Ciatim-221. Makhalidwe ndi ntchito

makhalidwe a

Mafuta a Ciatim-221 amapangidwa malinga ndi luso la GOST 9433-80. M'malo ake oyamba, ndimadzimadzi owoneka bwino ozikidwa pa organosilicon, pomwe sopo zachitsulo zolemera kwambiri zimawonjezedwa kuti zithandizire kusasinthika. The chomaliza mankhwala ndi homogeneous kuwala bulauni mafuta. Pofuna kuchepetsa oxidizability panthawi yolumikizana ndi mechanochemical yomwe imayamba pa kutentha kwakukulu, zowonjezera zowonjezera za antioxidant zimaphatikizidwa muzopangira mafuta.

Zigawo zazikulu zamafuta awa molingana ndi GOST 9433-80 ndi:

1. Dynamic viscosity, Pa s, pa -50^°C, osapitirira 800.
2. kutentha koyambira kwa dontho, ^°C, osachepera -200.
3. Analimbikitsa ntchito kutentha osiyanasiyana - kuchokera -50^°C mpaka 100^°C (wopanga amati mpaka 150^°C, koma ogwiritsa ntchito ambiri samatsimikizira izi).
4. Kupsyinjika kwakukulu kumasungidwa (kutentha kwa firiji) ndi gawo lopaka mafuta la makulidwe oyenera, Pa - 450.
5. Kukhazikika kwa Colloidal,% - osapitirira 7.
6. Nambala ya Acid malinga ndi NaOH, osapitirira 0,08.

Zonyansa zamakina ndi madzi mumafuta opaka mafuta amayenera kulibe. Pambuyo kuzizira, katundu wa mankhwala amabwezeretsedwa bwino.

Kodi chimagwiritsidwa ntchito ndi chiyani?

Monga omwe adawatsogolera - mafuta a Ciatim-201 - mankhwalawa amagwiritsidwa ntchito kuteteza malo opaka otsika kwambiri a zida zamakina kuti asavale movutikira, omwe amatsagana ndi makutidwe ndi okosijeni. Kuti izi zitheke, ndikofunikira nthawi zonse kuonetsetsa kuti makulidwe okwanira amafuta opaka mafuta, omwe sayenera kukhala osachepera 0,1 ... 0,2 mm. Pachifukwa ichi, kutsika kwapang'onopang'ono mu wosanjikiza nthawi zambiri kumakhala mpaka 10 Pa / μm.

Zinthu zotere ndizofanana ndi zida zosiyanasiyana - makina aulimi, makina odulira zitsulo, magalimoto, zida zonyamula zida zogwirira ntchito, etc. Chifukwa cha kukana kwambiri kwa dzimbiri, mafuta ofotokozedwawa amagwiritsidwa ntchito mosavuta pamakina omwe akugwira ntchito m'mikhalidwe ya chinyezi chachikulu.

Ubwino wa lubricant wa Ciatim-221:

• mankhwala amasungidwa bwino pa malo okhudzana, ngakhale ndi makonzedwe awo ovuta;
• sichisintha katundu wake pakusintha kwadzidzidzi kutentha;
• kukana chisanu;
• kusayanjanitsika kwa mphira;
• chuma cha mowa, chomwe chimagwirizana ndi kusinthasintha kochepa kwa mankhwala.

Malinga ndi mawonekedwe a ogula, Ciatim-221 ndiyopambana kwambiri kuposa mafuta. Chifukwa chake, zinthu zomwe zikufunsidwa zimalimbikitsidwa kuti zisungidwe ma hydraulic accumulators, zida zowongolera zamagalimoto, ma jenereta, ma pampu, ma compressor, ma unit tensioning ndi magawo ena omwe amatha kupeza chinyezi nthawi zonse. Kusintha kwa mafuta awa ndi Ciatim-221f, yomwe ilinso ndi fluorine ndipo imasinthidwa ndi kutentha kwanthawi yayitali.

Zoletsa

Mafuta a Ciatim-221 sagwira ntchito ngati chidacho chikugwiritsidwa ntchito kwa nthawi yayitali pakutentha kwambiri. Tiyeneranso kunena kuti mankhwalawa, chifukwa cha kukhuthala kwakukulu, amathandizira kuwonjezeka kwa kukana kukhudzana (ndi 15 ... 20%). Chifukwa cha ichi ndi mphamvu zofooka zamagetsi zomwe Cyatim-221 amawonetsa pa kutentha kwakukulu. Pachifukwa chomwechi, mafuta savomerezedwa kuti agwiritsidwe ntchito popaka zida zamagetsi zamagetsi.

Litol kapena Ciatim. Chabwino nchiyani?

Litol-24 ndi girisi wopangidwa kuti achepetse kutentha komanso kukangana kwa mayunitsi okhala ndi malo olumikizana. Ichi ndichifukwa chake mapangidwe ake akuphatikizapo mapulasitiki osiyanasiyana omwe sali mu mafuta a Ciatim.

Kukhuthala kwamphamvu kwamafuta a Litol-24 kumapangitsa kuti zinthuzo zikhale zolimba kukana kuthamangitsidwa kuchokera pamalo otetezedwa. Chifukwa chake, Litol-24 imagwira ntchito pamakina okangana amakina omwe akugwira ntchito pamakanikizidwe apamwamba kuposa omwe amawonetsedwa muzochita za Ciatim-221.

Chinthu china cha Litol ndikutha kugwira ntchito m'malo a anaerobic komanso malo opanda kanthu, pomwe zopangira mafuta onse a mzere wa Ciatim alibe mphamvu.

Mafuta onsewa amakhala ndi kawopsedwe kochepa.

mtengo

Zimatengera kuyika kwazinthu. Mitundu yodziwika bwino yamafuta opaka mafuta ndi awa:

• Banks ndi mphamvu 0,8 makilogalamu. mtengo - kuchokera 900 rubles;
• Zitsulo zachitsulo zokhala ndi malita 10. mtengo - kuchokera 1600 rubles;
• Migolo 180 kg. Mtengo - kuchokera ku ma ruble 18000.
