Mafuro epolyurethane anoshandiswa zvakanyanya mumabasa akasiyana-siyana nekuda kwehunhu hwawo hwakanaka hwekudzivirira kupisa uye kusimba kwechimiro. Rumwe rudzi rwakakosha rwefuro repolyurethane ifuro remaseru akavharwa, rinozivikanwa nekuomarara kwaro uye kugara kwenguva refu. Semupi wezvinhu zvinogadzira polyurethane, tinoziva kukosha kwekunzwisisa hunhu uye mashandisirwo efuro remaseru akavharwa, pamwe nebasa rezvinhu zvinogadzira senge MXC-C15 neMXC-A33 mukugadzirwa kwazvo.
Kuziva Foam Yemasero Akavharwa
Furo remasero akavharwa rinosiyaniswa nechimiro charo chakakora uye chakamanikana, uko sero rega rega rakavharirwa zvakakwana uye rakasungirirwa pamwe chete. Chimiro ichi chakasiyana chinopa furo remasero akavharwa hunhu hwakasiyana:
1. Huremu uye Kurema: Furo rine masero akavharwa rakakora uye rinorema zvikuru kana tichienzanisa nefuro rine masero akazaruka. Kuwanda uku kunobatsira kuti rive nemasimba ekudzivirira kupisa uye kuti rive rakakwana.
2. Kudzivirira Mvura: Chimwe chezvinhu zvinonyanya kuzivikanwa nefuro rine masero akavharwa ndechekudzivirira kwaro mvura zvakanaka. Kusiyana nefuro rine masero akazaruka, furo rine masero akavharwa haritore mvura, zvichiita kuti rive rakakodzera kushandiswa uko kudzivirira hunyoro kwakakosha.
3. Kudzivirira Kupisa: Furo remaseru akavharwa rinopa kudzivirira kupisa kwakanyanya nekuda kwechimiro charo chemaseru madiki. Rine R-value yakakwira, zvichireva kuti rinoshanda zvakanyanya pakudzivirira kutamiswa kwekupisa.
4. Kuomarara: Kuomarara kwefuro kunoita kuti rikwanise kushandiswa zvinoda rutsigiro rwakawedzerwa rwechimiro. Rinoramba rakaita chimiro charo pasi pekumanikidzwa uye rinopa nzvimbo yakagadzikana.
Mashandisirwo eFoam yeMasero Akavharwa
Foam yepolyurethane inoshandiswa mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hunobatsira. Mamwe mashandisirwo akajairika anosanganisira:
- Kudzivirira Dzimba: Foam ine mavharo inoshandiswa zvakanyanya mukuvaka kudzivirira madziro, matenga, uye nheyo. Kukosha kwayo kwepamusoro-soro kunobatsira kuchengetedza tembiricha yemukati, zvichideredza mari yekushandisa simba.
- Zvishandiso zveFlotation: Nekuda kwekusanyorova uye kusanyorova kwemvura, furo remaseru akavharwa rinoshandiswa mukugadzira majasi ekuchengetedza hupenyu, zvinhu zvinobatsira pakunyorova, nezvimwe zvishandiso zveflotation.
- Kurongedza: Kusimba kwefuro uye hunhu hwekudzivirira kunoita kuti rive rakakodzera kurongedza zvinhu zvisina kusimba, zvichiita kuti zvirambe zvakachengeteka panguva yekufambisa.
- Mota: Muindasitiri yemotokari, furo remaseru akavharwa rinoshandiswa kudzivirira ruzha uye kudzivirira kupisa mumotokari.
Basa reCatalysts mukugadzirwa kweFoam yeMasero Akavharwa
MaCatalyst anoita basa rakakosha mukugadzirwa kwefuro repolyurethane rakavharirwa, zvichikanganisa hunhu hwefuro uye mashandiro aro. Zvinhu zvakajairwa, zvakaita seMXC-C15 neMXC-A33, zvinoshandiswa kugadzirisa hunhu hwefuro:
- MXC-C15: Iyi catalyst inonyanya kushandiswa mukugadzira zvinhu zvinochinjika uye zvinochinjika zvishoma nezvishoma uye mukushandisa furo rakaomarara. Inogona zvakare kushandiswa mu polyether block foams uye CASE.
- MXC-A33: Ichi chinobatsira chinoshandiswa pakugadzira furo rakapfava, furo rakaoma, furo rakaoma zvishoma. Chinogonawo kuva zvimwe zvinonyungudutsa, zvakaita seMEG, DEG, BDO, nezvimwewo, pakushandisa kwakasiyana-siyana..
Kunzwisisa hunhu uye mashandisirwo efuro repolyurethane rakavharirwa, pamwe nebasa remacatalyst chaiwo, zvakakosha kune vagadziri nevashandisi zvakafanana. Nekusarudza macatalyst akakodzera, akadai seMXC-C15 neMXC-A33, vagadziri vanogona kuve nechokwadi chekuti furo iri rinosangana nezvinodiwa zvemashandisirwo akasiyana-siyana, zvichipa mhinduro dzakavimbika uye dzinoshanda zvakanaka.
