Uphethiloli B-70. Uphethiloli wendiza wekhulu leminyaka elidlule

Izici zokwakheka kanye nezakhiwo

Uphethiloli B-70 ubonakala ngokuthi:

• Ukungabi khona kwe-additive tetraethyl lead, okwenza kuphephe ngangokunokwenzeka emvelweni.
• Inkomba yenombolo ye-octane, esiza inqubo yokuthungela ngempoqo.
• Ubuthi obuncane be-vapors, obungadingi ukudalwa kwezinyathelo ezikhethekile, ezibiza kakhulu zokugcinwa kwayo okuphephile.

Ukwakheka kukaphethiloli kuhlanganisa ama-hydrocarbon agcwele kanye nama-isomer awo, i-benzene nemikhiqizo yokucubungula kwawo, kanye nezinhlanganisela ze-alkyl ezinuka kamnandi. Inani elincane le-sulfure ne-resinous substances livunyelwe, elingadluli i-2,1% isiyonke.

Izakhiwo eziyinhloko ze-aviation petroli brand B-70:

1. Ukuminyana, kg/m³ ekamelweni lokushisa: 750.
2. Izinga lokushisa lokuqala kwenqubo ye-crystallization, ⁰C, hhayi ngaphansi: -60.
3. Inombolo ye-octane: 70.
4. Ukucindezela komhwamuko ogcwele, kPa: 50.
5. Ubude besikhathi sokugcina ngaphandle kokuncipha, h, hhayi ngaphansi: 8.
6. Umbala, iphunga - akukho.

Sebenzisa

Uphethiloli B-70 wadalelwa ukusetshenziswa eyinhloko piston izindiza izinjini. Njengamanje, isabelo sokusetshenziswa okungokoqobo kwendiza ye-piston kwezokuthutha sehle kakhulu. Ngakho-ke, uphethiloli okhiqizwayo usetshenziswa kakhulu njenge-solvent yendawo yonke, lokhu kuqhutshwa yizimfanelo ezilandelayo:

• Ihwamuka ngokushesha kunoma iyiphi indawo, ingashiyi namabala kuyo.
• Ukuncika okuphansi ekushintsheni kwezinga lokushisa, okuhlala ngisho nasemazingeni okushisa amabi omoya wangaphandle.
• I-Homogeneity yokwakheka kwamakhemikhali, okuvumela ukugcina isikhathi eside (kuncike ezingeni lokushisa elidingekayo, umswakama ohambelana nomoya omuhle.

Ama-GOST akhona kaphethiloli wendiza anesibopho esikhulu samaphethiloli, aqukethe izithasiselo zokulwa nokungqongqoza. Lokhu akusebenzi kuphethiloli we-B-70, futhi ukusebenza kwawo kwemvelo kuphakeme kakhulu kunophethiloli wendiza wezinye izinhlobo.

Ubuchwepheshe bokusebenzisa uphethiloli B-70 njenge-solvent

Ngazo zonke izimfanelo zayo ezinhle, uphethiloli wendiza njenge-solvent kusanconywa ukuthi usetshenziswe ngokucophelela. Isizathu salokhu kubhekwa njengokuncipha ngokweqile komswakama wesikhumba, ukungena ngokuphelele kwezingxenye zaleli phethiloli ezithweni zangaphakathi. Ngakho-ke kunconywa ukusetshenziswa kwamagilavu ​​enjoloba angamelana ne-asidi. Isici esibalulekile esinqunyelwe ukuba khona kwezithasiselo zokulwa neqhwa kuphethiloli, okusebenza njenge-mutagen.

Ukusetshenziswa kukaphethiloli we-B-70 wokuhlanza ukungcola okunamafutha kuyazithethelela kuphela lapho kusebenza namayunithi okusebenza okunzima ukufinyelela kuwo, lapho ukuguquguquka okuphezulu kukaphethiloli wendiza kusiza ukuyiletha ngokushesha kunoma iyiphi indawo. Ukusebenza kwe-solvent kuyanda uma i-viscosity yefilimu yamafutha ezosuswa ebusweni iyancipha. Kuye kwatholakala ukuthi, uma kuqhathaniswa nophethiloli wokusetshenziswa okufanayo (isibonelo, uphethiloli we-Kalos, noma esikhundleni sika-Kallos, ngemva kukasokhemisi waseHungary owahlongoza okokuqala lokhu kwakheka ukuze kusetshenziswe njengesixazululi), i-B-70 ihlakaza ukungcola kwe-organic futhi idinga okumbalwa. Imikhawulo yokungena komoya izakhiwo lapho umsebenzi onjalo wenziwa khona.

Inani ngethani

Izintengo zale mikhiqizo azinzile kakhulu, ngakho-ke abahlinzeki abaningi bakhetha ukusebenza emakethe ngenani lentengo okuxoxiwe ngalo. Kodwa, kunoma yikuphi, intengo incike kumthamo wokuthengiselana kanye nokukhetha kwemikhiqizo yokupakisha:

• Ukupakisha esitsheni esinomthamo we-1 litre - kusuka kuma-ruble ayi-160.
• Ukupakisha emiphongolweni engama-200 l - ama-ruble ayi-6000.
• Kubathengi abakhulu - kusuka kuma-ruble angama-70000 ngethani.
