Chithovu cha polyurethane chiyenera kukhala cholimba kapena kusinthasintha malinga ndi momwe ntchito zake zingakhalire.Kusinthasintha kwa nkhaniyi kumapangitsa kuti zigwirizane ndi zosowa za mafakitale m'magulu onse ndikukhalapo m'moyo watsiku ndi tsiku kuti zitonthozedwe ndi chitetezo.
1, Zinthu zolimba komanso zosinthika za thovu la polyurethane
Izi zamphamvu kwambiri zotsekereza zimachokera ku kusakaniza kwa zigawo ziwiri, polyol ndi isocyanate, mumadzimadzi.Akachitapo kanthu, amatulutsa thovu lolimba la PU, lokhala ndi mawonekedwe olimba komanso osamva.Kutentha kwaiye ndi anachita angagwiritsidwe ntchito vaporize wothandizila kutupa, kotero zinthu chifukwa ali ndi voliyumu lalikulu kwambiri kuposa mankhwala oyambirira.
Chithovu cholimba chingagwiritsidwe ntchito popopera mu situ kapena mu situ poponya.Polyurethane wopopera ndi jekeseni wa polyurethane ndi mitundu ya polyurethane yomwe imagwiritsidwa ntchito pomanga ndi mafakitale m'njira zosiyanasiyana.
Flexible polyurethane thovu ndi zotanuka ma cell otseguka.Iwo amawonekera chifukwa cha mphamvu zawo zochepetsera komanso kusinthasintha, chifukwa malingana ndi zowonjezera zomwe zimawonjezeredwa ndi njira zopangira zomwe zimagwiritsidwa ntchito, machitidwe osiyanasiyana amatha kutheka.

2, Ndi thovu liti lomwe mungasankhe pakugwiritsa ntchito kulikonse?
Kusankhidwa kwa polyurethane yoyenera kwambiri pa cholinga chilichonse ndikofunikira kuti mupeze zotsatira zofunikira.Chifukwa chake, thovu lolimba la polyurethane lomwe limapopedwa ndiye insulator yabwino kwambiri.Ma thovu osinthika ndi oyenera kuumba.
Chithovu cholimba chimapangitsa kuti pakhale kutentha kwambiri komanso kutsekemera kwamayimbidwe ndi makulidwe ochepa.Chithovu cholimba cha polyurethane chimaperekedwa m'mapepala, midadada ndi zidutswa zoumbidwa, zomwe zimasintha malinga ndi zomwe kasitomala akufuna pa mawonekedwe, mawonekedwe, mtundu, ndi zina. Itha kugwiritsidwa ntchito popaka utoto.

Kumbali inayi, thovu losinthika chifukwa cha chitonthozo chake ndi kulimba kwake ndi lothandiza pamipando (sofa, matiresi, mipando ya cinema) kuti ikhale hypoallergenic ndikupereka zomaliza zingapo ndi mapangidwe.

Chidziwitso:Nkhaniyi idatengedwa kuchokera ku blog.synthesia.com/.Pokhapokha kuyankhulana ndi kuphunzira, osachita zina zamalonda, sikuyimira maganizo ndi malingaliro a kampani, ngati mukufuna kusindikizanso, chonde funsani wolembayo woyambirira, ngati pali kuphwanya, chonde tilankhule nafe nthawi yomweyo kuti tichotse processing.
