1. Ukubumba Ngesandla

Ukubumba ngesandla kuyindlela evamile kakhulu yokwenza ama-flange epulasitiki aqiniswe nge-fiberglass (FRP). Le ndlela ihilela ukufaka ngesandla ama-resin-impregnatedindwangu ye-fiberglassnoma ama-mat abe yisikhunta bese evumela ukuthi siphilise. Inqubo ethile yile: Okokuqala, kwenziwa ungqimba lwangaphakathi olucebile nge-resin kusetshenziswa indwangu ye-resin ne-fiberglass. Ngemva kokuba ungqimba lwangaphakathi selupholile, luyasuswa kusikhunta, bese kwakhiwa ungqimba lwesakhiwo. I-resin ibe isixutshwa ebusweni besikhunta kanye ne-liner yangaphakathi. Izendlalelo zendwangu ye-fiberglass ezisikiwe ngaphambilini zibekwa ngokwecebo lokuhlanganisa elinqunyiwe, kanti ungqimba ngalunye luqiniswe kusetshenziswa i-roller ukuqinisekisa ukufakwa kahle. Uma ubukhulu obufunekayo sebufinyelelwe, ukuhlanganiswa kuyaphiliswa futhi kususwe.

I-resin ye-matrix yokubumba ngesandla ngokuvamile isebenzisa i-epoxy noma i-polyester engagcwali, kuyilapho izinto zokuqinisa ziyi-alkali ephakathi nomaindwangu ye-fiberglass engena-alkali.

Izinzuzo: Izidingo eziphansi zemishini, ikhono lokukhiqiza ama-flange angewona ajwayelekile, futhi akukho mingcele ku-geometry ye-flange.

Okubi: Amabhamuza omoya akheka ngesikhathi sokulungiswa kwe-resin angaholela ekuqhekekeni, anciphise amandla omshini; ukusebenza kahle kokukhiqiza okuphansi; kanye nokuphela kobuso okungalingani, okungacolisisiwe.

2. Ukubumba Kokucindezela

Ukubumba ngokucindezela kuhilela ukubeka inani elilinganisiwe lezinto zokubumba ku-flange mold bese uyilungisa ngaphansi kwengcindezi usebenzisa umshini wokunyathelisa. Izinto zokubumba ziyahlukahluka futhi zingafaka phakathi ama-fiber compounds ahlanganisiwe noma afakwe kusengaphambili, izingcezu zendwangu ye-fiberglass ephinde yasetshenziswa, amasongo/imicu yendwangu ye-fiberglass enezingqimba eziningi ezifakwe i-resin, amashidi e-SMC (sheet molding compound), noma ama-preforms endwangu ye-fiberglass ehlanganisiwe. Ngale ndlela, idiski ye-flange kanye nentamo kuyabunjwa ngesikhathi esisodwa, kuthuthukisa amandla amalunga kanye nobuqotho besakhiwo sonke.

Izinzuzo: Ukunemba okuphezulu, ukuphindaphindwa, ukufaneleka kokukhiqizwa ngobuningi okuzenzakalelayo, ikhono lokwenza ama-flange ayinkimbinkimbi anentamo ethambile ngesinyathelo esisodwa, kanye nezindawo ezibushelelezi ngobuhle ezingadingi ukucutshungulwa ngemuva.

Okubi: Izindleko eziphezulu zesikhunta kanye nemikhawulo ngobukhulu be-flange ngenxa yemingcele yombhede wokucindezela.

3. Ukubumba Ukudluliselwa Kwe-Resin (RTM)  

I-RTM ihilela ukufaka i-fiberglass reinforcement esikhumbeni esivaliwe, ukufaka i-resin ukuze ifake imicu, kanye nokulungisa. Inqubo ihlanganisa:

• Ukubeka i-preform ye-fiberglass ehambisana ne-geometry ye-flange emgodini wesikhunta.
• Ukufaka i-resin ene-viscosity ephansi ngaphansi kokushisa okulawulwayo kanye nengcindezi ukuze kugcwaliswe i-preform futhi kususwe umoya.
• Ukushisa ukuze kulungiswe futhi kususwe i-flange esiqediwe.

Ama-resin ngokuvamile ayi-polyester engagcwele noma i-epoxy, kuyilapho ukuqinisa kufaka phakathiomata abaqhubekayo be-fiberglassnoma izindwangu ezilukiwe. Izithako zokugcwalisa ezifana ne-calcium carbonate, i-mica, noma i-aluminium hydroxide zingangezwa ukuze kuthuthukiswe izakhiwo noma kuncishiswe izindleko.

Izinzuzo: Izindawo ezibushelelezi, umkhiqizo ophezulu, ukusebenza kwesikhunta esivaliwe (ukunciphisa ukukhishwa kwegesi kanye nezingozi zempilo), ukuvumelanisa ifayibha ngendlela eqondile ukuze kube namandla athuthukisiwe, ukutshalwa kwezimali okuphansi, kanye nokusetshenziswa kwezinto/amandla okuncishisiwe.

4. Ukubumba Okusizwa Yi-Vacuum Resin Transfer Molding (VARTM)

I-VARTM ishintsha i-RTM ngokufaka i-resin ngaphansi kwe-vacuum. Le nqubo ihilela ukuvala i-preform ye-fiberglass ku-mold yesilisa ngesikhwama se-vacuum, ukukhipha umoya emgodini we-mold, nokudonsa i-resin ku-preform nge-vacuum pressure.

Uma kuqhathaniswa ne-RTM, i-VARTM ikhiqiza ama-flange ane-porosity ephansi, okuqukethwe okuphezulu kwefayibha, kanye namandla aphezulu okusebenza.

5. Ukubumba kokudlulisa i-resin okusizwa yi-Airbag

Ukubumba i-RTM okusizwa yi-Airbag nakho kuyindlela yobuchwepheshe bokubumba obuthuthukiswe ngesisekelo se-RTM. Inqubo yokulungiselela ama-flange ngale ndlela yokubumba imi kanje: i-preform yengilazi yefayibha emise okwe-flange ibekwa ebusweni be-airbag, egcwala umoya bese inwebeka ngaphandle bese ivalelwa esikhaleni se-cathode mold, bese i-preform ye-flange ephakathi kwe-cathode mold ne-airbag iyaqiniswa futhi iphole.

Izinzuzo: ukunwetshwa kwesikhwama somoya kungenza i-resin igeleze iye engxenyeni ye-preform engakafakwanga, okuqinisekisa ukuthi i-preform ifakwa kahle yi-resin; okuqukethwe kwe-resin kungalungiswa ngokucindezela kwesikhwama somoya; ukucindezela okukhishwa yisikhwama somoya kufakwa ebusweni bangaphakathi be-flange, kanti i-flange ngemva kokuqina inezimbobo ezincane kanye nezakhiwo ezinhle zemishini. Ngokuvamile, ngemva kokulungiselelaI-FRPi-flange ngendlela yokubumba engenhla, ubuso bangaphandle be-flange kufanele futhi bucutshungulwe ngokwezidingo zokusebenzisa ukujika nokubhoboza imigodi ezungeze umjikelezo we-flange.
