Iingenelo kunye nokungalungi kwezi zimbini zithelekiswa ngolu hlobo lulandelayo:
Ukubeka isandla yinkqubo evulekileyo okwangoku ebandakanya ama-65%ifayibha yeglasiii-polyester composites eziqinisiweyo. Iingenelo zayo kukuba inenkululeko enkulu ekutshintsheni imo yesikhunta, ixabiso lesikhunta liphantsi, ukulungelelaniswa kwayo kunamandla, ukusebenza kwemveliso kuyaqatshelwa yimarike, kwaye utyalo-mali luphantsi. Ngoko ke ifanelekile ngakumbi kwiinkampani ezincinci, kodwa nakwimizi-mveliso yolwandle neyeenqwelo-moya, apho idla ngokuba yinxalenye enkulu kube kanye. Nangona kunjalo, kukwakho nothotho lweengxaki kule nkqubo. Ukuba ukukhutshwa kwe-volatile organic compound (VOC) kudlula umgangatho, kunempembelelo enkulu kwimpilo yabaqhubi, kulula ukulahlekelwa ngabasebenzi, kukho imiqathango emininzi kwizinto ezivumelekileyo, ukusebenza kwemveliso kuphantsi, kwaye i-resin iyachithwa kwaye isetyenziswe ngobuninzi, ingakumbi imveliso. Umgangatho awuzinzanga. Umlinganiselo weifayibha yeglasi kunye ne-resin, ubukhulu beendawo, isantya sokuveliswa kweleya, kunye nokufana kweleya zonke ziyachaphazeleka ngumsebenzisi, kwaye umsebenzisi kufuneka abe netekhnoloji engcono, amava kunye nomgangatho.I-resinUmxholo weemveliso ezibekwe ngesandla ngokubanzi umalunga ne-50%-70%. Ukukhutshwa kwe-VOC kwenkqubo yokuvula isikhunta kudlula i-500PPm, kwaye ukuguquguquka kwe-styrene kuphezulu ukuya kwi-35%-45% yesixa esisetyenzisiweyo. Imithetho yamazwe ahlukeneyo yi-50-100PPm. Okwangoku, uninzi lwamazwe angaphandle asebenzisa i-cyclopentadiene (DCPD) okanye ezinye ii-resins ezikhutshwayo ze-styrene ephantsi, kodwa akukho nto ilungileyo endaweni ye-styrene njenge-monomer.
Imathi yeglasi yefayibha inkqubo yokubeka ngesandla
I-resin ye-vacuumInkqubo yokwazisa yinkqubo yokuvelisa engabizi kakhulu eyaphuhliswa kwiminyaka engama-20 edlulileyo, efanelekileyo ngakumbi ekuvelisweni kweemveliso ezinkulu. Iingenelo zayo zezi zilandelayo:
(1) Imveliso isebenza kakuhle kakhulu kwaye inemveliso ephezulu.Kwimeko efanayoi-fiberglassIzinto ezisetyenzisiweyo, amandla, ukuqina kunye nezinye iimpawu zomzimba zezinto ezifakwe kwi-vacuum resin zinokuphucuka ngaphezulu kwe-30%-50% xa kuthelekiswa nezinto ezibekwe ngesandla (Itheyibhile 1). Emva kokuba inkqubo izinzisiwe, isivuno singasondela kwi-100%.

(2) Umgangatho wemveliso uzinzile kwaye ukuphindaphindwa kwayo kulungile.Umgangatho wemveliso awuchaphazeleki kangako ngabaqhubi, kwaye kukho izinga eliphezulu lokungaguquguquki nokuba yinxalenye efanayo okanye phakathi kwezixhobo. Umxholo wefayibha yemveliso ufakwe kwi-mold ngokwesixa esichaziweyo ngaphambi kokuba i-resin ifakwe, kwaye izixhobo zinomlinganiselo we-resin ohlala uhleli, ngokubanzi yi-30%-45%, ngoko ke ukufana kunye nokuphindaphinda kokusebenza kwemveliso kungcono kuneemveliso zenkqubo yokubeka ngesandla.
(3) Ukusebenza kokulwa nokudinwa kuyaphucuka, nto leyo enokunciphisa ubunzima besakhiwo.Ngenxa yomxholo ophezulu wefayibha, ukuvuleka okuphantsi kunye nokusebenza okuphezulu kwemveliso, ngakumbi ukuphuculwa kwamandla e-interlaminar, ukumelana nokudinwa kwemveliso kuphucuka kakhulu. Kwimeko yamandla afanayo okanye ukuqina, iimveliso ezenziwe yinkqubo yokungenisa i-vacuum zinokunciphisa ubunzima besakhiwo.
(4) Ayinabungozi kokusingqongileyo.Inkqubo yokufaka i-vacuum resin yinkqubo yokubumba evaliweyo apho izinto eziphilayo eziguquguqukayo kunye nongcoliseko lomoya olunobuthi lugcinwa kwingxowa yokuphunga. Kuphela zizinto ezincinci eziguquguqukayo ezikhoyo xa ipompo yokuphunga ingena umoya (ihluzwa) kwaye ibhereli ye-resin ivuliwe. Ukukhutshwa kwe-VOC akudluli umgangatho we-5PPm. Oku kukwaphucula kakhulu imeko yokusebenza yabasebenzi, kuzinzisa abasebenzi, kwaye kwandisa uluhlu lwezinto ezikhoyo.
(5) Ukuthembeka kwemveliso kulungile.Inkqubo yokungenisa i-vacuum resin inokwenza iimbambo zokuqinisa, izakhiwo zesandwich kunye nezinye izinto ezifakelwayo ngaxeshanye, nto leyo ephucula ukuthembeka kwemveliso, ngoko ke iimveliso ezinkulu ezifana nee-fan hoods, ii-ship hulls kunye nezakhiwo ezinkulu zinokwenziwa.
(6) Nciphisa ukusetyenziswa kwezinto ezikrwada kunye nabasebenzi.Kwi-layup efanayo, ubungakanani be-resin buncitshiswa ngama-30%. Inkunkuma encinci, izinga lokulahleka kwe-resin lingaphantsi kwe-5%. Imveliso ephezulu yabasebenzi, ukonga abasebenzi okungaphezulu kwama-50% xa kuthelekiswa nenkqubo yokubeka ngesandla. Ingakumbi ekubunjweni kwejometri ezinkulu nezintsonkothileyo zesandwich kunye neendawo eziqinisiweyo zesakhiwo, ukonga kwezinto kunye nabasebenzi kubaluleke kakhulu. Umzekelo, ekwenziweni kwee-rudders ezithe nkqo kwishishini leenqwelo moya, iindleko zokunciphisa izibophelelo ngama-365 zincitshiswa ngama-75% xa kuthelekiswa nendlela yendabuko, ubunzima bemveliso abutshintshi, kwaye ukusebenza kungcono.
(7) Ukuchaneka kwemveliso kulungile.Ukuchaneka kobukhulu (ubukhulu) beemveliso zenkqubo yokungenisa i-vacuum resin kungcono kunokweemveliso zokubeka ngesandla. Phantsi kwe-layup efanayo, ubukhulu beemveliso zobuchwepheshe bokusasazwa kwe-vacuum resin yi-2/3 yobukhulu beemveliso zokubeka ngesandla. Ukuphambuka kobukhulu bemveliso kumalunga ne-±10%, ngelixa inkqubo yokubeka ngesandla iqhele ukuba yi-±20%. Ukuthe tyaba komphezulu wemveliso kubhetele kunokweemveliso zokubeka ngesandla. Udonga lwangaphakathi lwemveliso ye-hood yenkqubo yokungenisa i-vacuum resin lugudileyo, kwaye umphezulu wenza umaleko otyebileyo we-resin, ongadingi top coat eyongezelelweyo. Abasebenzi abanciphileyo kunye nezixhobo zenkqubo yokusila nokupeyinta.
Kakade ke, inkqubo yokungenisa i-vacuum resin yangoku ikwanazo nezinye iingxaki:
(1) Inkqubo yokulungiselela ithatha ixesha elide kwaye iyinkimbinkimbi ngakumbi.Kufuneka ukubekwa ngendlela efanelekileyo, ukubekwa kwezixhobo zokuhambisa amanzi, iityhubhu zokuhambisa amanzi, ukuvalwa kwe-vacuum okusebenzayo, njl.njl. Ke ngoko, kwiimveliso ezincinci, ixesha lenkqubo lide kunenkqubo yokubeka ngesandla.
(2) Iindleko zemveliso ziphezulu kwaye kuvela inkunkuma eninzi.Izinto ezincedisayo ezifana nefilimu yengxowa ye-vacuum, i-diversion medium, ilaphu lokukhulula kunye netyhubhu yokukhupha zonke ziyalahlwa, kwaye uninzi lwazo zingeniswa ngoku, ngoko ke iindleko zemveliso ziphezulu kunenkqubo yokubeka ngesandla. Kodwa okukhona imveliso inkulu, kokukhona umahluko umncinci. Ngokusetyenziswa kwezixhobo ezincedisayo, lo mahluko weendleko uya uncipha. Uphando lwangoku ngezinto ezincedisayo ezinokusetyenziswa amaxesha amaninzi luyindlela yophuhliso lwale nkqubo.
(3) Ukwenziwa kwenkqubo kuneengozi ezithile.Ingakumbi kwiimveliso ezinkulu nezintsonkothileyo zesakhiwo, xa ukufunxwa kweresin kungaphumeleli, imveliso kulula ukuyilahla.
Ngoko ke, uphando olungcono lokuqala, ulawulo olungqongqo lwenkqubo kunye namanyathelo okulungisa asebenzayo ayafuneka ukuqinisekisa impumelelo yenkqubo.
