I evele degreased? Imoto ungakwazi degrease ebusweni phambi yokudweba?

Lapho udinga upende kocingo noma ipayipi lensimbi, akunandaba ukuthi futhi lokhu kusho ukuthini umsebenzi kuzokwenziwa. Kodwa kungenye into into uma kuziwa imoto. Ngamunye umnikazi inqubo imidwebo emzimbeni kubaluleke kakhulu ukuthola okungcono yi kungenzeka. Ngakho-ke, akukho amathuluzi akhethekile nalolo. Isinyathelo sokuqala siwukuba ukupenda umsebenzi - lena ukulungiselela owandulelayo umzimba. Ngokuhamba misebenzi nge imoto wasusa upende omdala. Khona-ke, i-metal kumele ngempela kube degreased bese abashayeli babhekana nezinkinga. Zama ukuthola lokho Kwamanzi degreased ezimotweni zanamuhla futhi indlela yokukwenza kwesokudla, ukuze uthole ikhwalithi ephezulu imiphumela.

Yiziphi izindlela

Ngokuvamile ukubhekana ifilimu okunamafutha okuyinto ngemuva, e elidala imoto abathanda kukhona indwangu Lint-free, ziphathwe iyiphi kuphela. Ochwepheshe rekomenduut enze lokhu inqubo ngendlela. inketho okunjalo kufanelekile kuphela uma udinga ukucubungula kuphela esigabeni ezinye ezincane. Uma ubheka uhla imikhiqizo umsebenzi wokwenza amalungiselelo ngaphambi imidwebo, olutholakalayo namuhla, kungenzeka ukwaba ezinye izimali kuka degrease ebusweni metal. Lokhu kumakhemikhali awuketshezi ezahlukene kanye nezinto Lokudabuka organic, emulsions, kanye nezixazululo ezikhethekile, okuhlanganiswayo ku zokwenziwa yokuwasha izithasiselo. Ochwepheshe batusa usebenzisa kuyilokhu kwamuva. Le mithi ngempumelelo nangokuzethemba uwine hhayi kuphela ifilimu okunamafutha, kodwa ukulwa engengaphansi ngempumelelo ukungcola kanye nemiphumela ukugqwala.

umoya White

Enye yalezi ezihogelwayo - ajwayelane zonke umoya emhlophe. Isetshenziselwa at esigabeni sokuqala ukucutshungulwa emzimbeni. Ngokulandelayo, ngezinyathelo zikanokusho usebenzisa inhlanganisela utshwala nge orthophosphoric acid. Le isixazululo, wayazi kahle uhlambulule iminonjana amafutha ebusweni metal. Kodwa kunezinye izidakamizwa abangalayisenswa degrease kobuso imoto. Elinye ithuluzi ezifana - trichlorethylene. Lona omele kunazo owaziwa leqembu ezihogelwayo. It engena ukusabela asebenzayo on contact ngemitimba aluminium. Ngokuhamba ukusabela labelwe izinto ezivuthayo, ezikhulisa ingozi yomlilo uma izingozi. Sebenzisa kuba engathandeki kakhulu. Uma trichlorethylene bazothini ngamanzi, ngenkathi emuva bakha mass okunamathelayo, ukususa akubi njalo elula. Uma kukhona ezinye option kunokuba degrease ebusweni imoto ke lokhu izidakamizwa uzokwenza. Kodwa kuyasiza kuphela ukungabi umswakama phezu.

Spetspreparaty izocubungulwa

Professionals asebenesikhathi eside wahlanganyela Umdwebo izimoto, bazi futhi batusa ukusetshenziswa amathuluzi akhethekile - awayona imbangela imililo, futhi bungakhiphi iyiphi ingozi abantu chemical compounds. Kodwa Wabasaqalayo ngokuvamile abasinaki iseluleko futhi okuthiwa "ukuthi" kuyini engcono degrease kobuso imoto. Lokhu ngokuvamile kusetshenziswa kaphalafini, uphethiloli, acetone, ngisho udizili. Empeleni, konke okungenhla ingasetshenziswa kuphela lapho eliseduze esitolo autocosmetics mayelana 100 km.

Uphethiloli, idizili, acetone, esikhundleni umoya mhlophe

Abantu ababengakaze balwazi emsebenzini wokulungiselela umdwebo, ngokuvamile udidekile umoya nomhlophe kanye nezinye izinto ezifana uphethiloli, iziketekete kanye diesel - zonke lezi uketshezi zifana kakhulu iphunga. Kodwa umehluko obusebenzayo phakathi kwabo incane. Ziyakwazi nenye hydrocarbon ukuthi akhiqizwa the ziphuzo zazihluzwa of petroleum izingxenyana zaso. Zonke izinto kuthiwa yahlakazeka ezahlukene ngokuphelele asphalt mastic nezimagqabhagqabha noma amafutha. Kodwa diesel kaphalafini kunzima kakhulu ugeze off, nakuba isimiso sawo Site degreasing. Ngezinye professional imoto izona zisebenzisa kaphalafini, kodwa lisebenzisa imishini ephambili, okwenza kube lula ukususa iminonjana izinto futhi iphunga. Egalaji ngaphansi ukucutshungulwa utawubese yingozi. Nge ukuqapha okukhethekile ongasisebenzisa acetone, kanye kumakhemikhali awuketshezi №646 noma 645.

Antisilikon

Antisilikon kuka degrease ebusweni, ezibhekwa lesikahle for bonke abashayeli abavamile abanquma ezilungiselela umzimba ngenxa yokudweba ngezandla zakhe. Ngalezi kusho kungenzeka hhayi kuphela ukususa amafutha ebusweni ifilimu. Antisilikon efanelekayo ukuze bahlanze ukungcola nothuli. Ukusetshenziswa lezi zimali ngokufanele futhi lapho ohlela ibala umdwebo indikimba yabadala bakulelo bandla. Ngaphezu kwalokho, idatha ikhombisa ukulungiselela degreasing esihle umphumela, futhi akababhubhisi metal noma upende omdala.

Antistatic

I degreased plastic ebusweni? Antistatic kuyoba belondekile ngangokunokwenzeka. Iqiniso ukuthi plastic anezakhi gesi nokuheha uthuli. Lokhu kungaba ikhanda yomnikazi - ezimweni ezinjalo kuba nzima kakhulu ukususa okunamafutha ifilimu. Le nkinga zingaxazululwa ngokushesha okukhulu futhi kahle ngosizo umenzeli antistatic. Ukwakheka kususa kahle amafutha nothuli.

Izimali ngesisekelo alkalis

Lena enye iqembu izidakamizwa kunokwamukela evele degreased lapho yokudweba. Ngokusebenzisa lezi zindlela eyaziwa zonke ukufihla yokuwasha izingoma ezithinta i alikhali. Asiza hhayi kuphela ukwenza nge high kahle degreasing, kodwa futhi kulula ukususa ezihlukahlukene izinto. Kodwa ukusebenzisa imikhiqizo ane-alikhali ngokuqapha. Lapho ukwelashwa sekudlulile sekuphelile, imoto kungcono ukubeka zasendlini egumbini ihlanzekile futhi yomile lapho umzimba kungaba Ewufrathe kahle. Ngo iningi lezi zakhi ngaphandle alikhali, kungathola emulsifiers ahlukahlukene. Lezi zinto zehlela kuthiwa wasithukuthelela ukudla okunamafutha okushisa kusuka degrees 60. Ngemva uDries Ukwakheka, ifilimu okunamafutha oshiywe metal - ke kuyoba lula ukususa. Uma umnikazi imoto wanquma ukuba ngilwe nesikhulu amafilimu okunamafutha ngale ndlela, kubalulekile ukugwema yesivini esindayo. Foam Bubbles ngeke likwazi ukunikeza izimo ezifanele ukuqala nokuxhumana amafutha. Umthelela oyifunayo ngeke.

izindlela electrochemical kokuphatha

Kuyinto nangenye okufana nalokho kungenzeka degrease ebusweni phambi nokudweba. Nokho, akuyona efanelekayo kulabo ungumnikazi igalaji noma ikhaya workshop. Ukuze le nqubo, uzodinga ugesi amaza ezimbonini. Iphuzu elibalulekile - the polarity. Okunqumayo uhlobo metal. Ingabe ukuxhuma anode ukusebenza ku degreasing steel kanye cathode esetshenziselwa izinsimbi non-ayoni.

nokuhlanzwa multi-esiteji

Okokuqala, ukucutshungulwa umzimba ngomoya emhlophe. Kuthiwani uma phezu zikhona izimpawu ukugqwala? Kulokhu, ebusweni baphathwe orthophosphoric acid ne alcohols. Lokhu Ukwakheka inhlanganisela ETHYL utshwala endaweni isilinganiso 15%. Futhi ingxenye okuxubile amanzi wali band acid e isilinganiso 1 kuya kwele 5. Ngokukhethekile, i emulsifier isetshenziswa - OP-7 ogelezayo nokumanzisa ejenti e isamba 0.5%. Kuyadingeka 0.1% nitrobenzene. Ekhaya, uthole ingxube kunzima ngempela - ezinye izinto ngeke itholakale emakhemisi. Kubalulekile ukukhumbula ukuthi indlela yokwakheka iyingozi empilweni.

isifinyezo

Ukuphendula umbuzo ngalokho degrease imoto, kufanele acabangele imingcele ethile - kusho ukusebenza kahle, intengo yayo kanye nenzuzo. Ideal - omunye elihlangabezana nazo zonke lezi zimfuneko, kodwa ukuthola okuthile okudayiswayo kanje kunzima kakhulu. Ngaphezu kwazo zonke lezi zici, kubalulekile ukuba acabangele umonakalo ukuthi uyoqeda ku metal noma empilweni yomuntu. Ngakho-ke kuyadingeka ukuze uthole ulwazi kakhulu mayelana izidakamizwa. Ungabi kahle ukuthenga imishini zokuzivikela ukuze zokuphefumula ipheshana - buso kanye respirators.
