Inkqubo yokubumba izinto zeplastiki zokupakisha kushishino lwezithambiso yahlulwe kakhulu ibe ziindidi ezimbini: ukubumba inaliti kunye nokuvuthela.

Isitofu sokubumba

Yintoni inkqubo yokubumba inaliti?

Isitofu sokubumba yinkqubo yokufudumeza kunye neplastiki yeplastiki (ukufudumeza kunye nokunyibilika kulwelo, iplastiki), kwaye emva koko ifake uxinzelelo lokuyitofa kwindawo yokubumba evaliweyo, ukuvumela ukuba kuphole kwaye kuqiniswe kubumba, ukuvelisa imveliso nge imilo efanayo nokungunda.Ifanelekile kwimveliso yobuninzi beengxenye ezinemilo enzima.

Iimpawu zenkqubo yokubumba inaliti:

1. Isantya sokuvelisa ngokukhawuleza, ukusebenza kakuhle okuphezulu, izinga eliphezulu lokuzenzekelayo kokusebenza

2. Imveliso inokuchaneka okuphezulu, kwaye impazamo yokubonakala incinci kakhulu

3. Ukwazi ukuvelisa iindawo ezinemilo enzima

4. Iindleko eziphezulu zokungunda

Uninzi lwethuibhotile engenamoya, ibhotile yokuthambisa enodonga oluphindwe kabiniziveliswa ngenkqubo yokutofa.

Ukubumba ukuvuthela

Iimpawu zenkqubo yokubumba ukuvuthela:

Ukuzoba izifundo ezivela kwinkqubo yokuvuthela yeglasi, ukuvuthela kusebenzisa umoya ocinezelweyo kunye noxinzelelo oluthile lokufunxa kunye nokupholisa i-preform (umzimba weplastiki we-tubular ogqityiweyo ogqityiweyo) kwi-mold ibe yinkqubo yokubumba imveliso engenanto.Ilungele ukuveliswa kwezinto ezininzi zeplastiki ezingenanto.

Zeziphi iimpawu zenkqubo yokubumba isivuthelo?

1. Indlela yokuvelisa elula, ukusebenza kakuhle kwemveliso kunye nokuzenzekelayo

2. Ukuchaneka kwe-dimensional ephantsi

3. Kukho izithintelo ezithile kwimilo yemveliso

4. Ixabiso eliphantsi lokungunda

Ngokwamanyathelo ahlukeneyo emveliso kunye neenkqubo, ukubumba ukuvuthela kunokohlulwa kube ziindidi ezintathu: ukuvuthela nge-extrusion, ukuvuthela ngesitofu, kunye nokuvuthela ngenaliti.

Eyokuqala kukukhama nokuvuthela.Njengoko igama libonisa, ukuvuthela kwe-extrusion kunamanyathelo amabini amakhulu: i-extrusion kunye ne-blow molding.

Inyathelo lokuqala kukwandisa ukuvalwa komngundo.Isixhobo se-extrusion siyaqhubeka ukukhama ukwenza i-parison ye-tubular engenanto.Xa i-parison ikhutshwe kwi-predetermined ubude, umphezulu we-parison unqunyulwe ubude obufanelekileyo kwisiqwenga esisodwa, kunye nokubunjwa kumacala asekhohlo nasekunene avaliwe.

Inyathelo lesibini, ukungenisa umoya-ukunciphisa.Umoya oxinanisiweyo utofwe kwi-preform ngokusebenzisa i-mandrel ukuvuthela.I-parison ibambelela ngokusondeleyo kwindonga yangaphakathi yobumba ukuze ipholile kwaye ibumbe, kwaye imveliso isuswe kwi-mold, kwaye i-trimming yesibini yenziwa.Iindleko ze-extrusion kunye nezixhobo zokuvuthela kunye nokubumba ziphantsi, kwaye iindleko zemveliso nazo ziphantsi.

Nangona kunjalo, ukudanyaza kwenzeka ngexesha lenkqubo yokuvelisa, kwaye umlomo kunye nomzantsi webhotile kufuneka ulungiswe ngomatshini okanye ngesandla, kwaye ngamanye amaxesha umlomo webhotile kufuneka upholiswe kwaye ulungiswe.

Iibhotile zeplastiki ezibunjiweyo ezibunjiweyo zinomgca wokuqhawula (i-linear protrusion) ezantsi, kwaye umlomo webhotile urhabaxa kwaye awugudi, ngoko ke abanye banomngcipheko wokuvuza kolwelo.Iibhotile ezinjalo zihlala zenziwe ngezinto ze-PE kwaye zisetyenziselwa izimonyo ezifana neebhotile ze-foam, i-lotions yomzimba, i-shampoos kunye ne-conditioners.

Uhlobo lwesibini kukuvuthela inaliti, enamanyathelo amakhulu amabini: ukubumba ngesitofu.

Inyathelo loku-1: Ukuvalwa kwangaphambili kwesitofu sokungunda.

Sebenzisa inkqubo yokubumba inaliti ukuvelisa i-parison ephantsi, kwaye i-console ijikeleza i-120 ° kwikhonkco lokubumba.

Umngundo ivaliwe, kwaye umoya zixinaniswe wangeniswa kwi parison ngokusebenzisa pores mandrel ukuvuthela ukubumba.

Inyathelo lesi-2: Lungiselela kwangaphambili ukunyuka kwamaxabiso-okupholisa kunye nokunciphisa.

Emva kokuba imveliso evuthelweyo iphiliswe ngokupheleleyo kwaye ibunjwe, i-console ijikeleza i-120 ° ukudiliza imveliso.Akukho mfuneko yokulungisa okwesibini, ngoko ke iqondo lokuzisebenzela kunye nokusebenza kakuhle kwemveliso kuphezulu.Ngenxa yokuba ibhotile ivuthelwa kwiparison eyenziwe ngenaliti, umlomo webhotile usicaba kwaye ibhotile ineempawu ezingcono zokutywina, ezinje ngeTB07 ukuvuthela ibhotile series.

Uhlobo lwesithathu lutsalo kunye nokuvuthela.Yahlulahlulwe yangamanyathelo amathathu: isitofu-ukuzolula-ivuthelo lokubumba.

Ngokwahlukileyo kuhlobo olujikwayo lwenaliti evuthelayo, ukuvuthela ngenaliti yolula yimveliso yomgca wokuhlanganisa.

Inyathelo loku-1: Ukuvalwa kwangaphambili kwesitofu sokungunda

Beka i-preform eveliswe ngesitofu kwi-mold yokuvuthela

Faka intonga yokwelula kwaye uvale isikhunta ngasekhohlo nasekunene

Inyathelo lesi-2: Ukolula-Ukuvuthela-Ukupholisa kunye nokudiliza

Intonga eyoluliweyo yoluliwe ngokokude, ngelixa umoya utofwa ngentonga yokwelula ukuze ulule icala.

Ukupholisa kunye nokubumba, ukudiliza kunye nokukhupha imveliso

Isitofu esolula sokuvuthela ngowona mgangatho uphezulu, ukuchaneka kunye neendleko kwinkqubo yokubumba.

Okwangoku, kukho iindlela ezimbini zokuvelisa kwinkqubo yokuvuthela yolula inaliti, ebizwa: indlela enenyathelo elinye kunye nenqanaba elinye.Ukubunjwa kwe-injection kunye nokuvuthela kugqitywe kunye kwindlela yesinyathelo esinye, kwaye amanyathelo amabini agqitywe ngokuzimeleyo njengendlela yamanyathelo amabini.

Xa kuthelekiswa nendlela yamanyathelo amabini, indlela yesinyathelo enye igqitywe kwisixhobo esinenyathelo elinye ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo.Inkqubo yokuvelisa ilula kwaye akukho ukufudumeza kwesibini kuvunyelwe, ngoko ukusetyenziswa kwamandla kuphantsi.

Indlela enamanyathelo amabini ifuna inaliti ye-preform yokuqala, kwaye emva koko iprosesa yesibini kumatshini wokubumba.Ukubumba ukuvuthela kufuna ukufudumeza okwesibini kwe-preform epholileyo, ngoko ke ukusetyenziswa kwamandla kuphezulu.

Uninzi lolwazi luvela kwikhonkco lokubonelela ngobuhle beCiE
