Polishing yas thiab iav taub hau - cov txheej txheem pov thawj
Txheem
Lub tsheb headlights yog them los ntawm sab nraud nrog pob tshab lub kaus mom, uas ib zaug tau txais kev pab raws li deflectors ntawm lub teeb flux. Tam sim no lawv tsuas yog muab kev kho kom zoo nkauj thiab kev tiv thaiv kev ua haujlwm rau qhov nyuaj optics nyob hauv lub teeb taub hau. Nws yog ib qho tseem ceeb uas lawv ib txwm nyob twj ywm pob tshab thiab tsis txhob lwj qhov tsos ntawm lub tsheb, yog li qhov xav tau rau kev siv tshuab ua haujlwm uas qee zaum tshwm sim.
Yog vim li cas lub tsheb headlights dim?
Qhov chaw ntawm lub teeb taub hau ntawm lub cev yog xws li tias lawv noj txhua yam uas nkag mus rau hauv cov pa phem, tshuab lub tsheb ntawm kev kub ceev.
Lub kaus mom raug nthuav tawm rau ntau yam txhoj puab heev ib zaug:
- abrasive hmoov av tsa los ntawm cov tsheb nyob rau hauv pem hauv ntej thiab tom ntej tsheb;
- ntau yam tshuaj phem heev nyob rau hauv muaj pes tsawg leeg ntawm txoj kev av;
- ultraviolet tivthaiv ntawm tshav ntuj;
- Sab hauv lub teeb nyob rau hauv tib yam emissions los ntawm lub teeb taub hau, nws yog tsis muaj zog tshaj lub hnub ci, tab sis tsis txwv rau tag nrho cov pom ib feem ntawm lub spectrum;
- Qhov kub ntawm cov khoom siv hluav taws xob, halogen incandescent teeb, xenon lossis LED qhov chaw.
Tsis tas li ntawd, sab nrauv ntawm lub teeb taub hau raug kev txom nyem thaum ntxuav, yeej ib txwm muaj qee yam ntawm cov tshuaj abrasive hauv dej.
Thiab qee tus neeg tsav tsheb tawv tawv ua kom tiav cov teeb pom kev zoo, zoo li tag nrho lub cev, muaj tus cwj pwm ntawm tsuas yog so cov av nrog cov ntaub qhwv los yog daim txhuam cev nrog qhov tsawg kawg nkaus lossis tsis muaj dej.
Dab tsi yog polishing rau?
Nyob rau tib lub sijhawm, rau tag nrho cov laj thawj saum toj no, sab nraud ntawm lub hau yog npog nrog lub network ntawm microcracks. Lawv tsis pom ntawm qhov muag liab qab, tab sis daim duab ntawm kev turbidity yog pom zoo kawg nkaus. Tsis tas li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov txheej txheej saum npoo hloov.
Transparency tsuas tuaj yeem rov qab kho txhua yam, uas yog, los ntawm kev tshem tawm cov yeeb yaj kiab uas zoo tshaj plaws los ntawm cov kab nrib pleb thiab cov khoom uas tsis xa cov teeb pom kev zoo siv kev sib tsoo zoo thiab polishing.
Cov cuab yeej thiab cov khoom

- xuab zeb los ntawm cov lej, los ntawm cov ntxhib ntxhib (hauv cov ntsiab lus ntawm polishing, tsis rub lub qhov) mus rau qhov zoo tshaj plaws;
- polishing tshuab nrog hluav taws xob tsav;
- nozzles rau nws, los yog rau ib tug xyaum nyob rau hauv nws tsis muaj;
- sponges rau phau ntawv thiab txhua yam ua haujlwm;
- daim npog ntsej muag rau gluing seem ntawm lub cev;
- ntxuav cov tshuaj raws li cov tshuaj zawv plaub hau nrog lub ntsej muag zoo-active nyhuv.
Raws li txoj cai, koj tuaj yeem polish manually, tab sis cov txheej txheem yuav siv sij hawm ntau dhau. Yog li ntawd, ib qho kev sib txawv tsis tu ncua ceev polisher lossis zoo li hluav taws xob laum yuav yog ib qho kev cuam tshuam zoo ntawm phau ntawv polishing thiab tus kws tshaj lij orbital polisher.
Polishing yas taub hau
Yuav luag tag nrho cov teeb pom kev zoo tau ntev tau nruab nrog lub hau sab nraud ua los ntawm polycarbonate. Cov iav deflectors muaj tsawg thiab nyob deb ntawm.
Ib qho tshwj xeeb ntawm cov khoom siv teeb pom kev zoo yog qhov tsis tshua muaj zog ntawm txawm tias qhov zoo tshaj plaws ntawm cov yas no. Yog li ntawd, ib txheej nyias nyias feem ntau yog siv rau lawv, uas muaj hardness, yog tias tsis yog iav, ces tsawg kawg yog muab kev pab cuam lub neej.
Qhov no yuav tsum tau nco ntsoov thaum polishing thiab ua tib zoo ua, txwv tsis pub koj yuav tau rov ua dua qhov kev tiv thaiv no. Uas tsis yog li ntawd yooj yim thiab pheej yig.
Nrog tshuaj txhuam hniav
Qhov yooj yim tshaj plaws polish yog tshuaj txhuam hniav. Los ntawm qhov xwm txheej ntawm nws cov haujlwm, nws yuav tsum muaj cov hniav abrasives.
Qhov teeb meem yog tias tag nrho cov pastes sib txawv, thiab tus nqi, nrog rau cov grit thiab hardness ntawm abrasive nyob rau hauv lawv, yuav txawv ntawm xoom mus rau unacceptably siab.
Piv txwv li, whitening pastes tuaj yeem ua haujlwm zoo li cov ntawv xuab zeb ntxhib thaum siv rau lub taub hau yas, thiab txawm tias los ntawm tshuab. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua hauj lwm nrog cov muab tshuaj txhuam kom zoo thiab tom qab kev sim ua ntej, txwv tsis pub lub teeb taub hau yuav puas.
Cov txheej txheem nws tus kheej yog yooj yim heev, muab tshuaj txhuam yog siv rau saum npoo thiab polished manually nrog ib daim ntaub los yog daim txhuam cev.
Gel pastes tsis haum, tsis muaj abrasive nyob rau hauv tag nrho, cov no yog purely detergent compositions. Chalk-based los yog sodium bicarbonate pastes kuj siv me ntsis. Tsuas yog cov uas muaj silicon dioxide raws li abrasive yog tsim nyog.
Nrog cov ntawv xuab zeb
Sandpaper yog siv rau kev ua thawj zaug ntawm qhov chaw puas hnyav heev. Nws tshem tawm cov khawb kuj loj.
Qhov saum npoo tom qab ua tiav dhau los ua matte ntau dua li nws tau ua. Maj mam nce tus naj npawb (koj tuaj yeem pib ntawm 1000 lossis 1500), lawv ua tiav qhov nce ntawm qhov pom thiab ci ntawm qhov chaw, tab sis tom qab ntawd nws tseem yuav tsum tau polished.
Kev ua hauj lwm yuav tsum tau ua manually, daim ntawv yog tsau rau ntawm ib tug tshwj xeeb mos tuav. Koj tsis tuaj yeem tuav nws nrog koj cov ntiv tes xwb, kev ua haujlwm yuav tsis sib npaug vim muaj kev sib txawv ntawm cov ntawv ntawm cov ntawv.
Kev sib tsoo yog ua tiav nrog dej ntau, kev sib txhuam qhuav yog qhov tsim nyog. Raws li qhov muaj zog siab ntawm cov khoom sib tsoo.
Nrog abrasive polish thiab daim txhuam cev
Tag nrho cov abrasive polishes kuj raug faib raws li qib ntawm grit. Cov tawv tawv tshaj plaws yog siv rau kev ua haujlwm ntawm phau ntawv, kev siv tshuab tam sim ntawd "khiav qhov", uas tom qab ntawd tsis tuaj yeem tshem tawm.
Qhov tseeb, cov polish yog tib yam polishing paste, tsuas yog twb tau diluted thiab npaj siv. Lawv tau thov nyob rau hauv ib txheej nyias ntawm lub teeb taub hau thiab polished nrog ib tug haum ua npuas ncauj ncoo rau lub tshuab.
Nrog polishing muab tshuaj txhuam thiab grinder
Ib qho zoo polishing muab tshuaj yog twb npaj rau txoj cai sib xws thiab yog tsim los ua hauj lwm nrog ib tug ua npuas ncauj ncoo ntawm ib tug tej yam hardness. Cov softest discs ua haujlwm nrog cov pastes zoo tshaj plaws hauv kev ua tiav.
Cov tshuaj nplaum yog siv rau lub teeb taub hau. Yog tias koj muab tso rau hauv lub disk, ces yuav tsis muaj qhov sib txawv ntau, tshwj tsis yog kev poob loj, nws yuav ya sib nrug ntawm qhov kev txiav txim ntawm centrifugal rog. Nws yog ib qho tsim nyog yuav tsum ua haujlwm ntawm qhov nrawm, tsis siab tshaj 500 ib feeb. Yog li ntawd qhov saum npoo hnav tsawg dua, thiab qhov kev pheej hmoo ntawm overheating yog txo.
Rau cov yas, qhov no yog qhov txaus ntshai, thaum kub kub lawv dhau los ua huab thiab tig daj. Lub rotating disk yuav tsum tsis tu ncua txav nyob rau hauv ib ncig.
Periodically, txheej yog hloov kho nrog kev tswj ntawm qhov tshwm sim. Txiav tawm ntau cov khoom tsis tsim nyog, lub teeb taub hau tsuas tuaj yeem tiv taus 2-3 polishes, tom qab ntawd nws yog ib qho tsim nyog yuav tsum rov ua dua cov txheej txheem ceramic.
Yuav ua li cas polish iav taub hau
Qhov txawv tsuas yog qhov hardness ntawm cov khoom siv cap. Cov iav tsuas tuaj yeem ua tiav nrog GOI pastes lossis zoo sib xws, pob zeb diamond lossis lwm hom, npaj rau classical optics.
Sandpaper tsis siv, ib yam li phau ntawv qhia. Qhov ceev ntawm polisher tuaj yeem siab dua li ntawm cov yas. Kuj tseem muaj tshwj xeeb kho polishing rau iav. Lawv sau cov kab nrib pleb nrog polymer, thiab tom qab ntawd polish.
Nta ntawm internal polishing
Sab hauv polishing tsis yog qhov txawv ntawm kev polishing sab nraud, tab sis nws nyuaj dua vim qhov rov qab curvature ntawm qhov chaw. Tab sis nws tsis tshua xav tau.
