Enwere ike ịhụ na ebumnuche nke ịgbakwunye ihe ndochi na resins dị iche iche, n'ihi ya, ọ dị mkpa ịhọrọ ihe ndozi kwesịrị ekwesị dị ka ebumnuche dị iche iche iji jiri ọrụ nke ndị na-emepụta ihe mee ihe n'ụzọ zuru ezu.
2. Akpachara anya maka nhọrọ na iji ihe ndochi
Enwere ụdị nju dị iche iche.Ya mere, ọ dị mkpa ịhọrọ akara ndochi kwesịrị ekwesị na ọkwa maka ebumnuche ojiji, nke na-aga n'ekwughị okwu.Akpachara anya mgbe ị na-ahọrọ fillers abụghị naanị ịhọrọ ụdị dị iche iche nwere ọnụ ahịa na arụmọrụ ekpebiela, kamakwa ịṅa ntị na isi ihe ndị a:
(1) Ọnụ ọgụgụ resin etinyere kwesịrị ịdị oke oke.Ọnụ ọgụgụ nke resin etinyere na-enwe mmetụta dị ukwuu na viscosity nke ngwakọta resin.
(2) The viscosity nke resin ngwakọta kwesịrị ekwesị maka ịkpụzi ọrụ.Enwere ike ime ọtụtụ mgbanwe na viscosity nke ngwakọta resin site na iji styrene na-agbaze, mana ịtinye ọtụtụ ihe na-ejuputa na styrene ga-eduga na mbelata arụmọrụ FRP.A na-emetụta viscosity nke ngwakọta resin mgbe ụfọdụ site na ọnụọgụ agwakọta, ọnọdụ agwakọta, ma ọ bụ mgbakwunye nke ihe ndozi elu.
(3) Njirimara ọgwụgwọ nke ngwakọta resin kwesịrị ịdị mma maka ọnọdụ ịkpụzi.Njirimara ọgwụgwọ nke ngwakọta resin na-enwe mmetụta mgbe ụfọdụ site na ndochi n'onwe ya ma ọ bụ nke adsorbed ma ọ bụ agwakọta mmiri na ihe ndị mba ọzọ na ndochi.
(4) Ngwakọta resin kwesịrị ịnọgidesi ike ruo oge ụfọdụ.N'ihi na onu nke edozi na nkewa nke fillers n'ihi guzoro otu ebe, ọ nwere ike mgbe ụfọdụ na-egbochi site n'inye resin na thixotropy.Mgbe ụfọdụ, a na-ejikwa usoro nke ịzere static na-aga n'ihu n'ibu mkpagharị iji gbochie mmezi nke fillers, ma na nke a, ọ dị mkpa iji tụlee igbochi mmezi na nchịkọta nke fillers na pipeline site na akpa nwere mixer na-akpụ. saịtị.Mgbe ụfọdụ ihe ndochi microbead na-adịkarị mfe nkewa elu, ọ dị mkpa iji megharịa ọkwa ahụ.
(5) The permeability nke ngwakọta resin kwesịrị ekwesị maka ọkwa nka nke onye ọrụ.Mgbakwunye nke ihe nchacha n'ozuzu na-ebelata nghọta nke ngwakọta resin ma na-ebelatakwa ductility nke resin n'oge nhazi.Ya mere, impregnation, defoaming ọrụ, na ikpe n'oge ịkpụzi aghọwo ihe siri ike.Ekwesịrị ịtụle ihe ndị a iji chọpụta oke nke ngwakọta resin.
(6) Ekwesịrị itinye nlebara anya na ike ndọda nke ngwakọta resin.Mgbe ị na-eji ihe ndochi dị ka ihe mgbakwunye iji belata ọnụ ahịa ihe onwunwe, ike ndọda nke ngwakọta resin na-abawanye ma e jiri ya tụnyere resin, mgbe ụfọdụ anaghị ezute uru a tụrụ anya ya nke na-ebelata ọnụ ahịa ihe n'ụzọ dị omimi.
(7) Ekwesịrị inyocha mmetụta mgbanwe elu nke ndị na-ejuputa.Ndị na-eme ihe na-emeju ihe na-arụ ọrụ nke ọma n'ibelata viscosity nke ngwakọta resin, na ndị na-agbanwe elu dị iche iche nwere ike imeziwanye ike ọrụ mgbe ụfọdụ na mgbakwunye na nkwụsị mmiri, nkwụsị ihu igwe, na nguzogide kemịkalụ.E nwekwara ụdị ihe ndochi nke emerela ọgwụgwọ elu, ụfọdụ na-ejikwa ihe a na-akpọ “usoro agwakọta agwakọta niile” na-agbanwe elu igwe.Ya bụ, mgbe ị na-agwakọta ngwakọta resin, a na-agbakwunye ihe ndị na-ejuputa na ndị na-agbanwe agbanwe na resin, mgbe ụfọdụ mmetụta dị mma.
(8) Ekwesịrị ime nke ọma na-emezi ụfụfụ na ngwakọta resin.A na-ejikarị ihe ndị na-emepụta ihe eme ihe n'ụdị micro powders na ụmụ irighiri ihe, nke nwere nnukwu ebe dị elu.N'otu oge ahụ, e nwekwara ọtụtụ akụkụ ebe micro powders na ahụ na-ejikọta ibe ha.Iji chụsasịa ihe ndị a n'ime resin ahụ, resin kwesịrị inwe mkpali siri ike, a na-adọta ikuku n'ime ngwakọta.Tụkwasị na nke ahụ, a na-adọtakwa ikuku n'ime nnukwu olu nke ihe nkpuchi.N'ihi ya, a na-agwakọta ikuku a na-apụghị ichetụ n'echiche n'ime ngwakọta resin a kwadebere, na na steeti a, FRP nwetara site n'inye ya maka ịkpụzi na-adịkarị mfe ịmepụta afụ na oghere, mgbe ụfọdụ na-emezughị ọrụ a tụrụ anya ya.Mgbe ọ na-agaghị ekwe omume ịgbasa ụfụfụ kpamkpam naanị site n'iguzoro ka agwakọtachara, enwere ike iji nzacha akpa silk ma ọ bụ mbelata nrụgide iji wepụ afụ.
Na mgbakwunye na isi ihe ndị dị n'elu, ekwesịrị ịme usoro mgbochi uzuzu na gburugburu ebe a na-arụ ọrụ mgbe ị na-eji ihe ndochi.A na-ekewa ihe ndị dị ka ultrafine particulate silica nke nwere silica efu, alumina, diatomaceous earth, nkume oyi kpọnwụrụ, wdg dị ka Klas I uzuzu, ebe calcium carbonate, iko ntụ ntụ, iko flakes, mica, wdg na-nkewa dị ka Class II ájá.E nwekwara ụkpụrụ na ntinye uche nke micro powders dị iche iche na-achịkwa na gburugburu ebe obibi.A ghaghị ịwụnye ngwaọrụ ndị na-ekpochapụ ihe na mpaghara yana a ga-ejikwa ngwá ọrụ nchebe ọrụ nke ọma mgbe ị na-eji ihe ndị dị otú ahụ na-eme ntụ ntụ.
