Umatshini wokubumba inaliti ye-EVA/FRB: uguquko kwimveliso
Ukubunjwa kwe-injection kuye kwaba yinkqubo ephambili kwishishini lokuvelisa, okwenza ukuba ukuveliswa kweemveliso zeplastiki kukhulu ngokuchaneka okuphezulu kunye nokusebenza kakuhle.Kwiminyaka yakutshanje, ukuphuhliswa koomatshini bokubumba inaliti ye-EVA/FRB iye yaguqula indlela abavelisi abavelisa ngayo iindidi ngeendidi zeemveliso, ibonelela ngokusebenza okuphuculweyo kunye nokuguquguquka.Eli nqaku liphonononga ezona mpawu ziphambili kunye nezibonelelo zoomatshini bokubumba inaliti ye-EVA/FRB kunye nefuthe labo kwimveliso.
I-EVA (i-ethylene vinyl acetate) kunye ne-FRB (umxube werabha we-foam) zizinto ezimbini eziqhelekileyo ezisetyenziswa ekuveliseni izihlangu, iinxalenye zeemoto kunye neentlobo zeemveliso zabathengi.Imfuno ekumgangatho ophezulu kunye neemveliso ezihlala ixesha elide ezenziwe kwezi zixhobo ziqhuba imfuno yobuchwepheshe bokubumba inaliti.Oomatshini bokubumba inaliti ye-EVA/FRB yenzelwe ukuhlangabezana nale mfuno ngokubonelela ngolawulo oluchanekileyo lwenkqubo yokubumba ukuvelisa iimveliso ezinomgangatho ongaguqukiyo kunye nokusebenza.
Enye yeempawu eziphambili ze-EVA / FRB zoomatshini bokubumba inaliti kukukwazi ukucubungula uluhlu olubanzi lwezinto eziphathekayo, kuquka i-EVA, i-FRB kunye nezinye izinto ze-thermoplastic.Oku kuguquguquka kuvumela abavelisi ukuba bavelise iimveliso ezahlukeneyo ngaphandle kokusebenzisa oomatshini abaninzi, ukulungelelanisa iinkqubo zokuvelisa kunye nokunciphisa iindleko.Ukongeza, oomatshini bokubumba be-EVA / FRB abaphambili baxhotyiswe ngobushushu kunye neenkqubo zokulawula uxinzelelo ukuze kuqinisekiswe iimeko ezifanelekileyo zokubumba izinto ezahlukeneyo, ngaloo ndlela zivelisa iimveliso ezigqityiweyo ezikumgangatho ophezulu.
Ukongeza, oomatshini bokubumba inaliti ye-EVA/FRB baziwa ngokusebenza kwabo okuphezulu kunye nemveliso.Aba matshini baxhotyiswe nge-hydraulic ephezulu kunye neenkqubo zombane ezinciphisa amaxesha okujikeleza kunye nokunciphisa ixesha lokunciphisa ukunyusa imveliso.Ulawulo oluchanekileyo lwenaliti kunye neenkqubo zokubamba luvumela uyilo oluntsonkothileyo ukuba luveliswe ngenkunkuma encinci, ukwenza ngcono ukusetyenziswa kwezinto kunye nokunciphisa iindleko zokuvelisa ngokubanzi.
Ukongeza, oomatshini bokubumba inaliti ye-EVA/FRB bayilwe ngolawulo olusebenziseka lula kunye nojongano, bebenza ukuba bafikeleleke kubaqhubi abanamanqanaba amava ahlukeneyo.Oku kufikeleleka, kudityaniswe nezakhono ezizenzekelayo zomatshini, kuvumela ukuhlanganiswa okungenamthungo kwiindawo zokuvelisa, ukwandisa amandla okuvelisa ngokubanzi kunye nobuchule.
Impembelelo yomatshini wokubumba inaliti ye-EVA/FRB kwishishini lemveliso inkulu.Ngokubonelela ngokusebenza okongeziweyo kunye nokuguquguquka, aba matshini benza ukuba abavelisi bahlangabezane nemfuno ekhulayo yeemveliso ezikumgangatho ophezulu ezenziwe kwi-EVA, FRB kunye nezinye izixhobo ze-thermoplastic.Ukukwazi ukuvelisa uluhlu olwahlukeneyo lweemveliso ezinomgangatho ongaguqukiyo kunye nokusebenza kakuhle kwenza abavelisi bahlale bekhuphisana kwindawo yentengiso kwaye bahlangabezane neemfuno ezihlala zitshintsha zabathengi.
Isishwankathelo, oomatshini bokubumba inaliti ye-EVA/FRB bayiguqule imveliso ngokubonelela ngeempawu eziphambili kunye nokuguquguquka ukuvelisa iimveliso ezikumgangatho ophezulu.Amandla oomatshini okuphatha izinto ezahlukeneyo, ukusebenza kakuhle okuphezulu kunye noyilo olusebenziseka lula kuye kwaba zizixhobo eziyimfuneko kubavelisi abafuna ukuhlala phambi kwegophe kwimarike eguqukayo ngokukhawuleza.Njengoko imfuno yeemveliso ezenziwe kwi-EVA, i-FRB kunye nezinye izinto ze-thermoplastic ziqhubeka zikhula, indima yomatshini wokubumba inaliti ye-EVA/FRB ekubumbeni ikamva lokuvelisa ayinakuphikiswa.
