Mugadziri Mutengo Wakanaka Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1

tsananguro pfupi:

PMDPTA ifuro/gel balance catalyst ine hwema hushoma, inogona kushandiswa mufuro rakapfava repolyurethane, mabubble akaoma epolyurethane uye zvinonamatira zvekuputira. PMDPTA inonyanya kushandiswa mufuro reHR remhando yechando. PMDPTA inonzi five-base di-propyleneramine, iyo ine mashandisirwo akasiyana-siyana mufuro rakapfava nerakaoma. PMDPTA inogona kupa mhinduro yekutanga yakaringana uye mhinduro yegel, uye kuwedzera nguva yekupindura kwefuro uye mhinduro yegel. Iyi catalyst haingogone kushandiswa yoga chete, asiwo inogovaniswa nedzimwe catalysts nezvimwe zvinoshandiswa. PMDPTA inogona kunyungudutswa mupolyether polyol.

Inonyungudika nyore nyore muzvinhu zvakawanda zvinonyungudutsa. Foam negel reaction balance. Zvakanakira zvinoshandiswa mu soft block foam, izvo zvinogona kudzivirira kutsemuka uye pinhole yefuro, iyo ine simba rakanaka rekusimudza. Kuvandudza kugona kwayo kugadzikiswa, kushivirira uye kushanda kwayo pamusoro pemvura. Kuvandudza buri repamusoro re soft foam plastic.

Hunhu hwehunhu: pokufashaira: 102 ° C / 1mmHg, density: 0,83 g / cm3, refractive index: 1.4450 kusvika 1.4480, flash point: 92 ° C, acidity coefficient (PKA): 9.88 ± 0.28 (Kufanotaura). Inonyanya kushandiswa kune alkaline melting phenols, uye inoshandiswawo kune inter-phenylphenols, nezvimwewo, uye inowanzoshandiswa se catalysts mu esterization uye dehydration reactions; dhayi intermediate

Mashandisirwo ePMDPTA

Pentamethyldipropylenetriamine chinhu chinobatsira pakuenzanisa furo/gel, chinogona kushandiswa pakugadzira furo rakapfava repolyether polyurethane, mabubble akaomarara epolyurethane, macoatings, manamati, nezvimwewo, zvinonyanya kukodzera kushandiswa pakushandisa Yu Cold Model HR Bubble. Furo racho rakavhurika zvakanaka uye rinoshandiswa muMaxfoam foam process, iro rine mashandiro akanaka kwazvo.
