Polyethylene (PEI)yog dej-soluble polymer. Cov concentration hauv dej ntawm cov khoom lag luam feem ntau yog 20% mus rau 50%. PEI yog polymerized los ntawm ethylene imide monomer. Nws yog ib qho cationic polymer uas feem ntau tshwm sim raws li cov xim tsis muaj xim rau cov kua daj lossis cov khoom nrog ntau yam ntawm qhov hnyav thiab cov qauv sib txawv.

Dab tsi yogpolyethyleneiminemuaj nuj nqi?
1. High adhesion, siab absorption amino pawg tuaj yeem hnov mob nrog hydroxyl pawg los tsim hydrogen daim ntawv cog lus, amine pab pawg tuaj yeem ua rau cov pab pawg carboxyl los ua ionic daim ntawv cog lus, amine pawg kuj tuaj yeem hnov mob nrog carbon acyl pawg los ua covalent daim ntawv cog lus. Nyob rau tib lub sijhawm, vim nws pawg polar (amine) thiab pawg hydrophobic (vinyl) qauv, nws tuaj yeem ua ke nrog cov khoom sib txawv. Nrog rau cov kev sib txuas ua ke no, nws tuaj yeem siv dav hauv kev sib khi, number case, xim, binder thiab lwm yam.
2. High-cationic polyvinyl imide muaj nyob rau hauv daim ntawv ntawm polycation nyob rau hauv dej, uas yuav neutralize thiab adsorb tag nrho cov anionic tshuaj. Nws kuj chelates hnyav hlau ions. Nrog nws cov khoom cationic siab, nws tuaj yeem siv rau hauv papermaking, dej kho, plating tov, dispersant thiab lwm yam.
3. Highly reactive polyethylenimine vim yog cov reactive thawj thiab theem nrab amines, yog li nws muaj peev xwm yooj yim react nrog epoxy, acids, isocyanate tebchaw thiab acid gases. Siv cov cuab yeej no, nws tuaj yeem siv los ua epoxy reactant, ib qho aldehyde adsorbent thiab kho xim.
Polyethylene yog siv rau dab tsi?
Polyethylene (PEI)yog ntau yam polymer compound nrog ntau yam kev siv, suav nrog tab sis tsis txwv rau:
1. Kev kho dej thiab kev lag luam ntawv. Raws li tus neeg saib xyuas lub zog ntub dej, nws yog siv rau hauv cov ntawv tsis muaj dej tsis zoo (xws li cov ntawv lim, cov ntawv lim dej, ntawv tso quav, thiab lwm yam), uas tuaj yeem txhim kho lub zog ntub ntawm daim ntawv thiab txo qhov kev puas tsuaj ntawm cov ntawv ua, thaum ua kom ceev cov ntaub ntawv. dej pom ntawm pulp thiab ua cov fibers zoo yooj yim rau flocculate.
2. Xim kho tus neeg saib xyuas. Nws muaj lub zog ruaj khov rau cov kua qaub dyes thiab tuaj yeem siv los kho tus neeg sawv cev thaum acid dyes dye ntawv.
3. Fiber hloov thiab dyeing auxiliaries. Rau kev kho fiber ntau, xws li lub cev armor, anti-txiav hnab looj tes, hlua, thiab lwm yam.
4. Cov khoom siv hluav taws xob. Hauv kev lag luam hluav taws xob, polyethylene imide zaj duab xis tuaj yeem siv los ua cov txheej txheem cais, cov khoom siv insulating thiab npog txheej ntawm cov khoom siv hluav taws xob, thiab lwm yam, nrog rau kev ua haujlwm zoo rwb thaiv tsev thiab kub tsis kam.
5. Ntim khoom noj. Raws li cov khoom ntim khoom noj, nws muaj qhov zoo ntawm cov dej noo-pov thawj, zoo roj tsis kam, tsis muaj tshuaj lom, tsis qab, kub tsis kam, thiab lwm yam, thiab yog dav siv hauv ntim cov nqaij, nqaij qaib, txiv hmab txiv ntoo, zaub, kas fes thiab lwm yam khoom.
6. Cov ntaub ntawv kho mob. Polyvinylimine tuaj yeem siv rau hauv cov khoom siv kho mob, cov cuab yeej kuaj mob, ntim tshuaj kho mob, thiab lwm yam, xws li kev hnav khaub ncaws kho mob thiab kev kho mob pob tshab zaj duab xis.
7. Adhesive. Raws li cov nplaum ua haujlwm siab, nws yog siv rau hauv kev tsim khoom ntawm aerospace, cov khoom siv hluav taws xob, cov khoom siv tsheb thiab lwm yam.
8. Cov tshuaj kho dej thiab cov tshuaj dispersants. Nws yog dav siv nyob rau hauv papermaking dej kho, electroplating kua, dispersant thiab lwm yam teb. Cov neeg nqa khoom. Polyvinylimide yog cov kab mob uas tsis yog kab mob rau kev xa cov noob, tshwj xeeb tshaj yog tsim rau kev sib kis ntawm ntau cov plasmids.
Ntxiv rau,polyethylenekuj muaj cov yam ntxwv ntawm siab adhesion, siab adsorption, siab cation, siab reactivity, thiab lwm yam, thiab nws kuj yog dav siv nyob rau hauv cov xim, number case, nplaum, fiber ntau kho, dej phwj tuaj thiab lwm yam.
Feem ntau, polyvinylimide yog ntau yam polymer nrog ntau yam kev siv, thiab nws cov khoom tuaj yeem hloov kho thiab ua kom zoo los ntawm kev hloov pauv qhov hnyav, qauv thiab kev ua haujlwm.
