Mafuro anochinjika epolyurethane anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekupfava kwawo, kugara kwenguva refu, uye kushanduka-shanduka. Basa remafuro epolyurethane mukugadzirwa kwaro rakakosha pakuwana hunhu hwaunoda senge kufanana kwemaburi, kusimba, uye kunamira kwakawedzerwa. Mafuro maviri chaiwo, MXC-BDMA neMXC-70, anoratidza kukosha kwemafuro akasarudzwa nokungwarira mumafomura anochinjika efuro.
1. MXC-BDMA (CAS 103-83-3)- Benzyl Dimethylamine Catalyst
MXC-BDMA chinhu chinoshandiswa zvakanyanya mu polyester polyurethane bulk soft foam, polyurethane rigid foam, uye sheet and glue coatings. Kunyangwe ichinyanya kushandiswa mu rigid foam, ine mabhenefiti akakosha mukugadzira furo rinochinjika:
- Kuyerera Kwemvura Kwekutanga:MXC-BDMA inoita kuti ivhu ritange kuyerera zvakanaka, zvichiita kuti musanganiswa wepolyurethane upinde zvakanaka muzviumbwa, izvo zvakakosha pakushandisa furo rinochinjika.
- Maburi Akafanana:Chinhu chinobatsira pakuumbwa kwemasero efoam akafanana uye akarongeka zvakanaka. Kufanana kwemaumbirwo emasero kwakakosha kuti pave neunhu hwakafanana hwefoam hwakaita sehutete uye husimba.
- Kuvandudza Kunamira:Pakushandisa zvinoda kuti furo ribatane ne substrate, MXC-BDMA inovandudza kunamira, zvichiita kuti chigadzirwa chigare kwenguva refu uye chakasimba.
2. MXC-70 (CAS 1739-84-0)- Chinokonzeresa Amine
MXC-70 chimwe chinhu chinobatsira zvikuru, chinonyanya kushandiswa mukugadzira furo rakasimba asi chine mabhenefiti makuru mukugadzira furo rinochinjika, kunyanya mufuro rinochinjika rakasimba (HR) uye mabhuroko ane ester-based:
- Kuvandudza Kupora uye Kusaoma Kweganda:Iyi catalyst inobva kuamine inowedzera maitiro ekupisa, inoderedza kuputsika kwechigadzirwa chekupedzisira, zvichiita kuti furo rive nyore kuchinjika uye risatsemuke.
- Kuvandudza Simba reGreen:MXC-70 inovandudzawo simba regirini refuro, zvichiita kuti rishande zviri nani pakutanga kwekugadzirwa. Hunhu uhwu hunonyanya kubatsira kune furo rinochinjika rinoshandiswa mumotokari uye mumidziyo yemumba, uko kugara kwenguva refu kwakakosha.
- Kuchinjika Kwekushandisa:Chinokonzeresa chinoshanda zvakanaka nepolyester yakakangwa uye mafomura akavakirwa pa ester, zvichipa mukana wekugadzirwa kwemafuro anochinjika anoshanda zvakanyanya.
Chinyorwa chino chinogona kutsanangura kuti ma "catalysts" ese ari maviri anovandudza sei mashandiro e "furo", zvichiratidza simba rawo pachimiro chemasero akafanana uye kugara kwenguva refu, izvo zvakakosha pakushandisa kwekupedzisira senge fenicha, magumbeze, zvigaro zvemotokari, uye insulation.
