Kala firdhisanwaa surfactant leh laba sifo oo iska soo horjeeda, lipophilic iyo hydrophilic ee molecule. Waxaa loo isticmaali karaa in si isku mid ah loo kala firdhiyo walxaha adag ee aan organic iyo organic kuwaas oo ay adag tahay in ay ku milmaan dareeraha. Waxa kale oo loo isticmaali karaa si looga hortago sedimentation iyo agglomeration ee qayb adag si ay u sameeyaan ka joojinta xasilloon.

Surfactants Anionic ayaa inta badan ah kondensates sulfonic acid-formaldehyde oo leh nuklei caraf udgoon. Waxaa jira laba nooc oo ah naphthalene iyo phenol. Waxyaalaha kala firdhinta iyo heerka nafta-ku-salaysan sidawakiilada kala firdhiya NNO, MF, iwm.

Naftalaan
Naphthalene2

Tilmaamayaasha ugu muhiimsan eeKala firdhinta NNO:

Mashaariicda iyo tilmaamayaasha NNO
Awooda kala firdhiso ≥95%
Qiimaha PH (1% xal aqueous) 7-9
Waxyaabaha ku jira sulfate ≤18%
Waxyaalaha wasakhda ah ee aan milmi karin biyaha ≤0.05%
Naftalane3
Naftalane4

Farqiga iyo xidhiidhka ka dhexeeya kala firdhisanaanta NNO iyo MF?

Kala firdhiya NNO sodium methylene naphthalene sulfonate waxaa inta badan loo isticmaalaa sida kala firdhiso ee dheeh kala firdhiso, dheesha vatanka, midabada falgal, dheeha acid iyo maqaar, saamaynta shiidi aad u fiican, milmi iyo kala firdhiso; Waxa kale oo loo isticmaali karaa daabacaadda dunta iyo dheehidda, Cayayaanka qoyan waxaa loo isticmaalaa sida firdhiya, kala firdhiyaa warqad samaynta, daro electroplating, rinjiga biyaha milmaya, kala firdhiso midabka, wakiilada biyaha, kala firdhiso madow carbon, iwm. Dispersant NNO waxaa inta badan loo isticmaalaa warshadaha loogu talagalay dheeha rinji ee ganaaxa dheeha, dheeha leuco acid, iyo dheeha firidhsan iyo milma. Waxa kale oo loo isticmaali karaa midabaynta xariirta/dhogorta dharka isku xidhan, si aanu midab uga yeelan xariirka. Wakiilka firdhiya ee NNO waxaa inta badan loo isticmaalaa warshadaha dheeha sida gargaarka kala firdhisan ee firdhinta iyo wax soo saarka harooyinka, xasilloonida emulsion caag ah, iyo gargaarka haragga ah. Dispersant MF sodium methylene bis-methyl naphthalene sulfonate, formaldehyde condensate of sodium methyl naphthalene sulfonate, waa surfactant anionic ah, si fudud u milmay biyaha, fududahay in la nuugo qoyaan, non-holac, waxa uu leeyahay diffusivity aad u fiican iyo xasilloonida kulaylka Resistance, ma permeability iyo xumbo. caabbinta aashitada iyo alkali, biyaha adag iyo cusbada aan organic ahayn, oo aan u xidhnayn suufka, linenka iyo fiilooyinka kale; xidhiidhka ka dhexeeya borotiinka iyo fiilooyinka polyamide; waxaa loo isticmaali karaa surfactants anionic iyo nonionic isku mar , Laakiin laguma qasi karo dheeh cationic ama surfactants; Awoodda looga hortagayo kala firdhinta walxaha dheeha dheeha ee ka imanaya kulaylka ayaa ka fiican NNO. Waqtigan xaadirka ah, NNO-ga kala firdhiyey ee laga soo saaro guriga iyo dibedda ayaa leh wax qabad heerkul sarreeya oo hooseeya, midab khafiif ah laakiin aan heerkulka sare ahayn, iyo xasilloonida kulaylka ee ku saabsan 80 ℃; iyo in kasta oo xasilloonida iska caabbinta kulaylka ee kala firdhiyaa MF ay gaadho 130 ℃ 4 ilaa 5, laakiin Waa budo bunni ah oo aan loo isticmaali karin in lagu kala firdhiyo midabada iftiinka leh.

Naftalane6

Tilmaamayaasha ugu muhiimsan eeKala firdhiyey MF:

Mashaariicda iyo tilmaamayaasha MF
Awooda kala firdhiso ≥95%
Qiimaha PH (1% xal aqueous) 7-9
Waxyaabaha ku jira sulfate ≤5%
Dejinta kulaylka heerka 130°C 4-5
Waxyaalaha wasakhda ah ee aan milmi karin biyaha ≤0.05%
Kaalshiyamka iyo magnesium ion waxa ku jira ppm ≤4000

Waxaan si adag u aaminsanahay in sumcadda wanaagsan ay ka timaaddo alaabada ay aqoonsan yihiin isticmaalayaashu, agab wax soo saar la isku halayn karo oo deggan, iyo adeeg fiiro gaar ah leh. Waxaan diyaar u nahay inaan si wadajir ah u horumarino macaamiisheena iyo la-hawlgalayaashayada!
