Ke ohi loli (coolant): Mea Maluna, noi

Metalworking kaʻina ua inherently me ke kū'ē ikaika e ia lŘlŘ ma waena o ka workpiece, a me ka mea paahana pili. He mea oi loa akaka no ka wā huli a me ka mīkini wili pōhaku hana, i ka wa a ka mea paahana ka loa wela, anuanu extrusion, kiʻekiʻe-māmā Ai Pohaku Ai pae. , Pili kū'ē ka poʻea pau i premature Wear o ka mea paahana, me ka ea deformation o ka workpiece, loli waiwai o ka metala ma muli o ka overheating. E emi ke kū'ē max koi he kūikawā ana loli (coolant) a me ka mahana emi iho.

Kiko'î Mea Maluna coolants

General Mea Maluna coolants lawe mai ma luna o kekahi mau mea kiko'î:

• Ma ke kumu o ka eiiiiiaiou. Hua mai la i ka aila coolant, a i ka nānā 'ana ma kaʻaila kā mea kāhinu, holoholona, a me kaʻai i ka momona,.
• By ala e kuhikuhi ana. Emulsol - he pau huahana me ka lōʻihi holopapa ola a oaoieei-emulsion, hoʻomākaukau koke ihola mua hoʻohana o ke kiaʻana i kāna e like me GOST.
• Ma physical a me mechanical kiko'î - (viscosity),ʻakika helu, waihonaʻike wahi. Ka hope ano kumu o ka palapala noi o coolant aila no ka wela hahi.
• E like me ka palapala noi kahua. Ua produces nāʻano likeʻole o nā coolants no kekahi pae'ōnaehana kumu o ka palapala noi. Kemikala ana loli no ka ea deformation ana, coolant no lathes a me ka mīkini wili pōhaku machines.

Ke kemikala wai wailana coolant paʻa EFELE CF-621 me ke kiaʻana i kāna i manao ia no ka machining o ka nou ana la o ka hao, steels, me kuhiliʻole a me ka oka, titanium, Aluminum a me ke keleawe oka a pau. Kēia coolant Russian? Iecaianoaaiiuo mai he Amber waihoʻoluʻu a me ka maikai caramel aroma. Ia, aole ia e apo ia formaldehyde, chlorine a me kiʻekiʻe amines, no laila, palekana no kānaka. I ka kemikala eiiiiiaiou me ka hou (15%) mea pōhaku aila haku mele 'ana, keia emulsion i ka haʻahaʻa lilo, he ano o ka mea pōhaku huahana. Biostability a me ka hana ana EFELE CF-621 ae machining ke hooheheeia pāʻoihana mea emi like i nā coolant nā hoʻohui like.

Mea Maluna o ka haku mele 'ana coolant

Ma o ka haku mele 'ana o ka coolant hoomaopopo i ke kēia mau' ano:

• Oil - mea haʻilula keimikala o na eiiiiiaiou a i immiscible i ka wai. Base aila emulsion i paraffin, mea pōhaku a me kaʻaila kā mea kāhinu, (60-95%). E hōʻoi 'i ka laulā o Anati-Wear, kū'ē, ka popopo i loko o ka haku mele' ana nā likeʻole mea hoʻonui a me nā mea kūpale. Oil emulsion noho maikai loa lubricating waiwai. Hoʻohana 'ia no ka pahee ke hooheheeia ma ka noonoo ole pae'ōnaehana' ole.
• Mea pōhaku - kumu i ka aila ma ka catalytic hydrogenation. E hoomahuahua i ka laulā o ka mea hoʻonui komo mai bipi kūpaluʻia, chlorine, luaipele, phosphorus i huiʻia. Mau mele i hoʻohana 'ia ma ia mau hoailona ia mea o ka mea hiki ke hooheheeia, e like me: ke kalai kila, Aluminum, keleawe, threading, mīkini wili pōhaku hana oka a steels.
• Wai miscible - he koʻana koko pāʻoihana ma muli ma ka mea pōhaku aila. Mau mele i maikai anuanu maila 'ka waiwai a me ka haahaa kaʻawahia, akā, me ka haʻahaʻa lubricating hana. Laulā - ka malamalama, a me ka meakino hana huli keleawe a me ke keleawe, a me ka mīkini wili pōhakuʻeli o nā 'ano o nā' ole-ferrous ke hooheheeia, wili a punching kila.
• Kemikala a semisynthetic - i ka läÿau, o ka wai, surfactants, wai wailana polymers, Anati-ka hua nui a me ka antibacterial mea hoʻonui, ka popopo nā mea kūpale. E hoomahuahua i ka lubricity ma kemikala mele i kekahi lawelawe antiwear mea hoʻonui.
• Emulsions - mele me ka kiʻekiʻe nā hoʻohui like o ka poe i hoopuehuia'ku a (particles). Emi i ka degere o ka Wear o na mea paahana, a me ka lako a me kaʻaneʻane a pau metalworking hana.

Ke 'ole a me kaʻano papa hana o ka hana o ka coolant

I ka laha ana o ka coolants ma ka mea hiki ke hooheheeia aaioee keʻano o ka hanaʻana aie i ka hoʻokō kaawale o ka anaanai surfaces o ka workpiece, a me ka mea paahana a me ka ho'ēmi i kā lākou mau ana wela. O ka hapanui o ka hoʻokō coolant ke loaʻa i nā kēia mau eiiiiiaiou i loko o kona haku mele 'ana:

• Ke kumu o kemikala mea kāhinu, a me ka holoholona bipi kūpaluʻia.
• Mea hoʻonui i hoomahuahua i ka frictional Wear a me ka lōʻihi puʻe lawelawe.
• Eiiiiiaiou, pale delamination haku mele 'ana i waho pūnaewele.
• Mea hoʻonui i pale ai ka popopo a me ka luku aku.
• Eiiiiiaiou, hoemi ka hua nui a me ka wetting o surfaces ma ka mea hiki ke hooheheeia.

Ka hoʻohana o coolant

Metalworking fluids e hoʻohana i ka lubricate a hoomaalili i ka hana i loko o kahi o ka mea hiki ke hooheheeia. Mall coolant ae e emi kū'ē i loko o ka iapaau ana ciia, hiki hoemi Wear o ka mea paahana, mahuahua ka huina hoonui e like ai ma ka hoʻomaikaʻi i ke ka nui ana o ke kaʻina hana, a, me ia i kaʻilihune, ka nohona ma productivity.

Manawa i kā lākou pono lubricating waiwai o ka coolant ho'ēmi i kā ka frictional ikaika ma waena o ka workpieceʻili, a me ka ohi kapa o ka mea paahana, ke kū'ē i ka mea hiki ke hooheheeia, ahu iho e oki ai. Kekahi oaoieei-lubricant i Nine Inch waiwai e paipai i ka emi ole wale ka frictional ikaika, akā, i ka ohi max. Hapanui coolant - surfactants me kiʻekiʻe adsorption waiwai. e hiki ke hana i ka hale hānai Auana ma ka mea hiki ke hooheheeia luna, a nunui ho'ēmi i kā kū'ē lākou. Kekahi kūikawā surfactant mea hoʻonui i ma luna o ka mea hiki ke hooheheeia "wedging" hana. Elongated nā lātoma ia mea hoʻonui hāʻule i loko o microcracks ma o ka metala luna, e like me ka auka, hiki hoʻonāwaliwali i ka mea paʻa ma waena o na (particles) o ka mea. Penei, coolant "kokua" i ka hana koʻi lipi eʻoki i ka ahu iho la, mai ka waihona ipu metala.

Ka loa, he pono ole coolant mele no ka mīkini hana

Metalworking lathes a me ka mīkini wili pōhaku machines i ua hanaʻia kēia ke kinowai.

• Emulsoles nānā 'ana i mea pōhaku a me kaʻaila kā mea kāhinu,.
• Emulsifiers me kemikala momoma nāʻakika.
• Haliu ae la ia a me ka mīkini wili pōhaku hana, ka hoʻolako 'kiʻekiʻe-māmā aaioee o kuhiliʻole a me ka oka a steels, hua mai la ia e like me ka GOST 38.01445-88. No kēia mau mea, nae kemikala mele a i ka nānā 'ana ma luna o tallow aila vysokoatomnye waiʻona mai ke kino triethanolamine.
• Sulfofrezoly - i aloha hoomaemae aila läÿau, a me ka luaipele-i loaʻa i huiʻia. Mai no ka wai, alkalis, nāʻakika. Oia coolant no machines i ka pono ho'ēmi i kū'ē, mai ole i ka popopo.

Noi o ka coolant i ka'aloʻahiʻa iapaau ana o ka mea hiki ke hooheheeia

Kēia papa hana ua pili me ka nui metala-kekahi ikaika a me ka pili ma waena o ka hāʻuleʻana o ka workpiece, a me ka mea paahana. Coolant hoʻohana 'ia i loko o ia keʻano o ka hanaʻana, e loaa ana i ka (viscosity) me ka nui loa kiʻekiʻe. Ke ano hiʻona o nā mele, metalworking puʻe i:

• Lawa (viscosity).
• Ia'ku i ka fracture a me ka hoʻolaʻaʻia ma kiʻekiʻe ana wela ana.
• Pili vodnografitovye tonkocheshuychatogo mele me ka hoʻi o graphite ma muli o ka aila mai paha.

Hiʻona o ka palapala noi a oki fluids

No ka hou efficient ana o ka coolant e noonoo i kekahi mau mea lula.

• Palena iki o ke kinowai pele, nānā 'ole no paha ia mea koʻana koko paha emulsion - 10-15 H / min.
• He mea nui i ka coolant kahe mea i loko o ke kahua o ka hoʻonaʻauao 'ana i ka i kā mākou nui o ka wela. I ka hoohuli ana - o ka wahi ma luna a na? Inoaia hookaawale, mai ka workpiece.
• Ka lako hou i ka coolant e halihaliia oia iwaho koke. I ka wā o ka coolant ma hope o kekahi ana loa wela meaʻoki e pio ole, kūpono ana ma ke kahua o ka mawae i loko o laila.
• ka wā 'aʻole pili Coolant huli brittle metala (ke keleawe, hao, etc.). I ka haliu ae la i na mea ai,? Inoaia liʻiliʻi, a ua hui ia me ka coolant, hiki clog ka mīkini hana huahelu (kaa caliper, ke alakai ponoi), a hiki aku i ka premature Wear a me ka hoʻokō 'ole' ana o kēia mau eiiiiiaiou.

? Iecaianoaaiiuo a me ka pūnaewele o kaʻoki fluids

Ma waho aʻeo ia lōʻihi waho pūnaewele o ka hoʻopauʻana o ke mele, noʻonoʻo, a ua hanaʻia eiiiiiaiou no ka makaukau o ke kinowai, hakuloli ia ana o kekahi mau hana. Coolant, coolant, ke kumukuai o ka i hilinaʻi nuiʻano nui ma luna o ka haku mele 'ana e like me ka kekahiʻano o ka hana i loko o këia lä ka makeke ua hoʻomaopopo no 70-160 rubles / hano no ka makaukau-i mele a wahi lulu nā hoʻohua a me 105-290 rubles / hano o ka haole? Iecaianoaaiiuo. Ka awelike waiwai o ke kiaʻana i kāna mea 240 R / hano. Mua ana i ka wai ma ke kēia kaʻina hana:

• Hooeueu ana i hana 'ia ma ka eiiiiiaiou hoʻouka kekahi ma luna o ka haku mele' ana ae hahi Mahana O Ke Kai (60-110 0 C).
• Ka Ikepili o ka haku mele 'ana e like me ka GOST.
• Ke hoomakaukau mele e waiho ma ka hana kūikawā ipu, hiki e lawe mai papa'āweʻaweʻa kemika hahana maoli nō kēia a me ka hooeueu ana.
• Ma ka hoomakaukau ana i ka emulsion, i ka hoike o ka mea hoʻonui, a ua lawe ma luna o ka lahilahi vibratory emulsification.
• Refilling ana e ai ana i hoʻomākaukauʻia.
• I i na mele i ua hoʻohaumiaʻia. Hoʻolako 'ia' ana o coolant huikala nenoaiu o ka mea hiki ke hooheheeia residues. Neoneo huahana i hiki ole ke kuleʻa ua holoiʻia no ka hoʻolilo.
