The ho itšeha mokelikeli (setsidifatsi): tlhophiso, kopo

thulaganyou e Metalworking e ka tlhaho amanang le khohlano e matla ea hore le hlaha pakeng tsa workpiece le sesebelisoa sa. Sena se totobala ka ho khetheha ha ho retelehela le siloa sebetsa, ha sesebelisoa ke chesang ka ho fetisisa, a batang extrusion, phahameng-lebelo rocker lulisa. E matla khohlano thusa hore ho apara liaparo tsa pele ho nako ea sesebelisoa sa, le deformation polasetiki ea workpiece, ho fetoha thepa tsa tšepe le ka lebaka la ho overheating. Ho fokotsa lebotho la khohlano hloka e khethehileng ho itšeha mokelikeli (setsidifatsi) le fokotseha mocheso.

Di-parameter tlhophiso coolants

Kakaretso tlhophiso coolants phethahatsoa ka entsprechen 'maloa:

• Ka tšimoloho ea metsoako ena. Hatisa oli setsidifatsi, tseo li thehiloe oli oli e tala, phoofolo kapa mafura meroho.
• Ke tsela kopanye. Emulsol - e se felile sehlahiswa ka nako e telele bophelo raka, athe kapa emulsion botekgeniki, e hlophisitsoeng hang-hang pele ho ho sebedisa ba mamelisise ho ea ka GOST.
• Ka 'mele le ho phetha molao feela entsprechen - e tiileng e qamathelang, palo acid e, le halima ho ntlha. The bath bobeli etsa hore kopo ya oli setsidifatsi tsa tapa chesang.
• Ho ea ka ea tšimo kopo. Se hlahisa mefuta e sa tšoaneng ea coolants bakeng sa maemo a fapaneng tsa ho sebelisa mehaho ea kopo. Maiketsetso itšeha mokelikeli bakeng sa tshebetso polasetiki deformation, setsidifatsi bakeng lathes kapa mechine e siloa.

Classification tsa setsidifatsi sebopeho

Ka ho hlophisoa ha setsidifatsi ho khetholla mefuta e latelang:

• Oli - formulations tsa dikarolo tse di immiscible ka metsi. Base oli emulsion ke parafini, diminerale kapa oli oli e tala (60-95%). Ho ntlafatsa ho atleha ha-ba khahlanong le tsofaleng, khohlano, ts'enyeho ka sebopeho kenyeletsa additives tse fapa-fapaneng le inhibitors. Oli emulsion rua thepa babatsehang ethylene bottom. Sebediswa bakeng sa lirafshoa tse bonolo ka mekhoa e bonolo ho sebelisa mehaho.
• Matsoai - botlaaseng entseng ho tloha oli ke hydrogenation catalytic. Ho eketsa ho atleha ea additives kenyelleditswe tloha mafura, chloride, sebabole, phosphorus metsoako. o hlophisitsoeng tsena li sebelisoa mefuta e joalo tsa tšepe, tse kang: seha tšepe, aluminium, koporo, khoele, siloa mosebetsi alloyed steels.
• Metsi miscible - e tharollo ea metsi e thehiloeng oli matsoai. o hlophisitsoeng tsena na thepa babatsehang tsidifatso le tlaase toxicity, empa tshebetso tlaase ethylene bottom. Boholo - leseli 'me mosebetsi mahareng retelehela koporo le boronse, sila le ho cheka tsa mefuta eohle ea tšepe batho bao e seng ferrous, ho sila le ho otla ka litebele tšepe.
• Maiketsetso le semisynthetic - motsoako oa metsi, surfactants, metsi polymers qhibilihang ka har'a,-ba khahlanong le phophomang le additives antibacterial, inhibitors ts'enyeho. Ho eketsa lubricity ka o hlophisitsoeng a maiketsetso a ba boetse ba tsamaisoa antiwear additives.
• Emulsions - o hlophisitsoeng le concentrations phahameng ya likaroloana qhalakantsoeng. Fokotsa tekanyo ea ho apara liaparo tse sa lisebelisoa le thepa ka ho hoo e batlang e tshebetso yohle metalworking.

Sebopeho le mochine oa ketso ea setsidifatsi ho

Tshebediso atile ea coolants ka dithulaganyo lokisa tšepe e loketseng ho karohano e atlehang ea bokaholimo hohla tsa workpiece le sesebelisoa sa le ho fokotsa mocheso bona. The setsidifatsi atlehang ka ho fetisisa a ka kenyeletsa dikarolo tse latelang ka sebopeho lona:

• Motheong oa oli maiketsetso kapa mafura liphoofolo.
• Additives hore eketsa qhoaele frictional le tshebetso feteletseng khatello.
• Dikarolo, ho thibela delamination sebopeho nakong polokelo.
• Additives hore thibela ts'enyeho le timetso.
• Dikarolo, fokotsa phophomang le wetting tsa bokaholimo ka tšepe.

Tshebediso ya setsidifatsi

maro Metalworking li sebelisetsoa ho loetsa litsepe le pholile ka tšepe le sebaka sebetsa. Properties setsidifatsi lumelloa ho fokotsa khohlano ka libaka kalafo, ka tsela eo ho fokotsa qhoaele oa sesebelisoa sa, ho eketsa boleng sehlahisoa ke ho ntlafatsa matla a tshebetso le, e le lebaka leo, ka tlhahiso ka kakaretso.

Ka lebaka la thepa ea bona e ntle ethylene bottom tsa setsidifatsi le ho fokotsa matla a frictional pakeng holim workpiece le ho itšeha bohale ba sesebelisoa eo, khohlano e sehiloeng tšepe lera. Ba bang ba selogetsi botekgeniki na thepa lik'hemik'hale e ntšetsang pele ea fokotseha ha feela lebotho frictional, empa hape le ho itšeha le tshebetsong. Fetisisa setsidifatsi - surfactants le thepa phahameng adsorption. Ba khona ho theha e filimi tsitsitse holim'a tšepe, tseo haholo ho fokotsa khohlano. Ba bang ba khethehileng surfactant additives na ka tšepe "wedging" nka khato. O molelele o limolek'hule joalo additives oela microcracks ka holim'a tšepe, joaloka chesele e, ka tsela eo ho fokolisa tlamahano pakeng tsa likaroloana tsa boitsebiso boo. Kahoo, setsidifatsi "thusa" ho sesebelisoa sebetsa ho khaola lera le tsoang tšepe e le setsi.
