Tianjin Gnee Biotech Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm catalyst polyethylene nqi tsim nyog cas 9002-98-6 hauv Suav teb. Txais tos mus yuav cov khoom siv tshuaj pheej yig muag ntawm no los ntawm peb lub hoobkas. Rau nqe kev sab laj, tiv tauj peb.

Cov khoom ntawm Polyethyleneimine
Polyethyleneimine (PEI) yog cov khoom siv hluavtaws nrog cov yam ntxwv sib txawv. Nws muaj nyob rau hauv ob hom: linear thiab branched. Hauv nws lub cev lub cev, PEI feem ntau yog xim tsis muaj xim lossis daj ntseg - kua dej daj. Nws yog hygroscopic heev, yooj yim nqus dej los ntawm huab cua. PEI qhia tau zoo heev solubility nyob rau hauv dej thiab ethanol, tab sis nws yog insoluble nyob rau hauv benzene Nws aqueous daws yog cationic; a 5% aqueous tov feem ntau muaj pH tus nqi nyob rau hauv thaj tsam ntawm 8 - 11. Nyob rau hauv cov nqe lus ntawm tshuaj reactivity, PEI muaj siab reactivity vim nws ntau amine pawg. Cov pab pawg amine no tuaj yeem koom nrog ntau yam tshuaj lom neeg

Cov ntawv thov

Polyethyleneimine pom cov ntawv thov thoob plaws hauv ntau qhov kev lag luam. Hauv kev lag luam ntawv, nws ua haujlwm raws li kev tuav pov hwm thiab kev pabcuam dej. Nws tuaj yeem txhim kho lub zog ntub ntawm cov ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv tsis yog - qhov loj ntawm cov ntaub ntawv zoo li cov ntawv lim, cov ntaub ntawv blotting, thiab cov ntaub ntawv tso quav. Tsis tas li ntawd, nws tuaj yeem ua kom pom cov ntaub ntawv ntawm daim ntawv thiab ua rau lub flocculation ntawm cov fibers zoo hauv dej dawb. Hauv kev kho dej, PEI ua haujlwm raws li kev qhia meej. Nws qhov xwm txheej cationic tso cai rau nws cuam tshuam nrog cov khoom tsis zoo hauv dej, ua kom yooj yim rau lawv kev sib sau thiab tshem tawm. Hauv kev xa cov noob, PEI tau tshawb nrhiav los ua tus neeg sawv cev hloov pauv. Nws lub siab cationic charge density enables nws los tsim cov complexes zoo nrog nucleic acids zoo. Cov complexes no tuaj yeem nkag mus rau cov hlwb, xa cov khoom siv caj ces. Hauv huab cua purification, PEI tuaj yeem siv los ua ib qho adsorbent rau acidic gases, ozone, thiab aldehydes. Nws cov pab pawg amine tuaj yeem hnov ​​​​mob nrog cov tshuaj no, tshem tawm ntawm huab cua.
