1. Chidule cha Makampani a Polyurethane

Polyurethane (PU) ndichinthu chofunikira kwambiri cha polima, chomwe ntchito zake zosiyanasiyana ndi mitundu yosiyanasiyana yazogulitsa zimapangitsa kuti ikhale gawo lofunika kwambiri pamakampani amakono.Kapangidwe kake ka polyurethane kumapangitsa kuti ikhale yabwino kwambiri komanso yamankhwala, ndikupangitsa kuti igwiritsidwe ntchito kwambiri m'malo monga zomangamanga, magalimoto, mipando, nsapato.Kukula kwamakampani a polyurethane kumakhudzidwa ndi zinthu zosiyanasiyana monga kufunikira kwa msika, luso laukadaulo, ndi malamulo a chilengedwe, kuwonetsa kusinthika kwamphamvu komanso kuthekera kwachitukuko.

2. Mwachidule za Polyurethane Products

(1) Polyurethane Foam (PU Foam)
Polyurethane thovundi chimodzi mwazinthu zazikulu zamakampani a polyurethane, omwe amatha kugawidwa kukhala thovu lolimba komanso thovu losinthika molingana ndi zosowa zosiyanasiyana.Chithovu cholimba chimagwiritsidwa ntchito kwambiri m'malo monga zotsekera zomanga ndi mabokosi ozizirira, pomwe thovu losinthika limagwiritsidwa ntchito kwambiri pazinthu monga matiresi, sofa, ndi mipando yamagalimoto.Foam ya polyurethane imawonetsa zinthu zabwino kwambiri monga zopepuka, zotsekemera zotenthetsera, kuyamwa kwa mawu, komanso kukana kukanikiza, zomwe zimakhudza kwambiri moyo wamakono.

• Chithovu cha PU cholimba:Chithovu cholimba cha polyurethane ndi thovu lopangidwa ndi ma cell otsekedwa, omwe amadziwika ndi kukhazikika kwamapangidwe komanso mphamvu zamakina.Amagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira mphamvu zambiri komanso kulimba mtima, monga kutsekereza nyumba, mabokosi oyendera mayendedwe ozizira, ndi malo osungiramo firiji.Ndi kachulukidwe kake, thovu lolimba la PU limapereka ntchito yabwino yotchinjiriza komanso kukana kukanikiza, ndikupangitsa kuti ikhale chinthu chabwino chomangira kutchinjiriza ndi kuyika kwa unyolo wozizira.
• Flexible PU Foam:Flexible polyurethane foam ndi chithovu chokhala ndi mawonekedwe otseguka, odziwika chifukwa cha kufewa kwake komanso kukhazikika.Amagwiritsidwa ntchito kwambiri popanga matiresi, sofa, ndi mipando yamagalimoto, kupereka chitonthozo ndi chithandizo.Flexible PU thovu imatha kupangidwa kukhala zinthu zokhala ndi makulidwe osiyanasiyana komanso kuuma kuti zikwaniritse chitonthozo ndi chithandizo chazinthu zosiyanasiyana.Kufewa kwake komanso kulimba mtima kwake kumapangitsa kukhala chinthu choyenera kudzaza mipando ndi zamkati zamagalimoto.
• Phulusa lodzitchinjiriza la PU:Foam yodzitchinjiriza yokhala ndi khungu la polyurethane ndi thovu lomwe limapanga chisindikizo chodzitchinjiriza pamtunda pakupanga thovu.Ili ndi mawonekedwe osalala komanso olimba kwambiri, omwe amagwiritsidwa ntchito kwambiri pazinthu zomwe zimafuna kusalala kwapamwamba komanso kukana kuvala.Foam yodzitchinjiriza ya PU imagwiritsidwa ntchito kwambiri pamipando, mipando yamagalimoto, zida zolimbitsa thupi, ndi magawo ena, kupereka zinthu zowoneka bwino komanso zolimba.

(2) Polyurethane Elastomer (PU Elastomer)
Polyurethane elastomer ali elasticity kwambiri ndi kuvala kukana, amene amagwiritsidwa ntchito popanga matayala, zisindikizo, kugwedera damping zipangizo, etc. Malinga ndi zofunika, polyurethane elastomers akhoza kupangidwa mu mankhwala ndi kuuma osiyanasiyana ndi elasticity ranges kukwaniritsa zofunika zosiyanasiyana mafakitale. ndi zinthu za ogula.

(3)Zomatira za Polyurethane (PU Adhesive)

Polyurethane zomatiraali ndi zinthu zabwino kwambiri zomangira komanso kukana zachilengedwe, zomwe zimagwiritsidwa ntchito kwambiri popanga matabwa, kupanga magalimoto, zomatira za nsalu, etc. Zomatira za polyurethane zimatha kuchiza mwachangu pazikhalidwe zosiyanasiyana za kutentha ndi chinyezi, kupanga zomangira zolimba komanso zolimba, kuwongolera mtundu wazinthu ndi magwiridwe antchito.

3. Gulu ndi Ntchito za Polyurethane

ProductsPolyurethane, monga zinthu zosunthika polima, imakhala ndi ntchito zosiyanasiyana m'magawo osiyanasiyana, makamaka m'magulu otsatirawa:
(1) Zogulitsa Chithovu
Zopangira thovu makamaka zimakhala ndi thovu lolimba, thovu losinthika, komanso thovu lodzipukuta lokha, lomwe limaphatikizapo:

• Kumanga Insulation: Chithovu cholimba chimagwiritsidwa ntchito nthawi zambiri popanga zida zomangira monga ma board akunja otchingira khoma ndi ma board otchinjiriza padenga, kupititsa patsogolo mphamvu zamagetsi mnyumba.
• Kupanga Mipando: Chithovu chosinthika chimagwiritsidwa ntchito kwambiri popanga matiresi, sofa, mipando, kupereka mipando yabwino komanso kugona.Chithovu chodzitchinjiriza chimagwiritsidwa ntchito kukongoletsa mipando pamwamba, kukulitsa kukongola kwazinthu.
• Kupanga Magalimoto: Chithovu chosinthika chimagwiritsidwa ntchito kwambiri pamipando yamagalimoto, mkati mwa zitseko, kupereka zokumana nazo zomasuka.Chithovu chodzitchinjiriza chimagwiritsidwa ntchito ngati mapanelo amkati agalimoto, mawilo owongolera, kupititsa patsogolo kukongola komanso chitonthozo.

(2) Zogulitsa za Elastomer
Zogulitsa za Elastomer zimagwiritsidwa ntchito kwambiri m'malo otsatirawa:

• Kupanga Magalimoto: Ma polyurethane elastomers amagwiritsidwa ntchito kwambiri popanga magalimoto, monga matayala, makina oyimitsidwa, zisindikizo, kupereka mayamwidwe abwino komanso kusindikiza, kukonza bata ndi chitonthozo chagalimoto.
• Zisindikizo Zamakampani: Ma polyurethane elastomers amagwiritsidwa ntchito ngati zida zosindikizira zosiyanasiyana zamafakitale, monga mphete za O, ma gaskets osindikiza, okhala ndi kukana kwamphamvu kwambiri komanso kukana dzimbiri, kuwonetsetsa kuti zida zosindikiza zimagwira ntchito.

(3) Zomatira Zopangira
Zomatira zimagwiritsidwa ntchito kwambiri m'malo otsatirawa:

• Kupanga matabwa: Zomatira za polyurethane zimagwiritsidwa ntchito polumikizira ndikulumikiza zida zamatabwa, zokhala ndi mphamvu zomangirira bwino komanso kukana madzi, zomwe zimagwiritsidwa ntchito kwambiri popanga mipando, matabwa, ndi zina zambiri.
• Kupanga Magalimoto: Zomatira za polyurethane zimagwiritsidwa ntchito polumikizira magawo osiyanasiyana popanga magalimoto, monga mapanelo amthupi, zisindikizo zamawindo, kuwonetsetsa kukhazikika ndi kusindikiza zigawo zamagalimoto.
