Izinhlobo zama-primers zemoto, okuyi-primer ongakhetha kuyo imoto yokudweba

Ngaphambi kokukhetha i-primer yemoto, kufanele uqale unqume ukuthi yimiphi imisebenzi ezosetshenziswa. Bese ufunda izici zengxube, funda ukubuyekezwa kwabashayeli.

Uma umsebenzi wokudweba uhlelwe ngemoto, ngakho-ke kubalulekile ukwazi ukuthi yiziphi izinhlobo zama-primers zemoto. Ukunamathela komdwebo wokupenda emzimbeni kanye nokumelana kwawo nokugqwala kuncike ekukhethweni kokubunjwa okufanele.

Yiziphi iziqalo zezimoto

Le ngxube enezici ezivimbelayo isetshenziswa njengesisekelo ngaphambi kokudweba imoto. Isebenzela ukulinganisa ubulukhuni ebusweni futhi inikeze uxhumano oluqinile nongqimba lomsebenzi wokupenda.

Ukunciphisa umzimba

Uma upende ungabambeleli kahle emzimbeni, khona-ke ama-microcracks nama-chips azokwenzeka. Ngenxa yokuklwebheka okuncane ngemva kokungena kwamanzi, ukugqwala kungase kuvele. Ukuze ugweme lokhu, kuyadingeka ukumisa imoto nge-primer ngaphambi kokudweba. Le nqubo ibizwa ngokuthi i-passivation. Kwenziwa kusetshenziswa isibhamu esikhethekile, i-roller noma i-spray can. Ngemuva kokucubungula insimbi, i-koqweqwe lwawo lusetshenziswa.

I-Auto primer inokumelana nokugqwala okungcono kunomzimba wemoto yensimbi. Lokhu kungenzeka ngenxa yezithako ezikhethekile ze-zinc ne-aluminium.

Inhloso yokuqala kanye nokusetshenziswa

Ingxube iyisixhumanisi esivikelayo esixhumanisayo phakathi komzimba nopende osetshenzisiwe. Kunezinhlobo ezahlukene zama-primers zemoto futhi isicelo sabo singaba kanje:

1. Ukucubungula okuyinhloko kwendawo yensimbi. Ukuze wenze lokhu, thatha ukwakheka okuminyene okusekelwe ku-epoxy.
2. Amaphutha asendaweni eshelelayo. Sebenzisa i-putty ewugqinsi enokumelana kahle namanzi.
3. Ukuvikelwa kwesakhiwo sengxube ezintweni zokupenda ezibolayo. Kulokhu, kusetshenziswa i-sealant.

Ukuze uqalise kahle imoto, kufanele ulandele imithetho:

• Indawo okumele ilashwe kumele ingabi nakungcola namafutha.
• Ukufafaza ukwakheka, sebenzisa ibhulashi lomoya noma ithini lesifutho.
• Ngaphambi kokuhlangana, ungqimba kufanele lome.
• Penda ngenhlanganisela yomkhiqizo ofanayo.
• Gcwalisa umzimba nge-putty ewuketshezi.

Uma ingxube iqukethe i-hardener kanye nesisekelo sezinto, khona-ke isilinganiso sabo kufanele sibonwe. Uma isilinganiso sezingxenye siphulwa, inhlabathi ngeke ikwazi ukuqinisekisa ngokugcwele izimfanelo zayo zokunamathela kanye ne-anti-corrosion.

Izakhiwo eziyinhloko nezici

Ukuvimbela i-delamination ngesikhathi sokudweba, amakhono okudweba awadingeki ikakhulukazi. Kubalulekile ukwazi izici zengxube ngayinye. Isibonelo, awukwazi ukusebenzisa i-anti-corrosion auto primer eminingi. Kufanele isetshenziswe ungqimba oluncane oluqinile. Bese uvumela ukuba zome ngaphambi kokumboza ngengxenye elandelayo. Uma le nqubo ingalandelwa, ukunamathela kuzowohloka, okuzoholela ekuqhekekeni komdwebo.

i-acrylic primer

Ngokusho kwezakhiwo zabo kanye nesimiso sesenzo se-primer, kukhona:

• Ukudlula. Basebenza ukwenza oxidize insimbi enamathela ngomthofu.
• I-Phosphating. Vikela emiphumeleni emibi yokuguquguquka kwezinga lokushisa.
• Ukuzivikela. Ingxenye eyinhloko i-zinc, evimbela ukubhujiswa kwensimbi.
• Iyalungisa. Ukuze ukwelashwa ukugqwala.
• i-insulating. Zivikela ekungeneni komswakama.

Amamiksi afika ezingxenyeni ezi-1 noma ezi-2. Esimweni sesibili, ukulungiswa kuqukethe into eyisisekelo kanye ne-hardener, ngenxa yokuthi izinto ezisetshenzisiwe zoma ngokushesha. Emakethe ungathola ukwakheka kotshwala. Akunconywa ukuwasebenzisa, njengoba kunzima ukucubungula nokubhubhisa umzimba.

Izinzuzo zokusebenzisa

Ungasebenzisa ingxube ebusweni nge-aerosol noma isibhamu. Inketho ngayinye inezinzuzo zayo kanye nokubi.

Kunconywa ukukhetha i-primer yemoto yokudweba kwabaqalayo ngendlela yamathini.

Izinzuzo:

• izilinganiso ezihlangene;
• akukho ukulungiswa kwengxube edingekayo;
• ukusebenza okulula;
• ukumbozwa okufanayo;
• isicelo esikahle ezindaweni zendawo.

Ukupenda imoto ngale ndlela kungasebenzi kahle. Inqubo izothatha isikhathi eside futhi ifaneleka kuphela ukusebenzisa ingxube ewuketshezi.

Izinzuzo zesibhamu se-spray:

• inikeza isivikelo esiphezulu kuwo wonke umzimba;
• impahla yoma ngokushesha.

Phakathi kokushiyeka, kubalulekile ukuqaphela ukuthi ukwakheka kufanele kuhlanjululwe esitsheni, futhi isibhamu somoya kufanele sithengwe ngaphezu kwalokho.

Izinhlobo zama-primers ezimoto

Zonke izingxube zihlukaniswe ngamaqembu ama-2 amakhulu:

• Ama-Primers (ukucubungula okuyinhloko). Nikeza ukunamathela komzimba emsebenzini wokupenda, futhi uvimbele ukubonakala kokugqwala.
• Izithako (fillers). Isetshenziselwa ukupholishwa kwendawo nokuvikela kuma-chips.

Izingoma eziningi zanamuhla zihlanganisa zonke izimfanelo zazo zombili izinhlobo, kodwa kungcono ukusebenzisa imikhiqizo ehlukene yokucubungula insimbi nepulasitiki.

I-Acid nenhlabathi esebenzayo

Lesi i-wash-primer yokufaka kumzimba wemoto ongenalutho. Ingxenye ihlanganisa ama-polyvinyl resins, futhi i-phosphoric acid isebenza njenge-catalyst. Ngenxa yalokhu kwakheka, kwakhiwa ifilimu eqinile ekwazi ukumelana nokugqwala nokuhlakazeka. I-primer esebenzayo isetshenziswa ungqimba oluncane (9-10 microns). Ingena ensimbi futhi ifake isandla ekwenzeni kwayo.

I-Primer yemoto

Ingxube iyingxenye eyodwa nambili. Iqinisa ngokushesha. I-Putty akufanele isetshenziswe kuyo, ngaphandle kwalokho ukusabela kwamakhemikhali kuzokwenzeka ngaphansi komdwebo futhi ifilimu yokuzivikela izobhujiswa. Ngakho-ke, ukwakheka kwe-asidi kuhlanganiswe ngopende we-acrylic.

I-Epoxy primer

Le ngxube yokwelapha ngaphambilini iqukethe ama-resin nezithasiselo ezisebenzayo zekhwalithi ephezulu.

Lapho welashwa, i-primer idala ungqimba oluqinile lwe-anti-corrosion, olumelana namazinga okushisa ngisho nangaphandle kwe-varnish.

Ngemuva kokumisa (cishe imizuzu eyi-10-15), impahla ingafakwa ngesihlabathi ngephepha elikhethekile futhi ifakwe nge-acrylic.

I-epoxy primer ingasetshenziswa ngaphansi kwe-polyester putty. Ngaphezu kwalokho, kuvunyelwe ukudweba ingxube emanzi noma uma usebenzisa ama-hardeners.

I-Acrylic yezingxenye ezimbili zokuqala

Lesi sigcwalisi senzelwe ukugcwalisa ama-pores kanye nokukhubazeka kwemaski kuphaneli yomzimba ngemva kokugaya. Ngokuya ngesilinganiso sokuxuba sezinto eziyisisekelo ne-hardener (kusuka ku-3 kuya ku-5 kuya ku-1), ine-viscosity ehlukile kanye nogqinsi lwesendlalelo.

Ingxube enezinhlayiya ze-acrylic isetshenziswa njengento ephakathi ngaphambi kokufaka umsebenzi wokupenda. Kuyi-sealant futhi inezici ezinhle zokunamathela. Imibala eyinhloko yokugcwalisa esetshenziselwa ukunciphisa ukusetshenziswa kopende impunga, emnyama nomhlophe.

Umhlabathi wepulasitiki

Le primer isetshenziselwa izingxenye zemoto yepulasitiki (bumper, fenders, hood). Ingxube ivamise ukuba nengxenye engu-1 ecacile noma ephuzi. Ifanele izinhlobo eziningi zepulasitiki. Okunye ukwakheka akuhambisani ne-polypropylene.

Umhlabathi wepulasitiki

Ngaphambi kokusebenzisa i-primer, indawo ye-silicone yengxenye iyashiswa (isibonelo, ngokuyibeka ngaphansi kwemisebe yelanga) futhi iyancipha. Enye inketho ukugeza ipulasitiki ngaphansi kwamanzi ashisayo, anensipho futhi yomile. Bese usebenzisa ingxube yokunamathisela endaweni encane.

Sibutsetelo sabakhiqizi abathandwayo

Kunezinhlobo ezahlukene zama-primers emoto emathini noma emathini emakethe. Amamodeli alandelayo athandwa kakhulu.

Isihloko	Uhlobo lomhlabathi	Tara	Izici zokwakhiwa
Vikela i-340 Novol	I-Acid	Ibhange	Ivikela ngokuphelele imihuzuko nama-chips
UMZIMBA 960		I-canister, ibhodlela	Akudingi ukugaya. Iyaqina emizuzwini eyi-10.
I-Spectral Ngaphansi kwe-395	I-Epoxy	Futha	Ilungele ukuhlikihla
Novol 360		Ibhange	Ukunamathela okuhle kunoma iyiphi indawo
I-Reoflex	I-Acrylic		Ifanele umdwebo omanzi
	Okwepulasitiki	Ithini le-spray	Iyoma ngokushesha (imizuzu engu-20)

Ama-primers asekhaya angcono kakhulu, ngokwemibono yabasebenzisi kanye nokubuyekezwa, abhekwa njenge-Zincor Spray kanye ne-Tectyl Zinc ML. Womabili amalungiselelo athuthukiswa kucatshangelwa isimo sezulu saseRussia. Zisetshenziswa ebusweni bemoto nge-aerosol. Ziqukethe ama-inhibitors akhethekile avimbela ukubonakala kokugqwala. Izindleko ezijwayelekile ze-spray can zingama-ruble angama-600-700.

Indlela yokukhetha i-primer efanele

Kungakhathaliseki ukuthi iyiphi indlela ezosetshenziswa ekucubunguleni umzimba, kufanele uthenge ingxube yekhwalithi ephezulu. Izidakamizwa ezishibhile zinezakhiwo ezibuthakathaka zokunamathela kanye ne-anti-corrosion. Kusuka kubo, ngokuhamba kwesikhathi, ukudweba kugxusha futhi kuvela imifantu.

Ngaphambi kokukhetha i-primer yemoto, kufanele uqale unqume ukuthi yimiphi imisebenzi ezosetshenziswa. Bese ufunda izici zengxube, funda ukubuyekezwa kwabashayeli.

Awukwazi ukuthenga imikhiqizo ezinkampanini ezingaziwa kancane. Umzamo onjalo wokonga imali ungaba nomthelela omubi empilweni yomsebenzi wokupenda. Ukuze uthole ukunamathela okungcono komphumela wokunamathela, kunconywa ukuthatha izingxube ezivela enkampanini efanayo.
