Polyurethane elastomer imhando yezvinhu zvinoshandiswa zvakanyanya, ine kuchinjika kwakanaka, kugara kwenguva refu uye kuramba kupfeka, saka inoshandiswa zvakanyanya mumativi ese ehupenyu. Chimwe chezvinhu zvakakosha mukugadzirwa kwepolyurethane elastomers kushandiswa kwecatalysts dzinokurumidzisa maitiro emakemikari panguva yekuumbwa kwechinhu chekupedzisira. Izvi zvakakosha pakudzora maitiro epolymerization, kuve nechokwadi chekuti hunhu hwaunoda hwe elastomer hwawanikwa. Pakati pemhando dzakasiyana dzecatalysts dziripo, MXC-A33 ine chimiro chakasiyana chinogona kushandiswa mumhando dzakasiyana dze polyurethane foams uye elastomers.
ChiiMXC-A33?
MXC-A33 chinhu chinobatsira kugadzira polyurethane chinowedzera kushanda pakati pema polyol nema isocyanates, izvo zviri zvinhu zvikuru zve polyurethane. Chinhu ichi chinosanganisa 33% TEDA (triethylene diamine) uye 67% DPG (monoconjugated dipropylene glycol). Iyi nzira chaiyo inoita kuti pave nekushanda kwakanaka mukugadzira ma polyurethane foams nema elastomers.
- TEDA (Triethylenediamine): Chinhu chinoshanda zvikuru che tertiary amine catalyst chinokurudzira kuita kwe gelling pakati pemapoka e hydroxyl ne isocyanate.
- DPG (Monoconjugated Dipropylene Glycol): Chinhu chinonyungudutsa chinobatsira kuderedza kusviba uye kuwedzera kusanganiswa kwezvinhu, zvichiita kuti mhinduro iite zvakanaka.
Kushandiswa muPolyurethane Elastomers
MXC-A33 inoshandiswa zvakanyanya mukugadzira ma polyurethane elastomers nekuda kwemhedzisiro yayo yakaringana ye catalytic, iyo inoita kuti polymerization reaction iitike nekukurumidza. Kugadziriswa uku kwakadzorwa kwakakosha pakugadzirwa kwema elastomers ane hunhu hwemakanika hwaunoda senge elasticity, tensile strength uye kusakara.
Chinosimudzira kugadzirwa kwezvimiro zvepolymer zvakabatana zvakafanana, izvo zvinogona kusangana nekushanda kwe elastomers mukushandiswa kwakasimba. Polyurethane elastomers dzakagadzirwa kubva kuMXC-A33 dzinowanzo shandiswa muzvikamu zvemotokari, ma industrial rollers, uye zvisimbiso zvepamusoro, izvo zvinoisa kudiwa kukuru pakusimba kwavo uye kusimba kwavo.
Mhedziso
Kushandiswa kwezvinokonzeresa polyurethaneKufanana neMXC-A33 mukugadzirwa kwe elastomer chinhu chakakosha pakuona kuti chinhu chacho chinoshanda uye chakavimbika. Musanganiswa wayo wakasiyana weTEDA neDPG unoita kuti ishande zvakanaka pakushandisa foam ne elastomer, zvichigonesa vagadziri kugadzira zvigadzirwa zvemhando yepamusoro uye zvinogara kwenguva refu zvemaindasitiri akasiyana-siyana.
