\u0130ster boya kutusunda saklans\u0131n ister uygulama sonras\u0131 kurutma i\u015flemi s\u0131ras\u0131nda olsun, boya daha y\u00fcksek viskoziteye sahip oldu\u011funda k\u00f6p\u00fck giderme i\u015flemi daha zordur. Ger\u00e7ek \u00fcretimde, \u00e7\u00f6kme ve sarkmay\u0131 \u00f6nlemek i\u00e7in boyan\u0131n viskozitesi belirli bir aral\u0131kta kontrol edilmelidir. Su bazl\u0131 ah\u015fap kaplamalar\u0131n orta bas\u0131n\u00e7l\u0131 havas\u0131z p\u00fcsk\u00fcrt\u00fclmesi s\u0131ras\u0131nda, kaplaman\u0131n \u00e7al\u0131\u015fma viskozitesi 80 KU veya \u00fczerinde tutulmal\u0131d\u0131r; bitmi\u015f \u00fcr\u00fcn\u00fcn fabrika \u00e7\u0131k\u0131\u015f viskozitesi ise s\u0131cakl\u0131k art\u0131\u015flar\u0131n\u0131n neden oldu\u011fu viskozite de\u011fi\u015fikliklerini ve uygulama s\u0131ras\u0131nda viskozitenin su ile ayarlanmas\u0131 ihtiyac\u0131n\u0131 telafi etmek i\u00e7in genellikle 90 KU'nun \u00fczerinde tutulmal\u0131d\u0131r. Kaplaman\u0131n reolojik \u00f6zelliklerine ba\u011fl\u0131 olarak, viskozite genellikle 90 ila 120 KU (25\u00b0C) aras\u0131nda kontrol edilir.<\/p>\n

3. K\u00f6p\u00fck kesiciler<\/b><\/p>\n

Su bazl\u0131 y\u00fcksek viskoziteli mat verniklerde, y\u00fcksek re\u00e7ine i\u00e7eri\u011fi ve y\u00fcksek viskozite nedeniyle k\u00f6p\u00fck giderme daha zordur. \u00dcretim s\u0131ras\u0131nda kullan\u0131lan k\u00f6p\u00fck kesici miktar\u0131 ve t\u00fcr\u00fc nispeten y\u00fcksektir ve genellikle iki ila \u00fc\u00e7 k\u00f6p\u00fck kesici birlikte kullan\u0131l\u0131r ve bunlar y\u00fcksek h\u0131zl\u0131 dispersiyondan \u00f6nce, s\u0131ras\u0131nda ve sonras\u0131nda bast\u0131rmak, k\u00f6p\u00fck gidermek ve havas\u0131n\u0131 almak i\u00e7in kullan\u0131l\u0131r. K\u00f6p\u00fck kesici ve di\u011fer katk\u0131 maddelerinin re\u00e7ine ile iyi kar\u0131\u015fmas\u0131 i\u00e7in, \u00e7ok say\u0131da kabarc\u0131k olu\u015fturacak y\u00fcksek h\u0131zl\u0131 dispersiyon gereklidir. Bu nedenle, y\u00fcksek h\u0131zl\u0131 dispersiyondan \u00f6nce daha iyi k\u00f6p\u00fck giderici \u00f6zelliklere sahip belirli bir miktarda k\u00f6p\u00fck giderici eklemek gerekir.<\/p>\n

Su bazl\u0131 ah\u015fap kaplamalarda yayg\u0131n olarak kullan\u0131lan ana k\u00f6p\u00fck gidericiler mineral ya\u011f ve silikondur. \u0130lki d\u00fc\u015f\u00fck maliyetlidir ve zay\u0131f k\u00f6p\u00fck giderme kabiliyetine sahiptir. Esas olarak 85% ta\u015f\u0131y\u0131c\u0131 ya\u011f ve 15% hidrofobik partik\u00fcllerden olu\u015fur ve hidrofobik partik\u00fcller genellikle f\u00fcme silika, metal stearat vb. malzemelerden yap\u0131l\u0131r. Bu tip k\u00f6p\u00fck kesici, kaplama filminin kararmas\u0131na e\u011filimlidir ve d\u00fc\u015f\u00fck parlakl\u0131\u011fa sahip macun ve astarlarda kullan\u0131labilir. \u0130kincisi esas olarak, parlakl\u0131k ve \u015feffafl\u0131k \u00fczerinde \u00e7ok az etkisi olan g\u00fc\u00e7l\u00fc su itici organosilikon ve polieter modifiye polidimetilsiloksan em\u00fclsiyonlar\u0131ndan olu\u015fur. \u015eu anda su bazl\u0131 ah\u015fap kaplamalar i\u00e7in ana k\u00f6p\u00fck kesicidir. Bununla birlikte, baz\u0131 makaleler mineral ya\u011f ile modifiye edilmi\u015f baz\u0131 k\u00f6p\u00fck kesicilerin organosilikon k\u00f6p\u00fck kesicilerden daha etkili oldu\u011funu belirtmi\u015ftir. Bu nedenle k\u00f6p\u00fck kesicilerin se\u00e7imi farkl\u0131 re\u00e7inelere g\u00f6re yap\u0131lmal\u0131 ve deneysel sonu\u00e7lara g\u00f6re belirlenmelidir.<\/p>\n

4. K\u0131vamla\u015ft\u0131r\u0131c\u0131lar<\/b><\/p>\n

Su bazl\u0131 y\u00fcksek viskoziteli mat verniklerin \u00fcretiminde k\u0131vamla\u015ft\u0131r\u0131c\u0131 se\u00e7imi \u00e7ok \u00f6nemlidir. Bu, depolama veya uygulama s\u0131ras\u0131nda \u00fcr\u00fcn\u00fcn k\u00f6p\u00fck giderici \u00f6zelliklerinin anahtar\u0131d\u0131r. \u015eu anda, yayg\u0131n olarak kullan\u0131lan iki ana k\u0131vamla\u015ft\u0131r\u0131c\u0131 t\u00fcr\u00fc vard\u0131r: birle\u015ftirici ve alkali \u015fi\u015febilir. \u0130lki daha iyi ak\u0131\u015f ve kesme viskozitesi sa\u011flarken, ikincisi depolama stabilitesini ve sarkma \u00f6nleyici \u00f6zellikleri geli\u015ftirebilir. \u00dcretimde, birincisi k\u00f6p\u00fck giderme ve gaz giderme i\u00e7in elveri\u015fli iken, ikincisi k\u00f6p\u00fc\u011f\u00fc stabilize etmek i\u00e7in daha kolayd\u0131r. Bununla birlikte, birincisi daha iyi ak\u0131\u015fkanl\u0131\u011fa sahip oldu\u011fundan, uygulama s\u0131ras\u0131nda kirlenmeye kar\u015f\u0131 direnci b\u00fcy\u00fck \u00f6l\u00e7\u00fcde azal\u0131r. Bu nedenle, kaplaman\u0131n depolama stabilitesini korumak ve uygulama s\u0131ras\u0131nda daha iyi sarkma direnci ve kirlenme \u00f6nleme sa\u011flamak i\u00e7in, su bazl\u0131 mat verniklerin bazen viskozite y\u00fcksek olsa bile belirli bir alkali \u015fi\u015febilir k\u0131vamla\u015ft\u0131r\u0131c\u0131 ile birlikte kullan\u0131lmas\u0131 gerekir. Bu iki tip k\u0131vamla\u015ft\u0131r\u0131c\u0131n\u0131n bir\u00e7ok \u00e7e\u015fidi vard\u0131r ve re\u00e7ine se\u00e7ildikten sonra deneysel sonu\u00e7lara g\u00f6re bunlar\u0131n nas\u0131l e\u015fle\u015ftirilece\u011fi belirlenmelidir.<\/p>\n

5. Matla\u015ft\u0131r\u0131c\u0131 maddeler ve \u0131slat\u0131c\u0131 ve da\u011f\u0131t\u0131c\u0131 maddeler<\/b><\/p>\n

Orta bas\u0131n\u00e7l\u0131 havas\u0131z p\u00fcsk\u00fcrtmeli su bazl\u0131 matla\u015ft\u0131rma verniklerinde matla\u015ft\u0131rma maddesi olarak genellikle matla\u015ft\u0131r\u0131c\u0131 mum pastalar yerine matla\u015ft\u0131r\u0131c\u0131 maddeler se\u00e7ilir. Bunun ba\u015fl\u0131ca nedeni, orta bas\u0131n\u00e7l\u0131 havas\u0131z p\u00fcsk\u00fcrtmede y\u00fczey hissinin \u00e7ok \u00f6nemli olmamas\u0131 ve ayr\u0131ca k\u00f6p\u00fck giderme, fiyat ve sistem kal\u0131nla\u015ft\u0131rma hususlar\u0131d\u0131r. Matla\u015ft\u0131r\u0131c\u0131 vaks pastalar\u0131n\u0131n (tozlar) kullan\u0131m\u0131 nispeten pahal\u0131d\u0131r ve ayr\u0131ca da\u011f\u0131l\u0131m s\u0131ras\u0131nda k\u00f6p\u00fcrmeye e\u011filimlidir, bu da ortadan kald\u0131r\u0131lmas\u0131 zordur.<\/p>\n

Y\u00fcksek viskoziteli verniklerde, matla\u015ft\u0131r\u0131c\u0131 maddelerin \u00e7\u00f6kme \u00f6nleyici etkisi neredeyse \u00f6nemsizken, k\u00f6p\u00fck giderme \u00f6zellikleri \u00fczerindeki etkisi \u00e7ok \u00f6nemli hale gelir. Genel olarak, hidratlanm\u0131\u015f y\u00fczeylerin k\u00f6p\u00fckten ar\u0131nd\u0131r\u0131lmas\u0131, hidratlanmam\u0131\u015f olanlara g\u00f6re daha kolayd\u0131r ve d\u00fc\u015f\u00fck ya\u011f emilimine sahip y\u00fczeylerin k\u00f6p\u00fckten ar\u0131nd\u0131r\u0131lmas\u0131, y\u00fcksek ya\u011f emilimine sahip olanlara g\u00f6re daha kolayd\u0131r. Deneyler, \u0131slat\u0131c\u0131 ve da\u011f\u0131t\u0131c\u0131 madde se\u00e7iminin k\u00f6p\u00fck giderme \u00fczerinde \u00f6nemli bir etkisi oldu\u011funu g\u00f6stermi\u015ftir. Matla\u015ft\u0131r\u0131c\u0131 madde y\u00fczeyinin da\u011f\u0131t\u0131c\u0131 madde taraf\u0131ndan \u0131slat\u0131lmas\u0131 ne kadar iyi olursa, k\u00f6p\u00fck giderme i\u00e7in o kadar elveri\u015fli olur.<\/p>\n

6. \u00dcretim s\u00fcre\u00e7lerinin tasar\u0131m\u0131 ve kontrol\u00fc<\/b><\/p>\n

\u00dcretim s\u00fcre\u00e7lerinin tasar\u0131m\u0131 ve kontrol\u00fc de kaplama \u00fcretiminde \u00e7ok \u00f6nemlidir. Su bazl\u0131 kaplamalar\u0131n \u00fcretiminde, re\u00e7ine ve di\u011fer bile\u015fenlerin minimum kabarc\u0131k olu\u015fumuyla homojen bir \u015fekilde kar\u0131\u015fmas\u0131n\u0131 sa\u011flamak i\u00e7in uygun bir \u00fcretim s\u00fcrecinin form\u00fcle edilmesi ve s\u0131k\u0131 bir \u015fekilde kontrol edilmesi gerekir.<\/p>\n

\u00d6rne\u011fin, mat vernik \u00fcretiminde re\u00e7ine genellikle gerekli inceli\u011fe ula\u015f\u0131lana kadar katk\u0131 maddeleri ve matla\u015ft\u0131r\u0131c\u0131 maddelerle y\u00fcksek h\u0131zda kar\u0131\u015ft\u0131r\u0131l\u0131r. Bu i\u015flem s\u0131ras\u0131nda \u00e7ok say\u0131da kabarc\u0131k olu\u015facakt\u0131r. Viskozite d\u00fc\u015f\u00fck oldu\u011funda, bu kabarc\u0131klar genellikle 24 saat bekletildikten sonra kaybolacakt\u0131r. Ancak, viskozite y\u00fcksek ve sistem tiksotropik oldu\u011funda, bu kabarc\u0131klar\u0131n uzun bir s\u00fcre sonra bile ortadan kald\u0131r\u0131lmas\u0131 zor olacakt\u0131r. Bu durumda, matla\u015ft\u0131rma maddesinin bulama\u00e7 haline getirildikten sonra eklenmesi kabarc\u0131k olu\u015fumunu etkili bir \u015fekilde azaltabilir. \u00d6te yandan, k\u00f6p\u00fck kesiciler veya da\u011f\u0131lmas\u0131 kolay olmayan di\u011fer katk\u0131 maddeleri eklenirken, da\u011f\u0131lma i\u00e7in gereken h\u0131z\u0131 en aza indirmek ve homojen da\u011f\u0131lma i\u00e7in gereken s\u00fcreyi azaltmak i\u00e7in bunlar\u0131 seyreltmek ve da\u011f\u0131lm\u0131\u015f halde yava\u015f\u00e7a eklemek en iyisidir. Baz\u0131 mum pastalar\u0131 gibi k\u00f6p\u00fcrmeye e\u011filimli baz\u0131 katk\u0131 maddeleri m\u00fcmk\u00fcn oldu\u011funca ge\u00e7 d\u00fc\u015f\u00fck h\u0131zl\u0131 dispersiyon i\u015flemi s\u0131ras\u0131nda eklenmelidir.<\/p>\n

Sonu\u00e7<\/b><\/p>\n

Su bazl\u0131 ah\u015fap kaplamalar\u0131n y\u00fcksek viskozitesi, tek bir uygulaman\u0131n kal\u0131nl\u0131\u011f\u0131n\u0131 art\u0131rabilir, \u00fcretim verimlili\u011fini art\u0131rabilir ve uygulama s\u0131ras\u0131nda sarkma ve kabarc\u0131k olu\u015fumu olas\u0131l\u0131\u011f\u0131n\u0131 azaltabilir. Bununla birlikte, uygulama s\u0131ras\u0131nda k\u00f6p\u00fck gidermeyi daha zor hale getirir, bu da uygulama sonras\u0131 y\u00fczey etkisini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde etkiler ve su bazl\u0131 ah\u015fap kaplamalar\u0131n di\u011fer uygulama alanlar\u0131na yay\u0131lmas\u0131n\u0131 \u00f6nleyen \u00f6nemli bir engeldir. Su bazl\u0131 y\u00fcksek viskoziteli verniklerin k\u00f6p\u00fck giderme \u00f6zellikleri \u00fczerine yap\u0131lan ara\u015ft\u0131rmalarda, re\u00e7ine ve k\u0131vam artt\u0131r\u0131c\u0131lar\u0131n se\u00e7imi en \u00f6nemlisidir, bunu k\u00f6p\u00fck gidericilerin, matla\u015ft\u0131r\u0131c\u0131lar\u0131n ve di\u011fer katk\u0131 maddelerinin se\u00e7imi ve son olarak \u00fcretim s\u00fcrecinin optimizasyonu ve viskozitenin ayarlanmas\u0131 takip eder. \u0130yi bir \u00fcr\u00fcn sadece iyi fiziksel ve kimyasal \u00f6zelliklere de\u011fil, ayn\u0131 zamanda iyi uygulama \u00f6zelliklerine de sahip olmal\u0131d\u0131r.
