MW800 MW 3500 Polyethylenimine CAS 25987-06-8 nrog rau qhov nruab nrab ntawm ceg Mw ~ 800 los ntawm LS, qhov nruab nrab Mn ~ 600 los ntawm GPC
Polyethylenimine yog ib hom polyamine uas yaj tau hauv dej. Vim muaj cov nitrogen atoms nplua nuj nyob rau ntawm cov saw hlau macromolecular, polyethylenimine muaj zog protophilicity, yog li nws muaj ntau yam kev siv, xws li ua flocculant hauv kev ua ntawv thiab pulping teb, adsorption ntawm cov hlau ions hauv kev kho dej teb, cationic polymer non viral gene carrier hauv kev kho mob, thiab lwm yam.

1. Hauv kev lag luam ntawv, polyethylenimine yog siv los ua tus pabcuam, tus neeg sib koom tes thiab tus neeg lim dej.
2. Hauv kev lag luam fiber, polyethylenimine yog siv los ua tus neeg sawv cev ntub dej, kev kho mob tiv thaiv hluav taws xob, kev ua kom tsis txhob muaj hluav taws, kev tiv thaiv ntsws, kev txhim kho xim, thiab lwm yam.
3. Siv rau cov txheej txheej, cov kua mem, cov nplaum (xws li kev vuam kub thiab cov ntim yas) tuaj yeem txhawb kev sib txuas, kev tiv thaiv kev nkag, txhim kho cov xim thiab cov khoom sib xyaw, tiv thaiv polymerization, txhim kho kev ruaj khov ntawm txheej, thiab lwm yam.
4. Siv rau hauv cov tshuaj pleev ib ce tuaj yeem txhim kho cov plaub hau zoo, antibacterial thiab mos tawv nqaij.
5. Hauv kev siv roj thiab kev ua haujlwm tob hauv qhov dej, polyethylenimine tuaj yeem tiv thaiv kev poob kua, txo qhov viscosity, tiv thaiv kev tso paraffin, thiab txhim kho kev ruaj khov ntawm av nplaum.
6. Nws siv tau rau hauv kev kho mob thiab tshuaj kom txhim kho kev sib raug zoo ntawm cov kabmob cuav thiab cov ntshav. Polyethylenimine kuj tseem siv tau ua ib txheej rau cov khoom siv kho mob.
7. Ntxiv rau, polyethylenimine kuj yog ib feem ntawm ion exchange resin thiab exchange membrane, resin crosslinking agent, crystallization agent, electroplating gloss agent, hlau xeb inhibitor, roj av thiab diesel combustion supporting agent, lubricating roj additive, iav ntxuav agent, kua chromatography stationary phase, polymer catalyst, thiab lwm yam. polyethylenimine kuj tseem siv rau hauv kev kawm txog cov qauv enzyme synthetic.
Ntim nws hauv 25kgs nruas thiab khaws cia kom deb ntawm lub teeb ntawm qhov kub hauv qab 25 ℃.
