A cikin samar da polyurethane, mafi mahimmancin halayen sinadaran shine tsakanin isocyanates da polyols. Kamar yadda aka sani, isocyanates suna da matukar damuwa ga danshi, har ma da gano yawan danshi zai amsa tare da isocyanates don samar da carbon dioxide, yana haifar da kumfa, rashin daidaituwa da matsalolin da suka danganci.
A matsayin ƙari na sinadarai, mai lalata danshi shine muhimmin abu a cikin tsarin polyurethane. An tsara shi don amsawa tare da cire danshi daga albarkatun ƙasa ko yanayin da ke kewaye da shi don hana shi daga amsawa tare da isocyanates a cikin tsarin polyurethane.
Zeolite Molecular Sieve Ga Polyurethane Moisture Scavenger
Zeolite kwayoyin sieve yana da kyakkyawan kwanciyar hankali na sinadarai, kuma ita kanta ba zata amsa da isocyanates ko polyols ba. Duk da haka, yana iya yadda ya kamata da kuma zaɓin yaɗa danshi a cikin ƙirar polyurethane na al'ada, yana hana abin da ya faru na halayen lalacewa.
Zeolite kwayoyin sieve amfani da polyurethane danshi scavengers yawanci a foda form, wanda kuma ake kira kunna zeolite foda ko kwayoyin sieve kunna foda.
