Chlorobenzene / CAS Nambarka: 0.5%
RFE-keena, waa koolada dareeraha leh ee thiophosphoric-tris-(p-isocyanato-phenyl ester) ee ethyl acetate, lambarka CAS 4151-51-3. Midabka-iftiinku waa wakiilka daawaynta caalamiga ah / crosslinker (nooca isocyanate) oo si weyn loogu dabaqay xabagyada loogu talagalay caag dabiici ah iyo/ama synthetic, gaar ahaan qalabka caagga ah. Faa'iidooyinka leh midabka iftiinka ilaa caabbinta midab la'aanta iyo huruudda ah, RFE waa xal ku habboon baahida adag ee midabka, oo si fiican ugu habboon koollada crista, koollada chloroprene iyo xabagta polyurethane hydroxyl. RFE waxa kale oo ay wanaajin kartaa isku xidhka balaastigga PVC, SBR saliid leh, lakabka sare/maqaar hore, xariir iyo iwm. Walxaha RFE waa ethyl acetate (EAC), kaas oo la jaan qaadaya nidaamka ilaalinta deegaanka marka la barbar dhigo methylene chloride. Ku darida RFE ee koollada, waxay sababtaa falcelinta isku-tagga oo isku xirta substrate-ka, gaar ahaan qalabka caagga ah.
Xabagta laba qaybood ka kooban waa in la isticmaalaa gudaha muddada lagu dabaqi karo ka dib marka la geliyo RFE. Dhererka muddada lagu dabaqi karo ma aha oo kaliya la xidhiidha content polymer ee xabagta, laakiin sidoo kale qaybaha kale ee la xiriira (Sida reisn, antioxygen, plasticizer, dareere, iwm. Marka ku dhow in muddada lagu dabaqi karo, sida caadiga ah dhowr saacadood ama hal maalin shaqo, koolo waxay noqotaa mid aad u adag in la shaqeeyo, iyo viscosity kor u dhaqso, Ugu dambeyntii, waxay noqotaa jelly aan la beddeli karin.
RFE waxaa loo isticmaali karaa sidii xabag ahaan caag iyo biraha, iyo sidii wakiilka daawaynta crosslinking ee xabagta xal caag ah iyo xabagta polyurethane ku salaysan dareere.
Qadarka guud ahaan waa 4% ilaa 7% ee kor lagu soo sheegay xabagta ku salaysan dareeraha. Waxaa si gaar ah loo isticmaalaa isku xirka alaabada midab la'aanta ah ama midabka iftiinka leh.
Codsiga ay ku jiraan:
Ku xidhitaanka caag vulcanized (ama aan la daboolin) iyo PVC, PU, SBS iyo polymers kale isku xidhka walxaha iyo biraha (birta / aluminium).
- Sida wakiilka daweynta ee xabagta neoprene si loo hagaajiyo xoogga isku xidhka; wakiilka daweynta caagga iyo isku xidhka dharka.
- Sida wakiilka iskutallaabta ah ee qaybaha hydroxyl ee alaabta polyurethane (elastomers, dahaarka, iwm.).
- Sida wakiilka isku-dhafan ee loogu talagalay koolada polyurethane ee hydroxyl-la joojiyey ee loo isticmaalo warshadaha kabaha, taas oo hagaajin karta xoogga xajinta bilawga, caabbinta kulaylka iyo tilmaamayaasha kale.
- Inta badan lagu dabaqo kabo, shandad, warshadaha bacaha si loogu xidho dharka PVC iyo/ama PU.
Ku talin qiyaasta:
Iyada oo ku xidhan habka isku-xidhka iyo substrates, qiyaasta ugu habboon ayaa lagula talinayaa noocyo kala duwan oo ikhtiyaari ah.
Si loo daweeyo xabagta 100 qaybood miisaan ahaan (pbw) oo ku salaysan:
Graft-Chloroprene caag (waxa ka kooban caag qiyaastii. 16%): 3%-5% pbw RFE
Chloroprene caag (ka kooban caag qiyaastii. 20%): 5%-7% pbw RFE
Hydroxyl polyurethane (ka kooban polyurethane qiyaastii. 15%): 3%-5% pbw RFE
La jaanqaadka dareerayaasha:
RFE-keena waxaa lagu qasi karaa anhydrous iyo aalkolada aan lahayn ethyl acetate dichloropropane, trichlorethylene, acetone, methyl ethyl ketone, toluene iyo dareerayaal kale. Ku darista qaybo aad u badan oo ah hydrocarbons aliphatic waxay keeni kartaa turbidity. Si kastaba ha noqotee, xalka hydrocarbons aliphatic ee caagga dabiiciga ah (NR) wuxuu muujinayaa waafaqid wanaagsan RFE. Sidaa darteed, looma baahna in lagu daro dareerayaal kale.
Baakad:
Nooca 1. 750g/dhalo, 20 dhalo oo hal kartoon ah, 24 ama 30 kartoon oo hal baaldi ah;
Nooca 2. 20kg/durbaan, 18 durbaan ama 27 durbaan oo ku jira hal palette;
Ku qor 3. 55kg/durbaan, 8 ama 12 durbaan hal palette ah;
Nooca 4. 180kg / durbaan, 4 durbaan oo ku jira hal palette
Kaydinta:
Fadlan ku kaydi weelka asalka ah ee la shaabadeeyey 5℃-32℃, alaabta waxaa lagu ilaalin karaa xasilloon 12 aboor.
Dhammaan alaabtayada taxanaha ah waxay aad ugu nugul yihiin qoyaanka; Waxay soo saari doontaa kaarboon laba ogsaydh iyo urea aan milmi karin marka ay fal-celinta biyaha Haddi ay soo gaadho hawada ama/iyo iftiinka, waxa ay dedejin doontaa isbeddelada midabka ee alaabta.
(Laakin shaqada la taaban karo ayaa saameyn doonta.)
Badbaadada:
Dabeecadda khatarta ah, oo aad u gubanaysa, waxay kicisaa indhaha, haddii la nuugo waxay keeni kartaa xasaasiyad. Taabashada soo noqnoqda waxay keeni kartaa in maqaarku qallalo ama waalan. Uumiga alaabadu waxay qofka ka dhigi kartaa daal iyo vertigo.
