Inkcazo yendlela yokubumba inaliti yeplastiki kunye nenkqubo yokuvelisa inyathelo ngenyathelo

Kwiminyaka engamashumi amahlanu edlulileyo ishishini lemathiriyeli yeplastiki liye laphuhliswa, ngokomlinganiselo omkhulu, lilawula phezu kwemathiriyeli esisiseko, lide lagqitha ishishini lentsimbi. Iiplastiki zingene kuwo onke amakhaya kungakhathaliseki isimo sentlalo, kuzo zonke izixeko ezibandakanya iindawo ezikude kakhulu kunye nakumazwe athuthukileyo, njengakuwo wonke uqoqosho. Uphuhliso lweli shishini lunomdla kwaye lutshintshe indlela yehlabathi esiphila kulo.

Inkqubo yokubumba isitofu

Iikhompawundi zePlastiki zahluke kakhulu omnye komnye kwaye ziboleka kwiindlela ezahlukeneyo zokusetyenzwa. Isixhobo ngasinye silungele enye yeendlela, nangona ezininzi zinokuveliswa ngabaninzi babo. Kwiinkqubo ezininzi, izinto zokubumba zingumgubo okanye ifom yegranular, nangona kwabanye kukho umsebenzi owenziwe kwangaphambili ngaphambi kokusetyenziswa. Xa ubushushu busetyenziswa kwi-thermoplastic material ukuze bunyibilike, kuthiwa iplastiki. Sele enyibilikisiwe okanye ubushushu imathiriyeli elaminethiweyo kungenziwa ukuba ahambe ngokufaka uxinzelelo kunye nokuzalisa isikhunta apho izinto ziqina kwaye zithatha imilo yokubumba. Le nkqubo yaziwa ngokuba ukudumba kwenaliti. Umgaqo osisiseko wokubumba inaliti uquka le misebenzi mithathu isisiseko:

1. a) Phakamisa ubushushu beplastiki ukuya kwindawo apho inokuhamba khona phantsi koxinzelelo. Oku ngokuqhelekileyo kwenziwa ngokufudumeza kunye nokuhlafuna i-granules eqinile yezinto ukwenza ukunyibilika kunye ne-viscosity efanayo kunye nobushushu. Okwangoku, oku kwenziwa ngaphakathi kombhobho womatshini ngokusebenzisa i-screw, ebonelela ngomsebenzi womatshini (ukungqubuzana) odibeneyo kunye nobushushu bombhobho onyibilikayo (iplastiki) iplastiki. Oko kukuthi, i-screw ithutha, ixube kwaye ifake iplastiki izinto zeplastiki. Oku kuboniswa kumfanekiso
2. b) Vumela ukuqiniswa kwezinto kwi-mold evaliweyo. Kweli nqanaba izinto ezinyibilikisiweyo sele elaminethiweyo kumgqomo womatshini zigqithiselwa (zitofelwe) ngokusebenzisa umlomo wombhobho, odibanisa umphanda kwimijelo eyahlukeneyo yokungunda de ifikelele kwimingxuma apho ithatha imilo yemveliso yokugqibela.
3. c) Ukuvulwa komngundo wokukhutshwa kweqhekeza. Oku kwenziwa emva kokugcina izinto phantsi koxinzelelo ngaphakathi kwesikhunta kwaye emva kokuba ukushisa (okwakusetyenziswe kwiplastiki) kususwe ukuvumela ukuba izinto ziqiniswe ngendlela efunwayo.

Kwiinkqubo ezahlukeneyo zokubumba, ukuhlukahluka kwiqondo lokushisa elinyibilikayo okanye iplastiki lidlala indima eyahlukileyo kuxhomekeke ekubeni ingaba yimpahla ye-thermoplastic okanye i-thermofix.

Ukudityaniswa kwe Thermoplastic izinto zenziwa ngokuthe ngcembe kwi-cylinder yeplastiki, phantsi kweemeko ezilawulwayo. Ukufudumeza kwangaphandle okunikezelwa yi-cylinder ye-plasticizing yongeza ukushisa okwenziwa yi-friction ye-spindle ejikelezayo kunye nokuxuba izinto eziphathekayo. Ukulawulwa kweqondo lokushisa kwiindawo ezahlukeneyo ze-cylinder ye-plasticizing kwenziwa ngokusebenzisa i-thermocouples efakwe kwiindawo ezahlukeneyo endleleni yezinto eziphathekayo, ukusuka kwi-hopper ukuya kwi-nozzle. I-Thermocouples ixhunyiwe kwizixhobo zokulawula ngokuzenzekelayo, ezigcina ukushisa kwendawo nganye kwinqanaba elimiselweyo. Nangona kunjalo, iqondo lobushushu lokwenyani lokunyibilika eliza kugalelwa kubumba linokwahluka kwelo libhalwe zii-thermocouples nokuba kwi-cylinder okanye kwi-nozzle.

Ngenxa yesi sizathu, kuyacetyiswa ukuba ulinganise ngokuthe ngqo ukushisa kwezinto ngokwenza into encinci iphume kwi-nozzle kwi-plate ye-insulating kwaye wenze umlinganiselo apho. Ukwahluka kwiqondo lokushisa kwi-mold kunokuvelisa iinxalenye ezinomgangatho oguquguqukayo kunye nemilinganiselo eyahlukeneyo, ukuhlukana ngalunye kobushushu bokusebenza kubangela ukupholisa ngokukhawuleza okanye okucothayo kobunzima obutyhidiweyo obufakwe kwi-mold cavity. Ukuba iqondo lokushisa lokubunjwa liyancipha, inxalenye ebunjiweyo ipholisa ngokukhawuleza kwaye oku kunokudala ukuqhelaniswa okuphawulweyo kwisakhiwo, uxinzelelo oluphezulu lwangaphakathi, iimpawu zomatshini kunye nokubonakala okungahambi kakuhle kwendawo.
