Core Raw Khoom:
Kev tsim cov pob txha polyurethane ua npuas ncauj feem ntau suav nrog ob pawg loj ntawm cov ntaub ntawv raw: polyol tivthaiv thiab isocyanate tivthaiv.
Cov **polyol tivthaiv** muaj ib tug sib tov ntawm polyether/polyester polyols thiab ntau yam additives -xws li tshuab tshuab, catalysts, thiab ua npuas ncauj stabilizers. Nws tsim cov txheej txheem pob txha ntawm cov npuas dej, reacting nrog cov isocyanate los tsim cov polymer matrix; ib txhij, tus neeg sawv cev tshuab yog lub luag haujlwm rau kev tsim cov roj uas tsim cov qauv ntawm tes.
**isocyanate tivthaiv ** feem ntau yog hais txog polymeric diphenylmethane diisocyanate (paub tias yog polymeric MDI lossis PAPI). It undergoes a chemical reaction with the polyol component, thereby determining the foam's cross-link density and structural strength.
Tus nqi tseem ceeb ntawm cov polyurethane ua npuas ncauj yog nyob rau hauv nws cov khoom tshwj xeeb thermal rwb thaiv tsev, uas yog ua tiav los ntawm nws lub peev xwm rau kev txhawb nqa thiab kev tiv thaiv dej.
** Thermal rwb thaiv tsev (Core Application): **
Qhov no yog qhov tseem ceeb tshaj plaws thiab feem ntau daim ntawv thov sau npe rau nruj polyurethane ua npuas ncauj, peev ntawm nws cov thermal conductivity tsawg heev (kwv yees li 0.017–0.033 W / m·K).
** Cov Khoom Siv Hluav Taws Xob thiab Cov Khaub Ncaws Txias: ** Rigid polyurethane ua npuas ncauj ua cov txheej txheej rwb thaiv tsev hauv cov tub yees, lub freezers, cov chaw cia txias, cov tsheb thauj tub yees, thiab lub tshuab rhaub dej; qhov sector tam sim no suav rau ib qho ntawm cov khoom siv loj tshaj plaws.
**Industrial and Building Insulation:** Nws yog siv rau insulating cua sov pipelines thiab cia tso tsheb hlau luam, raws li zoo raws li rau integrated rwb thaiv tsev thiab waterproofing systems ntawm lub tsev sab nrauv phab ntsa thiab ru tsev. Nws cov thermal kev ua tau zoo tshaj qhov uas feem ntau siv polystyrene boards (EPS / XPS), uas ua rau nws muaj peev xwm loj hlob nyob rau hauv kev loj hlob ntawm lub zog- siv tau zoo.
** Cov Khoom Siv Khoom Siv (High-Daim ntawv thov ceev):**
Siab-qhov ceev (300–700 kg/m³) rigid polyurethane ua npuas ncauj- feem ntau hu ua "imitation wood"- tuaj yeem ua haujlwm raws li cov khoom siv.
**Wood Replacement:** Characterized by high strength, excellent toughness, and a dense surface skin, it is suitable for manufacturing high-end furniture, decorative moldings, picture frames, and similar items, while also offering high production efficiency.
**Kev Thauj Mus Los:** Nws yog siv rau hauv kev tsim cov khoom siv sab hauv rau tsheb -xws li headliners thiab dashboards - qhov twg nws ua haujlwm ob qho tib si ua tus muab tub lim thiab tus neeg sawv cev txhawb nqa.
Lwm Cov Kev Siv Tshwj Xeeb:
Potting and Gap Filling: Leveraging nws flowability thiab adhesive zog thaum lub sij hawm foaming txheej txheem, nws yog siv los sau qhov khoob -xws li cov nyob rau hauv lub qhov rooj thiab qhov rais thav duab los yog cable conduits - pab rau sealing, waterproof, thiab ruaj ntseg cheeb tsam.
Kev Siv Tshwj Xeeb: Nws kuj tseem tuaj yeem siv rau hauv kev ua liaj ua teb toj roob hauv pes, tsim cov qauv kev tshaj tawm, thiab txawm tias muab cov rwb thaiv tsev thermal thiab Frost tiv thaiv cov ntoo nyob rau sab qaum teb.
