Ukukhipha kungaba yindlela yokukhiqiza lapho i-vinyl incibilikiswa khona bese ibunjwa ibe yiphrofayili. Ukukhipha kuletha izinto ezifana nokususa isimo sezulu, ukuthungwa kwamapayipi, uthango, izindonga zamadekhi, izithombe zozimele zamafasitela kanye nokufakwa kwamashidi, kanye nezinto zokuvikela ikhebula.

Inqubo elandelayo iqala ngokudla izinto zepulasitiki (ama-legume, ama-granule, ama-powder noma ama-spray) zisuka e-hopper ziye endaweni yokugcina amanzi. Le ndwangu icindezelwe ngamapayipi kagesi ngokuphendula izikulufo ezenziwe.
Izinto Ezivamile Zokukhipha

Yakhiwe kodwa ayikhawulelwe ku-PVC, PP, PC, PE kanye ne-ABS (acrylonitrile butadiene styrene)
Amamodeli Okufa

Kuhlala kukhona inani lama-dies. Wonke ama-dies avumela esikhundleni sokucutshungulwa okungaqhubeki njengokubumba ngomjovo kuyilapho kungase kube nomehluko phakathi kobuchwepheshe nezinhlobo.
I-Extrusion Yeshidi

Ukukhishwa kweshidi kusebenzisa amashidi epulasitiki noma ngisho namafilimu aqinile kakhulu ukuba angapheshulwa. Ngaphezu kwalokho, kunezinhlobo ezimbili zamadayi: i-T-shape kanye ne-coat hanger. Umhlahlandlela kanye nenhloso yamadayi njalo ukuhlela kabusha ukugeleza kokuncibilika kwepulasitiki okuvela kokukhipha okukodwa okuyisiyingi yi-extruder yakho kuya ekunyakazeni okuhleliwe.

Ngokuvamile i-co-extrusion ingasetshenziswa ukusebenzisa izendlalelo ezimbalwa phezu kwendwangu eyisisekelo ukuthola izinto ezithile ezifana nokumuncwa kwe-UV, ukumelana nokugeleza komoya-mpilo, noma ukubonakaliswa kwamandla.

Indlela evamile yokusebenza ngemva kokukhipha izinto ze-vinyl sheet iwukwenza i-thermoforming. Eqinisweni, ishidi liba ngaphansi kwezimo ezifudumele kuze kube yilapho lithambile (i-vinyl), futhi libumbeke kusetshenziswa isikhunta sibe uhlobo olusha. Lokho kuyi-vacuum. Uma i-vacuum isisetshenzisiwe, ukuqondisa kubaluleke kakhulu futhi kuthinta kakhulu ukwakheka kwezikhawu zomjikelezo ngenxa yezinsimbi eziningi.
Ukuqhuma Okuphumayo

Ukukhiqizwa kwe-vinyl membrane ukuze kutholakale izinto ezifana ne-sheeting kanye nemithwalo yokuthenga. Kusebenza kahle ngokusebenzisa umugqa we-membrane ovuvukile.

Umshini Wokubumba Owenziwe Ngezingqimba Ezimbili Ongama-50/100/160

Ngaphambi kokuphuma isikhathi sokuphelelwa yisikhathi, ipayipi lipholisa ukuncibilika. Ububanzi balo bukhulisiwe ngenxa yokucindezeleka komoya, futhi ipayipi lidonswe phezulu nge-pliers, okwandisa ipulasitiki ekudonseni imiyalelo kanye ne-retina. Umdwebo uphinde uqhathanise amaketanga e-polymer, futhi ukushaya kubangela ulwelwesi ukuba lube luncane kakhulu kunepayipi lokubhodla. Uma ifilimu idonswa kakhulu kunalokho okupheshulwa (ukuthi ububanzi bokugcina bepayipi buseduze nobubanzi obuphakathi) ama-molecule e-aluminium azohlanganiswa kahle ngokusebenzisa yonke inqubo yokudonsa, kwakhiwe ifilimu eqinile ngale ndlela, kodwa ibuthakathaka endleleni efanele. I-membrane enobubanzi obukhulu kunobubanzi obuphakathi izoba namandla avela ohlelweni olufanele, kodwa hhayi njengolawulo lokudonsa.

Iyakhangwa ukuyithungela epayipini eliyisicaba, elingaxutshwa noma lifakwe okungenani izingcezu ezimbili ze-plywood, kuyilapho ulwelwesi luqhubeka luphola.
Ukwemboza Okungeziwe

Ijazi lokukhipha okwamanje linendlela yokunciphisa noma yokwenza ifilimu. Lezi zindlela ezimbili zihlose ukumboza ungqimba olwengeziwe ephepheni noma ifilimu ecacile. Isibonelo, le nqubo ingasebenzisa ungqimba. Ngakho-ke iyenza imelane namanzi ukuze ithuthukise izici zephepha. Isendlalelo singase sisetshenziselwe ukuheha izinto ezimbili.
Isigaba Sokukhipha Izinto Ezingaphandle

Kunezinhlobo ezimbili nje ze-screw extruders. Ukuphathwa kwe-screw ngayinye ejikeleza uma iqhathaniswa nenye kubiza ngale ndlela yokuqamba amagama. Zombili izikulufo zijika ngokwewashi noma ngokuphambene newashi. Kufakazelwe ukuthi, endaweni ethile enqamulayo kanye nezinga lokugqagqana, isivinini se-axial kanye nezinga lokuxuba kukhulu kuma-extruders amabili ajikelezayo. Ukwanda kwengcindezi kukhulu kuma-extruders. Ukwakheka kokujika kukulezo zingxenye zokuxuba nokudlulisa. Lokhu kwenzelwa ukuhlela ukuvumela ukulungiswa kabusha kwe-modular ukuthola ukushintshwa noma ukuguqulwa kwenqubo yezingxenye ngenxa yokuguguleka noma umonakalo ongenakulungiswa.

Inqubo Yokukhipha Ipulasitiki

Kusukela ekukhishweni kwepulasitiki, izinto zamakhemikhali eziphumayo zivame ukuba uhlobo lwe-nurdles, ezivame ukubizwa ngokuthi i-resin, engadedelwa yi-hopper efakwe phezulu iye endaweni yokugcina i-extruder. Indwangu idlula endaweni yokudla (imbobo eduze kwangemuva komgqomo) futhi ixhumene ngqo nayo yonke intambo egobile. Ukucindezeleka nokugqwala kunikeza ukufudumala okwengeziwe. Engxenyeni eyinhloko yekhoni, i-vinyl egobile iyahamba ukuze isuse noma yikuphi ukungcola futhi ishiye i-twist. ingena ekupheleni kokuphela ngemva kokuhamba kuyo yonke ipuleti le-breaker. Into idinga ukupholisa ngokudonsa i-extrudate bese ifinyelela.
Izinzuzo Plastic Extrusion
eziphansi

Ngokungafani nezinqubo ezengeziwe zokubumba, ukubumba kwe-extrusion kungaba okuthembekile kakhulu futhi kuza nentengo ephansi. Ngisho nenqubo ye-extrusion isebenzisa ama-thermoplastics futhi ahlangabezana nokuncibilika nokuthuthumela. Izindleko zokulahla nezinto zokusetshenziswa zonke ziphansi. Amadivayisi e-compound extrusion ayasebenza futhi lokhu kunciphisa amathuba okuntuleka kwesitoko.
Ijubane Eliphakeme

Inqubo yokukhipha insimbi iyasebenza futhi iyashesha ekukhiqizeni ama-contours ngobude. Izinsizakalo nemikhiqizo kungenziwa ngobuningi obukhulu, futhi kukhona ukuchithwa okuncane.
