Furo reViscoelastic (VE furo), inozivikanwawo se memory foam, ipurasitiki inoshanda zvakanyanya inoshandiswa zvakanyanya mumatiresi, mapillow, zvigaro zvemotokari, uye macushion emumaindasitiri. Hunhu hwayo hwakasiyana hwe rebound inononoka uye inotenderera muviri hunobva mukuita kwe polyurethane reaction inodzorwa nokungwarira - uye pakati peizvi ndipo panepolyurethane catalyst.
Kunzwisisa VE Foam uye Kugadzirwa Kwayo
Furo reVE rinogadzirwa nekuita reactivepolyolsneisocyanatespamberi pemvura, zvinhu zvinofefetera, zvinhu zvinonyungudutsa, uyezvinokonzeresa polyurethaneKuita uku kunoumba chimiro chemasero chinosanganisa kuchinjika nekupinza simba.
Chinhu chikuru chekugadzira furo reVE remhando yepamusoro ndechekudzora maitiro maviri akakosha:
- Kuita kweGelling- Kuita pakati pemapolyol nemaisocyanates, ayo anoumba network yepolyurethane polymer.
- Kuita kwemhepo- Kuita kwemvura nema isocyanates, izvo zvinoburitsa CO₂ gasi kuti rigadzire masero efuro.
Pasina kudzora kwakanyatsojeka maitiro aya, huwandu hwefuro, kupfava kwaro, nguva yekupora kwaro, uye kugara kwenguva refu kwaro zvinogona kusiyana, zvichikonzera kushanda kwaro kusingaenderane.
Basa rePolyurethane Catalysts
Zvinhu zvinokonzeresa polyurethanekukurumidza uye kuenzana kwemaitiro e gelling ne blowing, zvichibvumira vagadziri kuwana chimiro chemasero chaiwo uye hunhu hwemuviri hunodiwa kune VE foam. Izvi zvinogona kukamurwa zvakanyanya kuita mhando mbiri:
- Zvinokonzera amine- Zvinonyanya kukurudzira kufefetera, zvichikanganisa kupfava kwefuro, huwandu hwemasero akavhurika, uye kufamba kwemhepo.
- Zvinokonzera simbi- Zvinonyanya kukurudzira maitiro ekugadzira gelling, zvichikanganisa kusimba kwefuro, simba rekudhonza, uye kugadzikana.
Mukugadzirwa kwefuro reVE, musanganiswa weamine nesimbi wakagadzirwa nokungwarirazvinokonzeresa polyurethaneinoshandiswa kugadzirisa chimiro chemhinduro.
Nheyo yeCatalyst Function muVE Foam
Pfungwa yekushandisa polyurethane catalysts mukugadzira furo reVE yakavakirwa pakukurumidza kusarudza. Ma catalyst akasiyana ane hukama hwakasiyana hwemakemikari anobatanidzwa mukuita kukuru uku. Nekusarudza musanganiswa we catalyst wakakodzera uye chiyero, vagadziri vanogona:
- Nguva yekukwira kwesimba rekutonga- Kudzivirira kuputsika uye kuona kuti furo rinokura zvakaenzana.
- Gadzirisa chimiro chemasero- Kuwana dhizaini yemasero akavhurika kwakakosha kuti munhu adzoke zvishoma nezvishoma uye akwanise kufema.
- Kudzikamisa kupfava uye rutsigiro- Kugadzirisa furo kuti rigare kwenguva refu uye rigare zvakanaka.
- Kuvandudza kuenderana- Kuderedza kusiyana kwemhando dzakasiyana-siyana kuti pave nemhando yakavimbika.
Semuenzaniso, mu memory foam, kuita zvishoma nezvishoma gelling reaction ne balanced blowing kunobatsira kugadzira significant slow-rebound effect, ukuwo kuchidzivirira kupisa kwakanyanya panguva yekupisa.
Zvinhu Zvinokanganisa Kusarudzwa kweCatalyst
Pakusarudzapolyurethane catalystVagadziri vanofunga nezve furo reVE:
- Kuwanda kwefurouye zvinodiwa zvekuoma.
- Kumhanya kwekuitazvinodiwa pamutsetse wekugadzira (inoenderera mberi vs. batch).
- VOC uye mwero wezvinhu zvinonhuhwirirazvezvigadzirwa zvekunyaradza.
- Kuenderananezvimwe zvinowedzerwa, zvakaita sezvinodzivisa moto kana zvinopenda.
- Mitemo yezvakatipoteredza— kusarudza sarudzo dze catalyst dzinobvisa utsi hushoma uye dzinogara kwenguva refu.

- Kunyaradzwa kwakawedzerwa uye kusununguka kwekumanikidzwa.
- Inogara kwenguva refu uye inotsungirira furo.
- Kudzikira kwezvikanganiso zvakaita sekunge mavanga kana kuderera kweganda.
- Kutevedzera mitemo yezvakatipoteredza uye kuchengetedzeka.
- Kubudirira kukuru mukugadzira uye kuraswa kushoma.
Mhedziso
Kugadzirwa kwefuro re viscoelasticinoda zvinopfuura zvinhu zvakagadzirwa zvakakodzera chete — inoda kudzorwa kwakanyatsojeka kwemakemikari, uyezvinokonzeresa polyurethanendizvo zvakakosha kuti zvibudirire. Nekunzwisisa misimboti yekushanda kwe catalyst uye kusarudza musanganiswa wakakodzera wekushandisa VE foam, vagadziri vanogona kuve nechokwadi chekuti mhando inogara iripo, mashandiro akanaka, uye mukana wekukwikwidzana mumusika.
