Cov teeb meem txog qhov loj ntawm cov polyamide thermal break strips yog dab tsi thiab yuav tsws kom tau li cas?

Txhawm rau ib tug khaub ncaws tsis sib txig tshaj tawv uas muaj kev paub txog kev kho tshuaj nrog kev xam pom tag 2006, peb paub tias nyob rau hauv cov khaub ncaws tsis sib txig tshaj tawv polyamide, vim li cas khaub ncaws tshaj tawv tsawg kuj tuaj yeem pab cuam tshuaj siab tshaj tawv. Cov khaub ncaws tshaj tawv tsis zoo tsis yog tsuav tsom kho kom tsis pub rooj mov thiab rooj zaum los ntawm kev lag luam, tab sis kuj tseem nce ntau nqi lag lag rau lawv. Thaum peb muab kev pab txhua yam—xam nrog kev tsim kho raw material, kev them nyiaj rau chav siv, thiab kev pab txheej txheem—peb pab cov neeg siv khoom nrhiav thiab txaus kom nyob ntawm cov teeb meem tshaj tawv uas feem ntau, kom meej tias txhua lub khaub ncaws tsis sib txig tshaj tawv tau txais qhov tshaj tawv.

Yuam li cas tshaj tawv zoo muaj txuj ci

Qhov sib txig ntawm tshaj tawv zoo thiab kev ua haujlwm tsis sib txig tshaj tawv

Polyamide thermal break strips yog qhov tseemceeb tshaj plaws hauv kev sib tshuam ntawm lub voj voog aluminum. Ib daim tsis zoo (xws li cov kab ntsug thiab txheej tsis muaj kev sib xws) yuav tshwm sim cov chaw tawg nyob saum npoo ntawm lub voj voog aluminum, ua rau kub rov qab mus los thiab txo dej nkhaus ib tug laug lossis ntau dua. Piv txwv li, ib daim muaj kab nrog hauv npoo yuav tso siab hauv av, uas sib txuas kub ntau dua li polyamide meej. Hauv cheeb laub no, qhov no txhais tau hais tias tso ntau tshij rau kev sib poob kub; hauv cheeb laub kub, siv ntau zog rau kev sov. Cov thermal break strip zoo tshaj plaws tsis yog ib qho khoom—nws yog ib qho pheej hmong rau kev ruaj khov nyob hauv kev siv zog xaum deb.

Caij sem kev tsis zoo rau cov khaiv kho

Qhov chaw tsim kho tsev uas siv cov rooj zaum kub txias tsau tsis zoo yuav tsum nyob zej pom vim qhov no. Cov rooj zaum kub txias tsau tsis zoo feem ntau yuav break thaum sau, ua rau yuav tsum sau dua thiab yuav tsum nrhiav lub sijhawm tshiab. Txawm tias sau lawm los yog, nws feem ntau yuav txias deb ntev—tom qab 2-3 xyoo, yuav muaj qhov ntxig ntxag, ua rau qhov chaw tsim kho tsev yuav tsum txhawj xeeb rau cov kev pabcuam thiab kho rooj tsev tshiab. Yog tias peb yog ib qhov chaw pabcuam nyob ib qho, peb paub tias kom tsis txhob muaj teeb meem zoo li cas yuav txaus ci ntau dua li tom qab. Peb lub kev daws teeb meem yog tshuam mus rau sab ntawm tej teeb meem, tsis yog ib txwm kev daws teeb meem xwb.

Cov teeb meem hnyem siab tshaj plaws ntawm cov rooj zaum kub txias tsau Polyamide thiab lawv cov teeb meem

Kev sib txawv hauv qhov ntsiag

Qhov chaw tshuab tso siab yuav tsum tau muaj qhov loj me (thick 1.5-3mm, dav 10-30mm) kom raug rau lub profile aluminum. Qhov tsis raug ntawm qhov loj me—xws li qhov thick tsis zoo lossis txoj laug uas muaj tog—tuaj yeem pom tib neeg ua ib ob hom teeb meem. Thaum tob, tshuab extrusion tsis raug: siv tshuab screw ob (uas yog tshuab tsuas yog rau granulation, tsis yog rau production strip) tuaj yeem ua rau tsis nyob siab, vim tias screw ob tsis tuaj yeem sau ceev rau kev nqus tshuab rau kev tsim form strip. Ob, kev tsim die los yog kev xaiv tshuab rolling tsis raug—yog hais tias qhov chaw flow ntawm extrusion die tsis raug, qhov strip yuav thick dua nyob qhov twg; yog hais tias tshuab rolling tsis parallel, qhov edge yuav raug uas muaj tog.

Txoj Caij Tsawg Kev Nyob

Qhov chaw tshuab khib nyiab muaj qhov tsis zoo yuav tshav ntau thaum sau lub sijhawm los yog siv. Qhov teeb meem no muaj qee yam tej meej: ob tus neeg xaib zoo. Yog hais tias tsis muaj kev faus zoo, tsis faus cov kab roj fiberglass raug rau hauv, ces qhov chaw khib nyiab yuav muaj qhov ceeb toom. Tus kib ntawm qhov chaw khib nyiab tsis raug—yog tias khib nyiab muaj qhov ntxuav dua, nws yuav ua rau saum npoo molecular tsis zoo, thiab yog tias chaws ntau dua, yuav ua rau kab roj fiberglass hlo, thim li ua rau qhov chaw khib nyiab tsis tuaj nqus siab dua. Piv txwv li, qhov chaw khib nyiab uas muaj kev faus tsis zoo kab roj fiberglass yuav muaj qhov nqus siab tsawg kawg li 50MPa, uas tsawg dua 80MPa uas yog standard rau kev siv qhov chaw khib nyiab.

Yuav ua li tiv thaiv qhov teeb meem zoo li cas nrog peb lub tswvyim

Cov duab plaub zoo los ntawm cov twj tso cua tshuab

Qhov txheej xwm zoo ntawm qhov thermal break strips yog qhov granules zoo—and peb lub twin screw extruders thim qhov no. Lub twin screws ua haujlwm nrawm nrawm rau sib tso fiberglass rov tav mus rau hauv polyamide raws, tsim qhov chaw sib sau. Qhov sib piv no tshem tseg cov kab ntsug lossis siab, thiab pab ntxuav qhov ceev—peb lub granules muaj qhov fiber dispersion rate tshaj 95%, nyob ib leeg txog qhov strip tas mus muaj qhov ceev zoo (tensile strength ≥82MPa). Peb kuj nthuav dej los txhawv dej txog ≤0.1% ua vor extrusion, kom tso tseg qhov ntau yam. Yog ib qhov khoom feem ntawm peb lub one stop service, peb xa khoom granules no mus rau pej xeem, kom tso tseg qhov risk ntawm cov khoom third party uas tsis zoo.

Single Screw Extruders rau Stable Strip Production

Xaiv: tsuas yog extruders nrog rov tshaj yam chawg chiv rau kev tsim polyamide thermal break strips. Peb cov custom single screw extruders muaj kev coj qhov speed (2-5m/min) thiab kev saib xyuas teperature nrog ntau qhov chaw (230-250°C), thim siab tias kev extrusion yuav nyob ntzab. Cov extruders txawm ntxiv nrog peb cov dies uas tau zoo tshaj plaws—muaj qhov flow channels sib npaug thiab die lips uas tuaj yeem raug kho—thim tsim cov strips uas muaj qhov ntev thiab meej nyob rau hauv ±0.05mm. Peb kuj xaiv ib extruder rau ntxiv nrog ib rolling machine precision (muaj rolls poob tshaub thiab servo guides) kom kho cov ceev lees meej, thim siab tias qhov flatness thiab qhov ntev ntawm strip yuav dhau standards. Qhov kev sib cuag ntawm cov khoom no yuav tshem tawm qhov teeb meem hauv qhov ntev uas tau los ntawm kev xaiv khoom tsis raug lossis kev tsis sib xws.

Kev pab txhawb teknik ib chav thiab kev saib xyuas lub zog

Kev pab txhawb nqa tsev ib chaw ntawm peb tsis yog tsuas yog xaiv khoom thiab tshuab—peb muab kev pab txhawb nqa kom tso tseg kev xwm txheej. Peb xa cov neeg kho tshuab mus rau qhov chaw nyob ntawm neeg siv khoom los tsim kho tshuab: kho tshuab nqus, txiav txim tshuab rov los thiab qhuab sib luag cov neeg ua hauj lwm txog kev hloov pauv (xws li kev nruj ntawm tshuab nqus raws li tus nqi ntawm dej nyob hauv av). Peb kuj muab cov tshuab soj ntsuam xwm txheej: cov tshuab soj ntsuam laser rau kev soj ntsuam saum npoo, cov tshuab soj ntsuam zog rau kev soj ntsuam zog thiab cov tshuab soj ntsuam dej rau kev soj ntsuam dej hauv khoom nqus. Rau kev tsim kho tshuab nyob ib si, peb ua kev soj ntsuam thaum kawg—yog tias ib tug neeg siv khoom pom tias muaj qhov tsis zoo hauv saum npoo, peb pab nrhiav qhov ceev (xws li khoom nqus muaj dej), thiab peb muab kev daws teeb meem (xws li kev ntxig tshuab tshem dej). Kev pab txhawb no txhua yam kom paub tseeb tias xwm txheej zoo.

Rau cov khaub ncaws uas tsim kho mob tshuab kho, nyob ntawm kev ceev faib ces muab tso rau koj tus cwj pwm thiab txiav txim siab tias koj cov khoom siv zoo. Peb muaj ob lub sij hneev granulation, ib leeg sij hneev extrusion, mashines kho tshuab ntau thiab kev pab txhawb lag luam ib li cas los daws tej teeb meem no. Muaj 17 xyoo nyob hauv cheeb tsheb, peb paub yuav ua li cas los tsim kho cov duab ntawv polyamide thermal break strips zoo li cas—thiab peb xa qhov paub no mus rau koj cov neeg siv khoom los ntawm txhua qhov chaw hauv kev pab txhawb.
