Ukwakhiwa kopende we-PU ekunakweni kwasebusika:

I. indawo yokwakha

Izinga lokushisa lendawo yokwakha akufanele libe ngaphansi kuka-5 ℃, futhi umswakama akufanele ube ngaphezu kuka-80%.

Uma izinga lokushisa langaphakathi lingaphansi kuka-10 ℃, kuphakanyiswa ukuthi kuthathwe izinyathelo ezifanele zokushisa ukuqinisekisa isivinini sokomisa upende we-PU ngaphandle kokuthinta ukusebenza kahle kokukhiqiza.

II. Ukukhetha umkhiqizo

1. Imikhiqizo kufanele ikhethwe ngokwesizini. Ngokuvamile, upende we-Pu uhlukaniswe ukusetshenziswa kwehlobo nokusetshenziswa kwasebusika. Kulebula yesitifiketi sokuvumelana (S) kukhona ukusetshenziswa kwasehlobo kanye no-(D) ukusetshenziswa kwasebusika. Uma kungenjalo, kusho ukuthi yonke indawo. Ikakhulukazi emikhiqizweni ye-PU top coat, ekwindla nasebusika, imikhiqizo yasehlobo akufanele isetshenziswe, ngaphandle kwalokho ukukhanya kungase kube bomvu;

2. I-ejenti yokwelapha ye-Pu ehambisanayo kumele isetshenziselwe upende we-PU, ikakhulukazi i-PU primer, i-ejenti yokwelapha enokuqukethwe okuqinile okuphansi akufanele isetshenziswe ngokuthanda kwayo, ngaphandle kwalokho kuzoholela ekungaphelelini okwanele, iphunga elikhulu elisele, ukusika okungaphansi, ukugoba kwefilimu yopende, ukucwebezela okungafanele noma ubulukhuni obuphansi bopende wokuqeda, njll.;

4. Ukukhetha isinyibilikisi:

Ku-15 ℃ – 20 ℃, kukhethwa i-Pu standard diluent cj-001l noma i-SR-71;

Uma izinga lokushisa liphansi kune-15 ℃, kukhethwa i-Pu ebusika diluent cj-003l noma i-sr-73.

III. ukuxuba upende

1. Ngenxa yokushisa okuphansi ebusika, isivinini sokuphendula phakathi kopende oyinhloko we-Pu kanye ne-ejenti yokwelapha siyahamba kancane. I-ejenti yokwelapha eyengeziwe engu-10% ingangezwa endaweni ukuze kuthuthukiswe ubulukhuni kanye nokunamathela kosuku olulandelayo, okungeke kuthinte ukukhanya kwe-top coat. I-primer ingoma ngokushesha.

2. Ebusika, ukungezwa kwe-ejenti yokwelapha ye-PU clear primer akumele kudlule u-20% okungenani, kanti okwe-primer emhlophe akumele kudlule u-10%. Ungangezi i-ejenti yokwelapha eyengeziwe ngokuthanda kwakho ukuze uthuthukise isivinini sokomisa, kungenjalo kungenzeka ukuthi iqhekeke, inamathele kabi, ifilimu yopende ephukile, ukuba mhlophe kamuva nezinye izimo.

3. Ngemva kokulungiswa kwe-Pu primer kanye ne-finish coat, kufanele zisetshenziswe zingakapheli amahora angu-3-4 (ngaphandle kwesisekelo esimhlophe, kufanele zisetshenziswe zingakapheli amahora ama-2).

IV, abanye

1. Ukuze uthole izinto eziyisisekelo ezinokuqukethwe okuphezulu kwamafutha noma umswakama, kuyadingeka ukulawula okuqukethwe komswakama wokhuni ngo-8-12%, bese uvala izinto eziyisisekelo, bese usebenzisa i-Pu oil-resistant oil sealing primer cj-104y ukuvimbela ngempumelelo into emhlophe yefilimu yopende. Isibonelo, i-teak, i-acid branch kanye nephayini ephethe amafutha kudinga ukunakwa okukhethekile.

2. Ukuvalwa kwezinto eziyisisekelo ezivamile: sicela usebenzise i-primer yokuvala ye-sr-201 noma ye-cj-104 ukuqinisekisa umphumela wokuvala.

3. Akukhuthazwa ukusebenzisa i-primer evamile njenge-sealer ukuvala i-substrate ngemva kokuyixuba, ngaphandle kwalokho, ukusebenza kokuvala akwanele, okungabangela ukuthi ifilimu yopende yakamuva icwile, njll. Ngaphezu kwalokho, i-ejenti yokwelapha ngobuningi ayikwazi ukusetshenziswa ngokuthanda kwayo ukugwema ukuthinta ukukhanya kwengubo ephezulu, iphunga lefilimu yopende, ubuningi bokuxhumanisa kwefilimu yopende akwanele, noma ifilimu yopende iyaqhekeka, iqhekekile, njll.; i-bulk diluent ingabangela ukuthi iphunga lefilimu yopende lihlale likhulu, i-gloss ayivunyelwe, futhi ithinte ukucaca kwefilimu yopende, njll.

4. Uma kusetshenziswa i-putty ekwakheni, akufanele iklwejwe futhi imbozwe ibe nkulu kakhulu, futhi kumele ipholishwe kahle ngemva kokumiswa ngokuphelele, ikakhulukazi enkambisweni yokupenda eqinile, ukuvimbela ukuqhekeka nokuwa.

5. Ukwembozwa okujiyile kanye kuphela akuvunyelwe ngokuphelele ngesikhathi sokwakhiwa kwendiza ukuvimbela ifilimu ukuthi ingangeni enkungwini kanye nokuthi indawo yayo yome.
