Monga polyurethane okhwima thovu (PU okhwima thovu) ali ndi makhalidwe a kulemera kuwala, zabwino matenthedwe kutchinjiriza kwenikweni, kumanga yabwino, etc., komanso ali ndi makhalidwe abwino monga kutchinjiriza phokoso, kukana mantha, kutchinjiriza magetsi, kukana kutentha, kuzizira, zosungunulira kukana, etc., wakhala ankagwiritsa ntchito kunyumba ndi kunja.Muzamlengalenga, kupanga zombo, mafuta, zida zamagetsi, magalimoto, chakudya ndi magawo ena ogulitsa.

Ntchito zazikulu za thovu lolimba la PU ndi izi:

1. Zipangizo za refrigeration za zida zapakhomo ndi mafakitale ogulitsa chakudya

Firijis ndi mafiriji omwe amagwiritsa ntchito thovu lolimba la PU popeza wosanjikiza wotsekera amakhala ndi wosanjikiza woonda kwambiri.Pansi pa miyeso yakunja yofanana, voliyumu yogwira ntchito imakhala yayikulu kwambiri kuposa momwe zida zina zimagwiritsidwira ntchito ngati zosanjikiza, ndipo kulemera kwa chipangizocho kumachepetsedwanso.

Zotenthetsera madzi am'nyumba, zotenthetsera madzi a solar, ndi zolumikizira mowa nthawi zambiri zimagwiritsa ntchito zida zolimba za polyurethane thovu.Chithovu cholimba cha PU chimagwiritsidwanso ntchito popanga zopangira zonyamula zonyamula katundu, mankhwala ndi zakudya zomwe zimafunikira kutchinjiriza ndikutetezedwa.

2.Zida zamafakitale ndipayipikutsekereza

Matanki osungira ndimapaipindi zida zomwe zimagwiritsidwa ntchito kwambiri popanga mafakitale, ndipo zimagwiritsidwa ntchito kwambiri mumafuta, gasi, kuyenga mafuta, makampani opanga mankhwala, mafakitale opepuka ndi mafakitale ena.Mawonekedwe a thanki yosungiramo ndi yozungulira kapena yozungulira, ndipo thovu lolimba la PU limatha kupangidwa ndi kupopera mbewu mankhwalawa, kuthira ndi kumata thovu lopangidwa kale.Monga apayipimatenthedwe kutchinjiriza zakuthupi, chimagwiritsidwa ntchito kwambiri kutchinjiriza matenthedwe mapaipi mu mayendedwe mafuta opandamapaipindi mafakitale a petrochemical, ndipo asintha bwino zida ndi mayamwidwe apamwamba amadzi monga perlite.

3. Zida zomangira

Kumanga nyumba ndi imodzi mwamagawo ofunikira kwambiri a thovu lolimba la PU.Ku China, thovu lolimba lakhala likudziwika chifukwa cha kutchinjiriza kwamafuta komanso kutsekereza madzi padenga la nyumba zogona ndi maofesi,kumanga Insulationmzakuthupi, ndi zipangizo zotetezera kutentha kwachipinda chozizira, malo osungiramo tirigu, etc. The sprayed hard thovu amagwiritsidwa ntchito padenga, ndipo wosanjikiza wotetezera amawonjezeredwa, omwe ali ndi zotsatira ziwiri za kutsekemera kwa kutentha ndi madzi.

Wolimba polyurethanemapepala a sandwichamagwiritsidwa ntchito kwambiri m'mafakitale, nyumba zosungiramo katundu, mabwalo amasewera, nyumba zogona anthu, nyumba zogona, nyumba zopangira komanso kuphatikizachipinda chozizira, monga mapanelo a padenga ndi makoma a khoma.Chifukwa cha kulemera kwake, kutsekemera kwa kutentha, madzi, zokongoletsera ndi zina, komanso mayendedwe abwino (kukhazikitsa), kupititsa patsogolo ntchito yomangamanga, ndi yotchuka kwambiri pakati pa okonza, omanga ndi omanga.

4.Zida zotsanzira matabwa 

High-kachulukidwe (kachulukidwe 300 ~ 700kg/m3) PU olimba thovu kapena galasi CHIKWANGWANI analimbitsa olimba thovu ndi structural thovu pulasitiki, amadziwikanso kutimatabwa a polywood.Itha kulowa m'malo mwa nkhuni monga mbiri yakale, matabwa, zinthu zamasewera, zokongoletsa,kunyumbamipando,mafelemu agalasi,trowel, bedi headboard ,prosthesis,upholstery,zida zowunikira, ndikutsanzira matabwa kusema luso, etc., ndi maonekedwe ndi mtundu wa mankhwala akhoza kusinthidwa malinga ndi zosowa, amene ali ndi msika wotakata prospect.The structural chithovu okhwima opangidwa ndi kuwonjezera lawi retardant ali apamwamba kwambiri lawi retardancy kuposa nkhuni.

5.Chokongoletsera cornice

Kujambula koronandipo mizere ya pulasitala ndi mizere yokongoletsera mkati, koma zida zopangira ndi zomangamanga ndizosiyana.Mizere ya PU imapangidwa ndi PU zopangira zopangira.Amapangidwa ndi thovu la polymer, ndipo amapangidwa ndi thovu lolimba la pu.Chithovu cholimba cha pu ichi chimasakanizidwa ndi zigawo ziwiri pa liwiro lalikulu mu makina otsekemera, kenako ndikulowa mu nkhungu kupanga ndikupanga.Epidermis yolimba.Zopanda poizoni komanso zopanda vuto, zokonda zachilengedwe.

Zokongoletsera za koronasizili zopunduka, zosweka, kapena zowola;kukana dzimbiri, asidi ndi alkali kukana, ndipo amatha kusunga bata la zinthu chaka chonse.Osadyedwa ndi njenjete, palibe chiswe;palibe mayamwidwe amadzi, palibe seepage, chitha kutsukidwa mwachindunji.Kutentha kwapamwamba kwambiri, ndi chinthu chabwino kwambiri chotetezera kutentha, sichidzatulutsa milatho yozizira ndi kutentha.

6.Mannequins

Zovalamannequinsndi gawo latsopano logwiritsa ntchito m'makampani a polyurethane.Zitsanzondi chimodzi mwa zinthu zofunika kwambiri mu sitolo ya zovala.Amatha kuvala sitolo ndikuwonetsa zofunikira za zovala.Zovala zomwe zilipo pamsika ndizopangidwa ndi fiberglass fiber, pulasitiki ndi zida zina.Ulusi wa Fiberglass umakhala wosasunthika bwino, umakhala wofewa pang'ono, ndipo ulibe kutha.Pulasitiki ali ndi zolakwika monga kufooka mphamvu ndi moyo waufupi.Mtundu wa chovala cha polyurethane uli ndi ubwino wa kukana kuvala bwino, mphamvu zabwino, kusungunuka, kuyendetsa bwino, komanso kuyerekezera kwakukulu.

7.Other ntchito wamba

Kuphatikiza pazomwe tafotokozazi, thovu lolimba la polyurethane lingagwiritsidwenso ntchito podzaza zitseko ndi kupanga mipira yoyandama ya nsomba, etc.
Khomo lodzaza thovu la polyurethane limawoneka ngati khomo lina lililonse, komabe, mawonekedwe amkati ndi osiyana kwambiri.Nthawi zambiri chitseko chopanda utoto chimakhala chopanda mkati, kapena chodzaza ndi pepala la uchi, pomwe chitseko chodzaza thovu cholimba cha polyurethane sichingokhala chobiriwira komanso chokonda zachilengedwe, komanso chimalimbitsa kulimba kwa chitseko, ndikupangitsa chitseko kukhala cholimba komanso champhamvu. , kaya ndi katundu wolemetsa, thovu la madzi, Kaya itenthedwa pamoto, ikhoza kuonetsetsa kuti sichidzapunduka.Tekinoloje iyi imachotsa zitseko zophatikizika, zitseko zamatabwa zimakhala ndi zovuta monga mapindikidwe ndi chinyezi.
