1. Ukubunjwa kwezandla

Ukubunjwa kokubekwa kwezandla yeyona ndlela yemveli yokwenza iiflange zeplastiki yefiberglass-reinforced (FRP). Obu buchule bubandakanya ukubeka ngesandla i-resin-impregnatedilaphu lefiberglassokanye iimethi zibe ngundo kwaye zivumele ukuba zinyange. Inkqubo ethile yile ilandelayo: Okokuqala, i-resin-rich-rich liner layer yenziwa kusetyenziswa i-resin kunye ne-fiberglass cloth. Emva kokuba i-liner layer iphilisa, ikhutshwe kwi-mold, kwaye i-structural layer yakhiwe. Iresin ke igalelwe kumphezulu wokungunda kunye nelayini yangaphakathi. Ilaphu lelaphu le-fiberglass elisikwe kwangaphambili libekwe ngokweplani yokupakishwa kwangaphambili, kunye nomaleko ngamnye odityanisiweyo kusetyenziswa i-roller ukuqinisekisa ukufakwa ngokucokisekileyo. Emva kokuba ubukhulu obufunwayo bufezekisiwe, indibano iyaphiliswa kwaye idilizwe.

I-matrix yeresin yokubunjwa kokubeka izandla ngokuqhelekileyo isebenzisa i-epoxy okanye i-polyester engaxutywanga, ngelixa imathiriyeli yokuqinisa iphakathi-alkali okanyeilaphu le-alkali-free fiberglass.

Izinto eziluncedo: Iimfuno zezixhobo eziphantsi, ukukwazi ukuvelisa iiflange ezingekho mgangathweni, kwaye akukho zithintelo kwijometri yeflange.

Ukungalungi: Iibhubhu zomoya ezenziwe ngexesha lokunyanga i-resin zingakhokelela kwi-porosity, ukunciphisa amandla omatshini; ukusebenza kwemveliso ephantsi; kunye nomgangatho ongalinganiyo, ongacocwanga.

2. Ukubunjwa koxinzelelo

Ukubunjwa koxinzelelo kubandakanya ukubeka umlinganiselo olinganisiweyo wezinto zokubumba kwi-flange mold kunye nokunyanga phantsi koxinzelelo usebenzisa i-press. Izinto zokubumba ziyahluka kwaye zinokubandakanya iikhompawundi zefayibha ezixutywe kwangaphambili okanye ezifakwe ngaphambili ezifakwe ngaphambili, i-fiberglass elaphu elisetyenzisiweyo elisetyenzisiweyo, i-resin-impregnated multi-layer fiberglass cloth rings/strips, stacked SMC (sheet compound compound), okanye preforms prewoven fiberglass fabric preforms. Kule ndlela, i-flange disk kunye nentamo ibunjwe ngaxeshanye, iphucula amandla adibeneyo kunye nokunyaniseka kwesakhiwo.

Izinto eziluncedo: Ukuchaneka okuphezulu komgangatho, ukuphinda-phinda, ukufaneleka kwemveliso yobuninzi ezenzekelayo, ukukwazi ukwenza iiflange ezintsonkothileyo zentanyeni kwinqanaba elinye, kunye neendawo ezigudileyo ezinobuhle ezingafuneki emva kokulungiswa.

Ukungalungi: Iindleko eziphezulu zokungunda kunye nezithintelo kwisayizi yeflange ngenxa yokunyanzeliswa kwebhedi.

3. Ukubunjwa kweResin Transfer Molding (RTM)  

I-RTM ibandakanya ukubeka i-fiberglass ukuqiniswa kwi-mold evaliweyo, i-resin yokufaka i-resin yokufaka i-fibers, kunye nokunyanga. Inkqubo ibandakanya:

• Ukubeka i-fiberglass preform ehambelana nejometri yeflange kumgodi wokungunda.
• Ukutofa i-resin ephantsi ye-viscosity phantsi kweqondo lokushisa elilawulwayo kunye noxinzelelo lokugcwalisa i-preform kunye nokususa umoya.
• Ukufudumala ukunyanga kunye nokudiliza i-flange egqityiweyo.

Iiresin ngokuqhelekileyo ziyi-polyester engaxutywanga okanye i-epoxy, ngelixa ukuqinisa kubandakanyaiimethi zefiberglass eziqhubekayookanye amalaphu alukiweyo. Izihluzi ezifana ne-calcium carbonate, i-mica, okanye i-aluminium hydroxide inokongezwa ukuphucula iipropati okanye ukunciphisa iindleko.

Izinto eziluncedo: Imiphezulu egudileyo, imveliso ephezulu, ukusebenza kwe-mold evaliweyo (ukunciphisa ukukhutshwa kunye nobungozi bezempilo), ukulungelelaniswa kwefayibha yolwalathiso ukuze kuqiniswe amandla, utyalo-mali oluphantsi, kunye nokunciphisa ukusetyenziswa kwezinto / amandla.

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

I-VARTM iguqula i-RTM ngokufaka i-resin phantsi kwe-vacuum. Le nkqubo ibandakanya ukutywina i-fiberglass preform kwi-mold yendoda kunye nebhegi yokucoca, ukukhupha umoya kumgodi wokungunda, kunye nokuzoba iresin kwi-preform ngoxinzelelo lwevacuum.

Xa kuthelekiswa ne-RTM, i-VAR TM ivelisa i-flanges ene-porosity ephantsi, i-fiber content content, kunye namandla aphezulu omatshini.

5. I-Airbag-incedise ukubunjwa kwe-resin transfer

Ukubumba i-RTM encediswa yi-Airbag ikwaluhlobo lobuchwephesha bokubumba obuphuhliswe kwisiseko se-RTM. Inkqubo yokulungiselela iiflange ngale ndlela yokubumba yile ndlela ilandelayo: i-flange-shaped glass fiber preform ibekwe phezu kwe-airbag, ezaliswe ngumoya kwaye yandisa ngaphandle kwaye ivalwe kwisithuba se-cathode mold, kunye ne-flange preform phakathi kwe-cathode mold kunye ne-airbag ihlanganiswe kwaye iphiliswe.

Izinto eziluncedo: ukwandiswa kwe-airbag kunokwenza i-resin ihambe ukuya kwindawo ye-preform engazange ifakwe, iqinisekisa ukuba i-preform ifakwe kakuhle yi-resin; umxholo we-resin unokulungiswa ngoxinzelelo lwe-airbag; uxinzelelo olwenziwa yi-airbag lusetyenziswe kwindawo yangaphakathi ye-flange, kwaye i-flange emva kokunyanga ine-porosity ephantsi kunye neempawu ezintle zomatshini. Ngokuqhelekileyo, emva kokulungiselelaFRPi-flange kunye nendlela yokubumba engentla, umphezulu wangaphandle we-flange kufuneka uphinde uqhutywe ngokweemfuno zokusetyenziswa kokuguqula kunye nokubhoboza kwimingxuma ejikeleze i-circumference ye-flange.
