Taw qhia rau tshuab moulding tshuab

Tshuab moulding tshuab rau cov khoom siv yas yas. Lub tshuab tshuab moulding tuaj yeem plasticize cov khoom preformed los ntawm cua sov, thiab tom qab ntawd nkag mus rau cov pwm rau tshuab molding. Txoj kev no tsuas yog siv rau kev tsim cov raj mis PET thiab BOPP lub raj mis nrog kev kub ceev thiab cov zis siab, uas yog, txheej txheem ob-kauj ruam; Tshuab moulding kuj tseem tuaj yeem ua ke nrog cov txheej txheem txhaj tshuaj molding los ua lub tshuab txhaj tshuaj-draw-blowing, uas kuj yog ib txoj hauv kev tsim cov ntim hauv PET; Cov txheej txheem tshuab moulding kuj tuaj yeem ua ke nrog cov txheej txheem extrusion. Daim ntawv thov ntawm cov khoom siv extrusion tshuab moulding yog dav dua, thiab cov khoom uas tuaj yeem tsim tau ntau dua. Cov khoom lag luam suav nrog ntau txheej txheej zaj duab xis thiab ntau yam polyolefin hollow ntim, uas tau siv dav hauv kev lag luam khoom noj, tshuaj thiab tshuaj pleev ib ce.

Tshuab tshuab moulding tuaj yeem muab faib ua peb pawg: tshuab extrusion tshuab moulding tshuab, tshuab tshuab moulding tshuab thiab tshwj xeeb qauv tshuab tshuab moulding tshuab. Stretch tshuab moulding tshuab tuaj yeem muab faib ua txhua yam saum toj no. Extrusion tshuab moulding tshuab yog kev sib xyaw ntawm extruder, tshuab moulding tshuab thiab tuag kaw mechanism, uas yog tsim los ntawm extruder thiab dawb paug tuag lub taub hau, tshuab expansion tshuab, tuag kaw mechanism, dawb paug thickness tswj system thiab kis mechanism. Cov tuag dawb paug yog ib qho tseem ceeb ntawm cov khoom uas txiav txim siab qhov zoo ntawm cov tshuab molding khoom, feem ntau suav nrog rau sab pub tuag thiab qhov chaw pub tuag. Lub tog raj kheej cia hom dawb paug tuag lub taub hau feem ntau yog siv rau cov khoom loj thaum tshuab molding. Qhov tsawg kawg nkaus ntim ntawm lub tank yog 1kg thiab qhov siab tshaj plaws ntim yog 240kg. Lub parison thickness tswj ntaus ntawv yog siv los tswj lub parison phab ntsa thickness. Qhov siab tshaj plaws tswj taw tes yog 128 ntsiab lus, feem ntau 20 ~ 30 ntsiab lus. Lub tshuab extrusion tshuab tuaj yeem tsim cov khoom hollow nrog lub ntim ntau ntawm 2.5ml ~ 104l.

Raws li lub raj mis tshuab tshuab, lub tshuab txhaj tshuaj molding tshuab yog kev sib xyaw ua ke ntawm kev txhaj tshuaj molding tshuab thiab tshuab moulding tshuab, suav nrog cov tshuab yas, hydraulic system, tswj cov khoom siv hluav taws xob thiab lwm yam khoom siv tshuab. Cov hom muaj xws li peb-chaw nres tsheb txhaj tshuaj tshuab moulding tshuab thiab plaub-chaw nres tsheb txhaj tshuab moulding tshuab. Lub tshuab peb-chaw nres tsheb muaj peb qhov chaw nres tsheb rau preforming, tshuab thiab demoulding, txhua qhov sib cais los ntawm 120 degree. Lub tshuab plaub-chaw nres tsheb muaj ntau qhov chaw ua ntej, txhua qhov sib cais los ntawm 90 degree. Tsis tas li ntawd, muaj dual-chaw nres tsheb txhaj tshuaj molding tshuab nrog 180 degree ntawm chaw nres tsheb. Cov thawv yas tsim los ntawm kev txhaj tshuaj molding tshuab yog qhov loj thiab tsis xav tau kev ua haujlwm thib ob, tab sis tus nqi pwm yog siab.

Cov qauv tshwj xeeb tshuab moulding tshuab yog lub tshuab moulding tshuab uas siv cov ntawv, cov khoom siv molten thiab txias dawb li parison los tshuab pwm hollow lub cev nrog tshwj xeeb zoo thiab lub hom phiaj. Vim muaj cov duab sib txawv thiab cov kev xav tau ntawm cov khoom tsim, cov qauv ntawm lub tshuab tshuab moulding kuj txawv.
