I-Grastics yeBanga le-GAGICS-iPPSU

IPlastics yebanga lokutya - i-PPSU iqhuba ezo zinto

I-PPSU iqhuba amanyathelo okuhlwaya

1.Row ukulungiselela izinto

Lungiselela inani elifanelekileyo leegranuules ezomileyo kwaye zihlolwe.

2.Mlelo

Beka amasuntswana e-PPSU kwiqondo lokunyibilika, ukufudumeza ngaphezulu kwenqaku lokunyibilika, ukuze linyibilike ngokupheleleyo kwi-vislates yendlela yokuhamba.

3.Innection

I-PPSU enyibilikisiweyo ifakwe kwi-cavity ye-mold ukwenza ubume obufunayo.

I-4.kww yokubumba

Umoya oxinzelelweyo uyathunyelwa kwi-preform ukuba iyokwandisa ngaphakathi komnyama kwaye unamathele eludongeni lwe-modold cavity, kwaye ibeke ubume obufunwayo emva kokupholisa.

5.Ukuhlala

Isikhongozeli sisuswa ekubunjweni ukuze sigqitywe kwaye sisebenze.

6.Fnisating

Inkangeleko yesikhongozeli iposwele, inqunyulwe okanye iprintwe ukuphucula i-aesthetics kunye nokusebenza.

7. 7.Nikale kwaye ukupakisha

Ukuqhuba ihlolisiso esemgangathweni kwizikhongozeli ukuqinisekisa ukuba bakhululekile kwiziphene kwaye emva koko bapakisha ukuthengisa okanye ukusebenzisa.

Ukuqhubekeka kwe-PPSU kunye neemeko zokubumba

Iqondo lobushushu le-1.mold

Indawo yokunyibilika ye-PPSU imalunga ne-260 ° C, ke isitshixo senkqubo yokubumba kukulawula ubushushu obushushu. Iqondo lobushushu elililo lihlala liphakathi kwe-180 ° C ukuya kwi-230 ° C. Iqondo lobushushu linokuphakama kakhulu okanye liphantsi kakhulu, elinokubangela ukuba izinto zibole. Iqondo eliphezulu kakhulu okanye eliphantsi kakhulu linokukhokelela ekulweni okanye ukulahlekisa.

2.Umkhethe kunye nesantya

Ngenxa yolwelo oluhlwempuzekileyo lwe-PPSU, isidingo soxinzelelo oluphezulu lwenaliti (ngesiqhelo i-150-400mpa) kunye nenaliti ehamba kancinci (i-10 ukuya kwele-10) ngomzuzwana) ukuqinisekisa ukuba i-molten thermation igcwalise ngokupheleleyo ikona.

I-3.mold uyilo

Ngenxa yobume bemolekyuli esondeleyo ye-PPSU kunye ne-crystallinity ephezulu, uyilo kufuneka lunikele ingqalelo ukunqanda ukunyibilika kwinkqubo yokupholisa kunye nokulahlekisa. Kucetyiswa ukuba usebenzise imbaleki emfutshane, ubukhulu be-Wall yoyilo loyilo lokuqinisekisa ukugcwaliswa okulinganayo kunye nokupholisa ngokukhawuleza kokunyibilika.

4.Ukuqhubekeka

Emva kokuba iplastiki yePPSU ye-PPSU ifuna ukuba impanya, njengokuyoma nokunyanga, ukususa umswakama kunye nezixhobo zibe nzima kwaye zizinzile.

5.Khethe amanyathelo okhuseleko

Ngexesha lenkqubo yokuxhuzula inaliti, isantya sentsholongwane kunye nengcinezelo, kunye neqondo lobushushu lokudala kunye neemeko zokupholisa, kufuneka zilawulwe ngokungqongqo ukuthintela ukwenzeka kweebhubhu, i-shrintage kunye nezinye iingxaki. Ukongeza, ukunqongophala okuhlwempuzekileyo kwezinto ze-PPU kufuna ukusetyenziswa kwe-viscofity ephezulu kunye nee-nozzles.

Iimpawu ze-thermoming ye-PPSU ye-PPSU

I-1.Excellent yentsebenzo

I-PPSU inamamela obushushu obuphakathi, ukunganyangeki kweekhemikhali kunye neepropathi ezigqwesileyo, kwaye kunokuhlangabezana neemfuno ezahlukeneyo zeemilo ezintsonkothileyo kunye nemfuno ephezulu yeemveliso.

I-2.strong fihla ukuba

Ngokuhlengahlengiswa kobushushu obufudumeleyo, uxinezeleko lokubumba kunye noyilo olungeneyo kunye nezinye iiparamitha, unokwenza iimveliso zobungakanani obahlukeneyo, iimilo kunye nobunzima. Kwangelo xesha, ngonokongezwa kwinkqubo ebumbayo, njengokuqinisa imivalo, imisonto kunye nezinye izinto zokuphucula iipropathi zoomatshini kunye nokusebenza kweemveliso.

3. Iindleko zokulungisa iindleko

Xa kuthelekiswa nenaliti yokubumba kunye nezinye iinkqubo zokubumba, izixhobo zokungena ze-thorming kunye neendleko zeflethi ziphantsi, kwaye inkqubo yemveliso isebenzisa amandla angaphantsi, enceda ukunciphisa iindleko zemveliso.

4.UnVeroll

I-PPSU yinto enobuhlobo obuyingqongileyo enokuphinda isebenze. Kwangelo xesha, inkqubo ye-versing ye-therformation ivelisa inkunkuma encinci, elungele ukunciphisa ungcoliseko lwendalo.

5. Uluhlu lweZicelo

I-PPU Bluster Iimveliso ze-thormy zinokusetyenziswa kwezonyango, ukutya, ii-cosmetics, iimveliso ze-elektroniki kunye nezinye iinkalo ezininzi, imfuno yentengiso iphezulu.

Iimveliso ze-PPU zilungisa iingxaki eziqhelekileyo kunye nezisombululo zazo

1.Ukuthola kweebhubhu zomoya

Iibhubhu yingxaki eqhelekileyo yeemveliso ze-PPSU ikakhulu zibangelwa yiqondo lobushushu lokudakumba liphezulu kakhulu okanye isantya sesantya sikhawuleza kakhulu. Isisombululo kukunciphisa ubushushu obubumba, sicothe isantya sentsholongwane, kwaye kwangaxeshanye siyonyusa ixesha elinenaliti kunye nenqanaba lesibini lexesha lokufumana irhasi, ukuze livumele irhasi eyaneleyo yokuphelisa isisu.

2.Sshinkige

Iimveliso ze-PPSU kwinkqubo yokupholisa ziya kuvela i-shrinkige, ukuba ininzi i-shrinkige iya kukhokelela kwifuthe lemveliso. Isisombululo kukwandisa ubushushu obubunjiweyo kwinkqubo, kwaye kancinci kancinci inqanaba lokupholisa, kwaye kwangaxeshanye linokufaneleka ukwandisa ixesha lokwahlula inaliti kunye noxinzelelo lwenaliti, ukuze kuvumeleke umbandela wokungayisebenzisi.

3.cracks crocks

Ikakhulu ngenxa yoyilo olungenangqondo okanye ubushushu obubumba busezantsi kakhulu. Isisombululo kukujonga ukuba uyilo lokubulqwa lisengqiqweni, ukuba kukho nayiphi na ingxaki yokuhlengahlengiswa kwexesha. Kwangelo xesha linye ukuba kufanelekile ukuphucula ubushushu obubunjiweyo kunye neqondo lokushisa, licothe isantya sentsholongwane, ukuze kuvumeleke ukuba kuhlulwe izinto eziphathwayo kwaye ugcwalise ubumbano.

4. Ukubonakala kwengqolowa yesilivere yesilivere

Kubangelwa kukufuma okanye i-volaties egqithisileyo kwizixhobo ze-PPU, isisombululo kukujonga ukuba loo nto yomile, ukuqinisekisa ukuba akukho nkozo okanye i-vula i-vula. Kwangelo xesha, unokwandisa ngokufanelekileyo ubushushu obubumba kunye neqondo lokushisa, ukwandisa ixesha elinenaliti kunye nenaliti, ukuze uvumele izinto ezenziwa ngcono kwaye zigcwalise i-movity cavity.

5.Ukubonakala kwe-opacity okanye umbala ongahambelaniyo

Kungenxa yomgangatho weengxaki ze-PPSU, isisombululo kukujonga ukuba ngaba izinto zifanelekile, ukuba kukho ingxaki yokutshintshwa ngexesha elifanelekileyo. Kwangelo xesha linye ukuba kufanelekile ukwandisa ubushushu bokulungisa kwaye kwandise ixesha lokuqhuba, ukwenzela ukuba iplastiki engcono kunye nokuxuba iyunifomu.
