Polyurethane ke eng?

Lebitso le felletseng la polyurethane ke polyurethane, e leng lentsoe le akaretsang bakeng sa metsoako ea macromolecular e nang le lihlopha tse pheta-phetoang tsa urethane ketane e kholo.Polyurethane ke sehlotšoana sa urethane naheng ea heso, hape e ka ba le ether ester urea biuret urea sehlopha sa pele sa selelekela sa polyurethane.E entsoe ka polyaddition ea organic diisocyanate kapa polyisocyanate le dihydroxyl kapa polyhydroxyl motsoako.Polyurethane e na le lisebelisoa tse ngata, e ka nka sebaka sa rabara, polasetiki, nylon, joalo-joalo, e sebelisoang boema-fofane, lihotele, thepa ea kaho, lifeme tsa likoloi, merafo ea mashala, lifeme tsa samente, lifolete tse phahameng, matlo a bolulo, mapolanka, lejoe le mebala. bonono, phaka jj.

Mosebetsi oa polyurethane:

Polyurethane e ka sebelisoa ha ho etsoa lipolasetiki, rabara, likhoele, foam tse thata le tse tenyetsehang, likhomaretsi le liphahlo, joalo-joalo. E ka sebelisoa mafapheng a fapaneng a bophelo ba batho mme e na le lits'ebetso tse fapaneng.

1. Foam ea polyurethane: e arotsoe ka foam e thata ea polyurethane, foam e thata-thata ea polyurethane le foam e bonolo ea polyurethane.Foam e thata ea polyurethane e sebelisoa haholo bakeng sa ho aha lisebelisoa tsa ho kenya mogote, lisebelisoa tsa ho futhumatsa mocheso (mocheso oa ho kenya liphaephe, joalo-joalo), litlhoko tsa letsatsi le letsatsi (libethe, li-sofa, joalo-joalo, li-pads, lihatsetsi, li-air conditioner, joalo-joalo. , joalo-joalo lisebelisoa tsa mantlha. ), le lipalangoang (lisebelisoa tse kang li-cushion le siling bakeng sa likoloi, lifofane, le likoloi tsa terene).

2. Polyurethane elastomer: Polyurethane elastomer e na le melemo ea matla a matle a matla, matla a ho taboha, ho hanyetsa tšusumetso, ho hanyetsa abrasion, ho hanyetsa boemo ba leholimo, ho hanyetsa hydrolysis, ho hanyetsa oli joalo-joalo.Haholo-holo e sebelisoa bakeng sa lisebelisoa tsa ho roala (tse kang tšireletso ea li-hoses, li-washer, lithaere, li-roller, li-gear, liphaephe, joalo-joalo), li-insulators, lieta le lithaere tse tiileng.

3. Lintho tse sa keneleng metsi tsa polyurethane: Lintho tse sa keneleng metsi tsa polyurethane li bonolo haholo ho li sebelisa.E ka kopanngoa le ho roala setšeng 'me ea phekoloa ka mocheso o tloaelehileng le mongobo,' me lesela le sa keneleng metsi le se nang seams, elasticity ea rabara le ts'ebetso e ntle e ka fumanoa.'Me ho bonolo ho e lokisa ka mor'a tšenyo.Ka kakaretso e sebelisoa e le lisebelisoa tsa ho betla, lisebelisoa tsa pina le lebaleng, mabelo a mabelo, lisebelisoa tsa sebaka sa boikhathollo, liforeimi tsa lifensetere tse futhumatsang mocheso, jj.

4. Ho roala ha polyurethane: Ho roala ha polyurethane ho na le sekhomaretsi se matla, 'me filimi ea ho roala e na le ho hanyetsa ho hoholo ha metsi, ho hanyetsa metsi le lik'hemik'hale.Haholo-holo e sebelisetsoa ho roala thepa ea ka tlung, liaparo tsa thepa ea mohaho le li-inks tsa khatiso tsa indasteri.

5. Sekhomaretsi sa polyurethane: Ts'ebetso ea sehlahisoa se phekotsoeng e ka fetoloa ka ho fetola karo-karolelano ea isocyanate le polyol, e le hore e ka finyella ho khomarela ka holimo ho substrate, ho hanyetsa metsi ho babatsehang, ho hanyetsa oli le lik'hemik'hale tsa lik'hemik'hale.Likhomaretsi tsa polyurethane li sebelisoa haholo ho paka, ho haha, lehong, koloi, ho etsa lieta le liindasteri tse ling.

6. Lisebelisoa tsa likokoana-hloko: Polyurethane e na le biocompatibility e babatsehang, kahoo butle-butle e sebelisoa haholo e le lisebelisoa tsa tlhaho.E ka sebelisoa ha ho etsoa li-pacemaker tsa pelo ea maiketsetso, methapo ea mali ea maiketsetso, masapo a maiketsetso, esophagus ea maiketsetso, liphio tsa maiketsetso, li-membrane tsa maiketsetso tsa dialysis, jj.

Lintlha tse ka holimo ke tse ling tsa lintlha tsa bohlokoa mabapi le hore na thepa ea polyurethane ke eng le karolo ea polyurethane eo mohlophisi a u hlophiselitseng eona.Polyurethane butle-butle e fumana sebaka se tiileng 'marakeng oa thepa ea mohaho ka lebaka la khanyetso ea eona ea pele le litšobotsi tse ling.Basebelisi ba marang-rang ba ka reka ho latela litlhoko tsa bona tsa ntlafatso ea lehae.
