Zeziphi iintlobo zokubumba zeplastiki?

Ngethuba lokusetyenziswa kwe-molds yeplastiki, kuya kuba neefom ezahlukeneyo zokungaphumeleli, eziza kuchaphazela ukusebenza kunye nobomi bobumba.Uhlobo lokusilela ikakhulu lubandakanya iintlobo ezi-6: ukulahleka kokusila, ukungaphumeleli kokukhathala, ukungaphumeleli kokubola, ukungaphumeleli kokukhathala kobushushu, ukungaphumeleli kokubambelela, ukungaphumeleli kokuguqulwa.

Oku kulandelayo kwazisa ezi ndlela zi-6 zilandelayo zomngundo weplastiki:

(1) Ukulahlekelwa yimpembelelo: ukunxiba yenye yeendlela eziqhelekileyo zokungaphumeleli kokungunda.Kwinkqubo yoqhagamshelwano kunye nezixhobo zeplastiki, kuya kubangela ukugqoka phezu kwendawo yokubumba.Ukugqoka kwexesha elide kuya kwandisa ubungakanani besikhunta kunye nobukhulu bomhlaba, okuya kuchaphazela umgangatho kunye nokuchaneka kwemveliso.

(2) Ukungaphumeleli kokukhathala: Ukungaphumeleli kokukhathala ngenxa yokwandiswa kwe-crack kunye nekhefu eyenzekayo phantsi kokulayishwa kwexesha elide lokubumba.Ngethuba lokusetyenziswa kweembumba zeplastiki, ukulayishwa koxinzelelo ngokuphindaphindiweyo kunamava.Ukuba idlula umda wokudinwa kwezinto eziphathekayo, ukukhathala kuya kuphumelela.Ukungaphumeleli kokukhathala ngokuqhelekileyo kubonakaliswa njengokuqhekeka, ukuphuka okanye ukuguqulwa.

(3) Ukungaphumeleli kokubola: I-Corrosion ibhekisela kukusilela okubangelwa ukukhukuliseka komphezulu we-mold yi-chemical substances.Ukubumba kweplastiki kunokuqhagamshelana neekhemikhali ezithile, ezifana ne-asidi, i-alkali, njl., ebangela ukubola komphezulu wobumba.Umhlwa uya kwenza umphezulu wokungunda ube rhabaxa kwaye uvelise imingxuma, echaphazela ubomi benkonzo kunye nomgangatho wemveliso yobumba.

(4) Ukungaphumeleli komkhuhlane: ukudinwa kobushushu kubangelwa kukungaphumeleli kwesikhunta phantsi kobushushu obuphezulu bexesha elide.Iimbumba zeplastiki kufuneka zithwale umjikelo wokupholisa ubushushu obuphezulu ngexesha lokutofa, okuya kubangela ukwanda kwe-thermal kunye nokucutheka kwezinto zokubumba, okuya kubangela ukusilela kokukhathala kobushushu.Ukukhathala kobushushu ngokuqhelekileyo kubonakaliswa njengokuqhekeka, ukuguqulwa okanye ukuphuka.

(5) Ukungaphumeleli kwe-adhesion: ukunamathela kubhekisela kwizinto zeplastiki ezifakwe kumphezulu we-mold ngexesha lenkqubo yokubumba.Njengoko inani le-injection ye-injection landa, ukunamathela kwendawo yokubumba kuya kusilela.Ukubambelela kuya kwenza umphezulu we-mold rough, echaphazela ukubonakala kunye nobukhulu obuchanekileyo bemveliso.

(6) Ukungaphumeleli kokuguqulwa: Iiplastiki zeplastiki ziya kubandezeleka ngenxa yoxinzelelo olukhulu lokubumba kunye nokutshintsha kweqondo lokushisa ngexesha lokutofa, okunokubangela ukuguqulwa kwesikhunta.I-deformation ye-mold iya kubangela ukuba ubungakanani bemveliso bube bungalunganga, ukubonakala kakubi, okanye nokuba kungafumaneki.

Ezi zingentla zezinye iindlela eziqhelekileyo zeiimbumba zeplastiki.Uhlobo ngalunye lokungaphumeleli luya kuba nenqanaba elahlukileyo lempembelelo ekusebenzeni kunye nobomi bombumba.Ukuze kwandiswe ubomi benkonzo yokubunjwa kweplastiki, amanyathelo afanelekileyo okugcinwa kufuneka athathwe, kwaye izinto ezinjengokukhethwa kwezinto eziphathekayo, inkqubo yokucubungula kunye nohlalutyo loxinzelelo zithathelwa ingqalelo kwindlela yokuyila kunye nokuvelisa.
