1. Basa rekuzadza zvinhu
Wedzera mafirita akadai se calcium carbonate, ivhu, aluminium hydroxide, girazi flakes, girazi microbeads, uye lithopone kune polyester resin uye uaparadzira kugadzira resin musanganiswa.Basa rayo rinotevera:
(1) Deredza mari yezvinhu zveFRP (zvakadai se calcium carbonate nevhu);
(2) Deredza kupora shrinkage rate kudzivirira kutsemuka uye deformation kunokonzerwa shrinkage (yakadai se calcium carbonate, quartz powder, girazi microspheres, nezvimwewo);
(3) Kuvandudza resin viscosity panguva yekuumba uye kudzivirira resin kudonha.Nekudaro, zvinofanirwa kucherechedzwa kuti kuwedzera zvakanyanya mu viscosity dzimwe nguva kunogona kuve kukanganisa;
(4) Kusajeka kwezvinhu zvakagadzirwa (zvakadai se calcium carbonate nevhu);
(5) Kuchena kwezvinhu zvakagadzirwa (senge barium sulfate uye lithopone);
(6) Kuvandudza kushorwa kwezvigadzirwa zvakaumbwa (mica, girazi mashizha, nezvimwewo);
(7) Kuvandudza kupikisa kwemurazvo wezvigadzirwa zvakagadzirwa (aluminium hydroxide, antimony trioxide, chlorinated parafini);
(8) Kuvandudza kuoma uye kuoma kwezvinhu zvakagadzirwa (zvakadai se calcium carbonate, girazi microspheres, nezvimwewo);
(9) Kuvandudza simba rezvigadzirwa zvakaumbwa (girazi poda, potassium titanate fibers, nezvimwewo);
(10) Kuvandudza huremu uye zvivakwa zvekudzivirira zvezvigadzirwa zvakaumbwa (akasiyana mamicrospheres);
(11) Ipa kana kuwedzera thixotropy ye resin yakasanganiswa (yakadai se ultrafine anhydrous silica, girazi poda, nezvimwewo).
Zvinogona kuoneka kuti chinangwa chekuwedzera mafirita kune resins chakasiyana, saka zvakakosha kuti usarudze akakodzera mafirita zvichienderana nezvinangwa zvakasiyana kuti ushandise zvizere basa remafirita.
2. Kuchengetedza kusarudzwa uye kushandiswa kwekuzadza
Kune marudzi akasiyana-siyana ekuzadza.Naizvozvo, zvinodikanwa kusarudza iyo yakakodzera yekuzadza brand uye giredhi nechinangwa chekushandisa, izvo zvinoenda pasina kutaura.Iwo akajairika ekuchengetedza pakusarudza mafirita haasi ega ega ega ega ega ega ega ega nemutengo wakagara watemwa uye kuita, asi zvakare kuterera kune anotevera mapoinzi:
(1) Huwandu hweresin inobatwa hunofanira kuva pakati nepakati.Huwandu hweresin hwakanyudzwa hune hunhu hwakakura pane viscosity ye resin musanganiswa.
(2) Iyo viscosity yemusanganiswa we resin inofanirwa kuve yakakodzera kuumbwa kwekushanda.Magadzirirwo akati wandei kune viscosity ye resin musanganiswa anogona kuitwa nekunyungudika ne styrene, asi kuwedzera akawandisa mafirita uye diluting ne styrene zvinotungamira mukudzikira kweFRP kuita.Iyo viscosity yemusanganiswa we resin dzimwe nguva inokanganiswa zvakanyanya nehuwandu hwekusanganisa, mamiriro ekusanganisa, kana kuwedzera kwekuzadza pamusoro modhifita.
(3) Maitiro ekurapa emusanganiswa we resin anofanirwa kuve akakodzera mamiriro ekuumba.Mamiriro ekurapa emusanganiswa we resin dzimwe nguva anopesvedzerwa neazadza pachayo kana adsorbed kana yakasanganiswa hunyoro uye zvinhu zvekunze mune filler.
(4) Iyo resin musanganiswa inofanira kuramba yakagadzikana kweimwe nguva yenguva.Kune chiitiko chekugadzirisa uye kupatsanurwa kwemafirita nekuda kwekumira, dzimwe nguva inogona kudzivirirwa nekupa resin nethixotropy.Dzimwe nguva, nzira yekudzivirira static uye inoenderera mberi mechani inobvongodza inoshandiswawo kudzivirira kugadziriswa kwemafirita, asi mune iyi kesi, zvinofanirwa kufunga nezve kudzivirira kugadzirisa uye kuunganidza mafirita mupombi kubva mumudziyo une musanganisi kusvika pakugadzira. site.Kana mamwe ma microbead mafirita akada kupatsanurwa kumusoro, zvinodikanwa kusimbisazve giredhi.
(5) Kupinda kwemusanganiswa we resin kunofanirwa kuve kwakakodzera kune yeanoshanda tekinoroji level.Kuwedzerwa kwemafirita kazhinji kunoderedza kujeka kwemusanganiswa weresin uye zvakare kunoderedza ductility yeresin panguva yekuisa.Naizvozvo, kuisirwa pamuviri, kuburitsa furo, uye kutonga panguva yekuumbwa kwave kwakaoma.Izvi zvinhu zvinofanirwa kutariswa kuti zvione chiyero chemusanganiswa we resin.
(6) Kuchenjerera kunofanira kubhadharwa kune chaiyo giravhiti yemusanganiswa weresin.Paunenge uchishandisa mafirita sezvinhu zvekuwedzera kuderedza mutengo wezvinhu, iyo chaiyo giravhiti yemusanganiswa weresin inowedzera kana ichienzaniswa neresin, dzimwe nguva isingasviki kukosha kwaitarisirwa kudzikisa mitengo yezvinhu.
(7) Mhedzisiro yepasi pekugadzirisa mafiritsi inofanira kuongororwa.Mafiller surface modifiers anoshanda mukudzikisa viscosity yemusanganiswa weresin, uye akasiyana epamusoro ekugadzirisa dzimwe nguva anogona kuvandudza simba remuchina mukuwedzera pakuramba mvura, kuramba kwemamiriro ekunze, uye kuramba kwemakemikari.Kune zvakare mhando dzemafirita akarapwa pamusoro, uye mamwe anoshandisa iyo inonzi "yose kusanganisa nzira" kugadzirisa pamusoro pemafirita.Ndokunge, pakusanganisa resin musanganiswa, mafirita uye modifiers anowedzerwa pamwechete kune resin, dzimwe nguva mhedzisiro yacho yakanaka kwazvo.
(8) Kubvisa furo mumusanganiswa we resin kunofanira kunyatsoitwa.Mafirita anowanzo shandiswa muchimiro chemicro powders uye zvimedu, ine yakakura kwazvo yakananga nzvimbo.Panguva imwecheteyo, kune zvakare akawanda zvikamu apo micro powders uye zvimedu zvinoungana pamwe chete.Kuti uparadzire mafiritsi aya muresin, resin inoda kubvongodzwa zvakanyanya, uye mweya unodhonzwa mumusanganiswa.Mukuwedzera, mhepo inokweverwawo muhukuru hukuru hwemafiritsi.Nekuda kweizvozvo, huwandu husingafungidzirwe hwemhepo hwakasanganiswa mumusanganiswa wakagadzirirwa resin, uye mune ino nyika, iyo FRP yakawanikwa nekuipa iyo yekuumba inowanzoitika kuburitsa mabubble uye voids, dzimwe nguva kutadza kuita zvinotarisirwa kuita.Kana zvisingaite kuburitsa furo zvizere chete nekumira wakamira mushure mekusanganisa, kusefa kwebhegi resirika kana kuderedza kudzvinyirira kunogona kushandiswa kubvisa mabhuru.
Pamusoro pemapoinzi ari pamusoro apa, matanho ekudzivirira guruva anofanirwawo kutorwa munzvimbo yekushanda kana uchishandisa mafirita.Zvinhu zvakadai se ultrafine particulate silica inoumbwa nesirica yemahara, alumina, pasi diatomaceous, matombo akaomeswa nechando, nezvimwewo zvinoiswa mukirasi yeguruva, nepo calcium carbonate, girazi poda, girazi flakes, mica, nezvimwe zvinoiswa mukirasi yechipiri guruva.Kune zvakare mirairo pane inodzorwa kuunganidzwa kweakasiyana madiki poda mumhepo yezvakatipoteredza.Zvishandiso zvemuno zvinopedza simba zvinofanirwa kuiswa uye michina yekudzivirira yevashandi inofanirwa kunyatso shandiswa pakubata mafirita ehupfu akadaro.
