Ntau tus neeg muaj lus nug txog qhov "stabilized tree" txhais li cas. Qhov no yog cov khoom siv uas tau dhau los ua haujlwm tshwj xeeb thiab tau txais cov yam ntxwv zoo nkauj thiab lub zog ntxiv, thaum lub ntuj qauv tseem tsis hloov pauv.
Kev piav qhia
hom kev ua haujlwm no feem ntau hu ua kev txuag, uas yog qhov tsim nyog, txij li lub luag haujlwm tseem ceeb yog khaws cia thiab txhim kho cov ntoo zoo. Tau txais cov txiaj ntsig zoo li no yog ua tau los ntawm kev siv cov khoom tshwj xeeb uas ua rau lub qhov hws thiab tawv. Resins, polymeric thiab xim-thiab-lacquer compositions, ntau cov roj tau txais kev faib loj tshaj plaws.
Stabilized ntoo kiag li nqus cov xim muaj pes tsawg leeg thiab tau txais qhov ntxoov ntxoo tshiab tsis yog rau saum npoo, tab sis thoob plaws hauv cov qauv. Muaj ntau yam kev xaiv xim, los ntawm ntuj mus rau lub suab nrov.
Ntse
Txhawm rau kom tau txais qhov txiaj ntsig zoo, yuav tsum tau npaj txhij thiab ua tib zoo ua raws li txhua txoj cai tsim. Nws tsis yooj yim rau koj tus kheejtsim cov theem tsim nyog ntawm lub siab, lub tshuab nqus tsev thiab ib qho kev ntsuas kub, tab sis tsis muaj cov xwm txheej no, kev txuag yuav ua tsis tau.
Ua ntej koj yuav tsum xaiv lub workpiece kom raug. Feem ntau, nws yog cov khoom siv zoo nkauj dhau los thiab cov qauv, nws tuaj yeem ua tau ntau yam ntoo: txiv ntseej, elm, maple, birch.
tsob ntoo ruaj khov tau txais cov khoom hauv qab no:
- hardness;
- density;
- tawm tsam rau ntau yam roj thiab cov kuab tshuaj organic;
- kev ua haujlwm zoo nkauj zoo nkauj;
- stabilized ntoo khaws nws cov khoom txawm tias thaum tshav kub los ntawm qhov qhib nplaim taws.
Cov kauj ruam no tuaj yeem ua tau los ntawm ntau txoj hauv kev:
- High pressure stabilization. Txhawm rau ua qhov no, lub thawv xaiv tau ntim nrog cov khoom sib xyaw ua ke uas lub workpiece yog raus. Tom qab ntawd lub thawv yog muab tso rau hauv ib qho tshwj xeeb chamber nyob rau hauv uas nce siab yog tsim. Lub hauv paus ntsiab lus ntawm kev txiav txim yog tias huab cua raug thawb tawm ntawm qhov chaw ua haujlwm, thiab qhov chaw seem yog ntim nrog mortar.
- Nqus txoj kev. Cov khoom yog muab tso rau hauv ib lub chamber, los ntawm cov huab cua yog tom qab tso tawm, thiab nws kuj tawm ntawm workpieces. Yog li cov tshuaj tau yooj yim stains capillaries thiab khoob pores.
- Kub impregnation. Ntoo yog boiled los yog soaked nyob rau hauv tshwj xeeb compounds. Cov khoom siv yog tus cwj pwm los ntawm liquefaction thaum rhuab, vim nws yog qhov tseem ceebnce fluidity thiab filling zoo.
- Cold impregnation yog qhov zoo tshaj plaws rau nyias workpieces.
YPolymerization
txheej txheem no ua tiav cov txheej txheem thiab ua tiav los ntawm kev ziab cov khoom ntawm qhov kub thiab txias. Cov ntoo ruaj khov rau cov tes tuav tau txais cov yam ntxwv tshiab uas ua rau nws zoo ib yam li cov ntaub ntawv polymeric, nws kuj hloov nws qhov ntxoov ntxoo thiab qhov hnyav. Nyob rau tib lub sijhawm, qhov zoo ntawm cov fibers tseem nyob rau tib theem, lawv kuj txhim kho cov kev daws teeb meem uas siv hauv kev ua haujlwm, vim tias qhov zoo nkauj thiab zoo nkauj ntawm tag nrho cov khoom ua haujlwm tau tsim. Nws yog ib qho tsim nyog sau cia tias qee yam ntawm cov khoom siv nyob rau theem no yog tus kheej-hardening.
Yuav ua li cas kom ruaj khov ntoo rau riam tuav
Cov khoom siv ua tiav yog tsim los tsim ntau yam khoom siv tes ua thiab khoom siv tes ua. Feem ntau nws yog siv rau hauv kev tsim khoom tshwj xeeb rau cov riam.
Ib qho ntawm cov khoom siv khaws cia nrov yog "Anakrol-90", qhov dej ntawm qhov chaw nyob hauv 90 degrees. Rau kev ua haujlwm, lub tshuab nqus tsev yog xav tau, nws tuaj yeem ua los ntawm cov khoom hauv qab no: lub ntsuas siab, compressor, lub tshuab nqus tsev twj, ob peb lub raj, cov thawv yas loj. Tom qab ntawd, cov ntoo ruaj khov tau qhuav rau hauv qhov cub tshwj xeeb; thaum nws tsis tuaj, koj tuaj yeem siv cua grill lossis qhov cub.
Lub thickness ntawm cov khoom siv yuav tsum tsis txhobTshaj li 3-4 cm, qhov no yog qhov tsim nyog rau kev ua haujlwm zoo impregnation.
Lub phaj ntoo muab tso rau hauv lub thawv nrog cov tshuaj, thaum nws yuav tsum tau them tag nrho nrog anacrol. Lub tshuab nqus tsev yog tsim kom txog thaum tsis muaj cua npuas ntxiv lawm.
Tom ntej no, kev kub siab yog tsim, qhov sib xyaw ua ke yuav tsum xub daws rau ib nrab teev. Lub siab yuav tsum ncav cuag 2-4 atm, rau qhov no koj yuav tsum tau siv lub twj tso kua mis thiab compressor. Cov txheej txheem yuav tsum tau rov ua dua tom qab 40 feeb. Kev nqis tes ua yog ua kom txog thaum cov khoom tso rau hauv dej. Nyob rau hauv rooj plaub no, tsis muaj kev tsis ntseeg txog qhov zoo ntawm impregnation ntawm workpiece.
Tom qab ntawd ua-nws-koj tus kheej stabilized ntoo yog kom qhuav ntawm qhov kub ntawm li 100 degrees. Tom qab nws yuav tsum tau dawb ntawm cov nqaij nyoos. Cov txheej txheem zoo li no muab ntau dua rau cov khoom siv thiab txhim kho qhov zoo ntawm polishing. Cov qauv tint uas tsis yog tus qauv tuaj yeem tau txais los ntawm kev ntxiv ntau yam pigments rau qhov muaj pes tsawg leeg. Tsis tas li niaj hnub no koj tuaj yeem nrhiav tau ntawm kev muag khoom npaj cov kev daws teeb meem uas muaj ntau yam ntxoov ntxoo.
Epoxy resin daim ntawv thov
Txoj kev no zoo ib yam li kev khaws cia anacrol, qhov sib txawv tseem ceeb yog nws hloov nrog epoxy tov nrog cawv. Cov tom kawg yog siv los txhim kho qhov zoo ntawm impregnation. Ua hauj lwm nrog resin yuav tsum tau ua siab ntev, raws li nws yuav siv sij hawm ntev rau polymerize rau lub xeev xav tau. Muaj ntau ntau yam kev daws teeb meem raws li epoxy resin. stabilized ntoo raucov lis dej num uas tshwm sim los ntawm daim ntawv thov ntawm cov dej sib xyaw no muaj cov yam ntxwv zoo tshaj plaws.
