Imibuzo esibhozo ekufuneka uyithathele ingqalelo xa kutofwa ibhotile ye-PET embryo

1. Unyango lweplastiki

Ngenxa yokuba i-PET macromolecules iqulethe amaqela e-lipid kwaye ineempawu ezithile ze-hydrophilic, ingqolowa ivakalelwa kumanzi kwiqondo lokushisa eliphezulu.Xa isiqulatho samanzi sidlula umda, ubunzima bemolekyuli be-PET buyancipha ekusebenzeni, kwaye iimveliso ziba nombala kwaye zibe brittle.
Ngoko ke, ngaphambi kokucutshungulwa, izinto kufuneka zomiswe, kunye nokushisa kokumisa kwe-150 ℃, ngaphezu kweeyure ze-4;ngokubanzi 170℃, 3-4 iiyure.Indlela yomoya ingasetyenziselwa ukuvavanya ukomisa ngokupheleleyo.Umyinge wezinto zokuphinda zisetyenziswe kwibhotile ye-PET billet akufuneki ugqithe kwi-25%, kwaye izinto ezisetyenzisiweyo kufuneka zomiswe kakuhle.

2. Ukukhethwa komatshini wokubumba inaliti

Ngenxa yokuba i-PET inexesha elifutshane elizinzile emva kwendawo yokunyibilika kunye neqondo eliphezulu lokunyibilika, kuyimfuneko ukukhetha inkqubo yokutofa kunye namacandelo amaninzi okulawula ubushushu kunye nokunciphisa ukuzimela kunye nokuvelisa ukushisa ngexesha leplastiki, kunye nobunzima bokwenene bemveliso (kubandakanywa imathiriyeli yokuthatha amanzi) akufanele ibe ngaphantsi kwe-2/3 yesixa sokutofa komatshini.

3. Umngundo kunye noyilo lwesango lokugalela

I-embryo yebhotile ye-PET, ngokubanzi eyenziwe ngokubumba komjelo wokuhamba kobushushu, i-mold kunye ne-injection yomatshini wokubumba itemplate phakathi kokungcono ukuba ne-plate yokufaka ukushisa, ubukhulu bayo bumalunga ne-12mm, kwaye ipleyiti yokushisa ukushisa kufuneka ikwazi ukumelana noxinzelelo oluphezulu.Umbhobho kufuneka wanele ukunqanda ukushisa okugqithisileyo okanye ukuqhekeka kwendawo, kodwa ubunzulu be-exhaust port ngokubanzi abudluli kwi-0.03mm, kungenjalo kulula ukuvelisa icala elibhabhayo.

4. Ubushushu obunyibilikayo

Umlinganiselo wendlela yokukhutshwa komoya ekhoyo, 270-295℃ uluhlu, ibakala eliphuculweyo le-GF-PET linokusetwa kwi-290-315℃, njl.

5. Isantya senaliti

Isantya senaliti jikelele kufuneka sikhawuleze ukuthintela ukujiya kwangaphambi kwexesha ngexesha lokutofa.Kodwa ngokukhawuleza, izinga lokucheba liphezulu, yenza ukuba izinto eziphathekayo zibe buthathaka.Ukudubula kudla ngokugqitywa kwimizuzwana emi-4.

6. Uxinzelelo lwangasemva

Okusezantsi kungcono, ukuphepha ukunxiba.Ngokubanzi ayidluli kwi-100bar, ayidli ngokusetyenziswa.

7. Ixesha lokuhlala

Musa ukusebenzisa ixesha elide logcino ukunqanda ukuhla kobunzima bemolekyuli, kwaye zama ukunqanda ubushushu obungaphezulu kwe-300℃.Ukuba ukuvalwa kungaphantsi kwemizuzu eyi-15, yenza kuphela unyango lokudubula emoyeni;ukuba ngaphezu kwemizuzu eyi-15, ke uhlambulule nge-viscosity PE, kwaye ulahle ubushushu be-cylinder kwiqondo lokushisa le-PE, de uqalise kwakhona.

8. Izilumkiso

Izinto zokubuyisela kwakhona azikwazi ukuba zikhulu kakhulu, ngaphandle koko, kulula ukuvelisa kwizinto "ibhulorho" kwaye zichaphazela iplastiki;
Ukuba ulawulo lobushushu lokungunda alulungile, okanye ulawulo lobushushu bezinto eziphathekayo alufanelekanga, kulula ukuvelisa "inkungu emhlophe" kunye ne-opaque;ubushushu bomngundo buphantsi kwaye bufana, isantya sokupholisa ngokukhawuleza, i-crystallization encinci, emva koko imveliso ibonakala.

I-Huangyan Leiao Molding Co., Ltd. ikwidolophu yokubumba yeSithili saseHuangyan, eTaizhou, kwiphondo laseTaizhou, eli "Idolophu yasekhaya yaseTshayina".Inkampani ibandakanyeka ikakhulu kwimveliso yokubumba inaliti, ineminyaka emininzi yamava okungunda, ikakhulu imveliso kunye nokusetyenzwa kwe-ebryo mold yebhotile, i-PET commodity mold, i-bottle cap mold, ingaphakathi lemoto kunye nomphandle wokuhombisa wangaphandle… … Inkqubo yokubumba inoyilo lwayo olulodwa kunye neteknoloji yokucubungula, esekelwe kwingcamango "yolawulo lweMfezeko", kunye nabathengi basekhaya nabangaphandle ukuseka ubudlelwane obuhle bexesha elide lentsebenziswano, ndiyakholelwa ukuba uLeiao uya kufaneleka ukuzithemba kwintsebenziswano. ishishini.
