Isesengura ry'ubushyuhe buke n'ubushyuhe bwinshi bw'ibice by'amavuta byasizweho amavuta

Gusiga amavuta muri rusange bikwiriye gukoreshwa ku muvuduko muto kugeza kuri hagati aho ubushyuhe bw'imikorere y'amavuta buri munsi y'ubushyuhe ntarengwa bwa amavuta. Nta mavuta yo kurwanya friction akwiriye gukoreshwa muri byose. Buri mavuta afite imikorere n'imiterere bike gusa. Amavuta agizwe n'amavuta y'ibanze, ubwinshi n'inyongera. Amavuta yo gutera amavuta akenshi aba arimo amavuta y'ibanze ya peteroli yakuwemo isabune y'icyuma runaka. Mu myaka ya vuba aha, amavuta y'umwimerere n'ay'umwimerere yongewemo amavuta y'ibanze. Imbonerahamwe ya 26 igaragaza muri make imiterere y'amavuta asanzwe. Imbonerahamwe ya 26. Ibikoresho bya Grease Base Oil Thickener Additive Grease Mineral Oil Synthetic Hydrocarbon Ester Substance Perfluorinated Oil Silicone Lithium, Aluminium, Barium, Calcium na Compound Sabuni Uduce duto (inorganic) Kole (ibumba), umukara wa karuboni, silica gel, PTFE sabuni-idafite (organic) polyurea compound rust inhibitor dye tackifier metal passivator antioxidant anti-wear extreme pressure additive based calcium and aluminium-based greases are well anti-water, akoreshwa mu nganda zigomba gukumira ubushuhe. Amavuta akozwe muri Lithium afite akamaro kenshi kandi akwiriye gukoreshwa mu nganda no mu mapine y’ibiziga.
Amavuta y’ibanze ya sintetike, nka esters, esters organic na silicones, iyo akoreshejwe hamwe n’ibinini bikoreshwa cyane n’inyongeramusaruro, ubushyuhe ntarengwa bwo gukora bukunze kuba buri hejuru y’ubushyuhe ntarengwa bwo gukora bw’amavuta akomoka kuri peteroli. Ubushyuhe bwo gukora bw’amavuta ya sintetike bushobora kuba hagati ya -73°C na 288°C. Ibi bikurikira ni ibiranga ibinini bikoreshwa cyane n’amavuta akomoka kuri peteroli. Imbonerahamwe ya 27. Ibiranga rusange by’ibinini bikoreshwa mu mavuta akomoka kuri peteroli Ibinini binini bikoreshwa ahantu hatandukanye Ubushyuhe ntarengwa bwo kugabanuka kw’amazi Ukoresheje ibinini biri mu mbonerahamwe ya 27 hamwe n’amavuta ya sintetike ya hydrocarbon cyangwa ester, ubushyuhe ntarengwa bwo gukora bushobora kugerwaho Bwongereho hafi 10°C.

Gukoresha polyurea nk'umuti wongera imbaraga ni kimwe mu bintu by'ingenzi byateye imbere mu bijyanye no gusiga amavuta mu gihe cy'imyaka irenga 30. Amavuta ya polyurea agaragaza imikorere myiza mu buryo butandukanye bwo gusiga amavuta, kandi mu gihe gito, yamenyekanye nk'umuti ukoreshwa mu gutera amavuta mbere yo kuyasiga. Ubushyuhe buke Mu gihe cy'ubushyuhe buke, imbaraga zo gutangira za mavuta zirimo amavuta ni ingenzi cyane. Amavuta amwe ashobora gukora neza gusa iyo mavuta arimo gukora, ariko azatuma adashobora gutangira neza. Mu mashini zimwe na zimwe nto, ashobora kudatangira iyo ubushyuhe buri hasi cyane. Muri ubwo buryo bwo gukora, bisaba ko mavuta agira imiterere y'ubushyuhe buke bwo gutangira. Niba ubushyuhe bwo gukora ari bunini, amavuta y'ubukorikori afite ibyiza bigaragara. Amavuta ashobora gutuma imbaraga zo gutangira no gukora ziba nto cyane ku bushyuhe buke bwa -73°C. Hari igihe, aya mavuta akora neza kurusha amavuta muri uru rwego. Ingingo y'ingenzi ku mavuta ni uko imbaraga zo gutangira atari ngombwa ko ari uguhuza kw'amavuta cyangwa imikorere rusange. Imbaraga zo gutangira zimeze nk'imikorere y'amavuta runaka, kandi bigenwa n'uburambe.
Ubushyuhe bwinshi: Ubushyuhe bwinshi bw'amavuta agezweho akenshi buterwa n'uburyo amavuta y'ibanze agumana ubushyuhe n'ubushobozi bwo kurwanya ogisijeni. Ubushyuhe bw'amavuta bugenwa n'aho amavuta y'ibanze amanuka n'imiterere y'amavuta y'ibanze. Imbonerahamwe ya 28 igaragaza ubushyuhe bw'amavuta mu bihe bitandukanye by'amavuta y'ibanze. Nyuma y'imyaka myinshi y'igerageza ku mavuta asize amavuta, uburyo bwayo bwo gupima bugaragaza ko ubuzima bw'amavuta azagabanukaho kimwe cya kabiri kuri buri 10°C mu bushyuhe bwiyongereye. Urugero, niba ubuzima bw'amavuta ku bushyuhe bwa 90°C ari amasaha 2000, iyo ubushyuhe buzamutse bukagera kuri 100°C, ubuzima bw'amavuta buragabanuka bukagera ku masaha agera ku 1000. Ku rundi ruhande, nyuma yo kugabanya ubushyuhe bukagera kuri 80°C, ubuzima bw'amavuta buteganijwe kugera ku masaha 4000.
