Piv nrog rau qhov qubtungsten hlau, tungsten xov hlau rau photovoltaics muaj cov khoom zoo dua qub, xws li lub zog tensile ntau dua thiab muaj kev cuam tshuam zoo dua, yog li lawv tsim nyog dua li busbars (substrates) ntawm cov pob zeb diamond hlau, uas tuaj yeem txo qhov Disconnection tus nqi, txhawm rau txhim kho kev ua haujlwm ntawm silicon. wafer cov tuam txhab tsim khoom thiab txuag cov nqi tsim khoom.
Los ntawm cov tshuaj lom neeg pom, cov yam ntxwv cuam tshuam rau kev ua haujlwm ntawm tungsten hlau rau photovoltaics suav nrog tsis yog tsuas yog qhov zoo thiab qhov sib piv ntawm cov khoom siv raw tab sis kuj yog cov txheej txheem tsim khoom thiab cov txheej txheem tsis ua haujlwm. Cov txheej txheem ntau lawm ntawm tungsten hlau yog txheej txheem nyuaj thiab nyuaj. Tag nrho cov txheej txheem yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias lub cev thiab tshuaj lom neeg ntawm cov hlau tungsten tiav los ntawm kev tswj cov tshuaj tsim nyog.
Cov kauj ruam ntawm doped tungsten hlau: cov khoom siv raw ammonium paratungstate (APT) yog txo los ntawm hydrogen, tom qab ntawd doped nrog lanthanum, tom qab ntawd txo qis dua, tom qab pickling thiab impurity tshem tawm kom tau txais high-purity tungsten-lanthanum hmoov; tungsten-lanthanum hmoov yog raug rau isostatic Cov khoom semi-tiav yog tau los ntawm nias thiab sib sau, thiab tom qab ntawd pre-sintered thiab vertically sintered; Tom qab ntawd cov khoom siv sintered vertically yog raug rau kev sib tsoo forging thiab nruam rotary forging los yog forging, ua raws li electrolytic tu, ua raws li high-frequency annealing thiab vuam; Thaum kawg, nruam Rotary forging, hlau kos duab, ntim.
Cov txheej txheem ntawm doped tungsten hlau yog ammonium paratungstate → thawj txo → doping → theem nrab txo → pickling → mixing → isostatic nias → pre-sintering → rauj melting → swaging blanking → nruam swaging los yog forging → electrolysis ntxuav → high zaus annealing → welding nruam swaging → xaim kos duab → tshuaj xyuas → khaws cia → rov ua dua.
Los ntawm qhov pom ntawm cov txheej txheem tsim khoom, cov cuab yeej koom nrog hauv kev tsim cov doped tungsten hlau feem ntau suav nrog APT calcination khoom, APT txo cov cuab yeej, isostatic xovxwm, sintering rauv, teb rauj forging tshuab, nruab nrab zaus sintering rauv, tungsten hlau kos duab tshuab thiab tshuaj xyuas thiab kuaj cov cuab yeej rau txhua qhov txuas.
Cov txheej txheem ntau lawm ntawm high-purity tungsten hlau thiab high-temperature-resistant tungsten hlau tsim los ntawm Baoji Yusheng Hlau Technology Co., Ltd. yog yeej ib yam. High-temperature-resistant tungsten hlau yog tam sim no feem ntau siv nyob rau hauv kev tsim thiab sib dhos ntawm ntau yam hluav taws xob lub teeb qhov chaw thiab lwm yam lag luam. Cov xaim xaim tuaj yeem muab rau koj nrog ntau yam tshwj xeeb ntawm tungsten hlau cov khoom, txais tos nug kom paub ntau ntxiv txog cov khoom lag luam!
