Igipimo cya Polyol na isocyanate:

Polyol ifite agaciro ka hydroxyl nyinshi n'uburemere bwinshi bwa molekile, bizongera ubucucike bw'imirongo ihuza kandi bigafasha kunoza ubucucike bw'ifuro. Guhindura igipimo cya isocyanate, ni ukuvuga igipimo cya molar cya isocyanate na hydrogen ikora muri polyol, byongera urugero rw'imirongo ihuza kandi byongera ubucucike. Muri rusange, igipimo cya isocyanate kiri hagati ya 1.0-1.2.

 

Guhitamo n'ingano y'umuti utera ifuro:

Ubwoko n'ingano y'ikintu gitanga ifuro bigira ingaruka ku buryo butaziguye ku muvuduko wo kwaguka k'umwuka no ku bucucike bw'ibice nyuma yo gutanga ifuro, hanyuma bikagira ingaruka ku bugari bw'igishishwa. Kugabanya ingano y'ikintu gitanga ifuro bishobora kugabanya imyenge y'ifuro no kongera ubucucike. Urugero, amazi, nk'ikintu gitanga ifuro, agirana na isocyanate kugira ngo akore dioxyde de carbone. Kongera ingano y'amazi bizagabanya ubucucike bw'ifuro, kandi ingano y'inyongera yayo igomba kugenzurwa neza.

 

Ingano ya katalisiti:

Katalyst igomba kwemeza ko ifuro riva n'ivurwa rya gel mu gihe cyo gusohora ifuro bigera ku buringanire buhamye, bitabaye ibyo hazagwa cyangwa hagacika intege. Mu kongeramo imvange ya amine ifite alkaline nyinshi ifite ingaruka zikomeye ku ivurwa riva n'ingaruka zikomeye ku ivurwa riva, hashobora kuboneka katalyst ikwiriye sisitemu yo kwisiga uruhu.

 

Kugenzura ubushyuhe:

Ubushyuhe bw'ibihumyo: Ubunini bw'uruhu buzagenda bwiyongera uko ubushyuhe bw'ibihumyo bugabanuka. Kongera ubushyuhe bw'ibihumyo bizihutisha umuvuduko w'ibihumyo, ibyo bikaba byorohereza gukora imiterere ikomeye, bityo bikongera ubucucike, ariko ubushyuhe bwinshi bushobora gutuma imikorere idahwitse. Muri rusange, ubushyuhe bw'ibihumyo bugenzurwa kuri 40-80°C.

 

Ubushyuhe bwo gushariza:

Kugenzura ubushyuhe bushaje kugeza kuri 30-60°C n'igihe kigera kuri 30-iminota 7 bishobora kubona uburinganire bwiza hagati y'imbaraga zo gukuraho no gukora neza kw'umusaruro w'umusaruro.

 

Kugenzura umuvuduko:

Kongera umuvuduko mu gihe cyo gusohora ifuro bishobora kubuza kwaguka kw'udupira, bigatuma imiterere y'ifuro iba nto, kandi bikongera ubucucike. Ariko, umuvuduko ukabije uzongera ibisabwa ku ifuro kandi bikongera ikiguzi.

 

Umuvuduko wo gukangura:

Kongera umuvuduko wo gukangura neza bishobora gutuma ibikoresho fatizo bivanga neza, bigatanga umusaruro mwinshi, kandi bigafasha kongera ubucucike. Ariko, umuvuduko wo gukangura vuba cyane uzamura umwuka mwinshi cyane, bigatuma ubucucike bugabanuka, kandi muri rusange bigagenzurwa kuri 1000-5000 rpm.

 

Igipimo cyo kuzuza byinshi:

Ingano y'uruvange rw'ibikomoka ku ruhu rwonyine igomba kuba nini cyane kuruta ingano y'uruvange rw'ibikomoka ku ruhu. Bitewe n'uburyo ibicuruzwa n'ibikoresho bikoreshwa, igipimo cyo kuzuza cyane muri rusange ni 50%-100% kugira ngo bigumane umuvuduko mwinshi w'ibihumyo, ibyo bikaba bituma ifuro rishongera mu ruhu.

 

Igihe cyo kugabanya urwego rw'uruhu:

Nyuma yo gusukwa polyurethane irimo ifuro muri iyo moderi, uko ubuso bugenda burushaho kuba ndende, niko uruhu rurushaho kuba rwinshi. Kugenzura neza igihe cyo gupima nyuma yo gusukwa nabyo ni bumwe mu buryo bwo kugenzura ubunini bw'uruhu.
