Ntim, Thauj thiab Cia
Cov nplooj ntawv yuav tsum muab khaws cia rau hauv qhov chaw uas qhov kub tsis siab tshaj 40 ℃, thiab muab tso rau hauv kab rov tav ntawm lub txaj nrog qhov siab ntawm 50 hli lossis siab dua.Khaws kom deb ntawm hluav taws, cua sov (cov cuab yeej cua sov) thiab ncaj qha tshav ntuj.Lub neej cia ntawm nplooj ntawv yog 18 lub hlis txij li hnub tawm hauv lub Hoobkas.Yog tias lub sijhawm khaws cia ntev dua 18 lub hlis, cov khoom siv kuj tuaj yeem siv tom qab kuaj kom tsim nyog.
Lus ceeb toom thiab ceev faj rau daim ntawv thov
Kev kub ceev thiab me me txiav qhov tob g yuav tsum tau siv thaum machining vim cov nplooj ntawv tsis muaj zog thermal conductivity.
Machining thiab txiav cov khoom no yuav tso tawm ntau plua plav thiab pa taws.Kev ntsuas tsim nyog yuav tsum tau ua kom ntseeg tau tias cov plua plav plua plav nyob rau hauv cov kev txwv uas tau txais thaum ua haujlwm.Kev tso pa tawm hauv zos thiab siv cov plua plav/particle qhov ncauj qhov ntswg raug qhia.
Cov nplooj ntawv yuav tsum tau ya raws tom qab raug machined, ib txheej ntawm insulating vanish yog pom zoo.
