Isilinganiso se-Polyol ne-isocyanate:

I-Polyol inenani eliphezulu le-hydroxyl kanye nesisindo esikhulu sama-molecule, okuzokwandisa ubuningi bokuxhumanisa futhi kusize ekuthuthukiseni ubuningi be-foam. Ukulungisa inkomba ye-isocyanate, okungukuthi, isilinganiso se-molar se-isocyanate ku-hydrogen esebenzayo ku-polyol, kuzokhulisa izinga lokuxhumanisa futhi kwandise ubuningi. Ngokuvamile, inkomba ye-isocyanate iphakathi kuka-1.0-1.2.

 

Ukukhethwa kanye nomthamo we-ejenti yokwenza amagwebu:

Uhlobo kanye nomthamo we-ejenti ekhipha amagwebu kuthinta ngqo izinga lokunwebeka komoya kanye nobuningi bama-bubble ngemva kokukhipha amagwebu, bese kuthinta ukujiya koqweqwe. Ukunciphisa umthamo we-ejenti ekhipha amagwebu ngokomzimba kunganciphisa ukubhoboka kwegwebu futhi kwandise ubuningi. Isibonelo, amanzi, njenge-ejenti ekhipha amagwebu yamakhemikhali, asabela ne-isocyanate ukuze akhiqize i-carbon dioxide. Ukwandisa inani lamanzi kuzonciphisa ubuningi begwebu, futhi inani lokwengeza kwawo lidinga ukulawulwa ngokuqinile.

 

Inani le-catalyst:

I-catalyst kumele iqinisekise ukuthi ukusabela kwe-foam kanye nokusabela kwe-gel enkambisweni ye-foam kufinyelela ibhalansi eguquguqukayo, ngaphandle kwalokho kuzokwenzeka ukuwohloka kwe-bubble noma ukuncishiswa. Ngokuhlanganisa i-compound ye-tertiary amine enamandla ene-alkaline enamandla enomthelela omkhulu we-catalytic ekusabeleni kwe-foam kanye nomphumela we-catalytic onamandla ekusabeleni kwe-gel, i-catalyst efanele uhlelo lokuzikhuhla ingatholakala.

 

Ukulawula izinga lokushisa:

Izinga lokushisa lesikhunta: Ubukhulu besikhumba buzokhula njengoba izinga lokushisa lesikhunta lehla. Ukwandisa izinga lokushisa lesikhunta kuzosheshisa izinga lokusabela, okusiza ekwakheni isakhiwo esiminyene, ngaleyo ndlela kwandiswe ubuningi, kodwa izinga lokushisa eliphakeme kakhulu lingabangela ukusabela kuphume ekulawuleni. Ngokuvamile, izinga lokushisa lesikhunta lilawulwa ku-40-80℃.

 

Izinga lokushisa lokuvuthwa:

Ukulawula izinga lokushisa lokuguga libe ngu-30-60℃ kanye nesikhathi esifinyelela kumaminithi angu-30-7 kungathola ibhalansi efanele phakathi kwamandla okususa kanye nokusebenza kahle komkhiqizo.

 

Ukulawula ingcindezi:

Ukwandisa ingcindezi ngesikhathi senqubo yokwenza amagwebu kungavimbela ukwanda kwamagwebu, kwenze isakhiwo segwebu sibe sincane kakhulu, futhi kwandise ubuningi. Kodwa-ke, ingcindezi enkulu izokwandisa izidingo zesikhunta futhi inyuse izindleko.

 

Isivinini sokuxubha:

Ukwandisa isivinini sokuxubha kahle kungenza izinto zokusetshenziswa zixubane ngokulinganayo, zisabele ngokugcwele, futhi zisize ekwandiseni ubuningi. Kodwa-ke, isivinini sokuxubha esisheshayo sizoletha umoya omningi kakhulu, okuholela ekwehleni kobuningi, futhi ngokuvamile kulawulwa ku-1000-5000 rpm.

 

I-coefficient yokugcwalisa ngokweqile:

Inani lomjovo wengxube yokusabela komkhiqizo ozikhuhlayo kufanele libe likhulu kakhulu kunenani lomjovo we-foam yamahhala. Kuye ngomkhiqizo kanye nohlelo lwezinto, i-coefficient yokugcwalisa ngokweqile ngokuvamile ingu-50%-100% ukuze kulondolozwe umfutho ophezulu wesikhunta, okusiza ekuncibilikeni kwe-ejenti ekhuhlayo esikhumbeni.

 

Isikhathi sokulinganisa ungqimba lwesikhumba:

Ngemva kokuba i-polyurethane enegwebu ithululelwe kumodeli, uma indawo ilingana isikhathi eside, isikhumba siba sikhudlwana. Ukulawula isikhathi sokulinganisa ngemva kokuthulula nakho kungenye yezindlela zokulawula ukujiya kwesikhumba.
