Dhammaystirka duntu waa hab habaysan oo loogu talagalay in lagu wanaajiyo muuqaalka iyo tayada gudaha ee duntu, kor u qaadida xidhidashadooda iyo hawl qabadkooda, ama lagu siiyo hawlo gaar ah iyada oo loo marayo hab jidheed ama kiimiko. Habkan waxaa sida caadiga ah lagu habeeyaa marxaladda dambe ee midabaynta iyo dhamaystirka, sidaas darteed waxaa si ballaaran loogu tilmaamaa dhameynta ka dib.
Dhamaystirka dharka, noocyada kala duwan ee walxaha silikon organic waxaa loo isticmaali karaa in lagu siiyo dunta leh sifooyin kala duwan iyada oo loo marayo isdhexgalka jireed ama kiimikaad ee fiilooyinka, si loo gaaro ujeedada dhamaystirka. Waxaa ka mid ah, saliidda silikoon ee ku salaysan walxaha silikoon organic waxay door muhiim ah ka ciyaaraan dhamaystirka jilicsan, dhamaystirka biyaha, dhamaystirka ka-hortagga wasakhda, iyo dhamaystirka ka-hortagga laalaabka ee dunta, waana wakiilada dhamaystirka asaasiga ah si loo gaaro qiimo sare oo lagu daray iyo shaqeynta sare ee dharka.
①Wakiilka dhamaystirka jilicsan ee silicone ee dunta
1. Muhiimada dhamaystirka jilicsan: Cudbiga iyo fiilooyinka kale ee dabiiciga ah waxay leeyihiin jilicsanaan gaar ah sababtoo ah joogitaanka dufanka iyo walxaha dhuka, halka fiilooyinka synthetic lagu dahaadho walxaha saliidda ah. Si kastaba ha ahaatee, ka dib marka la maro sifaynta, bleaching, iyo daabacaadda iyo hababka rinjiyeynta, dhuka iyo saliidda fiilooyinka ayaa la saaraa, taas oo keentay qaab qallafsan oo adag oo dharka ah. Sidaa darteed, fulinta dhamaystirka jilicsan ayaa si gaar ah muhiim u ah.
2. Faa'iidada jilciye silikoon organic waa in la marsado jilciye on maryaha waa hab wax ku ool ah si loo yareeyo isku xidhka isku dhafka ah ee u dhexeeya fiilooyinka iyo dunnooyinka, iyo helitaanka dareen gacan jilicsan oo siman. Waxaa ka mid ah, jilciyaasha silikon organic waxay noqdeen doorashada la doorbido ee dhamaystirka jilicsanaanta dunta sababtoo ah codsigooda ballaaran, waxqabadka wanaagsan, iyo saameynta muuqda.
Jilciyeyaasha silikoon-dabiiciga ah ee inta badan ka kooban saliid silikoon wax laga beddelay waxay la kulmi karaan falcelin isku-dhafan oo fiilooyinka si ay u sameeyaan habayn jihayn, taas oo si weyn u wanaajinaysa dabacsanaanta dharka. Iyada oo la sii wanaajinayo oo la isku darayo saliidda silikoon ee amino modified, taxane noocyo jilicsan oo silikoon ah oo leh astaamo qaab oo kala duwan ayaa sidoo kale la soo saari karaa.
3. Qiimaynta dhamaystiran ee jilicsanaanta dharka (sidoo kale loo yaqaan dareenka gacanta, qaabka) waa falcelin adag oo dhamaystiran oo ku lug leh qaar ka mid ah sifooyinka jirka iyo farsamada ee dharka, waxaana ka muuqda dareenka gacmaha bini'aadamka iyo aragtida. Dareen-celintan waxaa ka mid ah jilicsanaan, jilicsanaan, qaboojin, qallafsanaan, dabacsanaan, adkaanta unugyada, dhalaalid, diirimaad iyo qabow, iyo sidoo kale muuqaal muuqaal ah. Sababtoo ah la'aanta heerarka tirada ee lagu qiimeeyo jilicsanaanta, waxay inta badan ku tiirsan tahay dareenka shakhsi ahaaneed.
4.In dheer in la siiyo dhar jilicsan oo wanaagsan, jilicsanaan, iyo sifooyin taabasho ah, shuruudaha codsiga ee jilicsanaanta silikoon waa inay sidoo kale buuxiyaan shuruudaha soo socda: xasilloonida: xalinta dhamaystirka la sameeyay waa inuu ahaado mid xasilloon oo hoos yimaada xaalado kala duwan oo jilicsan. Oo ay ku jirto xasilloonida xiirid (sida saliid aan sabbeyn ama ku dhejinta rollers ee tijaabooyinka xiirta xawaaraha xariiqda 12.5m/min) iyo xasilloonida kulaylka (sida saliid sabbaynaysa ama delamination in ka badan 30 daqiiqo at 100-105 ℃).
Cadaadiska iyo midabka midabka: Ha yareynin cadaanka dharka, waana in aysan jirin jaale ah dharka biliijka ah; Dharka midabka leh ama daabacan, farqiga midabka yar ee dharka asalka ah, ayaa ka sii fiican. Guud ahaan, heerka farqiga midabka ayaa loo baahan yahay inuu ka sarreeyo 4.5. Waa in la ogaadaa in farqiga midabku aanu kaliya la xiriirin jilicsanaanta, laakiin sidoo kale waxay si dhow ula xiriirtaa xawaaraha midabka iyo habka dharka midabka asalka ah.
Iska caabinta kulaylka iyo xasilloonida kaydinta: Dharka ka dib dhammaystirka jilicsan ma beddelo midab marka la kululeeyo, mana jiraan wax isbeddel ah oo ku yimaada midabka, dareenka, ama ur inta lagu jiro kaydinta.
Badbaadada Maqaarka: Dharka jilicsan ee la dhammeeyey waa inaysan yeelan wax saameyn ah marka maqaarka la taabto.
②Amino wax laga beddelay polydimethylsiloxane wakiilka dhamaystirka jilicsan
Amino modified polydimethylsiloxane (oo loo soo gaabiyo saliid silikoon amino) ayaa door muhiim ah ka ciyaara wakiilada dhamaystirka jilicsan ee dharka. Waxaa ka mid ah, in ka badan 90% saliidda silikoon ee amino silikoon wakiilada dhamaystiraya waxay isticmaalaan copolymers N - β - aminoethyl - γ - aminopropylmethylsiloxane iyo dimethylsiloxane sida maaddooyinka firfircoon. Qaab dhismeedka molecular ee gaarka ah wuxuu u sahlayaa saliidda silikoon ee amino inay la falgalaan kooxaha shaqeynaya sida hydroxyl iyo kooxaha karboxyl ee dusha sare ee fiber-ka, taasoo ku hagaya laf dhabarta siloxane inay u hoggaansamaan dusha sare ee fiber-ka, taasoo si weyn u yareyneysa isku-xirnaanta isku-dhafka ah ee u dhexeeya fiilooyinka waxayna siinaysaa dharka jilicsan jilicsan iyo jilicsanaan aad u fiican.
1. Qaab dhismeedka molecular iyo saamaynta jilicsan ee saliidda silikoon amino waxay saameyn weyn ku leedahay saameynteeda jilicsan. Guud ahaan, marka qiimaha ammonia uu hooseeyo, si loo helo dabacsanaan wanaagsan, waxaa lagama maarmaan ah in si habboon loo kordhiyo viscosity ee saliidda silicone ee amino. Dhanka kale, kala duwanaanta iyo darajada dharka ayaa sidoo kale ah arrimo muhiim ah in la tixgeliyo marka la dooranayo cabbirada saliidda silikoon ee amino. Intaa waxaa dheer, habka diyaarinta ee looshanku wuxuu sidoo kale saameyn doonaa saameynta jilicsanaanta iyo xasilloonida habka dhamaystirka. Sidaa darteed, ka dib marka la doorto noocyada ku habboon ee saliidda silikoon ee amino, waxaa lagama maarmaan ah in la horumariyo habka qaabeynta macquulka ah ee wakiilka dhamaystirka si loo hubiyo soo saarista saliidda silikoon amino-ka jilicsan ee jilicsan ee ku habboon dhar kala duwan.
2.Amino saliid silikoon jilcisa wakiilka ka kooban N - β - aminoethyl - γ - aminopropyl group Si loo hagaajiyo kala firidhsan emulsification ee saliid silikoon amino, acid amino in ay molecule la dhexdhexaadin karaa si ay u diyaariyaan lotion micro hufan la size qayb ka yar 50nm. Kareemka yar-yar wuxuu leeyahay xasillooni sare si uu u qabo cadaadiska farsamada iyo kulaylka, wuxuuna ka fogaan karaa demulsification iyo biliijka saliidda inta lagu jiro dhamaystirka dharka.
3. Doorashada surfactant waa mid aad muhiim u ah diyaarinta saliid silikoon amino lotion micro.
Non ionic, cationic, ama zwitterionic surfactants waa la isticmaali karaa, laakiin la tixgelinayo xasiloonida la socon kara waxyaabaha kale ee ionic, non-ionic ama zwitterionic surfactants ayaa guud ahaan la door bidaa. Surfactants non-ionic sida polyoxyethylene alkyl aldehydes, polyoxyethylene isomeric alkyl ethers, iwm waxaa loo isticmaali karaa iyadoo la isku daray laba ama in ka badan surfactants leh qiimaha HLB kala duwan, iyo qiimaha HLB ka dib marka la isku daro waa in la xakameeyo inta u dhaxaysa 1215. Qiyaasta habboon ee surfactant waa 3070 qaybood. Haddii ay aad u hooseyso, ma sameyn doonto microemulsion leh cabbirka qayb ka yar 100nm. Haddii ay aad u sarreyso, waxay ku sii jiri doontaa fiilooyinka waxayna caqabad ku noqon doontaa waxqabadka saliidda silikoon ee amino.
Asiidhyada karboksilic ee dabiiciga ah sida formic acid iyo acetic acid ayaa loo isticmaali karaa in laga takhaluso asiidhyada amino, iyo sidoo kale amino ka kooban acids sida glutamic acid. Inta lagu guda jiro nidaamka emulsification, qase-xawaaraha sare isku mid ah iyo qalabka kale ee emulsifying waxaa loo isticmaali karaa in lagu daro aashitada ka dib emulsification ama wada jir biyo. Haddii kale, saliid silikoon amino si siman loogu qasi karaa surfactants ka hor inta aan lagu darin biyo iyo acid. Xasiloonida kareemka waxaa lagu sii wanaajin karaa iyadoo lagu daweynayo 6080 ℃ 320 saacadood.
4. Tusaalaha Habka Diyaarinta Dhamaystirka Wakiilka
(1) Amino silikoon saliid jilcisa oo lagu diyaariyey surfactants non-ionic waxaa lagu daraa 2L beaker leh xad gaar ah oo saliid silikon, polyoxyethylene lauric ether, iyo biyo. Ka dib markaad ku walaaqdo isku-darka isku midka ah, formic acid ayaa lagu daraa dhexdhexaadinta. Ka dib isku darka ku wareeji weel, oo ku daawee qasiyaha slurry at 80 ℃ wakhti go'an si aad u hesho microemulsion cad oo buluug ah. Jilciyaha kareemka yar yar wuxuu leeyahay xasillooni kaydineed oo aad u wanaagsan, ma laha wax demulsification ka dib hal sano oo heerkulka qolka ah, iyo xasilloonida milanka wanaagsan iyo xasilloonida farsamada. Intaa waxaa dheer, ku darida xeryahooda aalkolada ee binary-ka ah sida ethylene glycol monomethyl ether waxay sii wanaajin kartaa xasilloonida kuleylka, xasilloonida milanka iyo hufnaanta kareemka yar yar.
(2) Amino saliid silikoon jilicsan oo lagu diyaariyey zwitterionic surfactant Saliida silikoon ee saliidda kiriimyada yar yar ee looshanka leh ee loo diyaariyey zwitterionic surfactant waxay leedahay sifooyin habka diyaarinta fudud, dib-u-celinta wanaagsan, iyo qadar hoose ee surfactant. Microemulsion-ka la diyaariyey waa mid aad u xasilloon oo lagu xiiro xoogga, mana nijaasayn doono dharka sababtoo ah demulsification ee habka dhamaystirka dharka, oo leh jilicsanaan iyo jilicsanaan wanaagsan. Markaad diyaarinayso, marka hore isku qas saliid silikoon amino, surfactant zwitterionic, aalkolo, iyo qadar yar oo biyo ah si aad u sameysid xoog, ka dibna walaaq oo ku qas biyo.
