imikhiqizo

impahla yamakhemikhali

Ngokwesakhiwo samakhemikhali ahlukile, lolu hlobo lwe-ejenti yokulinganisa lunezigaba ezintathu eziphambili: acrylic acid, i-organic silicon ne-fluorocarbon. Umenzeli we-Leagering ungumhlinzeki ojwayelekile osetshenziswa ngokusobala, ongenza ifilimu yokuhlanganisa imali ethambile, ebushelelezi futhi efanayo nenqubo yokoma. Inganciphisa ngempumelelo ukungezwani kobuso be-coatium, thuthukisa izinga layo kanye nokufana kwesigaba sezinto. Kungathuthukisa ukubhekelwa kwesixazululo sokuqeda, kunciphise amathuba okuba amabala nokumakwa lapho kuxubha, kukhulisa ukumboza, bese wenza umfaniswano wefilimu futhi wemvelo. Ikakhulukazi ama-surfactants, izixazululo ze-organic nokunye. Kunezinhlobo eziningi ze-ejenti yokulinganisa, kanye nezinhlobo ze-ejenti ezisetshenziswayo ezitsheni ezahlukahlukene azifani. I-SolVents ephakeme ye-SolS noma i-Butyl cellulose ingahle isetshenziswe emaphepheni asuselwa ku-solvent. Emanzini - Umenzeli osuselwa kokuqeda nge-surfcactants noma i-polyacrylic acid, i-carboxymethyl cellulose

Ukwethulwa komkhiqizo nezici

Ama-ejenti wokulinganisa ahlukaniswa kakhulu izigaba ezimbili. Eyokuqala ngokushintsha i-viscosity yefilimu kanye nesikhathi sokusebenza ukuze sisebenze, lolu hlobo lwe-ejenti lokulinganisa ikakhulukazi ezinye zezinto ezibilayo eziphakeme ze-organic sols noma izixube, njenge-isoporone, diacesone, i-solvesso150; Okunye ukuguqula izakhiwo ezingaphezulu kwefilimu zisebenze, abantu abajwayelekile bathi ukukhuphuka kwe-ejenti kubhekisele kulolu hlobo lwe-ejenti ye-level. Lolu hlobo lwe-ejenti lokufuduka lufudukela ebusweni befilimu ngokuhambisana okunomkhawulo, kuthinta izakhiwo ezingaphezulu kwefilimu ezifana nokungezwani kwezokuxhumana, futhi kwenza ifilimu ithole izinga elihle.

umsebenzi

Umsebenzi oyinhloko wokuhlobisa umhlobiso nokuvikelwa, uma kukhona ukugeleza nokulima okudala, akugcini ngokuthinta ukubukeka, kepha futhi kulimaza umsebenzi wokuvikela. Njengokwakheka kweShrinkage okubangelwa ubukhulu befilimu akwanele, ukwakheka kwama-mainholes kuzoholela ekunciphisweni kwefilimu, lokhu kuzonciphisa ukuvikelwa kwamafilimu. Enqubweni yokwakhiwa kwe-coating kanye nokwakhiwa kwamafilimu, kuzoba nezinguquko ezithile zenyama nangamakhemikhali, lezi zinguquko kanye nohlobo lokuhlanganisa ngokwalo, kuzokuthinta kakhulu ukugeleza kanye nokufakwa kwamandla okugobhoza.
Ngemuva kokuthi kusetshenziswe i-coating, kuzovela izindawo zokuxhumana ezintsha, ngokuvamile i-liquid / interface eliqinile phakathi kokuhlanganiswa kanye ne-substrate kanye ne-interface ebonakalayo ephakathi kwenhlanganisela kanye nomoya. Uma ukungezwani kwe-interfacial kwesikhombimsebenzisi esibonakalayo esiphakathi nendawo kanye ne-substrate kuphakeme kunokungezwani okubucayi komugqa we-substrate, ukunamathela ngeke kukhiqizwe ngokwemvelo, okuzokhiqiza amaphutha aphansi anjenge-fisheye kanye ne-shrinkage izimbobo.
Ukuhwamuka kwe-solvent ngesikhathi senqubo yokomisa yefilimu kuzoholela ekulweni kokushisa, ukuhlukunyezwa kanye nokwehluka kwengxabano ebusweni phakathi kobuso kanye nangaphakathi kwefilimu. Lo mehluko jikelele uholele ekunyakazweni kwesiyaluyalu ngaphakathi kwefilimu, wakha okuthiwa yiBenard Vortex. IBhenard Vortex iholela ekhasini le-orange; Kuzinhlelo ezinama-pigment angaphezu kweyodwa, uma kunomehluko othile ekuhambeni kwezinhlayiya ze-pigment, iBenard Vortex kungenzeka ukuthi iholele kumbala ontantayo nezinwele, futhi ukwakhiwa okuthe mpo kuzoholela emigqeni kasilika.
Inqubo yokomisa yefilimu yokupenda kwesinye isikhathi ikhiqiza izinhlayiya ezithile ze-collouble colloidal, ukukhiqizwa kwezinhlayiya ze-colloidal ze-insoluble kuzoholela ekwakhekeni kwengxabano yengxabano, okuvame ukuholela ekukhiqizweni kwezimbobo ze-shrinka. Isibonelo, ohlelweni lokuhlanganisa ngokuxhumeka, lapho ukwakhiwa kuqukethe ama-resin angaphezu kweyodwa, ama-resin ancibilikayo angenayo angakha izinhlayiya ze-colloidal ze-insoluble njengoba i-solvent inamathela ngesikhathi senqubo yokomisa yefilimu yokomisa. Ngaphezu kwalokho, ekwakhekeni okuqukethe i-sursuanting, uma i-surving ingahambelani nohlelo, noma inqubo yokomisa ngokuzithandela kwe-solvent, izinguquko zayo zokuhlushwa ziholela ekushintsheni kwe-solubity, ukwakheka kwamaconsi angahambelani, kuzokwenza futhi indawo ukungezwani. Lokhu kungaholela ekwakhekeni kwezimbobo ze-shrinkage.
Esezinhlelweni zokwakhiwa kwe-coation kanye nokwakhiwa kwamafilimu, uma kukhona ukungcola kwangaphandle, kungahle kuholele emgodini we-shrinkage, i-fisheye kanye nezinye iziphambeko zokulinganisa. Lokhu kungcola kuvame ukusuka emoyeni, amathuluzi okwakha kanye no-substrate uwoyela, uthuli, inkungu yokupenda, umphunga wamanzi, njll.
Izakhiwo zopende uqobo, njengokuvunywa kokwakha, isikhathi sokusoma, njll. I-viscosity ephezulu kakhulu yokwakha futhi isikhathi esifushane sokusoma ngokuvamile sivame ukukhiqiza indawo ephezulu yokufinyelela.
Ngakho-ke, kuyadingeka ukwengeza i-ejenti yokulinganisa, ngokusebenzisa ukunamathela kwinqubo yokwakhiwa kokwakhiwa kanye nokwakhiwa kwamafilimu kwezinguquko ezithile kanye nezinto zokuhlanganisa ukuze uguqule, ukusiza ukupenda ukuluma kahle.

iphakheji nokuhamba

B. Lo mkhiqizo ungasetshenziswa, 25kg, 200kg, ama-1000kg Barrels.
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
