Autoclaves tau siv niaj hnub no hauv ntau qhov kev lag luam, xws li kev tsim khoom sib xyaw thiab kev kho cua sov hlau.Ib qho kev lag luam autoclave yog lub tshuab cua kub siab nrog lub qhov rooj qhib ceev uas siv lub siab siab los ua cov ntaub ntawv kho mob.Nws siv cov cua sov thiab siab siab los kho cov khoom lossis tshuaj tua kab mob, cov khoom siv, thiab cov cuab yeej siv.Ntau hom autoclaves yog tsim xws li roj hmab bonding / vulcanizing autoclaves, composite autoclaves, thiab ntau lwm yam kev lag luam autoclaves.Autoclaves tau siv ntau hauv kev lag luam los pab hauv kev tsim cov khoom siv polymeric.

Cov txheej txheem ntawm nws pib claving tso cai rau cov tuam txhab tsim cov ntaub ntawv zoo tshaj plaws.Lub tshav kub thiab siab nyob rau hauv ib qho autoclave yog siv rau ntau yam khoom, pab txhim kho tag nrho cov khoom zoo thiab lub zog ntawm cov khoom no.Yog li ntawd, cov tshuab thiab cov dav hlau siv hauv kev lag luam aviation muaj peev xwm ua tau raws li qhov xav tau ib puag ncig.Autoclave manufacturers tuaj yeem pab tsim cov autoclaves uas tuaj yeem tsim cov khoom zoo.

Thaum cov khoom sib xyaw raug tsim thiab kho, lub siab nyob rau hauv ib puag ncig autoclave muab tso rau hauv qhov xwm txheej uas lawv dhau los ua hluav taws kub heev vim muaj zog thiab kub hauv lub autoclave.Txawm li cas los xij, thaum kho tiav, cov khoom no muaj kev nyab xeeb thiab qhov kev pheej hmoo ntawm combustion yog ze li tshem tawm.Thaum lub sij hawm kho cov txheej txheem no cov composites tuaj yeem combust yog tias cov xwm txheej raug yeej - piv txwv li, yog tias oxygen tau nkag.Nitrogen yog siv nyob rau hauv autoclaves vim nws yog pheej yig thiab yog inert, yog li yuav tsis ntes hluav taws.Nitrogen tuaj yeem tshem tawm cov pa roj no kom nyab xeeb thiab txo qhov kev pheej hmoo ntawm hluav taws kub hauv autoclave.

Autoclaves tuaj yeem hloov pauv nrog huab cua lossis nitrogen, nyob ntawm cov neeg siv khoom xav tau.Kev lag luam tus qauv zoo li tias huab cua tsis zoo mus txog qhov kub ntawm ib puag ncig 120 deg C. Tshaj qhov ntsuas kub no, nitrogen feem ntau yog siv los pab hloov cua sov thiab txo qhov muaj peev xwm hluav taws kub.Cov hluav taws kub tsis tshua muaj, tab sis lawv tuaj yeem ua rau muaj kev puas tsuaj ntau rau autoclave nws tus kheej.Kev poob tuaj yeem suav nrog kev thauj khoom tag nrho ntawm cov khoom thiab cov khoom siv qis thaum lub sijhawm kho.Hluav taws kub tuaj yeem tshwm sim los ntawm cov cua sov hauv cheeb tsam los ntawm lub hnab xau thiab cov txheej txheem resin exotherm.Thaum lub zog siab dua, muaj oxygen ntau dua los pub hluav taws.Txij li tag nrho sab hauv ntawm lub nkoj siab yuav tsum tau muab tshem tawm los tshuaj xyuas thiab kho lub autoclave tom qab hluav taws kub, nitrogen them nyiaj yuav tsum tau txiav txim siab.*1

Lub kaw lus autoclave yuav tsum xyuas kom meej tias qhov yuav tsum tau muaj tus nqi siab hauv autoclave tau ua tiav.Qhov nruab nrab qhov siab ntawm cov autoclaves niaj hnub no yog 2 bar / min.Niaj hnub no, ntau lub autoclaves siv nitrogen los ua qhov nruab nrab ntawm cov cua.Qhov no yog vim hais tias autoclave kho consumables yog heev inflammable nyob rau hauv cov huab cua nruab nrab vim muaj oxygen.Muaj ntau cov lus ceeb toom ntawm qhov hluav taws kub autoclave uas ua rau muaj qhov tsis sib xws hauv qhov poob ntawm cov khoom.Txawm hais tias qhov nruab nrab nitrogen ua kom tsis muaj hluav taws kub tsis muaj kev kho mob autoclave, yuav tsum tau saib xyuas kom tsis txhob muaj kev phom sij rau cov neeg ua haujlwm (muaj peev xwm ntawm asphyxiation) nyob rau hauv ib puag ncig nitrogen vim tias cov pa oxygen qis dua.
