Kuramba kweTPU nehydrolysiszvinoreva kugona kwayo kuramba "kurwiswa" nehunyoro uye kudzivirira kuora kwekushanda kwayo. Kugona uku kunotsanangurwa nechimiro chemakemikari uye zvinowedzerwa zveTPU, uye chiratidzo chikuru chekuongorora kuvimbika kwayo kwenguva refu munzvimbo dzine hunyoro kana dziri pasi pemvura.
Chinhu Chinokosha: Yakavakirwa paPolyester vs.TPU yakavakirwa paPolyether
Musiyano mukuru mukuramba hydrolysis unobva pachimiro che "chikamu chakapfava" chiri mukati meketani yemamorekuru.
- TPU yakavakirwa papolyester: Mabhondi eester ari mucheni yemamorekuru anogona kukanganiswa nehydrolysis, zvichikonzera kudzikira kukuru kwekushanda munzvimbo dzinopisa uye dzine hunyoro. Nokudaro, ine simba shoma rekudzivirira hydrolysis.
- TPU yakavakirwa paPolyether: Zvisungo zve ether mucheni yemamorekuru zvakagadzikana uye zvinoramba hydrolysis, zvichipa kuramba hydrolysis kwakanaka. Izvi zvinoita kuti ive sarudzo inosarudzwa yekushandisa mumvura kana mumhepo ine hunyoro hwakawanda.
Muchidimbu: Pakushandisa kunoda kubata mvura kwenguva refu kana nzvimbo dzine hunyoro, TPU yakagadzirwa nepolyether inofanira kukosheswa.
Zviratidzo zveKuongorora Kwakakosha
Kuramba kwehydrolysis kunowanzo ongororwa kuburikidza nemiedzo yekukwegura nekukurumidza, ichitarisa pane zvinotevera zvakakosha:
- Kuchengetedza Simba reKubata: Chikamu chesimba rekubata rinochengetwa mushure mekukwegura zvichienzaniswa nehukuru hwepakutanga. Kuchengetedza kwakanyanya kunoratidza kuti simba rekudzivirira hydrolysis riri nani; indasitiri inowanzoda ≥80%.
- Kuchinja kweKureba kweChinhu Pakuzorora: Kunoyera kuchinja kwekuchinjika kwezvinhu. Kuchinja kudiki kunoratidza kushanda kwakasimba.
- Kuchinja muKuoma: Kunoratidza kuchinja kwekuoma kwechinhu pamusoro. Kuchinja kudiki kunoratidza kugadzikana kuri nani kwechinhu chikuru.
- Chitarisiko Chemufananidzo: Tarisa kana pamusoro pemuenzaniso paine zviratidzo zvekuora zvakaita sekutsemuka, kusviba, kana kuti kutsemuka.
Nzira dzeKuyedza uye Maitiro
Kusakwanisa kushandisa hydrolysis kunoongororwa kuburikidza nemiedzo yekukwegura nekukurumidza. Mitemo mikuru inosanganisira:
- ISO 4611: Mwero wepasi rose wekuchengetedza kuchembera kwemapurasitiki.
- ASTM D570: Nzira yakajairika yekuyedza yekunyudza mvura mumapurasitiki.
- DIN 53366: Inoshandiswa mukuisa muzvikamu kugadzikana kwehydrolysis yezvinhu.
Mamiriro ekuyedza akajairika 70°C / 95% Relative Humidity (RH) kwemaawa mazana kusvika zviuru, nekutora sampuro nguva nenguva yekutarisa shanduko dzekushanda.
Nzira Dzekuvandudza Kuramba Kusashanda Kwemvura
Kana kuramba kwehydrolysis kweTPU yakavakirwa papolyester kusina kukwana, nzira dzinotevera dzinogona kushandiswa:
- Wedzera Zvinosimbisa Kushanda Kwemahydrolysis: Imwe yenzira dzinoshanda zvikuru ndeyekuwedzera polycarbodiimide (PCD) kana zvimwe zvinorwisa hydrolysis. Izvi zvinogadzirisa mamorekuru akatyoka uye zvinononotsa kuora.
- Gadzirisa Maumbirwo eMorekuru: Kusarudza polyester polyols dzine huremu hwakanyanya hwemamorekuru, cheni refu, kana zvivakwa zvine matavi zvinogonawo kuvandudza kugadzikana kwehydrolysis kusvika pamwero wakati.
Pfupiso uye Mazano Ekusarudza
- Sarudzo Yakakosha: Munzvimbo dzine hunyoro, isa TPU yakavakirwa papolyether pakutanga.
- Hwaro Hwekuongorora: Ongorora huwandu hweTPU magiredhi akasiyana nekuenzanisa mwero wekuchengetedza simba rekusimba uye rumwe ruzivo kubva mukuongororwa kwekukwegura.
- Kuenzana Kwakakosha: Ziva kuti TPU yakavakirwa papolyether inogona kunge iine simba remuchina rakaderera uye inodzivirira kupisa zvishoma zvichienzaniswa nepolyester. Kuenzana pakati pekudzivirira hydrolysis uye hunhu hwemuchina kunofanirwa kuwanikwa.
Kunzwisisa ma parameter aya kuchakubatsira kusarudza TPU yakakodzera chigadzirwa chako, zvichiita kuti chive chakavimbika kwenguva refu munzvimbo yacho.
NezveduYantai Linghua New Material Co., Ltd.
Yantai Linghua New Material Co., Ltd. ine hunyanzvi hwakasimba hwekutsvaga nekugadzira zvinhu uye kugona kugadzira zvinhu zvakagadzirwa neTPU yakagadzirwa nepolyether. Semutengesi weTPU ane hunyanzvi, yakavambwa muna 2010, kambani iyi yakakura kuita kambani yakazara inobatanidza kutengeserana kwezvinhu zvakagadzirwa, tsvakurudzo nekuvandudzwa kwezvinhu, uye kugadzirwa nekutengesa.
Zvigadzirwa zvayo zveTPU zvakagadzirwa nepolyether, zvichibva pachimiro che ether bond mu molecular chain, zvinopa zvinhu izvi simba rakanaka re hydrolysis, kushanda zvakanaka pakupisa kwakaderera (kusvika -40°C uye pasi), uye kuramba zvakanyanya kubatwa nehuswa. Pamusoro pezvo, zvigadzirwa izvi zvine simba guru remuchina, kuramba kukwesha zvakanaka, uye kugona kushandiswa zvakanaka, uku zvichitevedzera zvinodiwa zvepasi rose zvinosanganisira REACH, RoHS, uye FDA. Zvichishandisa hunhu uhwu, zvigadzirwa zve polyether TPU zveLinghua New Materials zvinoshandiswa zvakanyanya muwaya netambo, zvikamu zvemotokari, mapombi emoto, machubhu nemapombi, uye shangu - mashandisirwo emaindasitiri nevatengi anoda kuramba kwakanyanya kwemamiriro ekunze uye kugadzikana kwenguva refu.
