Peroxide Curable FKM Raw Polymer
Zitsanzo za Stock ndi Zaulere & Zilipo
Peroxide kuchiza FKM ndi terpolymer wa hexafluoropropylene, vinylidene fluoride ndi tetrafluoroethylene. Ili ndi zinthu pansipa poyerekeza ndi chikhalidwe cha bisphenol chochiritsikafluoroelastomer.
* Kuthamanga kwabwino kwambiri komanso kutulutsa nkhungu.
* Mphamvu zolimba kwambiri komanso magwiridwe antchito oletsa kulera.
* Njira yochiritsira mwachangu.
* Kuchita bwino kosagwirizana ndi wothandizira.
* Makhalidwe abwino ophatikizika.

Kodi kusankha fluoroelatomer?
FKM Copolymer vs FKM Terpolymer
Copolymer: 66% fluorine zili, ntchito wamba, kukana mafuta, mafuta, kutentha, mankhwala. Ntchito wamba ndi o mphete, zosindikizira mafuta, packers, gaskets, etc.
Terpolymer: fluorine yapamwamba kwambiri kuposa copolymer 68% ya fluorine. Kukana bwino kwa mafuta, mafuta, kutentha, mankhwala, omwe amagwiritsidwa ntchito m'malo ovuta omwe copolymer sangathe kukwaniritsa zofunikira.
Bisphenol yochiritsika FPM vs Peroxide yochiritsika FPM
Bisphenol curable FPM ili ndi ma compression otsika, zopereka zomwe zimagwiritsidwa ntchito ngati mphete, ma shaft seals, piston seals. Mtengo ndi wabwino.
Peroxide curable FPM imakhala yabwino kukanazosungunulira polar, nthunzi, zidulo, mankhwala.Mtengo ndi wokwera kwambiri. Nthawi zambiri amagwiritsidwa ntchito pazida zovala, ma hoses amafuta a extrusion.
Kusungirako
Viton precompound iyenera kusungidwa pamalo ozizira, owuma komanso mpweya wabwino. Nthawi ya alumali ndi miyezi 24 kuyambira tsiku lopanga.
Phukusi
1. Kuti tipewe zosakaniza zimamatirana, timagwiritsa ntchito filimu ya PE pakati pa gawo lililonse la mankhwala a FKM.
2. Aliyense 5kgs mu mandala PE thumba.
3. Aliyense 20kgs/25kgs mu katoni.
4. 500kgs pa mphasa, ndi n'kupanga kulimbitsa.
