Polyether Polyols Rau Polyurethanes

Polyether polyols(PPG)yog ib chav kawm ntawm macromolecular compounds tsim los ntawm alkali-catalyzed polymerization ntawm ethylene oxide, propylene oxide, los yog lwm yam epoxides. Lawv feem ntau tsis muaj xim rau cov kua daj lossis cov khoom khib nyiab nrog ntau pawg hydroxyl (-OH) ua haujlwm. Nyob ntawm qhov hnyav molecular thiab kev ua haujlwm qib (hydroxyl tooj), polyether polyols tuaj yeem nthuav tawm cov khoom sib txawv ntawm lub cev, xws li viscosity, hardness, thiab lwm yam. Polyether polyols muaj qhov zoo solubility thiab reactivity.

1. Polyurethane ua npuas ncauj:

Mos ua npuas ncauj: Siv rau cov rooj tog zaum (xws li rooj zaum, rooj zaum), txaj, rooj zaum hauv tsheb thiab lwm yam ntaub ntawv mos, nyiam ua npuas ncauj.

 

2, Ua npuas ncauj tawv: rau lub tsev rwb thaiv tsev, cov khoom siv tub yees (xws li lub tub yees, lub tub yees) txheej txheej rwb thaiv tsev, nrog rau cov khoom ntim thiab lwm yam kev siv uas yuav tsum tau ua kom nruj thiab ua haujlwm zoo rwb thaiv tsev.

 

3. Elastomer:

Kev tsim cov khoom siv nrog cov elasticity siab thiab hnav tsis kam, xws li cov khau khau, lub log, conveyor siv, thiab lwm yam.

 

4, Xim thiab sealant:

Siv los tsim cov txheej txheem kev ua haujlwm siab thiab cov sealants uas muab kev tiv thaiv corrosion thiab dej tsis kam.

 

5. Adhesive:

Siv los ua cov khoom siv rau cov nplaum rau hauv daim ntawv thov uas yuav tsum tau muaj zog thiab ruaj khov.

 

6, Elastic fiber ntau:

Rau zus tau tej cov elastic fibers thiab fabrics.

 

7. Cov khoom siv sib xyaw:

Siv los ua ib feem ntawm cov khoom siv txhawb zog hauv qee qhov sib xyaw.

 

1.Dab tsi ntawm kev ntim khoom koj feem ntau muab?
Feem ntau hauv 200kg nruas, peb tuaj yeem muab rau koj nrog IBC nruas thiab ISOtank ntim raws li koj xav tau

2.Yog cov khoom txaus ntshai?
Cov khoom no yog cov khoom tsis muaj kev phom sij, xa tawm raws li cov khoom lag luam zoo tib yam, peb tuaj yeem muab koj nrog MSDS thiab cov ntaub ntawv txheeb xyuas kev thauj mus los ua ntej xa khoom.

3. Dab tsi yog qhov chaw cia khoom rau polyether polyols?

Polyether polyols yuav tsum muab cia rau hauv qhov chaw qhuav, txias, deb ntawm tshav ntuj ncaj qha. Cov thawv ntim khoom yuav tsum tau muab kaw kom tsis txhob ya raws los ntawm kev nkag mus, vim tias noo noo tuaj yeem ua rau cov polyols tuaj yeem tshwm sim.
