Foam ya polyurethane ndi zinthu zomwe zimakhala ndi ma cell komanso mpweya wambiri, womwe umagwiritsidwa ntchito m'minda yambiri, kuphatikizapo kupanga matiresi.

Masiku ano kupanga polyurethane ndi njira yophatikizika yomwe imatipatsa zinthu zotetezeka, zapamwamba, komanso zosunga zachilengedwe.

Zowona Mwachidule…

Mu 1937 kwa nthawi yoyamba thovu la polyurethane linazindikirika mu labotale ndi Pulofesa Otto Bayer.Zinthu zatsopanozi zachita bwino kwambiri ndipo masiku ano zimagwiritsidwa ntchito m'magawo osiyanasiyana: mipando, nsapato, nyumba (chifukwa cha zotchingira zake) komanso m'makampani amagalimoto.

Chithovu cha polyurethane chimadziwika ndi kufewa kwapadera, kusungunuka, komanso kutsekemera kwambiri kwa mpweya ndi chinyezi;Pachifukwa ichi, imagwiritsidwa ntchito popanga matiresi ndi mapilo.

Kodi Foam ya Polyurethane Yapangidwa Bwanji?

Kuzindikira kumachitika mkati mwa ngalande yotsekedwa pomwe kupanikizika ndi vacuum zimasinthidwa mosalekeza kuti mupeze thovu.

Chifukwa cha kufalikira kwa madzi popanga, thovu la polyurethane ndilosavuta komanso lotha kubwezeretsedwanso.

Pamodzi mumphangayo ikuchitika polymerization anachita kuti amasintha thovu mu midadada yomalizidwa, ndiye kukonzedwa ndi kusema.

Makhalidwe 7 Ofunika Kwambiri pa Polyurethane Foam!

Ngati mukuganiza kugula matiresi a thovu, muyenera kudziwa 7 mikhalidwe yake:

1. Kuchulukana
2. Kunyamula mphamvu
3. Compressive mphamvu
4. Kupirira kutaya
5. Mtheradi kumangika mphamvu
6. Compress set
7. Kupirira

Chidziwitso:Zina mwazinthu / zithunzi zomwe zili m'nkhaniyi zikuchokera pa intaneti, ndipo gwero ladziwika.Amangogwiritsidwa ntchito kufotokoza mfundo kapena malingaliro omwe afotokozedwa m'nkhaniyi.Amangolankhulana ndi kuphunzira, ndipo sizinthu zina zamalonda.Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse nthawi yomweyo.
