Izithako eziphambili kunye neempawu zeplastiki
Iiplastiki eziqhelekileyo zonke zenziwe ngezinto zendalo ezifana neselulosi, amalahle, igesi yendalo, ityuwa kunye neoli ekrwada ngokusebenzisa i-polymerization okanye inkqubo ye-polycondensation, kwaye zombini zifuna i-catalysts ethile.Kwi-reactor ye-polymerization, ii-monomers ezifana ne-ethylene kunye ne-propylene zidityaniswe kunye ukuze zenze imixokelelwane emide ye-polymer.I-polymer nganye ineepropati zayo, isakhiwo kunye nobukhulu ngokuxhomekeke kwiindidi ezahlukeneyo ze-monomers ezisisiseko ezisetyenzisiweyo.
Zininzi iintlobo ezahlukeneyo zeeplastiki, kodwa zinokudityaniswa zibe ziintsapho ezimbini eziphambili zepolymer:
I-1.Thermoplastics (ethambisayo xa ifudumeza kwaye iphinde iqine kwakhona xa ipholisa).
2.Thermosets (ezingakhe ithambe xa sele zibunjiwe).
Zeziphi iinkonzo esinokuzinika malunga neeplastiki
Izitofu zeplastiki zokubumba:
Ukubumba isitofu yenye yezona ndlela zisetyenziswa kakhulu kwimveliso yamalungu eplastiki kwaye lilitye lembombo lamandla okuvelisa kaRuiCheng.Isitofu sokubumba kukufakela imathiriyeli eshushu kwipatheni, ebizwa ngokuba ngundo, ethi ke iphole ibe yindawo ekumgangatho ophezulu, eyomeleleyo kwaye ephindaphindanayo.
Isitofu sokubumba siphindaphindwa kakhulu, nto leyo eyenza ukuba ibe yinto entle ukuhambelana kophawu kunye nokuthembeka kwenxalenye.Oku kwenza ukuba isitofu sisebenze ngokugqithisileyo kwaye singabizi kakhulu kwimveliso yomthamo ophezulu.
ukuba usikhethe njengababoneleli bakho beplastiki, sinokubonelela ngexabiso eliphantsi kunye nemveliso ephezulu kakhulu
Isitofu esikhawulezayo sokungunda:
Ukubumba inaliti ekhawulezileyo (i-RIM) yinkqubo yokubumba yesitofu eyilelwe ukwenziwa kweebhetshi ezincinci zamalungu eplastiki anamaxesha amafutshane okukhokela kunenkqubo yokubumba inaliti eqhelekileyo.Ngokubanzi, izixhobo ezisetyenziselwa i-RIM ziyafana nezo zisetyenziselwa ukubumba inaliti yemveliso yesiqhelo ngaphandle kokuba i-RIM yokubumba inaliti yenzelwe ukujika ngokukhawuleza endaweni yokuqina kwemveliso yochungechunge olude.
Ukugqithisa:
I-Overmolding yinkqubo yokubumba inaliti enamanyathelo amaninzi apho izinto ezimbini okanye ngaphezulu zibunjwa ngaphezulu kwenye.I-Overmolding ngamanye amaxesha ibizwa ngokuba kukubumba okuphindwe kabini kuba yinkqubo enamanyathelo amabini.
Okokuqala, icandelo elisisiseko (elinye igama elibizwa ngokuba yi-substrate) liyabunjwa kwaye livunyelwe ukunyanga.Ii-substrates ezigqithisiweyo zihlala zenziwe ngeplastiki.Emva koko, umaleko wesibini ubumba ngokuthe ngqo phezulu kweyokuqala ukudala iqhekeza elilodwa eliqinileyo.I-Overmolding idla ngokusetyenziswa ukwenza iindawo zeplastiki ezinesiphatho serabha.Inkqubo yokudubula kabini yokugqithisa ibrashi yamazinyo, umzekelo, ibandakanya ukwenza umaleko wesiseko somqheba weplastiki kunye nomgangatho ophezulu werabha (ukwenza ukuba ibhrashi yamazinyo ingatyibiliki ukuyibamba).
Ukungunda okunemibala emibini:
Ukubumba inaliti enemibala emibini yinkqubo yokuvelisa esetyenziswa xa kubhekiswa kubumba izinto ezimbini/imibala ibe yinxalenye enye yeplastiki, obubuchwephesha obudibanisa izinto ezimbini okanye imibala emibini eyahlukeneyo ibe yinxalenye yeplastiki ephelayo ngokusebenzisa umatshini wokubumba we-2k.
Ukusetyenziswa kwamalungu eplastiki
Iiplastiki eziphucukileyo zibalulekile kuyilo lweemoto.Phantse wonke umgangatho wemoto yanamhlanje-ukusuka kukhuseleko kunye nokusebenza ukuya ekusebenzeni kakuhle kunye nobuhle-uxhomekeke kwiiplastiki kwaye, ngokunyuka, i-polymer composites ukuhlangabezana nokulindela kwabathengi okuqhubekayo.
Njengomthengisi weplastiki yaseChina, sikwanikela ingqalelo ekusebenziseni iplastiki kwishishini leemoto kwaye sigxile kuyilo olungaphezulu kakhulu umgangatho ophezulu wezinto zeplastiki.Imveliso yethu ithengisa kuyo yonke indawo, ngakumbi iYurophu yaseSlovakia naseRomania.
Okwangoku iplastiki isetyenziswe ngokubanzi kwishishini lezemidlalo, izixhobo ezininzi zecandelo lezemidlalo zenziwe ngeplastiki.njengezixhobo zemidlalo Ivili,ivili lomatshini wokusebenzela intenetya.Kwezi zixhobo zemidlalo sihlala sisebenzisa ukugqithisa ukukhusela inxalenye ebalulekileyo.Amalungu eplastiki emidlalo yethu athandwa kakhulu eBrazil, ukuba ufuna ukwazi ngakumbi, nceda ujonge imeko yethu okanye iimveliso malunga neenxalenye zeplastiki zemidlalo.
Ubukhulu becala, iiplastiki zonyango ziyahluka kwiipropati kunye neempawu.Ngenxa yeemfuno ezingqongqo zolawulo lwamalungu onyango, iinjineli zethu zisebenzisa iipolima zeplastiki zonyango kwizicelo ezithile zempilo, ukusuka kwizixhobo zotyando ukuya kwizinto zonyango.Ukuqinisekisa ukuba ezi nxalenye zeplastiki zonyango ziyahlangabezana nemigangatho yezonyango, senze amawaka eemvavanyo.Ngoku ezi plastiki zonyango zisetyenziselwa iiprototypes zonyango kunye neenxalenye zinokuzisa ukuxhathisa okufanelekileyo kwimpembelelo, ukunxiba, ubushushu kunye nokubola.Kwangaxeshanye, la macandelo eplastiki anokugcina ukusebenza okuphezulu emva kokuthobela inzala okanye umzimba.
Iinzuzo zamalungu eplastiki
➢ Uyilo oluguquguqukayo olugqwesileyo
➢ Uluhlu olubanzi lwemathiriyeli
➢ Imbonakalo entle kakhulu.
➢ Amaxesha okwenziwa akhawulezayo
➢ Ukuphinda-phinda okukhulu kunye nokunyamezelana
Yeyiphi iplastiki esidla ngokuyisebenzisa ekutofweni
Ukuze ufunde ngakumbi malunga nobugcisa benaliti yeplastiki, unakoqhagamshelana wethuiqela lokuthengisa ukuxoxa ngesicelo sakho esisodwa.
