HDPE Daim Ntawv Txheej Txheem
High - qhov ceev polyethylene (HDPE) yog engineering yas ua los ntawm high- ntom polyethylene cob. Nws muaj zoo heev corrosion, puas yog cuam tshuam, cuam tshuam tsis kam, thiab ib puag ncig kev nyuaj siab tawg tsis kam. Nws yog dav siv nyob rau hauv cov tshuaj, machinery, ua zaub mov, thiab tshuaj lag luam. Cov haujlwm tsim nyog thiab txoj kev teeb tsa yog qhov tseem ceeb los xyuas kom meej tag nrho cov kev ua haujlwm.
Ua ntej - Kev Ua Haujlwm Npaj Npaj
1. Kev kuaj ib puag ncig
• Ua kom muaj thaj chaw ua haujlwm yog huv si, qhuav, thiab cov tshuaj sib xyaw lossis cov tshuaj xeb kom tsis txhob khawb lossis paug daim ntawv HDPE saum npoo.
• Cov kev ua haujlwm kub pom zoo yog nruab nrab ntawm -50℃thiab 80 degree. Kev khiav hauj lwm kub nyob sab nraum cov kab no tej zaum yuav cuam tshuam cov khoom siv khoom.
2. Tool Npaj
• Cov cuab yeej pom muaj xws li pom tes pom, cov ntaub ntawv, cov kuab tshuaj nplaum (xws li cov dej cawv oreopropyl, thiab goggles.
• Yog tias vuam yuav tsum tau siv phom lossis cov cua kub vuam lossis cov neeg teb xov xwm vuam yuav tsum muaj, thiab tus neeg teb xov tooj yuav tsum tau kawm.
3. Daim Ntawv Kuaj Xyuas
Txheeb xyuas daim ntawv HDPE specifications (tuab, qhov ntev) kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua. Tshawb xyuas cov nplaim rau qhov tsis xws li cov kab nrib pleb thiab npuas.
Txiav thiab Ua Qauv
1. Txiav
• Kev tuav txhais tes: Siv tes pom lossis nuv cutter los txiav raws txoj kab kev cim ntawm qeeb, txawm tias nrawm, ua kom nrawm, ua kom nrawm, kom nruj.
• Siv tshuab tej tshuab: ib lub vas sab pom lossis hluav taws xob pom yog pom zoo. Qhov nrawm yuav tsum tsis txhob siab dhau (pom zoo tsawg dua lossis sib npaug rau 3000 rpm). Siv tus tungsten carbide pom hniav kom txo burrs. Tom qab txiav, cov npoo yuav raug txiav nrog cov ntaub ntawv.
2. Drilling thiab xuas nrig ntaus
• Siv qhov siab - Ceev hlau loj laum me ntsis ntawm kev ceev thiab rpm thiab deformation tshwm sim los ntawm melting. Lub qhov taub ntawm cov cheeb tsam yuav tsum yog qhov loj dua li cov ntsia liaj qhov rooj uas los pab cov teeb tsa cov khoom siv tsis sib haum.
3. Chamfering thiab Polishing
• Chamfer cov npoo nrog cov xuab zeb lossis cov ntaub ntawv (45℃tau pom zoo) kom tiv thaiv kev ntxhov siab thiab kev raug mob rau tus neeg teb xov tooj.
Txhim kho thiab kho
1. Ncaj Ncaj Haum
• Ntxuav cov chaw tiv tauj (siv isopropyl cawv kom tshem tawm roj). Muab cov ntawv qhia HDPE tiaj tus thiab ib ncig. Xyuas kom muaj kev nruj haum siv cov tshuab ua kom siab (piv txwv li cov kev sib tw) lossis siab hnyav.
• Yog yuav tsum tau sib txuas lus, siv cov kuab tshuaj -} Raws cov nplaum (piv txwv li - cov nplaum tshwj xeeb). Siv rau cov chaw huv, qhuav thawj qhov chaw ua ntej. Cia cov kuab tshuaj kom yaj rau 5-10 feeb ua ntej nias. Tswj hwm kom tsawg kawg 24 teev.
2. Bolt kho
• Tom qab -} drilling, siv nylon lossis stainless hlau bolts nrog roj hmab ntxhua khaub ncaws kom txo kev ntxhov siab. Zawm lub bolts tusyees kom tsis txhob muaj kev cuam tshuam hauv zos.
3. Vuam nyem (haum rau loj- cheeb tsam spricing)
• Cov huab cua kub kub: kho cov chaw vuam taws kub rau 200-250 degree. Thaum tshav kub kub lub vuam pas nrig thiab cov khoom siv hauv paus ua ke kom txog thaum molten, tom qab ntawd nias lawv ua ke. Cov lus pom zoo Weld dav yog loj dua los yog sib npaug rau 3 hli.
• Extrusion vuam: Siv tus Extruder sau cov sib koom tes nrog cov khoom siv PE. Hom no yog tsim nyog rau cov ntawv thov uas xav tau lub zog siab dua.
Fandling ceev faj
1. Kev ceev faj kev nyab xeeb
• Hnav cov hnab looj tes thiab cov phuam qhwv caj dab thaum ua haujlwm kom tiv thaiv kev txaws ntawm kev txiav cov khoom siv lossis cov khoom siv molten. Zam kev ua kom tawv nqaij ntev nrog kev sib chrationed HDPE (yuav ua rau muaj kev ntxub me me).
2. Zam kev raug mob
• Zam tsis txhob rub lub sijhawm thauj mus los tiv thaiv cov khawb npoo. Khaws kom deb ntawm qhov kub thiab cov tshuaj corrosive (xws li muaj zog acids thiab alkalis).
3. Txij Nkawm
• Ntxuav sab saum npoo av tsis tu ncua (siv ib qho chaw so nruab nrab) kom tsis txhob khawb ntawm cov khoom tawv. Yog tias raug rau UV teeb rau ncua sijhawm, thov cov txheej txheem tiv thaiv kom pom zoo.
Kev daws teeb meem cov teeb meem nquag
• Txiav cov burrs: xuab zeb nrog cov khau khiab zoo lossis rov - luas txiav.
• Kev Ua Haujlwm Tsis Ua Haujlwm: txheeb xyuas qhov chaw huv si, thov kua nplaum, thiab txuas ntxiv lub sijhawm nias lub sijhawm.
• Weld Cracking: Txheeb xyuas qhov ntsuas kub kom tsim nyog thiab nrawm, thiab ua haujlwm yog tias tsim nyog.
Proper HDPE sheet handling not only improves construction efficiency but also ensures long-term stable operation. Cov neeg ua haujlwm yuav tsum ua raws li cov txheej txheem thiab kho cov ntsiab lus raws li cov ntawv thov tshwj xeeb los muab tag nrho cov txiaj ntsig ntawm HDPE cov laug cam.
