Coatings: iinjongo kunye nobuchwepheshe

izakhiwo Metal kuneengenelo ezininzi kuthelekiswa kunye nezakhiwo ezenziwe ufakelo lwesamente, kuqala ibe ubunzima kakhulu ngaphantsi lo gama kugcinwe amandla kuyimfuneko. Ukongeza, ubume metal ibe zezikhali, yaye ukwakhiwa kwazo kunokwenzeka nangaliphi na ixesha enyakeni. Kodwa metal lokukhuselwa kwimiphumo eyingozi ngeemeko zokusingqongileyo (ilanga, amanzi, umoya, utshintsho obushushu), yaye kunye neendlela ukhuseleko ekhethekileyo (nokolula, nitrotsementirovanie) wasebenzisa indlela elifana nokupeyinta isinyithi. Umaleko coating unako ukukhusela nesinyithi kwiindawo zonke ezi zinto zingasentla. Ngaphezu kwako konke, umbala, wentsimbi isicelo ukudlulisela i imbonakalo ubuhle yokwakha.

ingqalelo ekhethekileyo kufuneka ihlawulwe kukhetho lo Coatings. Metal inki kufuneka ube ezizodwa neempawu ezithile. Okwangoku, oku kubangela ukuba akukho bunzima, umenzi nganye kuquka ngokuhambelana yawo okukhethekile iipeyinti ukuba metal.

Painting kwezakhiwo ngentsimbi - ngenkani kunye nomsebenzi ethatha ixesha elide, nto leyo efuna izakhono zobungcali. Oku kungenxa nje kuphela kubuchwepheshe ukutyabeka, kodwa nesibakala sokuba izakhiwo ezinjalo zinkulu kakhulu kwaye ibenze ingubo ayinikezi ilula kakhulu. Uyilo bantu badla obudaywe alpinism kwezoshishino kuphela iingcali.

Coatings uqala kumphezulu zoqeqesho olugunyazisiweyo. Loo preliminary umsebenzi odingekayo ukuphucula adhesion (adhesion), kunye ukutyabeka lweziqalelo yesinyithi. Inyathelo lokuqala kukuba ukususa yepeyinti endala ukuba ikhona. Emva koko, a lokucheba NOKUCUKUCEZA umhlwa. Inyathelo elilandelayo liya kuba ukucoca yonke kumphezulu kuqhuma manual, mechanical okanye esirhabaxa ukusuka ukungcola nothuli - eli nqanaba kuyo nayiphi na imeko zilubona, nokuba kumphezulu engaphandle ibonakala uhlambulukile. On metal usoloko iqulethe amasuntswana amazwe, kwaye ukuba kususwe, ipeyinti iza kuqengqeleka na izinto okanye izakhiwo ziya kuba umaleko non-uniform, kukhokelele kwinto yokuba umbala izakhiwo zentsimbi kuya kwenziwa kakubi.

Eminye kunokwenzeka lwenziwa ipolishi phezu - le nkqubo kunceda ukuphucula adhesion yepeyinti nentsimbi. Inyathelo elilandelayo - bamafutha, kuliwa kusetyenziswa iimali emulsion obrak okanye emuncu. Emva ukuhlamba kufuneka alinde - uyilo kufuneka yome nko ngaphambi ukupeyinta. Inkqubo wokugqibela ekulungiseleleni priming - unyango enye okanye ezimbini iimaleko izinto ezikhethekileyo, umaleko yesibini isicelo kuphela emva kokuba wokwaphusa ngokupheleleyo yokuqala. Emva priming uyakwazi ukuqhubeka ngqo amabala.

Into kuphela ukuba ukukhumbula - musa ukwenza breaks elide phakathi ukulungiselela komhlaba, priming nokusebenzisa ipeyinti, kuba isakhiwo lingaba kwakhona kwaye kugubungela ubuxoki embi. Ke ukuba bathi bonke imisebenzi zenziwa ngokuchanekileyo, nobomi ukutyabeka ayikho ngaphantsi kwe-3.5.
