Tsim Kev xav rau Waterproof Junction Boxes

Tam sim no, cov khoom lag luam tsis muaj dej tsis sib haum feem ntau yog siv rau hauv ib puag ncig hnyav xws li chaw tsim khoom thiab qhib- huab cua ib puag ncig. Thaum xav txog cov khoom ua tau zoo, yam xws li kev cuam tshuam tsis zoo, lub zog zoo li qub, kev ua haujlwm rwb thaiv tsev, tsis yog - toxicity, aging resistance, corrosion resistance, thiab nplaim retardancy ntawm cov ntaub ntawv yuav tsum tau muab rau hauv tus account. (Tsis yog-cov khoom muaj kuab lom tau txais kev saib xyuas thoob plaws, feem ntau vim tias cov thawv ntim dej tsis sib haum tsis tso cov pa phem thaum hlawv hluav taws. Feem ntau cov neeg tuag thaum hluav taws kub hnyiab yog vim nqus cov pa roj ntau ntau.

Kev tsim qauv: Lub zog tag nrho, kev zoo nkauj, kev ua kom yooj yim, kev yooj yim ntawm kev teeb tsa, thiab rov ua dua ntawm lub thawv dej tsis sib haum yuav tsum raug txiav txim siab. Tam sim no, cov tuam txhab thoob ntiaj teb tseem ceeb tsim cov thawv dej tsis muaj dej tsis muaj hlau fittings, ua kom yooj yim rau cov txheej txheem rov ua dua. Txawm li cas los xij, feem ntau cov tuam txhab tsim khoom siv hauv tsev siv cov khoom sib txawv nrog cov tsis muaj zog tiv thaiv warping. Lawv feem ntau siv tooj dag ntxig rau hauv cov mounting sockets kom nce lub zog ntawm lub zog, uas ua rau lub sijhawm thiab nqi ntawm cov khoom siv rov ua dua tshiab. Kev siv cov khoom siv ua haujlwm siab - los ntawm cov tuam txhab muaj koob npe tuaj yeem daws qhov teeb meem no.

Phab ntsa Thickness: Thaum tsim cov khoom, tag nrho cov nqi yuav tsum tau txiav txim siab, thiab cov phab ntsa tuab yuav tsum tau txo kom tsawg li ntau tau thaum ua tau raws li cov khoom muaj kev cuam tshuam thiab warping kuj yuav tsum tau. Thoob ntiaj teb, cov thawv ntim dej tsis muaj dej...) Hauv kev tsim, phab ntsa tuab ntawm cov ntaub ntawv feem ntau yog nruab nrab ntawm [tus nqi ploj lawm] thiab [tus nqi ploj lawm]; iav fiber ntau-polyester ntxiv yog feem ntau ntawm [tus nqi ploj] thiab [tus nqi ploj lawm]; thiab tuag- nrum txhuas feem ntau yog [tus nqi ploj lawm]. Cov khoom siv phab ntsa tuab yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm feem ntau cov khoom thiab cov khoom siv thaum tsim.

Kev xaiv ntawm cov khoom siv lub nplhaib sib khi: Rau cov khoom siv dej tsis sib haum, feem ntau siv cov khoom siv lub nplhaib sib khi muaj xws li [tus nqi ploj lawm]. Thaum xaiv cov nplhaib sib khi, qhov kub thiab txias, lub zog tensile, elongation, hardness, ntom, compressibility, thiab tshuaj tiv thaiv yuav tsum tau txiav txim siab.
