Duroplast vs thermoplastic rooj zaum

Sab saum toj Viewed Articles

Rau cov khoom siv Duroplast thiab PP, lawv ob leeg yog cov yas.

Qhov txawv: Duroplast nws yog Thermosetting yas, PP nws yog Thermoplastic.

Cov khoom siv raw, cov txheej txheem tsim khoom ntawm ob hom chav tso quav no sib txawv heev.

Duroplast lub rooj zaum tso quav (tseem hu ua UF lub rooj zaum tso quav) yog hom yas tshiab. Nws yog tsim los ntawm cov khoom siv raw thiab tom qab ntawd nias rau hauv hmoov ntawm qhov kub thiab txias. Cov txheej txheem compression molding yog siv. UF lub rooj zaum hauv chav dej muaj qhov zoo nkauj ceramic, siab gloss, ruaj khov xim thiab khawb tsis kam. Muaj zog, ruaj khov, tsis yooj yim rau hnub nyoog, ploj mus, kev ua haujlwm ruaj khov, tiv taus qee yam tshuaj, tuaj yeem ua rau lub cev tsis zoo tom qab muab pov tseg, thiab yuav tsis ua rau muaj kuab paug. Qhov tsis zoo yog tias nws tsis tiv taus kev poob.

Lub rooj zaum tso quav ua los ntawm PP yog ua los ntawm cov ntshiab PP raw mov los ntawm kub-melting molding, thiab cov txheej txheem txhaj tshuaj molding yog siv. Qhov tsis zoo yog tias nws tsis khawb-resistant.

Ob lub rooj zaum tso quav tso quav muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab tus nqi ntawm cov rooj zaum hauv chav dej urea yuav kim dua me ntsis.
