PTSI p-toluenesulfonyl isocyanate CAS 4083-64-1 Tosyl isocyanate
MSI (PTSI), p-toluenesulfonyl isocyanate, monoisocyanate yomwe imagwiritsidwa ntchito kwambiri, chinthu chomwe chimagwira ntchito kwambiri chomwe chimagwiritsidwa ntchito kwambiri ngati chochotsera madzi m'zinthu za mankhwala, monga zosungunulira, zodzaza, utoto ndi malo a phula. Pokhala chosungira chinyezi cha zophimba za polyurethane (PU) zosungunulira, zomatira, zomatira komanso ngati pakati pa mankhwala osiyanasiyana ofunikira m'mafakitale.
P-toluenesulfonyl isocyanate (PTSI) imaletsa kupangika kosafunikira kwa utoto ndi utoto, motero, imalola opanga kupanga kupanga ma polyurethane apamwamba kwambiri. Pogwiritsa ntchito PTSI popanga utoto wa polyurethane, kutayika kwa thovu lowala, lachikasu komanso lochitapo kanthu chifukwa cha pamwamba pamadzi m'dongosolo lonse kumachepa. P-toluenesulfonyl isocyanate ingakhalenso chowonjezera chokhazikika pazinthu zoziziritsa chinyezi kuti zisawonongeke kapena/ndi kusintha mtundu pamene zikusungidwa.
MSI (PTSI) imakumana ndi madzi, zomwe zimapangitsa kuti mpweya wa carbon dioxide upangidwe ndipo zimapangitsa kuti zinthu zomwe zimasungunuka mu utoto wamba zipangidwe. Pafupifupi 12g ya stabilizer ndiyofunikira kuti igwirizane ndi 1g ya madzi. Komabe, zomwe zachitika zasonyeza kuti izi zimagwira ntchito bwino kwambiri ngati pali MSI (PTSI) yochulukirapo. Kugwirizana ndi zomangira utoto kuyenera kuyesedwa nthawi zonse pasadakhale.
P-toluenesulfonyl isocyanate ikulimbikitsidwa kuti igwiritsidwe ntchito ngati chochotsera unyolo panthawi ya polymerization komanso ngati chochotsera magulu osafunikira ogwira ntchito muzinthu zopangira za PU. Mu malasha tar PU zokutira, MSI ingagwiritsidwe ntchito kuletsa ma amine ndi magulu ogwira ntchito a OH ndikuchotsa madzi mu tar kuti apewe thovu ndi gelation isanafike nthawi yomwe tar ikasakanizidwa ndi PU prepolymer.
Mawonekedwe:
- Zimachotsa zotsatira za chinyezi ndipo zimaletsa mavuto okhudzana ndi chinyezi mu zokutira za polyurethane
- Kukhuthala kochepa, isocyanate imodzi yomwe imagwira ntchito mwa mankhwala imachita ndi madzi kuti ipange amide yopanda mphamvu
- Amagwiritsidwa ntchito pochotsa madzi m'madzi osungunuka, zodzaza, utoto ndi bituminous tars
- Zimathandiza kuti ma diisocyanates asungidwe bwino kuti asawonongeke kapena kusokonekera.
- Amachotsa chinyezi chomwe chimayambitsidwa ndi zosungunulira, utoto, ndi zodzaza mu makina a PU a single-component ndi Dual-component
MSI (PTSI) imagwiritsidwa ntchito ngati chokhazikika pa zinthu zochiritsira chinyezi. Imaletsa kupangika kosafunikira kwa utoto ndi utoto msanga. P-toluenesulfonyl isocyanat imagwiritsidwa ntchito nthawi zambiri m'malo otsatirawa:
- Ma polyurethane okhala ndi zinthu ziwiri zomatira ndi zomatira.
- Zophimba ndi utoto wa polyurethane wokhala ndi gawo limodzi ndi magawo awiri.
- Zosungunulira
- Utoto
- Zodzaza
- Zothandizira

Kusunga ndi Kunyamula: PTSI imakhudzidwa ndi chinyezi ndipo nthawi zonse iyenera kusungidwa m'zidebe zoyambirira zotsekedwa bwino kutentha kwa pakati pa 5°C ndi 30°C. Zidebe zikatsegulidwa, ziyenera kutsekedwanso nthawi yomweyo mutachotsa chinthucho. Sungani kutali ndi mowa, maziko olimba, ma amine, ndi zinthu zamphamvu zophikira.
Nthawi yosungiramo zinthu: Miyezi 6 kuyambira tsiku lopangira.
