Kini o mọ nipa polyurea?

Polyurea jẹ nkan elastomeric ti a ṣẹda nipasẹ iṣesi ti awọn paati isocyanate ati awọn agbo ogun amino. Ti pin si polyurea mimọ ati polyurea, awọn abuda wọn kii ṣe kanna, awọn abuda akọkọ ti polyurea jẹ aabo ipata, resistance omi, resistance resistance, bbl

Kilasi ti awọn agbo ogun ti o ṣẹda nipasẹ iṣesi ti paati isocyanate pẹlu agbo-ara amino kan. Awọn paati isocyanate le jẹ awọn monomers, awọn polima, awọn itọsẹ isocyanate, prepolymers, ati ologbele-prepolymers.

Polyurea jẹ polyamide carbonated ati pe o jẹ afiwera si polycarbonate, eyiti o jẹ polyester carbonated. Polarity ti ẹgbẹ urea jẹ nla, ati pe awọn ifunmọ hydrogen diẹ sii ni a le ṣẹda, nitorinaa aaye yo ti polyurea ga ju ti polyamide ti o baamu, ati pe agbara tun jẹ nla, eyiti o dara fun awọn okun asọ.

Ọna ti o dara julọ lati ṣajọpọ polyurea ni lati yipada si ọna iṣelọpọ polyurethane, eyini ni, ifarahan ti amine alakomeji ati diisocyanate. Idahun exothermic le tuka nipasẹ polymerization ojutu tabi polymerization interfacial. ko si awọn aati ẹgbẹ, ilana polymerization jẹ irọrun ti o rọrun. Fun apẹẹrẹ, aaye yo ti 2,4-toluene diisocyanate ati 4,4'-diaminodiphenyl ether de 320 ℃.

Polyurea ti wa ni lilo pupọ ni awọn agbegbe wọnyi: aabo nja 60%, aṣọ-iṣọ sooro ti awọn oko nla 15%, aabo ipata ti awọn ẹya irin 10%, aabo omi orule 10%, awọn miiran 5%.

Gẹgẹbi imọ-ẹrọ aabo, imọ-ẹrọ polyurea ni a lo ni akọkọ ni awọn agbegbe mẹrin: aabo omi, aabo ipata, abrasion ati ipari dada. Fun apẹẹrẹ, lilo polyurea fun aabo ipata ni awọn opo gigun ti epo tun jẹ ohun elo imọ-ẹrọ akọkọ ati ti o tobi julọ ti imọ-ẹrọ polyurea. Awọn ohun elo ni awọn aaye miiran tun pẹlu egboogi-ibajẹ ti awọn ẹya irin (paapaa-ipata ti awọn piles irin ti awọn berths), awọn ohun elo ijagba rirọ (buoy okun, okun), aabo ti awọn ohun elo agbara iparun, ile-iṣẹ aabo orilẹ-ede ( chassis ojò, bulletproof ibori), awọn adagun odo, ati bẹbẹ lọ….
