MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), oo sidoo kale loo yaqaan MOCA, waa walax loo isticmaalo sidii wakiilka iskutallaabta / silsiladaha fidiyaha ee alaabada poliurethane, gaar ahaan loogu talagalay elastomer polyurethane (CPU). Elastomers Polyurethane waa dabacsanaan iyo dabeecad dabacsanaan sida caag laakiin leh sifooyin muhiim ah, waxay isku daraysaa balaastiga sare ee caag iyo qallafsanaanta balaastikada. MOCA waxay leedahay xasilloonida midabka heerkulka sare. Elastomers MOCA-saldhig waxay u fiican yihiin nabarka / saamaynta / kiimikaadka / saliidda / ozone iyo iska caabbinta qabow, dabacsanaanta dhib la'aan la'aanteed adag ama hoose (Qiimeynta Shore A ilaa Shore D), adkaysiga sare / jeexjeexa / xoogga cadaadiska, iyo nuugista gariirka. Nolosha dheriga dheer, aad ayay u fududahay in lagu maareeyo, xitaa waxaad ku maarayn kartaa gacanta halkii aad ka isticmaali lahayd mashiinada. Iyada oo ka dhalatay sifooyinkaas jireed iyo faa'iidooyinka, MOCA waa isku-xidhka ugu caansan / silsiladaha fidiyaha ee elastomer urethane (Nidaamka TDI). Dhanka kale, sidoo kale waa wakiilka daaweynta caalamiga ah ee alaabta Epoxy.
Marka la barbardhigo DETDA & DMTDA, waxaa jira faa'iidooyin muuqda oo MOCA ah sida soo socota.
1. Alaabta la dhammeeyey waa midab khafiif ah.
2. MOCA waa nooc adag, sidaas darteed, aad bay u fududahay in la kaydiyo oo ay yaraato wasakhowga.
3. Si fudud wax looga qaban karo. Nolosha dheri dheer.
4. Modulku wuu sarreeyaa.
5. Qiimaha hoose.
MOCA waa fidiyaha silsiladda diamine-ka udgoon ee caanka ah ama wakiilka daaweeyaha ee shubida kolayga polyurethane (PU). Elastomers MOCA-base waxay leeyihiin sifooyin aad u fiican, waxaa si ballaaran loo isticmaalaa meelo kala duwan oo ay ka mid yihiin dhismaha, dhismaha, baabuurta, macdanta, semi-conductor, epoxy, xarunta ciyaaraha iyo wixii la mid ah.
1. Isku xidhka wakiilka warshadaha elektiroonigga ah.
2. Qalabka aan biyuhu lahayn / daahan ee dhismaha & warshadaha dhismaha.
3. Silsiladda fidiyaha ee elastomers PU, ie isku xirka caagga daanka, caarada PU.
4. Walaxda daawaynta resin epoxy.
5. Qaybaha isticmaalka warshadaha, ie, suumanka wax qaada, shubayaasha, rollers-ka, isku xidhka.
6. Pads nuugista naxdinta ee warshadaha baabuurta.
7. Daabacaadda rollers, garbaha durbaanka, garbaha wax lagu nadiifiyo, daabka xoqida ee warshadaha daabacaadda.
8. Shaabadeynta.
9. Qalabka dahaarka Epoxy.
10. xaashida kaadi mareenka bakteeriyada.
11. Shaashada kala soocida macdanta.
12. Dhuumaha dahaarka.
