwa naSir Alastair Pilkington muna 1952, inogadzira girazi rakatsetseka.Iyi nzira inobvumira kugadzirwa kwegirazi rakajeka, rakatsvuka uye rakavharwa pazvivakwa, uye magirazi akajeka uye ane tinted emotokari.
Kune akatenderedza 260 zvidyarwa zvinoyangarara pasi rose zvine zvakabatanidzwa zvinobuda zvinosvika mazana masere ezviuru ematani egirazi pasvondo.Chirimwa chinoyangarara, chinoshanda chisingaperi kwemakore ari pakati pe11-15, chinoita makiromita angangoita 6000 egirazi pagore muhukobvu hwe0.4mm kusvika 25mm uye muhupamhi hunosvika 3 metres.
Mutsetse wekuyangarara unogona kureba ingangoita hafu yekiromita.Zvigadzirwa zvinopinda kune rumwe rutivi uye kubva kune mamwe mahwendefa egirazi anobuda, akachekwa chaizvo kusvika kune yakatarwa, pamitengo inokwira se6,000 matani pasvondo.Pakati nhema nhanhatu dzakabatanidzwa zvikuru.
Kunyunguduka uye kunatsa
Zvigadzirwa zvakanaka-zviyo, zvakanyatsodzorwa zvehutano, zvinosanganiswa kuita batch, iyo inoyerera muchoto chinopisa kusvika ku1500 ° C.
Float nhasi inogadzira girazi repedyo optical quality.Maitiro akati wandei - kunyunguduka, kunatsa, homogenising - kunoitika panguva imwe chete mu2,000 matani egirazi rakanyungudutswa muchoto.Zvinoitika munzvimbo dzakaparadzana mune yakaoma girazi inoyerera inotungamirwa nekupisa kwakanyanya, sezvinoratidzwa nedhiyagiramu.Inowedzera kuenderera mberi kwekunyunguduka, kunogara kwenguva yakareba semaawa makumi mashanu, iyo inopa girazi pa 1,100 ° C, isina kubva kune inclusions uye mabhubhu, zvakanaka uye inoramba ichienda kubhati rekuyangarara.Iyo yekunyunguduka ndiyo kiyi yemhando yegirazi;uye zvinyorwa zvinogona kuchinjwa kuti zvishandure zvimiro zvechigadzirwa chakapedzwa.
Float Bath
Girazi rinobva mukunyunguduka rinoyerera zvinyoro pamusoro pechipopoti chinoramba chichienda pachionioni-chakaita serata rakanyungudutswa, richitanga pa1,100°C uye richisiya bhavhu rinoyangarara seribhoni rakasimba pa600°C.
Nheyo yegirazi inoyangarara haina kuchinjika kubva kuma1950 asi chigadzirwa chakachinja zvakanyanya: kubva kune imwechete yakaenzana ukobvu hwe6.8mm kusvika kune imwe kubva pasi-millimita kusvika 25mm;kubva paribhoni rinowanzo shatiswa ne inclusions, mabubbles uye striations kusvika kunenge optical perfection.Float inoburitsa izvo zvinozivikanwa sekupedzisa moto, kupenya kwezvitsva zvechinaware.
Annealing & Kuongorora & Kucheka kuodha
● Anealing
Zvisinei nerunyararo rwunogadzirwa girazi rinoyangarara, kushushikana kukuru kunogadzirwa muRibhoni painotonhora.Kunyanya kunetseka uye girazi richaputsika pasi pemucheki.Mufananidzo unoratidza kushushikana kuburikidza neribhoni, inoratidzwa nechiedza chepolarized.Kuti ubvise kushushikana uku ribhoni inorapwa kupisa muchoto chakareba chinonzi lehr.Tembiricha dzinonyatsodzorwa zvese pamwe nekuyambuka ribhoni.
●Inspection
Iyo nzira yekuyangarara inozivikanwa nekugadzira girazi rakati sandara, risina kukanganisa.Asi kuti uve nechokwadi chemhando yepamusoro, kuongorora kunoitika padanho rega rega.Dzimwe nguva bubble harina kubviswa panguva yekunatswa, tsanga yejecha inoramba kunyunguduka, kudengenyeka mutin kunoisa ripples mugirazi ribhoni.Automated on-line inspection inoita zvinhu zviviri.Inoratidza kukanganisa kwemaitiro kumusoro uko kunogona kugadziriswa kugonesa makomputa kudzika pasi kuti atungamirire vanocheka kutenderera kukanganisa.Tekinoroji yekuongorora ikozvino inobvumira zviyero zvinopfuura miriyoni zana sekondi kuti zviitwe paribhoni, kutsvaga zvikanganiso izvo ziso rega risingakwanise kuona.
Iyo data inotyaira 'vakangwara' vanocheka, vachiwedzera kunatsiridza mhando yechigadzirwa kumutengi.
●Kucheka kurongeka
Mavhiri edhaimani anocheka selvedge - yakasimbiswa mipendero - uye cheka ribhoni kusvika saizi inorairwa nekombuta.Girazi rinoyangarara rinotengeswa neskweya mita.Makomputa anoshandura zvinodiwa nevatengi kuita mapatani ekucheka akagadzirirwa kuderedza kutambisa.
Yakakungurutswa Girazi
Iyo rolling process inoshandiswa kugadzira solar panel girazi, patterned flat glass uye wired glass.Rukova runopfuurira rwegirazi yakanyungudutswa inodururwa pakati pemvura-yakatonhorera rollers.
Girazi rakatenderedzwa riri kuwedzera kushandiswa muPV modules uye vateresi vanopisa nekuda kweiyo yepamusoro transmittance.Pane musiyano mudiki wemutengo pakati pegirazi rakakungurutswa uye rinoyangarara.
Girazi rakakungurutswa rakakosha nekuda kweiyo macroscopic chimiro.Iyo yakakwira iyo transmittance iri nani uye nhasi yakakwira kuita yakaderera simbi yakakungurutswa girazi ichasvika kazhinji 91% transmittance.
Izvo zvakare zvinokwanisika kuunza chimiro chepamusoro pamusoro pegirazi.Zvimiro zvakasiyana-siyana zvepamusoro zvinosarudzwa zvichienderana nezvinodiwa.
Yakaputirwa pamusoro pechimiro chinowanzo shandiswa kuwedzera simba rekunamatira pakati peEVA negirazi muPV application.Girazi rakagadzirwa rinoshandiswa mune ese PV uye thermo solar application.
Girazi rine muenzaniso rinogadzirwa nenzira imwechete yekupfuura umo girazi rinoyerera richienda kumarora patembiricha ingangoita 1050°C.Iyo yepasi yakakandwa simbi kana simbi isina simbi roller yakanyorwa neiyo yakaipa yemuenzaniso;roller yepamusoro yakatsetseka.Ukobvu hunodzorwa nekugadzirisa gap pakati pema rollers.Ribhoni inosiya ma rollers pa 850°C uye inotsigirwa pamusoro pemvura yakatonhodzwa ma rollers kusvika kune annealing lehr.Mushure mokunge annealing girazi rinochekwa kusvika pakukura.
Wired girazi inogadzirwa mune kaviri pass process.Maitiro acho anoshandisa maviri akazvimirira maviri emvura akatonhodzwa achigadzira rollers imwe neimwe inodyiswa neyakasiyana kuyerera kwegirazi rakanyungudutswa kubva muchoto chinonyunguduka chakajairika.Yekutanga ma rollers anoburitsa ribhoni inoenderera yegirazi, hafu yehupamhi hwechigadzirwa chekupedzisira.Izvi zvakafukidzwa newaya mesh.Chechipiri chekudya chegirazi, kupa ribhoni hupamhi hwakafanana nehwekutanga, inobva yawedzerwa uye, newaya mesh "sandwiched", ribhoni inopfuura nepakati pechipiri chemakumbo anoumba ribhoni yekupedzisira yegirazi rine waya.Mushure mekuvhara, ribhoni inochekwa nekucheka kwakakosha uye kuronga kwekucheka.
