Ngokutshintsha kwemozulu, kunye nexesha lokuqala lasehlotyeni liza, ingxaki yokumhlophe kwefilimu yepeyinti yaqala ukubonakala kwakhona! Ngoko ke, ziziphi izizathu zokuba mhlophe kwefilimu yepeyinti? Kukho iinkalo ezine eziphambili: umthamo wokufuma we-substrate, indawo yokwakha, kunye nokwakhiwa. Inkqubo kunye neengubo.

Okokuqala, umxholo wokufuma we-substrate

1. Utshintsho kumxholo womswakama we-substrate ngexesha lokuthutha

Ixesha lokumisa ifilimu yepeyinti lifutshane, ukuphuphuma kwamanzi kuthatha ixesha elide, umswakama kwi-veneer awukwazi ukugqithisa ifilimu yepeyinti ngenxa yokuvalwa kwefilimu yepeyinti, kwaye amanzi aya kuqokelela kwisixa esithile, kwaye umahluko kwisalathiso esihlaziyiweyo samanzi kunye nesalathiso se-refractive sefilimu yepeyinti ibangelwa. Ifilimu yepeyinti imhlophe.

2. Utshintsho kumxholo wokufuma we-substrate ngexesha lokugcinwa

Emva kokuba ipeyinti yenziwe ifilimu yepeyinti, ukufuma kwi-substrate kuyancipha ngokuthe ngcembe, kwaye i-micro sac yenziwa kwifilimu yepeyinti okanye phakathi kwefilimu yepeyinti kunye ne-substrate ukwenza ifilimu yepeyinti ibe mhlophe.

Okwesibini, indawo yokwakha

1. Imo yezulu

Kwimeko yobushushu obuphezulu, ukufunxwa kobushushu okubangelwa kukuphuma komphunga okukhawulezayo kwe-diluent ngexesha lenkqubo yokugquma kunokubangela ukuba umphunga wamanzi usemoyeni ujiyane kwipeyinti kwaye wenze ifilimu yepeyinti ibe mhlophe; kwindawo yomswakama ophezulu, iimolekyuli zamanzi ziya kubambelela kumphezulu wepeyinti. Emva kokutshiza, amanzi ayaguquka, abangele ukuba ifilimu ibe yinkungu kwaye ibe mhlophe.

2. Indawo yomzi-mveliso

Izityalo ezahlukeneyo zikwizowuni ezahlukeneyo. Ukuba zikufuphi nomthombo wamanzi, amanzi aya kunyuka abe ngumphunga emoyeni ukuze enze umxholo womphunga wamanzi kwi-atmosfera ube mkhulu, nto leyo eya kubangela ukuba ifilimu yepeyinti ibe mhlophe.

Okwesithathu, inkqubo yokwakha

1, iminwe kunye nokubila

Kwimveliso yangempela, ukwenzela ukuba kuphuculwe ukusebenza kakuhle kwemveliso, abasebenzi abalindeli ukuba ipeyinti yome emva kokutshiza i-primer okanye i-topcoat. Ukuba umsebenzi akagqoki iiglavu, ukudibana nebhodi yepeyinti kuya kushiya uphawu, oluya kubangela ukuba ipeyinti ibe mhlophe.

2. Icompressor yomoya ayikhutshwa rhoqo

I-compressor yomoya ayichithwanga rhoqo, okanye i-oil-water-separator ukungasebenzi kakuhle, kwaye umswakama ungeniswa kwipeyinti, obangela ukuba mhlophe. Ngokoqwalaselo oluphindaphindiweyo, le blush iveliswa ngokukhawuleza, kwaye imeko emhlophe iyanyamalala emva kokuba ifilimu yepeyinti yomile.

3, isitshizi sishinyene kakhulu

Ubunzima be-primer nganye kunye neengubo eziphezulu zibalwa "kwishumi". Umzobo wexesha elinye unzima kakhulu, kwaye akukho ngaphezu kwesibini okanye ngaphezulu kweempawu "ezilishumi" ezisetyenziswa ngokungqongqo ngokuhambelana nemimiselo, okukhokelela ekungahambelani kwesantya sokunyuka komphunga we-solvent yemigangatho yangaphakathi nangaphandle yefilimu yepeyinti, okubangela ukubunjwa kwefilimu engalinganiyo. yefilimu yepeyinti, kunye nokucaca kwefilimu yepeyinti impofu kwaye imhlophe. Ifilim eshinyene ngokugqithisileyo iphinde yandise ixesha lokumisa, ngaloo ndlela ifunxa ukufuma okusemoyeni ukuze ibangele ukuba ifilimu yokugquma ibe namadyungudyungu.

I-4, ukulungiswa okungafanelekanga kwe-viscosity yepeyinti

Xa i-viscosity iphantsi kakhulu, uluhlu lwepeyinti luncinci, amandla okufihla ahluphekile, ukukhuselwa kubuthathaka, kwaye umphezulu wonakaliswa lula ngokugqwala. Ukuba i-viscosity iphezulu kakhulu, ipropati yokulinganisa inokuba ihlwempu kwaye ubukhulu befilimu abukwazi ukulawulwa lula.

I-5, i-ejenti yombala wamanzi ibangela ukuba ifilimu yepeyinti ibe mhlophe

I-ejenti yombala esetyenziswa ngokuqhelekileyo isekelwe kumanzi, kwaye ixesha lokumisa alikho kwiiyure ezi-4 emva kokugqiba, oko kukuthi, enye i-spraying yenziwa. Emva kokumisa, ukufuma okushiyekileyo kuya kwenza isikhwama esincinci phakathi kwefilimu yepeyinti kunye nefilimu yepeyinti kunye nokwandiswa kwexesha, kwaye ifilimu yepeyinti iya kubonakala imhlophe kwaye imhlophe.

6, ukuba ibe ulawulo lokusingqongileyo owomileyo

Isithuba sokumiswa sikhulu, ukutywinwa akulunganga, kwaye ubushushu be-air conditioner ngaphakathi kunzima ukuyigcina kwi-25 °C, enokukhokelela kwimveliso emhlophe. Kwezinye iindawo zendlu eyomileyo, kukho ilanga elithe ngqo, elikhuthaza ukufunxwa kokukhanya kwe-ultraviolet ngomthi, ngaloo ndlela kukhawulezisa ukuthotywa kwefoto yomphezulu womthi, okhokelela ngokulula kwimveliso emhlophe.

Okwesine, ingxaki yepeyinti ngokwayo

1, mncinci

Ezinye iidiluyi zinendawo yokubila esezantsi, kwaye ukuguquguquka kukhawuleza kakhulu. Ukuhla kweqondo lokushisa ngokukhawuleza ngokukhawuleza, kwaye umphunga wamanzi udibanisa ebusweni befilimu yepeyinti kwaye ayihambelani kwaye imhlophe.

Xa i-diluent ingasetyenziswanga, kukho into efana ne-asidi okanye i-alkali eseleyo, eya konakalisa ifilimu yepeyinti kwaye ibe mhlophe ngokuhamba kwexesha. I-diluent ayinayo amandla aneleyo okunyibilika okwenza ukuba intlaka yepeyinti iwa kwaye ibemhlophe.

2, iarhente yokumanzisa

Ukwahlula phakathi kwesalathisi somoya kunye nesalathisi esihlaziyiweyo sepowder kwipeyinti sikhulu kakhulu kunomahluko phakathi kwesalathisi se-refractive ye-resin kunye ne-refractive index of powder, ebangela ukuba ifilimu yepeyinti ibe mhlophe. Ubuninzi obunganeleyo be-ejenti yokumanzisa kuya kubangela ukuqokelelwa okungalinganiyo komgubo kwipeyinti kunye nokumhlophe kwefilimu yepeyinti.

3. Intlaka

I-resin iqulethe i-low-melting component, kwaye ezi zixhobo ezincibilikayo ezincibilikayo ziyancipha ngendlela ye-amorphous microcrystals okanye i-microscopic sacs kwiqondo lokushisa eliphantsi.

Isishwankathelo sesisombululo:

1, inqaku lokufuma kwi-substrate

Iinkampani zefenitshala kufuneka zisebenzise isixhobo esikhethekileyo sokumisa kunye nenkqubo yokomisa ukulawula ngokungqongqo ukulingana komswakama we-substrate.

2, indawo yokwakha ingqalelo

Lawula ngokufanelekileyo iqondo lobushushu kunye nokufuma, uphucule indawo yokwakha, yeka umsebenzi wokutshiza xa iqondo lobushushu elimanzi liphezulu kakhulu, kunqande ukufuma kwemveliso kwindawo yokutshiza kuphezulu kakhulu, indawo eyomileyo ikhanyiselwa kukukhanya kwelanga, kunye nesiganeko esimhlophe. ifunyenwe ukuba ilungiswe ngexesha emva kokwakhiwa.

3. Amanqaku okuqwalasela ngexesha lokwakha

Umsebenzisi kufuneka anxibe isigqubuthelo sencwadi, akakwazi ukunqumla iikona, akakwazi ukuthwala ifilimu xa ifilimu ingomile, ipeyinti kufuneka ihambelane ngokungqongqo nomlinganiselo wezithako, ixesha eliphakathi kokuphindaphinda ezimbini alikwazi ukuba lifutshane kunoko kuchaziweyo. ixesha, landela "ubhityile kwaye amaxesha amaninzi" imithetho.

Xa usebenza nge-compressor yomoya, ukuba ifilimu yepeyinti ifunyenwe imhlophe, thatha amanyathelo ngokukhawuleza ukumisa umsebenzi wokutshiza kwaye ukhangele i-compressor yomoya.

I-4, ukusetyenziswa kwamanqaku epeyinti yokuqwalaselwa

I-diluent kufuneka isetyenziswe kunye ukulungisa ubungakanani be-diluent eyongeziweyo kunye nomthamo wokumanzisa kunye ne-arhente yokuchitha.
