Priming koqweqwe lwawo ku nokugqwala: ukubuyekezwa, Ukucaciswa

Uma wema phambi umsebenzi ukuvikela ebusweni kusukela nokugqwala, ungasebenzisa koqweqwe lwawo priming. Isetshenziselwa yensimbi steel imikhiqizo, futhi izisekelo okuyinto zambozwa ukugqwala. Izingxube okunjalo singasetshenziswa ngisho izinsalela ubudala enamathela zokuhlobisa okuyinto ngokwanele uvalwe waxhumana kwensimbi futhi ayikwazi ukususa ngesikhathi umsebenzi wokwenza amalungiselelo ngaphambi kokufaka kwengoma. Lokhu kusebenza izakhiwo ezinkulu sensimbi, okuyinto unephrofayela eziyinkimbinkimbi, kanye nemikhiqizo kanye wonke bobunjwa kakhulu nosayizi. Uma imithi yabo kunzima ngokwanele (isibonelo, kungenzeka emagalaji, ngehele noma kocingo), khona-ke udinga priming koqweqwe lwawo yezinjongo ngenhla. Bayoba yokubhekana ngokuphumelela ne imisebenzi, edlulisela umsebenzi eside kwamanzi.

izici

zisetshenziselwa Uhlelo ukwakhiwa ngenhla, uma ukulungisa ezidingekayo yokudweba imoto izingxenye, okungukuthi, amakhanda, amaphiko, nokunye. Uma ingxube sisetshenziswa 3 izingqimba ke ingasetshenziswa ngisho njengendlela ukuma enamathela yedwa metal evele okuyinto kumele zisetshenziswe bedle amathonya ozungeze umhlaba wethu. Ifanele ukucutshungulwa enjalo futhi imikhiqizo esetshenziswa inqubo ukusebenza emkhathini zezimboni equkethe amagesi ezonakalisayo futhi evala, ikakhulukazi ezithinta ebusweni metal nensimbi. Uma uyikha phezulu le emva isicelo we koqweqwe lwawo phansi kungathinta usawoti namanye reagents zamakhemikhali, izinga lokushisa ukusetshenziswa bengase bazikhandlele degrees 60, base eliye kahle kusetshenzwe primer kuchaziwe, uzobuyisa izinga libe nezici futhi ukubukeka ekhangayo.

Uma kudingeka, singasebenza phezu ukuvenisha Ukuvikelwa ngohlobo cholesterol, NC, fl. Nokho, pre-isidingo isisekelo ukumelana amahora 24, omisiwe at vivo. Kubalulekile ukuhlola indlela koqweqwe lwawo kahle zalala kwamanzi futhi kukhona isilungele ukusebenza.

izici omuhle

koqweqwe lwawo Priming anezici eziningi ezinhle, phakathi kwabo bungabonakala ukuthi compounds ngqo isebenze imisebenzi emithathu, okuyilezi: primer, nokugqwala ukuguqulwa enamathela futhi umhlobiso. Lapho ingxube kwakuyovela isidingo sokusebenzisa izinto zokuzivikela. Umsebenzi kungaba kwenziwe ngaso lokushisa kuma-degrees -10. Uma kudingekile, ungakwazi okufanele athuthwe futhi agcinwe koqweqwe lwawo priming at kwamakhaza ashubisa umnkantsha. Ngemuva kokufaka isicelo ebusweni seyomile ngokushesha. Konke lokhu kwenza abathengi ukuyenga ukukhetha kwakho umusa kwalo mkhiqizo, okuyinto uthathé ukuma ofaneleyo emakethe.

Incazelo priming koqweqwe lwawo

Priming koqweqwe lwawo izilinganiso lapho ungafunda kulesi sihloko zokwenziwa resin, futhi inqubo ukukhiqizwa izithako kunezelwa izithasiselo eziyisisekelo oyifunayo, ezihogelwayo, zombala, anti-ukugqwala okufakiwe kanye fillers. Ngemva nomkhiqizi bumbela uncoma ukugcina ukwakheka izinyanga ezingu-18, yingakho ngaphambi kokuthenga kuyadingeka ukuze unake okukhethekile usuku ukwakhiwa. Uma kudingeka, ukugcinwa noma ezokuthutha isitsha kufanele igcinwe uvalwe waqiniswa, baligcine kude amadivayisi bafudumale. Kubalulekile ukuze awuvikele elangeni futhi umswakama. Yiqiniso, phansi-koqweqwe lwawo on metal kufanele igcinwe kude nezingane. izici engeziwe omuhle bungabonakala ukuthi ezokuthutha kungaba kwenziwe ngesikhathi kwamakhaza ashubisa umnkantsha.

Izibuyekezo umthengi

Priming koqweqwe lwawo nokugqwala izilinganiso zazo ethulwa ngezansi uyakwazi lula inqubo umbala ezindaweni kobuso umxhwele. Abathengi bathi lezi Izingxube asetshenziselwa kalula for ekwelapheni kanzima ukuze afinyelele izindawo, lokhu kungenxa yokuthi ngaphambilini asikho isidingo ukuhlanza kumila ukugqwala. Umenzi uthi izimo zalesi sihlahla asetshenziswa izithasiselo ekhethekile eyenziwe eJalimane, okwazi ukuwaguqula imikhiqizo ukugqwala ibe izakhi ezingase kunzima ukuncibilikisa futhi kuvimbele ukuqhubeka ukugqwala phezu. Abathengi, esikhundleni salokho, gcizelela ukuthi koqweqwe lwawo phansi, izici zazo okusesihlokweni esithi, usinikeza isivikelo eside lwezihloko nensimbi evele. Kuwufanele enakile futhi yokuthi ukwakheka has adhesion okusezingeni eliphezulu, lokhu kusikisela ukuthi ingxube ithobela kakhulu nge ebusweni ibuthuntu. Ungakwazi ukubala on isigaba esifushane omiswe. Ngakho, ungqimba ngamunye bome kusuka imizuzu 30 kuya amahora kuncike lokushisa kuma. Esimweni sokuqala kukhona isidingo sokugcina izinga lokushisa ngaphakathi degrees 20. Yezandla ukhetha priming koqweqwe lwawo ku nokugqwala, ngisho nalapho kunesidingo ukucubungula moisten ebusweni. Ngemva eyakha lesi enamathela is, emelanayo amafutha, ama-ejenti asemkhathini, usawoti kanye amagesi ezonakalisayo.

Ngaphambi kokuba uthenge umkhiqizo, kumele uzijwayeze ukugeleza, okuyinto mncane impela. Ngakho, 7 square metres uzodinga 1 kg kwengoma. Uma ufuna ukwandisa isikhathi omiswe, kubalulekile ukuba silondoloze lokushisa elikhulu kanye nomswakama, njengoba inketho yokugcina, kumelwe ukuba ngaphezulu kuka-70%.

amanothi Isicelo

Uma ukhetha ukusebenzisa koqweqwe lwawo priming ku nokugqwala, ebusweni zigezwe umgwengwezi ubudala, kodwa lokhu kufanele kwenziwe kuphela uma kucatshangwa ngokuqinile ngokwanele. Lokhu kusebenza futhi esikalini okuxekethile ukugqwala. Kubalulekile degrease base 647 imimoya kuphela noma amaminerali. Ngaphambi kokusebenzisa i-koqweqwe lwawo priming kufanele zixutshwe. Sebethule kufanele kwenziwe ibhulashi, roller noma sprayer upende. Uma indlela yokwakheka akuyona ukungaguquguquki efanelekayo, kungashiwo buhlanjululwe kuphela 647.

izinyathelo zokuqapha

Uma kukhona isidingo e-indlu umsebenzi, kumelwe siqinisekise ukuthi izimo zinezikhathi provetrivaemostyu ezinhle. Ngemva kokuphothulwa zokukhwabanisa ezidingekayo pholisa igumbi emini. Kufanele kusetshenziswe ukuze bavikele izandla zakho phezu amagilavu zenjoloba. Intfo tekuphatsa lokutsite kumele ilahlwe njengodoti wasendlini.

isiphetho

Akubalulekile nje kuphela ukukhetha ukwakheka ilungelo ukuvikela ebusweni, kodwa futhi ukuze uhambisane ubuchwepheshe sokusebenza kwawo. Ngakho, koqweqwe lwawo priming okumele asetshenziswe ezingeni lokushisa ezisukela -10 kuya +35 degrees.
