Stearyl Methacrylate CAS 32360-05-7
Stearyl Methacrylate ndi chinthu choyera, chonga phula chomwe sichisungunuka m'madzi ndipo chimakhala ndi fungo loipa. Fomula yake ya molekyulu ndi C₂₂H₄₂O₂, kulemera kwa molekyulu ndi 338.57, malo osungunuka ndi 18-20°C (lit.), malo owira ndi 195°C, kuchuluka kwa madzi ndi 0.864 g/mL pa 25°C (lit.), kuthamanga kwa nthunzi ndi 0.06 Pa pa 20°C, ndi refractive index n₂₀/D = 1.451 (lit.).
| CHINTHU | MUYENERERO |
| Zamkati | ≥99％ |
| Mtengo wa Asidi | ≤0.5% (kutengera asidi wa methacrylic) |
| Kuchuluka kwa Madzi | ≤0.2% |
| Mtundu | ≤80 (APHA) |
| Choletsa Kuphatikizika kwa Polymerization | 200-400 ppm MEHQ |
Kupanga inki, zokutira, zomatira, utoto ndi zomaliza nsalu, zothandizira chikopa, zoteteza madzi ndi zoletsa mafuta, zoletsa kuyenda kwa madzi, zowonjezera mafuta odzola, ndi zochepetsera kukhuthala kwa mafuta osakonzedwa.
1. Magwiridwe antchito awiri: Ili ndi ma bond awiri omwe amagwira ntchito kwambiri a methacrylate komanso gulu la alkyl long-chain C18, zomwe zimathandiza kuti pakhale polymerization ya free radical ndi copolymerization ndi ma monomers osiyanasiyana (monga acrylates, styrene, acrylonitrile, ndi zina zotero) kuti ipereke ntchito zatsopano ku polima.
2. Kutentha kochepa kwa galasi (Tg≈-100℃): Kumapereka kusinthasintha kwabwino kwambiri kwa kutentha kochepa, koyenera zipangizo zomwe zimapangidwira malo ozizira.
3. Kukhuthala kochepa: Kumapereka kuyenda bwino kwa zinthu zikagwiritsidwa ntchito ngati monomer, zomwe zimathandiza kusakaniza ndi kusamalira.
4. Kukhazikika kwa mankhwala: Kulimbana ndi hydrolysis, kumawonetsa kukhazikika kwa kutentha kwambiri, ndi flashpoint yokwera kufika 192℃, kuonetsetsa kuti pali chitetezo chabwino.
