PTSI p-toluenesulfonyl isocyanate CAS 4083-64-1 Tosyl isocyanate
MSI (PTSI), p-toluenesulfonyl isocyanate, monoisocyanate da aka saba amfani da shi, wani fili mai amsawa sosai wanda ake amfani da shi azaman wakili na dehydrating a cikin samfuran sinadarai, kamar kaushi, cikawa, pigments da wuraren kwalta. Kasancewa mai lalata danshi don rufin polyurethane (PU) mai ƙarfi, masu ɗaukar hoto, adhesives kuma a matsayin tsaka-tsaki na mahimman mahimman masana'antu daban-daban.
p-toluenesulfonyl isocyanate (PTSI) yana hana abin da ba a so da wuri na zanen & shafi, saboda haka, yana ba da damar masu tsarawa don samar da polyurethane mai inganci. Ta amfani da PTSI wajen samar da fenti na polyurethane, asarar mai sheki, rawaya da kumfa mai amsawa ta hanyar rigar saman da ke cikin tsarin duk sun ragu. p-toluenesulfonyl isocyanate kuma na iya zama ƙari ga kayan aikin danshi don hana lalacewa ko/da canza launin yayin ajiya.
MSI (PTSI) yana amsawa da ruwa, yana ba da carbon dioxide kuma yana haifar da samuwar samfuran amsawa waɗanda ke narkewa a cikin ƙirar fenti na al'ada. Kusan 12g na stabilizer ana buƙatar a ka'idar don amsawa da 1g na ruwa. Kwarewa ta nuna, duk da haka, cewa matakin ya fi tasiri a gaban rarar MSI (PTSI). Ya kamata a gwada dacewa da masu ɗaure fenti koyaushe tukuna.
p-toluenesulfonyl isocyanate ana ba da shawarar yin amfani da shi azaman ƙarshen sarkar yayin polymerization kuma azaman mai cire ƙungiyoyin ayyukan da ba'a so a cikin albarkatun PU. A cikin rufin kwalta na PU, ana iya amfani da MSI don kawar da amines da ƙungiyoyin aikin OH da cire ruwa a cikin kwalta don guje wa kumfa da lokacin da ba a kai ba lokacin da aka haɗe tar da PU prepolymer.
Siffofin:
- Yana kawar da tasirin zafi kuma yana hana matsalolin danshi a cikin suturar polyurethane
- Low danko, monofunctional isocyanate wanda ke amsawa da ruwa don samar da inert amide.
- Ana amfani da shi don bushewar kaushi, filler, pigments da kwalta na bituminous
- Inganta kwanciyar hankali na diisocyanates akan bazuwar da canza launin
- Yana kawar da danshi da aka gabatar tare da kaushi, pigments, da filler a cikin Single-bangaren da Dual-bangaren PU tsarin.
Ana amfani da MSI (PTSI) azaman stabilizer don kayan warkar da danshi. Yana hana wanda ba'a so wanda bai kai ba na zanen & shafi. Ana amfani da p-toluenesulfonyl isocyanat azaman wurare masu zuwa:
- Single-bangare da Dual-bangaren polyurethane adhesives da sealants.
- Single-bangare da Dual-bangaren polyurethane shafi da fenti.
- Masu narkewa
