Polyol kunye ne-isocyanate ratio:

I-Polyol inexabiso eliphezulu le-hydroxyl kunye nobunzima obukhulu be-molecular, obuya kwandisa ubuninzi be-crosslinking kunye nokunceda ukuphucula ubuninzi be-foam. Ukulungelelanisa isalathisi se-isocyanate, oko kukuthi, umlinganiselo we-molar we-isocyanate kwi-hydrogen esebenzayo kwi-polyol, uya kwandisa i-degree of crosslinking kunye nokwandisa ubuninzi. Ngokuqhelekileyo, isalathisi se-isocyanate siphakathi kwe-1.0-1.2.

 

Ukukhethwa kunye nomthamo we-ejenti yogwebu:

Uhlobo kunye nedosi ye-ejenti yogwebu ichaphazela ngokuthe ngqo izinga lokwandiswa komoya kunye nokuxinana kweqamza emva kogwebu, kwaye emva koko kuchaphazele ubukhulu be-crust. Ukunciphisa i-dosage ye-agent ye-foam emzimbeni kunokunciphisa i-porosity ye-foam kunye nokwandisa ubuninzi. Umzekelo, amanzi, njengekhemikhali ekhupha ugwebu, adibana ne-isocyanate ukuze enze ikharbon diokside. Ukwandisa umthamo wamanzi kuya kunciphisa ubuninzi be-foam, kwaye ukongeza kwayo kufuneka kulawulwe ngokungqongqo.

 

Isixa se-catalyst:

I-catalyst kufuneka iqinisekise ukuba i-reaction ye-foaming kunye ne-gel reaction kwinkqubo ye-foaming ifikelela kwi-balance balance, ngaphandle koko i-bubble fallpse okanye i-shrinkage iya kwenzeka. Ngokudibanisa i-alkaline tertiary amine ikhompawundi enefuthe elinamandla le-catalytic kwi-reaction ye-foaming kunye nesiphumo esinamandla kwi-reaction ye-gel, i-catalyst efanelekileyo kwi-self-skinning system inokufumaneka.

 

Ulawulo lobushushu:

Ubushushu bomngundo: Ubukhulu bolusu buya kwanda njengoko ubushushu bokungunda buncipha. Ukonyusa iqondo lobushushu lokungunda kuyakukhawulezisa umlinganiselo wokusabela, nto leyo enceda ekwenzeni ubume obuxineneyo, ngokwenjenjalo kwandisa ukuxinana, kodwa ubushushu obuphezulu kakhulu bunokubangela ukuba impendulo iphume kulawulo. Ngokuqhelekileyo, iqondo lobushushu lokungunda lilawulwa kwi-40-80 ℃.

 

Ukuvuthwa kobushushu:

Ukulawula ubushushu bokuguga ukuya kwi-30-60 ℃ kunye nexesha ukuya kwi-30s-7min linokufumana ibhalansi efanelekileyo phakathi kwamandla okunciphisa kunye nokusebenza kakuhle kwemveliso yemveliso.

 

Ulawulo loxinzelelo:

Ukwandisa uxinzelelo ngexesha lenkqubo ye-foaming kunokuthintela ukwandiswa kweebhubhu, ukwenza isakhiwo se-foam sidibanise ngakumbi, kwaye sandise ubuninzi. Nangona kunjalo, uxinzelelo olugqithisileyo luya kwandisa iimfuno zokubumba kunye nokunyusa iindleko.

 

Isantya sokuvuselela:

Ukunyusa ngokufanelekileyo isantya esishukumisayo kunokwenza ukuba izinto eziluhlaza zixube ngokulinganayo, zisabele ngokupheleleyo, kwaye zincede ukwandisa ukuxinana. Nangona kunjalo, isantya esishukumisayo esikhawulezayo siya kuzisa umoya omninzi, okukhokelela ekunciphiseni koxinzelelo, kwaye ngokuqhelekileyo kulawulwa kwi-1000-5000 rpm.

 

Ukuzalisa i-coefficient:

Isixa sokutofa somxube wokusabela wemveliso yokuzikhupha kufuneka sibe sikhulu kakhulu kunesixa senaliti yokukhupha amagwebu simahla. Ngokuxhomekeke kwimveliso kunye nenkqubo yezinto eziphathekayo, i-coefficient yokuzalisa ngokugqithisileyo ngokuqhelekileyo i-50% -100% ukugcina uxinzelelo oluphezulu lokungunda, olulungele ukuxutywa kwe-agent ye-foaming kwi-skin layer.

 

Ixesha lokulinganisa umaleko wolusu:

Emva kokuba i-polyurethane ene-foam igalelwe kwimodeli, ixesha elide lihlala lilinganisa, ulusu luqina. Ukulawula okunengqiqo kwexesha lokulinganisa emva kokugalela kwakhona enye yeendlela zokulawula ubukhulu besikhumba.
