Bir k\u00f6p\u00fck \u00f6nleyici madde, ancak s\u0131v\u0131 taraf\u0131ndan tam olarak kabul edilmedi\u011finde i\u015fe yarar. Bu, bitmi\u015f bir teneke kutu yerine k\u00f6p\u00fck olu\u015fumunu izlemeden \u00f6nce kula\u011fa ters gelebilir. Bu \u00fcr\u00fcnleri tek bir noktadan de\u011ferlendiririm: iki kabarc\u0131k aras\u0131ndaki ince duvar. Katk\u0131 maddesi s\u0131v\u0131n\u0131n i\u00e7inde \u00e7\u00f6z\u00fcnm\u00fc\u015f halde kal\u0131rsa, o duvara asla ula\u015fmaz. \u015eiddetle reddedilirse, damlac\u0131klar olu\u015fturur ve \u00e7ukurlar b\u0131rak\u0131r. Yararl\u0131 s\u0131n\u0131flar, bu iki ba\u015far\u0131s\u0131zl\u0131k aras\u0131ndaki dar \u015feritte yer al\u0131r.<\/p>\n
K\u00f6p\u00fck, y\u00fczey aktif maddelerin hava-su aray\u00fcz\u00fcnde birikerek filmin esnekli\u011fini korumas\u0131 sayesinde kal\u0131c\u0131 olur. Hava, bir \u00e7\u00f6z\u00fcc\u00fc disk, bir pompa, bir p\u00fcsk\u00fcrtme tabancas\u0131 veya bir havaland\u0131rma havuzundan s\u00fcrekli olarak gelir. K\u00f6p\u00fck \u00f6nleyici damlac\u0131k, bu filme girmeli, \u00fczerinde yay\u0131lmal\u0131 ve s\u0131v\u0131n\u0131n ak\u0131p kabarc\u0131\u011f\u0131n \u00e7\u00f6kmesi i\u00e7in zay\u0131f bir k\u00f6pr\u00fc b\u0131rakmal\u0131d\u0131r. \u0130\u00e7eri girme ve yay\u0131lma i\u00e7in, k\u00f6p\u00fcren s\u0131v\u0131ya g\u00f6re daha d\u00fc\u015f\u00fck bir y\u00fczey gerilimi ve bu s\u0131v\u0131 i\u00e7inde zay\u0131f bir \u00e7\u00f6z\u00fcn\u00fcrl\u00fck gerekir. \u0130\u015fin s\u0131rr\u0131 budur. Polidimetilsiloksan\u0131n y\u00fczey gerilimi, 72 mN\/m olan suya kar\u015f\u0131 yakla\u015f\u0131k 20 mN\/m'dir, bu nedenle yay\u0131lmas\u0131 zordur. Bir\u00e7ok em\u00fclsiyondaki hidrofobik silika ise bir i\u011fne gibi davranarak filmin y\u0131rt\u0131lmas\u0131n\u0131 tamamlar. Hidrofobik par\u00e7ac\u0131klar i\u00e7eren mineral ya\u011f k\u00f6p\u00fck \u00f6nleyicileri, ayn\u0131 i\u015fi daha yava\u015f bir \u015fekilde yerine getirir. Polieter t\u00fcrleri genellikle s\u0131cakl\u0131\u011fa ba\u011fl\u0131d\u0131r: so\u011fukken daha sakin kal\u0131rlar, bulan\u0131kl\u0131k noktalar\u0131na yakla\u015ft\u0131klar\u0131nda \u00e7\u00f6z\u00fcn\u00fcrl\u00fcklerini kaybederler ve ancak o zaman aray\u00fcze yerle\u015firler.<\/p>\n
Laboratuvar kaplar\u0131 bunu gizler. \u00c7alkalama testi, h\u0131zl\u0131 \u00e7\u00f6kmeyi \u00f6d\u00fcllendirir. Sirk\u00fclasyon hatt\u0131 ise kesme, \u0131s\u0131 ve bir g\u00fcnl\u00fck pompalama sonras\u0131nda h\u00e2l\u00e2 mevcut olan damlac\u0131klar\u0131 \u00f6d\u00fcllendirir. Fazla em\u00fclgat\u00f6r kullan\u0131m\u0131, k\u00f6p\u00fck \u00f6nleyicinin form\u00fclde \u201ciyi\u201d g\u00f6r\u00fcnmesine neden olurken, k\u00f6p\u00fck \u00fczerinde etkisiz kalmas\u0131na yol a\u00e7ar. \u00c7ok az em\u00fclgat\u00f6r kullan\u0131lmas\u0131 veya yanl\u0131\u015f silikon se\u00e7ilmesi durumunda, kurumu\u015f kaplamada bal\u0131k g\u00f6z\u00fc efekti, ya\u011fl\u0131 bir pus veya \u0131slanmayan bir yeniden kaplama g\u00f6r\u00fcl\u00fcr. Ayn\u0131 hafta i\u00e7inde, ayn\u0131 re\u00e7ine sistemiyle her iki kusuru da gidermeye \u00e7al\u0131\u015ft\u0131m. Doz neredeyse hi\u00e7 de\u011fi\u015fmedi. De\u011fi\u015fen \u015fey uyumluluktu.<\/p>\n
Bu nedenle, su bazl\u0131 kaplamalarda katk\u0131 maddelerini ikiye ay\u0131r\u0131yorum. Bir k\u0131sm\u0131 \u00f6\u011f\u00fctme i\u015flemine kat\u0131l\u0131yor; \u00e7\u00fcnk\u00fc \u00f6\u011f\u00fct\u00fcc\u00fc hava olu\u015fturur ve iri damlac\u0131klar\u0131 filmin tolere edebilece\u011fi boyuta indirger. Bir k\u0131sm\u0131 ise viskozite artmaya ba\u015flad\u0131\u011f\u0131nda ortaya \u00e7\u0131kan mikro k\u00f6p\u00fc\u011f\u00fc yakalamak i\u00e7in seyreltme a\u015famas\u0131na ekleniyor. Ka\u011f\u0131t \u00fczerinde, son a\u015famada bir miktar ilave etmek verimli g\u00f6r\u00fcnebilir. Ancak bu, sertle\u015fmekte olan filmde minik kabarc\u0131klar\u0131n hapsolmas\u0131na neden olur. Proses suyu konusunda da ayn\u0131 mant\u0131k ge\u00e7erlidir, sadece birimlerde farkl\u0131l\u0131k vard\u0131r: Sabit bir \u015fekilde birka\u00e7 on ppm'lik bir ilave, genellikle k\u00f6p\u00fck tank\u0131na panik i\u00e7inde yap\u0131lan bo\u015falt\u0131mdan daha etkilidir.<\/p>\n
Bir saatlik sirk\u00fclasyondan sonra kal\u0131c\u0131l\u0131k kayboldu\u011funda, ilk olarak dozaj\u0131 art\u0131rm\u0131yorum. Hidrofobun uyumlu hale gelip gelmedi\u011fini, pH'\u0131n em\u00fclsiyonu bozup bozmad\u0131\u011f\u0131n\u0131 veya \u00fcr\u00fcn\u00fcn sadece y\u00fczeydeki k\u00f6p\u00fc\u011f\u00fc yok etmek i\u00e7in mi \u00fcretildi\u011fini, k\u00fctle i\u00e7indeki mikro k\u00f6p\u00fc\u011f\u00fc yok etmek i\u00e7in de\u011fil mi \u00fcretildi\u011fini sorgular\u0131m. Zaten \u00e7\u00f6z\u00fcnm\u00fc\u015f bir \u00fcr\u00fcnde dozu art\u0131rmak, y\u00fczey kusurlar\u0131na yol a\u00e7arken k\u00f6p\u00fc\u011f\u00fc de ortadan kald\u0131rmamak demektir.<\/p>\n
Dolay\u0131s\u0131yla teknik soru, \u201changi k\u00f6p\u00fck \u00f6nleyici en g\u00fc\u00e7l\u00fcd\u00fcr\u201d de\u011fil. As\u0131l soru, damlac\u0131\u011f\u0131n filmi bulmaya devam edebilmesi i\u00e7in yeterince uzun s\u00fcre hafif\u00e7e y\u00fczeyde kal\u0131p kalamayaca\u011f\u0131d\u0131r.

How Antifoaming Agent Control Foam at the Interface An antifoaming agent only works if the liquid does not fully accept it. That sounds backwards until you watch a foam film instead of a finished can. I judge these products from one place: the thin wall between two bubbles.
