Dab tsi yog cov hau kev ntawm ua npuas ncauj ntau lawm
{{01. polyurethane (pu) daim txhuam cev ua npuas
Polyurethane daim txhuam cev yog hom daim txhuam cev feem ntau, uas tau muab faib ua npuas (xws li rooj zaum sib xyaw (xws li cov ntaub ntawv rwb thaiv tsev)}}
2. Cov Qauv Ntau Lawm:
(1) slabstock ua npuas ncauj
Cov Khoom Siv Raw: Polyol + Isocyanate (MDI / MDI) + Dej (Foaming Tus Neeg Sawv Cev) + Caticone Roj (Stabilizer) {{4}
Txheej txheej:
Cov ntaub ntawv nyoos yog tov thiab nchuav rau hauv cov kab txuas ntxiv ua npuas dej .}}
Tshuaj tiv thaiv kev ua lag luam ua rau qhob roj kom ua npuas .
Cov npaus yog solidified thiab txiav mus rau hauv lub qhov xav tau zoo .
Nta: Haum rau huab hwm coj ntau lawm, xws li daim txaj txaj thiab rooj zaum sponges .
(2) Moulded Npuas
Txheej txheej:
Cov sib tov yog txhaj rau hauv cov pwm .
Kub thiab solorify los ua cov duab tshwj xeeb (xws li lub rooj zaum hauv tsheb, insoles) .
Nta: Cov duab nyuaj tuaj yeem ua thiab qhov ceev yog qhov txhawb .
(3) Kev siv zog siab (HR) ua npuas ncauj
Tshwj xeeb polyols tau ntxiv rau kev txhim kho elasticity thiab durability, siv nyob rau hauv cov rooj tog thiab rooj zaum hauv tsheb.
3. Cov Ntsiab Lus:
Tus txhuam tsev ua npuas ncauj tsim khoom tuaj yeem hloov kho lub hardness, elasticity, huab cua permeability thiab lwm yam khoom raws li kev thov lub neej thiab muaj kev lag luam raws li lub neej txhua hnub thiab muaj kev lag luam {}}
