Ntawm ntau yam ntawm cov kua roj vanish, bituminous occupies ib qho chaw tshwj xeeb. Ob peb xyoos dhau los, nws txoj kev siv tau poob qis heev. Nws yog tsuas yog siv rau kev ua lub tsheb qhov chaw. Tab sis tsis ntev los no, ib tug fashionable qauv nyob rau hauv lub sab hauv tsim tau tshwm sim - dag aging. Thiab qhov kev thov rau cov kua roj vanish bituminous tau nce ntxiv.
Production Features
Cov cuab yeej no yog ua raws li bitumen. Tab sis muab cov kev daws teeb meem qee yam kev ua haujlwm (piv txwv li, plasticity, tshav kub tsis kam), resins ntxiv. Lawv yog ob hom: hluavtaws thiab ntuj. Cov tom kawg suav nrog cov paub zoo rosin. Ntawm cov khoom siv dag zog, xws li cov resins xws li copals tuaj yeem paub qhov txawv. Thaum lub sij hawm tsim cov txheej txheem, cov sib tov yog rhuab mus rau high kub (280 degrees), thiab ces txias thiab hnyav ntxiv. Yav dhau los, turpentine feem ntau yog siv, niaj hnub no, ntxiv rau nws, hnyav, dawb ntsuj plig, los yog sib tov ntawm cov khoom no yuav siv tau. Txawm li cas los xij, bituminous kua roj vanish kuj yog raws li cov roj. Raws li txoj cai, linen lossis tung yog siv rau lub hom phiaj no. Cov ntsev ntawm fatty acids ntxiv rau lawv - manganese, cob alt, txhuas. Yog li thiabtau ib tug bituminous kua roj vanish. Yuav hnub no yog ib qho yooj yim.
Bituminous kua roj vanish: specifications
Kev siv cov kua roj vanish yog vim nws cov yam ntxwv. Ntawm lawv yog cov hauv qab no:
- Yplasticity;
- tiv taus qhov kub thiab ntau yam tshuaj;
- moisture resistance.
Muaj kev xav tias cov kua roj vanish bituminous muaj cov khoom tiv thaiv corrosion, uas yog vim li cas nws thiaj li siv los tiv thaiv cov khoom hlau. Qhov tseeb qhov no tsis muaj tseeb. Raws li kev cuam tshuam ntawm atmospheric agents, nws tsuas tuaj yeem tiv thaiv xeb rau ib ntus. Yog li ntawd, nws ua cov khoom lag luam uas yuav tsum tau tiv thaiv lub sijhawm luv luv - 6 lub hlis, yog tias kev kho mob ua tiav nrog ib txheej ntawm cov kua roj vanish. Kev siv cov cuab yeej no rau lub hom phiaj no feem ntau vim tias nws muaj tus nqi qis.
Bitumen kua roj vanish muaj ntau yam. Kev faib tawm yog nyob ntawm cov khoom tseem ceeb ntawm cov khoom sib xyaw. Txog rau hnub tim, cov kua roj vanish BT-123 yog nyob rau hauv qhov kev thov, cov yam ntxwv uas tso cai rau nws siv tsis tau tsuas yog ua tus neeg sawv cev tiv thaiv rau cov hlau thiab cov hlau tsis yog hlau. Feem ntau qhov sib xyaw no yog siv rau kev tsim cov xim txhuas. Nyob rau tib lub sijhawm, cov khoom siv tshwj xeeb kuj tau ntxiv uas ua kom cov txheej txheem kom qhuav.
Bitumen kua roj vanish hauv kev tsim
Qhov cuam tshuam ntawm kev laus -ib tug txawv nthuav dav ntawm niaj hnub lub teb chaws tsev. Thiab nyob rau hauv no bituminous kua roj vanish ua raws li lub ntsiab pab. Nws yog siv rau qhov chaw nrog ib tug niaj hnub txhuam los yog nrog ib tug sprayer. Lub thinner cov khaubncaws sab nraud povtseg, qhov zoo dua qhov tshwm sim yuav. Thaum tsim cov nyhuv ntawm kev laus nyob rau sab saum toj ntawm cov kua roj vanish, nws raug nquahu kom siv lub shellac txheej. Raws li txoj cai, cov kua roj vanish bituminous yog siv los ua cov txheej txheem sab nraud - laj kab, ntaiv, laj kab. Nws yuav tsum nco ntsoov tias nws tsis tuaj yeem siv cov khoom no ze ntawm qhov hluav taws kub.
Bitumen kua roj vanish hnub no ncaj ncees rov qab los rau nws txoj haujlwm tseem ceeb ntawm nws cov yeeb yaj kiab.
Pom zoo:
Dab tsi yog qhov txawv ntawm cov roj sunflower uas tsis muaj roj thiab lwm cov roj zaub
Unrefined sunflower roj tuaj yeem tshem tawm cov khoom tsis zoo los ntawm kev siv tshuab yooj yim - kev teeb tsa, centrifugation thiab pom. Qhov no kuj yog refining, tab sis thaum nws ua tiav, cov ntsiab lus ntawm cov as-ham thiab vitamins tsis txo qis
Xim thiab kua roj vanish: hom, qhov sib txawv, khoom thiab piav qhia
Cov xim thiab cov kua roj vanish tseem yog ib qho kev nyiam tshaj plaws rau kev kho kom zoo nkauj sab hauv thiab sab nrauv ntawm ntau yam qauv. Ntxiv mus, cov cheeb tsam ntawm daim ntawv thov ntawm cov khoom no txuas ntxiv nthuav dav, uas tau lees paub los ntawm kev hloov kho tshiab tiv thaiv cov khoom sib txuas
Roj yog cov ntxhia. Cov roj deposits. Roj ntau lawm
Roj yog ib qho tseem ceeb tshaj plaws hauv ntiaj teb cov zaub mov (hydrocarbon roj). Nws yog cov khoom siv raw rau kev tsim cov roj, lubricants thiab lwm yam ntaub ntawv
Vim li cas ruble nyob ntawm cov roj thiab tsis yog roj lossis kub? Vim li cas tus nqi pauv ruble nyob ntawm tus nqi ntawm cov roj, tab sis tus nqi pauv nyiaj duas tsis?
Ntau tus hauv peb lub tebchaws xav paub yog vim li cas ruble nyob ntawm cov roj. Yog vim li cas yog tias tus nqi ntawm cov kub dub txo, tus nqi ntawm cov khoom txawv teb chaws nce, nws nyuaj dua kom tau tawm mus so rau txawv teb chaws? Nyob rau tib lub sij hawm, lub teb chaws txiaj yuav tsis tshua muaj nqis, thiab nrog nws, tag nrho cov kev txuag
Vuam hauv qhov chaw tiv thaiv roj: ua haujlwm thev naus laus zis, txheej txheem piav qhia, cov txheej txheem ua tiav, cov khoom tsim nyog thiab cov cuab yeej, cov lus qhia ua haujlwm ib ntus thiab cov lus qhia kws tshaj lij
Vuam thev naus laus zis yog siv hauv ntau ceg ntawm tib neeg kev ua haujlwm. Versatility tau ua vuam nyob rau hauv ib puag ncig tiv thaiv roj ib qho tseem ceeb ntawm kev tsim khoom. Qhov ntau yam no ua rau nws yooj yim los txuas cov hlau nrog lub thickness ntawm 1 hli mus rau ob peb centimeters nyob rau hauv txhua txoj hauj lwm nyob rau hauv qhov chaw. Vuam nyob rau hauv ib puag ncig tiv thaiv yog maj mam hloov cov tsoos electrode vuam
