Ton hnab ntim cov duab
Kev ntim khoom tsim nyog muaj txiaj ntsig zoo rau kev khaws cia, kev thauj mus los, thiab tso saib, nrog rau kev muag khoom. Yog li ntawd, cov duab yog ib qho tseem ceeb hauv kev ntim khoom.
Tuj lub hnab ntim xim
Xim yog cov khoom lag luam muaj txiaj ntsig tshaj plaws ntawm kev ntim khoom. Cov xim ua ke nrog cov khoom zoo tshaj plaws tuaj yeem tsis tsuas yog ntxiv dag zog rau cov yam ntxwv ntawm cov khoom lag luam, tab sis kuj tseem muaj kev txaus siab rau cov neeg siv khoom.
Ua ntej, cia peb tham txog cov khoom hluav taws xob ntawm polyethylene resin. Polyethylene resin yog cov khoom siv tsis-polar nrog cov khoom siv hluav taws xob zoo, tsis muaj dielectric poob, thiab lub zog dielectric siab. Yog li ntawd, polyethylene tuaj yeem siv ua FM rwb thaiv tsev. Corona-resistant plastics thiab high-voltage rwb thaiv tsev cov ntaub ntawv. Thib ob, polypropylene muaj cov khoom siv dav dav, tsis tshua muaj zog tensile, tsis zoo creep tsis kam, thiab muaj kev cuam tshuam zoo. Yog li ntawd, nws yog feem ntau cuam tshuam los ntawm qhov ntom ntom, crystallinity, thiab txheeb ze molecular mass. Polyethylene yog cov khoom siv raw rau kev tsim cov hnab ntim khoom. Tom qab ua tiav kev sib sib zog nqus, raws li cov ntsuas no nce, cov khoom siv kho tshuab ntawm polyethylene tau txhim kho.
Hauv kev ua cov hnab loj, nws yog qhov tsim nyog los tswj qhov kub thiab txias, cov khoom siv viscosity, thiab lawv cov yam ntxwv cuam tshuam. Qhov kub thiab txias yog ib qho tseem ceeb uas cuam tshuam rau kev ua cov hnab loj. Kev kub ntau dhau yuav tsis tsuas yog cuam tshuam rau kev siv zog thiab lub zog, ua rau cov nqi ua haujlwm nce ntxiv tab sis tseem cuam tshuam rau qhov zoo ntawm lub hnab ntim cov txheej txheem. Qhov cuam tshuam ntawm kev txhaj tshuaj kub ntawm lub hnab tuj ntawm cov txheej txheem molding, seb qhov kub ntawm cov yas yaj yog qhov tsim nyog, tuaj yeem pom los ntawm kev kub siab inching. Cov khoom siv kub zoo yuav tsum ua kom cov khoom txau muaj zog, tsis muaj npuas, tsis muaj curl, ci, thiab tsis tu ncua.
