Waa maxay codsiyada surfactants ee dahaarka?

Daawaynta hawadawaa nooc ka mid ah iskudhisyo leh qaab-dhismeedyo molecular gaar ah oo isku-habeyn kara is-dhexgalka ama dusha sare, taasoo si weyn u beddesha xiisadda dusha sare ama sifooyinka is-dhexgalka. Warshadaha dahaarka, surfactants-ku waxay door muhiim ah ka ciyaaraan codsiyada kala duwan, oo ay ku jiraan emulsification, qoynta, kala firdhinta, defoaming, leveling, antistatic effects, iyo waxyaabo kaloo badan, taasoo kor u qaadaysa xasilloonida, waxqabadka codsiga, iyo tayada kama dambaysta ah ee dahaarka.

1. Emulsification​

Dahaarka ku salaysan emulsion-ka (sida dahaarka biyaha laga soo saaro), emulsifiers-ku waa lama huraan. Waxay yareeyaan xiisadda u dhaxaysa wejiga iyo wejiga ee u dhaxaysa saliidda iyo biyaha, taasoo suurtogalinaysa sameynta emulsions deggan oo ka imanaya qaybaha aan la misixin. Emulsifiers-ka caadiga ah waxaa ka mid ah anionic surfactants (tusaale ahaan, sodium dodecylbenzene sulfonate) iyo nonionic surfactants (tusaale ahaan, polyoxyethylene ethers).

2. Qoynta iyo Kala-baxa Midabka

Kala firdhinta isku midka ah ee midabada ee dahaarka ayaa si toos ah u saamaysa daahnaanta, xasilloonida, iyo waxqabadka midabka. Walxaha qoynta iyo kala firdhinta waxay yareeyaan xiisadda wejiga ee u dhaxaysa midabada iyo waxyaabaha isku xidha, iyagoo kor u qaadaya qoynta isku midka ah iyo kala firdhinta xasilloon iyadoo ka hortagaysa isku-darka iyo degitaanka.

3. Ka saarista xumbo iyo xakamaynta xumbo

Inta lagu jiro wax soo saarka iyo codsiga, dahaarka ayaa u janjeera inuu soo saaro xumbo, kuwaas oo wax u dhimi kara muuqaalka filimka iyo waxqabadka. Xumbada (tusaale ahaan, ku salaysan silikoon ama saliid macdan ah) waxay khalkhal geliyaan qaab-dhismeedka xumbo, iyagoo yareynaya sameynta xumbo waxayna hubinayaan dusha sare ee dahaarka oo siman oo aan cillad lahayn.

4. Horumarinta heerarka

Sifada siman ee dahaarka ayaa go'aamisa simanaanta iyo muuqaalka filimka la qalajiyey. Walxaha siman waxay ku shaqeeyaan laba farsamo oo aasaasi ah:

• Yaraynta xiisadda dusha sare: Waxay hubisaa in si siman loogu faafo dusha sare, iyadoo la yareynayo cilladaha sida diirka liinta ama godadka.

• Wax ka beddelka uumi-baxa dareeraha: Waxay kordhisaa waqtiga socodka, taasoo u oggolaanaysa dahaarka inuu si ku filan u siman yahay ka hor inta uusan bogsan.

5. Shaqada ka hortagga istaroogga

Qalabka elektaroonigga ah, baakadaha, iyo meelaha kale, dahaadhku waxay ururin karaan kharashyo taagan sababtoo ah is jiidjiid, taasoo keenaysa khataro ammaan. Walxaha ka hortagga jeermiska (tusaale ahaan, walxaha ka hortagga jeermiska) waxay nuugaan qoyaanka deegaanka si ay u sameeyaan lakab gudbiye ah oo ku yaal dusha sare ee dahaarka, taasoo sahlaysa kala firdhinta dallacaadda iyo yareynta khataraha elektrostatic-ka.

6. Ilaalinta jeermiska dila iyo jeermiska

Deegaannada qoyan, dahaarka ayaa u nugul koritaanka bakteeriyada, taasoo keenta burburka filimka. Walxaha lidka ku ah bakteeriyada iyo fungicidal-ka (tusaale ahaan, isku-dhafka ammonium ee quaternary) waxay joojiyaan faafitaanka bakteeriyada, iyagoo dheereynaya cimriga kaydinta iyo cimriga adeegga dahaarka.

7. Horumarinta Iftiinka iyo Horumarinta Simbiriirixanka

Dahaadh gaar ah waxay u baahan yihiin dusha sare ee dhalaalaya ama siman (tusaale ahaan, alaabta guriga ama dahaarka warshadaha). Kobciyeyaasha dhalaalka iyo waxyaabaha lagu daro simbiriirixanka (tusaale ahaan, wax ama silikoon) waxay hagaajiyaan soo-jiidashada filimka waxayna yareeyaan is-jiidjiidka dusha sare, iyagoo kor u qaadaya iska caabbinta xirashada iyo sifooyinka taabashada.

Duufaanta waxay u adeegaan doorar badan warshadaha dahaarka, laga bilaabo hagaajinta waxqabadka habaynta ilaa kor u qaadista sifooyinka filimka ugu dambeeya, dhammaantoodna waxay ka faa'iidaystaan ​​​​awoodahooda gaarka ah ee habaynta is-dhexgalka. Iyadoo la horumarinayo dahaarka deegaanka u fiican iyo waxqabadka sare, dahaarka cusub, hufan, iyo sunta yar ayaa sii ahaan doona diiradda ugu weyn ee cilmi-baarista tignoolajiyada dahaarka mustaqbalka.
