Lavxias teb sab cov neeg siv khoom tsis muaj cov pa roj carbon ntawv reels los ntawm Eurasia av choj railway thauj
Carbon dawb carbon ntawv yog ib yam ntawm cov ntawv zais cov pa roj carbon monoxide, nrog cov pa roj carbon monoxide ncaj qha, cov xim ncaj qha ua haujlwm. Nws txoj kev loj hlob xim yog tsuas yog: nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, lub zog ntawm phytochrome thiab roj tov nyob rau hauv lub microcapsule overflow thiab chromogenic tus neeg sawv cev tiv tauj tom qab dyeing cov tshuaj tiv thaiv, thiaj li mus ua si lub luag hauj lwm ntawm carbon daim ntawv. Feem ntau yog siv rau ntau daim ntawv, cov nqi, cov nqi nyiaj txiag tsis tu ncua, cov nqi lag luam nyiaj txiag dav dav thiab lwm yam.
Cov pa roj carbon COPY TSIS TXAUS SIAB "carbon paper", sau ncaj qha yooj yim txuag lub sijhawm, carbon luam ntawv txuas 2-6 nplooj ntawv, hluav taws xob luam ntawv 2-10 nplooj ntawv, tuaj yeem txhim kho kev ua haujlwm zoo, kom ua tau raws li qhov xav tau ntawm kev hloov kho tshiab.
Luam cov ntawv sau kom meej, ci, tsis ploj, tuaj yeem tiv thaiv kev hloov pauv, imitation.
Tsis txhob kis tus ntiv tes, khaub ncaws thiab lwm yam ntawv sau, ua kom huv si.
Nrog ntau yam xim, yooj yim los txheeb xyuas cov txheej txheem.
Cov ntawv zoo, du nto, tshaj 28 grams ntawm cov ntawv xim muaj zog, tsis yooj yim rau kev puas tsuaj, muaj yeeb yuj luam ntawv.
Tsis muaj teeb meem raw cov ntaub ntawv thiab cov ntxhiab tsw ntxhiab, muaj kev nyab xeeb thiab txhim khu kev qha, cov ntawv thiab cov ntawv tuaj yeem khaws cia rau ntau tshaj 15 xyoo tom qab tsim xim.
Cov neeg siv khoom Lavxias tau xaj peb lub thawv loj ntawm cov ntawv tsis muaj cov pa roj carbon monoxide los ntawm IPRO-DVA, uas yuav raug xa mus rau cov neeg siv khoom ntawm Eurasian Continental Choj railway tsheb thauj mus los.
