PVC daim kab xev yog cov khoom siv nyiaj txiag uas tau siv dav hauv kev rwb thaiv tsev ntawm ntau yam ntaub ntawv. Vim nws txoj kev yooj yim thiab tus nqi pheej yig, nws tau pom daim ntawv thov dav hauv ntau qhov chaw. Thawj daim kab xev tau tsim rov qab rau xyoo 1946 hauv Asmeskas, tom qab ntawd nws tau hloov kho tas li thiab hloov pauv.
Ntse
PVC insulating daim kab xev ua kom nruj ntawm qhov sib txuas ntawm cov khoom sib txawv thaum ua haujlwm engineering, kho lossis hluav taws xob ua haujlwm thiab kev tiv thaiv los ntawm ntau yam xav tau. Kev siv cov khoom siv no yog qhov muaj txiaj ntsig zoo thaum tsim nyog los thaiv cov khoom nqa tam sim no, cov xov hlau liab qab, uas ua haujlwm tiv thaiv tib neeg yog tias lawv yuam kev lawm.
Key Features
Ntawm PVC daim kab xev muaj cov yam ntxwv hauv qab no: qhov dav nce mus txog 13 txog 20 hli nrog lub thickness tsawg kawg yog 0.13 hli. Ntxiv mus, lub thicker daim kab xev, lub siab dua yuav nws insulating zog. Cov yam ntxwv tseem ceeb ntawm daim kab xev hluav taws xob suav nrog:
- High breakdown voltage. Ntau lub tuam txhab qhia meej cov khoom siv hluav taws xob siab ntawm cov kab xev, yog li lawv tuaj yeem tiv taus qhov hluav taws xob siab.
- Guaranteed zoo ntawm hluav taws xob rwb thaiv tsev yog muab nrog rwb thaiv tsev nyob rau hauv ob-peb txheej.
- Vim muaj qee yam kev tiv thaiv tshav kub, PVC daim kab xev tuaj yeem siv rau hauv qhov kub thiab txias, mus txog qhov kawg.
- zoo adhesion. Nws yog muab los ntawm kev xav ua ke ntawm cov thickness tsis nrog hom nplaum txheej.
- Lub zog thiab tawg voltage. Kev ua tau zoo heev tso cai rau daim kab xev siv hauv kev ua haujlwm hluav taws xob ntawm txhua qhov nyuaj.
- Tensile zog. Lawv pab ua kom lub peev xwm elastic ntawm daim kab xev.
- Cov khoom tua hluav taws. Daim kab xev feem ntau yog siv los ua cov xov hluav taws xob, yog li nws yog ib qho tseem ceeb uas tsis muaj kev pheej hmoo ntawm hluav taws xob lossis hluav taws xob poob.
Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.
PVC-raws li rwb thaiv tsev daim kab xev muaj zoo sealing thiab dielectric zog thiab zoo stretchability. Tab sis ntawm qhov kub thiab txias, daim kab xev yuav yaj, yog li nws yuav tsis ua haujlwm. Thaum xaiv cov khoom siv insulating no, ib qho yuav tsum tau ua los ntawm cov ntsuas hluav taws xob, cov av noo, qhov kub thiab txias ntawm cov khoom ntawm cov rwb thaiv tsev thiab qhov kub thiab txias.
Kev sib xyaw thiab nta
PVC insulating daim kab xev yog ua los ntawm semi-vinyl chloride thiab tuaj hauv daim ntawv yob ntawm daim kab xev, qhov dav ntawm 14-19 hli. Vim nws cov khoom ua tau zoo heev, cov khoom siv yog siv los ua ke, fastening, kho, ntim thiab ntau lwm yam haujlwm. Nws yog ib qho tseem ceeb hais tias rau daim kab xev nrog acrylic nplaum txheej, adhesion yuav siab dua thaum lub sij hawm ua hauj lwm, thaum cov roj hmab txheej qhia nws cov khoom nplaum yuav luag tam sim ntawd. Rau ntaCov khoom siv insulating no yog tawg-pov thawj thiab nplaim-retardant, tab sis cov ntaub nplaum yuav tso cov tshuaj lom thaum hlawv.
Cov khoom hluav taws xob hluav taws xob ua kom lub peev xwm ntawm daim kab xev tiv taus txog li 5000 volts ntawm qhov hluav taws xob, uas yog txaus rau kev ua haujlwm hauv lub neej txhua hnub thiab tom haujlwm. PVC daim kab xev (GOST 16214-86) yog dav siv thaum tsim nyog los tsim rwb thaiv tsev rau cov xov hlau, cables, kav. Txhawm rau kom cov khoom ua haujlwm tau zoo, nws yuav tsum raug siv kom raug: koj yuav tsum tau cua nws los ntawm nyias kawg mus rau tuab. Yuav tsum ceev faj tshwj xeeb kom insulate cov xov hlau liab qab, thiab tsis tas yuav rub daim kab xev ntau dhau.
Txoj kev nplaum nplaum
Insulating daim kab xev tau pom dav daim ntawv thov nyob rau hauv ntau yam teb. Self-adhesive PVC daim kab xev muaj ib tug nplaum txheej uas tiv thaiv txheej txheej ntawm cov kav dej los ntawm corrosion, ua raws li ib tug insulating thiab tiv thaiv txheej. Daim kab xev yuav tsum tsis txhob muaj qhov tsis xws luag, kua muag, qhov khoob ntawm cov nplaum nplaum, kom lub sealing ua tau zoo thiab ua tau zoo raws li qhov ua tau. Cov nplaum muaj pes tsawg leeg feem ntau muaj cov roj hmab puag, qhov twg cov yas kuj tseem ntxiv. Nws txoj hauj lwm yog los muab kev tiv thaiv rau sab nraud cuam tshuam, nrog rau cov av noo thiab kub txo.
Daim kab xev zoo yuav tsum muaj qhov du, ncab zoo thiab ruaj khov rau ntawm lub hauv paus. Cov nplaum nplaum ntxiv kom ntseeg tau tias daim kab xev yuav raug kho ntawm txhua qhov chaw.
Nws thov nyob qhov twg?
PVC daim kab xevdav siv:
- Thaum ua haujlwm hluav taws xob. Hauv qhov no, cov khoom siv ntau yam no insulates cov xov hlau, cables, thaum kho kho, cables raug cim thiab pob.
- Thaum ua haujlwm hauv tsev rau ntau lub hom phiaj, thaum kho cov khoom siv hauv chav ua noj, cov cuab yeej thiab lwm yam khoom me me yuav tsum tau ua.
- rau kev kho tsheb me me.
- Thaum ntim khoom. PVC raws li daim kab xev nplaum yog siv dav hauv phau ntawv lossis tsis siv neeg kaw lub thawv nruab nrab hnyav.
- Thaum kho cov nkoj raws li roj hmab, PVC reinforcing daim kab xev yog dav siv.
Kev saib xyuas tshwj xeeb tsim nyog siv PVC daim kab xev rau cov kav dej.
txheej txheem nta
Kev tiv thaiv cov raj xa dej tau raug saib xyuas zoo, vim tias kev nyab xeeb thiab kev ntseeg tau ntawm kev ua haujlwm ntawm tag nrho cov kab ke nyob ntawm nws. Cov hlau nteg hauv av yog tas li nyob rau hauv kev cuam tshuam ntawm ib puag ncig tsis zoo, yog li ntawd, yuav tsum muaj kev tiv thaiv kev ruaj ntseg ntawm kab. Rau qhov no, PVC yeeb nkab rwb thaiv tsev daim kab xev feem ntau siv. Ua tsaug rau nws cov khoom tshwj xeeb, sab nrauv yog tiv thaiv corrosion, nws cov rwb thaiv tsev thiab kev tiv thaiv txhim khu kev qha yog nqa tawm. Tab sis rau qhov no nws yog ib qho tseem ceeb uas daim kab xev yog thov kom raug. Qhov no yog ua raws li hauv qab no: cov yeeb nkab yog them nrog cov ntaub nplaum, thiab kev ua haujlwm yog nqa tawm hauv ib lub kauv. Qhov no yuav zam cov tsos ntawm wrinkles los yog distortions. Kev rwb thaiv tsev yeeb nkab nrog PVC daim kab xev yog qhov zoo rau ntau yam:
- Cov khoom siv tiv taus heevKev nqus dej noo, yog li ua tiav waterproofing yog guaranteed.
- Cov khoom ntawm daim kab xev tiv taus cov kab mob thiab corrosion.
- Vim cov nplaum nplaum nplaum muab lub zog siab.
Kev tiv thaiv hluav taws xob
PVC daim kab xev yog ntau yam thiab tuaj yeem siv rau ntau lub hom phiaj. Qhov kub ntawm daim ntawv thov yog los ntawm 0 txog 90 degrees, thiab kev ua haujlwm yog ua tau ob qho tib si sab hauv tsev thiab sab nraum zoov. Cov khoom yog nthuav tawm nyob rau hauv ntau yam xim. Nws yuav tsum nco ntsoov tias daim kab xev insulating yuav tsum tsis muaj ntxhiab tsw, txwv tsis pub nws qhia tias tsis zoo.
Cia thiab cov lus pom zoo
Cov kab xev rwb thaiv tsev yuav tsum muab cia rau hauv cov tsev khaws khoom kaw, thiab koj yuav tsum tau saib xyuas qhov kub thiab txias - ntawm +5 txog +36 degrees ntawm qhov txheeb ze av noo ntawm 80%. Tsis txhob siv PVC daim kab xev ua ke nrog cov kuab tshuaj organic, tshuaj lom neeg, cov kua dej flammable thiab aggressive media. Cov lus pom zoo siv yog raws li hauv qab no:
- Qhov kub yuav tsum nyob nruab nrab ntawm 20-40 degrees.
- PVC daim kab xev tsis tuaj yeem siv rau cov txheej txheem silicone lossis cov polymers uas muaj fluorine. Deteriorating nto yuav tsum tau kho nrog primers.
- Insulating daim kab xev yog siv rau qhov chaw npaj, uas yuav kom qhuav kom huv si thiab tsis muaj kab mob.
Yog tias lub ntim, kev thauj mus los thiab kev khaws cia yog raug, daim kab xev hluav taws xob tuaj yeem khaws cia txog 10 xyoo txij li hnub tim.production.
