Biyaha deionized waa dareere joogto ah dielectric sare (ε=80120 at 20 ℃). Marka dusha sare ee la kaxayo ay tahay polar, sida polyurethane, dareeraha joogtada ah ee dielectric sare wuxuu saameyn togan ku leeyahay kala soocida dusha sare ee elektrostatic, si dareeraha kale ay u dhexgalaan daloolada u dhexeeya daaha iyo substrate-ka.

Hydrogen peroxide waxay ku duntaa sagxadaha birta badankooda, iyagoo soo saara ogsijiin, hydrogen iyo nooc atomic ah oo ogsijiin ah. Ogsajiinta waxay keentaa lakabka difaaca ee jilicsan inuu soo rogo, taas oo u oggolaanaysa rinjiga cusub inuu dhex galo birta iyo dahaarka dhexdooda, sidaas awgeed waxay dedejisaa habka qaadista. Acids sidoo kale waa qayb muhiim ah oo ka mid ah hababka rinjiga jeexjeexa, shaqadooduna waa inay ilaaliyaan pH ee rinjiga 210-510 si ay uga falceliyaan kooxaha amine ee bilaashka ah ee dahaarka sida polyurethane. Ashitada la isticmaalo waxa ay noqon kartaa asiidh adag oo milma, aashitada dareere ah, aashitada organic ama aashitada inorganic. Maaddaama aashitada inorganic ay u badan tahay inay soo saarto daxalka birta, sidaas awgeed waxaa ugu wanaagsan in la isticmaalo caanaha guud ee RCOOH, miisaanka kellika ah ee ka yar 1,000 acids organic soluble, sida formic acid, acetic acid, propionic acid, butyric acid, valeric acid, hydroxyacetic acid, hydroxybutyric acid, lactic acid, citric acid iyo hydroxy acids kale iyo isku darkooda.

4) Dhumucyada

Haddii rinjiga loo isticmaalo qaybo dhismeed oo waaweyn oo u baahan in lagu dhejiyo dusha sare si ay uga falceliyaan, waxaa lagama maarmaan ah in lagu daro dhumucyada sida polymers-ka biyaha ku milma sida cellulose, polyetylen glycol, iwm, ama cusbada aan dabiiciga ahayn sida sodium chloride. , chloride potassium, sodium sulfate, iyo magnesium chloride. Waa in la ogaadaa in dhumucda milixdu ay hagaajinayso viscosity waxay kordhin doontaa qiyaastooda, ka baxsan xadkan, mawqifka ayaa la dhimay halkii, xulashada aan habooneyn waxay sidoo kale saameyn ku yeelan kartaa qaybaha kale.

Aalkolada Polyvinyl waa polymer-ka biyaha ku milma, oo leh milmi biyo wanaagsan, filim-samayn, dhejis iyo emulsification, laakiin kaliya dhowr xeryood oo organic ah ayaa milmi kara, xeryahooda polyol sida glycerol, ethylene glycol iyo miisaanka molecular hoose ee polyetylen glycol, amide, triethanolamine cusbo, dimethyl sulfoxide, iwm, ee dareerayaasha organic ee kor ku xusan, milaan qadar yar oo ah khamriga polyvinyl waa in sidoo kale la kululeeyaa. xal aqueous alkolada polyvinyl alkolada benzyl iyo formic acid isku dar ah oo waafaqid liidata, lakabka fudud, iyo waqti isku mid ah la cellulose methyl ah, hydroxyethyl cellulose solubility ee saboolka ah, laakiin iyo karboxy methyl cellulose solubility waa ka fiican.

Polyacrylamide waa polymer toosan oo biyo-milmi leh, iyada iyo waxyaabaha ka soo baxa waxaa loo isticmaali karaa sida flocculants, dhumucyada, kor u qaadayaasha waraaqaha iyo dib-u-celinta, iwm. xalalka organic, sida methanol, ethanol, acetone, ether, aliphatic hydrocarbons iyo hydrocarbons udgoon. Methyl cellulose xal aqueous ah oo ku jira nooca alkolada benzyl ee acid aad u deggan, iyo noocyo kala duwan oo walxaha biyo-milmi leh ayaa leh iskudhaf wanaagsan. Qadarka viscosity waxay kuxirantahay shuruudaha dhismaha, laakiin saameynta dhumucdeedu maaha mid si toos ah u dhiganta qadarka, iyada oo la kordhinayo qadarka lagu daray, xalka aqueous wuxuu si tartiib tartiib ah u yareeyaa heerkulka gelation. Nooca Benzaldehyde laguma kordhin karo methyl cellulose si loo gaaro saameyn weyn oo viscosity ah.

5) Xakamaynta Daxalka

Si looga hortago daxalka substrate-ka (gaar ahaan magnesium iyo aluminium), waa in lagu daraa xaddi go'an oo ah daxalka. Daxalka waa dhibaato aan la iska indho tiri karin habka wax-soo-saarka dhabta ah, waana in walxaha lagu daaweeyaa rinjiga lagu dhaqo oo lagu qallajiyaa biyo ama lagu dhaqo bassin iyo basiin waqtigeeda si loo hubiyo in birta iyo walxaha kale aysan daxaloobayn.

6) Ka-hortaggayaasha kacsan

Guud ahaan, walxaha leh qulqulka wanaagsan waa sahlan tahay in la beddelo, markaa si looga hortago isbeddelka molecules dareeraha ugu muhiimsan, qadar go'an oo ka mid ah xakamaynta isbeddelka waa in lagu daraa rinjiga rinjiga si loo yareeyo isbeddelka molecules dareeraha ee habka wax soo saarka. , gaadiidka, kaydinta iyo isticmaalka. Marka rinjiga roogga leh ee wax-ka-qabashada ah lagu dhejiyo dusha rinjiga, lakab khafiif ah oo dhuxul ah ayaa ka sameysan doona dusha sare, si molecules-ka ugu muhiimsan ee dareeraha ah ay u helaan waqti ku filan oo ay ku joogaan oo ay galaan filimka rinjiga si looga saaro, sidaas darteed hagaajinta saamaynta rinjiyeynta. Shabakada adag ee paraffin keligiis waxay badanaa keeni doontaa kala firdhisanaan liidata, iyo qadar yar oo shabag ah ayaa ku hadhi doona dusha sare ka dib marka rinjiga laga saaro, taas oo saameyn doonta dib-u-buufinta. Haddii loo baahdo, ku dar emulsifier si aad u yarayso xiisadda dusha sare si dhuka paraffin iyo shabagga dareeraha ah ay si fiican u kala firdhiyaan oo xasiloonida kaydinta loo wanaajiyo.

7) Surfactant

Ku darida qalabka wax-soo-saarka, sida amphoteric surfactants (tusaale, imidazoline) ama ethoxynonylphenol, waxay gacan ka geysan kartaa hagaajinta xasilloonida kaydinta rinjiga iyo fududaynta rinjiga biyo lagaga luqluqdo. Isla mar ahaantaana, isticmaalka molecules surfactant oo leh labadaba lipophilic iyo hydrophilic laba dabeecadood oo ka soo horjeeda surfactant, waxay saameyn kartaa saameynta solubilization; Isticmaalka saamaynta kolloidal kooxda surfactant, si ay u milmay dhowr qaybood oo dareere ah ayaa si weyn u kordhay. Surfactants-yada sida caadiga ah loo isticmaalo waa propylene glycol, sodium polymethacrylate ama sodium xylenesulfonate.
