Ama-primers amahle kakhulu wensimbi yemoto enama-galvanized
Okuqukethwe
Omakhenikha bezimoto abasaqalayo bavame ukuzibuza ukuthi hlobo luni lwengxube okufanele luthenge. Ngisho nokwazi ukubunjwa kwesixazululo esidinga ukufakwa ngezingxenye zemoto ezinamathayela, akwenzeki ngaso sonke isikhathi ukunquma ngokukhethwa komkhiqizo. Kukhona abakhiqizi abaningi emakethe abanikeza ama-primers ezimoto ahlukahlukene. Ukusiza izingcweti, sihlanganise ama-primer angu-3 aphezulu okufaka uthayela okuzenzakalelayo.
I-primer iyingxenye ebalulekile yokulungisa umzimba wemoto owenziwe ngensimbi. Ikhwalithi yokugqoka ngopende wokuqeda kanye nempahla ye-varnish incike kwisixazululo esisetshenzisiwe.
Iziqalo zokulungisa umzimba: inhloso
I-primer iyinhlanganisela ye-liquid edingekayo ukuze kulungiswe ubuso bemoto ukuze kusetshenziswe upende. Abadwebi bezimoto abangenalwazi bavame ukwenza amaphutha lapho beqala ukukhanda imoto enothayela ngaphandle kokuzama ukuthola injongo yale ngxube. Impahla ngayinye ayifani kuphela ngomkhiqizo namanani, kodwa futhi ekubunjweni, okuthinta izakhiwo ezithile zokugqoka. Ngokuya ngohlobo lwe-primer yokucubungula imoto, isetshenziselwa:
- ukuqinisekisa ukunamathela okuqinile kwensimbi ukudweba;
- ukwanda kwezakhiwo ze-anticorrosive;
- ukugcwalisa ama-pores kanye nemihuzuko emincane esele ngemuva kokugaya umshini;
- ukuhlukaniswa kwezingqimba ezingahambelani, okuthi, uma kuhlangene, kunganikeza ukusabela - ukuvuvukala kopende.
Izinhlobo zokuqala
Namuhla, emakethe yezimoto kunikezwa izinhlobonhlobo eziningi zezingxube, ngosizo lwazo izinto ezisetshenziswayo. Bonke bahlukaniswe ngamaqembu amabili amakhulu:
- okuyisisekelo (ama-primers);
- okwesibili (izigcwalisi).
Ukufakwa kwe-galvanizing ngama-primers ayisisekelo kufanelekile ezimbonini lapho kukhiqizwa khona izimoto. Ezisesibili zivame ukusetshenziswa ezitolo zokulungisa izimoto lapho kulungiswa izimoto.
Izinhlobo zokuqala
Inhlabathi yokuqala
I-primer isetshenziselwa ukumboza insimbi "engenalutho", esengozini kakhulu yokugqwala. I-primer eyinhloko isetshenziswa ngaphambi kokufaka i-putty noma ungqimba lwesinye isisombululo se-liquid. Yenza umsebenzi wokuvikela, ukuvimbela ukubukeka nokukhula kokugqwala. Futhi, i-primer yemoto engenalutho iba i-adhesive "umlamuli", ehlinzeka ngokunamathela okuqinile kwensimbi kungqimba olulandelayo lomsebenzi wokupenda.
Inhlabathi yesibili
I-filler isebenza njenge-filler ne-level. Umsebenzi wawo oyinhloko ukugcwalisa ama-pores kanye nama-craters akhiwe ngesikhathi se-puttying, kanye nokuqeda imiphumela yokugaya okungaphumeleli, ukulinganisa amalunga kanye nokuguqulwa. Iziqalo zesibili zinokunamathela okuhle nokumelana nokugqwala, kodwa lezi zici ziphansi uma ziqhathaniswa neziqalo.
Izici ze-galvanizing primer
Indawo yensimbi inokuthungwa okubushelelezi okungaziboleki kahle ukudweba. Zonke izingcweti ziyazi ukuthi kuyadingeka ukuqinisa insimbi yemoto ukuze kuqinisekiswe ukunamathela kwayo emsebenzini wokupenda. Ngaphezu kwalokho, amashidi ensimbi ngokwawo anokumelana nokugqwala okuphezulu, kodwa uma kwenzeka ingozi encane, i-zinc ibhujiswa kalula. Ngenxa yalokho, imoto ivikelwe ngokungalingani ekugqwaleni, okuholela ekubukeni kwe-foci of corrosion.
Isici esibalulekile se-primer yensimbi yemoto enothayela ukuthi okokuqala kudingekile ukunciphisa imisebenzi yokuvikela yokumboza ngokuyinamathisela nge-asidi. Kulokhu, i-primer izokwenziwa ngokuphumelelayo ngangokunokwenzeka.
Indlela yokuqalisa insimbi yemoto enama-galvanized
Ngokusho kobuchwepheshe, indawo yensimbi engenalutho kufanele iphathwe ngengxube efanelekile ye-primer. Ngemuva kwalokho, kungenzeka ukwenza ukugqoka kokuqeda ngamapende nama-varnish, okudingeka futhi kukhethwe kahle.
I-Primer yensimbi yama-galvanized
Kukhona ama-primer atholakala ngokwentengiso aklanyelwe ngqo izindawo ezingaphezulu ze-zinc. Uma kucatshangelwa ukuthi imoto isebenza ezimweni ezinolaka, ukuze kufakwe izinga eliphezulu, kufanele kukhethwe i-primer esekelwe epoxy. Iqinile, imelana nokulimala kwemishini, inokumelana nomswakama ophezulu. Kukhona futhi izingxenye ezimbili ze-primer-enamels ezisetshenziswa ensimbi "engenalutho" futhi ngesikhathi esifanayo zisebenza njenge-topcoat.
Ngaphambi kokutshala, kubalulekile ukuhlanza ubuso othulini nothuli. Insimbi kufanele yome ukuze kungabikho ukusabela kwamakhemikhali okwenzeka ngesikhathi sokusebenza okungathinta kabi ukugqoka. Isixazululo se-primer sikulungele ukusetshenziswa ngendlela ye-aerosol.
Penda izindawo ezinamathayela
Akwamukelekile ukumboza insimbi ngamafutha noma amapende e-alkyd nama-varnish. Ukusebenzisana kwabo ne-zinc surface kuzoholela ku-oxidation, ukwehla kwezakhiwo zokunamathela, okuzobangela ukuvuvukala nokuxebuka kopende. Akukhuthazwa futhi ukusebenzisa izingxube eziqukethe ithusi, ithini, i-antimony. Banciphisa kakhulu ukuqina kwendawo ependiwe. Ngensimbi eyakhiwe, kungakuhle ukuthi usebenzise upende:
- impushana;
- urethane;
- i-acrylic.
Okungcono kakhulu upende we-powder, owenziwe ngesisekelo se-epoxies nama-polymers. Isetshenziselwa ukukhiqizwa kwezimoto zokudweba, njengoba inamandla amakhulu nokuqina. Okuwukuphela kokungalungi kwe-coating ukuthi kunzima ukuhlobisa.
Inhlabathi ye-phosphate
Ama-primers amahle kakhulu wensimbi enama-galvanized
Omakhenikha bezimoto abasaqalayo bavame ukuzibuza ukuthi hlobo luni lwengxube okufanele luthenge. Ngisho nokwazi ukubunjwa kwesixazululo esidinga ukufakwa ngezingxenye zemoto ezinamathayela, akwenzeki ngaso sonke isikhathi ukunquma ngokukhethwa komkhiqizo. Kukhona abakhiqizi abaningi emakethe abanikeza ama-primers ezimoto ahlukahlukene. Ukusiza izingcweti, sihlanganise ama-primer angu-3 aphezulu okufaka uthayela okuzenzakalelayo.
I-"ZN-Primer" i-epoxy yezimoto iyomisa ngokushesha yamaphaneli omzimba wensimbi namashisela
I-primer ifaneleka kakhulu ezimotweni ezinathayela zokudweba, ihlinzeka ngokuvikeleka kwensimbi ephezulu ekugqwaleni nasekubambeleleni okuhle. Ingxube isetshenziselwa ukwelapha imizimba yemoto, okokusebenza kwamanzi kanye nezingxenye ezingaphansi kokugqwala. Ukwakheka kuhlukaniswa nokungabikho kwama-smudges lapho kusetshenziswa ngokuqondile, isivinini sokumisa ngokushesha, ukuhambisana nezinhlobo ezahlukene zoqweqwe lwemoto.

I-aerosol primer HB BODY 960 ophuzi okhanyayo 0.4 l
I-primer enezingxenye ezimbili ilungele ukusetshenziswa ku-zinc, i-aluminium, i-chrome, futhi evame ukusetshenziselwa umsebenzi womzimba wemoto. Ngenxa yokuqukethwe kwe-asidi ekubunjweni, ingxube isetshenziswa njenge-primer. Kodwa, ngokwezibuyekezo, abalungisi bezimoto bakhetha ukumboza imoto enama-galvanized nale primer ukuze bagcwalise ama-pores kanye nemifantu emincane ngesisombululo. Ngemva kokufaka i-ejenti endaweni eyonakele, kwakheka ifilimu evimbela ukukhula kokugqwala okungenakucimeka. Ngemuva kokusebenzisa ingxube ye-primer, kunconywa ukusebenzisa i-koqweqwe lwawo eyengeziwe, okuzoba isihlukanisi phakathi kwesendlalelo se-asidi nejazi eliphezulu.

I-Primer yensimbi ekhandiwe nensimbi i-NEOMID engu-5 kg
I-primer yengxenye eyodwa, inhloso eyinhloko ukuvikela ubuso ekugqwaleni. Inikezwa ngomumo, ngakho-ke asikho isidingo sokuxuba ingxube nama-hardeners nezinye izinto ngaphambi kokusetshenziswa. Umhlabathi unezici zekhwalithi ephezulu futhi udingeka phakathi kwezingcweti ezichwepheshile. Okuwukuphela kwe-negative yijubane lokumisa - amahora angu-24.

Izindlela Zokukhetha
Lapho ukhetha i-primer yokucubungula imoto, kutuswa ukuthi ucabangele:
- ukuqina kwe-coating ebuyekeziwe;
- ukumelana namathonya emvelo;
- izakhiwo zokunamathisela;
- umsebenzi wamakhemikhali;
- ukumelana nomswakama nesithwathwa.
Ungapenda kanjani insimbi enama-galvanized ukuze ingaqedi isikhathi eside ngangokunokwenzeka
Ngaphambi kokusebenzisa i-primer kanye nopende ensimbi yemoto eyakhiwe, lungisa indawo:
- Yenza ukuhlanza izingxenye zemoto othulini, ukungcola, iminonjana yokugqwala. Ukuze wenze lokhu, sebenzisa imishini ye-sandblasting, i-sandpaper, amanzi anensipho.
- Bese ugcoba ubuso nge-concentration ephansi ye-phosphoric acid noma ingxube ye-acetone ne-toluene ngesilinganiso sika-1 kuya ku-1. Kuvunyelwe ukugcoba ukugcoba nge-parafini, umoya omhlophe, i-bleach ene-chlorine.
Ngokushesha ngemva kokwenza lezi zinyathelo futhi ukomisa imikhiqizo esetshenzisiwe, penda indawo. Kunconywa ukuthi uqedele ukudweba kungakapheli imizuzu engu-30 ngemva kokuba ulungise imoto. Lokhu kuzokwandisa izakhiwo zokunamathisela zezinto, kanye nokuhlinzeka ngokugqoka okuphezulu. Ukuze uzuze imiphumela ephezulu, kunconywa ukusebenzisa izendlalelo ezingu-2-3 zejazi eliphezulu.
