1. Karolo ea ho tlatsa lisebelisoa
Eketsa li-filler tse kang calcium carbonate, letsopa, aluminium hydroxide, li-flakes tsa khalase, li-microbeads tsa khalase, le lithopone ho resin ea polyester ebe u li hasanya ho etsa motsoako oa resin.Mosebetsi oa eona ke o latelang:
(1) Fokotsa litšenyehelo tsa thepa ea FRP (e kang calcium carbonate le letsopa);
(2) Fokotsa lebelo la ho fokotsa ho folisa ho thibela mapetsong le ho senyeha ho bakoang ke ho fokotseha (joaloka calcium carbonate, phofo ea quartz, microspheres ea khalase, joalo-joalo);
(3) Ntlafatsa viscosity ea resin nakong ea ho bopa le ho thibela ho rotha ha resin.Leha ho le joalo, hoa lokela ho hlokomeloa hore ho eketseha ho feteletseng ha viscosity ka linako tse ling ho ka ba kotsi;
(4) Ho se be pepeneneng ha lihlahisoa tse entsoeng (tse kang calcium carbonate le letsopa);
(5) Ho soeufala ha lihlahisoa tse entsoeng (tse kang barium sulfate le lithopone);
(6) Ntlafatsa khanyetso ea kutu ea lihlahisoa tse entsoeng (mica, maqephe a khalase, joalo-joalo);
(7) Ntlafatsa ho hanyetsa lelakabe la lihlahisoa tse entsoeng (aluminium hydroxide, antimony trioxide, parafine ea chlorinated);
(8) Ntlafatsa ho thatafala le ho satalla ha lihlahisoa tse entsoeng (tse kang calcium carbonate, glass microspheres, joalo-joalo);
(9) Ntlafatsa matla a lihlahisoa tse entsoeng (phofo ea khalase, likhoele tsa potassium titanate, joalo-joalo);
(10) Ntlafatsa thepa e bobebe le ea ho kenya letsoho ea lihlahisoa tse bōpiloeng (li-microsphere tse fapa-fapaneng);
(11) Fana ka kapa ho eketsa thixotropy ea metsoako ea resin (e kang ultrafine anhydrous silica, phofo ea khalase, joalo-joalo).
Hoa hlokomeleha hore morero oa ho eketsa li-filler ho li-resin o fapane, kahoo ho bohlokoa ho khetha li-fillers tse loketseng ho ea ka merero e fapaneng ho sebelisa ka botlalo karolo ea li-fillers.
2. Litlhokomelo bakeng sa khetho le tšebeliso ea li-fillers
Ho na le mefuta e fapaneng ea li-fillers.Ka hona, hoa hlokahala ho khetha mofuta o nepahetseng oa li-filler le kereiti molemong oa ts'ebeliso, e sa reng letho.Litlhokomelo tse akaretsang ha u khetha li-fillers ha se feela ho khetha mefuta e fapaneng ka litšenyehelo tse reriloeng esale pele le ts'ebetso, empa hape le ho ela hloko lintlha tse latelang:
(1) Tekanyo ea resin e monyelitsoeng e lokela ho ba e itekanetseng.Palo ea resin e monyelitsoeng e na le tšusumetso e kholo ho viscosity ea metsoako ea resin.
(2) Viscosity ea motsoako oa resin e lokela ho ba e loketseng bakeng sa ts'ebetso ea ho bōpa.Liphetoho tse 'maloa ho viscosity ea metsoako ea resin li ka etsoa ka ho hlapolla ka styrene, empa ho eketsa li-filler tse ngata le ho hlapolla ka styrene ho tla lebisa ho fokotseha ha ts'ebetso ea FRP.Viscosity ea metsoako ea resin ka linako tse ling e angoa haholo ke palo ea ho kopanya, maemo a ho kopanya, kapa ho eketsoa ha li-filler surface modifiers.
(3) Litšobotsi tsa ho phekola tsa motsoako oa resin li lokela ho ba tse loketseng maemo a ho bōpa.Litšobotsi tsa ho folisa tsa motsoako oa resin ka linako tse ling li susumetsoa ke ho tlatsa ka boeona kapa mongobo o kentsoeng kapa o tsoakiloeng le lintho tse tsoang kantle ho setlamo.
(4) Motsoako oa resin o lokela ho lula o tsitsitse ka nako e itseng.Bakeng sa ts'ebetso ea ho rarolla le ho arohana ha li-filler ka lebaka la ho ema, ka linako tse ling e ka thibeloa ka ho fana ka resin ka thixotropy.Ka linako tse ling, mokhoa oa ho qoba ts'ebetso e tsitsitseng le e tsoelang pele ea mochini e boetse e sebelisoa ho thibela ho rarolloa ha li-fillers, empa tabeng ena, ho bohlokoa ho nahana ka ho thibela ho rarolla le ho bokella li-filler ka pipeline ho tloha ka setshelo se nang le mixer ho ea ho theha. sebaka.Ha li-fillers tse ling tsa microbead li sekametse karohanong e eang holimo, hoa hlokahala ho netefatsa boemo hape.
(5) The permeability ea motsoako oa resin e lokela ho ba tse loketseng boemo ba botekgeniki ba opareitara.Ho eketsoa ha li-filler ka kakaretso ho fokotsa pepeneneng ea motsoako oa resin hape ho fokotsa ductility ea resin nakong ea ho beha.Ka hona, ho emola, ts'ebetso ea ho tlosa lekoba, le kahlolo nakong ea ho bōptjoa ho se ho le boima.Lintlha tsena li lokela ho nahanoa ho fumana karo-karolelano ea motsoako oa resin.
(6) Tlhokomelo e lokela ho lefshoa ho boima bo khethehileng ba motsoako oa resin.Ha o sebelisa li-filler e le lisebelisoa tse eketsang ho fokotsa litšenyehelo tsa thepa, matla a khoheli a motsoako oa resin a eketseha ha a bapisoa le resin, ka linako tse ling ha a fihlelle boleng bo lebelletsoeng ba ho fokotsa litšenyehelo tsa thepa ka mokhoa o hlakileng.
(7) Phello ea phetoho ea bokaholimo ba li-filler e lokela ho hlahlojoa.Li-filler surface modifiers li sebetsa hantle ho fokotsa viscosity ea metsoako ea resin, 'me ka linako tse ling li-modifiers tse fapaneng li ka ntlafatsa matla a mochini ho kenyelletsa ho hanyetsa metsi, ho hanyetsa boemo ba leholimo le khanyetso ea lik'hemik'hale.Ho boetse ho na le mefuta ea li-filler tse kileng tsa phekoloa ka holim'a metsi, 'me tse ling li sebelisa seo ho thoeng ke "mokhoa oohle oa ho kopanya" ho fetola bokaholimo ba li-filler.Ke hore, ha u kopanya metsoako ea resin, li-fillers le li-modifiers li kenngoa hammoho ho resin, ka linako tse ling phello e ntle haholo.
(8) Ho tlosa lekoba ka har'a motsoako oa resin ho lokela ho etsoa ka botlalo.Hangata li-fillers li sebelisoa ka mokhoa oa li-micro powders le likaroloana, tse nang le sebaka se seholo haholo se khethehileng.Ka nako e ts'oanang, ho boetse ho na le likarolo tse ngata moo li-micro powders le likaroloana li kopanang.E le ho hasanya li-filler tsena ka har'a resin, resin e hloka ho ts'oaroa ka matla, 'me moea o huloa ka har'a motsoako.Ho feta moo, moea o boetse o huleloa ka bongata bo boholo ba li-fillers.Ka lebaka leo, moea o ke keng oa nahanoa o ne o kopantsoe ka har'a motsoako o lokiselitsoeng oa resin, 'me sebakeng sena, FRP e fumanoeng ka ho fana ka eona bakeng sa ho bopa e atisa ho hlahisa li-bubble le li-voids, ka linako tse ling e hlōleha ho finyella ts'ebetso e lebeletsoeng.Ha ho ke ke ha khoneha ho tlosa lekoba ka ho feletseng ka ho ema feela ka mor'a ho kopanya, ho hloekisa mokotla oa silika kapa ho fokotsa khatello ho ka sebelisoa ho tlosa li-bubble.
Ho phaella lintlheng tse ka holimo, mehato ea ho thibela lerōle le eona e lokela ho nkoa sebakeng sa mosebetsi ha u sebelisa li-fillers.Lintho tse kang ultrafine particulate silica e entsoeng ka silica e sa lefelloeng, alumina, lefatše la diatomaceous, majoe a leqhoa, joalo-joalo li khetholloa e le lerōle la Sehlopha sa I, ha calcium carbonate, phofo ea khalase, li-flakes tsa khalase, mica, joalo-joalo li khetholloa e le lerōle la Sehlopha sa II.Ho boetse ho na le melaoana mabapi le khatello e laoloang ea li-powders tse fapaneng sepakapakeng sa tikoloho.Lisebelisoa tsa sebakeng sa heno li tlameha ho kengoa 'me lisebelisoa tsa ts'ireletso ea basebetsi li tlameha ho sebelisoa ka thata ha ho ts'oaroa li-filler tse joalo tse phofshoana.
