Kodi ndiyenera kugwiritsa ntchito mafuta amoto okhala ndi molybdenum?

Pali ndemanga zabwino komanso zoyipa zamafuta agalimoto okhala ndi molybdenum. Ena amakhulupirira kuti chowonjezera ichi chimapatsa mafuta makhalidwe abwino. Ena amati molybdenum imawononga injini. Enanso amakhulupirira kuti kutchulidwa kwa chitsulo ichi m'magulu a mafuta ndi njira yotsatsa malonda ndipo mafuta omwe ali nawo sali osiyana ndi ena onse.

Zomwe molybdenum amagwiritsidwa ntchito mumafuta agalimoto

Ndikofunika kudziwa kuti molybdenum yoyera sinagwiritsidwepo ntchito mumafuta. Molybdenum disulfide (molybdenite) yokha ndi yomwe imagwiritsidwa ntchito ndi mankhwala a MOS2 - atomu imodzi ya molybdenum yolumikizidwa ku maatomu awiri a sulfure. Mu mawonekedwe enieni, ndi ufa wakuda, woterera pokhudza, ngati graphite. Amasiya chizindikiro papepala. "Mafuta okhala ndi molybdenum" ndi mawu omwe amagwiritsidwa ntchito kwambiri pamoyo watsiku ndi tsiku, kuti asasokoneze kulankhula ndi mawu a mankhwala.

Tinthu tating'onoting'ono ta molybdenite tili ngati ma flakes ang'onoang'ono okhala ndi mafuta apadera. Zikagundana, zimatsetsereka, zomwe zimachepetsa kwambiri kukangana.

Kodi ubwino wa molybdenum ndi chiyani?

Molybdenite imapanga filimu pazigawo zowonongeka za injini, nthawi zina zokhala ndi mitundu yambiri, zimawateteza kuti asavale ndipo amagwira ntchito ngati wothandizira.

Kuwonjezera pa mafuta a galimoto kumapereka ubwino wambiri:

• mwa kuchepetsa kukangana, kugwiritsa ntchito mafuta kumachepetsedwa kwambiri;
• injini imayenda mofewa komanso mwabata;
• ikagwiritsidwa ntchito ndi mafuta owoneka bwino kwambiri, chowonjezera ichi chikhoza, kwakanthawi kochepa, koma kukulitsa moyo wa injini yotopa musanasinthe.

Zodabwitsa izi za molybdenite zidapezeka ndi asayansi ndi zimango mu theka loyamba la zaka za zana la 20. Kale mu Nkhondo Yachiwiri Yapadziko Lonse, chowonjezera ichi chinagwiritsidwa ntchito pa zida zankhondo za Wehrmacht. Chifukwa cha filimu ya molybdenite pazigawo zovuta zowonongeka za injini, mwachitsanzo, thankiyo imatha kusuntha kwa nthawi ndithu ngakhale itataya mafuta. Chigawochi chidagwiritsidwanso ntchito mu ma helikoputala ankhondo aku US, komanso m'malo ena ambiri.

Pamene Molybdenum Itha Kukhala Yowopsa

Ngati chowonjezera ichi chinali ndi ma pluses okha, ndiye kuti sipakanakhala chifukwa cholankhula za mfundo zoipa. Komabe, pali zifukwa zotere.

Molybdenum, kuphatikizapo disulfide, amayamba oxidize pa kutentha pamwamba 400C. Pankhaniyi, mamolekyu a okosijeni amawonjezeredwa ku mamolekyu a sulfure, ndipo zinthu zatsopano zokhala ndi zinthu zosiyanasiyana zimapangidwa.

Mwachitsanzo, pamaso pa mamolekyu amadzi, sulfuric acid imatha kupangidwa, yomwe imawononga zitsulo. Popanda madzi, mankhwala a carbide amapangidwa, omwe sangayikidwe pazigawo zosisita nthawi zonse, koma amatha kuyikidwa m'malo ongokhala a gulu la pistoni. Zotsatira zake, kupaka mphete za pistoni, kuwombera galasi la pistoni, kupanga slag komanso kulephera kwa injini kungathe kuchitika.

Izi zimathandizidwa ndi kafukufuku wasayansi:

• Kugwiritsa ntchito TEOST MHT kuti Muyese Oxidation Yofunika Kwambiri mu Mafuta Otsika a Phosphorus Engine (STLE);
• Kusanthula kwa Deposit Formation Mechanism pa TEOST 33 C ndi Engine Mafuta Okhala ndi Mo DTC;
• Kupititsa patsogolo Chuma cha Mafuta ndi MoDTC popanda Kuchulukitsa TEOST33C Deposit.

Chifukwa cha maphunzirowa, zatsimikiziridwa kuti molybdenum disulfide, pansi pazifukwa zina, amagwira ntchito monga chothandizira kupanga ma carbide deposits.

Chifukwa chake, mafuta okhala ndi chowonjezera chotere sakuvomerezedwa kuti agwiritsidwe ntchito mu injini pomwe kutentha kwa ntchito m'dera la wiritsa kumakhala pamwamba pa madigiri 400.

Opanga amadziwa bwino za injini zawo. Chifukwa chake, amapereka malingaliro pazomwe mafuta ayenera kugwiritsidwa ntchito. Ngati pali kuletsa kugwiritsa ntchito mafuta okhala ndi zowonjezera zotere, ndiye kuti sayenera kugwiritsidwa ntchito.

Komanso, mafuta amenewa akhoza kuimba ntchito zoipa pa injini iliyonse pamene kutenthedwa pamwamba 400C.

Molybdenite ndi chinthu chosagwirizana ndi kupsinjika kwamakina. Osakonda kuzimiririka ndi kuzimiririka. Komabe, mafuta a molybdenum sayenera kuthamangitsidwa kupitirira mtunda wovomerezeka wa wopanga chifukwa chachikulu m'munsi katundu ndi zina zowonjezera zingakhale vuto.

Momwe mungadziwire kukhalapo kwa molybdenum mumafuta a injini

Pokhala ndi mpikisano wowopsa pamsika wamafuta agalimoto, palibe wopanga angawononge bizinesi yake powonjezera zowonjezera zovulaza kumafuta. Komanso, palibe wopanga adzawulula kapangidwe ka mafuta awo mokwanira, chifukwa ichi ndi chinsinsi chachikulu cha mafakitale. Choncho, n'zotheka kuti molybdenite ilipo mosiyanasiyana mumafuta ochokera kwa opanga osiyanasiyana.

Wogula wosavuta sayenera kutenga mafutawo kupita ku labotale kuti azindikire kukhalapo kwa molybdenum. Kwa inu nokha, kukhalapo kwake kungadziwike ndi mtundu wa mafuta. Molybdenite ndi imvi yakuda kapena ufa wakuda ndipo imapatsa mafutawo mdima wakuda.

Kuyambira nthawi ya USSR, gwero la injini magalimoto chawonjezeka kangapo. Ndipo kuyenera mwa izi sikuti ndi opanga okha, komanso opanga mafuta amakono. Kuyanjana kwa mafuta okhala ndi zowonjezera zosiyanasiyana ndi zida zamagalimoto kumaphunziridwa m'lingaliro lenileni pamlingo wa ma atomu. Wopanga aliyense amayesetsa kukhala wabwino kwambiri pakulimbana kolimba kwa wogula. Nyimbo zatsopano zikupangidwa. Mwachitsanzo, m'malo mwa molybdenum, tungsten disulfide amagwiritsidwa ntchito. Chifukwa chake, mawu okopa "Molybdenum" ndi njira yotsatsa yopanda vuto. Ndipo ntchito ya wokonda galimoto ndi kugula mafuta oyambirira (osati abodza) kuchokera kwa opanga ovomerezeka.
