** Ceeb Toom Tseem Ceeb:** Qhov no yog cov ntaub ntawv keeb kwm archive, tsis yog ib qho kev pom zoo tam sim no, kev ntsuam xyuas kev pheej hmoo lossis kev qhia txog kev ziab ntoo hauv rhuab petrolatum. Kub, tso tsheb hlau luam, cua sov, qhov cua, nqa, roj av, emissions, hluav taws kub thiab tawg tiv thaiv, neeg ua hauj lwm kev noj qab haus huv thiab ib puag ncig tiv thaiv yuav tsum tau soj ntsuam raws li cov kev cai tam sim no thiab los ntawm cov kws txawj tso cai.
Cov ntawv no tsis yog kev muab petrolatum, tshuab ziab khaub ncaws lossis tsim cov nroj tsuag zoo li no los ntawm Savo Kusić. Qhov kev thov tam sim no yog tsom rau ntawm qhov rais, qhov rooj thiab cov kev daws teeb meem cuam tshuam.
Cov ntaub ntawv keeb kwm thiab txheej txheem
Hauv kev lag luam ntoo ntawm kev tsim kho kev lag luam, ziab ntawm sawn ntoo kuj tseem siv hauv petrolatum. Petrolatum yog ib qho pov tseg tau txais thaum lub sij hawm ua cov roj av rau lubrication.
Nws yog ib tug sib tov ntawm paraffin, ceresin thiab purified viscous roj. Ntawm qhov kub thiab txias20o petrolatum muaj xim daj-daj. Nws lub ntiajteb txawj nqus yog approx0.9, melting kub250o, curing kub50o. Kev siv petrolatum rau ziab 1mconiferous ntoo xws li los ntawm20rau25 kg. Tus nqi ntawm kev ziab kom qhuav yog qis dua tus nqi ntawm kev ziab hauv chav ziab khaub ncaws.

Cov cuab yeej siv keeb kwm
Kev tsim cov roj av tshuab ziab khaub ncaws (Fig1) yog yooj yim heev. Nws muaj ib lub tank steel embedded nyob rau hauv ib tug pob zeb qhov chaw thiab lined nrog slag ntaub plaub rau thermal rwb thaiv tsev. Nyob rau hauv qab ntawm lub tank, muaj cov kav dej rau cov cua sov petrolatum, uas cov pa los yog pa pa nkag mus. Cov ntoo sawn tau muab tso rau hauv cov thawv tshwj xeeb, uas tau txo qis rau hauv lub tank nrog rhuab petrolatum siv lub tshuab hluav taws xob.
keeb kwm kub thiab ntev
Lub sijhawm ziab yog nyob ntawm qhov kub thiab txias, uas rau cov ntaub ntawv nyias nyias tuaj yeem ncav cuag i140oh, thiab rau cov rog tshaj plaws110o. Raws li cov ntaub ntawv, sawn ntoo los ntawm coniferous ntoo yog tuab25 mmlos ntawm av noo45%rau av noo15%nws dries rau3h,a tuab40-45 mm- rau8h. Sectional txaj100x100 mmlawv qhuav rau22-24h, uas yog kwv yees15-20sij hawm sai dua li ziab hauv chav chav.
Tom qab ziab, cov khoom yuav tsum tau khaws cia hauv chav txias lossis hauv lub tsev rau khoom rau ob mus rau peb hnub, tom qab ntawd nws tuaj yeem ua tiav ntawm cov tshuab.
Cov lus piav qhia keeb kwm ntawm qhov zoo thiab kev txwv
Lub ziab zoo ntawm coniferous thiab coarsely ntxeem tau ntoo yog txaus siab kiag li. Oak ntoo thiab ntoo ntawm conifer hom ntawm cov ntoo khaub lig-section loj thaum qhuav hauv petrolatum muab ib tug ntau npaum li cas ntawm seem vim yog tsim ntawm sab hauv tawg. Petrolatum nkag mus rau hauv cov ntoo, uas dries mus rau ib tug tob ntawm2 mm; Nrog rau qhov no, ntoo yog antisepticized, tab sis petrolatum crust, uas yog tsim thaum lub sij hawm tus txheej txheem no, ua rau nws nyuaj rau txheej txheem ntoo nrog tshuab. Nyob rau hauv tas li ntawd, nyob rau hauv qhuav sawn ntoo, ib tug unevenly faib ntawm noo noo yuav pom nyob rau hauv lub seem, uas, nyob ntawm seb hom ntoo, ntau yam6rau14%.
