Uyazazi izici ezimbalwa zepayipi le-epoxy glass fiber?

Ishubhu le-epoxy glass fiber lenziwe ngendwangu yengilazi engenawo ugesi ye-alkali efakwe nge-epoxy resin, ibhakwe, futhi icutshungulwe ngokucindezela okushisayo ekubunjeni okwakhayo. Ingxenye yesiphambano iyinduku eyindilinga. Induku yendwangu yengilazi inezakhiwo eziphezulu zemishini. Ingaphezulu le-epoxy glass fiber tube kufanele libe bushelelezi ngaphandle kwamabhamuza, amabala kawoyela nokungcola. Umbala ongalingani, ukuhlikihlwa kancane, njll. konke kungaphakathi kwebanga elivumelekile. Amapayipi e-epoxy fiberglass asetshenziselwa izingxenye zesakhiwo sokufakelwa kwemishini kagesi, izimo zemvelo ezinomswakama kanye nowoyela we-transformer.

Izici zamapayipi e-epoxy glass fibre zibanzi, futhi ububanzi bokusebenza bubanzi, futhi amafomu ahlukene. I-resin, i-ejenti elaphayo, kanye nesistimu yokuguqula ingacishe ivumelane nezidingo zezinhlelo zokusebenza ezihlukahlukene efomini, futhi ububanzi bungaba ukusuka ku-viscosity ephansi kakhulu ukuya kokuqinile kwendawo yokuncibilika. Okwesibili, ukulungiswa kulula kakhulu. Khetha izinhlobonhlobo zama-ejenti okwelapha ahlukene, futhi uhlelo lwe-epoxy resin lungelapheka ezingeni lokushisa elingu-0-180°C.

Into eyodwa okufanele ngiyibalule ukuthi inokunamathela okuqinile. Kunamaqembu e-polar hydroxyl namabhondi e-ether ochungechungeni lwamangqamuzana e-epoxy resin, elenza libe nokunamathela okuphezulu ezintweni ezihlukahlukene. Ukuncipha kwe-epoxy resin kuphansi lapho uphulukisa, futhi ukucindezeleka kwangaphakathi okukhiqizwa kuncane, okusiza futhi ukuthuthukisa amandla okunamathela. Iphinde ibe nokushwabana okuphansi. Ukusabela phakathi kwe-epoxy resin kanye ne-ejenti elaphayo kwenziwa ngokusabela kokwengeza okuqondile noma ukusabela kwe-polymerization yokuvula indandatho yamaqembu e-epoxy ku-molecule ye-resin, futhi awekho amanzi noma eminye imikhiqizo eguqukayo ekhishwayo. Ngokusho kwedatha efanele, uma kuqhathaniswa ne-polyester resin engasetshenzisiwe kanye ne-phenolic resin, ukuncipha ngesikhathi senqubo yokwelapha kuphansi kakhulu, cishe u-2%. .
