5 cov khoom siv yas siv rau hlau thiab cable

Txawm hais tias cov hom ntawm hlauthiab xov hlaumuaj ntau yam, tab sis feem ntau ntawm cov qauv ntawm cov khoom zoo sib xws, cov ntaub ntawv raw siv yog qhov zoo ib yam, cov ntaub ntawv raw feem ntau suav nrog cov ntaub ntawv conductive, cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv tiv thaiv, cov ntaub ntawv tiv thaiv, cov ntaub ntawv sau, thiab lwm yam, thiab acTxoj hluaRaws li lawv cov khoom sib txawv, peb tuaj yeem muab faib ua ob pawg: cov khoom siv hlau, xws li tooj liab, txhuas, txhuas alloy, thiab cov khoom siv yas. Cov khoom siv PVC, PE, PP, thiab lwm yam, ua raws li 5 hom khoom siv yas uas feem ntau siv rau hauvhlauthiab xov hlau.

1. PVC, nws yog cov khoom siv yas feem ntau siv hauv cov hlau thiab Cable, PVC feem ntau yog siv rau cov hlau thiab cable rwb thaiv tsev thiab cov khoom tiv thaiv, qhov no yog vim PVC muaj ntau yam khoom tiv thaiv zoo uas tuaj yeem tiv thaiv cov hlau thiab cable sab hauv zoo, xws li PVC tsis yooj yim hlawv, laus tiv taus, roj tiv taus, tshuaj lom neeg corrosion tiv taus, cuam tshuam tiv taus, Cov yam ntxwv no ua rau nws muaj kev sib cais zoo thiab kev tiv thaiv, yog li cov ntaub ntawv rwb thaiv tsev dav dav ntawm hlau thiab cable feem ntau yog cov ntaub ntawv PVC.

2. NYOB RAU(Polyethylene), nws lub cev yam ntxwv yog dawb translucent waxy qauv, muaj kev ywj pheej zoo heev, tuaj yeem ncab mus rau qee qhov ntev, sib dua dej, tsis muaj tshuaj lom, tab sis piv rau PVC, polyethylene muaj tus cwj pwm yooj yim rau hlawv. Txawm tias tawm hauv hluav taws, nws yuav nyob hauv lub xeev hlawv, polyethylene kuj muaj ntau yam nthuav dav, suav nrog LDPE, MDPE, HDPE, LDPE yog ib qho ntawm qhov ceev qis tshaj plaws, hu ua low-pressure polyethylene, muaj kev ywj pheej zoo heev. MDPE yog nruab nrab density polyethylene, hu ua nruab nrab pressure polyethylene, kev ua tau zoo thiab high density polyethylene yeej zoo sib xws. HDPE kuj tseem hu ua high pressure polyethylene, nws cov kev ua tau zoo yog qhov zoo heev, tshwj xeeb tshaj yog kev tiv taus kub thiab lub zog kho tshuab tau raug kho kom zoo. Polyethylene muaj cov khoom rwb thaiv tsev hluav taws xob zoo heev thiab siv dav hauv kev rwb thaiv tsev ntawm cov xov hlau sib txuas lus.

3. EVA(ethylene - vinyl acetate copolymer), yog ib yam khoom siv thermoplastic zoo li roj hmab, nws qhov kev ua tau zoo thiab vinyl acetate (VA) cov ntsiab lus muaj kev sib raug zoo heev, qhov me dua cov ntsiab lus VA zoo li polyethylene, qhov siab dua cov ntsiab lus zoo li roj hmab yam ntxwv, EVA muaj qhov elasticity zoo thiab tsis kub tsis kam, tshuaj lom neeg tsis kam. Thaum sib xyaw nrog LDPE, Nws tuaj yeem txhim kho qhov teeb meem uas LDPE yooj yim tawg, thiab qhov cuam tshuam tsis kam, mos thiab tawv, thiab qhov sib txuas ntawm tus neeg coj thiab rwb thaiv tsev tuaj yeem sib koom tes zoo thiab muaj zog.

4. PP(Polypropylene), nws yog ib qho uas muaj qhov sib piv tsawg tshaj plaws ntawm cov yas siv tam sim no, lub zog siab, tsis kub, tsis laus zoo heev, ua ke nrog lub zog tawg siab, cov yam ntxwv nqus dej tsawg, PP cov khoom siv tuaj yeem tsim nyog rau txoj haujlwm ntawm cov ntaub ntawv rwb thaiv tsev zaus siab.

5. Polyester, hom khoom no yog tus cwj pwm los ntawm kev tsim kua muag siab, kev hnav tsis kam siab, siab elasticity thiab qis hysteresis, qhov siab tshaj plaws ntawm qhov kub thiab txias siv tau tuaj yeem ncav cuag 1500 degrees Celsius, uas yog ntau dua li lwm cov roj hmab thermoplastic, tab sis kuj muaj cov roj zoo heev, cov yam ntxwv tsis kam.

Boying yog ib tug kws tshaj lij xov hlau tus neeg muag khoom nrog pab pawg neeg paub txog, muab txhua yam ntawm xov hlau thiab txoj hlua hlauYog tias koj tab tom nrhiav cable tshwj xeeb, Boying muaj kev daws teeb meem tshwj xeeb rau koj.
