Ikigereranyo cya Polyol na isocyanate:

Polyol ifite hydroxyl ifite agaciro kanini hamwe nuburemere bunini bwa molekile, bizongera ubwuzuzanye kandi bifashe kuzamura ubwinshi bwifuro. Guhindura indangagaciro ya isocyanate, ni ukuvuga igipimo cya molarike ya isocyanate na hydrogène ikora muri polyol, bizongera urwego rwo guhuza no kongera ubucucike. Mubisanzwe, indangagaciro ya isocyanate iri hagati ya 1.0-1.2.

 

Guhitamo hamwe na dosiye yumukozi ubira ifuro:

Ubwoko na dosiye yumubyimba bigira ingaruka kuburyo butaziguye kwaguka kwikirere nubucucike bwinshi nyuma yo kubira ifuro, hanyuma bikagira ingaruka kubyimbye. Kugabanya urugero rwibintu bifata ifuro birashobora kugabanya ububobere bwifuro kandi byongera ubucucike. Kurugero, amazi, nkimiti ifata imiti, ifata isocyanate kubyara dioxyde de carbone. Kongera amazi bizagabanya ubwinshi bwifuro, kandi umubare wongeyeho ugomba kugenzurwa cyane.

 

Ingano ya catalizator:

Catalizator igomba kwemeza ko reaction ya furo na gel reaction muburyo bwo kubira ifuro igera ku ntera ishimishije, bitabaye ibyo gusenyuka cyangwa kugabanuka bizabaho. Muguhuza ibice byinshi bya alkaline ya gatatu ya amine ifite ingaruka zikomeye za catalitiki kumyuka ifuro hamwe ningaruka zikomeye za catalitike kuri reaction ya gel, cataliste ikwiranye na sisitemu yo kwipimisha.

 

Kugenzura ubushyuhe:

Ubushyuhe bwubushyuhe: Ubunini bwuruhu buziyongera uko ubushyuhe bwibumba bugabanuka. Kongera ubushyuhe bwububiko bizihutisha igipimo cyibisubizo, bifasha gukora imiterere yuzuye, bityo byongere ubwinshi, ariko ubushyuhe bwinshi cyane bushobora gutuma reaction idasohoka. Mubisanzwe, ubushyuhe bwububiko bugenzurwa kuri 40-80 ℃.

 

Ubushyuhe bwera:

Kugenzura ubushyuhe bwo gusaza kugeza 30-60 ℃ nigihe cyo kugeza 30s-7min birashobora kubona uburinganire bwiza hagati yimbaraga zimanuka nubushobozi bwibicuruzwa.

 

Kugenzura igitutu:

Kongera umuvuduko mugihe cyo kubira ifuro birashobora kubuza kwaguka kwinshi, gutuma imiterere ya furo irushaho gukomera, no kongera ubucucike. Ariko, umuvuduko ukabije uzongera ibisabwa kubibumbano kandi byongere igiciro.

 

Umuvuduko ukabije:

Kongera neza umuvuduko ukabije birashobora gutuma ibikoresho bibisi bivanga neza, bikabyitwaramo neza, kandi bigafasha kongera ubucucike. Nyamara, umuvuduko ukabije wihuta uzana umwuka mwinshi, bikavamo kugabanuka kwubucucike, kandi mubisanzwe bigenzurwa kuri 1000-5000 rpm.

 

Coefficient yuzuye:

Ingano yo gutera inshinge zivanze nigicuruzwa cyo kwisiga ubwacyo zigomba kuba nyinshi kurenza inshinge zatewe nubusa. Ukurikije ibicuruzwa na sisitemu yibikoresho, coefficient yuzuye muri rusange ni 50% -100% kugirango igumane umuvuduko mwinshi, ibyo bikaba bifasha kwanduza ibintu byifuro byinshi muruhu.

 

Igihe cyo kuringaniza uruhu:

Nyuma ya polyurethane yuzuye ifuro isutswe muri moderi, uburebure buringaniye buringaniye, uruhu runini. Kugenzura neza igihe cyo kuringaniza nyuma yo gusuka nubundi buryo bwo kugenzura ubunini bwuruhu.
