Polyurethane Log 16 Nti

Polyurethane Log 16 Nti los ntawm Yantai Zhengyuan Polyurethane Co., Ltd. Raws li tus neeg yuav khoom kos duab ntawm cov profiles thiab kev tsim cov ntaub ntawv, peb tuaj yeem hloov kho Polyurethane Log 16 Inch hauv cov duab tshwj xeeb, qhov loj me, xim thiab durometer.

Kev ceev faj rau Polyurethane Log 16 Nti siv
① Tsis txhob siv hauv qhov chaw ntub dej lossis hauv dej. Qhov no yuav ua rau hydrolysis ntawm polyurethane.
② Polyurethane hydrolysis yam ntxwv: Yog tias polyurethane siv tsis tu ncua nyob rau hauv ib puag ncig uas muaj dej los yog ya raws ntev, nws yuav raug hydrolysis thiab deteriorate. Nws raug nquahu kom kuaj xyuas lub tsev khaws khoom thiab kev siv ib puag ncig hauv thaj chaw uas muaj av noo siab
Kev tswj qhov kub thiab av noo kom ntev kev pab cuam lub neej ntawm cov khoom.
③ Lub xeev ntawm cov khoom hloov tom qab hydrolysis, thiab qhov chaw ntawm polyurethane ua ib qho nplaum nplaum. Maj mam nias tus ntsia hlau yuav tawm irreversible nti, thiab lub hardness ntawm polyurethane yuav txo. Cov polyurethane yuav qhuav thiab tawg, yooj yim disintegrating rau hauv hmoov
④ Qhov loj ntawm polyurethane hloov nrog qhov ntsuas kub ib puag ncig, tab sis qhov kev hloov pauv tsis tseem ceeb, thiab nws tuaj yeem rov qab los rau nws qhov qub qub tom qab tso rau hauv chav sov li ob peb teev.
⑤ Lub hardness kam rau ua feem ntau nyob ib ncig ntawm ntug dej hiav txwv ± 5 degree, uas yog tus nqi ib txwm.
