PTFE haanta kaydinta dahaaran ee Hydrofluoric Acid

Farsamada Muhiimka ah: Isticmaalka RANA ee farsamada PTFE ee taageerta tignoolajiyada liner fiberglass, xalkani wuxuu wax ka qabanayaa wasakhnimada ba'an ee hydrofluoric acid (HF) - shay awood u leh inay daxaliyaan dhalooyinka iyo biraha. Iyada oo loo marayo isku-buufin kulaylka, xargaha ayaa ku guuleysta is-dhexgalka aan kala go 'lahayn ee qaab dhismeedka taangiga. Iska caabbinta daxalka ee gaarka ah ee PTFE waxay gabi ahaanba u adkaysataa nabaad guurka HF, taasoo ka dhigaysa ka kaliya ee aan{2}}malax bir ah badbaado u ah kaydinta HF.

Edge tartanka: Iyada oo lala kaashanayo Jaamacadda Bariga Shiinaha ee Sayniska iyo Teknolojiyada, kooxdayada farsamada ayaa soo saartay alaabooyin muujinaya iska caabbinta daxalka HF. Xaqiijiyay hoggaamiyeyaasha warshadaha oo ay ku jiraan SMIC iyo Juhua Co., Ltd. (oo muujinaya wax hoos u dhac ah ka dib sanadaha 3 ee 40% HF xallinta immersion), waxqabadkani wuxuu aad uga sarreeyaa weelasha caaga ah ee caadiga ah (kaas oo kaliya 1 sano ka dib). Intaa waxa dheer, waxaanu ku shaqaynaa Shiinaha PPB/PPT{7}} xarunta ugu weyn ee qolka nadiifka ah, oo leh dahaarka daboolaya heerka elektiroonigga ah{8} heerarka nadaafadda ee si wax ku ool ah uga hortagaya wasakhaynta HF ee agabka elektiroonigga ah ee saafiga ah-

Xaaladaha codsiga: ugu horayn u adeega{0}} waaxyaha wax soo saarka sare ee ay ku jiraan semiconductors iyo photovoltaics. Nidaamyada nadiifinta wafer-ka yar-yar, haanta kaydinta waxay hubisaa sii haynta xalalka HF deggan si looga hortago wasakhowga birta ee dusha sare ee waferka. Inta lagu jiro marxaladda qoraalka unugyada sawir-qaadista, tignoolajiyadeeda sare - tignoolajiyada dahaarka nadiifka ah waxay dammaanad qaadaysaa nadiifnimada xalka HF, si kor loogu qaado waxtarka beddelka sawir-qaadka unugyada.
