5 hom yas raw khoom rau hlau thiab cable

Txawm tias hom ntawmhlauthiabkabmuaj ntau haiv neeg, tab sis feem ntau ntawm cov qauv ntawm cov khoom zoo sib xws, cov khoom siv raw siv yog tib yam, cov khoom siv raw muaj xws li cov khoom siv hluav taws xob, cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv tiv thaiv, cov ntaub thaiv npog, cov ntaub ntawv sau, thiab lwm yam, thiab raws li lawv qhov sib txawv. Cov khoom tuaj yeem muab faib ua ob pawg, cov khoom siv hlau, xws li tooj liab aluminium, aluminium alloy, thiab yas raw khoom. Feem ntau PVC, PE, PP, thiab lwm yam, ua raws li 5 hom yas raw khoom siv hauvhlauthiabkab.

1. PVC, itis feem ntau siv yas raw cov ntaub ntawv nyob rau hauv hlau thiab cable, PVC feem ntau yog siv rau hlau thiab cable rwb thaiv tsev thiab cov ntaub ntawv tiv thaiv, qhov no yog vim PVC muaj ntau yam zoo tiv thaiv khoom uas yuav ua tau ib tug zoo tiv thaiv ntawm hlau thiab cable sab hauv, xws li PVC tsis yooj yim rau hlawv, kev laus ua haujlwm, roj tsis kam, tshuaj tiv thaiv corrosion, cuam tshuam tsis kam, 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 cov hlau thiab cable feem ntau yog cov ntaub ntawv PVC.

2. ON(Polyethylene), nws cov yam ntxwv ntawm lub cev dawb translucent waxy qauv, muaj qhov yooj yim heev, tuaj yeem ncav cuag qhov ntev, sib dua li dej, tsis muaj tshuaj lom, tab sis piv rau PVC, polyethylene muaj cov yam ntxwv ntawm kev yooj yim hlawv. Txawm tias tawm hauv qhov hluav taws kub, nws yuav nyob twj ywm kub hnyiab, polyethylene kuj muaj ntau yam nthuav dav, xws li LDPE, MDPE, HDPE, LDPE yog ib qho qis qis, hu ua low-pressure polyethylene, muaj qhov yooj yim heev. MDPE yog nruab nrab ntom polyethylene, hu ua nruab nrab siab polyethylene, kev ua tau zoo thiab siab ntom polyethylene yog qhov zoo sib xws. HDPE tseem hu ua high-pressure polyethylene, nws cov kev ua tau zoo tshaj plaws, tshwj xeeb tshaj yog thaum tshav kub kub tsis kam thiab lub zog txhua yam yog ob qho tib si tau zoo. Polyethylene muaj cov khoom siv hluav taws xob zoo heev thiab yog siv dav hauv kev rwb thaiv tsev ntawm kev sib txuas lus cables.

3. EVA(ethylene - vinyl acetate copolymer), yog cov roj hmab zoo li cov thermoplastic, nws cov kev ua tau zoo thiab vinyl acetate (VA) cov ntsiab lus muaj kev sib raug zoo, qhov me me ntawm VA cov ntsiab lus zoo li polyethylene, cov ntsiab lus siab dua yog cov yam ntxwv roj hmab, EVA muaj 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, softness thiab hardness, thiab adhesion ntawm tus neeg xyuas pib thiab rwb thaiv tsev tuaj yeem ua haujlwm zoo thiab ntxiv dag zog.

4. PP (Polypropylene), nws yog ib qho uas muaj qhov tsawg tshaj plaws ntawm cov khoom siv niaj hnub no, muaj zog txhua yam, tsis muaj qhov kub thiab txias tsis kam, kev laus ua haujlwm zoo heev, ua ke nrog lub zog tawg siab, tsis tshua muaj dej nqus cov yam ntxwv, PP khoom tuaj yeem muaj peev xwm rau txoj haujlwm siab. zaus rwb thaiv tsev cov ntaub ntawv.

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