Waa maxay codsiyada surfactants ee dahaarka?

Surfactantswaa nooc ka mid ah xeryahooda oo leh dhismayaal molecular oo gaar ah kuwaas oo isku toosin kara is-dhexgalyada ama dusha sare, si weyn u beddelaya xiisadda dusha sare ama sifooyinka isdhexgalka. Warshadaha dahaarka, surfactants waxay door muhiim ah ka ciyaaraan codsiyada kala duwan, oo ay ku jiraan emulsification, qoynta, kala firdhisanaanta, foaming-ka, sinnaanta, saamaynta antistatic, iyo in ka badan, taas oo kor u qaadaysa xasilloonida, waxqabadka codsiga, iyo tayada ugu dambeysa ee dahaarka.

1.Emulsification

Dahaarka ku salaysan emulsion-ka (sida daaha-biyoodka), emulsifiers waa lama huraan. Waxay yareeyaan xiisadda isdhexgalka ee u dhexeeya wejiyada saliidda iyo biyaha, taas oo awood u siinaysa samaynta emulsions xasilloon oo ka soo jeeda qaybo aan la taaban karin. emulsifiers-yada caadiga ah waxaa ka mid ah surfactants anionic (tusaale, sodium dodecylbenzene sulfonate) iyo surfactants nonionic (tusaale, polyoxyethylene ethers).

2. Qooynta midabka iyo kala-firdhinta

Kala firdhinta isku midka ah ee midabada ku jira dahaarka waxay si toos ah u saameeyaan mugdiga, xasilloonida, iyo waxqabadka midabka. Waxyaalaha qoynta iyo kala firdhinta waxay yareeyaan xiisadda u dhaxaysa midabada iyo kuwa isku xidha, kor u qaadida qoynta isku midka ah iyo kala firdhisanaanta deggan iyada oo laga hortagayo qallafsanaanta iyo dejinta.

3.Xoojinta xumbo-samaynta iyo xakamaynta xumbo

Inta lagu jiro wax soo saarka iyo codsiga, dahaarka waxay u muuqdaan inay abuuraan xumbo, taas oo wax u dhimi karta muuqaalka filimka iyo waxqabadka. Foamers (tusaale, silikoon ku salaysan ama saliid macdaneed ku salaysan) waxay khalkhal geliyaan dhismayaasha xumbo, iyagoo yaraynaya samaynta xumbo iyo hubinta dusha dahaarka aan cillad lahayn.

4.Hagaajinta Heerka

Hantida siman ee daboolka ayaa go'aamisa jilicsanaanta iyo muuqaalka filimka la qalajiyey. Wakiilada heerka sare waxay ku shaqeeyaan laba hab oo asaasi ah:

• Yaraynta xiisadda dusha sare: Waxay xaqiijisaa xitaa ku faafta substrates, yaraynta cilladaha sida diirka liimiga ama dilaaca.

• Wax ka beddelka uumiga dareeraha: Waxay kordhisaa wakhtiga socodka, taasoo u oggolaanaysa dahaarka inuu si ku filan u simo ka hor inta aan la daaweyn.

5.Antistatic functionality

Qalabka elektiroonigga ah, baakadaha, iyo meelaha kale, dahaarka ayaa laga yaabaa inay ururiyaan kharashyo taagan sababtoo ah isqabqabsiga, oo keenaya khataro badbaado. Waxyaalaha lidka ku ah (tusaale, surfactants cationic) waxay soo saartaa qoyaanka deegaanka si ay u sameeyaan lakab korantada oogada dahaarka ah, fududaynta kala daadinta kharashka iyo yaraynta khataraha korantada.

6. Ilaalinta antimicrobial iyo Fungicidal

Deegaannada qoyan, dahaarka waxay u nugul yihiin koritaanka microbial, taasoo keentay hoos u dhaca filimka. Dawooyinka lidka ku ah bakteeriyada iyo fungicidal (tusaale, xeryahooda ammonium quaternary) waxay joojiyaan faafinta microbial, kordhinta nolosha shelf iyo adkeysiga adeegga ee daaha

7. Kobcinta dhalaalaysa iyo hagaajinta sibidhka

Dahaarka qaarkood waxay u baahan yihiin dhalaal sare ama sagxad siman (tusaale, alaabta guriga ama dahaarka warshadaha). Kor-u-qaadayaasha dhaldhalaalka ah iyo waxyaabaha lagu daro (tusaale, waxes ama silikoon) waxay wanaajiyaan milicsiga filimka waxayna yareeyaan khilaafka dusha sare, kor u qaadida caabbinta xirashada iyo sifooyinka taabashada.

Surfactants waxay u adeegaan doorar badan oo ka mid ah warshadaha dahaarka, laga bilaabo wanaajinta waxqabadka habaynta ilaa kor u qaadida sifooyinka filimka ugu dambeeya, dhammaantood waxay ka faa'iidaystaan awoodahooda nidaaminta wajiga gaarka ah. Iyada oo la horumarinayo dahaarka-saaxiibtinimo iyo waxqabad sarreeya, sheeko cusub, hufan, iyo surfactants-hooseeya ayaa sii ahaan doona diiradda muhiimka ah ee cilmi-baarista tignoolajiyada dahaarka mustaqbalka.
