Iav ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam vim nws qhov kev hloov pauv tau yooj yim. Sib nrug ntawm kev siv feem ntaucov thawv ntim khoom kom zoo nkauj, nws suav nrog cov hom siv rau kev ua qhov rooj thiab qhov rai, xws li iav hollow, iav laminated, thiab cov uas siv rau hauv kev kho kom zoo nkauj kos duab, xws li iav fused thiab iav embossed.
Cov yam ntxwv ntawm Sandblasting
Kev siv xuab zeb tua yog ib txoj kev uas cua compressed thawb cov abrasives mus rau ntawm ib qho chaw rau kev kho. Nws tseem hu ua shot blasting lossis shot peening. Chiv thawj, xuab zeb yog tib yam abrasive siv, yog li cov txheej txheem no feem ntau hu ua sandblasting. Sandblasting ua tiav ob qho txiaj ntsig: nws ntxuav qhov chaw mus rau qib uas xav tau thiab tsim qee qhov roughness los txhim kho cov txheej lo rau ntawm lub substrate. Txawm tias cov txheej zoo tshaj plaws kuj nyuaj rau lo rau cov chaw tsis kho kom zoo rau lub sijhawm ntev.
Kev kho ua ntej ntawm qhov chaw suav nrog kev ntxuav thiab tsim kom muaj qhov roughness uas xav tau rau "xauv" lub txheej. Cov txheej txheem kev lag luam siv rau cov chaw kho nrog sandblasting tuaj yeem ua rau lub neej ntawm lub txheej ntev dua 3.5 npaug piv rau lwm txoj hauv kev. Lwm qhov zoo ntawm sandblasting yog tias qhov roughness ntawm qhov chaw tuaj yeem txiav txim siab ua ntej thiab yooj yim ua tiav thaum lub sijhawm ntxuav.
TxogIav khov
Kev ua kom cov khoom du yog ua kom qhov chaw ntawm ib yam khoom uas thaum ub du thiab ntxhib, ua rau lub teeb ci ntsa iab rau ntawm qhov chaw. Hauv cov tshuaj lom neeg, iav raug txhuam los ntawm tshuab lossis txhuam tes nrog cov khoom siv txhuam xws li corundum, xuab zeb silica, lossis hmoov garnet los tsim ib qho chaw ntxhib sib npaug. Xwb, cov kua hydrofluoric acid tuaj yeem siv los ua cov iav thiab lwm yam khoom, ua rau iav khov. Hauv kev saib xyuas tawv nqaij, kev tshem tawm cov hlwb tuag ntawm daim tawv nqaij, uas zoo tab sis yuav tsum tsis txhob siv ntau dhau, nyob ntawm koj hom tawv nqaij. Kev tshem tawm ntau dhau tuaj yeem tua cov hlwb tshiab ua ntej ua ntej tsim cov membrane tiv thaiv tus kheej, ua rau daim tawv nqaij mos mos raug kev hem thawj sab nraud xws li UV rays.
Qhov Sib Txawv Ntawm Frosted Thiab Sandblasted Iav
Ob qho tib si frosting thiab sandblasting yog cov txheej txheem rau kev ua kom cov iav nto translucent, tso cai rau lub teeb kom sib npaug thoob plaws hauv cov teeb pom kev zoo, thiab cov neeg siv dav dav pom tias nws nyuaj rau qhov sib txawv ntawm ob qho txheej txheem no. Nov yog cov txheej txheem tsim khoom tshwj xeeb rau ob qho txheej txheem thiab yuav ua li cas txheeb xyuas lawv.
Txheej Txheem Frosting
Cov iav khov kho raug muab tso rau hauv cov kua qaub uas tau npaj tseg (lossis coated nrog acidic paste) los txiav cov iav nto los ntawm kev puas tsuaj ntawm cov kua qaub muaj zog. Tib lub sijhawm, hydrofluoric ammonia hauv cov kua qaub muaj zog ua rau cov iav nto. Yog li ntawd, cov frosting ua tiav zoo ua rau cov iav nto du heev nrog cov crystalline scattering thiab cov teebmeem hazy. Yog tias qhov chaw yog qhov ntxhib, nws qhia txog kev puas tsuaj ntawm cov kua qaub ntawm cov iav, qhia txog tus kws ua tes tsis muaj kev loj hlob. Qee qhov chaw tseem yuav tsis muaj cov siv lead ua (feem ntau hu ua "tsis muaj sanding" lossis "cov iav pob"), kuj qhia txog kev ua haujlwm tsis zoo. Cov txheej txheem no yog qhov nyuaj rau kev siv tshuab thiab yog tus cwj pwm los ntawm cov tsos ntawm cov siv lead ua ci ntsa iab ntawm cov iav nto, uas tsim nyob rau hauv cov xwm txheej tseem ceeb vim yog kev siv hydrofluoric ammonia sai sai.
Cov Txheej Txheem Sandblasting
Cov txheej txheem no yog ib qho uas siv ntau heev, qhov twg lub tshuab xuab zeb tua cov xuab zeb ntawm qhov ceev ceev rau ntawm qhov chaw iav, tsim kom muaj qhov chaw tsis sib luag uas ua rau lub teeb ci ntsa iab thaum lub teeb hla dhau. Cov khoom iav uas ua los ntawm kev xuab zeb muaj cov qauv ntxhib ntawm qhov chaw. Vim tias qhov chaw iav puas lawm, lub iav pob tshab thaum xub thawj zoo li dawb thaum raug lub teeb. Qib nyuaj ntawm cov txheej txheem yog qhov nruab nrab.
Ob txoj kev no txawv kiag li. Cov iav frosted feem ntau kim dua li cov iav sandblasted, thiab qhov cuam tshuam feem ntau nyob ntawm tus neeg siv nyiam. Qee hom iav tshwj xeeb tsis haum rau frosting. Los ntawm qhov kev xav ntawm kev nrhiav kev ua neeg siab zoo, yuav tsum xaiv cov iav frosted. Cov txheej txheem sandblasting feem ntau ua tau los ntawm feem ntau cov Hoobkas, tab sis kev ua tiav cov iav frosted zoo heev tsis yooj yim.
