1. Indima yezinto zokugcwalisa
Yongeza izihluzi ezifana ne-calcium carbonate, udongwe, i-aluminium hydroxide, iiflakes zeglasi, i-glass microbeads, kunye ne-lithopone kwi-polyester resin kwaye uzisasaze ukuze zenze umxube we-resin.Umsebenzi wayo umi ngolu hlobo lulandelayo:
(1) Ukunciphisa iindleko zezinto ze-FRP (ezifana ne-calcium carbonate kunye nodongwe);
(2) Ukunciphisa izinga lokunciphisa ukunyanga ukukhusela ukuqhekeka kunye nokuguqulwa okubangelwa yi-shrinkage (njenge-calcium carbonate, i-quartz powder, i-glass microspheres, njl.);
(3) Ukuphucula i-resin viscosity ngexesha lokubumba kwaye uthintele ukuvuza kwe-resin.Nangona kunjalo, kufuneka kuqatshelwe ukuba ukunyuka okugqithisileyo kwe-viscosity ngamanye amaxesha kunokuba yinto engalunganga;
(4) Ukungafihli kweemveliso ezenziweyo (ezifana ne-calcium carbonate kunye nodongwe);
(5) Ukwenziwa mhlophe kweemveliso ezenziweyo (ezifana ne-barium sulfate kunye ne-lithopone);
(6) Ukuphucula ukuxhathisa kwe-corrosion yeemveliso ezenziweyo (mica, amaphepha eglasi, njl.);
(7) Ukuphucula ukuxhathisa kwedangatye kwiimveliso ezenziweyo (i-aluminium hydroxide, i-antimony trioxide, iparafini enechlorine);
(8) Ukuphucula ukuqina kunye nokuqina kweemveliso ezenziweyo (ezifana ne-calcium carbonate, i-glass microspheres, njl.);
(9) Ukuphucula amandla eemveliso ezenziweyo (iglasi yomgubo, i-potassium titanate fibers, njl.);
(10) Ukuphucula i-lightweight kunye ne-insulation properties yeemveliso ezibunjiweyo (ii-microspheres ezahlukeneyo);
(11) Ukubonelela okanye ukwandisa i-thixotropy yemixube ye-resin (efana ne-ultrafine anhydrous silica, i-glass powder, njl.).
Ingabonwa ukuba injongo yokongeza iifayili kwii-resin zihlukeneyo, ngoko kubalulekile ukukhetha iifayili ezifanelekileyo ngokweenjongo ezahlukeneyo zokusebenzisa ngokupheleleyo indima yokuzalisa.
2. Izilumkiso zokukhethwa kunye nokusetyenziswa kwezihluzi
Kukho iintlobo ezahlukeneyo zokuzalisa.Ngoko ke, kuyimfuneko ukukhetha uphawu olufanelekileyo lokuzalisa kunye nebakala ngenjongo yokusetyenziswa, ehamba ngaphandle kokuthetha.Izilumkiso ngokubanzi xa ukhetha izigcwalisi azikhethi kuphela iintlobo ngeendleko ezimiselweyo kunye nokusebenza, kodwa kunye nokunikela ingqalelo kula manqaku alandelayo:
(1) Ubungakanani bentlaka efunxayo kufuneka bube ngcathu.Ubungakanani be-resin efunyenweyo inempembelelo ebalulekileyo kwi-viscosity ye-resin mixes.
(2) I-viscosity yomxube we-resin kufuneka ifaneleke kumsebenzi wokubumba.Uhlengahlengiso oluninzi kwi-viscosity yemixube ye-resin lunokwenziwa ngokuhlanjululwa nge-styrene, kodwa ukongeza iifayili ezininzi kunye nokuhlanjululwa nge-styrene kuya kukhokelela ekunciphiseni ukusebenza kwe-FRP.I-viscosity yemixube ye-resin ngamanye amaxesha ichaphazeleka kakhulu yimali yokuxuba, iimeko zokuxuba, okanye ukongezwa kwe-filler surface modifiers.
(3) Iimpawu zokuphilisa umxube we-resin kufuneka zilungele iimeko zokubumba.Iimpawu zokuphilisa zemixube ye-resin ngamanye amaxesha ziphenjelelwa yi-filler ngokwayo okanye i-adsorbed okanye umswakama odibeneyo kunye nezinto zangaphandle kwi-filler.
(4) Umxube we-resin kufuneka uhlale uzinzile ixesha elithile.Kwimeko yokumisa kunye nokwahlulwa kwezizalisi ngenxa yokuma ngxi, ngamanye amaxesha kunokuthintelwa ngokunika i-resin nge-thixotropy.Ngamanye amaxesha, indlela yokuphepha ukuvuselela i-static kunye nokuqhubekayo komatshini ikwasetyenziselwa ukuthintela ukuhlaliswa kweefayili, kodwa kule meko, kuyimfuneko ukuqwalasela ukuthintela ukuhlaliswa kunye nokuqokelela kweefayili kumbhobho ukusuka kwisitya esine-mixer ukuya ekwenzeni. indawo.Xa izigcwalisi ezithile ze-microbead ziqhelene nokwahlula phezulu, kuyafuneka ukuba uqinise ibakala kwakhona.
(5) I-permeability yomxube we-resin kufuneka ifaneleke kwinqanaba lobugcisa bomqhubi.Ukongezwa kwezihluzi ngokubanzi kunciphisa ukucaca komxube we-resin kwaye kunciphisa i-ductility ye-resin ngexesha lokubeka.Ke ngoko, ukumiliselwa, ukwenziwa kogwebu, kunye nokugwetywa ngexesha lokubumba kuye kwaba nzima.Ezi zinto kufuneka ziqwalaselwe ukugqiba umlinganiselo womxube we-resin.
(6) Ingqalelo kufuneka ihlawulwe kubunzima obuthile bomxube we-resin.Xa usebenzisa izihluzi njengezinto ezongezelelekileyo zokunciphisa iindleko zezinto eziphathekayo, ubunzima obuthile bomxube we-resin buyanda xa kuthelekiswa ne-resin, ngamanye amaxesha alihlangani nexabiso elilindelekileyo lokunciphisa iindleko ze-intuitively.
(7) Isiphumo sokuguqulwa komphezulu weefayili kufuneka sihlolwe.I-filler surface modifiers iyasebenza ekunciphiseni i-viscosity yemixube ye-resin, kwaye izilungisi ezahlukeneyo zomphezulu ngamanye amaxesha zinokuphucula amandla omatshini ukongeza ukuxhathisa kwamanzi, ukuxhathisa imozulu, kunye nokuxhathisa imichiza.Kukho neentlobo zokugcwalisa eziye zafumana unyango olungaphezulu, kwaye ezinye zisebenzisa oko kubizwa ngokuba "yindlela yokuxuba yonke" ukuguqula umphezulu wezigcwalisi.Oko kukuthi, xa uxuba imixube ye-resin, iifayili kunye nezilungisi zongezwa kunye ne-resin, ngamanye amaxesha umphumo ulungile kakhulu.
(8) Ukukhupha amagwebu kumxube wentlaka kufuneka kuqhutywe ngokucokisekileyo.Iifayili zihlala zisetyenziswa ngendlela yepowder encinci kunye namaqhekeza, kunye nendawo enkulu kakhulu yendawo ethile.Kwangaxeshanye, kukho iindawo ezininzi apho iipowder ezincinci kunye namasuntswana adibanayo.Ukuze usasaze ezi zigcwalisi kwi-resin, i-resin idinga ukuqhutyelwa ngokukrakra, kwaye umoya utsalwe kumxube.Ukongeza, umoya uphinde utsalwe kumthamo omkhulu wezihluzi.Ngenxa yoko, isixa esingenakucingelwa somoya sixutywe kumxube we-resin olungiselelwe, kwaye kulo mbuso, i-FRP efunyenwe ngokuyinikezela ngokubumba ilungele ukuvelisa ama-bubbles kunye ne-voids, ngamanye amaxesha ayiphumeleli ukuphumeza umsebenzi olindelekileyo.Xa kungenakwenzeka ukukhupha amagwebu ngokupheleleyo ngokuma ngxi emva kokuxuba, ukuhluzwa kwengxowa yesilika okanye ukunciphisa uxinzelelo kungasetyenziselwa ukususa amaqamza.
Ukongeza kula manqaku angentla, amanyathelo okuthintela uthuli kufuneka kwakhona athathwe kwindawo yokusebenza xa usebenzisa iifayili.Izinto ezifana ne-ultrafine particulate silica eyenziwe nge-silica yamahhala, i-alumina, umhlaba we-diatomaceous, amatye anqabileyo, njl.Kukho nemimiselo ekugxininiseni okulawulwayo kweepowder ezahlukeneyo ezincinci kwi-atmosphere.Izixhobo zokukhuphela zasekhaya kufuneka zifakelwe kwaye izixhobo zokukhusela abasebenzi kufuneka zisetyenziswe ngokungqongqo xa kusingathwa ezo zigcwalisi ezinomgubo.
