Muindasitiri yezvivakwa zvekuvaka yanhasi, yakawanda uye yakawanda polyurethane inogona kuonekwa mumusika.Polyurethane chinhu chakasiyana-siyana, asi vanhu vazhinji havanzwisise kuti polyurethane chii kana kuti inoitei.Mukupindura mamiriro ezvinhu aya, mupepeti akaunganidza ruzivo rwunotevera kuti akupe iwe sainzi yakakurumbira.“

Chii chinonzi Polyurethane?

Zita rakazara re polyurethane inonzi polyurethane, inova izwi rinowanzoreva macromolecular compounds rine kudzokorora mapoka eurethane pacheni huru.Polyurethane iboka reurethane munyika yangu, uye rinogonawo kuva ne ether ester urea biuret urea boka rekutanga polyurethane sumo boka.Iyo inoumbwa ne polyaddition ye organic diisocyanate kana polyisocyanate uye dihydroxyl kana polyhydroxyl musanganiswa.Polyurethane zvinhu zvine zvakawanda zvekushandisa, zvinogona kutsiva rabha, purasitiki, naironi, nezvimwewo, inoshandiswa munhandare dzendege, mahotera, zvekuvakisa, mafekitari emotokari, migodhi yemarasha, mafekitari esimende, dzimba dzepamusoro-soro, villas, nzvimbo, matombo ane mavara. art, park etc.

Basa re polyurethane:

Polyurethane inogona kushandiswa mukugadzirwa kwepurasitiki, rabha, fiber, yakaoma uye inoshanduka foams, adhesives uye coatings, etc. Inogona kushandiswa munzvimbo dzakasiyana-siyana dzehupenyu hwevanhu uye ine zvakasiyana-siyana zvekushandisa.

1. Polyurethane furo: rakakamurwa kuita rigid polyurethane furo, semi-rigid polyurethane furo uye flexible polyurethane furo.Rigid polyurethane foam inonyanya kushandiswa pakuvaka zvigadziriso zvekupisa, zvigadziriso zvemafuta (thermal insulation yepombi zvivakwa, nezvimwewo), zvinodikanwa zvezuva nezuva (mibhedha, masofa, etc. mapedhi, mafiriji, air conditioners, nezvimwe., insulation layers, uye surfboards , etc. core material. ), uye nzira dzekufambisa (midziyo yakaita semacushion uye sirin'i dzemotokari, ndege, uye zvitima zvenjanji).

2. Polyurethane elastomer: Polyurethane elastomer ine zvakanakira simba rakanaka rekusimba, kubvarura simba, kukanganisa kupikisa, abrasion resistance, kusamira kwemamiriro ekunze, hydrolysis resistance, mafuta kuramba uye zvichingodaro.Inonyanya kushandiswa kupfekedza zvinhu (zvakadai sekudzivirira hose, washers, matai, rollers, giya, pombi, nezvimwewo), insulators, manyatera eshangu, uye matai akasimba.

3. Polyurethane isina mvura zvinhu: Polyurethane isina mvura zvinhu zviri nyore kushandisa.Inogona kusanganiswa uye kuputirwa panzvimbo uye kuporeswa neyakajairwa tembiricha uye hunyoro, uye dhizaini isina mvura isina seams, rubber elasticity uye kuita kwakanaka kunogona kuwanikwa.Uye nyore kugadzirisa mushure mekukuvara.Inowanzo shandiswa semidziyo yekugadzira, track uye yemunda track zvinhu, mijaho, mapaki epasi zvinhu, thermal insulation hwindo mafuremu, nezvimwe.

4. Polyurethane coating: Polyurethane coating ine adhesion yakasimba, uye firimu yekuvhara ine yakanakisa kupfeka kusagadzikana, kusagadzikana kwemvura uye kusagadzikana kwemakemikari.Inonyanya kushandiswa kupfekedza fenicha, machira ekuvaka uye mainduki ekudhinda maindasitiri.

5. Polyurethane adhesive: Kushanda kwechigadzirwa chakaporeswa kunogona kugadziriswa nekugadzirisa chiyero che isocyanate uye polyol, kuitira kuti igone kuwana kusungirirwa kwepamusoro kune substrate, kupikisa kwemvura kwakanakisisa, kupikisa kwemafuta uye kupikisa kwemakemikari.Polyurethane adhesives anonyanya kushandiswa mukurongedza, kuvaka, huni, mota, kugadzira shangu uye mamwe maindasitiri.

6. Zvinyorwa zveBiomedical: Polyurethane ine biocompatibility yakaisvonaka, saka zvishoma nezvishoma inoshandiswa zvakanyanya sezvinhu zvehupenyu.Inogona kushandiswa mukugadzira ekugadzira emwoyo pacemakers, artificial dialysis membranes, artificial esophagus, artificial dialysis membranes.

Iri pamusoro apa nderumwe ruzivo rwakakosha nezve chii chinonzi polyurethane zvinhu uye basa re polyurethane iro mupepeti akakugadzirira iwe.Polyurethane iri kuwana zvishoma nezvishoma kumira kwakasimba mumusika wezvivakwa zvekuvaka nekuda kwekuramba kwayo kwekutanga uye humwe hunhu.Netizens vanogona kutenga zvinoenderana nezvavanoda zvekuvandudza imba.
