1. Ukubunjwa Kwezandla

Ukubunjwa kokubekwa kwezandla kuyindlela evamile kakhulu yokwenza amaflange epulasitiki enziwe nge-fiberglass (FRP). Le nqubo ihilela ukubeka ngesandla i-resin-impregnatedindwangu ye-fiberglassnoma amacansi abe isikhunta futhi ubavumele ukuba belaphe. Inqubo ethize imi kanje: Okokuqala, ungqimba lwangaphakathi olune-resin olucebile lwenziwa kusetshenziswa indwangu ye-resin ne-fiberglass. Ngemva kokuphulukiswa kongqimba lwe-liner, lususwa esikhunjeni, futhi ungqimba lwesakhiwo lwakhiwe. I-resin bese ixutshwa kukho kokubili indawo yokubunjwa kanye ne-liner yangaphakathi. Izendlalelo zendwangu ye-fiberglass ezisikwe ngaphambili zendlalwa ngokohlelo lokunqwabelanisa olunqunywe kusengaphambili, ungqimba ngalunye luhlanganiswe kusetshenziswa i-roller ukuze kuqinisekiswe ukufakwa okuphelele. Lapho ukuqina okufunayo kufinyelelwa, umhlangano uyaphulukiswa futhi udilizwe.

I-matrix resin yokubunjwa kokubekwa kwezandla ngokuvamile isebenzisa i-epoxy noma i-polyester engagcwele, kuyilapho into eqinisayo iyi-alkali emaphakathi nomaIndwangu ye-fiberglass engena-alkali.

Izinzuzo: Izidingo zemishini ephansi, ikhono lokukhiqiza ama-flange angajwayelekile, futhi akukho mingcele ku-flange geometry.

Ukungalungi: Amabhamuza omoya akhiwe ngesikhathi sokuphulukiswa kwe-resin angaholela ku-porosity, ukunciphisa amandla omshini; ukusebenza kahle kokukhiqiza okuphansi; kanye nesiphetho esingalingani, esingacolisisiwe.

2. Ukubunjwa Kokucindezela

Ukubumba ukucindezela kuhilela ukubeka inani elilinganisiwe lezinto zokubumba zibe isikhunta se-flange bese ukwelapha ngaphansi kwengcindezi usebenzisa umshini wokunyathelisa. Izinto zokubumba ziyahlukahluka futhi zingabandakanya izinhlanganisela zefayibha eziyisinqamuleli ezixutshwe ngaphambili noma ezifakwe ngaphambili, izinsalela zendwangu ye-fiberglass egaywe kabusha, izindandatho/imicu yendwangu yengilazi enezingqimba eziningi, amashidi e-SMC astakiwe (inhlanganisela yokubumba amashidi), noma amapreforms endwangu ye-fiberglass eselukiwe ngaphambilini. Kule ndlela, i-flange disk nentamo ibunjwa kanyekanye, ithuthukisa amandla ahlangene kanye nobuqotho besakhiwo jikelele.

Izinzuzo: Ukunemba okuphezulu kwe-dimensional, ukuphindaphinda, ukufaneleka kokukhiqizwa kwenqwaba okuzenzakalelayo, ikhono lokwenza ama-flange entamo e-tapered esinyathelweni esisodwa, kanye nezindawo ezibushelelezi zobuhle ezingadingi ukucutshungulwa ngemuva.

Ukungalungi: Izindleko zesikhunta eziphezulu kanye nemikhawulo kusayizi we-flange ngenxa yemikhawulo yombhede wokucindezela.

3. I-Resin Transfer Molding (RTM)  

I-RTM ihlanganisa ukubeka i-fiberglass eqinisayo esikhunjeni esivaliwe, ukujova i-resin ukuze kukhule imicu, kanye nokwelapha. Inqubo ihlanganisa:

• Ukubeka i-fiberglass preform ehambisana ne-flange geometry emgodini wesikhunta.
• Ukujova i-low-viscosity resin ngaphansi kwezinga lokushisa elilawulwayo kanye nengcindezi ukuze ugcwalise i-preform futhi ukhiphe umoya.
• Ukushisa ukuphulukisa nokudiliza i-flange eqediwe.

Ama-resin ngokuvamile ayi-polyester engasetshenzisiwe noma i-epoxy, kuyilapho ukuqinisa kufaka phakathiamacansi e-fiberglass aqhubekayonoma izindwangu ezilukiwe. Izigcwalisi ezifana ne-calcium carbonate, i-mica, noma i-aluminium hydroxide ingase yengezwe ukuze kuthuthukiswe izakhiwo noma kwehliswe izindleko.

Izinzuzo: Indawo ebushelelezi, ukukhiqiza okuphezulu, ukusebenza kwesikhunta esivaliwe (ukunciphisa ukukhishwa kwegesi nobungozi bezempilo), ukuqondanisa i-fiber eqondisayo ukuze uthole amandla athuthukisiwe, ukutshalwa kwezimali okuncane, kanye nokuncipha kokusetshenziswa kwempahla/amandla.

4. I-Vacuum-Assisted Resin Transfer Molding (VARTM)

I-VARTM ilungisa i-RTM ngokujova i-resin ngaphansi kwe-vacuum. Le nqubo ihlanganisa ukuvala i-fiberglass preform esikhunjeni sowesilisa ngesikhwama se-vacuum, ukukhipha umoya endaweni yesikhunta, nokudonsa inhlaka ku-preform ngokusebenzisa ingcindezi ye-vacuum.

Uma kuqhathaniswa ne-RTM, i-VARTM ikhiqiza ama-flange ane-porosity ephansi, okuqukethwe kwe-fiber ephakeme, namandla aphakeme wemishini.

5. Ukubunjwa kokudlulisa inhlaka okusizwa yi-Airbag

Ukubumba kwe-RTM okusizwa nge-Airbag nakho kuwuhlobo lobuchwepheshe bokubumba obuthuthukiswe ngesisekelo se-RTM. Inqubo yokulungisa ama-flange ngale ndlela yokubumba imi kanje: i-fiber preform yengilazi emise okwe-flange ibekwe phezu kwe-airbag, egcwele umoya bese inwebeka ngaphandle futhi ivalwe endaweni yesikhunta se-cathode, kanye ne-flange preform phakathi kwesikhunta se-cathode kanye ne-airbag ihlanganiswe futhi ilashwe.

Izinzuzo: ukunwetshwa kwe-airbag kungenza i-resin igeleze engxenyeni ye-preform engafakwanga, iqinisekise ukuthi i-preform ifakwe kahle yi-resin; okuqukethwe kwe-resin kungalungiswa ngokucindezela kwe-airbag; ukucindezela okwenziwa yi-airbag kusetshenziselwa indawo yangaphakathi ye-flange, futhi i-flange ngemva kokuphulukisa ine-porosity ephansi kanye nezakhiwo ezinhle zemishini. Ngokuvamile, ngemva kokulungiselelaI-FRPi-flange ngendlela yokubumba engenhla, indawo yangaphandle ye-flange kufanele futhi icutshungulwe ngokuvumelana nezidingo zokusetshenziswa kokuphenduka nokubhoboza emigodini ezungeze umjikelezo we-flange.
