Menene Tsarin Ayyukan Masu Ƙarfafa Amine akan Polyurethane?
Masu haɓaka sinadarin aminemuhimmin ɓangare ne na samar da polyurethane kuma muhimman abubuwan haɓakawa ne waɗanda ke hanzarta amsawar tsakanin polyols da isocyanates (babban abincin da ake amfani da shi don samar da kumfa polyurethane), suna sarrafawa da daidaita amsawar gel da kuma amsawar iskar gas ko kumfa wanda ke samar da kumfa. Suna yin hakan ta hanyar rage kuzarin kunnawa da ake buƙata don amsawar sinadarai, wanda ke haifar da faɗaɗa kumfa da ƙarfafawa cikin sauri da kuma sarrafawa. Masu haɓaka amine suna da tasiri musamman saboda suna shiga cikin amsawar, ƙungiyoyin amsawa a cikin tsarin kwayoyin halittarsu na iya hulɗa da isocyanates, kuma masu haɓaka amine galibi suna yin tsakanin 0.1% zuwa 5.0% na tsarin polyurethane. Wannan keɓantaccen abu yana ba su damar ɗaurewa zuwa polyisocyanates, suna daidaita matrix na polyurethane na ƙarshe kuma suna tabbatar da mannewa ga substrate.
Tsarin catalytic na amine catalyst a cikin kumfa polyurethane galibi yana haɓaka manyan halayen guda biyu: amsawar polyol-isocyanate (samfurin haɗin carbate) da amsawar isocyanate-ruwa (samar da carbon dioxide). Wannan martani na ƙarshe yana samar da kumfa, yana samar da tsarin ƙwayoyin halitta na kumfa. Ta hanyar wannan aiki biyu, mai haɓaka amine yana ba da damar daidaita tsarin kumfa da warkarwa, yana tabbatar da cewa kumfa yana faɗaɗa daidai yayin da yake ƙarfafawa zuwa tsari mai ƙarfi. Masu haɓaka kamarMXC-70kuma suna samar da santsi mai lanƙwasa daga sama, wanda ke nufin suna haɓaka ƙaruwa a hankali a cikin danko na kumfa. Wannan yana haifar da tsarin zuma mai tsari wanda ke taimakawa wajen inganta dorewa da kwanciyar hankali na kumfa.
Fagen Amfani da Masu Haɗa Amine
Ana amfani da sinadarin Amine wajen amfani da nau'ikan polyurethane iri-iri, ciki har da kumfa mai laushi da tauri, elastomers, coatings, manne, da sealants. A cikin samar da kumfa mai laushi, suna taimakawa wajen cimma laushi da sassauci da ake so, wanda hakan ya sa su dace da matashin kayan daki, kayan kwanciya da kujerun mota. Don aikace-aikacen kumfa mai tauri, kamar su bangarorin rufi, kayan aiki, da kumfa mai feshi, sinadarin amine yana haɓaka tsarin ƙwayoyin halitta masu yawa waɗanda ke haɓaka rufin zafi da kwanciyar hankali.
Masu haɓaka sinadarin Amine kamar MXC-70 sun dace musamman don amfani mai sauƙi saboda ƙarancin wari da kuma ƙarancin fitar da hayaki.
