Hom thiab siv cov hnab woven
Hom:
Woven Hnab, Tseem hu ua cov nab hau tawv nqaij. Nws yog hom ntawm cov yas tsuas yog siv rau kev ntim khoom. Nws cov ntaub ntawv nyoos feem ntau ntau yam cov tshuaj siv cov tshuaj yas xws li polyethylene thiab polypropylene.
Cov khoom siv raw rau txawv teb chaws yog polyethylene (PE), thaum lub ntsiab kev tsim khoom yog polypropylene (pp), uas yog ib lub thermoplastic resin tau los ntawm polymerization ntawm ethylene. Hauv kev lag luam, nws tseem muaj ethylene thiab me me ntawm α-copolymers ntawm Olfins. Polyethylene tsis muaj ntxhiab, tsis muaj tshuaj lom, hnov zoo li cov tshuaj yaig uas muaj qhov tsawg kawg nkaus (tsis txhob siv cov pa hluav taws xob) Tab sis polyethylene yog rhiab heev rau kev ntxhov siab ib puag ncig (tshuaj lom neeg thiab cov neeg siv tshuab) thiab muaj kev kub ntxhov tsis zoo. Cov khoom ntawm polyethylene sib txawv los ntawm ntau yam rau ntau yam, feem ntau yog nyob ntawm cov qauv molecular thiab ntom ntom. Cov txheej txheem sib txawv cov txheej txheem tuaj yeem tawm los cov khoom nrog cov qauv sib txawv (0.91 ~ 0.96g / cm3). Polyethylene tuaj yeem ua tiav siv dav dav thermoplastic molding cov txheej txheem (saib yas). Nws muaj ntau yam ntawm kev siv, tsuas yog siv rau kev tsim cov yeeb yaj kiab nyias, cov xaim hluav taws xob, cov xaim hluav taws xob, thiab siv tau ntau yam txog 1/4 ntawm tag nrho cov khoom siv yas. Xyoo 1983, tag nrho cov peev txheej ntau lawm ntawm polyethylene hauv lub ntiaj teb yog 24.65mt, thiab lub peev xwm ntawm lub peev xwm tsim kho yog 3.16mt.
Tus thermoplastic resin tau los ntawm polymerization ntawm propylene. Muaj peb qho kev teeb tsa: ototactic, random, thiab syndotactic, nrog hootactic raws li lub ntsiab tivthaiv hauv cov khoom lag luam. Polypropylene kuj suav nrog Copolymers ntawm propylene thiab ib qho me me ntawm ethylene. Feem ntau ib semi pob tshab thiab tsis muaj kob, tsw ntxhiab thiab tsis muaj tshuaj lom. Vim nws cov qauv ib txwm muaj thiab qib siab ntawm crystallization, lub suab me me yog qhov siab li 167 ℃, thiab nws yog cua sov. Cov khoom tuaj yeem raug tshuaj tua kab mob, uas yog nws qhov kom zoo dua. Lub qhov ceev yog 0.90G / CM3, ua rau nws lub teeb pom kev zoo nkauj yas. Corrosion tsis kam, tensile muaj zog ntawm 30mpa, thiab lub zog zoo, thiab pob tshab dua li polyethylene. Qhov tsis zoo yog qhov tsis zoo-kub cuam tshuam tsis kam thiab kev laus, tab sis nws tuaj yeem kov yeej los ntawm kev hloov kho thiab kev sib ntxiv ntawm kev tiv thaiv kab mob antioxidies.
Cov xim ntawm cov hnab Woven feem ntau yog dawb lossis grey dawb, tsis muaj tshuaj lom thiab tsw tau muaj kev phom sij rau tib neeg kev noj qab haus huv. Txawm hais tias lawv tau ua los ntawm ntau yam tshuaj plastics, lawv muaj kev tiv thaiv kev tiv thaiv thiab kev rov ua dua tshiab;
