Cov qauv thiab cov khoom siv ntawm cov cua sov hlau
Cov hlau cua sov yuav tsum tiv taus qhov nro, khoov, corrosion, noo noo, laus, thiab muaj kev rwb thaiv tsev zoo. Nws raug pom zoo kom siv ob lub qauv hauv qab no.
Cua sov hlau qauv
(1) Ntau- txheej txheej txheej txheem (Daim duab 17). Cov iav fiber ntau txheej 2 dais lub zog tensile (nws lub zog tensile feem ntau tshaj 15 kg), thiab nws lub zog yuav tsum haum rau lub caij nplooj ntoos hlav txaj. Cov yas txheej 1 muab rwb thaiv tsev, corrosion kuj, thiab noo noo tsis kam . 3 yog cov hlau tsis kam.
(2) Kauv twisted qauv (Daim duab 18). Cov polyester-coated kuj xaim 3 yog twisted ntawm lub iav fiber core hlau 2, thiab txheej txheej yog cov yas rwb thaiv tsev txheej 1. Txhawm rau txhim kho qhov yooj ntawm cov hlau tsis kam, ntau-strand kuj yuav tsum tau siv, tshwj xeeb tshaj yog thaum txoj kab uas hla ntawm cov hlau tsis kam yog ntau dua 0.14 hli.
Cov khoom siv insulating
Qee lub chaw tsim khoom siv polyvinyl chloride ua txheej txheej insulating. Piv nrog cov roj hmab, nws muaj qhov zoo xws li kev laus ua haujlwm, roj tsis kam, tshuaj lom neeg tsis kam, ya raws, thiab cov xim zoo. Qhov loj tshaj qhov tsis zoo ntawm kev siv polyvinyl chloride raws li cov khoom siv hluav taws xob rwb thaiv tsev yog tias nws qhov siab tshaj plaws ua haujlwm kub tsis tuaj yeem tshaj 105℃(nws ua mos ntawm 75-80 degree). Chlorinated roj hmab ethylene yog cov khoom siv yas nrog kev ua haujlwm zoo, thiab nws qhov siab tshaj plaws ua haujlwm kub kub tuaj yeem ncav cuag 150 degree. Chlorinated roj hmab ethylene muaj cov cua kub zoo heev, tiv thaiv kev laus, thiab tshuaj tiv thaiv corrosion, thiab cov khoom tsis deform hauv dej ntub.
Polytetrafluoroethylene (F4) yog cov yas zoo heev. Nws lub zog tensile yog 150-300 kg / cm². Nyob rau hauv qhov kub thiab txias, nws cov khoom siv kho tshuab zoo dua li cov yas dav dav, thiab nws lub neej qaug zog zoo ib yam li cov hlau. Tsis muaj kev quab yuam sab nraud, nws tseem tuaj yeem tswj qhov kev ruaj ntseg ntawm 250 degree. Nws qhov siab tshaj plaws kev khiav hauj lwm kub yog 260 degree, thiab nws kuj muaj hluav taws xob rwb thaiv tsev zoo heev. Nws tuaj yeem siv rau hauv ntau hom tshuaj corrosive media.
Polyethylene-propylene (FEP) yog ib qho copolymer ntawm tetrafluoroethylene thiab hexafluoropropylene, lub teeb heev, nrog cov khoom siv hluav taws xob zoo sib xws, thiab cov ntawv siv zoo sib xws.
Polyethylene (PE) muaj cov khoom siv hluav taws xob zoo heev, muaj lub ntiajteb txawj nqus tshwj xeeb, nqus dej tsawg, thiab tshuaj lom neeg ruaj khov thiab pwm ua haujlwm. Vim muaj cov txheej txheem polymerization sib txawv, polyethylene tau muab faib ua siab -siab, nruab nrab- siab, thiab qis- hom siab, thiab nws qhov siab tshaj plaws ua haujlwm kub yog 120 degree.
