Ntau tus neeg muas zaub los ntawm peb lub vev xaib rau xov tooj lus qhia txog qhov nrov ntawm cov hnab ntim khoom, ces hnub no DongLai woven hnab Xiaobian los piav qhia qhov nrov ntawm cov hnab ntim khoom.
Hom hnab woven
Woven hnab kuj hu ua snakeskin hnab. Nws yog ib hom yas, feem ntau yog siv rau ntim. Cov khoom siv raw yog feem ntau polyethylene, polypropylene thiab lwm yam khoom siv yas raw khoom. Ntawm no yog ib qho kev qhia luv luv rau hom woven hnab thiab siv.
Polyethylene yog cov khoom siv tseem ceeb ntawm kev tsim tawm txawv teb chaws, polypropylene yog cov khoom tseem ceeb ntawm domestic. Nws yog ib qho thermoplastic cob ua los ntawm polymerization ntawm ethylene. Hauv kev lag luam, nws kuj suav nrog copolymer ntawm ethylene nrog me me ntawm α-olefin. Polyethylene yog odorless, non-toxic, waxy, muaj qhov kub thiab txias tsis kam (tsawg kawg kev khiav hauj lwm kub txog -70 ~ -100 ℃), zoo tshuaj stability, feem ntau acid thiab alkali corrosion kuj (acid resistance, oxidation), insoluble nyob rau hauv dav cov kuab tshuaj nyob rau hauv chav tsev kub, tsis tshua muaj dej nqus, zoo heev hluav taws xob rwb thaiv tsev kev ua tau zoo; Txawm li cas los xij, polyethylene yog rhiab heev rau ib puag ncig kev ntxhov siab (tshuaj lom neeg thiab cov khoom siv hluav taws xob) thiab muaj kev tiv thaiv tsis zoo rau kev laus thaum tshav kub kub. Cov khoom ntawm polyethylene sib txawv los ntawm ntau yam mus rau ntau yam, feem ntau nyob ntawm tus qauv molecular thiab ntom. Cov txheej txheem ntau lawm tuaj yeem tso tawm qhov sib txawv (0.91-0.96g / cm3). Polyethylene tuaj yeem ua tiav tib txoj kev uas cov thermoplastic zoo tib yam yog molded (saib Plastic processing ). Siv dav hauv kev tsim cov yeeb yaj kiab, ntim khoom, cov kav dej, ib leeg xaim, xaim thiab cable, khoom siv txhua hnub, thiab lwm yam. Nws tuaj yeem siv los ua cov khoom siv hluav taws xob ntau zaus rau TV, radar, thiab lwm yam. Nrog rau kev lag luam petrochemical, cov khoom siv polyethylene tau tsim sai heev, suav txog li 1/4 ntawm tag nrho cov khoom yas. Xyoo 1983, lub ntiaj teb tag nrho cov peev txheej ntawm polyethylene yog 24.65 metric tons, thiab cov nroj tsuag nyob rau hauv kev tsim kho muaj peev xwm ntawm 3.16 metric tons.
Polypropylene (PP)
Ib qho thermoplastic cob ua los ntawm polymerization ntawm propylene. Muaj peb hom configurations, uas yog, tag nrho isotopic, atactic thiab indirect. Cov khoom lag luam feem ntau yog tsim los ntawm cov qauv isotopic. Polypropylene kuj suav nrog cov copolymer ntawm propylene thiab ib qho me me ntawm ethylene. Nws feem ntau yog translucent, tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom. Vim nws cov qauv kev cai, siab crystallinity, melting point mus txog 167 ℃, kub tsis kam. Nrog rau qhov ceev ntawm 0.90g / cm3, nws yog lub teeb tshaj plaws ntau yam yas. Corrosion kuj, tensile zog 30MPa, lub zog, rigidity thiab pob tshab yog zoo dua li polyethylene. Qhov tsis zoo yog qhov kub tsis zoo cuam tshuam tsis zoo, yooj yim rau kev laus, tab sis tuaj yeem hloov kho thiab ntxiv cov tshuaj antioxidant kom kov yeej.
Cov xim ntawm lub hnab woven yog dawb los yog tawm-dawb feem ntau, uas tsis yog-tshuaj lom thiab saj tsis qab, kev ua phem rau tib neeg lub cev yog feem ntau me me. Txawm hais tias ua los ntawm ntau hom tshuaj yas, tab sis muaj zog tiv thaiv ib puag ncig, rov ua dua lub zog;
Woven hnab yog siv dav, feem ntau yog siv rau ntim ntau yam khoom, thiab siv dav hauv kev lag luam;
Lub hnab yas woven nrog polypropylene resin yog cov khoom siv tseem ceeb, extrusion thiab ncab rau hauv xov tiaj, thiab tom qab ntawd woven rau hauv ib lub hnab.
Composite yas woven hnab nrog yas woven ntaub raws li lub hauv paus khoom, los ntawm cov ntws molding.
Siv los ntim cov hmoov los yog cov khoom siv granular thiab cov khoom siv tau yooj yim. Composite yas woven hnab muab faib ua ob nyob rau hauv ib lub hnab thiab peb nyob rau hauv ib lub hnab raws li cov khoom tseem ceeb muaj pes tsawg leeg.
Raws li txoj kev xaws, nws tuaj yeem muab faib rau hauv lub hnab xaws hauv qab, xaws sab hauv qab hnab, ntxig lub hnab thiab cov hnab ntim cov nplaum nplaum.
Nyob ntawm qhov dav dav ntawm lub hnab, nws tuaj yeem muab faib ua 450, 500, 550, 600, 650 thiab 700 mm. Tshwj xeeb specifications yuav tsum tau pom zoo los ntawm ob tog.
Saum toj no yog qhov nrov ntawm cov khoom me me rau txhua hom kev ua tiav ntawm lub hnab woven ntsig txog kev sib tham, los ntawm kev sib koom ntawm cov ntsiab lus, mus rau qhov nrov ntawm cov hnab ntim khoom muaj qee yam kev txawj ntse, yog tias koj xav mus tob rau hauv lub hnab ntawm cov ntaub ntawv kev lag luam, tuaj yeem tiv tauj tus neeg muag khoom hauv peb lub tuam txhab, lossis mus rau sab hnub tuaj thiab woven hnab ntawm qhov chaw tshawb nrhiav, kev sib txuas lus sib tham hauv daim ntawv no.
