Imiphezulu degreased? Imoto uyakwazi degrease komhlaba phambi ukupeyinta?

Xa kufuneka ukupeyinta ucingo okanye umbhobho yesinyithi, kwaye ayinamsebenzi oko kuthetha lo msebenzi uya kwenziwa ngayo kunye. Kodwa ke, yenye into xa kuziwa imoto. kumnikazi ngamnye kule inkqubo kumzobo umzimba kubaluleke kakhulu ukufumana isiphumo kangangoko kunokwenzeka. Ngoko ke, akukho izixhobo ezikhethekileyo ezibalulekileyo. Inyathelo lokuqala kukuba ukupeyinta umsebenzi - oku kulungiselelwa owandulelayo umzimba. Ekuhambeni ezi imisebenzi kunye imoto wazisusa ipeyinti endala. Emva koko, lo yesinyithi kufuneka kubeka degreased uze abaqhubi beemoto bajamelana neengxaki. Zama ukuqonda ukuba yintoni na wayo degreased izithuthi mihla nendlela yokwenza oko kulungile, ukufumana iziphumo aphezulu umgangatho.

Ziziphi indlela

Amaxesha amaninzi ukujongana a kutyetyiswa umboniso esiphezu ngasemva, kwi bathandi imoto kwakude iintshengece-ezamahala ngelaphu, iphathwa nayiphi sijike. Iingcali musa rekomenduut ukwenza le nkqubo ngendlela. Loo kukhetha efanelekileyo kuphela xa ufuna ukwenza kuphela icandelo encinci. Ukuba ukhangela uluhlu lweemveliso kumsebenzi wokulungiselela phambi ukupeyinta, nto leyo ezikhoyo namhlanje, kunokwenzeka ukuba yokwaba imali kunokuba degrease umphezulu metal. Oku izinyibilikisi ezahlukeneyo kunye nezinto ze imvelaphi eziphilayo, emulsions, kunye nezisombululo ezizodwa, leyo ibandakanywa ongeziweyo isepha zokwenziwa. Iingcali Sicebisa usebenzise nguye yokugqibela. La machiza ngempumelelo nangokuzithemba uwine kuphela umboniso ezinamanqatha, kodwa akukho ngaphantsi ngempumelelo ukulwa ngothuli kunye neziphumo nokumelana.

umoya White

Enye yezi izinyibilikisi organic - liqhelekile yoomoya bonke emhlophe. Oku kusetyenziswa lokuqala inkqubo komzimba. Okulandelayo, ngamanyathelo abangcono usebenzisa umxube utywala kunye orthophosphoric acid. Le isisombululo ke ngokucokisekileyo uhlambe kude imizila grease ukuya kumphezulu metal. Kodwa kukho ezinye iziyobisi kunokuba degrease kumphezulu imoto. Omnye isixhobo - trichlorethylene. Le omele kakhulu ezaziwayo-kakuhle zelo qela organic izinyibilikisi. It Ungena ukusabela esisebenzayo ukudibana ngemizimba aluminium. Ekuhambeni basabela njani ezabelwe izinto ezinokutsha, leyo kwandisa ingozi yomlilo xa iingozi. Yisebenzise ayinqweneleki kakhulu. Ukuba trichlorethylene uya kusabela ngamanzi, ngoxa emva kwasekwa ubunzima incangathi, ukususa loo nto ilula kakhulu. Ukuba ayikho enye indlela ngaphandle degrease phezu imoto, ngoko eli chiza uya kuyenza. Kodwa isebenza kuphela xa ingekho ukufuma phezu komhlaba.

Spetspreparaty ukugaywa

Iingcali abaye kudala benza iimoto ukupeyinta, yazi nokucebisa ukusetyenziswa izixhobo ezikhethekileyo - bengengabo unobangela imililo, yaye musa ayikhuphi nayiphi yingozi iikhompawundi chemical yabantu. Kodwa wabaqalayo badla ngoyaba icebiso okuthiwa "uyazi" into kungcono degrease kumphezulu imoto. Oku kusetyenziswa iparafini, ipetroli, acetone, nkqu diesel. Enyanisweni, konke oku kungentla zingasetyenziswa kuphela xa ivenkile autocosmetics elikufutshane 100 km.

Ipetroli, idizili, acetone, njengendlela eyenye umoya abamhlophe

Abantu abangazange benza umsebenzi amalungiselelo ukulungiselela ukupeyinta, kudla bedidekile umoya emhlophe kunye nezinye izinto ezifana amafutha ipetroli, iparafini nedizili - zonke ezi ncindi ziyafana kakhulu ivumba. Kodwa umahluko ukusebenza phakathi kwabo incinci. Basimisela umxube hydrocarbon ukuba ziveliswa le ulwelo amaqhezu petroleum. Zonke izinto iqhawulwa amabala asphalt yemastic ngokugqibeleleyo ezahlukeneyo okanye amafutha. Kodwa diesel nekerosini kunzima kakhulu ukuhlamba icimile, nangona umgaqo ukuba alungele bamafutha. Xa uhlamba imoto yobungcali sebenzisa separafini, kodwa isebenzisa izixhobo ezikhethekileyo, nto leyo eyenza kube lula ukuba ukususa khondo kwezinto ivumba. Negaraji phantsi processing iya kuba yingozi. Ngononophelo ezizodwa isinye Ungasebenzisa acetone, kwaye izinyibilikisi №646 okanye 645.

Antisilikon

Antisilikon kunokuba degrease umphezulu, zithathwa ukhetho zibalungele bonke abaqhubi beemoto oqhelekileyo wagqiba ukulungiselela umzimba ngenxa yokudweba ngezandla zakhe. Xa la kuthetha ukuba kunokwenzeka hayi kuphela ukususa amanqatha kumphezulu ifilimu. Antisilikon ezifanelekileyo nokucoca ukungcola nothuli. Ukusetyenziswa kwezi mali ngeyona ndlela yaye xa uhlela ukuba angcolise ubungangamsha umzobo umzimba yasekuhlaleni. Ukongeza, i-data ibonisa ukulungiselela ifuthe bamafutha ocoliweyo, oko akuthethi kutshabalalisa yesinyithi okanye ipeyinti endala.

Antistatic

Umphezulu iplastiki degreased? Antistatic uya kuba kunqabisa ngoko kunokwenzeka. Isibakala sokuba kweplastiki uye iipropati umbane kwaye kutsala uthuli. Oku kunokuba ebuhlungu yomnini - kwiimeko ezinjalo kunzima kakhulu ukususa okunamafutha film. Le ngxaki ingasombululwa ngokukhawuleza kakhulu nangokufanelekileyo ngoncedo i-arhente antistatic. Ukwakhiwa ususa igrisi kunye nothuli ngokugqibeleleyo.

Imali ngokusekelwe alkalis

Oku elinye iqela iziyobisi ngaphezu imiphezulu degreased xa ukupeyinta. Ngale ndlela kumntu wonke ngokufihla ezaqanjwa isepha leyo ibe kwealkali. Banceda kuphela ukwenza kunye bamafutha high ukusebenza, kodwa kulula ukususa ezahlukeneyo izinto. Kodwa usebenzisa iimveliso obrak ngononophelo. Xa igqityiwe unyango, imoto kubhetele ukubeka kwigumbi ecocekileyo owomileyo endlwini apho umzimba koma ngokupheleleyo. Kwinkoliso ezi zihlanganisi ngaphandle kwealkali, uyakwazi ukubona izixubisisi ezahlukeneyo. Ezi khompawundi awasabela ngayo kunye nokutya okunamafutha kwiqondo lobushushu evela degrees 60. Emva kokuba liyalila ukwakheka, kutyetyiswa umboniso tywa phezu metal - ngoko kuya kuba lula ukuba ukususa. Ukuba umnini imoto wagqiba kulwa bhanyabhanya olunamafutha ngale ndlela, kubalulekile ukuphepha sewayini enzima. amaqamza amagwebu akakwazi ukunika iimeko ezifanelekileyo kokuqalisa intsebenziswano kunye amafutha. akayi kuba yifuna.

iindlela Electrochemical aphatha

Kuyinto enye uhlobo oko kunokwenzeka ukuba degrease kumphezulu phambi ukupeyinta. Nangona kunjalo, akukho ezifanelekileyo kwabo bangabanini igaraji okanye ikhaya kumasifundisane. Ngenxa yale nkqubo, uya kufuneka umbane ezitsho mveliso. Enye ingongoma ebalulekileyo - ezichaseneyo. Oku kumiselwa ngokohlobo ngentsimbi. Ngaba ukuqhagamshela anode ukuba basebenze bamafutha zentsimbi kunye cathode esetyenziselwa iintsimbi non-ayoni.

multi-sigaba zokuhlanjululwa

Okokuqala, inkqubo yokuqulunqwa koMthetho umzimba ngomoya emhlophe. Kuthekani Ukuba phezu kukho iimpawu nokumelana? Kulo mzekelo, umphezulu ukuba ziphathwe orthophosphoric acid kunye alkoholi. Le ukwakheka ngumxube ethyl utywala umlinganiselo we-15%. Kwakhona inxalenye elingumxube amanzi kunye phosphoric asidi om-1 ukuya 5 kokuzikhethela, i emulsifier isetyenziswa - OP-7 arhente ilele xa isixa-mali ka-0.5%. Kwakhona kuyimfuneko 0.1% nitrobenzene. Ekhaya, ukufumana umxube kunzima kakhulu - ezinye izinto ayifumaneki ngokorhwebo. Kwakhona kubalulekile ukukhumbula ukuba ekwakhiweni yingozi empilweni.

isishwankathelo

Ukuphendula umbuzo malunga degrease imoto, kufuneka athathe ingqalelo ethile iparameters - kuthetha ukusebenza, ixabiso layo kunye nenzuzo. Ideal - leyo enazo zonke ezi mfuno, kodwa ukufumana into loqoqosho efana oku kunzima kakhulu. Ukongeza zonke ezi zinto, kuyimfuneko ukuba uyithathele ingqalelo umonakalo oya kulungisa kwi ngesinyithi okanye kwimpilo yabantu. Ngoko kuyimfuneko ukuba ukufumana ulwazi ezininzi malunga ichiza. Musa ukuba kuhambe ukuthenga izixhobo zokhuselo ukulungiselela iphecana yokuphefumla - iimaski kunye respirators.
