Taw qhia
Hauv kev kho hniav, cov neeg sawv cev sib txuas ua lub luag haujlwm tseem ceeb hauv kev tsim kom muaj kev sib raug zoo ntawm cov qauv hniav thiab cov khoom siv kho dua tshiab. Ib tus neeg sawv cev sib txuas tuaj yeem txhais tau tias yog ib hom kev kho hniav nplaum uas feem ntau muaj cov khoom sib xyaw ua ke thiab lwm yam sib xyaw. Cov khoom siv kho hniav yog ib qho yuav tsum muaj rau kev sib txuas cov khoom sib txuas thiab lwm yam khoom siv kho hniav rau cov qauv hniav.
Peb kauj ruam kev sib txuas cov neeg ua haujlwm yog qhov kev xaiv nrov thiab tau siv dav rau kev sib txuas ntau yam khoom siv kho hniav. Kab lus no yuav muab kev tshuaj xyuas qhov tob ntawm peb-kauj ruam kev sib txuas cov neeg ua haujlwm thiab lawv cov txheej txheem ntawm kev ua.
Dab tsi yog peb-kauj ruam sib txuas cov neeg ua haujlwm?
Peb-kauj ruam sib txuas cov neeg ua haujlwm yog ib hom kev kho hniav nplaum uas muaj peb kauj ruam cais. Thawj kauj ruam yog siv cov etchant uas muaj phosphoric acid rau ntawm cov hniav. Lub etchant ua haujlwm los ntawm kev tsim qhov roughness thiab micro-porosity nyob rau hauv cov qauv ntawm cov hniav los txhim kho cov kev sib raug zoo ntawm cov hniav thiab cov khoom siv kho dua tshiab.
Cov kauj ruam thib ob suav nrog kev siv cov primer, uas muaj cov kuab tshuaj organic thiab bifunctional monomer. Cov organic solvent evaporates thiab tawm ib txheej nyias ntawm bifunctional monomer rau ntawm cov hniav npaj. Lub bifunctional monomer tsim cov tshuaj sib txuas nrog ob qho tib si cov qauv hniav thiab cov khoom siv cob.
Cov kauj ruam thib peb yog siv cov khoom sib txuas los yog cov nplaum, uas muaj cov khoom sib xyaw ua ke uas muaj ob qho tib si hydrophilic thiab hydrophobic zog. Lub hydrophilic resin tivthaiv tsim cov tshuaj lom neeg nrog cov dej molecules tam sim no nyob rau hauv cov qauv hniav. Lub hydrophobic resin tivthaiv tsim cov tshuaj lom neeg nrog cov khoom siv cob. Cov txiaj ntsig tau txais lub zog yog kev sib xyaw ua ke ntawm cov tshuaj sib txuas ntawm cov qauv hniav thiab cov khoom siv cob, thiab cov khoom siv hluav taws xob vim qhov roughness thiab micro-porosity tsim los ntawm etchant.
Qhov zoo ntawm peb-kauj ruam sib txuas cov neeg ua haujlwm
Peb-kauj ruam sib txuas cov neeg ua haujlwm muaj ntau qhov zoo dua li lwm hom kev sib koom ua ke. Ua ntej, lawv muab lub zog zoo heev vim yog kev sib xyaw ntawm cov tshuaj thiab cov khoom siv sib txuas. Qhov thib ob, lawv muaj cov txheej txheem tsis tshua muaj siab, uas txhais tau hais tias lawv zam ntau dua rau qhov kev hloov pauv me ntsis hauv cov txheej txheem tsis cuam tshuam rau lub zog ntawm daim ntawv cog lus. Thib peb, lawv tuaj yeem siv tau rau hauv cov xwm txheej uas muaj kev pheej hmoo ntawm cov kab mob ya raws, xws li thaum muaj qaub ncaug lossis ntshav.
Qhov tsis zoo ntawm peb-kauj ruam kev sib txuas cov neeg ua haujlwm
Kuj tseem muaj qee qhov kev txwv rau kev siv peb-kauj ruam sib txuas cov neeg ua haujlwm. Ua ntej, lawv xav tau ob peb kauj ruam, uas tuaj yeem siv sijhawm ntev thiab ua rau muaj kev pheej hmoo ntawm kev sib kis. Qhov thib ob, lawv xav tau ib qho etchant uas muaj phosphoric acid, uas tuaj yeem ua rau over-etching thiab tsim muaj peev xwm rau cov hniav rhiab heev. Thib peb, tus neeg sawv cev sib txuas tsuas tuaj yeem sib txuas rau cov qauv hniav uas npaj tau, uas txhais tau hais tias nws tsis tuaj yeem khi rau cov qauv hniav uas tsis tau npaj los yog cov khoom qub qub.
Xaus
Hauv kev xaus, peb-kauj ruam kev sib txuas cov neeg ua haujlwm yog ib qho kev xaiv nrov hauv kev kho hniav rau kev sib txuas cov resins thiab lwm yam khoom siv kho kom zoo nkauj rau cov hniav. Lawv muab lub zog zoo heev vim yog kev sib xyaw ntawm cov tshuaj lom neeg thiab cov khoom siv sib txuas, thiab muaj cov txheej txheem tsis tshua muaj siab. Txawm li cas los xij, lawv xav tau ob peb kauj ruam thiab tuaj yeem siv sijhawm ntev. Ua tib zoo xav txog qhov zoo thiab cov kev txwv ntawm peb-kauj ruam kev sib raug zoo yog qhov tseem ceeb thaum xaiv tus neeg sawv cev sib raug zoo rau txhua qhov chaw kho mob.
