Ngokushintsha kwesimo sezulu, futhi inkathi yokuqala yehlobo iyeza, inkinga yokwenziwa mhlophe kwefilimu kapende yaqala ukuvela futhi! Ngakho-ke, yiziphi izizathu zokuba mhlophe kwefilimu kapende? Kunezici ezine eziyinhloko: umswakama we-substrate, indawo yokwakha, nokwakhiwa. Inqubo kanye nama-coatings.
Okokuqala, okuqukethwe kwe-substrate umswakama
1. Izinguquko kumswakama we-substrate ngesikhathi sokuthutha
Isikhathi sokumisa sefilimu kapende sifushane, ukuhwamuka kwamanzi kuthatha isikhathi eside, umswakama ovela ku-veneer awukwazi ukuchichima ifilimu yepende ngenxa yokuvinjelwa kwefilimu kapende, futhi amanzi azoqoqa inani elithile, futhi umehluko kunkomba ye-refractive yamanzi kanye nenkomba ye-refractive yefilimu yepende ibangelwa. Ifilimu kapende imhlophe.
2. Izinguquko kumswakama we-substrate ngesikhathi sokugcinwa
Ngemuva kokuthi upende usungulwe ukuze wenze ifilimu yokupenda, umswakama ongaphansi kwe-substrate uyancipha kancane kancane, futhi isikhwama esincane senziwe efilimu kapende noma phakathi kwefilimu kapende kanye ne-substrate ukwenza ifilimu kapende ibe mhlophe.
Okwesibili, indawo yokwakha
1. Isimo sezulu
Ezimweni zokushisa eziphakeme, ukumuncwa kokushisa okubangelwa ukuhwamuka okusheshayo kwe-diluent phakathi nenqubo yokumboza kungase kubangele ukuba umhwamuko wamanzi osemoyeni uhlangane kupende futhi wenze ifilimu kapende ibe mhlophe; endaweni yomswakama ophezulu, ama-molecule amanzi azonamathela ebusweni bopende. Ngemva kokufafaza, amanzi ayashintshashintsha, okwenza ifilimu ibe nenkungu futhi ibe mhlophe.
2. Indawo yefekthri
Izitshalo ezahlukene zisezindaweni ezahlukene. Uma ziseduze nomthombo wamanzi, amanzi azohwamuka aye emoyeni ukuze enze umhwamuko wamanzi osemkhathini ube mkhulu, okuzokwenza ifilimu kapende ibe mhlophe.
Okwesithathu, inqubo yokwakha
1, izigxivizo zeminwe nokujuluka
Ekukhiqizeni kwangempela, ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza, abasebenzi abalindi ukuthi upende lome ngemva kokufafaza i-primer noma i-topcoat. Uma isisebenzi singawagqoki amagilavu, ukuthintana nebhodi lopende kuzoshiya uphawu, okuzophumela ekubeni mhlophe kopende.
2. I-compressor yomoya ayikhishelwa njalo
I-compressor yomoya ayikhishwa njalo, noma ukungasebenzi kahle kwesihlukanisi samanzi samafutha, futhi umswakama ungeniswa kupende, okwenza kube mhlophe. Ngokusho kokubuka okuphindaphindiwe, lokhu kubomvu kukhiqizwa ngokushesha, futhi isimo esimhlophe siyanyamalala ngemva kokuba ifilimu kapende isomile.
3, isifutho sikhulu kakhulu
Ubukhulu be-primer ngayinye nejazi eliphezulu libalwa "kushumi". Umdwebo wesikhathi esisodwa uminyene kakhulu, futhi azikho izinhlamvu ezingaphezu kwezimbili noma ngaphezulu "eziyishumi" ezisetshenziswa ngokuhambisana ngokuqinile nemithethonqubo, okuholela emazingeni okuhwamuka kwe-solvent engahambisani nezingqimba zangaphakathi nangaphandle zefilimu kapende, okuholela ekwakhekeni kwefilimu okungalingani. wefilimu kapende, nokungafihli kwefilimu kapende kumpofu futhi kumhlophe. Ifilimu emanzi ewugqinsi ngokweqile yandisa isikhathi sokumisa, ngaleyo ndlela imunca umswakama osemoyeni ukuze ifilimu enamathelayo iqhume.
4, ukulungiswa okungalungile kwe-viscosity kapende
Uma i-viscosity iphansi kakhulu, ungqimba lwepende luncane, amandla okufihla ampofu, ukuvikela kubuthakathaka, futhi ubuso bonakaliswe kalula ukugqwala. Uma i-viscosity iphezulu kakhulu, indawo yokulinganisa ingase ibe mbi futhi ukushuba kwefilimu kungase kungalawuleki kalula.
5, i-ejenti yombala wamanzi yenza ifilimu kapende ibe mhlophe
I-ejenti yombala evame ukusetshenziswa isekelwe emanzini, futhi isikhathi sokumisa asifiki emahoreni angu-4 ngemva kokuqeda, okungukuthi, okunye ukufafaza kwenziwa. Ngemuva kokumisa, umswakama osele uzokwakha isikhwama esincane phakathi kwefilimu yepende kanye nefilimu yepende ngokunwetshwa kwesikhathi, futhi ifilimu yepende izovela kancane kancane ibe mhlophe ngisho namhlophe.
6, ukuze kube eyomile control imvelo
Isikhala sokumiswa sikhulu, ukuvala uphawu akukuhle, futhi izinga lokushisa le-air conditioner ngaphakathi kunzima ukulondoloza ku-25 °C, okungase kuholele kumkhiqizo omhlophe. Kwezinye izindawo zendlu eyomile, kunokukhanya kwelanga okuqondile, okukhuthaza ukumuncwa kokukhanya kwe-ultraviolet ngokhuni, ngaleyo ndlela kusheshiswe ukuwohloka kwesithombe sobuso bezinkuni, okuholela kalula kumkhiqizo omhlophe.
Okwesine, inkinga kapende ngokwawo
1, mncane
Amanye ama-diluent anephuzu lokubila eliphansi uma kuqhathaniswa, futhi ukushibilika kushesha kakhulu. Ukwehla kwezinga lokushisa ngokushesha kuyashesha kakhulu, futhi umhwamuko wamanzi ufinyela endaweni yefilimu kapende futhi awuhambisani futhi umhlophe.
Uma i-diluent ingasetshenziswa, kunento efana ne-asidi noma i-alkali esele, ezogqwalisa ifilimu kapende futhi ibe mhlophe ngokuhamba kwesikhathi. I-diluent inamandla anganele okuncibilika ukuze ibangele ukuthi inhlaka kapende ihlehle futhi ibe mhlophe.
2, i-ejenti yokumanzisa
Umehluko phakathi kwenkomba ye-refractive yomoya kanye nenkomba ye-refractive ye-powder ependeni inkulu kakhulu kunomehluko phakathi kwenkomba ye-refractive ye-resin kanye nenkomba ye-refractive ye-powder, okwenza ifilimu yepende ibe mhlophe. Inani elinganele le-ejenti yokumanzisa lizobangela ukunqwabelana okungalingani kwempushana kupende kanye nokuba mhlophe kwefilimu kapende.
3. Inhlaka
I-resin iqukethe ingxenye encibilika kancane, futhi lezi zingxenye ezincibilika kancane zenziwa ngendlela yama-amorphous microcrystals noma amasaka amancane ekushiseni okuphansi.
Isifinyezo sesixazululo:
1, inothi lokuqukethwe komswakama we-substrate
Izinkampani zefenisha kufanele zisebenzise imishini ekhethekile yokomisa kanye nenqubo yokomisa ukuze zilawule ngokuqinile ukulingana komswakama we-substrate.
2, imvelo ukwakhiwa unake
Lawula ngempumelelo izinga lokushisa nomswakama, uthuthukise indawo yokwakha, yeka umsebenzi wokufafaza lapho izinga lokushisa elimanzi liphezulu kakhulu, gwema umswakama womkhiqizo endaweni yokufafaza uphezulu kakhulu, indawo eyomile ikhanyiswa ukukhanya kwelanga, kanye nesenzakalo esimhlophe. itholakala ukuthi ilungiswe ngesikhathi ngemuva kokwakhiwa.
3. Amaphuzu okufanele uwanake ngesikhathi sokwakha
Umsebenzisi kufanele agqoke isembozo sencwadi, akakwazi ukusika amakhona, akakwazi ukuthwala ifilimu lapho ifilimu isomile, upende kufanele uhambisane ngokuqinile nesilinganiso sezithako, isikhathi esiphakathi kokuphindaphinda okubili asikwazi ukuba sifushane kunesicacisiwe. isikhathi, landela imithetho “ezacile futhi kaningi”.
Uma usebenza nge-compressor yomoya, uma ifilimu kapende itholakala ukuthi imhlophe, thatha izinyathelo ezisheshayo zokumisa ukusebenza kwesifutho futhi uhlole i-compressor yomoya.
4, ukusetshenziswa amaphuzu ngopende ukunakwa
I-diluent kufanele isetshenziswe ndawonye ukulungisa inani le-diluent eyengeziwe kanye nenani le-ejenti yokumanzisa nokuhlakaza.
