I-Fiberglass Surface Veil: Oko Ikwenzayo kunye nendlela yokukhetha ubunzima obufanelekileyo be-GSM kwiiprojekthi ze-FRP

Ukuba wakha waxelelwa ukuba isigqubuthelo somphezulu "siyinto yokuzikhethela" - okanye, kwelinye icala, ukuba siya kutshintsha amandla e-laminate yakho - zombini ezi zivakalisi azichazi ukuba lo maleko ubhityileyo nonwoven wenzelwe ntoni ngokwenene. Isigqubuthelo somphezulu we-fiberglass (esithengiswa njengezicubu zomphezulu okanye imathi yokugquma) sisixhobo esisebenzayo, asilo maleko wokuqinisa. Senza imisebenzi emithathu ethile kumphezulu wenxalenye ye-FRP, asenzeli msebenzi wokuthwala umthwalo we-strand mat eqoshiweyo okanye ukuzulazula okulukiweyo, kwaye ukwazi ukuba nguwuphi umsebenzi owufunayo kukuxelela ukuba loluphi ubunzima kunye noluhlu lwemveliso omawu-odole. Esi sikhokelo sihamba ngaloo misebenzi, uluhlu lobunzima olubandakanyekayo, kunye nemibuzo ekufuneka uyiphendule ngaphambi kokuba ubeke i-RFQ.

Isigqubuthelo Somphezulu We-Fiberglass: Oko Sikwenzayo Nendlela Yokukhetha Ubunzima Obufanelekileyo

Isigqubuthelo somphezulu sisixhobo esenziwe ngemicu yeglasi ecolekileyo kakhulu — iiRuifiber zitsalwa kwii-microns eziyi-3.5–6 — zibanjwe kwisixhobo sokukhanyisa, esinobunzima obuphakathi kwama-20 nama-90 g/m². Oko kukhaphukhaphu kakhulu kunesixhobo somtya esinqunqiweyo kunye neeleya ezilukiweyo ezingaphantsi kwaso, kwaye oko kukhaphukhaphu yeyona nto ibalulekileyo: asikho apho ukuze songeze amandla, sikhona apho ukuze silawule ukuba umphezulu wenxalenye yakho ujongeka njani kwaye uziphatha njani. Imisebenzi emithathu igubungela phantse yonke into esetyenziswayo.

Umsebenzi 1: fihla ubume bokuqinisa.Iifayibha ezirhabaxa ezivela kwiileya ezingezantsi zidla ngoku "printa" ijazi lejeli okanye i-topcoat, zishiya iphethini elukiweyo okanye ephothiweyo kumphezulu ogqityiweyo. Umaleko weveyili ugcwala i-resin kwaye wenze i-stratum encinci, etyebileyo kwifayibha, etyebileyo kwi-resin egquma loo texture, ukuze ubuso obugqityiweyo bufundeke buthambile kwaye buhambelana. Xa lo msebenzi ungafakwanga okanye i-veyili ilula kakhulu kunetexture engaphantsi, uyayibona: iipatheni ze-ghost kwi-gel coat emva kokuyicoca okanye ukuyicoca.

Umsebenzi 2: xhasa umqobo wokugqwala.Kwiitanki, iipayipi kunye nee-linings, ukumelana nokugqwala kwale nxalenye akuveli kwi-veil ngokwayo — kuvela kwinkqubo ye-resin. Into eyenziwa yi-veil kukuthwala nokuxhasa i-liner yangaphakathi etyebileyo kwi-resin: iifayibha ezincinci zibamba i-resin eninzi ngokungaqhelekanga kumphezulu, zinika umaleko womqobo weekhemikhali ubukhulu kunye nokuthembeka okufunekayo. Iprofayili yokumelana okusebenzayo igqitywa yi-resin oyidibanisa nayo. Xa lo msebenzi wenziwe kakubi, ukudumba kunye nokuqhekeka kwe-liner kwangoko ebusweni beekhemikhali ziimpawu eziqhelekileyo.

Umsebenzi 3: ukuzinzisa imveliso.Kwimigca ye-pultrusion nakwimisebenzi yokubumba ephindaphindwayo, isigqubuthelo kumphezulu ongaphandle sinika inkqubo umphezulu ohambelanayo, onokuqikelelwa ukuba usebenze kuwo: sinciphisa imicu yesakhiwo eveziweyo kwiiprofayili ze-pultruded, kwaye senza umgangatho womphezulu uphindaphindeke ukusuka kwibhetshi ukuya kwenye kunokuxhomekeka kwindlela umqhubi wokugqibela abeke ngayo imathi. Xa umphezulu wemveliso ungangqinelani, uphawu lukwahluka phakathi kwamacandelo abunjwe ngendlela efanayo.

Oko INGAKWENZIYO

Iingcaciso ezimbini zigcina abathengi imali yokwenene, kuba zombini ezi ngcamango ziphosakeleyo zikhokelela ekuthengeni gwenxa.

Ayithwali mthwalo wesakhiwo.Isigqubuthelo esingama-30 g/m² asincedi nganto ekuqineni okanye ekuqineni kwe-laminate; ulwakhiwo luvela kwiileya ezinqunqiweyo nezilukiweyo. Kuluhlu lwethu lwemveliso sichaza isigqubuthelo somphezulu njengesinegalelo kumgangatho womphezulu, ukhuseleko lokugqwala kunye nokuqina kwenxalenye egqityiweyo - funda oko njengoncedo ekuqineni komphezulu, kungekhona njengokuqinisa ulwakhiwo. Ukuba i-laminate idinga amandla, impendulo yi-CSM ebekwe ngcono okanye engcono kunye nokuzula okulukiweyo, kungekhona isigqubuthelo esinzima. (Ukuba ukhetha phakathi kwezo leya zesakhiwo, jonga isikhokelo sethu kwi-strand mat enqunqiweyo vs ukuzula okulukiweyo.)

Ayiyenzi i-laminate imelane neekhemikhali.Le yeyona ndlela ixhaphakileyo yokuthembisa kakhulu. Ikhuselo lixhasa umaleko otyebileyo kwi-resin apho kuhlala khona ukumelana neekhemikhali; ukumelana kwenyani nekhemikhali yakho ethile, kubushushu bakho obuthile, yipropathi yenkqubo ye-resin kunye noyilo lulonke. Ikhuselo elichazwe ngokuchanekileyo lisangasebenzi ukuba i-resin engasemva kwayo ayilunganga kwimidiya.

Kukwakho nemeko efanelekileyo yokuyitsiba. Apho ubuso bungabonakali, bungacinywanga, kwaye bungathwali khemikhali — umva wephaneli, iflange yangaphakathi, ubambo olufihlakeleyo lwesakhiwo — isigqubuthelo songeza iindleko zezinto kunye nenyathelo lokubeka ngaphandle kokongeza nantoni na efunekayo kwinxalenye. Imo yokusilela ayikokusebenzisa isigqubuthelo; kukusebenzisa esinye ngokwesiqhelo ebusweni apho kungekho misebenzi yaso mithathu isebenza khona, okanye ukusishiya ebusweni apho omnye wabo wenza njalo. Hlola ubuso ngabunye benxalenye ngokwemisebenzi emithathu engentla uze uvumele oko kugqibe.

Iveyili vs imathi yentambo enqunqiweyo

Ngenxa yokuba zombini zii-random-fiber mats, ezi zimbini ziyabhideka. Umahluko bubunzima kunye nendima:

	Isigqubuthelo somphezulu	Imathi enqunqiweyo yentambo
Ubunzima	20–90 g/m²	100–900 g/m²
Ubunono befayibha	intle kakhulu (3.5–6 μm kuluhlu lweRuifiber)	imicu enqunqiweyo
Indima	umsebenzi womphezulu: ukugudileyo, inkxaso yeliner, uzinzo lwenkqubo	ukusasazwa kwenqwaba kunye nokuqinisa
Isikhundla	ubuso (ubuso) bangaphandle, ngokuqhelekileyo ngokuchasene nomngundo okanye imidiya	umbindi we-laminate

Inqaku lesigama: abathengisi basebenzisa "isigqubuthelo somphezulu", "isicwili somphezulu" kunye "nomata womphezulu" ngokulula kuhlobo olufanayo lwemveliso. Thelekisa ngesakhiwo nobunzima, kungekhona ngegama.

Ezi mveliso zimbini zizinto ezongezelelweyo, azizo ezinye iindlela: i-corrosion liner eqhelekileyo ifaka i-gel coat, emva koko ibe yi-veil, emva kokoI-CSMii-plies — isigqubuthelo sibonelela ngomsebenzi womphezulu ngelixa i-CSM yakha ubukhulu kunye namandla.

Ukukhetha ubunzima

IiRuifiber'suluhlu lwesigqubuthelo somphezuluIsebenza ukusuka kwi-20 ukuya kwi-90 g/m², ngokwee-series ezenzelwe ukubekwa ngesandla, ukujijwa kwe-filament kunye ne-pultrusion. Ngaphakathi kolo luhlu, amashishini aqokelela ubunzima ngokusebenzisa ngolu hlobo (le yindlela eqhelekileyo kubaboneleli, hayi iphepha ledatha elithile le-Ruifiber - qinisekisa ukhetho lokugqibela nomthengisi wakho):

Ibhendi yobunzima	Umlinganiswa oqhelekileyo	Ifaneleka xa
~20 g/m²	elula kakhulu, ehambelanayo kakhulu	iimolds ezintsonkothileyo okanye ezigobileyo apho isigqubuthelo kufuneka silandele imilo
~30 g/m²	ibhendi ephakathi yenjongo ngokubanzi	uninzi lweendawo zokuhombisa kunye nomsebenzi oqhelekileyo we-liner; indawo eqhelekileyo yokuqala
~50 g/m² nangaphezulu	umaleko otyebileyo we-resin	ubuso obunzima beekhemikhali kunye neendawo ezifuna umaleko okhuselekileyo oqinileyo

Imiqondiso emithathu ikukhuthaza ukuba unyuke ngebhanti enye: i-chemical media enamandla ebusweni obusebenzayo, ubume obuqinileyo obungaphantsi kwesigqubuthelo esikhanyayo esingayi kufihla, kunye neendawo ezithe tyaba okanye ezivulekileyo apho ukuhambelana kwazo kungabalulekile. Ezimbini zikudonsa phantsi: i-radii eqinileyo kunye neenkcukacha ze-mold, kunye neendawo zokuhombisa apho ufuna ubukho be-fiber encinci ebusweni.

Inqaku elinye elisebenzayo malunga nokuphatha: ubunzima obukhaphukhaphu buthambile. Isembozo se-20 g/m² sikrazuka lula kakhulu ngexesha lokusika nokubeka kunesembozo se-50 g/m², ngoko ke thenga iisembozo ezintsha ngamanye amaxesha zibe nzima "ukuze zikhuseleke" kwaye emva koko zifumanise ukuba umaleko onzima kunzima ukuwulandela. Ukuba iqela lakho liphatha izinto okokuqala, kufanelekile uku-odola ubungakanani obuncinci beesimbozo ezibini ezikufutshane uze uzisebenzise kwiphaneli yovavanyo ngaphambi kokuba wenze i-odolo epheleleyo.

Ukukha ngokwenkqubo: ukubeka ngesandla, ukujija, ukugquma

Kulapho uthotho lweemveliso zomthengisi lubaluleke khona ngaphezu kwephepha ledatha eliqhelekileyo. I-Ruifiber yahlula isigqubuthelo sayo somphezulu sibe ziinxalenye ezintathu ukuze ihambelane neenkqubo ezintathu ezisetyenziswa kakhulu ngabathengi:

Uthotho	Yenzelwe	Yintoni eyenziwa sisigqubuthelo apho
Ukubeka isandla phezulu	ukubumbana koqhagamshelwano nxamnye nomphezulu wokubumba	isebenza njengesikhumba phezu kwejeli, ilungisa ubume bayo kwaye yakha i-liner
Ukujika kwefilament	iindawo ezisilinda — imibhobho, iitanki, iinqanawa	isonga njengenxalenye yolandelelwano lwe-liner kumphezulu ojongene nemidiya
Ukuphambuka	iiprofayili eziqhubekayo	ijikelezwe kwiprofayili ngaphambi kokuba ifile; inyangeka ibe lusu olungaphandle oluthambileyo olunemicu embalwa engabonakaliyo — exhaphakileyo kwii-engile, kwiitshaneli, kwiintonga, nakwizinto zeleli

Inqaku malunga nokhetho lwe-polyester veil: I-Ruifiber ikwabonelela ngenguqulelo ye-polyester kumgca wayo we-veil combo stitch mat; inguqulelo ye-fiberglass ibekwe kwiindawo ezifuna ukubambezeleka okukhulu komlilo kunye nokumelana nobushushu kune-polyester variant. Kwizinto ezithengiweyo ze-surface-veil, iglasi yeyona iqhelekileyo; buza nge-polyester kuphela ukuba isicelo sakho sifuna yona ngokukodwa.

Yintoni ekufuneka uyiqinisekise ngaphambi kokuba u-odole

I-RFQ yesigqubuthelo somphezulu efumana ikowuteshini enye ecocekileyo endaweni yemijikelo emithathu yokucacisa iqulethe amasimi amahlanu:

1. Indima yelaminate— ubuso bobuhle, i-corrosion liner, ubuso obutshintsha umbala, okanye i-process stabilizer. Oku kuqhuba yonke enye into.
2.Ubunzima nobubanzi— umz. 30 g/m², iiroli eziyi-1,000 mm. Nika uluhlu kunye nolindelo lokunyamezela endaweni yenani elinye ukuba uguquguqukayo.
3. Ukuhambelana kweBinder ne-resin yakho— i-binder kufuneka inyibilike ngokuchanekileyo kwinkqubo yakho ye-resin (i-polyester, i-vinyl ester, i-epoxy). Xelela umthengisi i-resin; mcele ukuba afane ne-binder.
4. Inkqubo— ukubeka ngesandla, ukujija okanye ukuphamba, ukuze ucatshulwe uthotho olufanelekileyo.
5. Uvavanyo lwekhemistri yeglasi kunye nokwamkelwa— buza ukuba ikhuselo lithathwe koluphi uhlobo lweglasi kwaye loluphi uvavanyo oluzayo onokuluchaza (ubunzima kwindawo nganye, ukunyibilika kwebhanti).

FAQ

Ingaba isigqubuthelo somphezulu senziwe ngendlela ethile?

Hayi. Inegalelo ekuqineni nasekusemgangathweni komphezulu, kodwa amandla olwakhiwo avela kwiileya zokuqinisa ezinqunqiweyo nezilukiweyo kwi-laminate.

Ngaba isigqubuthelo somphezulu senza i-laminate yam ingangeni kwiikhemikhali?

Hayi — ukumelana neekhemikhali yimpawu yenkqubo ye-resin kunye noyilo lulonke. Ikhuselo lixhasa umaleko we-liner otyebileyo kwi-resin apho olo xhathiso lufumaneka khona.

Iglasi okanye isigqubuthelo sepolyester?

Kwiinkqubo ezininzi ze-surface-veil, iglasi yeyona imiselweyo, kwaye iRuifiber ibeka inguqulelo yayo ye-fiberglass veil ukuze ikwazi ukumelana nomlilo kunye nokumelana nobushushu ngaphezu kwe-polyester variant kumgca wayo we-combo stitch mat. Cacisa i-polyester kuphela apho isicelo sakho sifuna khona.

Khetha isigqubuthelo sakho ucinga ngenkqubo

Eyona ndlela ikhawulezayo yokufumana iinkcukacha ezichanekileyo zesigqubuthelo somphezulu kukubiza inkqubo kunye nendima kuqala - emva koko ubunzima kunye nobubanzi kulandela.Khangela iimveliso zokuqinisa i-fiberglass zeRuifiberukuze sibone ukubekwa kwesandla, ukujija kwentambo kunye nothotho lweveyili ye-pultrusion, okanye uthumele i-RFQ enamabala amahlanu angasentla size sibuye nothotho oluhambelanayo.
