DoorkaWakiilka kala firdhiya MFwaa in la dhimo wakhtiga iyo tamarta loo baahan yahay si loo dhamaystiro habka kala firdhinta, xasilinta kala firdhisanaanta midabka, wax ka beddelka sifooyinka dusha sare ee qaybaha midabka, hagaajinta dhaqdhaqaaqa qaybaha midabka, iwm.
Waxay ka kooban tahay dhinacyada soo socda:
Yaree wakhtiga iyo tamartaWakiilka kala firdhiya MFhabka
Iyada oo loo marayo isku-xidhnaanta, dusha sare ee qaybaha midabada ayaa si dhakhso ah looga beddeli karaa "interface gaas adag" loona beddelo "interface dareeraha adag". Sidaas darteed hoos u dhigida wakhtiga iyo tamarta looga baahan yahay shiididda.
Iska yaree viscosity
Codsiga kala firdhiyey wuxuu yarayn karaa viscosity iyo kordhinta awoodda loading ee midabka.
Kahortagga qulqulka oo ku soo noqo mid qallafsan
Ku kala firdhisan dusha midabka, iyada oo loo marayo dib-u-celinta elektrostatic ama caqabado adag si looga fogaado soo jiidashada wadajirka ah oo u dhow, si loo kordhiyo xasilloonida nidaamka.
Waxaa habboon in la sheego in qaybaha midabka midabka leh, ay ka weyn yihiin aagga dusha sare, tamarta sare ee korka, baahida loo qabo xoogga xayeysiiska sare eeWakiilka kala firdhiya MF, sidaas darteed qadarka kala-baxa ayaa sidoo kale la xidhiidha tayada koollada.
Ka hortag timaha sabeynaya
Si la mid ah mabda'a sare, waa nuxurka xasilloonida kala firdhisan.
Hagaajinta waxqabadka midabka
Hagaajinta awoodda midabaynta, kordhiso muujinta midabka. Kor u qaadida qoyaanka iyo hufnaanta ee midabada organic, iyo in la kordhiyo awoodda qarinaya ee midabada aan organic.
Saamaynta waxqabadka filimka rinjiga
Dispersant kama tagi doono filimka rinjiga ka dib sameynta filimka, laakiin sida qayb joogta ah oo ka mid ah filimka rinjiga ayaa ku jira filimka rinjiga, ma laha saameyn yar oo ku saabsan waxqabadka filimka rinjiga.
Saamaynta caabbinta biyaha:
Laga soo bilaabo mabda'a ficilka ee kala firdhinta, nuxurka kala-baxa waa surfactant, oo leh sifooyinka amphiphilic. Sidaa darteed, kala-baxayaashu waxay si lama filaan ah u yeelan doonaan hydrophilic gaar ah, filimka rinjiga ayaa saameyn weyn ku leh caabbinta biyaha.
Sv-246h superdispersant biyaha ku salaysan waa badeecada hydrophobic la beddelay, filimku qalalan, ma saameyn doono filimka laftiisa iska caabbinta biyaha.
Saamaynta dhalaalka:
gloss ee dusha filimka rinjiga ayaa inta badan ka soo jeeda iftiinka iftiinka dusha filimka rinjiga, iyo xaaladda dusha waxay ku xiran tahay cabbirka qayb ka mid ah qayb kasta, iyo sidoo kale waafaqsan iyo gobolka qaybinta.
Kala firdhisanaanta, xasilloonida ayaa shaki la'aan ah caawimo weyn oo dhalaalaya filimka rinjiga. Laakiin sidoo kale waxay u baahan yihiin in la tixgeliyo firdhiyaha laftiisa iyo resin laftiisa waafaqid. Tusaale ahaan, SV-246H superdispersant-ku-salaysan biyaha waxay leedahay waafaqid aad u wanaagsan nidaamyada akril ee biyaha ku salaysan, waxayna ku kordhin kartaa dhalaalka 2-3% marka loo eego kala firdhisyada caadiga ah sida 755W iyo 190.
gunaanad
Kala-saarku waa wax aad u muhiim ah oo lagu daro dahaarka.
Ma aha oo kaliya ka duwan filimka samaynta kaabayaal, xakamaynta pH ayaa isbeddeli doonta habka qalajinta; Waxa kale oo ay ka duwan tahay wakiilka qoynta, wakiilka xumbo-baxa iyo wakiilka dhumucda.
Sababtoo ah had iyo jeer waxay ku jirtaa filimka rinjiga oo ay leedahay maaddo sare, waxay saameyn weyn ku leedahay waxqabadka filimka rinjiga. Sidaa darteed, xulashada iyo isticmaalka kala-firdhinta ayaa caawinaad weyn u leh waxqabadka daahan.
