Izinzuzo kanye nokungalungi kwalokhu okubili kuqhathaniswa kanje:
Ukubeka izandla kuyinqubo evulekile okwamanje ebangela u-65%i-fiber yengilaziIzinhlanganisela ze-polyester eziqinisiwe. Izinzuzo zayo ukuthi inezinga elikhulu lenkululeko ekushintsheni isimo sesikhunta, intengo yesikhunta iphansi, ukuzivumelanisa nezimo kunamandla, ukusebenza komkhiqizo kuyaqashelwa yimakethe, futhi utshalomali luphansi. Ngakho-ke ifaneleka kakhulu ezinkampanini ezincane, kodwa futhi nasezimbonini zasolwandle nezezindiza, lapho ngokuvamile iyingxenye enkulu khona kanye. Kodwa-ke, kukhona nochungechunge lwezinkinga kule nqubo. Uma ukukhishwa kwe-volatile organic compound (VOC) kudlula izinga, kunomthelela omkhulu empilweni yabasebenzi, kulula ukulahlekelwa ngabasebenzi, kunemikhawulo eminingi ezintweni ezivunyelwe, ukusebenza komkhiqizo kuphansi, futhi i-resin iyachithwa futhi isetshenziswa ngenani elikhulu, ikakhulukazi umkhiqizo. Ikhwalithi ayizinzile. Ingxenyei-fiber yengilazi kanye ne-resin, ukujiya kwezingxenye, izinga lokukhiqizwa kwesendlalelo, kanye nokufana kwesendlalelo konke kuthinteka ngumsebenzisi, futhi umsebenzisi kudingeka abe nobuchwepheshe obungcono, ulwazi kanye nekhwalithi.I-resinOkuqukethwe kwemikhiqizo yokubeka ngesandla ngokuvamile kucishe kube ngu-50%-70%. Ukukhishwa kwe-VOC kwenqubo yokuvula isikhunta kudlula u-500PPm, kanti ukuguquguquka kwe-styrene kuphakeme njengo-35%-45% wenani elisetshenzisiwe. Imithetho yamazwe ahlukahlukene ingu-50-100PPm. Njengamanje, amazwe amaningi angaphandle asebenzisa i-cyclopentadiene (DCPD) noma amanye ama-resins aphansi okukhululwa kwe-styrene, kodwa akukho okunye okuhle okufakwa esikhundleni se-styrene njenge-monomer.
Umata we-fiberglass inqubo yokubeka ngesandla
I-resin ye-vacuumInqubo yokwethula inqubo yokukhiqiza engabizi kakhulu eyasungulwa eminyakeni engama-20 edlule, efanelekile kakhulu ekukhiqizweni kwemikhiqizo emikhulu. Izinzuzo zayo yilezi ezilandelayo:
(1) Umkhiqizo usebenza kahle kakhulu futhi ukhiqiza kakhulu.Uma kwenzeka okufanayoi-fiberglassizinto zokusetshenziswa, amandla, ukuqina kanye nezinye izakhiwo zomzimba zezingxenye ezethulwe nge-vacuum resin kungathuthukiswa ngaphezu kuka-30%-50% uma kuqhathaniswa nezingxenye ezibekwe ngesandla (Ithebula 1). Ngemva kokuba inqubo isizinzile, isivuno singaba cishe ku-100%.

(2) Ikhwalithi yomkhiqizo izinzile futhi ukuphindwa kwayo kuhle.Ikhwalithi yomkhiqizo ayithinteki kakhulu ngabaqhubi, futhi kunezinga eliphezulu lokuvumelana kungakhathaliseki ukuthi iyisakhi esifanayo noma phakathi kwezakhi. Okuqukethwe kwefayibha yomkhiqizo kufakwe esikhumbeni ngokwenani elibekiwe ngaphambi kokuba kufakwe i-resin, futhi izakhi zinesilinganiso se-resin esingaguquki, ngokuvamile esingu-30%-45%, ngakho-ke ukufana kanye nokuphindaphindeka kokusebenza komkhiqizo kungcono kunemikhiqizo yenqubo yokubeka ngesandla.
(3) Ukusebenza kokulwa nokukhathala kuyathuthuka, okunganciphisa isisindo sesakhiwo.Ngenxa yokuqukethwe okuphezulu kwefayibha, ukuvuleka okuphansi kanye nokusebenza okuphezulu komkhiqizo, ikakhulukazi ukuthuthukiswa kwamandla e-interlaminar, ukumelana kokukhathala komkhiqizo kuthuthuka kakhulu. Uma kunezidingo ezifanayo zamandla noma ukuqina, imikhiqizo eyenziwe yinqubo yokungenisa i-vacuum inganciphisa isisindo sesakhiwo.
(4) Inobungani nemvelo.Inqubo yokufaka i-vacuum resin iyinqubo yokubumba evaliwe lapho izinto eziphilayo eziguquguqukayo kanye nokungcola komoya okunobuthi kugcinwe esikhwameni se-vacuum. Kuphela inani elincane lezinto eziguquguqukayo ezikhona lapho iphampu ye-vacuum ivulwa (ihlungwa) futhi umgqomo we-resin uvulwa. Ukukhishwa kwe-VOC akudluli izinga elingu-5PPm. Lokhu futhi kuthuthukisa kakhulu indawo yokusebenza yabasebenzi, kuzinzisa abasebenzi, futhi kwandise ububanzi bezinto ezitholakalayo.
(5) Ubuqotho bomkhiqizo buhle.Inqubo yokwethula i-vacuum resin ingakha izimbambo zokuqinisa, izakhiwo ze-sandwich kanye nezinye izinto zokufaka ngesikhathi esisodwa, okuthuthukisa ubuqotho bomkhiqizo, ngakho-ke kungenziwa imikhiqizo emikhulu efana nama-fan hoods, ama-ship hulls kanye nezakhiwo ezinkulu.
(6) Nciphisa ukusetshenziswa kwezinto zokusetshenziswa kanye nomsebenzi.Ku-layup efanayo, inani le-resin lincishiswa ngo-30%. Imfucuza encane, izinga lokulahlekelwa yi-resin lingaphansi kuka-5%. Ukukhiqiza okuphezulu kwabasebenzi, ukonga abasebenzi okungaphezu kuka-50% uma kuqhathaniswa nenqubo yokubeka ngesandla. Ikakhulukazi ekubunjweni kwamajiyometri amakhulu futhi ayinkimbinkimbi esandwich kanye nezingxenye zesakhiwo eziqinisiwe, ukonga kwezinto zokwakha kanye nabasebenzi kukhulu kakhulu. Isibonelo, ekwakhiweni kwama-rudders aqondile embonini yezindiza, izindleko zokunciphisa izikhonkwane ngo-365 zincishiswa ngo-75% uma kuqhathaniswa nendlela yendabuko, isisindo somkhiqizo asishintshi, futhi ukusebenza kungcono.
(7) Ukunemba komkhiqizo kuhle.Ukunemba kobukhulu (ukujiya) kwemikhiqizo yenqubo yokwethula i-vacuum resin kungcono kunokwemikhiqizo yokubeka ngesandla. Ngaphansi kokubekwa okufanayo, ukujiya kwemikhiqizo yobuchwepheshe bokusabalalisa i-vacuum resin ejwayelekile kungu-2/3 kokwemikhiqizo yokubeka ngesandla. Ukuphambuka kobukhulu bomkhiqizo cishe kungu-±10%, kuyilapho inqubo yokubeka ngesandla ngokuvamile ingu-±20%. Ukuthamba kobuso bomkhiqizo kungcono kunokwemikhiqizo yokubeka ngesandla. Udonga lwangaphakathi lomkhiqizo we-hood yenqubo yokwethula i-vacuum resin lubushelelezi, futhi ubuso bakha ngokwemvelo ungqimba olucebile nge-resin, olungadingi ungqimba olungaphezulu olwengeziwe. Kuncishisiwe umsebenzi nezinto zokwakha izinqubo zokusinta nokupenda.
Yiqiniso, inqubo yokwethulwa kwe-vacuum resin yamanje nayo inezinkinga ezithile:
(1) Inqubo yokulungiselela ithatha isikhathi eside futhi iyinkimbinkimbi kakhulu.Kudingeka ukubekwa ngendlela efanele, ukufakwa kwemidiya yokuphambukisa, amashubhu okuphambukisa, ukuvalwa kwe-vacuum okusebenzayo, njll. Ngakho-ke, emikhiqizweni emincane, isikhathi senqubo side kunenqubo yokubekwa ngesandla.
(2) Izindleko zokukhiqiza ziphezulu futhi kukhiqizwa imfucuza eningi.Izinto ezisizayo ezifana nefilimu yesikhwama se-vacuum, i-diversion medium, indwangu yokukhulula kanye ne-diversion tube konke kungalahlwa, futhi eziningi zazo zingeniswa njengamanje, ngakho-ke izindleko zokukhiqiza ziphakeme kunenqubo yokubeka ngesandla. Kodwa uma umkhiqizo umkhulu, umehluko uba mncane. Ngokutholakala kwezinto ezisizayo, lo mehluko wezindleko uya uncipha kancane kancane. Ucwaningo lwamanje ngezinto ezisizayo ezingasetshenziswa izikhathi eziningi luyisiqondiso sokuthuthukiswa kwale nqubo.
(3) Ukukhiqizwa kwezinqubo kunezingozi ezithile.Ikakhulukazi emikhiqizweni emikhulu neyinkimbinkimbi yesakhiwo, uma ukufakwa kwe-resin kwehluleka, umkhiqizo kulula ukuwulahla.
Ngakho-ke, ucwaningo olungcono lokuqala, ukulawulwa kwenqubo okuqinile kanye nezinyathelo zokulungisa ezisebenzayo kuyadingeka ukuqinisekisa impumelelo yenqubo.
Imikhiqizo yenkampani yethu:
Ukuhambahamba nge-fiberglass, i-fiberglassukuzulazula okulukiwe, omata be-fiberglass, indwangu ye-fiberglass ene-mesh,i-polyester resin engagcwali, i-vinyl ester resin, i-epoxy resin, i-gel coat resin, eyisizayo se-FRP, i-carbon fiber nezinye izinto zokusetshenziswa ze-FRP.
