Kodi ukadaulo wa zokutira kunja kwa chitoliro cha epoxy glass fiber ndi chiyani?

1) Chiŵerengero cha mphamvu ndi modulus ndichokwera. Mphamvu yeniyeni ndi modulus yeniyeni imatanthawuza mphamvu ya zinthu ndi chiŵerengero cha modulus ndi kachulukidwe. Kukwera kwamphamvu kwapadera, kumachepetsa kulemera kwa gawolo. Kukwera kwa modulus yeniyeni, kumapangitsa kuti gawolo likhale lolimba. Choncho, kufunikira kwa ntchito yothamanga kwambiri ya zigawo zamapangidwe kapena kuchepetsa kulemera kwa mayendedwe ndizofunika kwambiri.

2) Kulumikizana pakati pa CHIKWANGWANI ndi masanjidwewo muzinthu zophatikizika zama fiber kumatha kuletsa kufalikira kwa ming’alu ya kutopa, ndipo katundu wakunja amanyamulidwa ndi ulusi wolimbikitsidwa. Kuchepetsa mphamvu ya kutopa kwazinthu zambiri zachitsulo ndi 30% ~ 50% ya mphamvu zake zolimba, pomwe mphamvu ya kutopa yazinthu zophatikizika ndi 60% ~ 80%

3) Kuonjezera kachulukidwe kakang’ono ka carbon fiber ku thermoplastics kumatha kusintha kwambiri kukana kwake, ndipo nthawi yake yowonjezera imatha kuwirikiza kangapo. Mwachitsanzo, mpweya CHIKWANGWANI analimbitsa PVC ndi 3.8 nthawi yake, PTFE ndi 3 nthawi zake, polypropylene ndi 2.5 nthawi yake, polyamide ndi 1.2 nthawi yake, ndi poliyesitala ndi 2 nthawi yake. Nthawi. Pogwiritsa ntchito zipangizo zoyenera za pulasitiki ndi zitsulo zachitsulo, zingagwiritsidwe ntchito ngati zinthu zosavala, monga zonyamula katundu. The atatu wosanjikiza zakuthupi ndi polytetrafluoroethylene (kapena polyoxymethylene) monga pamwamba wosanjikiza ndi porous mkuwa ndi mbale zitsulo monga wosanjikiza wamkati akhoza kukhala zipangizo zabwino kwambiri mayendedwe kutsetsereka.

4) Kukhazikika kwabwino kwamankhwala. Mapulasitiki a phenolic olimbikitsidwa ndi fiber amatha kugwiritsidwa ntchito muzofalitsa za acidic zomwe zimakhala ndi ayoni a kloride kwa nthawi yayitali. Pogwiritsa ntchito mapulasitiki opangidwa ndi galasi, mapaipi amadzimadzi, mapampu, ma valve ndi zotengera zomwe zimagonjetsedwa ndi asidi amphamvu, mchere, esters ndi zosungunulira zina. Ngati ulusi wosamva za alkaliwo wasakanizidwa ndi pulasitiki, utha kugwiritsidwanso ntchito munjira yamphamvu yamchere. Ulusi wosamva alkali ukhoza kugwiritsidwa ntchito m’malo mwa zitsulo ndi simenti.

5) High kutentha ablation kukana. Kupatula kutsika kosungunuka (900 ° C) ndi malo otsika osungunuka (700 ° C) zipangizo zophatikizika, nthawi zambiri zimalimbikitsidwa ndi zitsulo zachitsulo. Mwachitsanzo, kaboni fiber kapena boron fiber ikagwiritsidwa ntchito ngati kulimbikitsa, mphamvu ndi modulus pa 400 ° C. zimatha kusungidwa kutentha kwa chipinda. Mpweya wofanana wa carbon fiber wolimbitsa nickel sikuti umachepetsa kachulukidwe, komanso uli ndi ntchito yotentha kwambiri. FRP imakhala ndi matenthedwe otsika kwambiri komanso kutentha kwambiri, kotero imatha kugwiritsidwa ntchito ngati anti-ablation material.

6) Ukadaulo wabwino ndikukonzekera. Ndi kusintha mawonekedwe, masanjidwe ndi zili kulimbikitsa chuma, mphamvu ndi kusasunthika kwa zigawo zikuluzikulu akhoza anakumana, ndi zipangizo ndi zigawo zikuluzikulu akhoza kupangidwa nthawi imodzi, potero kuchepetsa chiwerengero cha zigawo, fasteners ndi mafupa, ndi bwino kwambiri. mphamvu ya ziwalo. Kugwiritsa ntchito zinthu.
