Nzira yekudzivirira sei cavitation mukatipolyurethane furo muchina
1. Nyatsodzora chiyero uye jekiseni vhoriyamu yemhinduro yekutanga
Dzora chiyero chemavara madema, akasanganiswa polyether uye cyclopentane.Pasi pemamiriro ekuti huwandu hwejekiseni hunoramba husina kuchinjwa, kana chikamu chechinhu chitema chakanyanya kukura, cavitation ichaonekwa, kana chikamu chechinhu chichena chakanyanya kukura, mabhubhu akapfava achaonekwa, kana chikamu che cyclopentane chakanyanya kukura, mabhuru. ichaonekwa, uye kana chikamu chiri chidiki kwazvo, cavitation ichaonekwa.Kana chikamu chemavara madema uye machena chisina kuenzana, pachava nekusaenzana kusanganiswa uye shrinkage yefuro.

Kuwanda kwejekiseni kunofanirwa kuenderana nezvinodiwa zvemaitiro.Kana iyo jekiseni yadzikira pane inodiwa maitiro, iyo foam yekuumba density ichave yakaderera, simba richave rakaderera, uye kunyangwe chiitiko chekuzadza incompact vacuoles chichaitika.Kana iyo jekiseni vhoriyamu yakakwira kupfuura zvinodiwa maitiro, pachave nekuwedzera bubble uye kuvuza, uye bhokisi (gonhi) richaremara.
2. Kudzora kwekushisa kwepolyurethane furo muchinandiyo kiyi yekugadzirisa cavitation
Kana tembiricha yanyanya, kuita kwechisimba uye kwakaoma kudzora.Zviri nyore kuoneka kuti kuita kwebubble fluid yakaiswa mubhokisi hombe haina yunifomu.Iyo bubble fluid yakajairwa pakutanga yakave nemakemikari reaction, uye viscosity inowedzera nekukurumidza, uye iyo bubble fluid inojerwa gare gare haisati yaita.Nekuda kweizvozvo, iyo bubble fluid inojairwa gare gare haigone kusunda iyo bubble fluid inojairwa kutanga kumucheto kumberi kwekupupuma kwebhokisi, zvichikonzera cavitation yemuno mubhokisi.
Zvinhu zvitema uye zvichena zvinofanirwa kurapwa patembiricha yenguva dzose isati yapupuma furo, uye tembiricha inopupa inofanirwa kudzorwa pa18 ~ 25 ℃.Kupisa kwechoto chekupisa chemidziyo inopupuma kunofanirwa kudzorwa pa30 ~ 50 ℃, uye tembiricha yeforoma mold inofanirwa kudzorwa pakati pe35 ~ 45 ℃
Kana tembiricha yefoam mold yakadzikira, kuyerera kwefoam-mvura system kwakashata, nguva yekurapa yakareba, mhinduro haina kukwana, uye cavitation inoitika;kana tembiricha yefoam mold yanyanya kukwira, liner yepurasitiki yakakanganiswa nekupisa, uye foam-liquid system inoita zvechisimba.Naizvozvo, tembiricha yefoam mold uye tembiricha yepakati pechoto chinopupuma inofanira kunyatsodzorwa.
Kunyanya munguva yechando, mold inopupuma, choto chinopisa, choto chinoputika, bhokisi uye gonhi zvinofanira kupiswa kweanopfuura maminetsi makumi matatu mangwanani oga oga kana mutsetse unovhurwa.Mushure mekupupa kwenguva yakati muchirimo, furo system inofanira kutonhodzwa.

Kudzvinyirira Kudzora kwePolyurethane Foaming Machine
Kudzvanywa kwemuchina unopupuma kwakadzikira.Iyo yakasviba, chena zvinhu uye cyclopentane haina kusanganiswa zvakafanana, iyo inoratidzwa seyakaenzana density ye polyurethane foam, mabhuru makuru emunharaunda, kupupuma kwefuro, uye nyoro nyoro foam: chena, yero kana dema mitsetse inooneka pafuro , furo rakaputsika.Iko kudzvanywa kwejekiseni yemuchina unopupa ndeye 13 ~ 16MPa
