Polyurethane Industry Research Report (Chikamu A)

1. Mhedziso yePururethane Industry

Polyurethane (PU) chinhu chakakosha chepolymer, chine huwandu hwakasiyana hwekushandisa uye akasiyana mafomu echigadzirwa anoita kuti ive chikamu chakakosha cheindasitiri yemazuva ano.Iyo yakasarudzika chimiro che polyurethane chinoipa chakanakisa chemuviri uye chemakemikari zvimiro, zvichiita kuti ishandiswe zvakanyanya munzvimbo dzakadai sekuvaka, mota, fenicha, uye shangu.Kuvandudzwa kweindasitiri yepolyurethane kunopesvedzerwa nezvinhu zvakasiyana sekuda kwemusika, hunyanzvi hwekuvandudza tekinoroji, uye mitemo yezvakatipoteredza, zvichiratidza kuchinjika kwakasimba uye kugona kwekusimudzira.

2. Mhedziso yePolyurethane Zvigadzirwa

(1) Polyurethane Foam (PU Foam)
Polyurethane furondechimwe chezvigadzirwa zvikuru zveindasitiri yepolyurethane, inogona kuiswa mufuro rakasimba uye furo rinochinjika zvinoenderana nezvinodiwa zvakasiyana zvekushandisa.Rigid furo rinowanzo shandiswa munzvimbo dzakaita senge kuvaka insulation uye inotonhora cheni yekufambisa mabhokisi, nepo furo rinochinjika richishandiswa zvakanyanya muzvigadzirwa zvakaita semamatiresi, masofa, uye zvigaro zvemotokari.Polyurethane furo rinotaridza zvakanakisa zvivakwa zvakaita sekureruka, kupisa kwemafuta, kunyura mutsindo, uye kumanikidza kuramba, kuita basa rakakosha muhupenyu hwazvino.

• Rigid PU Foam:Rigid polyurethane foam ifuro zvinhu zvine yakavharwa-sero chimiro, inoratidzwa nekunaka kwemaitiro kugadzikana uye kusimba kwemagetsi.Inowanzo shandiswa mumashandisirwo anoda kusimba kwepamusoro uye kuomarara, senge kuvharirwa kwekuvaka, mabhokisi ekufambisa anotonhora, uye matura efiriji.Iine huwandu hwayo hwepamusoro, yakaomesesa PU foam inopa yakanaka insulation kuita uye kumanikidza kuramba, zvichiita kuti ive chinhu chakanakira kuvaka insulation uye inotonhora ketani kurongedza.
• Flexible PU Foam:Flexible polyurethane foam ndeye furo zvinhu zvine yakavhurika-sero chimiro, inozivikanwa nekupfava uye elasticity.Inowanzoshandiswa mukugadzira matiresi, masofa, uye zvigaro zvemotokari, kupa nyaradzo nerutsigiro.Flexible PU foam inogona kugadzirwa kuita zvigadzirwa zvine density dzakasiyana uye kuomarara kusangana nekunyaradza uye kutsigirwa zvinodiwa zvezvigadzirwa zvakasiyana.Kupfava kwayo kwakanyanya uye kusimba kunoita kuti ive yakanakira kuzadza zvinhu zvefenicha uye zvemukati zvemotokari.
• Kuzvikanda-ganda PU Foam:Kuzvikanda-ganda polyurethane furo ifuro zvinhu zvinoumba chisimbiso chekuzvivhara pamusoro pemvura panguva yekupupa.Iine nzvimbo yakatsetseka uye yakakwirira kuoma kwepamusoro, inowanzoshandiswa mune zvigadzirwa zvinoda kutsetseka kwepamusoro uye kupfeka kusagadzikana.Kuzvicheka-ganda PU furo rinoshandiswa zvakanyanya mufenicha, zvigaro zvemotokari, midziyo yekusimba, uye mimwe minda, ichipa zvigadzirwa zvine chimiro chakanaka uye kusimba.

(2) Polyurethane Elastomer (PU Elastomer)
Polyurethane elastomer ine yakanakisa elasticity uye kupfeka kuramba, inowanzoshandiswa mukugadzira matai, zvisimbiso, vibration damping zvinhu, etc. Zvichienderana nezvinodiwa, polyurethane elastomers inogona kugadzirwa kuita zvigadzirwa zvine kuoma kwakasiyana uye elasticity siyana kusangana nezvinodiwa zvemaindasitiri akasiyana. uye zvigadzirwa zvevatengi.

(3)Polyurethane Adhesive (PU Adhesive)

Polyurethane adhesiveine unhu hwakanaka hwekubatanidza uye kudzivirira kwezvakatipoteredza, inoshandiswa zvakanyanya mukugadzira matanda, kugadzirwa kwemotokari, machira anonamira, etc. Polyurethane adhesive inogona kukurumidza kurapa pasi pekushisa kwakasiyana uye humidity mamiriro, kugadzira zvisungo zvakasimba uye zvakasimba, kuvandudza chigadzirwa chemhando uye kushanda.

3. Classification uye Applications of Polyurethane

ZvigadzirwaPolyurethane, seyakasiyana-siyana yepolymer zvinhu, ine hupamhi hwekushandisa munzvimbo dzakasiyana siyana, inonyanya kuiswa muzvikamu zvinotevera:
(1) Foam Products
Zvigadzirwa zvefuro zvinonyanya zvinosanganisira furo rakaomarara, furo rinochinjika, uye furo rekuzvikanda ganda, rine maapplication anosanganisira:

• Kuvaka Insulation: Furo rakasimba rinowanzo shandiswa mukuvaka zvivakwa zvekudzivirira senge ekunze madziro ekudzivirira mabhodhi uye denga rekuvhara mabhodhi, zvinobudirira kuvandudza simba resimba rezvivakwa.
• Kugadzira Fenicha: Furo rinochinjika rinowanzo shandiswa mukugadzira matiresi, masofa, macheya, kupa zvigaro zvekugara zvakanaka uye zviitiko zvekurara.Furo rekuzvicheka-ganda rinoshandiswa kushongedza fenicha yepamusoro, kuwedzera chigadzirwa aesthetics.
• Kugadzira Kwemotokari: Furo rinochinjika rinoshandiswa zvakanyanya muzvigaro zvemotokari, zvemukati zvemusuwo, zvichipa zviitiko zvekugara zvakanaka.Furo rekuzvicheka-ganda rinoshandiswa kune mota dzemukati mapaneru, mavhiri ekutungamirira, inosimudzira aesthetics uye kunyaradza.

(2) Elastomer Zvigadzirwa
Elastomer zvigadzirwa zvinonyanya kushandiswa munzvimbo dzinotevera:

• Kugadzira Kwemotokari: Polyurethane elastomers anoshandiswa zvakanyanya mukugadzira mota, senge matai, masisitimu ekumisikidza, zvisimbiso, zvinopa kunaka kunyura uye kuisa chisimbiso mhedzisiro, kuvandudza kugadzikana kwemotokari uye kunyaradza.
• Industrial Seals: Polyurethane elastomers anoshandiswa semidziyo yeakasiyana maindasitiri zvisimbiso, senge O-mhete, yekuisa chisimbiso gaskets, ine yakanakisa kupfeka kusamira uye corrosion kuramba, kuve nechokwadi chekushandisa chisimbiso kushanda.

(3) Adhesive Zvigadzirwa
Zvigadzirwa zvekunamira zvinonyanya kushandiswa munzvimbo dzinotevera:

• Woodworking: Polyurethane adhesives inowanzoshandiswa pakubatanidza nekubatanidza zvinhu zvehuni, zvine simba rakanaka rekubatanidza uye kudzivirira mvura, inoshandiswa zvakanyanya mukugadzira fenicha, matanda, nezvimwewo.
• Kugadzira Kwemotokari: Polyurethane adhesives anoshandiswa kubatanidza zvikamu zvakasiyana mukugadzira mota, senge mapaneru emuviri, zvisimbiso zvemahwindo, kuve nechokwadi chekugadzikana uye chisimbiso chezvikamu zvemotokari.
