Polyethylenimine (PEI)ndi polima wosungunuka m'madzi. M'madzi azinthu zamalonda nthawi zambiri amakhala 20% mpaka 50%. PEI ndi polymerized kuchokera ku ethylene imide monomer. Ndi cationic polima yomwe nthawi zambiri imawoneka ngati madzi opanda mtundu mpaka achikasu kapena olimba okhala ndi kulemera kosiyanasiyana kwa mamolekyu ndi mitundu yosiyanasiyana yamapangidwe.

Ndi chiyanipolyethyleneiminentchito?

1. Kumamatira kwakukulu, kuyamwa kwakukulu kwa amino gulu lingathe kuchita ndi gulu la hydroxyl kuti lipange mgwirizano wa haidrojeni, gulu la amine likhoza kuchitapo kanthu ndi gulu la carboxyl kupanga mgwirizano wa ionic, gulu la amine lingathenso kuchitapo kanthu ndi gulu la carbon acyl kupanga covalent chomangira. Pa nthawi yomweyi, chifukwa cha gulu lake la polar (amine) ndi gulu la hydrophobic (vinyl), likhoza kuphatikizidwa ndi zinthu zosiyanasiyana. Ndi mphamvu zomangira zonsezi, zitha kugwiritsidwa ntchito kwambiri posindikiza, inki, utoto, binder ndi zina zotero.

2. High-cationic polyvinyl imide ilipo mu mawonekedwe a polycation m'madzi, yomwe imatha kusokoneza ndi kusokoneza zinthu zonse za anionic. Komanso chelates heavy metal ayoni. Ndi katundu wake mkulu cationic, angagwiritsidwe ntchito papermaking, mankhwala madzi, plating njira, dispersant ndi madera ena.

3. Polyethylenimine yogwira ntchito kwambiri chifukwa cha ma amines oyambirira ndi apamwamba kwambiri, kotero imatha kuchitapo kanthu mosavuta ndi epoxy, acids, isocyanate mankhwala ndi mpweya wa asidi. Pogwiritsa ntchito malowa, angagwiritsidwe ntchito ngati epoxy reactant, aldehyde adsorbent ndi wothandizira mtundu.

Kodi polyethylenimine imagwiritsidwa ntchito bwanji?

Polyethylenimine (PEI)ndi gulu la polima losunthika lomwe limagwiritsidwa ntchito mosiyanasiyana, kuphatikiza koma osalekezera ku:

1. Madzi opangira madzi ndi makampani opanga mapepala. Monga chonyowa champhamvu, chimagwiritsidwa ntchito pamapepala otsekemera a ungumed (monga pepala losefera, pepala lopukutira inki, pepala lakuchimbudzi, ndi zina), zomwe zimatha kupititsa patsogolo kunyowa kwa pepala ndikuchepetsa kuwonongeka kwamapepala, ndikufulumizitsa kusefera madzi kwa zamkati ndikupanga ulusi wabwino kuti ukhale wosavuta kuyandama.

2. Mtundu wokonza wothandizira. Ili ndi mphamvu yomanga yamphamvu ya utoto wa asidi ndipo imatha kugwiritsidwa ntchito ngati chokonzera pamene utoto wa asidi ukudaya pepala.

3. Kusintha kwa Fiber ndi zida zothandizira. Pochiza CHIKWANGWANI, monga zida za thupi, magolovesi odana ndi kudula, chingwe, etc.

4. Zida zamagetsi. M'munda wa zamagetsi, polyethylene imide filimu angagwiritsidwe ntchito ngati wosanjikiza kudzipatula, insulating zakuthupi ndi chophimba wosanjikiza zigawo zikuluzikulu zamagetsi, etc., ndi ntchito yabwino kutchinjiriza ndi mkulu kutentha kukana.

5. Kuyika chakudya. Monga zinthu zopangira chakudya, zimakhala ndi ubwino wokhala ndi chinyezi, kukana mpweya wabwino, zopanda poizoni, zopanda pake, kutentha kwambiri, etc., ndipo zimagwiritsidwa ntchito kwambiri popaka nyama, nkhuku, zipatso, masamba, khofi ndi mankhwala ena.

6. Zida zamankhwala. Polyvinylimine ingagwiritsidwe ntchito pazida zamankhwala, zida zowunikira, zotengera zamankhwala, ndi zina zambiri, monga zovala zamankhwala ndi mafilimu owonekera azachipatala.

7. Zomatira. Monga zomatira zapamwamba, zimagwiritsidwa ntchito popanga ndege, zida zamagetsi, zida zamagalimoto ndi zina zotero.

8. Mankhwala othandizira madzi ndi dispersants. Amagwiritsidwa ntchito kwambiri popangira madzi opangira mapepala, njira ya electroplating, dispersant ndi madera ena. Gene chonyamulira. Polyvinylimide ndi vekitala yopanda ma virus yoperekera majini, makamaka oyenera kupatsirana ma plasmids angapo.

Kuphatikiza apo,polyethylenimineilinso ndi mawonekedwe a zomatira kwambiri, kutengeka kwambiri, cation, high reactivity, etc., ndipo amagwiritsidwanso ntchito kwambiri pankhani ya utoto, inki, zomatira, zomatira, zokometsera za fiber, kuthira zimbudzi ndi zina zotero.

Nthawi zambiri, polyvinylimide ndi polima yosunthika yokhala ndi ntchito zambiri, ndipo mawonekedwe ake amatha kusinthidwa ndikuwongoleredwa posintha kulemera kwa maselo, kapangidwe kake ndi magwiridwe antchito.
