Girazi rinoita basa rakakosha mumaindasitiri akasiyana siyana nekuda kwekusiyana-siyana kwaro. Kunze kwezvinowanzoshandiswacosmetic packaging containers, zvinosanganisira mhando dzinoshandiswa kugadzira magonhi nemahwindo, segirazi risina buri, girazi rakashongedzwa, neaya anoshandiswa mukushongedzerwa kwehunyanzvi, segirazi rakasanganiswa uye girazi rakanamirwa.
Hunhu hweSandblasting
Sandblasting inzira iyo mweya wakadzvanywa unofambisa mabrasives pamusoro pepamusoro kuti urapwe. Iyo inozivikanwa zvakare sekupfurwa kwepfuti kana kupfurwa peening. Pakutanga, jecha ndiro roga raishandiswa, saka nzira iyi yaiwanzonzi jecha. Sandblasting inowana mhedzisiro mbiri: inochenesa pasi kusvika padanho rinodiwa uye inogadzira imwe roughness kuti iwedzere kunamira kwekunamatira pane substrate. Kunyangwe iyo yakanakisa mabhanhire inonetsekana kuti ibatike zvakanaka kune isina kurapwa pamusoro penguva refu.
Surface pretreatment inosanganisira kuchenesa uye kugadzira roughness inodiwa ye "kuvhara" yekuvharisa. Maindasitiri ekupfekedza akaiswa panzvimbo yakabatwa nejecha kuputika anogona kuwedzera hupenyu hwekuvhara nekanopfuura ka3.5 zvichienzaniswa nedzimwe nzira. Imwe mukana we sandblasting ndeyekuti kushata kwepamusoro kunogona kufanotemerwa uye kuwanikwa nyore panguva yekuchenesa.
AboutFrosted Glass
Frosting inosanganisira kuita kuti pamusoro pechinhu chakatanga kutsvedzerera kuve kwakakwasharara, zvichiita kuti chiedza chigadzire ratidziro yakapararira pamusoro. Mukutaura kwemakemikari, girazi rinokwenenzverwa kana kukwenenzverwa nemaoko nemaabrasives senge corundum, silica sand, kana garnet poda kugadzira nzvimbo yakafanana yakaoma. Neimwe nzira, hydrofluoric acid mhinduro inogona kushandiswa kugadzira girazi uye zvimwe zvinhu, zvichikonzera girazi rechando. Mukuchengetedza ganda, kuputika kunobvisa masero eganda akafa, ayo anoshanda asi haafaniri kushandiswa zvakanyanya, zvichienderana neganda rako. Kunyanya kuburitsa kunogona kuuraya maseru achangobva kugadzirwa asati agadzira membrane yekuzvidzivirira, zvichiita kuti ganda rakapfava rive nyore kutyisidzira kunze senge UV mwaranzi.
Kusiyana pakati peFrosted neSandblasted Glass
Zvese chando uye sandblasting maitiro ekugadzira nzvimbo yegirazi kupenya, zvichiita kuti mwenje upararire zvakaenzana kuburikidza nemarambi, uye vashandisi vese vanoona zvichinetsa kusiyanisa pakati pemaitiro maviri aya. Heano maitiro chaiwo ekugadzira ese ari maviri maitiro uye maitiro ekuaziva.
Frosting Process
Girazi rechando rinonyudzwa mumushonga wakagadzirwa ane acidic (kana wakaputirwa neacidic paste) kupinza girazi pamusoro kuburikidza nekukukurwa kweasidhi yakasimba. Panguva imwe chete, hydrofluoric ammonia mune yakasimba asidhi mhinduro inonamira girazi pamusoro. Naizvozvo, chando chakaitwa zvakanaka chinoparira girazi rakatsetseka rakatsetseka rine crystalline kupararira uye hazy maitiro. Kana pasi pakaita kushata, zvinoratidza kukukurwa kweasidhi pagirazi, zvichiratidza kusakura kwemhizha. Zvimwe zvikamu zvinogona kunge zvichiri kushaya makristasi (anowanzozivikanwa se "hapana sanding" kana "magirazi mavara"), zvichiratidzawo kusashanda zvakanaka. Iyi tekinoroji inonetsa uye inoratidzwa nekutaridzika kweinopenya makristasi pamusoro pegirazi, ayo anoumba pasi pemamiriro akaomarara nekuda kwekusvika kwekushandiswa kwehydrofluoric ammonia.
Sandblasting Process
Kuita uku kunowanzoitika, apo jecha rinopfura tsanga dzejecha nekumhanya kukuru pamusoro pegirazi, richigadzira nzvimbo yakanaka isina kuenzana inoparadzira chiedza kugadzira kupenya kwakapararira kana chiedza chapfuura. Zvigadzirwa zvegirazi zvinogadziriswa nejecha zvine chimiro chakaomarara pamusoro. Nekuda kwekuti girazi repamusoro rakakuvadzwa, girazi rekutanga rinoonekera rinoratidzika chena kana raiswa muchiedza. Iyo nzira yekuomerwa nhanho ivhareji.
Aya maitiro maviri akasiyana zvachose. Girazi rechando rinowanzo kudhura kupfuura girazi rakaputika, uye mhedzisiro yacho inonyanya kuenderana nezvinodiwa nemushandisi. Mamwe marudzi akasiyana egirazi haana kukodzera kutonhora. Kubva pamaonero ekutsvaga hukuru, girazi rechando rinofanira kusarudzwa. Sandblasting matekiniki anowanzo kuwanikwa nemafekitori mazhinji, asi kuwana yakanakisa girazi rechando hakusi nyore.
