Glass Mat Reinforced Thermorplastic (GMT) imatanthawuza buku, zopulumutsa mphamvu komanso zopepuka zophatikizika zomwe zimagwiritsa ntchito utomoni wa thermoplastic ngati matrix ndi magalasi fiber mat ngati chigoba cholimbitsidwa.Pakali pano ndi zinthu zophatikizika kwambiri padziko lonse lapansi.Kukula kwa zida kumawonedwa ngati chimodzi mwazinthu zatsopano zazaka zana.GMT nthawi zambiri imatha kupanga zinthu zomwe zatsirizidwa pang'ono, kenako ndikuzipanga mwachindunji kukhala zomwe mukufuna.GMT ili ndi mawonekedwe ovuta, kukana kwamphamvu kwambiri, ndipo ndiyosavuta kusonkhanitsa ndikukonzanso.Imatamandidwa chifukwa cha mphamvu zake komanso kupepuka kwake, ndikupangitsa kuti ikhale gawo loyenera lopanga m'malo mwachitsulo ndikuchepetsa misa.
1. Ubwino wa zida za GMT
1. Mphamvu zenizeni zenizeni: Mphamvu za GMT ndizofanana ndi zopangidwa ndi polyester FRP zoyikidwa pamanja.Kuchulukana kwake ndi 1.01-1.19g/cm, yomwe ndi yaying'ono kuposa thermosetting FRP (1.8-2.0g/cm), kotero ili ndi mphamvu zapadera..
2. Zopepuka komanso zopulumutsa mphamvu: Kulemera kwa chitseko cha galimoto chopangidwa ndi zinthu za GMT kumatha kuchepetsedwa kuchokera ku 26Kg mpaka 15Kg, ndipo makulidwe a msana amatha kuchepetsedwa, kotero kuti malo a galimoto awonjezeka.Kugwiritsa ntchito mphamvu ndi 60-80% yokha ya zinthu zachitsulo ndi 35 zazinthu za aluminiyamu.-50%.
3. Poyerekeza ndi thermosetting SMC (mapepala opangira mapepala), zinthu za GMT zili ndi ubwino wafupikitsa kuumba, kukhudzidwa kwabwino, kubwezeretsedwanso ndi nthawi yayitali yosungirako.
4. Kuchita kwamphamvu: Kutha kwa GMT kuyamwa mphamvu ndi kuwirikiza 2.5-3 kuposa kwa SMC.Pansi pa zomwe zimachitika, ziboda kapena ming'alu zimawonekera mu SMC, chitsulo ndi aluminiyamu, koma GMT ndi yotetezeka.
5. Kukhazikika kwakukulu: GMT ili ndi nsalu ya GF, yomwe imatha kusunga mawonekedwe ake ngakhale pali mphamvu ya 10mph.
2. Kugwiritsa ntchito zida za GMT m'munda wamagalimoto
Tsamba la GMT lili ndi mphamvu zenizeni zenizeni, limatha kupanga magawo opepuka, ndipo lili ndi ufulu wopanga, kuyamwa kwamphamvu kwamphamvu kugundana, komanso magwiridwe antchito abwino.Lakhala likugwiritsidwa ntchito kwambiri mumakampani amagalimoto kunja kwa 1990s.Pomwe zofunikira pazachuma chamafuta, kubwezeretsedwanso komanso kusavuta kukonza zikupitilira kukula, msika wa zida za GMT zomwe zimagwiritsidwa ntchito pamakampani amagalimoto ukupitilira kukula.Pakadali pano, zida za GMT zimagwiritsidwa ntchito kwambiri pamafakitale amagalimoto, makamaka kuphatikiza mafelemu a mipando, mabampu, ma dashboards, ma hoods a injini, mabatire a mabatire, ma pedals, malekezero akutsogolo, pansi, alonda, zitseko zakumbuyo, madenga agalimoto, Mabulaketi akatundu, zowonera dzuwa, zotsalira. matayala ndi zigawo zina.
