PPDI yakachena 1,4-Phenylene diisocyanate (PPDI), nhamba yeCAS ndeye 104-49-4. PPDI ndeyepamberi yekurapa mumiriri / cheni inotambanudza ye polyurethane (PU) thermoplastic elastomers. PPDI-yakavakirwa kukanda elastomers inoratidzwa ine yakanakisa simba rekuita. Mukana uri pachena ndewekuti mavhiri akakwira-kumhanya anogadzirwa nePPDI anogona kumiririra tembiricha yakakwira pasi pekukurumidza uye kuenderera kushanda / kufamba. Saka, PPDI-yakavakirwa mavhiri ndiyo mhinduro yakanaka kune izvo zvinoda hupenyu hurefu hwekumhanya, hombe yekurodha uye yakakwirira kupisa kupisa zvinoda. Kazhinji, PU elastomers inoratidzirwa neakanakisa abrasion, kubvarura uye kucheka kuramba uchienzanisa neanogadzira rubber. Kunyangwe PPDI neMDI zvine maumbirwo akafanana, kuoma uye modulus zvivakwa zvichienzaniswa neTODI, isocyanate ine yakaderera molar ratio ye polyol kune polyol muPPDI. Chaizvoizvo, iyo PPDI-mhando elastomers inochinjika kupfuura yechinyakare MDI-mhando uye TODI-mhando polyurethane elastomers. Pakati pese polyurethane elastomers, PPDI-yakavakirwa iyo inozivikanwa neiyo yakanyanya kusimbiswa mavhiri, kureva matai e forklift, mota uye ndege; kutungamira rollers, mavhiri emichina; high speed skate rollers uye zvichingodaro. Muchidimbu, PPDI-mhando elastomer ndiyo yakanakira sarudzo kune yakaderera abrasion uye Yepamusoro tembiricha. Mazuva ano, PPDI yekurapa mumiririri inoshandiswa zvakanyanya muTPU-zvigadzirwa senge main chain extender, uye chishandiso chinoramba chichiwedzera, kusanganisira O-mhete, hydraulic seals, coupling nyeredzi uye skrini inodhinda squeegee blades.
Mabhenefiti ayo anoshamisa mabhenefiti ekupisa, abrasion, kubvarura uye kucheka kuramba, PPDI-yakavakirwa elastomers inoshandiswa zvakanyanya kumaindasitiri ayo anoda kuoma kusachinja, kupisa-kusimba mabasa. PPDI ndiye mutambi akakosha muTPU (thermoplastic polyurethane elastomer). Zvisimbiso zveHydraulic, wipers, piston seals, O-mhete, zvisimbiso zvetsvimbo, mapulley ayo aikumbira kupikisa kupisa uye kuramba kudzvinyirira mamwe minda yakakosha yePPDI yekurapa mumiririri. Tisingarevi matayi eforogo, mota, michina, ndege nemapulley, mavhiri, kutungamira ma roller ekunyorovesa zvinhu izvo zviri chimwe chikamu chePPDI-mhando elastomers.
Kurongedza: 20kg, 40kg, 50kg / iron dhiramu.
Kuchengeta uye chekufambisa: PPDI inonzwa zvakanyanya kune unyoro. Mvura inopindirana neese diisocyanates kuti igadzire zvisinganyunguriki urea zvinobva. Usaise PPDI pamwe nechikafu uye kudzivirira kufumura munzvimbo iri pamusoro pe30 ℃. Mushure mekushandisa, chivharo chinofanira kuvharwa nekukurumidza kana paine kusashanda. Pasi pemamiriro akakodzera ekunze, PPDI inoshanda kwemwedzi mitanhatu ingangoita kubva pazuva rainounzwa.
