Ob chav fixation, tsis ntshai ntawm qhov kub thiab txias
Qhov no yog qhov tseem ceeb kom zoo dua qhov txawv ntawm cov welded hauv ob sab phlu los ntawm cov khoom nplaum ntshiab.
Muaj zog siab -kub tsis kam: Ordinary adhesive liners feem ntau tsuas yog siv nyob rau hauv ib puag ncig ntawm 100℃~ 300 degree. Nyob rau hauv cov txheej txheem tshwj xeeb, welded hauv ob sab phlu tuaj yeem tiv taus qhov kub txog li 650℃lossis txawm 750 degree, daws cov teeb meem ntawm cov nplaum laus thiab hauv ob sab phlu phaj detachment ntawm qhov kub thiab txias. Nws yog qhov tsim nyog rau kev siv rau siab - cov kav dej kub xws li lub zog cog cua ducts thiab cov cement cog tertiary cua ducts.
Kev tiv thaiv ntau dua rau kev cuam tshuam thiab kev co: Rau cov khoom siv xws li chutes, hoppers, lossis vibrating screens nrog cov khoom loj poob thiab muaj zog cuam tshuam, cov khoom siv ceramic uas tsuas yog ua rau cov nplaum tuaj yeem yooj yim poob rau hauv lub sijhawm ntev - kev co. Txoj kev vuam muab kev sib txuas ntawm cov khoom siv dag zog, ua rau cov phaj hauv ob sab kom ruaj khov thiab txo qhov kev pheej hmoo ntawm detachment nyob rau hauv siab vibration thiab muaj zog tej yam kev mob.
Ceramics lawv tus kheej yog "hnav-tiv taus thiab hnav"
Ntawm lub hauv paus ruaj khov, nws tau txais cov yam ntxwv zoo ntawm alumina ceramics:
Kev hnav siab heev: Lub hardness ntawm alumina ceramics yog siab heev (Mohs hardness tuaj yeem ncav cuag qib 9, Rockwell hardness HRA80-90), thib ob tsuas yog pob zeb diamond, thiab nws hnav tsis kam tshaj qhov hnav-tiv taus hlau, stainless hlau thiab lwm yam ntaub ntawv. Siv nyob rau hauv cov kav dej rau kev thauj cov thee, tshauv, thiab ntxhia hmoov, kev pabcuam lub neej tuaj yeem txuas ntxiv ntau zaus piv rau cov hlau zoo tib yam.
Lub teeb yuag thiab txo cov khoom siv thauj khoom: Qhov ntom ntawm alumina ceramics yog kwv yees li 3.6g / cm³, uas yog ib nrab ntawm cov hlau. Qhov no txhais tau hais tias nrog rau tib qhov chaw tiv thaiv, qhov hnyav ntxiv yog tsawg dua, ua rau cov cuab yeej ua haujlwm ntawm kev ua haujlwm thiab cov qauv kev txhawb nqa ntau tus phooj ywg.
Qee cov qauv khoom siv
Nyob rau hauv kev siv tswv yim, welded hauv ob sab phlu daim hlau tau tsim ntau yam kev txhawb zog ntxiv rau cov pa pav ca. Piv txwv li, muaj ib tug stud welding hom uas siv studs nrog soj ntsuam bolts rau vuam, uas yog hais tias muaj kev ntseeg siab ntawm ntau tshaj 99%, siab tshaj qhov chaw vuam; Kuj tseem muaj kev sib nrig sib cuam tshuam hom, uas muaj chamfered npoo ntawm ob sab phaj. Tom qab kev teeb tsa, cov vuas luaj ceramic uas nyob ib sab tuaj yeem cuam tshuam nrog ib leeg yam tsis muaj qhov khoob, ua kom nruj dua.
Nyob rau hauv cov ntsiab lus, cov welded hnav-resistant ceramic hauv ob sab phlu, nrog nws cov "ceramic hnav tsis kam" thiab "welding fixation", tshwj xeeb tshaj yog haum rau hnyav ua hauj lwm tej yam kev mob uas muaj xws li kub, tej yam, thiab hnyav hnav tib lub sij hawm. Nws tuaj yeem daws tau cov teeb meem ntawm kev hnav tsoos tsoos- cov ntaub ntawv tiv thaiv tau yooj yim rau kev tshem tawm thiab muaj lub neej ua haujlwm luv luv.
