Indlela yokuCoca ngokufanelekileyo Izixhobo zePolyurethane Foam

Umsebenzi wokucoca ngokuchanekileyo awukwazi kuphela ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo, kodwa kunye nokwandisa ngokufanelekileyo ubomi benkonzo yezixhobo zokugwedla.Ngoko ke, kungakhathaliseki ukuba yeyiphi imbono, kubaluleke kakhulu ukucoca izixhobo ze-polyurethane foaming ngokuchanekileyo.

Inkalo ebalulekileyo yokugcinwa kwezixhobo ze-polyurethane foam kukucoca.Xa ucoca izixhobo, nikela ingqalelo kula manqaku alandelayo:

1.Izixhobo zepolyurethaneumbhobho wokufudumeza:

Xa ukutshiza kugqityiwe, cinezela iqhosha lokukhupha uxinzelelo (PARK), uze utshise umpu ukukhulula uxinzelelo malunga ne-500-700psi.Ukunciphisa uxinzelelo kunokupheliswa.Ngenxa yokuba xa kukho uxinzelelo oluthile kumbhobho, ukufuma emoyeni akuyi kungena lula kumbhobho, okuqinisekisa ukuba izinto eziluhlaza aziyi kuchaphazeleka ngumoya omanzi, kwaye izinto ezi-A aziyi kutshabalalisa okanye zidibanise kwipayipi. ;inceda kakhulu.

2. Izinto eziphathekayo Impompo yokumpompa yeizixhobo polyurethane:

Emva kokusetyenziswa, coca inkangeleko yayo kunye ne-agent yokucoca, uze uyifake kwi-casing ekhuselayo kunye ne-agent yokucoca ukuze injini eyintloko itywine, ukwenzela ukuba kuthintelwe inani elincinci lezinto ze-isocyanate ekuphenduleni ngokufuma emoyeni, kubangela isondlo Isantya siyancipha, umlinganiselo wokupompa awukho kwi-balance, kwaye ipompo elinganayo ayinanto.

3. Ukucocwa kweizixhobo polyurethane:

Ukuba ikhefu phakathi kokugqitywa kolu lwakhiwo kunye nolwakhiwo olulandelayo lufikelela ngaphezu kweentsuku ezingama-30, yonke inkqubo ye-A kufuneka icocwe kwaye itywinwe.

4.Izixhobo zokuphola amagwebu ePolyurethane(umatshini wogwebu) isilinda ngokulinganayo:

Ngethuba lokusebenza okuqhelekileyo komatshini we-polyurethane we-foam, nikela ingqalelo kwinkqubo yokuzicoca ye-A cylinder yezinto, nokuba ulwelo olujikelezayo lokucoca lujikeleza ngokuqhelekileyo, nokuba ulwelo lokucoca luye lwaba luthuli, luyikristale, njl., ukuba kukho okungaqhelekanga. ukujikeleza, khangela ukuba umbhobho wokucoca ulwelo uvaliwe, okanye khangela ukuba kukho i-crystallization kwi-cylinder yezinto eziphathekayo;ukuba ulwelo olujikelezayo luyi-turbid kunye nekristali, kufuneka lutshintshwe ngexesha.
