Polyurethane yagara ichizivikanwa sechinhu chinochinjika zvakanyanya, uye kushandiswa kwayo kwakasiyana-siyana kunoita kuti ive sarudzo yakakodzera kushandiswa kwakasiyana-siyana mumaindasitiri, kunyanya muCoatings, Adhesives, Sealants, uye Elastomers (CASE). Mashandisirwo aya anoda macatalyst anoshanda zvakanyanya anogona kugadzirisa reaction kinetics uku achivimbisa kushanda zvakanaka kwechigadzirwa. Kune vagadziri vema polyurethane systems, kusarudza catalyst yakakodzera kwakakosha pakuenzanisa kushanda zvakanaka, kuchengetedzeka, uye kugara kwenguva refu kwechigadzirwa.
Mhando dzedu dzema "polyurethane catalysts" anoshanda zvakanaka dzinopa mhinduro dzakagadzirirwa zvinodiwa zvema "CASE applications", zvichibatsira ma "formulators" kuwana hunhu hwakanaka hwakadai sekunamatira, kuchinjika, uye kuramba zvinhu zvakatikomberedza. Pakati pema "catalysts" edu anotungamira,MXC-R70(2-(2-dimethylaminoethoxy)ethanol, CAS 1704-62-7) inonyatsozivikanwa nekushanda kwayo uye kukodzera kwayo mumhando dzakasiyana dzemafuro uye zvigadzirwa zve elastomeric.
Basa reZvinokonzeramuCASE Applications
MaCatalyst anoshanda semusana wemakemikari anoshandura maformula emvura epolyurethane kuita zvigadzirwa zvinogara kwenguva refu uye zvinoshanda zvakanyanya. Anokurumidza kuburitsa furo (kuvhuvhuta) uye kupodza (gelling), zvichiita kuti chigadzirwa chekupedzisira chive nehunhu hwemakanika uye hwepanyama hunodiwa.
Mukushandiswa kweCASE, izvi zvinoreva kuwedzera zvinhu zvakakosha zvakaita se:
- Kunamatira: Kuve nechokwadi chekuti pane kubatana kwakasimba pakati pezvinhu, izvo zvakakosha muzvinonamira nezvinovhara.
- Kuchinjika uye Kugara Kwenguva refu: Kuwana kusimba kwenguva refu uye kuramba kupfeka muma elastomers.
- Kupedzisa Kwepamusoro: Kuvandudza kufanana uye runako rwemapendi.
- Kubudirira Kwekugadzirisa: Kubatsira kukurumidza kugadzirwa kwezvigadzirwa nenguva dzakagadziriswa dzekurapa.
Mashandisirwo Akakosha eMXC-R70zvikazo
MXC-R70, chinhu chinobatsira kunyungudika chinonzi volatile amine catalyst, chinoita basa guru mukugadzira zvigadzirwa zvakasiyana-siyana zvakagadzirwa nepolyurethane, zvinosanganisira ma microcellular foams nema elastomers. Kushanda kwayo zvakanyanya kunoita kuti ive yakakodzera vinyl foam form dzakadai semota dashboards nema headrests, uko kunodiwa kunyatsoita uye kugara kwenguva refu. Nekukurudzira kukurumidza kupora pasina kukanganisa kuchinjika uye kunyaradzwa kwefoam, MXC-R70 yakakosha kumashandisirwo anoda kushanda kwepamusoro uye kunyaradzwa.
Zvinhu Zvikuru zveMXC-R70:
- Kugadzirisa zvakanyanya: Inobvumira nguva yekukurumidza uye inoshanda zvakanaka mukuita kwefuro uye kupora.
- Mashandisirwo akasiyana-siyana: Yakakodzera kushandiswa kwakasiyana-siyana, kubva kuma microcellular foam kusvika kuma elastomers, ichipa hunhu hwakanaka hwemuviri mune yega yega application.
- Chepfu yakaderera: Inoderedza kuvimba nezvinhu zvine chepfu zvakaita se dibutyltin, zvichiita kuti vashandi nevagadziri vagare vakachengeteka pakugadzira.
Kuderedza Kusangana Nezvinhu Zvine Chepfu Zvinokonzera Huturu
Dambudziko riri kukura muindasitiri yepolyurethane nderekuderedza kubatwa nezvinhu zvine chepfu zvakaita sedibutyltin. Mhando dzedu itsva dzezvinhu zvine chepfu, zvinosanganisira MXC-R70, dzinopa imwe nzira yakachengeteka nekuderedza kana kubvisa kudiwa kwezvinhu izvi zvinokuvadza. Izvi hazvingogadzirisi kuchengetedzeka kwebasa chete asiwo zvinoenderana nemitemo yezvakatipoteredza iri kuchinja uye zvinodiwa nevatengi kune zvigadzirwa zvakachena uye zvakasvibira.
