- construction - flooring, tsev sab nrauv, ru tsev, chav kho kom zoo nkauj thiab ua rooj tog;
- rau kev tsim phom thiab chaw ua kis las;
- rau cov khoom me me thiab ntau dua.
txheej txheem kom tau cov kua roj vanish
Txhawm rau ua kom muaj qhov sib xyaw, koj yuav tsum siv cov tshuaj hauv qab no: phenol, ethyl cawv, formalin thiab ammonia. Dab tsi ntawm cov kua roj vanish bakelite peb paub? Lawv nyob ntawm tus yam ntxwv ntawm cov khoomtshuaj.
yam ntxwv ntawm cov khoom siv
Yog li, thawj cov tshuaj yog phenol. Nws yog ib qho organic compound uas dissolves thaum interacting nrog dej. Nws qhov chaw khov yog 40ºС. Formalin yog ib yam tshuaj lom uas txaus ntshai uas suav tias yog tshuaj lom. Nws yog cov kua ntshiab uas tsis tshua muaj kev cuam tshuam. Ammonia tsis yog siv rau hauv nws daim ntawv dawb huv, tab sis cov tshuaj tsis muaj zog aqueous yog tsim los ntawm nws.
Ethyl cawv yog siv los tso cov tshuaj carbonaceous. Qhov kawg tshwm sim yog kua ntshiab. Nws tuaj yeem dyed nyob rau hauv ntau yam xim. Cov kua roj vanish kuj muaj cov roj zaub thiab cellulose. Nws ua tib zoo ua ntej muab ntxiv.
hom tsiaj
Hnub no, muaj 9 yam tseem ceeb ntawm bakelite varnishes. Txhua tus ntawm lawv yog siv rau hauv ib qho kev lag luam tshwj xeeb. Tsis tas li ntawd, lawv muaj cov feem pua ntawm cov khoom sib txawv, uas yog, phenol, formaldehyde, ethanol thiab ammonia. Nrog rau kev hloov pauv ntawm ib qho ntawm cov ntsuas, cov khoom ntawm cov kua roj vanish thiab nws cov haujlwm hloov. Piv txwv li, koj tuaj yeem sib piv cov npe ntawm cov kua roj vanish:
- SBS-1 - rau kev ua cov yas thiab plywood, uas yog siv rau sab nrauv thiab sab hauv tsev.
- LBS-4 - rau ntau yam yas uas muaj cov ntxhia pob zeb.
- LBS-1 thiab LBS-2 yog suav tias yog cov kua roj vanish zoo tshaj plaws thiab siv los pleev xim yas thiab iav textiles.
Cov kua roj vanish yog siv rau saum npoo ntawm cov khoom siv hauv tsev lossis qhov chaw nrog txhuam lossis cov menyuam. Yog li ntawd, ib zaj duab xis tshwj xeeb yog tsim rau saum npoo, muaj cov organic lossis inorganic ntsiab. Nws tiv thaiv qhov chaw los ntawm ya raws thiab lwm yam khoom hnyav.
Kho siv
hom kua roj vanish no yog siv rau kev ua haujlwm sab hauv thiab sab nrauv. Nrog kev pab los ntawm cov xim tshwj xeeb, koj tuaj yeem ua tiav cov xim uas xav tau ntawm cov khoom. Hauv qhov no, cov khoom ntawm cov kua roj vanish yuav nyob twj ywm tsis hloov. Txawm li cas los xij, nws siv hauv tsev yog qhov nyuaj.

Hauv qhov no, qhov kub yuav tsum ncav cuag 160ºС. Yuav kom ua tiav, koj yuav tsum ua haujlwm hnyav.
Natural ziab ntawm qhov chaw yog nqa tawm rau 4 teev. Rau kev tiv thaiv zoo dua, txheej thib ob yog siv rau saum, uas muaj cov muab tub lim tshwj xeeb. Tag nrho cov tom ntej tuaj tsis muaj qhov muab tub lim. Thaum kawg, zaj duab xis thickness ncav cuag 0.5mm.
Txhawm rau kom muaj zog txhua yam ntawm qhov chaw, paj rwb ntaub yog siv, uas yog impregnated nrog bakelite kua roj vanish. Nws yog nteg nyob rau hauv txog 3 txheej. Cov tshuab no yog raws li hauv qab no: ua ntej, cov ntaub yuav tsum tau ntxuav kom huv si thiab qhuav kom tshem tau cov hmoov txhuv nplej siab.
Nws yog txiav rau hauv me me thiab muab tso rau hauv lub thawv nrog kua roj vanish. Nws yuav tsumsoak rau 5 feeb. Tom ntej no, cov ntaub yog muab tshem tawm ntawm lub thawv thiab nyem nrog roj hmab hnab looj tes. Cov impregnated pieces yog coj tawm mus rau hauv qhov qhib cua thiab qhuav kom lub xub ntiag ntawm cov kuab tshuaj yog minimized. Cov ntaub primed thiab qhuav yog siv rau saum npoo thiab cov kua roj vanish yog thov rau saum nrog txhuam. Yog tias muaj kev xav tau los ua kom lub zog txhua yam ntawm cov kav dej, ces cov ntaub yog txiav mus rau hauv ib daim hlab me me dav. Ces tus txheej txheem ua raws tib tus qauv.
Thaum kawg, ib zaj duab xis yog tsim rau ntawm lub tsev nto, uas yuav tiv thaiv cov khoom los ntawm ya raws thiab lwm yam. Nws tuaj yeem raug puas tsuaj raws li ntau yam xwm txheej:
- yog tias qhov chaw yuav raug kub siab tshaj 20 ºС rau lub sijhawm ntev;
- yog tias cov varnished nto raug tshav ntuj ncaj qha.
