Ngophuhliso oluqhubekayo loqoqosho kunye nenkqubela phambili eqhubekayo yoluntu, ibonelele ngobutyebi bempahla yabathengi, idala iimeko ezilungileyo zokuphucula imigangatho yokuphila yabantu kunye nokuphishekela ubomi bomntu, ngaloo ndlela ikhawulezisa imfuno yempahla yabathengi, kunye ne-TPU. iimveliso yenye yazo, ke yintoni ekufuneka ithathelwe ingqalelo kwinkqubo yokubumba inaliti ye-TPU? Okulandelayo, siya kukwazisa ngokweenkcukacha.
1. Isantya se-injection kunye nesikhundla sokuguqulwa koxinzelelo kufuneka sibekwe ngokuchanekileyo. Ukubeka indawo engachanekanga kuya kwandisa ubunzima bokuhlalutya kwesizathu, okungekho kulungelelaniso olukhawulezayo noluchanekileyo lwenkqubo.
2. Xa umthamo womswakama we-TPU udlula i-0.2%, awuyi kuchaphazela kuphela ukubonakala kwemveliso, kodwa kunye neempawu zomatshini ziya kuhlahloka ngokucacileyo, kwaye umkhiqizo owenziwe nge-injection uya kuba ne-elasticity embi kunye namandla aphantsi. Ngoko ke, kufuneka yomiswe kwiqondo lobushushu le-80 ° C ukuya kwi-110 ° C kwiiyure ezi-2 ukuya kwii-3 ngaphambi kokubunjwa kwenaliti.
3. Ukulawulwa kobushushu bokusebenza kunempembelelo ebalulekileyo kubungakanani bokugqibela, imilo kunye nokuguqulwa kwemveliso. Ubushushu bokusebenza buxhomekeke kwibakala le-TPU kunye neemeko ezithile zoyilo lokubumba. Umkhwa oqhelekileyo kukuba ukufumana i-shrinkage encinci, kuyimfuneko ukwandisa ubushushu bokusebenza.
4. Uxinzelelo olucothayo kunye nexesha elide lokubamba luya kukhokelela kwi-molecular orientation. Nangona kunokwenzeka ukufumana ubungakanani obuncinci bemveliso, ukuguqulwa kwemveliso kukhulu, kwaye umehluko phakathi kwe-transverse kunye ne-longitudinal shrinkage inkulu. Uxinzelelo olukhulu lokubamba luya kubangela ukuba i-colloid igxininiswe ngokugqithisileyo kwi-mold, kwaye ubungakanani bemveliso emva kokubunjwa bukhulu kunobukhulu bendawo yokubumba.
5. Ukukhethwa kwemodeli yomshini wokubumba inaliti kufuneka ifaneleke. Ubungakanani obuncinciisitofu ukubumba iimvelisokufuneka ikhethwe njengoomatshini bokubumba obuncinci benaliti ngokusemandleni, ukwenzela ukuba kwandiswe i-injection stroke, iququzelele ulawulo lwendawo, kunye nokuguqula ngokufanelekileyo isantya sokutofa kunye noxinzelelo.
6. Umbhobho womatshini wokubumba umjovo kufuneka ucocwe, kwaye ukuxubana kwezinto ezimbalwa kakhulu eziluhlaza kuya kunciphisa amandla omatshini emveliso. Imigqomo ecocwe nge-ABS, PMMA kunye ne-PE kufuneka ihlambuluke kwakhona ngezinto ze-TPU ze-nozzle ngaphambi kokuba i-injection isuse izinto eziseleyo kwi-barrel. Xa uhlambulula i-hopper, ingqalelo ekhethekileyo kufuneka ihlawulwe ekucoceni ixabiso elincinci lezinto eziluhlaza kunye nezinye iipropati kwindawo yokudibanisa phakathi kwe-hopper kunye nesiseko somatshini wokubumba umjovo. Le nxalenye kulula ukuhoywa ngabasebenzi abaninzi bezobugcisa kwimveliso.
