RFE-gayaga, waa adkeysi xabag oo thiophosphoric-tris-(p-isocyanato-phenyl ester) oo ku jira ethyl acetate, lambarka CAS 4151-51-3. Midabka khafiifka ah waa wakiil daaweyn caalami ah / iskutallaab (nooca isocyanate) oo si weyn loogu dabaqo dhejisyada loogu talagalay caagga dabiiciga ah iyo/ama macmal ah, gaar ahaan agabka caagga. Iyada oo ay ugu wacan tahay midabkeeda khafiifka ah ee iska caabbinta aan midabka lahayn iyo jaallaha ahayn, RFE waa xal ku habboon baahida adag ee midabka, oo si fiican ugu habboon dhejiska cr ee la tallaalay, dhejiska caagga chloroprene iyo dhejiska polyurethane ee hydroxyl. RFE sidoo kale waxay hagaajin kartaa isku xirnaanta PVC-ga balaastikada ah, SBR saliid leh, maqaarka sare/asalka ah, xariir iyo iwm. RFE sidoo kale waxaa lagu dari karaa wakiilka daaweynta maqaarka saliidda si loo helo xoojin dhejis oo wanaagsan iyo iska caabbinta saliidda. Dareeraha RFE waa ethyl acetate (EAC), kaas oo la jaan qaadaya nidaaminta ilaalinta deegaanka marka la barbar dhigo methylene chloride. Ku darista RFE dhejisyada, waxay keentaa falcelinta isku xidhka iyo walxaha isku xidhka, gaar ahaan agabka caagga.
Koolada laba-qaybood leh waa in la isticmaalaa muddada ku habboon ka dib marka la geliyo ka dib marka la geliyo RFE. Muddada ku habboon ma aha oo kaliya waxa ku jira polymer-ka ee koolada, laakiin sidoo kale qaybaha kale ee khuseeya (Sida reisn, antioxygen, plasticizer, dareeraha, iwm. Marka ay ku dhowdahay muddada ku habboon, badanaa dhowr saacadood ama hal maalin oo shaqo ah, koolada way adkaanaysaa in la shaqeeyo, dhesqushana way kor u kacdaa dhawaan, Ugu dambeyntii, waxay noqotaa jelly aan la celin karin.
RFE waxaa loo isticmaali karaa sida dhejiska caagga iyo birta, iyo sidoo kale sidii wakiil daaweyn iskutallaab ah oo loogu talagalay dhejisyada xalka caagga ah iyo dhejisyada polyurethane ee ku salaysan dareeraha.
Qaddarka guud ahaan waa 4% ilaa 7% xabagta ku salaysan dareeraha ee kor ku xusan. Waxaa si gaar ah loogu isticmaalaa isku xirka alaabada aan midabka lahayn ama kuwa midabka khafiifka ah leh.
Codsiga oo ay ku jiraan:
- Isku xidhka caagga vulcanized (ama aan vulcanized) iyo PVC, PU, SBS iyo polymers kale oo isku xidha agabka iyo biraha (birta/aluminium).
- Sida wakiilka daaweynta ee dhejisyada neoprene si loo hagaajiyo xoogga isku xidhka; wakiilka daaweynta ee isku xidhka caagga iyo dharka.
- Sida wakiil isku xidha qaybaha hydroxyl ee alaabta polyurethane (elastomers, dahaarka, iwm.).
- Sida wakiil isku xidha oo loogu talagalay dhejisyada polyurethane ee hydroxyl-ka ah ee loo isticmaalo warshadaha kabaha, kuwaas oo hagaajin kara xoogga dhegdhegga bilowga ah, iska caabbinta kulaylka iyo tilmaamayaasha kale.
- Badanaa waxaa lagu dabaqaa kabaha, boorsooyinka, bacaha si loogu xidho dharka PVC iyo/ama PU.
Qiyaasta lagu taliyay:
Iyada oo ku xidhan habka isku xidhka iyo substrate-ka, qiyaasta ugu habboon ayaa lagu talinayaa noocyo badan oo kala duwan oo ikhtiyaarro ah.
Ku daawayn koollo 100 qaybood ah miisaan ahaan (pbw) iyadoo lagu saleynayo:
Caag Graft-Chloroprene ah (qiyaastii 16%): 3%-5% pbw RFE
Cinjirka Chloroprene (qiyaastii 20%): 5%-7% Pbw RFE
Hydroxyl polyurethane (qiyaastii 15%): 3%-5% pbw RFE
U hoggaansanaanta dareerayaasha:
RFE-keena waxaa lagu qasi karaa ethyl acetate dichloropropane, trichloroethylene, acetone, methyl ethyl ketone, toluene iyo dareere kale. Ku darista qaybo badan oo hydrocarbons aliphatic ah waxay keeni kartaa wasakh. Si kastaba ha ahaatee, xalka hydrocarbons aliphatic ee caagga dabiiciga ah (NR) wuxuu muujinayaa iswaafajin wanaagsan oo RFE ah. Sidaa darteed, looma baahna in lagu daro dareere kale.

Kaydinta:
Fadlan ku kaydi weelka asalka ah ee la shaabadeeyey 5℃-32℃, badeecadaha waxaa lagu hayn karaa mid deggan 12 bilood.
Dhammaan alaabadayada taxanaha ah aad bay ugu nugul yihiin qoyaanka; Waxay soo saari doontaa kaarboon laba ogsaydh iyo urea aan milmi karin falcelinta biyaha. Haddii ay la kulanto hawada ama/iyo iftiinka, waxay dedejin doontaa isbeddellada midabka ee alaabada.
(Laakiin shaqada wax ku oolka ah ayaa saameyn doonta bot-ka.)
Badbaadada:
Dabeecad khatar ah, oo aad u guban karta, ayaa indhaha ku kicisa, haddii la neefsado waxay sababi kartaa xasaasiyad. Taabashada joogtada ah waxay keeni kartaa in maqaarku engego ama uu waasho. Uumiga alaabtu wuxuu qofka ka dhigi karaa daal iyo wareer.
