Ukwakhiwa kwepeyinti ye-PU kwiindawo zobusika:

I. indawo yokwakha

Ubushushu bendawo yokwakha abuyi kuba ngaphantsi kwe-5 ℃, kwaye ukufuma akuyi kuba ngaphezulu kwe-80%.

Xa ubushushu bangaphakathi buphantsi kwe-10 ℃, kucetyiswa ukuba kuthathwe amanyathelo afanelekileyo okufudumeza ukuqinisekisa isantya sokomisa ipeyinti ye-PU ngaphandle kokuchaphazela ukusebenza kakuhle kwemveliso.

II. Ukukhethwa kwemveliso

1. Iimveliso mazikhethwe ngokwexesha lonyaka. Ngokubanzi, ipeyinti yePu yahlulwe ngokwendlela yokusetyenziswa ehlotyeni kunye nendlela yokusetyenziswa ebusika. Kwileyibhile yesatifikethi sokuthobela imithetho (S) kukho indlela yokusetyenziswa ehlotyeni kwaye (D) kukho indlela yokusetyenziswa ebusika. Ukuba akunjalo, kuthetha ukuba yonke into iyasebenza. Ingakumbi kwiimveliso ze-PU top coat, ekwindla nasebusika, iimveliso zasehlotyeni aziyi kusetyenziswa, kungenjalo i-gloss inokuba rhabaxa;

2. I-arhente yokunyanga ye-Pu ehambelanayo kufuneka isetyenziswe kwipeyinti ye-PU, ingakumbi kwi-PU primer, i-arhente yokunyanga enomxholo oqinileyo omncinci ayifanele isetyenziswe ngokuthanda kwayo, kungenjalo iya kukhokelela ekungoneli kokuqina, ivumba elikhulu eliseleyo, ukusika ngaphantsi, ukugoba kwefilimu yepeyinti, ukukhazimla okungachanekanga okanye ubunzima obuphantsi bepeyinti yokugqiba, njl.njl.;

4. Ukukhetha isinyibilikisi:

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

Xa ubushushu buphantsi kwe-15 ℃, kukhethwa i-Pu winter diluent cj-003l okanye i-sr-73.

III. ukuxuba ipeyinti

1. Ngenxa yobushushu obuphantsi ebusika, isantya sokuphendula phakathi kwepeyinti ephambili yePu kunye ne-agent yokunyanga siyacotha. I-arhente yokunyanga engaphezulu eyi-10% ingongezwa kwindawo ukuze kuphuculwe ubulukhuni kunye nokunamathela kosuku olulandelayo, oku akuyi kuchaphazela ukukhazimla kwe-top coat. I-primer ingoma ngokukhawuleza.

2. Ebusika, ukongezwa kwe-ejenti yokunyanga kwi-PU clear primer akumele kudlule i-20% ubuncinci, kwaye kwi-white primer akumele kudlule i-10%. Musa ukongeza i-ejenti yokunyanga ngokuthanda kwakho ukuphucula isantya sokomisa, kungenjalo inokuthi iqhekeke, ingabi nancasa, ipeyinti ebuthathaka, ukuba mhlophe kamva kunye nezinye iimeko.

3. Emva kokulungiswa kwe-Pu primer kunye ne-finish coat, kufuneka zisetyenziswe ziphele kwiiyure ezi-3-4 (ngaphandle kwesiseko esimhlophe, kufuneka ziphele kwiiyure ezi-2).

IV, abanye

1. Kwizinto ezisisiseko ezinomthamo ophezulu weoyile okanye ukufuma, kuyimfuneko ukulawula umxholo wokufuma womthi nge-8-12%, emva koko uvale izinto ezisisiseko, kwaye usebenzise i-Pu oil-resistant sealing primer cj-104y ukuthintela ngempumelelo into emhlophe yefilimu yepeyinti. Umzekelo, i-teak, i-acid branch kunye ne-oil-bearing pine zifuna ingqwalasela ekhethekileyo.

2. Ukutywinwa kwezinto ezisisiseko eziqhelekileyo: nceda sebenzisa i-sr-201 okanye i-cj-104 sealing primer ukuqinisekisa isiphumo sokutywinwa.

3. Akukhuthazwa ukusebenzisa i-primer eqhelekileyo njenge-sealer ukuvala i-substrate emva kokuxuba, kungenjalo ukusebenza kokutywina akwanelanga, okunokubangela ukuba ifilimu yepeyinti yamva nje izike, njl. Ngaphezu koko, i-bulk curing agent ayinakusetyenziswa ngokuthanda kwayo ukuthintela ukuphazamisa ukukhanya kwe-top coat, ivumba lefilimu yepeyinti, uxinano oludibanisayo lwefilimu yepeyinti alwanelanga, okanye ifilimu yepeyinti iqhekekile, iqhekekile, njl.; i-bulk diluent inokubangela ukuba ivumba lefilimu yepeyinti lihlale likhulu, i-gloss ayivumelekanga, kwaye ichaphazele ukucaca kwefilimu yepeyinti, njl.

4. Ukuba i-putty isetyenziswa ekwakheni, ayizukukrwelwa kwaye igqunywe kakhulu, kwaye kufuneka ipholishwe kakuhle emva kokuba yomile ngokupheleleyo, ingakumbi kwinkqubo yokupenda eqinileyo, ukuthintela ukuqhekeka nokuwa.

5. Ukugquma okujiyileyo kube kanye akuvumelekanga ngokungqongqo ngexesha lokwakhiwa kweplani ukuthintela ifilimu ekungcoleni kwaye umphezulu ungomi.
