los ntawm Pab Pawg Txhawb Nqa Sewport • Tsib Hlis 25, 2022
Polypropylene Npuag Yog Dab Tsi?
Cov ntaub polypropylene yog ib lo lus siv los piav txog cov khoom siv textile uas yog los ntawm cov thermoplastic polymer polypropylene. Hom yas no yog ib feem ntawm pawg polyolefin, thiab nws tsis yog polar thiab ib nrab crystalline. Tom qab polyethylene, polypropylene yog cov yas thib ob uas tsim ntau tshaj plaws hauv ntiaj teb, thiab nws feem ntau siv rau hauv kev ntim khoom, straws, thiab lwm yam khoom siv thiab kev lag luam dua li nws siv rau hauv kev tsim cov ntaub.
Hom yas no yog thawj zaug tsim los ntawm lub tuam txhab Asmeskas Phillips Petroleum hauv xyoo 1951. Cov kws tshuaj Robert Banks thiab J. Paul Hogan tau sim rho roj av los ntawm propylene, thiab lawv tau tsim polypropylene tsis tau xav txog. Txawm hais tias qhov kev sim no tau suav tias yog qhov tsis ua tiav, nws tau lees paub sai sai tias cov tshuaj tshiab no muaj peev xwm sib npaug nrog polyethylene hauv ntau daim ntawv thov.
Txawm li cas los xij, txog xyoo 1957, polypropylene tau ua los ua ib yam khoom uas tsim nyog rau kev tsim khoom ntau. Xyoo 1954, tus kws tshuaj Italian Giulio Natta thiab nws tus npoj yaig German tau ua tiav hauv kev tsim cov khoom no rau hauv ib qho isotactic polymer, thiab lub tuam txhab Italian Montecatini tau pib tsim cov khoom no rau kev lag luam thiab kev siv rau cov neeg siv khoom sai sai.
Polypropylene tau raug muag thawj zaug nrog lub npe "Moplen," thiab lub npe no tseem yog lub npe lag luam sau npe ntawm LyondellBasell corporation. Txawm li cas los xij, nws feem ntau pom cov tshuaj no hu ua polypropylene lossis "polypro" luv.

Raws li kev siv polypropylene tau nrov zuj zus hauv ntau tus neeg siv khoom thiab kev siv hauv kev lag luam, nws tau maj mam pom tias hom yas no kuj tau qhia txog lub peev xwm ua cov ntaub. Cov ntaub Polypropylene yog cov ntaub tsis yog woven, uas txhais tau tias nws yog ua los ntawm cov khoom siv ncaj qha yam tsis tas yuav tig ntawm kev weaving. Qhov txiaj ntsig tseem ceeb ntawm polypropylene ua cov ntaub yog nws cov peev xwm hloov pauv dej noo; cov ntaub no tsis tuaj yeem nqus cov dej noo, thiab hloov chaw, dej noo hla dhau cov ntaub polypropylene tag nrho.
Qhov cwj pwm no tso cai rau cov dej noo uas tawm thaum hnav cov khaub ncaws polypropylene kom qhuav sai dua li nws yuav nrog cov khaub ncaws uas khaws cov dej noo. Yog li ntawd, cov ntaub no nrov hauv cov ntaub uas hnav ze ntawm daim tawv nqaij. Txawm li cas los xij, polypro muaj feem yuav nqus thiab khaws cov ntxhiab tsw ntawm lub cev thaum nws siv rau cov khaub ncaws hauv qab, thiab nws kuj yaj ntawm qhov kub qis. Cov ntaub polypro yaj tuaj yeem ua rau kub hnyiab loj, thiab qhov teeb meem no kuj ua rau nws tsis tuaj yeem ntxuav cov ntaub no ntawm qhov kub siab.
Cov ntaub polypropylene yog ib qho ntawm cov fibers hluavtaws uas sib dua tshaj plaws, thiab nws tiv taus feem ntau cov kua qaub thiab alkalis heev. Tsis tas li ntawd, qhov thermal conductivity ntawm cov khoom no qis dua li ntawm feem ntau cov fibers hluavtaws, uas txhais tau tias nws zoo tagnrho rau hnav thaum huab cua txias.

Tsis tas li ntawd xwb, cov ntaub no tiv taus kev txhuam, thiab nws kuj tiv taus kab thiab lwm yam kab tsuag. Vim nws cov yam ntxwv thermoplastic zoo, nws yooj yim rau pwm yas polypro rau hauv ntau yam duab thiab cov duab, thiab nws tuaj yeem hloov kho dua tshiab los ntawm kev yaj. Cov yas no kuj tsis yooj yim rau kev tawg ntawm kev ntxhov siab.
Txawm li cas los xij, polypro nyuaj rau zas xim tom qab nws raug tsim tawm, thiab nws kuj nyuaj rau ua cov ntaub no rau hauv cov qauv sib txawv. Cov ntaub no yooj yim rau kev puas tsuaj los ntawm UV, thiab nws tsis lo rau latex lossis epoxies zoo. Ib yam li txhua lwm cov ntaub ua los ntawm cov khoom siv hluavtaws, cov ntaub polypropylene kuj muaj kev cuam tshuam tsis zoo rau ib puag ncig.
Cov Ntaub Polypropylene Ua Li Cas?
Ib yam li feem ntau hom yas, polypro yog ua los ntawm cov tshuaj uas tau los ntawm cov roj hydrocarbon xws li roj av. Ua ntej, cov monomer propylene yog rho tawm los ntawm cov roj nyoos hauv daim ntawv roj, thiab cov monomer no tom qab ntawd raug rau cov txheej txheem hu ua saw-growth polymerization los tsim cov polymer polypropylene.
Thaum muaj ntau cov propylene monomers sib txuas ua ke, cov khoom siv yas khov kho tau tsim. Yuav kom ua tau cov ntaub siv tau, cov polypropylene resin yuav tsum tau sib xyaw nrog ntau yam plasticizers, stabilizers, thiab fillers. Cov additives no tau nkag mus rau hauv molten polypro, thiab thaum tau txais cov khoom xav tau, cov yas no yuav raug tso cai kom txias rau hauv cov cib lossis pellets.
Cov pellets lossis cov cib no ces raug xa mus rau lub Hoobkas textile, thiab lawv tau rov yaj dua. Feem ntau, cov polypropylene no ces raug tsim ua cov ntawv, lossis nws yuav raug tso cai kom txias hauv cov pwm. Yog tias cov ntawv raug tsim, cov fibers nyias no ces raug txiav rau hauv cov duab xav tau thiab xaws lossis nplaum los tsim cov khaub ncaws lossis cov ntaub so ntswg. Ntau yam kev tsim khoom sib txawv siv los tsim cov polypropylene rau hauv cov khoom tsis yog khaub ncaws.
Cov Ntaub Polypropylene Siv Li Cas?
Cov ntaub Polypro feem ntau siv rau hauv cov khaub ncaws uas xav tau kev hloov pauv dej noo.
