1. Ukubumba ngesandla

Ukubumba ngesandla yindlela eqhelekileyo yokwenza iiflange zeplastiki eziqinisiweyo zefiberglass (FRP). Le ndlela ibandakanya ukubeka ngesandla i-resin-impregnatedilaphu le-fiberglassokanye iimathi zibe yimold kwaye zivumele ukuba ziphile. Inkqubo ethile yile ilandelayo: Okokuqala, kwenziwa umaleko we-liner wangaphakathi otyebileyo we-resin kusetyenziswa ilaphu le-resin kunye ne-fiberglass. Emva kokuba umaleko we-liner uphilile, uyasuswa kwimold, kwaye umaleko wesakhiwo uyakhiwa. Emva koko i-resin ixutywa kumphezulu wemold kunye ne-liner yangaphakathi. Iileya zelaphu le-fiberglass ezisikiweyo kwangaphambili zibekwa ngokwesicwangciso sokubeka esimiselweyo, kwaye umaleko ngamnye uxinene kusetyenziswa i-roller ukuqinisekisa ukumiliswa ngokupheleleyo. Nje ukuba ubukhulu obufunekayo bufezekiswe, indibano iyanyangeka kwaye isuswe.

I-matrix resin yokubumba ngesandla isebenzisa i-epoxy okanye i-polyester engagcwaliyo, ngelixa izinto zokuqinisa ziyi-medium-alkali okanyeilaphu le-fiberglass elingena-alkali.

Iingenelo: Iimfuno eziphantsi zezixhobo, ukukwazi ukuvelisa iiflanges ezingezizo ezisemgangathweni, kwaye akukho miqathango kwijiyometri yeflange.

Iingxaki: Amaqamza omoya ayenzeka ngexesha lokucocwa kwe-resin anokubangela ukuba kubekho imingxunya, anciphise amandla oomatshini; ukusebenza kakuhle kwemveliso; kunye nokugqitywa komphezulu okungalinganiyo nongacocwanga.

2. Ukubumba ngoxinzelelo

Ukubumba ngokucinezela kubandakanya ukubeka ubungakanani obulinganisiweyo bezinto zokubumba kwi-flange mold kwaye uyinyange phantsi koxinzelelo usebenzisa i-press. Izinto zokubumba ziyahluka kwaye zinokubandakanya ii-fiber compounds ezixutywe kwangaphambili okanye ezifakwe ngaphambili, iziqwenga zelaphu le-fiberglass ezisetyenzisiweyo, ii-recycled fiberglass cloth rings/strips, ii-stacked SMC (sheet molding compound), okanye ii-preforms zelaphu le-fiberglass ezilukiweyo kwangaphambili. Ngale ndlela, i-flange disk kunye nentamo zibunjwa ngaxeshanye, ziphucula amandla adibeneyo kunye nokuqina kwesakhiwo ngokubanzi.

Iingenelo: Ukuchaneka okuphezulu, ukuphindaphindwa, ukufaneleka kwemveliso yobuninzi ezenzekelayo, ukukwazi ukwenza iiflanges ezintsonkothileyo zentamo ethambileyo kwinqanaba elinye, kunye neendawo ezigudileyo ezintle ezingafuneki emva kokulungiswa.

Iingxaki: Iindleko eziphezulu zokubumba kunye nemida yobukhulu beflegi ngenxa yemida yebhedi yokucinezela.

3. Ukubumba iResin Transfer (RTM)  

I-RTM ibandakanya ukubeka i-fiberglass reinforcement kwi-mold evaliweyo, ukufaka i-resin ukuze ifake iifayibha, kunye nokucola. Le nkqubo ibandakanya:

• Ukubeka i-preform ye-fiberglass ehambelana ne-geometry ye-flange kwindawo yokubumba.
• Ukufaka i-resin ene-viscosity ephantsi phantsi kobushushu obulawulwayo kunye noxinzelelo ukuze kugcwaliswe i-preform kwaye kususwe umoya.
• Ukufudumeza ukuze kulungiswe kwaye kususwe iflengi egqityiweyo.

Iiresini zihlala ziyi-polyester engagcwaliyo okanye i-epoxy, ngelixa ezinye izinto eziqinisayo ziqukaiimathi eziqhubekayo zefiberglassokanye amalaphu alukiweyo. Izinto zokugcwalisa ezifana ne-calcium carbonate, i-mica, okanye i-aluminium hydroxide zingongezwa ukuphucula iimpawu okanye ukunciphisa iindleko.

Iingenelo: Imiphezulu egudileyo, imveliso ephezulu, ukusebenza kwesikhunta esivaliweyo (ukunciphisa ukukhutshwa komoya kunye neengozi zempilo), ukulungelelaniswa kwefayibha kwicala ukuze kubekho amandla angcono, utyalo-mali oluphantsi, kunye nokusetyenziswa okuncitshisiweyo kwezinto/amandla.

4. Ukubumba iResin encediswa yiVacuum (i-VARTM)

I-VARTM iguqula i-RTM ngokufaka i-resin phantsi kwe-vacuum. Le nkqubo ibandakanya ukuvala i-preform ye-fiberglass kwi-mold yesilisa ngebhegi ye-vacuum, ukukhupha umoya kwi-mold cavity, kunye nokutsala i-resin kwi-preform ngoxinzelelo lwe-vacuum.

Xa kuthelekiswa ne-RTM, i-VARTM ivelisa iiflanges ezine-porosity ephantsi, umxholo ophezulu wefayibha, kunye namandla aphezulu oomatshini.

5. Ukubumba i-resin encediswa yi-airbag

Ukubumba i-RTM encediswa yi-Airbag kukwaluhlobo lobuchwepheshe bokubumba obuphuhliswe ngokusekelwe kwi-RTM. Inkqubo yokulungiselela iiflanges ngale ndlela yokubumba imi ngolu hlobo lulandelayo: i-preform yeglasi enemilo yeflange ibekwa phezu komphezulu we-airbag, ezaliswa ngumoya ize yande ngaphandle kwaye ivalelwe kwindawo ye-cathode mold, kwaye i-preform yeflange phakathi kwe-cathode mold kunye ne-airbag iyaxinwa kwaye inyangwe.

Iingenelo: ukwandiswa kwe-airbag kunokwenza i-resin ihambe iye kwinxalenye ye-preform engafakwanga, ukuqinisekisa ukuba i-preform ifakwa kakuhle yi-resin; umxholo we-resin unokulungiswa ngoxinzelelo lwe-airbag; uxinzelelo olukhutshwa yi-airbag lufakwa kumphezulu wangaphakathi we-flange, kwaye i-flange emva kokulungiswa ine-porosity ephantsi kunye neempawu ezilungileyo zoomatshini. Ngokubanzi, emva kokulungiselelaI-FRPiflange ngendlela yokubumba engentla, umphezulu wangaphandle weflange nawo kufuneka ucutshungulwe ngokweemfuno zokusetyenziswa kokujika nokubhoboza imingxunya ejikeleze umjikelo weflange.
