Yini impahla eyi-fr4 epoxy glass fiber board

Yini impahla eyi-fr4 epoxy glass fiber board? Yini impahla epoxy resin board? Kungcono ukusebenzisa izinto ezilandelayo:

A. I-epoxy resin, ebhekisa egameni elijwayelekile lama-polymers aqukethe amaqembu epoxy. Ilungele ikakhulukazi imidiya enezinto ezingonakalisi kangako. Inokumelana okuvelele kwe-alikhali futhi ingamelana nokugqwala kwama-acid ajwayelekile (ngaphandle kwe-hydrofluoric acid). Isidingo sama-epoxy resins emakethe yokugqwala sincishiswe kakhulu. Isizathu esiyinhloko ukuthi izinhlayiya ze-polyester ezingasetshenzisiwe ezinhlakeni zokumelana nokugqwala zikhule ngokushesha futhi kunezinhlobo eziningi. Imakethe yasekhaya inesiqalo sekwephuzile sezinhlayiya ze-polyester ezingasuthisiwe, ngakho-ke izinhlaka ze-epoxy Kusengenye yezinhlobo ezinkulu ze-resin emkhakheni we-anti-corrosion. Izici eziyinhloko ze-epoxy resin zingamandla amakhulu okuhlanganisa, ukuncipha okuphansi, umkhiqizo omncane we-brittleness, nentengo ephezulu. Ukushisa okusetshenzisiwe kwe-resin ephulukisiwe ekamelweni lokushisa akudluli kuma-80 ° C;

B. Nguyena ophulukisa i-fr4 epoxy glass fiber board) i-epoxy resin. Kunezinhlobo eziningi zama-amine, ama-acid anhydrides, ama-resin compounds njalonjalo. Phakathi kwazo, amakhemikhali e-amine asetshenziswa kakhulu. Zingahlukaniswa ngama-amine anamafutha, amine anamakha nama-amino aguquliwe. Izinhlobo eziningana zama-amine, njenge-ethylenediamine, i-m-phenylenediamine, i-xylylenediamine, i-polyamide, i-diethylenetriamine namanye ama-compounds, anobuthi futhi anuka phu, ngakho-ke asetshenziswa kancane kancane ngama-ejenti amasha aphilisayo angenabuthi futhi anobuthi (njenge: T31 , 590, C20, njll.) Esikhundleni salokho, lolu hlobo lwe-agent elaphayo lungelashwa ngisho nangaphansi kwamanzi kusendlalelo esimanzi, ngakho-ke abantu banaka kakhulu futhi badumisa;

C. Yi-fr4 epoxy glass fiberboard diluent. I-epoxy resin ivame ukuhlanjululwa ngezithako ezingasebenzi ezifana ne-ethanol, i-acetone, i-benzene, i-toluene, i-xylene, njll. Izithako ezimbili ezingasebenzi zingaxutshwa futhi zisetshenziswe, kwesinye isikhathi ukunciphisa ukuphulukisa izithako ezisebenzayo ezinjenge-propylene oxide butyl ether, propylene oxide i-phenyl ether, i-polyglycidyl ether, njll. nayo isetshenziselwa ukuncipha komkhiqizo ophelile, ukunciphisa ama-pores nemifantu;

D.I-plasticizer ne-ejensi yokuqinisa ye-fr4 epoxy glass fiberboard. I-epoxy resin elula iyabhidlika kakhulu ngemuva kokuphulukiswa, futhi inamandla omthelela omubi, amandla okugoba nokumelana nokushisa. Ama-plasticizers kanye nama-tougheners ajwayele ukusetshenziselwa ukwenza i-Resin inyuse i-plasticity, ithuthukise ukuqina, inyuse amandla okugoba kanye nokuqina kokuqina;

E. It is a filler, powder, fine aggregate, aggregate coarse, kanye nama-glass flakes ngokuhlanganyela abizwa ngokuthi ama-filler. Ukungeza okugcwalisa okufanele kunganciphisa izindleko zomkhiqizo futhi kuthuthukise ukusebenza kwawo. Inani lokugcwalisa ku-glue ngokuvamile liyinhlaka Inani elingu-20-40% (isisindo), inani lingaba ngaphezulu lapho kulungiswa i-putty, ngokuvamile ingaba izikhathi eziphindwe kabili kuya kwezine inani le-resin, izimpushana ezisetshenziswa kakhulu ziyimpuphu ye-quartz, i-porcelain powder, ngaphezu kwe-graphite powder, i-powder eluhlaza eluhlaza, i-talcum powder, i-mica powder, njll.
