Hauv kev siv perovskite laser engraving, qhov ruaj khov ntawm cov khoom siv ncaj qha txiav txim siab qhov tseeb ntawm kev engraving thiab qhov zoo ntawm cov khoom. Vim li cas peb cov thev naus laus zis thiaj li sawv tawm? Cov lus teb nyob rau hauv lub hauv paus granite "tsis pom" no!
1. Ib rab riam phom zais cia ruaj khov zoo li Roob Tai
Lub hauv paus ib txwm co mus rau hauv lub lim dej sai li sai tau thaum nws tig, thiab cov kab kos duab nkhaus, nrog rau qhov nrawm siab heev. Txawm li cas los xij, qhov ceev ntawm peb lub hauv paus granite yog siab heev, thiab nws qhov nyuaj yog sib piv rau cov pob zeb diamond (nrog Mohs hardness ntawm 6-7). Txawm tias qhov kub nce siab thaum lub sijhawm laser engraving, nws cov coefficient ntawm thermal expansion yog qis heev uas nws tsis tshua deforms! Cov ntaub ntawv ntsuas tau ua kom pom tseeb heev - nrog qhov sib txawv ntawm qhov kub ntawm 1 ℃, nws qhov deformation yog 200 npaug nyias dua li cov plaub hau tib neeg! Thaum cov khoom siv ua haujlwm, lub granite tuaj yeem nqus tau ntau dua 90% ntawm kev co zoo li lub paj rwb. Thaum engraving, cov kab ruaj khov zoo li lawv tau "welded" rau cov khoom siv!
Qhov thib ob, kev ua tiav high-tech ua rau muaj kev ua haujlwm raug dua
Thaum lwm tus ua lub hauv paus nrog cov txheej txheem ib txwm muaj, peb ncaj qha ntaus "daim npav trump"! Lub tshuab tswj hwm tsib-axis txuas ua ke sib tsoo lub hauv paus granite kom txawm tias tiaj dua li daim iav, nrog rau qhov yuam kev tiaj tus tswj tau hauv 0.5μm / m. Qhov no txhais tau tias dhau qhov deb ntawm 1 'meter', qhov sib txawv siab tsis tshaj 1/200 ntawm cov plaub hau tib neeg! Tsis tas li ntawd, nrog rau kev kho mob annealing 48-teev tshwj xeeb, kev ntxhov siab sab hauv raug tshem tawm tag nrho. Qhov tseeb yuav tsis ploj txawm tias tom qab peb txog tsib xyoos ntawm kev siv!
Qhov thib peb, cov nyhuv engraving yog ncaj qha divine
Lub Hoobkas nyob ib sab ntawm lub tsev no tab tom txiav cov yeeb yaj kiab perovskite, nrog rau qhov feem pua ntawm cov khoom seem txog li 15%, thiab qhov yuam kev ntawm cov kab dav tuaj yeem phem npaum li ib nrab ntawm cov plaub hau tib neeg. Cov khoom siv uas peb siv nrog lub hauv paus granite muaj cov kab ncaj thiab zoo, nrog rau qhov yuam kev dav tswj tau hauv ± 0.1μm, thiab qhov nqi ntawm cov khoom seem tau raug txo qis mus rau 3%! Ib lub tuam txhab hluav taws xob tshiab tau txais peb cov thev naus laus zis, thiab qhov ua tau zoo ntawm kev hloov pauv ntawm cov hlwb perovskite tau nce 2%, khwv tau ntau lab ntxiv hauv ib xyoos!
Xaiv lub hauv paus zoo, thiab qhov ua tau zoo ntawm kev kos duab yuav ob npaug thaum tus nqi yuav poob qis heev! Yog tias koj xav tau perovskite laser engraving sai thiab raug, tsuas yog ntseeg peb lub "cuab yeej khawv koob" granite! Nyem rau ntawm kev sab laj kom qhib qhov kev daws teeb meem engraving siab ⬇️
