Kodi kukana kuzizira kwa zida za polyurethane mu zida za thovu la polyurethane?

Pakati pa mitundu yonse ya zinthu za polyurethane,polyurethane high-pressure thovu makinathovu ndi gawo lofunikira.Mbali yaikulu ya zokutira za polyurethane ndizomwe zimakhala ndi porosity, choncho kachulukidwe kake ndi kakang'ono, mphamvu yeniyeni ndi yokwera, komanso imakhala ndi mawu otsekemera, kukana kugwedezeka, kutsekemera kwa magetsi, kukana kutentha., kukana kuzizira, kukana zosungunulira ndi makhalidwe ena.Mkonzi wotsatira adzakutengerani kuti mumvetsetse momwe kukana kuzizira kwa zinthu zopopera zopopera za zida zamakina a thovu la polyurethane kuli.

Nthawi zambiri, imakhala ndi makina abwino, olimba kwambiri, komanso magwiridwe antchito pamagawo onse.Ndi mtundu wa utoto wosiyanasiyana wokhala ndi chiyembekezo chachikulu chachitukuko.Njira zazikuluzikulu zogwiritsira ntchito ndi zokutira zamatabwa, zokutira zokonza magalimoto, zotetezera zowonongeka, zokutira pansi, zokutira zamagetsi, zokutira zapadera, etc. Choyipa ndi chakuti ntchito yomangayi ndi yovuta, malo omanga ndi ovuta kwambiri, ndipo filimu ya utoto ndi sachedwa kuwonongeka.

Zovala zamtundu umodzi wa polyurethane makamaka zimaphatikiza zokutira zamafuta a urethane, zokutira za polyurethane zochiritsa chinyezi, ndi zokutira zamakina otsekedwa a polyurethane thovu.Malo ogwiritsira ntchito sali otalikirapo ngati zokutira zamagulu awiri, zomwe zimagwiritsidwa ntchito kwambiri popaka pansi, zotetezera zowonongeka, zowonongeka zowonongeka, etc.Mitundu ya varnish ya utoto wa polyurethane imatchedwa polyurethane varnish.

Chithovu cha polyurethane chimagawidwa kukhala chithovu chofewa komanso chithovu cholimba.Ali ndi mapangidwe osiyanasiyana komanso ntchito zosiyanasiyana.Ntchito ya chithovu chofewa ndikumangirira, yomwe ingagwiritsidwe ntchito popanga sofa, ma cushions ndi zina zamkati zamagalimoto, pomwe ntchito ya thovu lolimba ndikutentha ndi madzi, ndipo nthawi zambiri amagwiritsidwa ntchito kuthandizira.Insulation ya matabwa omangira, makoma otchingira matenthedwe.Kugwiritsa ntchito thovu la polyurethane ndi lalikulu kwambiri, ndipo ndi chinthu chofunikira kwambiri m'mafakitale ambiri, ndipo zida zomwe zimagwiritsidwa ntchito pomaliza makina opangira thovu a polyurethane ndi makina opopera thovu amphamvu kwambiri, kotero kufunikira kwa kugwiritsa ntchito thovu la polyurethane kumapita. popanda kunena.

Kukonzekera kwathunthu kwa zida kumaganizira mozama za kugwiritsidwa ntchito kwa malo.Ngakhale mutakhala ndi magulu angapo amagulu a mapaipi otenthetsera matenthedwe, malo osunthika opangidwira amatha kukhala otsimikizika, ndipo wogwiritsa ntchito m'modzi akhoza kukankha ndi kukoka zida.Kukwaniritsidwa kwa ntchito yayikulu yonyamula zida za gulu la zida zotchinjiriza chitoliro kumawonjezera kugwiritsidwa ntchito kwa zida za thovu la polyurethane, zomwe zimathandizira kwambiri woyendetsa, zomwe sizimangopulumutsa anthu ogwira ntchito komanso kumapangitsa kuti ntchitoyo ikhale yabwino.
