5. Inactive Rau Lubricating Roj
Lub tub yees yuav tsum tsis txhob hnov qab nrog cov roj lubricating thiab yooj yim sib cais. Hom khoom siv tub yees no yog suav tias yog cov chav kawm zoo tshaj plaws. Cov cuab yeej no muaj nyob hauv ammonia.
6. Tsawg toxicity
Cov tub yees yuav tsum tsis txhob muaj tshuaj lom. Yog tias nws muaj tshuaj lom, cov dej xau ntawm cov khoom siv tub yees los ntawm lub kaw lus yuav tsum tau yooj yim tshawb pom kom tsis txhob muaj kev puas tsuaj los ntawm kev kaw qhov xau sai.
7. Corrosiveness Ntawm Hlau
Cov hlau tub yees yuav tsum tsis txhob smelted. Ntawd yog, tsis txhob hnov qab yaig nrog hlau. Yog hais tias lub tub yees ua erosion ntawm cov ducts siv, nws yuav hlawv los yog strangulate los yog tho lawv. Yog li ntawd, lawv yuav tsum tau hloov sai sai. Yog li ntawd, tus nqi khiav ntawm cov nroj tsuag yuav nce.
8. Cov tub yees yuav tsum tsis yog-inflammable thiab tsis-explosive
Cov tub yees siv yuav tsum tsis txhob tua hluav taws thiab tawg kom nws muaj kev nyab xeeb siv. Muaj kev puas tsuaj ntau dua yog tias cov tub yees yog cov nplaim taws thiab tawg.
9. Tsawg viscosity
Qhov tsawg gluten nyob rau hauv lub tub yees ua rau nws yooj yim dua ntws los ntawm cov kav dej, txhais tau hais tias cov viscosity tsawg dua uas cov tub yees tuaj yeem yooj yim txav mus rau hauv cov raj.
10. Tus nqi qis
Lub tub yees yuav tsum yooj yim muaj thiab tus nqi qis.
Ua rau Depletion ntawm Ozone Txheej
Lub depletion ntawm ozone txheej yog ib qho kev txhawj xeeb loj thiab cuam tshuam nrog ntau yam. Lub ntsiab yog vim li cas lub luag hauj lwm rau depletion ntawm ozone txheej yog teev hauv qab no:
Chlorofluorocarbons
Chlorofluorocarbons los yog CFCs yog lub ntsiab ua rau depletion ntawm ozone txheej. Cov no yog muab los ntawm xab npum, kuab tshuaj, tshuaj tsuag aerosols, tub yees, cua txias, thiab lwm yam.
Molecules ntawm chlorofluorocarbons nyob rau hauv lub stratosphere yog tawg los ntawm ultraviolet hluav taws xob thiab tso chlorine atoms. Cov atoms hnov mob nrog ozone thiab rhuav tshem nws.
Irregular Rocket Launch
Kev tshawb fawb hais tias qhov tsis zoo ntawm lub foob pob hluav taws ua rau muaj kev puas tsuaj ntau dua ntawm ozone txheej dua li CFC. Yog tias qhov no tsis tswj hwm, los ntawm xyoo 2050, txheej txheej ozone yuav raug kev puas tsuaj loj.
Nitrogenous compounds
Nitrogenous tebchaw xws li NO2, NO, thiab N2O yog lub luag haujlwm rau kev degradation ntawm ozone txheej.
Vim li cas
Cov txheej txheej ozone tsis zoo rau qee yam txheej txheem xws li hnub ci me ntsis thiab cua stratospheric. Tab sis qhov no ua rau cov txheej ozone txo qis dua 1-2%.
Ozone Depletion Khoom
Ozone-depleting tshuaj yog cov khoom xws li chlorofluorocarbons, halons, carbon tetrachloride, hydrofluorocarbons, thiab lwm yam, uas yog lub luag hauj lwm rau kev lwj ntawm ozone txheej.
Cov Lus Kawg: Ntau Hom Tub Txias
Yog tias koj yog ib tus neeg mob siab txog kev siv hluav taws xob thiab ib puag ncig, xaiv lub tshuab cua txias nrog R-290 lossis lub tub yees nrog R-600A. Qhov ntau koj txiav txim siab rau nws, ntau lub tuam txhab yuav pib siv lawv hauv lawv cov khoom siv.
Lus Cim:
Qee cov ntawv tau muab los ntawm Is Taws Nem. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm. Yog tias koj txaus siab rau cov khoom siv twj tso kua mis, thov hu rau OSB lub tuam txhab kub twj tso kua mis, peb yog koj qhov kev xaiv zoo tshaj.
