Yus li cas xaiv qhov tshuab ntaub ntawv uas muaj qhov ntau thiab tsis tuaj yeem rau qhov tshuab ntaub ntawv rau kev sib twj?

Kev tsim cov khoom tso cua thiab tso cua ntau yam no yog qhov kev tsim nyob rau hauv kev tsim kho thiab kev tsim lub tsev ntawm sijhawj no. Cov khoom no yog txaus los pab txhawj kom muaj kev siv cov cua thiab cua ntau yam zoo dua, txo kev tshuav cua thiab cua ntau yam, thiab pab tso cai rau kev nyab xeeb ntawm cov khoom aluminum. Rau cov neeg tsim khoom ntau yam thiab cov neeg xa mus nrhiav khoom, kev xaiv cov khoom siv tsim yog tsis yog qhov xaiv los xaiv xwb—nws yog qhov xaiv uas yuav tsum ua rau ntev. Nyob rau hauv qhov kev tsim no yog qhov single screw extruder. Kev xaiv qhov tseeb yog qhov txaus los pab txhawj kom muaj kev zoo tshwj xeeb, kev tsim ntau yam, thiab kev siv tau zoo. Qhov no yog qhov lus qhia uas qhia cov lus qhia tseem ceeb los ntawm qhov kev xaiv khoom ntawm cov neeg xa mus nrhiav khoom uas xav tau kev tsim khoom zoo thiab ntau yam, tias yuav tsum sib tham nrog cov neeg pab txhawb kom muaj kev pab txhawb ntau yam.

Paub txog qhov tseem ceeb ntawm qhov single screw extruder rau kev tsim cov khoom tso cua thiab tso cua ntau yam

Lub thawv tshuaj ntaus ntawv ib qhov yog lub thawv tshuaj ntaus ntawv uas siv tau zoo heev rau kev tsim cov cuab yeej thermal break strip. Lub hauv paus ntawv yog kom cov khoom sib xyaw (feem ntau yog polyamide (PA66) uas muaj cov ntawv qhia nyias thiab muaj cov ntawv nyias) los ua cov khoom ntaus, thiab ua rau nws muaj cov kab laug uas txaus siab thiab txaus siab rau hauv lub thawv tshuaj ntaus ntawv. Tsis zoo li lwm yam kev tsim, kev tsim cov thermal break strip polyamide uas tau txais lawm yog tseem ceeb rau lub thawv tshuaj ntaus ntawv ib qhov. Vim tias nws muaj kev pab zoo heev rau kev muab qhov pressure thiab qhov cua sov uas txaus siab thiab tuaj yeem suav tau rau qhov kev ua cov kab laug thiab kev sov, uas yog qhov tseem ceeb rau kev txais cov qhov meej thiab cov kev ua haujlwm.

Cov Luj Qhov Kev Tswj Hwm Tseem Ceeb Rau Kev Tsom Kev Ntau

Thaum peb xav txog lub thawv tshuaj ntaus ntawv ib qhov rau kev tsim thermal break strip ntau dua, cov luj qhov kev tswj hwm feem ntau yuav tsum tau txais kev xav txog. Cov luj qhov no yog qhov tseem ceeb rau kev txais cov khoom ntau, kev txaus siab, thiab kev ua haujlwm nrog cov khoom uas muaj kev tswj hwm zoo heev.

Cov ntawv ntaus ntawv thiab L/D Ratio

Daim ntawv ceeb ntawm lub khaub ncaws yog qhov tseem ceeb uas pab paub yuav muaj kev txhawb nqa li cas. Rau cov neeg xav tau ntau, cov khaub ncaws loj (piv txwv li 60mm, 90mm, lossis nyob rau hauv) yog qhov tseem ceeb. Qhov ntsiab lus uas sib npaug rau qhov no yog qhov kev sib raug zoo ntawm lub khaub ncaws thiab qhov dav (L/D). Qhov L/D loj (tshwj xeeb li 30:1 rau 40:1) pab ua kom muaj qhov chaw ua haujlwm loj dua. Qhov no pab kom cov ntawv ceeb tau thawb zoo dua, kom cov ntawv ceeb thiab cov ntawv ceeb ntawm lub khaub ncaws tau homogenized zoo dua, thiab pab kom cov ntawv ceeb tau txhawb nqa zoo dua, uas pab ua kom cov ntawv ceeb tau txhawb nqa zoo dua thiab muaj qhov zoo dua.

Kev txhawb nqa thiab qhov kev txhawb nqa ntawm lub khaub ncaws

Kev tsim cov ntawv ceeb ntau yuav tsum muaj lub system txhawb nqa zoo. Lub motor thiab qhov kev txhawb nqa yuav tsum muaj ntau heev rau kom ua haujlwm nrog cov ntawv ceeb uas muaj cov ntawv ceeb ntawm lub khaub ncaws thiab tsis tau tawg los sis, thiab tsis pab ua rau lub khaub ncaws tau tawg ntau. Lub system txhawb nqa zoo thiab muaj kev suav nrog zoo pab ua kom lub khaub ncaws tuaj yeem ua haujlwm raws li qhov tseem ceeb, uas yog qhov tseem ceeb rau kom muaj kev txhawb nqa zoo thiab qhov dav ntawm cov ntawv ceeb zoo.

Qhov nthuav dav hauv kev sau khaus

Qhov tshuab thiab qhov kawg yuav tsum muaj qhov chaw ua kom sov ntau yam, thiab yuav tsum muaj qhov chaw sov uas yuav tsum ua kom sov los ntawm lub cev. Qhov kev siv cov cuab yeej tshiab siv cov cuab yeej sov ceramic lossis cov cuab yeej sov aluminum uas tau muab sib sau rau cov cuab yeej ua kom cool nrog hliav lossis dej kom ua tau zoo heev rau kev saib xyuam txog qhov sov. Kev saib xyuam qhov sov raws li qhov tseem ceeb, tshwj xeeb yog rau qhov sov ±1°C, yog qhov tsis tuaj yeem txiav txim rau kev siv cov khoom polyamide-based, vim nws pab tshem tawm qhov sov li cas thiab pab tshem tawm qhov viscosity ntawm cov khoom ua kom txaus.

Qhov tseem ceeb ntawm kev siv cov khoom compound zoo heev

Kev ua haujlwm ntawm cov extruder single screw tshiab heev yuav tsum nyob rau hauv qhov zoo ntawm cov khoom uas nws siv. Ntawd yog qhov uas kev sib npaug ntawm cov neeg siv cov khoom thiab cov neeg muab cov khoom kom muaj txoj haujlwm tshwj xeeb yog qhov tseem ceeb heev. Cov granules polyamide raws uas tau muab tso cov fibers glass yog qhov tseem ceeb thiab yuav tsum muaj qhov zoo heev thiab tshwj xeeb.

Kev ua cov khoom zoo heev nrog kev siv cov screw ob

Thaum kawg no, kev kho kom txog rau qhov kev ua haujlwm ntawm qhov ntaub ntawv yuav tsum tau siv lub tshuab tso cua tib lub (single screw extruder), tab sis qhov kev ua haujlwm kab laj uas taug ntxiv rau qhov kev ua haujlwm no yog zoo tshaj plaws los siv lub tshuab tso cua ob lub (twin screw extruder). Lub tshuab tso cua ob lub uas muaj kev ua haujlwm tshwj xeeb yog zoo heev rau kev npaj thiab kev tso cua cov ntawv qias (glass fibers) raws li qhov tseem ceeb rau hauv qhov ntaub ntawv polymer. Cov ntawv qias uas sib txuas rau ib leeg (intermeshing screws) tsim qhov kev tso cua thiab kev npaj zoo heev uas tuaj yeem faib cov ntawv qias uas nyob rau hauv cov kab laj (fiber bundles) thiab tsim qhov kev tso cua tshwj xeeb rau hauv cov ntaub ntawv tshuab (pellet). Qhov no pab ua cov ntaub ntawv tshuab (compound granules) muaj kev ua haujlwm zoo tshaj plaws, muaj kev nyab xeeb rau qhov cua (thermal stability), thiab muaj kev ua haujlwm zoo rau kev tshuab tso cua (processability).
