Li-screen tsa polyurethane tse tloaelehileng haholo-holo li kenyelletsa li-screen tsa merafo ea polyurethane le li-screen tsa polyurethane dehydration. Lipoleiti tsa skrine tsa polyurethane li sebelisoa ho metallurgy (tšepe ea tšepe, lejoe la mokoetla, fluorite, cooling blast furnace slag, coke le thepa e tala e meng), litšepe tse seng tsa ferrous, mashala, lik'hemik'hale, thepa ea kaho le boenjiniere ba motlakase oa metsi, kalafo ea litšila tse khorofo, li-quarry le liindasteri tse ling. Merafo, tlhahlobo, ho hlophisa le liindasteri tse ling.
Tshebetso le litšobotsi tsa mantlha tsa poleiti ea sieve ea polyurethane ke:
1. Khanyetso e ntle ea ho khohlela, khanyetso ea eona ea ho khohlela e feta lipoleiti tsa tšepe tsa sefe ka makhetlo a 3 ho isa ho a 5 le ho feta lipoleiti tse tloaelehileng tsa sefe ea rabara ka makhetlo a fetang a 5.
2. Mosebetsi oa tlhokomelo o monyane, skrine ea polyurethane ha e senyehe habonolo, 'me bophelo ba tšebeletso bo bolelele, kahoo e ka fokotsa haholo palo ea tlhokomelo le tahlehelo ea tlhokomelo.
3. Litšenyehelo tsohle li tlase. Le hoja skrine ea polyurethane ea boholo bo lekanang (sebaka) e phahame hanngoe ho feta skrine ea tšepe e sa ruseng (hoo e ka bang makhetlo a 2), nako ea bophelo ba skrine ea polyurethane e feta ea skrine ea tšepe e sa ruseng ka makhetlo a 3 ho isa ho a 5, 'me palo ea tlhokomelo le sebaka e nkeloa sebaka. Kahoo litšenyehelo tsohle ha li holimo, 'me li theko e tlaase haholo.
4. Ho hanyetsa mongobo hantle, e ka sebetsa tlas'a boemo ba metsi e le sehatsetsi, 'me tlas'a boemo ba metsi, oli le mecha e meng ea phatlalatso, coefficient ea khohlano pakeng tsa polyurethane le thepa ea fokotseha, e leng se thusang haholo ho kenella ha skrine, se ntlafatsa katleho ea ho hlahloba, 'me se ka qoba likaroloana tse metsi. Ka nako e ts'oanang, ka lebaka la coefficient ea khohlano e fokotsehileng, ho tsofala hoa fokotseha 'me bophelo ba tšebeletso boa eketseha.
5. E hanela mafome ebile ha e chese.
6. Ka lebaka la moralo o utloahalang oa masoba a sefe le ts'ebetso e ikhethang ea tlhahiso ea poleiti ea sefe, likaroloana tsa boholo bo feteletseng li ke ke tsa thibela masoba a sefe.
7. Tshebetso e ntle ya ho monya thothomelo, bokgoni bo matla ba ho fokotsa lerata, e ka fokotsa lerata, mme ya etsa hore thepa ya skrine e se ke ya robeha habonolo nakong ya tshebetso ya thothomelo.
8. Ka lebaka la litšobotsi tsa ho thothomela ha polyurethane, skrine ea polyurethane e na le phello ea ho itlhoekisa, kahoo bokhoni ba ho hlahloba bo holimo.
9. Phokotso ea ho boloka matla le tšebeliso. Polyurethane e na le matla a khoheli a itseng a manyane 'me e bobebe haholo ho feta li-skrini tsa tšepe tsa boholo bo lekanang, kahoo e fokotsa mojaro oa mochini oa skrine, e boloka tšebeliso ea matla le ho lelefatsa bophelo ba mochini oa skrine.
