Kev ua haujlwm siab polyether polyols PPG5000 muaj ntau dua reactivity, thiab muaj cov yam ntxwv ntawm cov khoom tsis muaj peev xwm hnov qhov ntswg. Ntxiv mus, cov khoom thov kam rau ua yog dav. Nyob rau hauv thaum ntxov thiab nruab nrab theem ntawm foaming, lub foaming tus nqi yog nruab nrab, thiab ib tug ceev ceev gel npaum li cas nyob rau hauv lub tom ntej theem, uas yuav ua tau raws li cov foaming xav tau kev sib txawv ntom thiab siab resilience sponges nyob rau hauv feem ntau ib puag ncig.
Standards thiab kev ua tau zoo
Cov txheej txheem rau siab-resilience sponge ua los ntawm cov active polyether polyols muaj xws li ntsuas xws li ceev, tensile zog, rebound tus nqi, compression deformation thiab durability. Cov qauv no ua kom cov khoom zoo thiab kev ua tau zoo thiab muab kev txhawb nqa zoo dua thiab kev nplij siab. Piv txwv li, qhov ceev yog feem ntau ntawm 30-80kg/m³, thiab tus nqi rov qab yog feem ntau ntawm 50%-90%. Cov ntsuas no ua ke lav qhov kev ua tau zoo ntawm daim txhuam cev high-rebound.
Daim ntawv thov
High-resilience sponge ua los ntawm cov active polyether polyols yog dav siv nyob rau hauv ntau lub teb vim nws cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg, xws li tab sis tsis txwv rau cov txaj mos thiab txaj, lub rooj zaum tsheb, maus taus cushions, rooj zaum cushions, kis las tiv thaiv iav, thiab lwm yam. Cov khoom siv sponge no tau txais tos thiab thov vim nws qhov elasticity siab, siab resilience, kev noj qab haus huv thiab kev tiv thaiv ib puag ncig.
Ntxiv nrog rau nws daim ntawv thov nyob rau hauv lub tsev teb, high-resilience sponge kuj tau lug siv nyob rau hauv lub automotive kev lag luam, cov khoom ua si, kev lag luam khoom ua si, thiab lwm yam. Piv txwv li, nyob rau hauv lub automotive kev lag luam, high-resilience sponge yog siv los ua lub rooj zaum tsheb. , backrests, thiab lwm yam, muab kev nplij siab thiab kev txhawb nqa. Nws zoo poob siab tsis kam, softness, zoo tsim kua muag zog, yooj yim hardness hloov, zoo resilience, zoo elasticity, thiab lwm yam.

KEV TIV THAIV
Flash point yog siab dua 200 degree (qhib khob txoj kev), flammable tab sis tsis tawg. Thaum hluav taws, muab tso nrog
foams, qhuav hmoov, chav los yog dej.
Thaum tuav cov polyols, yuav tsum tau ceev faj kom tsis txhob raug lub qhov muag los yog ntev kev sib cuag nrog
daim tawv nqaij. Yog tias qhov muag pom tshwm sim, yaug nrog dej kom ntau. Yog tias muaj kev sib cuag ntawm daim tawv nqaij, ntxuav qhov chaw raug
kom huv si nrog xab npum thiab dej.
Daim ntawv thov
Khaws hauv cov nruas tshiab, 210KGS / nruas.
Nws yog me ntsis hygroscopic thiab tuaj yeem nqus dej. Cov thawv ntim khoom yuav tsum tau muab kaw thiab tiv thaiv los ntawm kev sib kis ntawm cov dej noo thiab cov khoom txawv teb chaws.
Lub txee lub neej yog 12 lub hlis. Tom qab ntawd, kev sim ua ntej yuav tsum tau ua ua ntej siv.
