Kev kuaj cov khoom siv polymer
Kev kuaj cov khoom siv polymer
Cov ntaub ntawv polymer yog dav siv. Peb yuav siv cov ntaub ntawv sib xws raws li cov kev xav tau tshwj xeeb, thiab cov yam ntxwv ntawm cov khoom siv yog ib qho tseem ceeb ntawm cov khoom siv. Cov khoom siv: yas, roj hmab, xim, nplaum, number case, thiab lwm yam.
Cov ntsiab lus kev pabcuam:
Cov ntaub ntawv polymer yog qhov tseem ceeb hauv lub neej niaj hnub no. Roj hmab, plastics, fibers, coatings, adhesives thiab lwm yam khoom sib xyaw, uas tuaj yeem raug ntaus nqi los ntawm kev tshawb nrhiav cov ntaub ntawv polymer.
Tuam Tshoj kuj tau tsim cov qauv kev ntsuas zoo ntawm cov ntaub ntawv polymer, thiab kev siv thiab tso tawm cov qauv kev ntsuas cuam tshuam tau zoo heev. Tau kawg, kev saib xyuas zoo thiab kev sim ua haujlwm los ntawm cov chaw sim thib peb los ua.
Tam sim no, kev ntsuam xyuas cov khoom siv polymer tau muaj kev koom tes hauv kev tshawb fawb, kev tsim khoom, kev muag khoom, kev yuav khoom, kev lag luam, kev tshuaj xyuas qhov tsis zoo thiab lwm yam haujlwm. Kev ua haujlwm ruaj khov thiab txhim khu kev qha yog qhov tseem ceeb los xyuas kom meej cov khoom siv ib txwm siv. Kev twv ua ntej thiab kev saib xyuas yog cov lus pom zoo. WSCT muab cov kev pabcuam kuaj txhua yam rau cov ntaub ntawv polymer.
1, Cov khoom pom zoo rau kev kuaj cov khoom siv polymer
Muaj ntau ntau hom polymers, thiab cov khoom ntsuas kev ua tau zoo ntawm cov ntaub ntawv polymer sib txawv yog txawv.
Siv cov txheej txheem polymer ua piv txwv
Lub cev lub cev peb xav kom kuaj nws qhov ntom ntom, xim, zoo li, hardness, acid tus nqi, cov ntsiab lus tshauv, stickiness, yooj, fineness thiab lwm yam ntsuas.
Rau kev siv niaj hnub ua haujlwm, peb pom zoo kom kuaj nws qhov adhesion, zais lub zog, sib tsoo tsis kam, cuam tshuam tsis kam, thiab lwm yam.
Cov ntaub ntawv fiber ntau tuaj yeem tsom mus rau kev tshawb pom ntawm lawv cov tshuaj fiber ntau muaj pes tsawg leeg, kev tshuaj xyuas ntau yam tshuaj, roj cov ntsiab lus, purity, noo noo regain, huab cua permeability, electrostatic zog, nplaim retardancy thiab lwm yam.
Zoo ib yam li cov khoom siv polymer xws li cov yas alloys thiab FRP cov khoom, nws raug nquahu kom kuaj xyuas cov khoom sib xyaw, tensile zog, tev lub zog, cov khoom muaj zog, thermal conductivity, combustion zog thiab lwm yam.
