Izinzuzo kanye nokubi kokubili kuqhathaniswa kanje:
Ukubekwa kwezandla kuyinqubo yokuvula isikhunta okwamanje esenza u-65% weingilazi fiberizinhlanganisela ze-polyester eziqinisiwe.Izinzuzo zayo ukuthi inezinga elikhulu lenkululeko ekushintsheni ukuma kwesikhunta, intengo yesikhunta iphansi, ukuzivumelanisa nezimo kunamandla, ukusebenza komkhiqizo kuqashelwa yimakethe, futhi ukutshalwa kwezimali kuphansi.Ngakho-ke ifaneleka ngokukhethekile ezinkampanini ezincane, kodwa futhi nasezimbonini zasolwandle kanye ne-aerospace, lapho ngokuvamile iyingxenye enkulu eyodwa.Nokho, kukhona futhi uchungechunge lwezinkinga kule nqubo.Uma ukukhishwa kwe-volatile organic compound (VOC) kudlula izinga, kunomthelela omkhulu empilweni yabasebenzi, kulula ukulahlekelwa abasebenzi, kunemikhawulo eminingi ezintweni ezivumelekile, ukusebenza komkhiqizo kuphansi, futhi inhlaka iyamoshwa. futhi isetshenziswe ngenani elikhulu, ikakhulukazi umkhiqizo.Ikhwalithi ayizinzile.Ingxenye yeingilazi fiber kanye ne-resin, ukushuba kwezingxenye, izinga lokukhiqiza lesendlalelo, nokufana kwesendlalelo konke kuthinteka opharetha, futhi opharetha kudingeka abe nobuchwepheshe obungcono, isipiliyoni kanye nekhwalithi.I-resinOkuqukethwe kwemikhiqizo yokubeka izandla ngokuvamile kungama-50% -70%.Ukukhishwa kwe-VOC kwenqubo yokuvula isikhunta kudlula i-500PPm, futhi ukuvuthwa kwe-styrene kuphezulu njengo-35% -45% yenani elisetshenzisiwe.Imithetho yamazwe ahlukahlukene i-50-100PPm.Njengamanje, amazwe amaningi angaphandle asebenzisa i-cyclopentadiene (DCPD) noma amanye ama-resin aphansi okukhululwa kwe-styrene, kodwa ayikho indawo enhle ye-styrene njenge-monomer.
I-Fiberglass mat inqubo yokubeka isandla
I-vacuum resinInqubo yesingeniso iyinqubo yokukhiqiza engabizi kakhulu eyakhiwe eminyakeni engama-20 edlule, elungele ukukhiqizwa kwemikhiqizo emikhulu.Izinzuzo zayo zimi kanje:
(1) Umkhiqizo unokusebenza okuhle kakhulu kanye nesivuno esikhulu.Endabeni efanayoi-fiberglassizinto zokusetshenziswa, amandla, ukuqina kanye nezinye izakhiwo ezibonakalayo zezingxenye ezethulwe nge-vacuum resin zingathuthukiswa ngaphezu kuka-30% -50% uma kuqhathaniswa nezingxenye zokubeka izandla (Ithebula 1).Ngemuva kokuthi inqubo isizinzile, isivuno singase sisondele ku-100%.

(2) Ikhwalithi yomkhiqizo izinzile futhi ukuphindaphinda kuhle.Ikhwalithi yomkhiqizo ayithinteki kangako opharetha, futhi kukhona izinga eliphezulu lokuvumelana noma ngabe ingxenye efanayo noma phakathi kwezingxenye.Okuqukethwe kwe-fiber yomkhiqizo kufakwe esikhunjini ngokuya ngenani elishiwo ngaphambi kokuba i-resin ijovwe, futhi izingxenye zinesilinganiso esingaguquki se-resin, ngokuvamile esingu-30% -45%, ngakho-ke ukufana nokuphindaphinda kokusebenza komkhiqizo kangcono kunemikhiqizo yenqubo yokubeka isandla.okuningi, kanye neziphambeko ezimbalwa.
(3) Ukusebenza okulwa nokukhathala kuyathuthukiswa, okunganciphisa isisindo sesakhiwo.Ngenxa yokuqukethwe kwe-fiber ephezulu, i-porosity ephansi nokusebenza komkhiqizo ophezulu, ikakhulukazi ukuthuthukiswa kwamandla e-interlaminar, ukumelana nokukhathala komkhiqizo kuthuthukiswa kakhulu.Endabeni yamandla afanayo noma izidingo zokuqina, imikhiqizo eyenziwe inqubo yokungeniswa kwe-vacuum inganciphisa isisindo sesakhiwo.
(4) Ayinandaba nemvelo.Inqubo yokufakwa kwe-vacuum resin iyinqubo yokukhunta evaliwe lapho izinto eziphilayo eziguquguqukayo kanye nezinto ezingcolisa umoya ezinobuthi zivalelwe esikhwameni sevacuum.Ukulandelela kuphela amanani okuguquguquka akhona lapho iphampu yevacuum ikhishwa (iyahluzwa) futhi umphongolo we-resin uvuliwe.Ukukhishwa kwe-VOC akudluli izinga le-5PPm.Lokhu futhi kuthuthukisa kakhulu indawo yokusebenza yabaqhubi, kusimamise abasebenzi, futhi kwandise ububanzi bezinto ezitholakalayo.
(5) Ubuqotho bomkhiqizo buhle.Inqubo yokwethulwa kwe-vacuum resin ingakha izimbambo eziqinisayo, izakhiwo zesemishi nokunye okufakwayo ngesikhathi esifanayo, okuthuthukisa ubuqotho bomkhiqizo, ngakho-ke imikhiqizo emikhulu efana nama-fan hoods, imikhumbi yemikhumbi kanye nezakhiwo ezinkulu zingenziwa.
(6) Yehlisa ukusetshenziswa kwezinto ezingavuthiwe kanye nomsebenzi.Ekuhleleni okufanayo, inani le-resin liyancipha ngo-30%.Imfucuza encane, izinga lokulahlekelwa kwe-resin lingaphansi kuka-5%.Ukukhiqiza okuphezulu kwabasebenzi, ukonga abasebenzi abangaphezu kuka-50% uma kuqhathaniswa nenqubo yokubeka izandla.Ikakhulukazi ekubunjweni kwama-geometries amakhulu futhi ayinkimbinkimbi wesemishi kanye nezingxenye zesakhiwo eziqinisiwe, ukonga okubonakalayo nokongiwa kwabasebenzi kukhulu nakakhulu.Isibonelo, ekukhiqizeni ama-rudders aqondile embonini yezindiza, izindleko zokunciphisa izinsimbi ngo-365 zehliswa ngo-75% uma kuqhathaniswa nendlela yendabuko, isisindo somkhiqizo sihlala singashintshiwe, futhi ukusebenza kungcono.
(7) Ukunemba komkhiqizo kuhle.Ukunemba kohlangothi (ukuqina) kwemikhiqizo yenqubo yokwethulwa kwe-vacuum resin kungcono kunokwemikhiqizo yokubeka izandla.Ngaphansi kokwakheka okufanayo, ubukhulu bemikhiqizo yobuchwepheshe bokusabalalisa i-vacuum resin evamile bungu-2/3 wemikhiqizo yokubeka izandla.Ukuchezuka kogqinsi lomkhiqizo cishe ku-±10%, kuyilapho inqubo yokubeka isandla ngokuvamile iba ±20%.Ukucaba kwendawo yomkhiqizo kungcono kunokwemikhiqizo yokubeka izandla.Udonga lwangaphakathi lomkhiqizo we-hood wenqubo yokwethulwa kwe-vacuum resin bushelelezi, futhi indawo engaphezulu yakha ngokwemvelo ungqimba olucebile nge-resin, olungadingi ijazi elingaphezulu elingeziwe.Ukuncishiswa kwabasebenzi kanye nezinto zokwenziwa kwesihlabathi nokupenda.
Vele, inqubo yamanje yokwethulwa kwe-vacuum resin nayo inezinkinga ezithile:
(1) Inqubo yokulungiselela ithatha isikhathi eside futhi iyinkimbinkimbi kakhulu.Kudingeka ukuhleleka okufanele, ukubekwa kwemidiya yokuphambukisa, amashubhu okuphambukisa, ukuvala isivalo okusebenzayo okusebenzayo, njll.Ngakho-ke, emikhiqizweni emincane, isikhathi senqubo side kunenqubo yokubeka isandla.
(2) Izindleko zokukhiqiza ziphezulu futhi kukhiqizwa imfucuza eyengeziwe.Izinto ezisizayo ezifana nefilimu yesikhwama se-vacuum, i-diversion medium, indwangu yokukhulula kanye ne-diversion tube konke kuyalahlwa, futhi eziningi zazo zingenisiwe njengamanje, ngakho-ke izindleko zokukhiqiza ziphezulu kunenqubo yokubeka isandla.Kodwa uma umkhiqizo umkhulu, umehluko uba mncane.Ngokwenziwa kwasendaweni kwezinto ezisizayo, lo mehluko wezindleko uya ngokuya uba mncane futhi ube mncane.Ucwaningo lwamanje lwezinto ezisizayo ezingasetshenziswa izikhathi eziningi luyisiqondiso sokuthuthukiswa kwale nqubo.
(3) Ukukhiqiza inqubo kunezingozi ezithile.Ikakhulukazi emikhiqizweni emikhulu neyinkimbinkimbi yesakhiwo, uma ukumnika kwe-resin kwehluleka, umkhiqizo kulula ukuchithwa.
Ngakho-ke, ucwaningo olungcono lokuqala, ukulawulwa kwenqubo okuqinile kanye nezinyathelo zokulungisa ezisebenzayo kuyadingeka ukuze kuqinisekiswe impumelelo yenqubo.
Imikhiqizo yenkampani yethu:
Ukuzulazula kwe-Fiberglass, i-fiberglassukuzulazula okwelukiweyo, amacansi e-fiberglass, indwangu ye-fiberglass mesh,unsaturated polyester resin, vinyl ester resin, epoxy resin, gel coat resin, asizayo for FRP, carbon fibre nezinye izinto zokusetshenziswa for FRP.
