Isticmaalka
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) waa isku-dhis dabiici ah, dariiqyada ugu muhiimsan ee loo adeegsadona waa sidan soo socota:
- Isku-darka Agabka Polyurethane: MOCA waa qalab muhiim u ah fidinta silsiladda ee polyurethane. Soo saarista polyurethane, isocyanate prepolymers waxay u baahan yihiin inay la falgalaan fidiyeyaasha silsiladda si ay u sameeyaan polymers polyurethane oo miisaankoodu sareeyo. MOCA waxay leedahay falcelin sare oo leh isocyanates, taas oo si wax ku ool ah u fidin karta silsiladda molecular polyurethane waxayna hagaajin kartaa adkaanta, xoogga, iska caabbinta xirashada, iska caabbinta jeexjeexa iyo sifooyinka kale ee maaddada. Waxaa si caadi ah loogu isticmaalaa soo saarista alaabada elastomer polyurethane ee culeyska badan leh, sida saxannada shaandhada, duubayaasha caagga ah, shaabadadaha, iwm. ee loo isticmaalo warshadaha sida macdanta, birta, iyo batroolka. Badeecadahani waxay u baahan yihiin inay yeeshaan iska caabbin wanaagsan iyo sifooyin farsamo.
- Wakiilka Daaweynta Resins-ka Epoxy: MOCA waxaa loo isticmaali karaa sidii wakiil daaweyn resins-ka epoxy. Waxay martaa falcelin isku-xidhan oo leh resins epoxy si ay u sameeyaan qaab-dhismeed shabakadeed oo saddex-cabbir ah, sidaas darteedna waxay daaweysaa resins-ka epoxy-ga. Resins-ka epoxy-ga ee la daaweeyay waxay leeyihiin sifooyin farsamo oo wanaagsan, iska caabinta daxalka kiimikada, iyo iska caabinta kulaylka. Badanaa waxaa loo isticmaalaa soo saarista qaar ka mid ah isku-dhafka epoxy-ga oo leh shuruudo waxqabad sare leh, sida beeraha qalabka dheriga elektaroonigga ah iyo dahaarka dabaqa. Qalabka dheriga elektaroonigga ah wuxuu u baahan yahay inuu ka ilaaliyo qaybaha elektaroonigga ah ee gudaha deegaanka dibadda. Resin epoxy-ga ee la daaweeyay iyadoo ka qayb qaadanaysa MOCA wuxuu bixin karaa shaabad wanaagsan iyo ilaalin farsamo. Dahaarka dabaqa Epoxy wuxuu u baahan yahay inuu yeesho sifooyin sida iska caabinta xirashada iyo iska caabinta daxalka si uu u daboolo shuruudaha isticmaalka meelaha sida aqoon-is-weydaarsiyada warshadaha iyo goobaha baabuurta la dhigto.
