Taw qhia:

PET daim ntawv pob tshab ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub, tshwj xeeb hauv kev ntim khoom noj. Txawm li cas los xij, cov txheej txheem tsim khoom thiab cov teeb meem feem ntau cuam tshuam nrog cov ntawv PET yog qhov tseem ceeb uas cuam tshuam rau ob qho tib si zoo thiab kev tsim khoom. Tsab ntawv xov xwm no yuav piav qhia txog cov txheej txheem tsim khoom thiab cov teeb meem ntawm PET pob tshab nplooj ntawv, muab cov kev daws teeb meem los pab cov neeg nyeem nkag siab zoo dua thiab daws cov teeb meem hauv kev tsim cov ntaub ntawv PET.

I. Txhais thiab Siv PET

PET pob tshab ntawv yog cov ntawv yas pob tshab ua los ntawm Polyethylene Terephthalate (PET) resin. PET resin yog cov khoom siv yas uas paub txog nws qhov kub thiab txias tsis kam, tshuaj lom neeg, thiab lub zog zoo heev. Cov ntawv pob tshab no nthuav tawm cov pob tshab siab thiab cov khoom siv lub cev zoo dua, ua rau lawv siv dav hauv ntau daim ntawv thov. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam ntim, PET pob tshab nplooj ntawv yog nyiam rau lawv cov pob tshab zoo, durability, thiab moldability. Hauv kev lag luam xws li zaub mov, dej haus, thiab tshuaj, PET nplooj ntawv feem ntau yog siv los ua pob tshab ntim ntim xws li lub raj mis thiab jars. Lawv cov pob tshab tso cai rau nthuav tawm cov khoom lag luam thaum muab kev sib khi zoo thiab kev tiv thaiv corrosion kom zoo khaws cov khoom zoo. Tsis tas li ntawd, PET cov ntawv pob tshab pom cov ntawv thov hauv lwm qhov chaw xws li cov khoom siv hluav taws xob thiab cov ntaub ntawv luam tawm, muab cov ntim khoom zoo thiab cov duab pom rau ntau yam khoom.

II. Kev tsim khoom ntawm PET

A. Raw Khoom Npaj
Kev tsim cov nplooj ntawv PET pib nrog kev npaj cov khoom siv raw. Qhov no suav nrog kev xaiv cov khoom tsim nyog PET kom ntseeg tau tias cov khoom muaj qhov pom tseeb zoo. Tsis tas li ntawd, additives xws li toughening agents thiab stabilizers yog tsim kom raug raws li cov khoom yuav tsum tau txhim khu kev ua tau zoo thiab stability.

B. Cov txheej txheem tsim khoom
Cov txheej txheem tsim cov ntawv PET feem ntau suav nrog kev sib tw, extrusion, thiab molding. Thaum pib, PET resin yog rhuab mus rau lub xeev molten thiab extruded rau hauv xov siv ib tug extruder. Tom qab ntawd, cov extruded PET threads yog txuas ntxiv los ntawm lub tshuab los ua cov ntawv nyias. Thaum kawg, cov nplooj ntawv PET extruded yog txias thiab molded siv cov pwm kom tau raws li qhov xav tau cov duab thiab qhov loj ntawm cov khoom kawg.

C. Tom qab ua tiav
Tom qab kev tsim khoom, PET pob tshab nplooj ntawv tau dhau los ua haujlwm tom qab txhawm rau txhim kho lawv cov kev ua tau zoo thiab pom kev zoo. Qhov no suav nrog kev ua kom txias, ncab, thiab txiav cov kauj ruam. Thaum pib, cov ntawv PET molded yog txias kom khov lawv cov duab. Tom qab ntawd, nyob ntawm qhov xav tau, cov ntawv txias txias tau ncab los txhim kho lawv lub cev. Thaum kawg, cov nplooj ntawv PET stretched raug txiav mus rau qhov ntev uas xav tau kom tau txais cov khoom kawg.

III. Tej teeb meem thiab kev daws teeb meem

A. Qhov teeb meem zoo

• 1. Npuas:  Cov npuas yog ib qho teeb meem zoo ntawm qhov chaw thaum lub sij hawm tsim PET pob tshab ntawv. Txhawm rau txo cov npuas tsim, kho cov txheej txheem extrusion tsis xws li txo qis extrusion kub thiab nce extrusion siab tuaj yeem txhim kho cov khoom ntws thiab tiv thaiv kev tsim npuas.
• 2. Loj:  Burrs cuam tshuam rau cov tsos thiab qhov zoo ntawm daim ntawv thiab yog li kev ntsuas yuav tsum tau coj los txo lawv cov tiam. Optimizing tus tuag tsim thiab ua rau lub sij hawm txias tuaj yeem txo cov burrs thiab txhim kho qhov smoothness ntawm cov khoom.
• 3. Dej pov thawj:  Thaum lub sij hawm extrusion txheej txheem, kev huv huv ntawm cov khoom siv extruder thiab ib puag ncig yog qhov tseem ceeb kom tsis txhob muaj cov dej pos huab. Khaws cov khoom siv extruder kom huv si thiab ua kom ib puag ncig huv si thaum lub sij hawm extrusion txheej txheem tuaj yeem txo qhov tshwm sim ntawm cov dej pos huab.

B. Teeb meem kev ua tau zoo ntawm lub cev

• 1. Lub zog tsis txaus:  Yog tias cov nplooj ntawv PET tsis muaj zog, nce qhov sib piv thaum lub sijhawm ncab tuaj yeem txhim kho daim ntawv muaj zog. Tsis tas li ntawd, kho cov ntaub ntawv tsim tawm thiab ntxiv cov tshuaj ntxiv tuaj yeem txhim kho lub zog.
• 2. Tsis zoo Abrasion Resistance:  Xaiv cov PET resin nrog kev puas tsuaj zoo dua los yog txheej txheej nrog cov txheej txheem puas-resistant zoo txhim kho daim ntawv puas. Ntxiv cov additives tsim nyog thaum lub sij hawm tsim khoom txhim kho daim ntawv abrasion kuj.
• 3. Tsis zoo Compression Resistance:  Optimizing extrusion txheej txheem tsis xws li nce molding siab tuaj yeem txhim kho compression tsis kam ntawm PET pob tshab nplooj ntawv. Rau cov khoom uas xav tau lub zog siab, xav txog kev siv cov khoom siv dag zog los yog cov khoom ua kom cov thickness txhim kho compression kuj.

C. Kev hloov ntawm cov txheej txheem Parameters

• 1. Kev tswj qhov kub thiab txias:  Kev tswj xyuas qhov kub thiab txias thaum lub sij hawm PET daim ntawv yog qhov tseem ceeb los xyuas kom meej cov khoom zoo. Los ntawm kev kho cov khoom siv cua sov thiab cua txias thiab ua kom zoo dua qhov kub thiab txias ntawm extruders, cov teeb meem tshwm sim los ntawm qhov kub siab dhau los yog qis qis tuaj yeem zam tau zoo.
• 2. Kev hloov siab: Kho qhov ntsuas siab ntawm extruders raws li tus yam ntxwv ntawm PET resin thiab cov khoom yuav tsum tau ua kom zoo dua cov txheej txheem ntau lawm, txhim kho cov khoom zoo thiab ruaj khov.
• 3. Ceev Optimization:  Tswj extrusion ceev yog qhov tseem ceeb rau kev ua kom cov khoom zoo thiab kev ua haujlwm ntau lawm. Los ntawm kev kho cov kev khiav hauj lwm ceev ntawm extruders kom tsim nyog, cov khoom qhov ntev thiab nto zoo tuaj yeem ua tau raws li qhov yuav tsum tau ua thaum txhim kho ntau lawm efficiency.

IV. Daim ntawv thov teb ntawm PET

Cov ntawv PET muaj kev cia siab ntau hauv kev lag luam ntim khoom, tshwj xeeb tshaj yog hauv cov khoom noj, dej haus, thiab tshuaj. Nrog rau cov neeg siv khoom xav tau ntau ntxiv rau cov khoom zoo thiab cov tsos, pob tshab PET ntim ntim yuav dhau los ua qhov tseem ceeb. Pob tshab ntim tsis tsuas yog nthuav tawm cov tsos thiab zoo ntawm cov khoom tab sis kuj txhim kho lawv cov kev muag khoom.

Hauv daim teb no,thermoforming tshuab ua lub luag haujlwm tseem ceeb. Thermoforming thev naus laus zis heats PET nplooj ntawv mus rau qhov kub thiab txias thiab tom qab ntawd pwm lawv mus rau hauv ntau yam duab ntawm pob tshab ntim ntim siv pwm.
