I aso nei o mea faufale pisinisi, sili atu ma sili atu polyurethane e mafai ona vaaia i le maketi.O le polyurethane o se mea e sili ona lelei, ae o le toʻatele o tagata e le malamalama poʻo le a le polyurethane poʻo le a le mea e fai.I le tali atu i lenei tulaga, ua tuufaatasia e le faatonu faamatalaga nei e avatu ai ia te oe le faasaienisi lauiloa.“

O le a le Polyurethane?

O le igoa atoa o le polyurethane o le polyurethane, o se faaupuga lautele mo macromolecular compounds o loʻo i ai le toe faia o vaega urethane i luga o le filifili autu.O le Polyurethane o se vaega laiti ole urethane i lo'u atunuu, ma e mafai foi ona iai le eter ester urea biuret urea group first polyurethane ntroduction group.E faia i le polyaddition o organic diisocyanate poʻo le polyisocyanate ma le dihydroxyl poʻo le polyhydroxyl compound.Polyurethane mea e iai le tele o faʻaoga, e mafai ona suitulaga i le paʻu, palasitika, nylon, ma isi, faʻaaogaina i malae vaʻalele, faletalimalo, mea fau fale, fale gaosi taavale, koale, fale sima, fale mautotogi maualuga, villas, faʻafanua, maa lanu. faatufugaga, paka ma isi.

Ole matafaioi ole polyurethane:

E mafai ona faʻaaogaina le Polyurethane i le gaosiga o palasitika, paʻu, alava, faʻamaʻa ma faʻafefeteina foam, faʻapipiʻi ma faʻapipiʻi, ma isi.

.O le foam polyurethane malosi e masani ona faʻaaogaina mo le fausiaina o mea faʻapipiʻi vevela, mea faʻamalama faʻamalama (faʻavela vevela o fale paipa, ma isi mea), mea e manaʻomia i aso uma (moega, sofas, ma isi pads, pusaaisa, ea malulu, ma isi, faʻamau faʻapipiʻi, ma laupapa faaseʻe. , ma isi mea autu. ), ma auala o felauaiga (mea e pei o aluga ma fa'alo mo taavale, vaalele, ma taavale afi).

2. Polyurethane elastomer: O le polyurethane elastomer o loʻo i ai le lelei o le malosi faʻamalosi lelei, malosi o loimata, faʻalavelave aʻafiaga, faʻalavelave faʻafefe, faʻafefe o le tau, faʻafefeteina o le hydrolysis, faʻamaʻi suauu ma isi.E masani ona faʻaaogaina mo mea faʻapipiʻi (pei o le puipuiga o faʻauʻu, fufulu, paʻu, rollers, gears, paipa, ma isi), insulators, seevae seevae, ma paʻu malo.

3. Polyurethane mea e le susu: Polyurethane mea e le susu e matua faigofie lava ona faʻaoga.E mafai ona faʻafefiloi ma faʻapipiʻi i luga o le saite ma faʻamalolo i le vevela masani ma le susu, ma e mafai ona maua se mea e le susu e aunoa ma se suʻiga, elasticity paʻu ma faʻatinoga lelei.Ma faigofie ona toe faaleleia pe a uma ona faaleagaina.E masani ona faʻaaogaina e pei o mea faʻapipiʻi, auala ma fanua auala mea, taʻavale, mea faʻavae paka, faʻamalama faʻamalama faʻamalama, ma isi.

4. Polyurethane coating: Polyurethane coating o loʻo i ai le faʻapipiʻi malosi, ma o le ata faʻapipiʻi e sili ona lelei le ofuina o le ofuina, vai faʻafefe ma vailaʻau.E masani ona faʻaaogaina mo meaafale faʻapipiʻi, faʻapipiʻi mea faufale ma inks lomitusi fale gaosimea.

5. Faʻapipiʻi Polyurethane: O le faʻatinoga o le oloa faʻamalolo e mafai ona fetuʻunaʻi e ala i le fetuunaʻi o le fua o le isocyanate ma le polyol, ina ia mafai ai ona ausia le maualuga o le pipii i le substrate, faʻafefeteina lelei o le vai, suauʻu suauʻu ma vailaʻau.Polyurethane adhesives e masani ona faʻaaogaina i le afifiina, fausiaina, laupapa, taavale, seevae ma isi pisinisi.

6. Biomedical material: Polyurethane e sili ona lelei le biocompatibility, o lea e faasolosolo malie ona faʻaaogaina e avea ma mea faʻapitoa.E mafai ona faʻaaogaina i le gaosiga o fatu fatu fatu, vaʻa toto faʻapitoa, ponaivi faʻapitoa, esophagus faʻapitoa, fatugaʻo faʻapitoa, membranes dialysis faʻapitoa, ma isi.

O loʻo i luga o nisi faʻamatalaga talafeagai e uiga i mea o le polyurethane ma le matafaioi o le polyurethane na tuʻufaʻatasia e le faatonu mo oe.O le Polyurethane o loʻo faasolosolo malie ona maua se tulaga mautu i le maketi o mea fau fale ona o lona teteʻe ma isi uiga.E mafai e Netizens ona faʻatau e tusa ai ma o latou lava manaʻoga faʻaleleia fale.
