Tsiaj Ntawv Extrusion Tshuab Kab

Tsiaj (polyethylene terephthalate) cov ntawv txheeb (amorphous ntim, thiab lwm yam khoom siv cov khoom siv noo, thiab lwm yam kub thiab txias, cov Cov khoom siv muaj nws cov qauv tshwj xeeb thiab cov tseev kom muaj.

 

 

Qhov loj tshaj plaws ntawm tus tsiaj yog:

1. Hygroscopic: thaum tsiaj raw cov ntaub ntawv yog ua tiav thaum hydrolyze, ua rau molecy, ua rau cov tshuaj ntxuav kom huv si hauv cov khoom siv tshuab ntawm cov khoom lag luam. Yog li ntawd, lub tshuab ziab khaub ncaws yog txoj sia ntawm cov tsiaj ntau lawm.

2. Pom tseeb crystallization tus cwj pwm: yuav tsum ceev ceev thaum lub sijhawm ua kom tiav centstallization thiab tsim cov ntawv txheeb APET APET cov ntaub ntawv zoo heev; Lwm txoj kev hloov kho, cua sov tuaj yeem txhawb kev siv cov cua sov - ionistant cpet cov ntawv (xws li qhov cub tais).

 

 

Tus qauv tsiaj extrusion cov kab ntau yog suav nrog cov hauv qab no:

1. Cov khoom lag luam pretrepleatment system - qhov tseem ceeb tshaj plaws

· DehetheCidification thiab Drying System:

· Cov khoom tseem ceeb: muaj tsawg kawg yog ob muv log dehumidifiers thiab tshuab ziab khaub ncaws.

· WorkFlow: Qhov no yog kev nruam cov txheej txheem. Lub tshuab ziab khaub ncaws ua haujlwm tsis tu ncua rau cov tsiaj raw (feem ntau yog hauv granular daim ntawv) tsawg kawg yog 46 teev, txo cov ntsiab lus ya raws qib siab rau hauv qab 50ppm (0.005%) (feem ntau xav tau<30ppm). The other one is used as a backup or regeneration to ensure uninterrupted production.

Lub tshuab nqus nqus system: Cov ntaub ntawv qhuav tau ncaj qha rau hauv extruder hopper los ntawm kev nqus cov tshuab nqus hluav taws xob kom tsis txhob muaj kev nqus kom noo ntxiv.

 

2. Extrusion Txheej Txheem

Extruder:

Ib leeg ntsia hlau tso rau extruder: qhov no yog tus qauv teeb tsa rau tsiaj ntawv ntau lawm.

Vim li cas sab laj kev sab? Txawm hais tias cov ntaub ntawv nyoos tau qhuav, ib qho nyiaj me me ntawm cov roj uas muaj roj me me (noo noo, oligomers) tseem yuav tsim tawm thaum lub sij hawm melting. Lub tso sab tso tawm yog nruab nrog lub zog thiab txuas nrog lub tshuab nqus tsev, uas tuaj yeem yuam kom cov roj av, kom cov khoom kawg yog npuas thiab tsis muaj kev cuam tshuam dawb.

Screw Design: tshwj xeeb tsim rau lub viscosity, melting point, thiab lwm yam piv txwv ntev), xws li ib qho ntev dua, los xyuas kom meej me ntsis thiab homogenization.

· Ntshai lim thiab twj tso kua mis (yeem tab sis tseem ceeb):

· Qhuav lim: tshwj xeeb tshaj yog thaum siv rpet (siv cov khoom siv rov qab), nws yog siv los lim impurities thiab carbide hais nyob rau hauv cov yaj.

· Mole zaub twj tso kua mis: nruab nrab ntawm Extruder qhov hluav taws xob thiab cov tuag lub taub hau, thiab ua kom ultre hloov ntsia hlau pulses, thiab ua kom ultras zoo nkauj ntawm daim ntawv tuab. Nws yog qhov tseem ceeb ntawm kev xaiv rau kev tsim cov siab -} ntawv cov ntaub ntawv.

El Limy Lub taub hau:

· Poj niam hom t - zoo li tus tsiaj dig rau hauv pvc daim hlau xaim mus rau hauv cov kab ntsig ntawm qhov xav tau dav thiab tuab. Cov Channel tsim nyog yuav tsum hloov mus rau cov lus ntawm tus tsiaj. Lub cev nqaij daim di ncauj feem ntau yog nruab nrog lub qhov ntsuas kub kub kub kub transmressment kev hloov kho rau hauv online zoo kho cov ntawv ntawm daim ntawv.

 

3. Daim Duab Thiab Txias Zog

Peb ob leeg calender:

· Cort txoj kev ua hauj lwm: Rau tus tsiaj, txoj haujlwm tseem ceeb ntawm peb chais yog sai sai txias. Lub siab - kub (kwv yees li 280℃c)

Cov tub rog cov tub rog tswj qhov kub thiab txias: peb cov menyuam yaus tau muab ib feem ntau yog npaj ntsug lossis ntawm 45℃kaum. Cov menyuam nruab nrab yog cov menyuam nruab nrab, thiab sab saud thiab qis dua yog cov ntaub qhwv tau yooj yim. Muaj cov dej txias tas li hauv cov menyuam, thiab ntsuas qhov kub thiab txias.

· Deg deg deg deg: Siv daim iav chais tuaj yeem txais cov ntawv du, thaum siv cov zaub frosted tuaj yeem tsim cov ntawv matte.

 

4. Traction, thickness ntsuas thiab cua tshuab cua

· Tetaction Chav Tsev: Ua kom muaj cov txiv hmab ntau dua thiab cov roj hmab traction chais, nws tau yooj yim rau ntawm peb cov menyuam lub tshuab thiab txuas ntxiv nws.

· Online thickness thibe kawg (beta ray los yog infrared): thaum tsis muaj qhov tseeb ntawm daim ntawv thiab muab cov lus qhia tiag tiag ntawm cov ntaub ntawv tuab. Cov kab ke no tuaj yeem txuas nrog daim di ncauj kub kub kub kub ua kom tiav kev tswj tuab tuab (ATC), tswj cov tuab tuab (ATC), tswj cov thickness kom tsis kam ua ntej ± 2-3%.

· Rede txiav cov cuab yeej: txiav tawm cov tuab ntaub ntawv pov tseg ntawm ob sab ntawm daim ntawv.

Herher warder: txais ib lub chaw / nto winding lossis Turret hom dual chaw nres tsheb yog qhov tseem ceeb los xyuas kom meej nro txog kev nruj me ntsis.

 

5. Ntug Khoom Siv Khoom Siv Hluav Taws Xob

Cov ntaub ntawv pov tseg tam sim ntawd tsoo rau hauv kev sib xyaw ua ke hauv online (xws li 10%-thiab rov qab siv dua tshiab, thiab siv tus nqi tsawg dua, txo tus nqi.

Hom Tshwj Xeeb: CPet Cov Kab Ntau Lawm

Cov kab ntau lawm rau cua sov - ionistant cpet cov ntawv (siv rau microwave / Cub cov tais) yuav tsum tau muaj cov khoom siv crystall.

· Txheej Txheem: Mr. Prod. luam tawm cov ntawv qhia pob tshab thiab tam sim ntawd dhau lawv los ntawm kev ua online cua sov crystallization cub. Daim ntawv yog rhuab rau cov crystallization kub ntau yam ntawm tus tsiaj (~ 160 {}} 18}} 18}} 18}} 18}} 18}} 18}} 18}} 18}} 18}} 18) Nws cov cua sov-resistant kub yuav tau nce siab rau ntau tshaj 220℃C.

· Cov kab no yog sib npaug los ntxiv tshooj crystallization nyob rau sab nraum qab kawg ntawm cov kab ntau lawm.

· Lub tshuab kom huv yog lub hauv paus siab: {- Cov kab ke zoo deshumidification thiab cov dej kom qhuav yuav tsum tau ua haujlwm rau cov khoom lag luam tsiaj.

· Qhov tseeb precision xav tau: Qhov yuav tsum tau ua rau cov khoom siv thickness, pob tshab gauge, thiab lwm yam.

Cov khoom siv ywj siab tam sim no: Cov High Yuav muab tso rau qhov zoo ntawm cov khoom siv raw (tshwj xeeb tshaj yog cov kev nyiam huv (piscosity ntawm cov chaw tsim khoom.

· Kev Noj Khoom: Cov txheej txheem ziab thiab cov txheej txheem kom qhuav yuav tsum muaj qhov kub thiab txias, ua rau muaj hluav taws xob tseem ceeb.

 

 

Tus tsiaj ntawv extrusion tshuab kab yog kev thev naus laus zis ua rau muaj kev sib tw ua kom zoo nkauj ntxiv, thiab cov tub ntxhais nyob hauv:

1. Qhov kawg qhuav: lub zog dehumidification thiab cov ziab khaub ncaws muaj zog yog lub hauv paus tsis meej los ua kom cov khoom lag luam zoo.

2. Precision extrusion: lub tso pa extruden, iav twj tso kua mis, thiab precision tuag ua ke xyuas kom cov yaj, thiab kev sib luag ntawm cov txiv ntseej.

3. Kev tswj hwm cov txheej txheem thiab kev tswj hwm: peb txoj kev sib tw tuab thiab kev ntsuas tshuab tuab thiab cov lus qhia tsis siv neeg (ATC) kom ua kom cov khoom siv tuab kawg ntawm cov khoom tuab.

Xaiv ib daim ntawv tsiaj extrusion tshuab kab yog tiag xaiv lub tshuab siv hluav taws xob siab uas tuaj yeem tswj qhov kub thiab txias, noo noo, noo noo, thiab nro.

 

Tsiaj yog cov khoom siv hygroscopic. Ntawm cov mob huab cua nws nqus cov av noo. Thaum lub sij hawm cov txheej txheem extrusion cov khoom siv noo noo yog raug rau cov tshuaj tiv thaiv hydrolysis ntawm cov khoom siv ntawm cov khoom siv tshuab hluav taws xob. Vim li no cov thev naus laus zis uas yuav tsum tau ua kom qhuav cov khoom siv nrog qib siab ntawm kev siv fais fab.

 

Siv Coinin tiam kawg ntawm ntxaib ntsia hlau EXTRUDERS, peb tuaj yeem pab zam kev ua kom qhuav thiab muab cov khoom siv tsiaj, ob qho tib si pelakes thiab flakes. Cov av noo cia -}} tawm los ntawm lub tshuab nqus hluav taws xob tau nruab rau ntawm cov extruder yog li zam lossis txo cov txheej txheem hydrolysis.

1. Nrog Twin ntsia hlau ntsia hlau daws, koj tuaj yeem tshem tawm cov pre-}} kev kaw lus thiab crystallization system. Qhov no yuav txuag yam tsawg 30% ntawm lub zog.

2. Cov ntawv kawg zoo yog txhim kho thaum muaj kev txiav txim siab tau zam dhau thaum lub sijhawm ua ntej ua ntej {1} {{2} lub sijhawm qhuav.

3. Nrog nyuj tshwj xeeb super nqus system thiab cov ntsia hlau tsim nyog, peb tuaj yeem tswj hwm IV poob hauv ib qho kev lees paub, ib txwm 0.03 nyob ntawm cov ntsiab lus ya raws.

4. Nrog Twin Ntsia Hlau, koj tuaj yeem siv tag nrho cov extruder muaj peev xwm. Thaum tib ntsia hlau extruder muaj ntau dua kev khiav nrawm, koj yuav plam lub zog ntau dua kom tau txais cov khoom zoo ib yam.
