Yiziphi izici zokusetshenziswa kwepayipi le-epoxy glass fiber?
Yiziphi izici zokusetshenziswa kwepayipi le-epoxy glass fiber?
1. Amafomu ahlukahlukene. Izinhlaka ezahlukahlukene, ama-ejenti aphulukisayo, kanye nezinhlelo zokuguqula cishe zingazivumelanisa nezidingo zezinhlelo zokusebenza ezahlukahlukene kwifomu, futhi ububanzi bungaba kusuka ku-viscosity ephansi kakhulu kuye kokuqina okuphezulu kokuncibilika.
2. Ukwelapha okulula. Khetha ama-ejenti ahlukahlukene aphulukisayo, uhlelo lwe-epoxy resin cishe lungalapheka ebangeni lokushisa elingu-0 ~ 180 ℃.
3. Ukunamathela okuqinile. Ukuba khona kwe-polar hydroxyl kanye nebhondi ye-ether [1] etholakala ochungechungeni lwemolekyuli ye-epoxy resin kuyenza ibe nokunamathela okuphezulu ezintweni ezihlukahlukene. Ukuncipha kwe-epoxy resin kuphansi lapho uphulukisa, futhi ukucindezeleka kwangaphakathi okukhiqizwa kuncane, okusiza futhi ukuthuthukisa amandla okunamathela.
4. Ukuncipha okuphansi. Ukusabela phakathi kwe-epoxy resin kanye ne-ejenti elaphayo esetshenziswayo kwenziwa ngokusabela kokwengeza okuqondile noma ukusabela kwe-polymerization yokuvula indandatho yamaqembu e-epoxy ku-molecule ye-resin, futhi awekho amanzi noma eminye imikhiqizo eshintshashintshayo ekhishwayo. Uma kuqhathaniswa nezinhlayiya ze-polyester ezingasetshenzisiwe kanye nama-phenolic resins, abonisa ukuncipha okuphansi kakhulu (ngaphansi kuka-2%) ngesikhathi sokwelashwa.
5. Izakhiwo zemishini. I-epoxy resin system ephulukisiwe inezakhiwo ezinhle kakhulu zomshini.
