Ibifunga bya Polyurethane vs. Silicone: Ni ikihe gikwiye kuri wewe?

Guhitamo agakoresho gafunga neza ni kimwe mu byemezo by'ingenzi bigira ingaruka ku mikorere y'igihe kirekire y'imishinga y'ubwubatsi, iy'inganda, n'iy'ubuhanga mu by'ubugeni. Agakoresho gafunga bigira ingaruka ku buryo butaziguye:

  • --Gukomera kw'ingingo

  • --Gufata amazi n'umwuka mu buryo bufunze

  • --Umutekano mu miterere

  • --Ubwiza bw'ubwiza

  • --Ingendo zo kubungabunga

  • --Ikiguzi cy'ubuzima

Nk'inganda mpuzamahanga yibanda kuibifunga bya silikoni, ibifunga bya polyurethane (PU), Sisitemu zo gufatanya za PU, naibisubizo byo kwirinda amazi mu bwubatsi, Siwayitanga shimi kandi isobanukiwe imbaraga n'inzitizi zayo uhereye kurisiyansi y'ibikoresho, ubwubatsi, nabishingiye kuri porogaramuicyerekezo.

Iyi nyandiko itanga uburyoigereranya ryuzuye kandi ryemewe cyaneya PU ugereranije na silikoni—ishyigikiwe naUburyo bwo gusuzuma ASTM/ISO, amahame y'ibizamini bya laboratwari, naubumenyi ku bijyanye n'ikoreshwa ry'ibintu nyabyouhereye ku musaruro wa Siway n'uburambe bw'abakiriya.

1. Ubutabire bw'ibikoresho n'imyitwarire y'imiterere

1.1 Ibifunga bya Polyurethane (Ubutabire bwa Polymer Organic)

Ibifunga bya polyurethane (PU) bishingiye ku buryo polyols na isocyanate bikora, bigatuma habahoelastomeri y'umwimerere ifitanye isano rya cross-linkedIyi miterere itanga ibikoresho byo gufunga PU:

Ibifunga bya Polyurethane (Ubutabire bwa Polymer Organic)

  • --Ubudahangarwa bwinshi bw'amarira

  • --Gufatana cyane n'ibice bifite imyenge

  • --Ubudahangarwa buhanitse bwo kwangirika

  • --Imikorere myiza cyane ya mekanike

Ibifunga bya PU bikora imigozi iramba ya elastomeric ibereye:

  • --Ingingo za beto

  • --Ingingo zo kwimuka kw'inyubako

  • --Iteraniro ry'inganda

  • --Pasi iremereye cyane

  • --Gufunga uruziga hakoreshejwe imbaraga za mekanike

Urufatiro rwazo rw’umwimerere rutuma zishobora kwangirika n’imiraba y’urumuri rw’izuba mu gihe kirekire keretse iyo zihinduwe by’umwihariko—ni yo mpamvu ibikoresho bya PU byo mu rwego rw’umwuga bisabaIbikoresho bitera imbaraga imirasire ya UV, antioxydants, naguhuza irangi ririnda.

1.2 Ibifunga bya silikoni (Ubutabire bwa polimeri budafite umwimerere)

Ibifunga bya silikoni bishingiye kuiminyururu ya polysiloxane (Si–O–Si), umugongo udashingiye ku binyabuzima utanga ikintu kidasanzwe:

Ibifunga bya silikoni (Ubutabire bwa polimeri budafite umwimerere)

  • --Uburimbane bw'imiraba y'urumuri

  • --Ubushyuhe buhamye
