I degrease kwamanzi? Degreaser iimoto

Ukususela kumaxesha ngamaxesha kukho imfuneko ndazikhuhla ndawo kutyetyiswa phezu komzimba imoto. Xa iimeko isixeko oko kungenziwa kuphela xa loo yokuvasa imoto. Noko ke, uninzi bamafutha iyafuneka xa ethi isithuthi. Wenza ntoni na? Ngokusebenzisa inkqubo efanayo inika coupling ezilungileyo umphezulu umzimba epeyintwe. Yintoni kwaye degrease njani, kufuneka isigqibo phambi kokuqalisa umsebenzi. Kubangel 'umdla ukwazi ukuba indlela eqhelekileyo ngeenjongo ezinjalo alusoloko ezifanelekileyo. Ukongeza, unyango umphezulu kwayo kuyimfuneko ukuze bakuthathele ingqalelo ezinye bokuqonda. Ngoko ke yintoni degrease kwamanzi?

Kuthetha ntoni oku ukuba

, Kubalulekile ukwazi ukuba kutheni oku kuyimfuneko phambi kokuba uphendule lo mbuzo, yintoni degrease komhlaba phambi ukupeyinta. Ngokuqhelekileyo, lo wentsimbi iphathwa kunye iikhompawundi ezifana kuphela nokugcinwa adhesion okuqhelekileyo izinto apho umzimba refinishing. Kwezinye iimeko kuyimfuneko. Kwiimeko apho imoto repainted ngokupheleleyo, umzimba kufuneka igqunyelelwe ngomaleko primer okhethekileyo. Ukuqinisekisa adhesion elungileyo, kusenjalo nanamhlanje kufuna bamafutha.

Adhesion, enyanisweni, - bamba izinto omnye nomnye. Oku konke kwenzeka kwinqanaba eziphilayo. Ukuba intsimbi okanye phakathi primer kanye ukutyabeka ngepeyinti iya kuba ngomaleko amanqatha, adhesion yabo ayanelanga. Oku ligcina imbonakalo isithuthi. Ukusuka nayiphi lokungcangcazela ipeyinti kuya kunyothulwa.

Yintoni kubi ngenxa adhesion

Degreaser iimoto hayi kususa ngamanqatha kuphela. Ukungcola, ezahlukeneyo organic, izinto olunamafutha imvelaphi yendalo, njalo njalo - konke oku kunciphisa adhesion izinto kwinqanaba eziphilayo. Ukongeza, le adhesion ichaphazela oxide obhityileyo umboniso. Kubonakala ngathi umboniso irusi okungephi phezu komzimba. Lo mboniso Bhanya-kwakhona kucetyiswa ukuba ususe. Xa ususa i uqweqwe akaphumeleli ngokupheleleyo, kuyimfuneko ukuba ukujika ube compound ozinzileyo yemichiza oko akusithelisi adhesion metal kunye nepeyinti kwinqanaba eziphilayo.

I degrease komhlaba phambi kokuba kuncanyatheliswe okanye ukupeyinta

Amaninzi, "umoya white" isetyenziselwa yonyango umzimba. Noko ke, abaninzi xanisa kuyo iindlela ukunyamezela separafini okanye oyile idizili, njengoko bazenze zambi phantse ivumba efanayo. Umahluko phakathi kwezi izinto lincinane kakhulu. Zombini ezi zihlanganisi i umxube carbohydrate. Iveliswe ulwelo efanayo amaqhezu ulwelo.

Ezinye iimbekiselo zibonisa ukuba "umoya white" - uhlobo mnene separafini. Kubalulekile ukuphawula ukuba sibonelelo kakuhle iyachithakala ngamanqatha, asphalt, amabala irabha kunye yemastic. Ngokungafaniyo separafini, "UMoya White" lula ukuhlamba imoto plain ngamanzi. Zombini ezi zihlanganisi ezilungele imiphezulu bamafutha. "UMoya White" - yikhompawundi kukhanya vaporized ngokuyinxenye kwaye intsalela iindlela ukuwonakalisa ukutyabeka emva ukupeyinta.

Ukuba ndisebenzisa separafini

Bamafutha - inkqubo elula onokwenziwa ekhaya. Eyona nto ibalulekileyo - ukukhetha isixhobo ekunene. Ezinye izikhululo zokuhlamba professional kusetyenziswa iparafini kuba basebenzisa izixhobo ezikhethekileyo ukusingatha umzimba. Oku kukuvumela ukuba ukususa ngokupheleleyo into ukusuka kumphezulu, eshiya ivumba layo. Ukuba bamafutha of iimoto lwenziwa egaraji, kuba ezi njongo kucetyiswa ukuba usebenzise "umoya emhlophe" okanye imali esekelwe kuyo. Kubalulekile kakhulu ukuba uwuthenge imichiza esele hydrotreated. Ngalo myinge, kufuneka sinikele ingqalelo ekhethekileyo, ingakumbi xa kufakwa izinto eziveliswe ekhaya.

Yintoni ukusetyenziswa ayikhuthazwa

Yintoni degrease umphezulu, nokuba asimele sisebenzise? Abaninzi singacebisi ukusetyenziswa diesel, zepetroli diesel. Kakade ke, ukuba degreased kakuhle. Noko ke, izinto ezifana kunokusenzakalisa.

Amanyathelo kufuneka usebenzise izinyibilikisi inani elingako №645, №646 njalo, kwaye acetone. izinto ezinjalo lula zichithakala nje organic, ubumdaka, namafutha omnquma, kodwa Coatings. Unyango lwe umzimba kuvunyelwa kunye nemixube acetone nje kokuba lokufaka.

Ukuba akukho lithetha okhethekileyo, kunokwenzeka ukuba ukusebenzisa isisombululo iviniga zesiqhelo, ugalelwe ioli amathontsi ambalwa isepha ukuba tableware.

Esetyenziswa kwi mveliso

Le mveliso isicelo carbonate solution sodium (35-50 g / L) okanye isisombululo sodium hayidroksayidi (90-150 g / l). Le degreaser iimoto kufuneka isetyenziswe ngokuqaphela okukhulu. Phambi kokuba baqalise umsebenzi, kucetyiswa ukuba banxibe iiglavu njengoko sodium ngokwayo ezonakalisayo kakhulu. Isisombululo Awukwazi ukususa nje amanqatha kumphezulu umzimba, kodwa adla kungena ulusu phezu kwezandla.

Ukongeza, izisombululo obrak abakwazi ukususa ngokupheleleyo amabala neoli grease eqinileyo. Ezo zililo babe detergency eliphantsi. Sebenzisa kwealkali kucetyiswa kuphela emva kokuba ukufudumeza 90 ° C. Awunako angalizisi ithumba. Kufuneka kuqatshelwe ukuba izisombululo emuncu zisuswa kakuhle umboniso oxide, kodwa kakuhle yoxukuxwa ngamanqatha. Ngoko ke yintoni ngcono ukuba degrease umphezulu na umzimba?

trichlorethylene

Kwezinye iimeko, kuba kungengokwentlambululo yendawo umzimba isetyenziswa trichlorethylene okanye izinto eziye kuye kohlelo. Noko ke, le arhente kuneengxaki. Abanakukwazi ukuba isicelo aluminum. Xa imveliso trichlorethylene isetyenziswa kuphela bamafutha zesinyithi ayoni.

Phezu ukuqhagamshelana zealuminum iyeza zingabanga uqhushumbo. Kwakhona akucetyiswa ukuba waxuba amanzi trichlorethylene, ekubeni le ngcina uqalisa ukwakha kunye nobunzima ilukhuni. Kwiimeko ezininzi, iyeza ayisetyenziselwanga ngendlela esulungekileyo kodwa ngohlobo emulsions. Le degrease kobuso, kuyimfuneko ukumisela kwangaphambili ukuba akukho ngakumbi umonakalo umzimba isithuthi.

Ukucoca ngezigaba eziliqela

Ukuba awuyazi ukuba degrease njani kwaye yintoni umphezulu, kuyenzeka ukubhekisela kwiingcali. Ngo-mveliso, ukucocwa oluqhutywa kwizigaba ezininzi. Xa oku kwenzeka kwi inyathelo defatting lokuqala. Okokuqala komhlaba umzimba iphathwa with "umoya white". Ukuba but is kwezinye iindawo ubethwe ngokudleka, kucetyiswa ukuba ce kunye nomxube utywala kunye phosphoric acid. Ngoko kuyimfuneko ukuba agcine ipesenti kwezinto:

1. Phosphoric acid + namanzi 1 ukuya 5. isisombululo kufuneka ibe ukusuka 65 ukuya 75%.
2. utywala Isopropyl - ukususela nge-13 ukuya kwi-18%.
3. utywala ethyl - 10 ukuya ku-14%.
4. Le emulsifier OP-7 - 0.5%.
5. Nitrobenzene - 0.1%.

Ukwenza olunjenge ekhaya kunzima. Nangona kunjalo, ubugcisa bale mihla kuvumela abavelisi abaninzi ukuvelisa udidi oluthile abacoci. Baya lula isicelo ekhaya. Olu didi kwezinto ebizwa antisilikony. Nika iingcebiso ngokubanzi yokusetyenziswa akunakwenzeka, njengoko nganye iipropati yayo engamanzi. Kufuneka kuqatshelwe ukuba antisilikony ezininzi umxube izinyibilikisi eziliqela organic leyo zinetyhefu esezantsi. Zinokusetyenziswa ngaphandle ekunkwantyiseni kobubi empilweni. Noko ke, umphezulu umzimba phambi titoloveta kuyacetyiswa ukususa ngeempahla zabo.

izincomo

Ngoku uyazi ukuba degrease kumphezulu. Ngaphambi kokuba uthenge special funds kufuneka athathe ingqalelo ezinye bokuqonda. Nokuba ukusetyenziswa imixube ezingezo-eyingozi Kucetyiswa ukuba banxibe iiglavu kunye yokugquma iikoma.

Ukwenza iinkqubo bamafutha kuyimfuneko ukusebenzisa iitawuli ezimbini: omnye ifunelwa isicelo ekwakhiweni, kwaye eyesibini - ukususa iintsalela.

Unyango kufuneka kwenziwe emva sanding kwaye nje phambi nokupeyinta. Izahlulo ezenziwe-aluminiyam, kuyimfuneko ukuba anikele ingqalelo ekhethekileyo. Asizizo zonke izinto ezikhuselekileyo intsimbi. Faka ukwakhiwa inki ngqo kwi kumphezulu degreased akunconywa, kuba umzimba kufuneka akakhululeki ku lobushushu egumbini.
