Uma isikhwama sesikhumba se-pu silengiswa ngephutha ngesikhathi sisetshenziswa, empeleni kulula ukusiklwebha.Ngalesi sikhathi, kuyoba lusizi uma isikhwama singakasetshenziswa isikhathi eside.Kufanele sifunde
Uzoba namakhono athile okulungisa izikhwama ezikhutshiwe.
1. Uma isikhwama sesikhumba se-PU sishwabene kancane, ungasebenzisa i-swab encane kakotini ukuze umanzise iqanda elimhlophe, uhlanganise ngokucophelela indawo eyonakele ukuze ulenze flat, futhi ngokuyisisekelo ngeke ibonakale ngemva kokumisa;
2. Uma isikhwama sesikhumba se-PU sinombala ogqamile, singaxuba impushana yesicathulo enombala neqanda elimhlophe bese silicubungula ngokwendlela yokuqala.Ungasebenzisa futhi i-nail polish;
3. Uma isikhwama sesikhumba se-PU sinendawo enkulu eyonakalisiwe noma indawo eyonakele ibonakala futhi inzima ukuyilungisa, ungasebenzisa ezinye izinhlobo zokuhlobisa ezincane ukumboza indawo eyonakele.
Ingabe isikhwama sesikhumba se-pu sihlala isikhathi eside?
Izikhwama zesikhumba ze-PU empeleni zihlala isikhathi eside, zigcinwe kahle, futhi zinempilo ende yesevisi.
I-PU iyi-polyurethane, futhi isikhumba se-PU siyisikhumba se-polyurethane.I-PU isifinyezo se-English ploy urethane, igama lekhemikhali lesiShayina i-polyurethane, izinga layo lihle noma libi, abaningi
Izikhwama zesikhumba zohlobo olukhulu zisebenzisa kakhulu isikhumba sePU esingenisiwe;Isikhumba esihambisana ne-PU ngokuvamile siwungqimba lwesibili lwesikhumba oluhlangothi lwaso olungemuva luyisikhumba senkomo.Ingaphezulu limbozwe ungqimba lwe-PU resin, ngakho-ke libizwa nangokuthi isikhumba senkomo sefilimu.Intengo yayo ingaphezulu
Izinga lokusetshenziswa elishibhile neliphezulu.Ibuye yenziwe ibe izinhlobonhlobo zamabanga ahlukahlukene ngokushintshwa kobuchwepheshe, njengesikhumba senkomo esinezingqimba ezimbili esingenisiwe, ngenxa yobuchwepheshe baso obuyingqayizivele, ikhwalithi ezinzile, izinhlobo zamanoveli, njll.
Isikhumba esiphezulu ngaphambili, intengo kanye nebanga alikho ngaphansi kwesendlalelo sokuqala sesikhumba.Ngokusekelwe kwezemvelo, isikhumba se-PU asigcini nje ngokuthungwa kwesikhumba sangempela, kodwa futhi sihlala isikhathi eside kakhulu.Emazweni angaphandle, ngenxa yokuvikelwa kwezilwane
Umthelela wenhlangano yokuvikela, ehambisana nokuthuthukiswa kobuchwepheshe, ukusebenza kanye nokusetshenziswa kwesikhumba se-PU kweqe elesikhumba semvelo.
Izici zezikhwama zesikhumba ze-pu
1. Amandla aphezulu, mncane futhi anwebeka, athambile futhi abushelelezi, ukungena komoya okuhle kanye nokungena kwamanzi.
2. Isenamandla amahle okuqina namandla okuguquguquka ekushiseni okuphansi, ukumelana nokuguga kokukhanya okuhle kanye nokuzinza kokumelana ne-hydrolysis.
3. Ukuguquguquka nokungagugi, ukubukeka nokusebenza kusondelene nesikhumba semvelo, kulula ukuwasha nokususa ukungcola, ukuthunga kulula.
4. Ingaphezulu libushelelezi futhi lihlangene, futhi lingasetshenziselwa ukwelapha okungaphezulu nokudaya, ngezinhlobonhlobo ezihlukahlukene.
Indlela yokuhlanza izikhwama zesikhumba ze-pu
1. Ngokuvamile, izikhwama eziningi zokuhlanza kuqala zisebenzisa amabhulashi okuhlanza noma izindwangu zekotini ezihlanzekile ezifanele izinto ezihlukahlukene zokususa uthuli nokungcola.
2. Uma izikhwama zesikhumba zisulwa ngesicoci sesikhumba, indwangu yokuhlanza ilensi yezingilazi ngokuvamile ishibhile futhi kulula ukuyisebenzisa.Ngeke iklwebhe isikhwama sakho osithandayo, vele usisebenzise ngokulinganayo.
Ingakwazi ukubuyisela isicwebezelisi sesikhwama.
3. I-eraser yepensela ne-ball-point enombala owodwa ompunga nomhlophe kuzo zombili iziphetho, ingasetshenziswa njengethuluzi lokuhlanza izikhwama zesikhumba ze-PU, uma ingcole kancane, ungasebenzisa irabha elimhlophe ukuze usule ipensela kancane.
Sula ngobumnene ukuze ususe;ukungcola okungathí sina kungasuswa ngokuhlikihla irabha elimpunga ekupheleni kwepeni lebhola.Isizathu siwukuthi ukungqubuzana kunamandla, kodwa isandla kufanele sibe lula ukugwema ukulimala esikhwameni.
