Coolants: Iimpawu kunye nohlaziyo

Ngaphandle kuzakuthothisa asikwazi eziqhutshwa processing metal kakhulu mihla. Kulo mzekelo, izinto ebuntsimbi ngokwabo, asetyenziswa ubuchule ingangafikeleli iimfuno ezisebenzayo ngaphandle arhente inkonzo ekhethekileyo. Ukuza kuthi ga ngoku, ulwelo yokusika (njengesipholisi) ziya kuthengiswa kumagama ezingaphezu kwama-600. Phakathi kwabo siyakwazi ukufumana imali eza kusetyenziswa iiyunithi ngamandla ukuze zisetyenziswe processing metal, kwakunye zonyango, ubushushu, formorazdelyayuschie, ioli eziphilayo kunye anti-mhlwa. Inkoliso yezi ezilulwelo ezisetyenziswa kushishino kunye noshishino lokwakha.

Yintoni ulwelo ngensimbi?

Xa izithambiso ezininzi kuqaliswa kwi indawo yokusebenzela phakathi kwezakhi zochuku ukwenzela ukunciphisa banxibe le ndlela. Amaxesha amaninzi lo msebenzi zincediswe kukwanda eyiyo. Kodwa usebenza ngezixhobo zemveli hlobo, Noko ke, izinto okupholisa zikwafuneka ukukhusela izixhobo kunye nezinto zokusebenza ukusuka nobushushu. Ngokomzekelo, izinto zokuthambisa ukupholisa ukuba ngensimbi ukuvumela ukwandisa lobushushu kunye noxinzelelo ukuba ahlale phezulu. Ezifana imbuyekezo ngenxa yoko, ingabi kuphela ikuvumela ukugcina ukusebenza abaqingqi, kodwa ukuphucula indlela abaqhuba ngayo amanqaku onesiphumo. Kukho iindlela zokukhusela ezikhethekileyo apho kugxininiswa ekuboneleleni ngokudleka, zokwambathisa uphawu kwiipropati. Olu didi umbandela iqhelekileyo zokwakha.

coolants

Nayiphi igrisi senziwa iresiphi okhethekileyo. Kukho abhalwa ezisisiseko zolawulo, kwakunye uguqulelo, ezo bakulungele ukunika yokusebenza ethile. Amaninzi, isiseko ikhonza umxube oyile iphantsi-viscosity. Iveliswe ngoko coolants, apho ukwakhiwa kwakhona modified iparafini ikhlorini, dialkyldithiophosphates zinc, mnogozolnym calcium sulfonate, kunye nezinye nezongezelelo. Ezo zililo becala zisetyenziselwa nangokukrola ubushushu aluminium ezixhathisayo kunye namalungu insimbi. Iimpawu of action yale compound kukuthintela Kwingabula-up izinto phezu kwencochoyi yesixhobo. Bajikeleza nokusebenzisa i viscosity ephantsi njenge isiseko iqhekeza glubokogidrirovannoy ekrwada muncu. ulwelo Ukusebenza ukuze zisetyenziswe kule isiseko EDM oomatshini abangalinganiyo izidanga ngamandla, ekusetyenzisweni kokugqiba imisebenzi ukujika Smith kwizikhundla zemveliso.

iimpawu eziphambili olwelo

Imbonakalo iimpawu ezinjalo ulwelo azifani kakhulu kuxhomekeka kudla ezisetyenzisiweyo. Ngokuqhelekileyo, le elisezantsi viscosity ubunzima omdaka, izithunzi leyo zinokwahluka. Kweli qela umsebenzi yokusebenza enye yeempawu ibalulekileyo lexinene. Standard igrisi ukubunjwa ukususela okupholisa onokuxinana kuluhlu ukususela 1100 ukuya 1200 kg / m ^3. Nangona kunjalo, eli zinga zinokohluka ngexesha eyimveliso mxube. Kwakhona coolants ziqulathe ion esebenzayo imixube ezithile. 1% nesisombululo zolwelo yale Ixabiso lingaba malunga 10 pH. Abavelisi ngokuqhelekileyo bacebisa ukusetyenziswa ezaqanjwa kanzulu ngokuphindwe ka-1-3%. Kodwa kuxhomekeke indawo yokusebenza eyenziwayo kunye nezinto ekujoliswe kuwo, eli xabiso nga kwandiswa. Ngoko ke, kucetyiswa ukuba usebenzise mxube 4-hprotsentny, kunye nentsimbi elukhuni ukunyuka isalathisi ukuya kwi-7% kwaye nangenxa umsebenzi lokusila.

Iimpawu ngokwembono njengesipholisi

Kukho iindlela ezahlukeneyo delivery, isicelo kunye nokusasazwa ulwelo kwi imiphezulu functional ukuthambisa ajikeleze. Asingabo bonke zineemfuno ekhethekileyo zokuthambisa ngokubhekiselele kwizakhiwo emzimbeni, kodwa kwezinye iimeko ibalulekile kuba kucacisa uhlobo kunxibelelwano ngolwimi. Ekugqibeleni, oku kuchaphazela ukusebenza komsebenzi ukwimo ngokwayo. Umzekelo, ukuba njengesipholisi ngenxa izixhobo kumatshini zenkcenkce, ngoko kwindawo yokuqala isantya esihlambo feed. Ngako oko, amacandelo lula, kokukhona lisebenza ngokusulungekileyo iya kuba ukuthambisa ajikeleze kule ilungu kusikwe ngexesha lokusebenza. Kwakhona uthatha iqhezu kwamasuntswana ngamnye ingqalelo lulwelo. Ngamazinga aphezulu feed, ezichaphazela kakubi iimpawu kumphezulu womhlaba, deforming kuyo. Ukongeza, kubaqhubi kufuneka ithathele ingqalelo iqondo lobushushu jet ze sizamkele luhlenga-hlengiso amaxabiso abo okanye ezinye iimeko yendawo yokusebenza kunokwenzeka.

iipropati Technical kunye nokusebenza

iimpawu ezingundoqo kukuqinisekisa Ukupholisa kangangoko nefuthe ethambisayo xa iqatyiwe. Kwakhona, kwezinye iindawo yeemfuno eziphakamileyo kumsebenzi ukucoca, evumela inkqubo womatshini ngendlela ngexesha ukucoca kumphezulu iinxalenye. kwizinga olongezelelweyo, apho afakwa neencindi ukusika mihla, iquka bactericidal, eziphilayo, ucoceko, ukumelana iikhemikhali kunye namaqondo kakhulu. Kubalulekile ukuba kukhunjulwe ukuba izakhi yokuqaba kwaye babambelele imiphumo kakhulu kwemichiza izixhobo ezahlukeneyo, ngoko ke ukhetho iindlela kufuneka uthelekiswe ngokuchasene umgangatho yamanzi kunye nezinto ekujoliswe kulo.

imihlobo njengesipholisi

Ulwahlulo engundoqo yokuqaba ulwelo ukuba isiphumo okupholisa isekelwe imvelaphi indlela. Eyona eziqhelekileyo oyile mveliso, ezisetyenziswa kushishino kunye necandelo mveliso. Isikakhulu ke ioli elulwelo, zincediswa modifiers. Enye iintlobo ezininzi ezithandwayo zezi ongeziweyo nazo coarsely saa oyile emulsion, leyo eqalisiweyo zolwelo medium. iintlobo microemulsion nzile coolants siyakuvumela zokubumba oganikhi khompawundi semisynthetic okanye zokwenziwa olusekelwe. Ziye zanda kwaye Fast ngumphunga nomxube ukubila ephantsi, ngokusekelwe ezizizembiwa halogenated kunye nezongezelelo.

Ukusetyenziswa njengesipholisi

Le zokuthambisa zezona lwimi zisetyenziswa ifunyenwe ekuvelisweni amalungu zesinyithi, kwakunye imveliso yazo. Bathi nje ukukhusela izixhobo ukusebenza ukususela yokonakala ngaphambi kwexesha, kodwa ukuphucula umgangatho imveliso eyenziweyo. indawo yesibini kwi Isidingo sempahla yokwenza izinto ezinjalo kunganxulunyaniswa kwishishini lokwakha. Kweli candelo, ukusetyenziswa coolants kubangelwa ngumnqweno ukuba ukunika izixhobo zokwakha iimpawu zokuzikhusela, zokuhombisa kunye Ipeyinti zokwambathisa ezikhoyo.

Izimvo zabavelisi

Phakathi abavelisi ezininzi njengesipholisi zingahlukaniswa inkampani Proma, "Univeko" yaye "Messer". brand wokuqala malivakale ngenxa kunikezelo indlela ephumelelayo zesinyithi yokwenza bekholosile iindlela ebandayo kunye nobushushu. Ukubuyekezwa Umsebenzisi we engamanzi bonisa ukuba inkqubo yemveliso kunokwenzeka ukuba kuncitshiswe umtshato yokusebenza, ukuphucula imveliso kunye nokwandisa ukulunga. "Univeko" inkampani kusekwa kwinqanaba langoku imveliso iziselo ethambisayo xa iqatyiwe. Eli qela iikhompawundi kwenziwa ngokususela inhibitors ngokudleka lusebenze bume zolwelo, nto leyo kakhulu ecandelo zokwakha abathengi. Njengoko for the brand "Messer", iimveliso zayo isetyenziswa kakhulu kwimisebenzi machining eliphezulu-ngqo. Izinto eziluncedo ze ezinjalo abasebenzisi ulwelo ziyakuquka iipropati anticorrosive eliphezulu mikrobobrozheniyu ukuxhathisa, kunye nococeko lokusingqongileyo.

isiphelo

technology processing Modern ezibilinini etyhidiweyo ngokuthe ukusuka kwiindlela zemveli yokugaya impembelelo. Kolu lwazi, nokuncipha ukuselwa zokuzikhusela ukwandisa uzinzo kwezixhobo izibonelelo. Kodwa lona luhlala neshishini apho ulwelo yokusika nangoku efanelekileyo. Oku ikakhulu ulwakhiwo, ubunjineli, amayeza kunye nobunjineli yombane. Enye into kukuba ngo kakhulu kwiindawo ezikhethekileyo ifuna zintsonkotha ngakumbi iimpawu zabo zobugcisa nezokusebenza izinto, ezifuna ukuba kusetyenziswe kwezithako ophezulu zobugcisa kunye modifiers.
