Pab koj xaiv cov pwm ntawm PA66 thermal so strips

Txhua lub chaw tsim khoom thermal so xav muab PA66 thermal so strips nrog qhov loj me thiab zoo. Yog li cas peb tuaj yeem tsim PA66 thermal so strips nrog qhov ntau thiab tsawg? Pwm tso lub luag haujlwm tseem ceeb heev.  
Cov pwm txiav txim siab cov kab noj hniav, PA66 strip zoo thiab PA66 strip ntau thiab tsawg.   

Thaum koj xaiv pwm, thawj yam uas koj xav txog yuav tsum yog cov khoom pwm.
Tom qab xyoo ntawm kev sim thiab txhim kho, peb tau sim ntau yam ntaub ntawv thiab hardness ntawm pwm daim hlau, thiab thaum kawg tau sau cov ntsiab lus hauv qab no raws li kev siv tiag tiag thiab cov neeg siv khoom tawm tswv yim:
Yog hais tias cov khoom pwm yog mos heev, nws tsis yooj yim rau tawg thiab txiav nto muaj ib tug siab smoothness. Txawm li cas los xij, nws yog ib qho yooj yim rau hnav thiab tsim kua muag. Tom qab siv rau ib lub sij hawm ntawm lub sij hawm, lub strips tsim yuav tshaj qhov kam rau ua.
Yog hais tias cov khoom pwm yog ib qho nyuaj heev, nws yog ib qho yooj yim rau tawg nyob rau hauv kev sib piv. Qhov chaw txiav tsis zoo heev, tab sis nws yog hnav-resistant thiab muaj lub voj voog ntev siv tau.
Yog tias koj xav paub qhov zoo tshaj plaws hardness, thov hu rau peb pab neeg muag khoom.

Qhov thib ob yam uas cuam tshuam rau pwm zoo yog txoj kev txiav ntawm pwm.
Rau lwm lub tuam txhab, lawv nyiam siv lub tshuab hluav taws xob nruab nrab ceev (tseem hu ua WEDM-MS) los ua cov phaj txias. Cov khoom siv hlau electrode ntawm WEDM-MS yog molybdenum xaim, thiab nws tau rov ua dua, yog li cov hlau electrode tseem hnav thaum ua tiav, ua rau qhov tseeb machining nyob ib ncig ntawm 0.01-0.02mm. Qhov nto roughness ntawm Ra yog nyob ib ncig ntawm 1.0-1.7μm.
Kev txiav nto ntawm hom pwm no tsis du txaus, yog li muaj kev tawm tsam ntau thaum pib. Thiab qhov ntau lawm ceev yuav qeeb, nws txhais tau hais tias cov tawm los yog tsawg. Ua tib yam kom muaj nuj nqis ntawm thermal so strips yuav siv sij hawm ntev dua, uas invisibly nce nqi ntau lawm. Tsis tas li ntawd, lub strip nto nyob rau theem pib yuav yog qhov ntxhib heev.

Rau peb lub tuam txhab, peb siv lub tshuab hluav taws xob qis qis (tseem hu ua WEDM-LS) los ua cov phaj txias. Cov khoom siv hluav taws xob hlau ntawm WEDM-LS yog tooj liab hlau, thiab nws tsis rov siv dua, uas zoo heev txhim kho qhov tseeb machining kom yog 0.002-0.01mm. Qhov saum npoo roughness ntawm Ra yog nyob ib ncig ntawm 0.05-0.2μm. Nrog WEDM-LS, qhov chaw txiav yog du thiab tiaj tus, uas yog ze rau qib sib tsoo. Yog li nws yuav yooj yim dua rau cov neeg siv khoom los tsim cov strips nrog pwm ua tiav los ntawm WEDM-LS. Thiab cov strips tsim nyob rau hauv cov theem thaum ntxov yuav muaj ib tug zoo nkauj nto thiab ib tug siab yield.  

Qhov thib peb yam uas cuam tshuam rau pwm zoo thiab PA66 sawb ntau lawm yog tus tsim ntawm conical degree.
Yog hais tias lub conical degree ntawm txias phaj yog loj heev, ces lub siab ntawm pwm kab noj hniav ntawm lub sawb yuav tsawg dhau. Nws yuav ua rau cov strip lub ntom ntom ntom dhau tsawg, ua rau tsis kaj sawb nto.
Yog hais tias lub conical degree ntawm txias phaj yog me me heev, ces qhov kev tiv thaiv ntawm lub sawb thiab cov pwm kab noj hniav muaj zog heev, yog li ntawd tsis yog txhua txhua strips tuaj yeem tawm ntawm txhua kab noj hniav. Txawm hais tias strips raug tsim, lawv cov npoo thiab cov ces kaum yuav ua tsis tiav.  

Tsis tas li ntawd, pwm nrog cov duab sib txawv muaj ntau theem ntawm conical degree. Rau cov pwm nrog cov duab nyuaj, qhov conical degree ntawm qhov sib txawv kuj txawv.
Yuav ua li cas xaiv ib tug haum conical degree nyob ntawm ntau xyoo ntawm kev paub. Txhawm rau kom ua tiav qhov tsim nyog conical, kev hloov kho yuav tsum tau ua ob zaug lossis peb zaug raws li cov txiaj ntsig kev xeem.

Qhov kawg tab sis tsis tsawg kawg, kev tswj lub peev xwm ntawm qhov tseeb ntawm qhov loj kuj yog qhov tseem ceeb cuam tshuam rau pwm zoo.
Txhua tus neeg muab pwm tuaj yeem txiav txhua yam ntawm cov pwm. Tab sis nyob rau hauv peb lub qhov muag, txiav pwm tsis txhais hais tias kev vam meej. Peb tsuas yog xav txog cov pwm kom tsim nyog thaum tsim nyog PA66 strips raug tsim los ntawm cov pwm no. Muaj 4 yam cuam tshuam rau qhov ntau thiab tsawg strip:

1.Shrinkage ntawm raw khoom.
Peb lub Hoobkas tau ua kev tshawb fawb thiab kev tsim cov khoom siv raw los ntawm qhov pib, yog li peb muaj kev nkag siab qee yam ntawm shrinkage tus nqi ntawm raw cov ntaub ntawv nyob rau hauv txawv formulations. Thaum txiav cov pwm, qhov shrinkage ntawm cov khoom siv raw yuav tsum raug txiav txim siab.

2.Qhov kub ntawm cov dej txias.
Chav tsev kub yog txawv nyob rau lub caij ntuj no thiab lub caij ntuj sov, yog li cov dej kub. Yuav muaj qhov yuam kev raws caij nyoog nyob rau hauv qhov ntau thiab tsawg strip. Txhawm rau txo qhov yuam kev raws caij nyoog, peb xav kom siv lub ntsuas kub kom ntsuas cov dej kub ntawm 25 ± 5 ° C. Rau PA strips nrog cov duab tshwj xeeb lossis kev xav tau siab ntawm qhov ntau thiab tsawg yuav tsum tau tsim nyob rau hauv qhov chaw ua haujlwm kub tsis tu ncua.

3.Mould ntau lawm rau txoj kab txaij
Rau qee cov duab nyuaj, ua ntej peb yuav ua ib txheej ntawm kev sim pwm. Raws li cov txiaj ntsig kev xeem, peb tuaj yeem tshem tawm qhov kev sim pwm no, tom qab ntawd ua cov pwm tshiab. Qee lub sij hawm peb tseem yuav tau ua ob pawg ntawm kev sim pwm. Qhov no kuj txhais tau hais tias peb cov nqi tsim khoom yuav nce ntxiv txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
Hauv Suav teb, cov khoom lag luam pwm feem ntau tsuas yog lav 1-2 qhov loj me. Tab sis peb tuaj yeem lav qhov tseem ceeb tshaj plaws.

4. Pwm kuaj
Tom qab cov pwm tsim, peb yuav kuaj pwm. Thiab peb yuav muab cov ncauj lus qhia ntxaws ntxaws rau cov neeg siv khoom raws li peb lub tuam txhab cov qauv xa khoom siab. Tsuas yog thaum lub sawb qhov ntau thiab tsawg tsim nyog, peb xav tias cov pwm tsim nyog.

Thaum cov neeg muas zaub tshuaj xyuas pwm quotes, lawv feem ntau tsuas yog pom tus nqi pwm thiab tsis yog cov khoom uas ua rau pwm tus nqi.
Txawm li cas los xij, cov ntsiab lus no yog qhov yooj yim ntawm cov pwm tsim nyog. Yog li peb tsis tuaj yeem xaiv cov pwm tsuas yog raws li tus nqi pwm.
