Izinto eziluncedo nezingeloncedo kwezi zimbini zithelekiswa ngolu hlobo lulandelayo:
Ukubekwa kwezandla yinkqubo evulekileyo yokungunda okungoku nje yenza i-65% yeifayibha yeglasiimihlanganisela yepolyester eyomeleziweyo.Iingenelo zayo kukuba inomlinganiselo omkhulu wenkululeko ekutshintsheni ubume bomngundo, ixabiso lokungunda liphantsi, ukuguquguquka kunamandla, ukusebenza kwemveliso kuqatshelwa yimarike, kwaye utyalo-mali luphantsi.Ngoko ifaneleke ngokukodwa kwiinkampani ezincinci, kodwa nakwimizi-mveliso yaselwandle kunye ne-aerospace, apho idla ngokuba yinxalenye enkulu.Nangona kunjalo, kukho kwakhona uluhlu lweengxaki kule nkqubo.Ukuba ukukhutshwa kwe-volatile organic compound (VOC) kudlula umgangatho, kunempembelelo enkulu kwimpilo yabaqhubi, kulula ukulahlekelwa ngabasebenzi, kukho izithintelo ezininzi kwizinto ezivumelekileyo, ukusebenza kwemveliso kuphantsi, kwaye i-resin ichithwa. kwaye isetyenziswe kwisixa esikhulu, ngakumbi imveliso.Umgangatho awuzinzile.Umlinganiselo weifayibha yeglasi kunye ne-resin, ubukhulu beengxenye, izinga lemveliso yomaleko, kunye nokufana komgangatho zonke zichaphazelekayo ngumqhubi, kwaye umqhubi kufuneka abe nobuchwepheshe obungcono, amava kunye nomgangatho.IntlakaIsiqulatho seemveliso zokubeka izandla ngokuqhelekileyo malunga ne-50% -70%.Ukukhutshwa kwe-VOC yenkqubo yokuvula i-mold idlula i-500PPm, kwaye i-volatilization ye-styrene iphezulu njenge-35% -45% yemali esetyenzisiweyo.Imimiselo yamazwe ahlukeneyo yi-50-100PPm.Okwangoku, amazwe amaninzi angaphandle asebenzisa i-cyclopentadiene (DCPD) okanye enye i-resin ephantsi yokukhululwa kwe-styrene, kodwa akukho ndawo ilungileyo ye-styrene njenge-monomer.
I-Fiberglass mat inkqubo yokubeka isandla
I-vacuum resinInkqubo yokwazisa yinkqubo yokwenziwa kwexabiso eliphantsi ephuhliswe kwiminyaka engama-20 edlulileyo, ifaneleke ngakumbi ukwenziwa kweemveliso ezinkulu.Iinzuzo zayo zezi zilandelayo:
(1) Imveliso inokusebenza okugqwesileyo kunye nesivuno esikhulu.Kwimeko efanayoi-fiberglassizinto eziluhlaza, amandla, ukuqina kunye nezinye iimpawu ezibonakalayo ze-vacuum resin-introduced components zingaphuculwa ngaphezu kwe-30% -50% xa kuthelekiswa nezixhobo zokubeka izandla (iThebhile 1).Emva kokuba inkqubo izinzile, isivuno sinokusondela kwi-100%.

(2) Umgangatho wemveliso uzinzile kwaye ukuphindaphinda kulungile.Umgangatho wemveliso awuchatshazelwa kangako ngabaqhubi, kwaye kukho inqanaba eliphezulu lokuhambelana nokuba licandelo elifanayo okanye phakathi kwamacandelo.Umxholo wefiber wemveliso ufakwe kubumba ngokwexabiso elichaziweyo ngaphambi kokuba i-resin itofwe, kwaye amacandelo anomlinganiselo ongatshintshiyo we-resin, ngokubanzi i-30% -45%, ngoko ukufana kunye nokuphindaphinda kwemveliso yemveliso. ngcono kunemveliso yenkqubo yokubeka isandla.ngaphezulu, kunye neziphene ezimbalwa.
(3) Ukusebenza okuchasene nokukhathala kuphuculwe, okunokunciphisa ubunzima besakhiwo.Ngenxa yomxholo wefiber ephezulu, i-porosity ephantsi kunye nokusebenza okuphezulu kwemveliso, ngokukodwa ukuphuculwa kwamandla e-interlaminar, ukuxhathisa ukukhathala kwemveliso kuphuculwe kakhulu.Kwimeko yamandla afanayo okanye iimfuno zokuqina, iimveliso ezenziwe yinkqubo yokufakelwa kwe-vacuum inokunciphisa ubunzima besakhiwo.
(4) Ilungele imeko-bume.Inkqubo yokufakela i-vacuum resin yinkqubo yokubumba evaliweyo apho izinto eziphilayo eziguquguqukayo kunye nezingcolisi zomoya ezinetyhefu zivalelwe kwingxowa yokufunxa.Ukulandelela kuphela iimali eziguquguqukayo ezikhoyo xa ipompo yokufunxa ikhupha umoya (ihluzwayo) kwaye i-resin barrel ivuliwe.Ukukhutshwa kwe-VOC akudluli umgangatho we-5PPm.Oku kukwaphucula kakhulu indawo yokusebenza kubasebenzi, kuzinzisa abasebenzi, nokwandisa uluhlu lwezixhobo ezikhoyo.
(5) Ingqibelelo yemveliso ilungile.Inkqubo yokungeniswa kwe-vacuum resin inokwenza iimbambo zokuqinisa, izakhiwo zesandwich kunye nezinye izinto ezifakelwayo ngexesha elifanayo, eziphucula ukunyaniseka kwemveliso, ngoko ke iimveliso ezinkulu ezifana ne-fan hoods, iinqanawa zeenqanawa kunye ne-superstructures zingenziwa.
(6) Nciphisa ukusetyenziswa kwezinto ezingasetyenziswanga kunye nabasebenzi.Kwi-layup efanayo, inani le-resin liyancipha ngama-30%.Inkunkuma encinci, izinga lokulahleka kwe-resin lingaphantsi kwe-5%.Imveliso ephezulu yabasebenzi, ngaphezulu kwe-50% yokonga abasebenzi xa kuthelekiswa nenkqubo yokubeka izandla.Ngokukodwa ekubunjweni kweejometri ezinkulu kunye nezintsonkothileyo zesandwich kunye nezakhiwo eziqinisiweyo, ukugcinwa kwezinto kunye nokugcinwa kwabasebenzi kubaluleke ngakumbi.Ngokomzekelo, ekwenziweni kwee-rudders ezithe nkqo kwishishini leenqwelomoya, iindleko zokunciphisa i-fasteners nge-365 ziyancipha nge-75% xa kuthelekiswa nendlela yendabuko, ubunzima bemveliso buhlala bungatshintshi, kwaye ukusebenza kungcono.
(7) Ukuchaneka kwemveliso kulungile.Ukuchaneka komgangatho (ubukhulu) bemveliso yenkqubo yokuqaliswa kwe-vacuum resin ingcono kuneemveliso zokubeka izandla.Ngaphantsi kolwaleko olufanayo, ubukhulu beemveliso zetekhnoloji ye-vacuum vacuum diffusion yi-2/3 yaleyo yeemveliso zokubekwa kwezandla.Ukutenxa kobukhulu bemveliso kumalunga ne-±10%, ngelixa inkqubo yokubekwa kwezandla iqhele ukuba yi-±20%.Ukuthe tyaba komphezulu wemveliso kubhetele kuneemveliso zokubeka izandla.Udonga lwangaphakathi lwemveliso ye-hood yenkqubo yokungeniswa kwe-vacuum resin ilula, kwaye umphezulu ngokwemvelo wenza i-resin-rich-rich layer, engadingi isambatho esongezelelweyo esiphezulu.Ukuncitshiswa kwabasebenzi kunye nezixhobo zesanti kunye neenkqubo zokupeyinta.
Ewe kunjalo, inkqubo yangoku yokwazisa i-vacuum resin ineziphene ezithile:
(1) Inkqubo yokulungiselela ithatha ixesha elide kwaye inzima ngakumbi.Ukucwangciswa okufanelekileyo, ukubekwa kweendaba zokuguqula, iityhubhu zokuguqula, ukutywinwa okusebenzayo kwe-vacuum, njl.Ngoko ke, kwiimveliso ezincinci, ixesha lenkqubo lide kunenkqubo yokubeka isandla.
(2) Iindleko zemveliso ziphezulu kwaye inkunkuma eninzi yenziwa.Izixhobo ezincedisayo ezifana nefilimu ye-vacuum bag, i-diversion medium, ilaphu lokukhulula kunye netyhubhu yokuguqula zonke ziyalahlwa, kwaye ezininzi zazo zithunyelwa ngaphandle, ngoko ke iindleko zemveliso ziphezulu kunenkqubo yokubeka isandla.Kodwa imveliso enkulu, incinci umahluko.Ngokufakwa kwendawo yezinto ezincedisayo, lo mahluko weendleko uya usiba mncinci kwaye uncinci.Uphando lwangoku kwizinto ezincedisayo ezinokuthi zisetyenziswe ngamaxesha amaninzi lukhokelo lophuhliso lwale nkqubo.
(3) Ukwenziwa kwenkqubo kunemingcipheko ethile.Ngokukodwa kwiimveliso ezinkulu kunye nezakhiwo eziyinkimbinkimbi, emva kokuba i-resin infusion ingaphumeleli, imveliso ilula ukuchithwa.
Ngoko ke, uphando olungcono lwangaphambili, ulawulo olungqongqo lwenkqubo kunye namanyathelo okulungisa asebenzayo afunekayo ukuze kuqinisekiswe impumelelo yenkqubo.
