I-Extrusion ingaba yindlela yokuvelisa apho i-vinyl inyibilika kwaye ifakwe kwiprofayili. I-Extrusion ihambisa izinto ezifana nokuhluthwa kwemozulu, iityhubhu, ukubiyela, iintsimbi zomngangatho, imifanekiso yefreyimu yefestile kunye neengubo zokugquma, kunye nemathiriyeli yokugquma intambo.

Le nkqubo ilandelayo iqalisa ngokutya izinto zeplastiki (imidumba, iigranule, umgubo okanye izitshizi) ngaphandle kwehopper ukuya kwidama le-extruder. Eli laphu liye lacudiswa imijelo ngombane ngokujika izikrufu ezenziweyo.
Izinto eziqhelekileyo ze-Extrusion

Ziquka kodwa aziphelelanga kwiPVC, PP, PC, PE kunye ne-ABS (acrylonitrile butadiene styrene)
Iimodeli zeDie

Kukho kusoloko kukho inani lokufa. Zonke iifa zivumela endaweni yokungaqhubeki nokuqhubekeka njengokubumba inaliti ngelixa kunokubakho umahluko phakathi kobuchule kunye neentlobo.
Iphepha Extrusion

I-Sheet extrusion isebenzisa amaphepha eplastiki akhuphayo okanye iifilim ezishinyene kakhulu ukuba zingavuthelwa. Ukongeza, kukho iintlobo ezimbini zokufa: i-T-shape kunye ne-hanger yedyasi. Isikhokelo kunye nenjongo yokufa zihlala zilungelelanisa umsinga weplastiki enyibilikayo kwimveliso enye engqukuva nge-extruder yakho ukuya kwintshukumo ethile yeplani.

Rhoqo i-co-extrusion inokusetyenziselwa ukuqesha iileya ezimbalwa ngaphezulu kwelaphu lesiseko ukufumana izinto ezithile ezinje ngokufunxa kwe-UV, ukuchasana nokungena kweoksijini, okanye ukubonakaliswa kwamandla.

pc umgca wentsimbi umgca wokukhupha

Ikhosi yesiqhelo ye-post-extrusion yesenzo se-vinyl sheet inventory yi-thermoforming. Enyanisweni, iphepha liphantsi kweemeko ezifudumeleyo kude kube yithenda (vinyl), kunye nokuqulunqwa usebenzisa i-mildew kwifom entsha. Yivacuum leyo. Emva kokuba ivacuum isetyenzisiwe, uqhelaniso lubaluleke kakhulu kwaye lunempembelelo enkulu ekubunjweni kwamathuba omjikelezo ngenxa yeentsimbi ezininzi.
Ukuvuthela Extrusion

Ukuveliswa kwe-vinyl membrane ukufumana izinto ezifana ne-sheeting kunye nemithwalo yokuthenga. Ifezekisa ngokuqesha umgca we-membrane ovuthelweyo.

50/100/160 Umaleko oMbini uVuthela uMshini wokuBumba

Ngaphambi kokushiya ixesha lokuhambisa i-tubing kukupholisa ukunyibilika. Idayamitha yayo iye yandiswa ngoxinzelelo lwe-atmosphere, kwaye ityhubhu iye yatsalwa phezulu ngeepliers, yandisa iplastiki ekutsaleni imiyalelo kunye neretina. Umzobo ukwathelekisa amatyathanga epolymer, nawo uvuthela inwebu ukuba ibe nkulu xa kuthelekiswa netyhubhu yegrunt. Kwimeko apho umboniso bhanyabhanya utsalwe umdla kakhulu ngakumbi kunoko uvuthelwe ngokwenene (ukuba ityhubhu yokugqibela idayamitha isondele kakhulu kwidayamitha ephakathi) iimolekyuli ze-aluminiyam mhlawumbi ziya kulungelelaniswa ngokumangalisayo kusetyenziswa lonke ulawulo lokuzoba, ukwakha ifilimu eyomeleleyo ngale ndlela, nangona ibuthathaka ukusuka kwindlela elungileyo. Inwebu yedayamitha enkulu xa ithelekiswa nedayamitha ephakathi iya kuba namandla kulawulo oluchanekileyo, kodwa hayi ukusuka kulawulo lomtsalane.

Iyatsala umdla wokuyithunga ibe ityhubhu elele-caba, enokuthi igxunyekwe okanye iphoswe kubuncinci iibhithi ezimbini zeplywood, ngelixa inwebu iqhubeka nokuphola.
Ukwaleka Extrusion

Idyasi ye-Extrusion okwangoku inesaphulelo okanye indlela yefilimu ephosiweyo. Ezi ndlela zimbini zijolise ekufakeni i-coating eyongezelelweyo kwi-rollstock yephepha elicacileyo okanye ifilimu. Ngokomzekelo, le nkqubo inokusebenzisa i-coating. Ngoko ke ukwenza ukuxhathisa ukuba namanzi ukunyusa iimpawu zephepha. Umaleko usenokusetyenziselwa ukutsala izinto ezi-2.
Extruder Category

Kukho nje ezinye iintlobo ezimbini ze-screw extruders. Ulawulo isikrufu ngasinye sisonta xa sithelekisa nesinye sibiza ngolu hlobo lwegama. Zombini izikrufu zijijwa ngokwewotshi okanye ngasekunene. Kungqiniwe ukuba, kwindawo enqamlezileyo enikiweyo kunye nenqanaba lokuhlangana, isantya se-axial kunye nenqanaba lokuxuba likhulu kwi-co-rotating dual extruders. Ukwakhiwa koxinzelelo kukhulu kwi-extruders. Uyilo lwe-twist kukuloo macandelo okuxuba kunye nokuhambisa. Oku kukulungiselela ukuvumela uhlengahlengiso lwemodyuli ukufumana ukutshintshwa okanye uhlengahlengiso lwenkqubo yamalungu ngenxa yokuguga okanye umonakalo ongenakulungiseka.

Inkqubo yePlastiki Extrusion

Ukusuka kwi-extrusion yeeplastiki, izixhobo zeekhemikhali zokuhlenga zihlala luhlobo lwee-nurdles, zihlala zibhekisela njenge-resin, enokuthi ivumele ukupompa nge-hopper ephezulu kwi-reservoir ye-extruder. Ilaphu lidlula ngendlela yokutya (ivula kufutshane nomva wombhobho) kwaye liza lidityaniswe ngokuthe ngqo nawo wonke umsonto wokujija. Ubunzima kunye nomhlwa kubangela ukufudumala okungakumbi. Kwinxalenye ekhokelayo yekhowuni, i-vinyl ekhuselweyo ihamba ukuphelisa naluphi na ungcoliseko kwaye ishiya i-twist. ingena ekupheleni emva kokuhamba kuyo yonke ipleyiti yebreaker. Into idinga ukuphola phantsi ngokutsala i-extrudate kwaye iqonde.
Izinto eziluncedo zePlastiki Extrusion
ngendleko ephantsi

Ngokuchaseneyo neenkqubo zokubumba ezongezelelweyo zokubumba i-extrusion inokuthenjwa kakhulu kwaye iza nexabiso. Nkqu inkqubo ye-extrusion isebenzisa i-thermoplastics kunye nabo bafumana ukunyibilika kunye nokuntlitheka. Iindleko zokulahla kunye nezinto ezikrwada zonke ziphantsi. Izixhobo ze-compound extrusion ziyasebenza kwaye oku kunciphisa ukubakho kokusilela kwempahla.
Isantya esiphakamileyo

Inkqubo ye-extrusion ivelisa kwaye ikhawuleza ekuveliseni iikhonto ngobude. Iinkonzo kunye neemveliso zinokwenziwa ngobuninzi, kwaye kukho inkcitho encinci.
