Isiseko senayiloni yeenkwenkwezi ezintlanuisitulo seofisiyenziwe ngenayiloni kunye ne-fiberglass yokubumba inaliti, imveliso yeplastiki eveliswa ngokubumba inaliti, kwaye ifakwe kwi-cylinder yegesi.
Emva kokuqiniswa kunye nokuguqulwa ngefiber yeglasi (GF), amandla, ubulukhuni, ukuxhathisa ukukhathala, ukuzinza komda kunye nokumelana nokunyuka kwe-nylon PA kuphuculwe kakhulu.Yenza isiseko sesitulo sixhathise kwaye siqine.
Nangona kunjalo, kweyona nkqubo yemveliso, ukusasazeka kunye namandla okubopha ifayibha yeglasi kwi-PA resin matrix kunempembelelo enkulu ekusebenzeni kwemveliso.Ifayibha yeglasi eyomeleziweyo yeemveliso zokubumba inaliti ye-PA zihlala zineziphene ezahlukeneyo.
Sinamashumi eminyaka yamava ekubumbeni inaliti kwaye njengabavelisi singathanda ukwabelana ngeengcinga zethu:
Siza kulwahlula esi sihloko sibe ngamacandelo amabini, kubandakanywa inkqubo yokubumba inaliti ye-fiberglass eyomeleziweyo ye-PA kunye nezizathu kunye nezisombululo zeziphene.Kweli nqaku, siza kwazisa inkqubo yokubumba inaliti.
Ifayibha yeglasi yomelezwe inkqubo yokubumba inaliti yenayiloni
Emva kokumisela imathiriyeli ekrwada yeplastiki, umatshini wokubumba inaliti kunye nokungunda, ukhetho kunye nolawulo lweeparamitha zenkqubo yokubumba isitofu sisitshixo sokuqinisekisa umgangatho wamacandelo.Inkqubo epheleleyo yokubumba isitofu kufuneka ibandakanye ukulungiswa ngaphambi kokubumba, inkqubo yokubumba i-injection, iinxalenye emva kokucubungula, njl.
1. Ukulungiswa ngaphambi kokubumba
Ukwenza inkqubo yokutofa ihambe kakuhle kwaye iqinisekise umgangatho wesiseko sesitulo seofisi yenayiloni yeplastiki, amanye amalungiselelo ayimfuneko kufuneka enziwe ngaphambi kokubumba.
(1) Qinisekisa ukusebenza kwemathiriyeli ekrwada
Ukusebenza kunye nomgangatho wezinto eziluhlaza zeplastiki ziya kuchaphazela ngokuthe ngqo umgangatho wesiseko sesihlalo se-nylon yeplastiki.
(2) Ukufudumeza kwangaphambili kunye nokomiswa kwemathiriyeli ekrwada
Ngethuba lenkqubo yokubumba iplastiki, amanzi asele kwi-raw material aya kunyuka abe ngumphunga wamanzi, oya kuhlala ngaphakathi okanye phezu kwesiseko.
Oku kunokwenza imigca yesilivere, amanqaku, amaqamza, imingxuma, kunye nezinye iziphene.
Ukongeza, ukufuma kunye nezinye iikhompawundi ezinobunzima obuphantsi bemolekyuli nazo ziya kudlala indima ebambekayo kubushushu obuphezulu kunye nemeko yoxinzelelo oluphezulu.Oku kunokubangela ukuba i-PA idityaniswe ngokunqamlezayo okanye ithotywe, ichaphazele umgangatho womphezulu kunye nokusebenza okuthoba kakhulu.
Iindlela zokomisa eziqhelekileyo ziquka ukomisa umjikelo womoya oshushu, ukomisa i-vacuum, ukomisa i-infrared njalo njalo.
2. Inkqubo yokutofa
Inkqubo yokutofa idla ngokuba nala manyathelo alandelayo: ukutyisa, ukufaka iplastiki, inaliti, ukupholisa kunye nokukhupha iplastiki.
(1) Ukondla
Ekubeni ukubunjwa kwenaliti kuyinkqubo yebhetshi, umyinge (umthamo othe rhoqo) uyafuneka ukuqinisekisa ukusebenza okuzinzileyo kunye nokufaka iplastiki.
(2) Ukwenza iplastiki
Inkqubo apho iplastiki eyongeziweyo ishushu kwi-barrel, iguqule iinqununu eziqinileyo zibe yimeko ye-viscous fluid kunye neplastiki enhle, ibizwa ngokuba yiplastiki.
(3) Isitofu
Kungakhathaliseki ukuba luhlobo luni lomatshini wokubumba osetyenzisiweyo, inkqubo yokubumba i-injection inokwahlulwa ibe ngamanqanaba amaninzi, njengokuzaliswa kwesikhunta, ukubamba uxinzelelo, kunye ne-reflux.
(4) Ucango luyapholiswa emva kokuba ngumkhenkce
Xa ukunyibilika kwenkqubo yesango iqhwa, akusekho mfuneko yokugcina uxinzelelo.Ngenxa yoko, i-plunger okanye isikrufu sinokubuyiswa kwaye uxinzelelo lweplastiki kwibhakethi lunokukhululwa.Ukongeza, izinto ezintsha zingongezwa ngelixa uzisa imidiya yokupholisa njengamanzi okupholisa, ioli okanye umoya.
(5) Ukubunjwa
Xa inxalenye ipholile kwiqondo lokushisa elithile, i-mold inokuvulwa, kwaye inxalenye ikhutshwe ngaphandle kwe-mold phantsi kwesenzo se-ejection mechanism.
3. Emva kokulungiswa kwamalungu
Unyango lwasemva lubhekisa kwinkqubo yokuzinzisa ngakumbi okanye ukuphucula ukusebenza kweendawo ezibunjiweyo zesitofu.Oku ngokuqhelekileyo kubandakanya unyango lokushisa, ukulawulwa komswakama, emva kokunyanga, njl.
Esinye isiseko sesitulo
Ukongeza kwi-nylon, kukho ezinye izinto, isinyithi se-aluminium kunye ne-chrome yensimbi, enenzuzo kunye nokungona kwayo.
Ngaphandle kwamathandabuzo, isiseko sesitulo seNylon sesona sisetyenziswa kakhulu kwimarike.
