Dareeraha ugu weyn wuxuu ku milmi karaa filimka rinjiga iyadoo loo marayo molikaliska dhexdiisa iyo barar, taasoo baabiin karta ku dhejinta filimka rinjiga qeybta hoose iyo qaab dhismeedka goobta filimka rinjiga, sidaa darteed benzene, hydrocarbon, ketone iyo ether ayaa guud ahaan loo isticmaalaa inay yihiin dareeraha ugu muhiimsan , iyo hydrocarbon ayaa ugu fiican. Waxyaabaha ugu mihiimsan waa benzene, hydrocarbons, ketones iyo ether, iyo hydrocarbons ayaa ugu fiican. Rinjiraha rinjiga liita ee sunta yar ee aan ku jirin methylene chloride badanaa wuxuu ka kooban yahay ketone (pyrrolidone), ester (methyl benzoate) iyo ether aalkolo (ethylene glycol monobutyl ether), iwm. Ethylene glycol ether wuxuu ku fiican yahay polymer resin. Ethylene glycol ether waxay leedahay milix adag oo polymer, permeability wanaagsan, dhibic karkaraya, qiimo jaban, sidoo kale waa mid wanaagsan oo wanaagsan, sidaas darteed waxay ku firfircoon tahay cilmi baarista u adeegsiga iyada oo ah dareeraha ugu muhiimsan ee lagu diyaariyo rinjiga rinjiga (ama wakiilka nadiifinta) oo leh saameyn wanaagsan iyo shaqooyin badan.

Molikuyuullada 'benzaldehyde' waa yar tahay, oo dhexgalkeeda silsiladda makromolecules waa mid xoog badan, isla markaana ay ku milmi karto walxaha dabiiciga ee polar sidoo kale waa mid aad u xoog badan, taasoo ka dhigi doonta macromolecules-ka inay kordhiyaan mugga oo ay soo saaraan walwal. Sumoobaanta hooseysa iyo midabka rinjiga jilicsan ee hooseeya ee lagu diyaariyo benzaldehyde maadaama dareeraha uu si wax ku ool ah uga saari karo dusha sare ee dufanka epoxy dusha sare ee maadada birta heerkulka qolka, sidoo kale wuxuu ku habboon yahay saarista rinjiga maqaarka diyaaradaha. Waxqabadka rinjiyeyaasha rinjiga ayaa la barbardhigi karaa kuwa wax lagu rido rinjiyeyaasha kiimikada dhaqameed (nooca methylene chloride iyo nooca alkali kulul), laakiin aad ayuu uga hooseeyaa nabarrada birta.

Limonene waa qalab wanaagsan oo loogu talagalay rinjiyeyaasha rinjiga laga soo qaado dhinaca dib loo cusboonaysiin karo. Waa dareeraha hydrocarbon-ka laga soo saaro diirka liinta, diirka tangerine iyo diirka liinta. Waa dareeraha ugu fiican ee dufan, wax iyo cusbo. Waxay leedahay bar kuleyl badan iyo barta dabka waana aamin in la isticmaalo. Ester dareeraha ayaa sidoo kale loo isticmaali karaa sidii alaabta ceeriin ee rinjiyeynta rinjiga. Waxyaabaha loo yaqaan 'Ester solvents' waxaa lagu gartaa sumoobo hoose, ur udgoon iyo biyo aan lagu milmi karin, waxaana inta badan loo isticmaalaa sidii dareerayaasha walxaha dabiiciga ah ee saliidda leh.

Waxay sidoo kale yareyn kartaa qiyaasta dareeraha ugu muhiimsan waxayna yareyn kartaa qiimaha. Alcohols, ether iyo esters ayaa badanaa loo isticmaalaa inay yihiin wax-wadayaal.

3) Dhiirrigeliye

Dhiirrigeliyuhu waa tiro ka mid ah dareerayaasha nucleophilic, badanaa asiidhyada dabiiciga ah, phenols iyo amines, oo ay ku jiraan formic acid, acetic acid iyo phenol. Waxay ku shaqeysaa burburinta silsiladaha macromolecular, dardargelinta gelitaanka iyo bararka daahan. Aashitada Organic-ka waxay ka kooban tahay isla koox shaqeysa sida ka kooban filimka rinjiga - OH, waxay la falgeli kartaa nidaamka iskutallaabta ee oksijiin, nitrogen iyo atamka kale ee polarka, iyadoo kor loo qaadayo nidaamka qeyb ka mid ah qodobbada isku xirnaanta jirka, sidaasna ay ku sii kordheyso rinjiyeha rinjiga heerka baahinta daahan dabiici ah, hagaajiyo bararka filimka rinjiga iyo awoodda duudduuban. Isla mar ahaantaana, asiidhyada dabiiciga ah ayaa kicin kara hydrolysis-ka isku-xidhka ester, isku-xidhka isku-xidhka ee polymer-ka oo ka dhigaya inuu jebiyo isku-xidhka, taasoo keenta luminta adkaanta iyo ka-goysyada jilicsan ka dib rinjiyeynta rinjiga.

Biyaha la gooyay waa dareeraha joogtada ah ee dielectric (ε = 80120 at 20 ℃). Marka dusha sare ee laga jarayo uu yahay cirif, sida polyurethane, dareeraha joogtada ah ee dilaa dielectric wuxuu saameyn togan ku yeelanayaa kala sooca dusha korantada, si ay dareeraha kale u dhex galaan daloolada u dhexeeya daaha iyo substrate-ka.

Hydrogen peroxide way ku jajabtaa inta badan meelaha biraha, soo saarista oksijiin, hydrogen iyo qaab atom ah oo oksijiin ah. Ogsijiintu waxay keentaa in lakabka difaaca ee jilicsan uu soo duuduubo, taasoo u oggolaanaysa xargaha rinjiga cusub inuu dhex galo birta iyo dahaadhka, sidaas awgeedna uu xawaareynayo hawsha kala-bixidda. Acids sidoo kale waa qayb weyn oo ka mid ah sameynta rinjiyeyaasha rinjiyeynta, shaqadooduna waa inay ilaaliso pH-ka midabka rinjiyeynta 210-510 si ay ula falgalaan kooxaha amine ee bilaashka ah ee dharka sida polyurethane. Asiidhka la isticmaalay wuxuu noqon karaa acid adag oo milmi kara, asiidh dareere ah, asiidh dabiici ah ama aashitoor aan dabiici ahayn. Maaddaama acid-ka aan dabiici ahayn ay u badan tahay inuu soo saaro daxalka birta, sidaas darteed waxaa ugu wanaagsan in la isticmaalo qaacido guud oo RCOOH ah, culeyska molikiyuulka ee ka yar 1,000 aashitada organic-ka ah, sida formic acid, acetic acid, propionic acid, butyric acid, valeric acid, hydroxyacetic aashitada, hydroxybutyric acid, lactic acid, citric acid iyo hydroxy acids kale iyo isku darka.

4) Caarada

Haddii rinjiyeyaasha loo isticmaalo qaybo waaweyn oo qaab dhismeed ah oo u baahan in loo hoggaansamo dusha sare si looga jawaabo, waxaa lagama maarmaan ah in lagu daro dhumucleyda sida polymerka biyaha ku milma sida cellulose, polyetylen glycol, iwm, ama cusbada aan dabiici ahayn sida sodium chloride , potassium chloride, sodium sulfate, iyo magnesium chloride. Waa in la ogaadaa in dhalooyinka cusbada aan dabiici ahayn ay isku dheelitiraan isku-dheellitirnaanta ku kordhayaan qiyaastooda, wixii intaa ka dambeeya, isugeyntii waa la dhimayaa halkii, xulashada aan habboonayn sidoo kale waxay saameyn ku yeelan kartaa qaybaha kale.

Khamriga Polyvinyl waa polymer-biyo-milma, oo leh biyo-dhalaal wanaagsan, filim sameynta, adhesion iyo emulsification, laakiin kaliya waxoogaa iskudhisyo dabiici ah ayaa kala diri kara, iskudhafka polyol sida glycerol, ethylene glycol iyo culeyska molikal polyetylen glycol, amide, triethanolamine cusbo, dimethyl sulfoxide, iwm, waxyaabaha dareeraha ah ee kor ku xusan, ku milma qadar yar oo aalkolada polyvinyl ah sidoo kale waxay u baahan yihiin in la kululeeyo. Polyvinyl aquous solution with benzyl alcohol and formic acid ድብልቅ isku dheelitirka liita, lakab fudud, isla mar ahaantaana leh methyl cellulose, hydroxyethyl cellulose solubility oo liita, laakiin iyo karboxyxy methyl cellulose solubility ayaa kafiican.

Polyacrylamide waa polymer-biyo-milma toosan, iyada iyo waxyaabaha ka dhasha ayaa loo isticmaali karaa sida flocculants, thickeners, enhancer paper, retarders, iwm. xalka dabiiciga ah, sida methanol, ethanol, acetone, ether, aliphatic hydrocarbons iyo hydrocarbons aromatic. Xalka aqueous Methyl cellulose ee nooca aalkolada benzyl ee aashitada xasiloon, iyo noocyo kala duwan oo walxaha biyaha ku milma ayaa leh isku dhafnaan wanaagsan. Qadarka nafwaayaha waxay kuxirantahay shuruudaha dhismaha, laakiin saameynta sii kordheysa si toos ah uguma ekeysna xaddiga, iyadoo ay kordheyso xaddiga isugeynta, xalka aqueous-ka ayaa si tartiib tartiib ah u yareynaya heerkulka hawada. Nooca Benzaldehyde laguma kordhin karo adoo ku daraya maadada methyl cellulose si loo gaadho saamayn nafwaayay oo muhiim ah.

5) Ka hortaga daxalka

Si looga hortago wasakhda substrate (gaar ahaan magnesium iyo aluminium), qadar cayiman oo ka hortagga daxalka waa in lagu daraa. Wax isdabamarintu waa dhibaato aan la iska indha tiri karin habka wax soo saarka dhabta ah, walxaha lagu daweeyay rinjiyeyaasha rinjiga waa in lagu dhaqaa oo lagu qallajiyaa biyo ama lagu dhaqaa rosin iyo baasiin waqtiga ku habboon si loo hubiyo in biraha iyo walxaha kale aysan xumaan.

6) Xakameeyayaasha kacsan

Guud ahaan marka la hadlayo, maaddooyinka leh awood-socodsiinta wanaagsan way fududahay in la-buuxiyo, sidaa darteed si looga hortago is-beddelka meerkullalka muhiimka ah, qaddar cayiman oo ka-hortagga is-beddelka ah waa in lagu daraa rinjiyeha rinjiga si loo yareeyo ficil-celinta dareerayaasha dareeraha ee habka wax soo saarka , gaadiidka, keydinta iyo isticmaalka. Marka rinjiga rinjiga leh wax yaabaha loo yaqaan 'paraffin wax' laga mariyo dusha rinjiga, lakab khafiif ah oo wax sumaysan ayaa laga soo saari doonaa dusha sare, si moleculeyaasha ugu waaweyn ee dareeraha ay u heli doonaan waqti ku filan oo ay ku sii nagaadaan kuna dhex galaan filimka rinjiga si looga saaro, sidaas darteed hagaajinta saamaynta midabaynta rinjiga. Waxyaabaha adag ee loo yaqaan 'paraffin para' oo keliya ayaa inta badan sababi doona kala-fiiqid liidata, qaddar yar oo ka mid ah wax-daaqaha saliida leh ayaa ku sii jiri doona dusha sare ka dib marka laga saaro rinjiga, taas oo saameyn ku yeelan doonta dib-u-buufinta. Haddii ay lagama maarmaan noqoto, ku dar emulsifier si loo yareeyo xiisadda dusha sare si wax daloolada iyo dareeraha dareeraha paraffin ay si fiican u kala firdhi karaan oo xasilloonidiisa keydinta loo horumarin karo.

7) Hawl-yaqaan

Ku darista waxyaabaha dusha sare ka shaqeeya, sida 'amphoteric surfactants' (tusaale, imidazoline) ama ethoxynonylphenol, waxay gacan ka geysan kartaa hagaajinta xasilloonida keydinta qashin-qadaha rinjiga iyo fududeynta in lagu mayro rinjiga biyaha. Isla mar ahaantaana, isticmaalka maaddooyinka loo yaqaan 'surfactant molecules' oo leh labada lipophilic iyo hydrophilic labadaba ee ka soo horjeedka aaladda, waxay saameyn ku yeelan kartaa saameynta milanka; isticmaalka saameynta kooxda kolloidol ee dusha sare, sidaa darteed milanka dhowr qaybood oo ku jira dareeraha ayaa si weyn kor ugu kacay. Waxyaabaha sida caadiga ah loo isticmaalo waa propylene glycol, sodium polymethacrylate ama sodium xylenesulfonate.
