Thaum ua tiav ntau yam kev tsim kho ua haujlwm, nws feem ntau tsim nyog los tsim cov dej noo-pov thawj, suab nrov-rwb thaiv tsev lossis txheej rwb thaiv tsev. Feem ntau, cov ntawv tshwj xeeb ua npuas polyethylene tau siv rau kev tsim cov chaw zoo li no. Hnub no peb yuav tham txog qhov khoom siv no yog dab tsi, txiav txim siab nws ntau yam thiab daim ntawv thov.

Peculiarities

Foamed polyethylene yog nyob rau hauv daim ntawv ntawm cov ntawv mos ntawm cov tuab tuab. Lawv yog cov duab plaub thiab muaj cov qauv zoo nkauj . Cov khoom siv no zoo heev thiab muag muag, feem ntau nws sov me ntsis rau qhov kov. Polyethylene ua npuas ncauj hauv cov ntawv yog tsim los ntawm extrusion lossis txhaj tshuaj molding ntawm cov npuas ua pawg nyob hauv qee qhov siab. Hauv qhov no, polyethylene ntawm qib sib txawv ntawm qhov ntom tuaj yeem siv tau. Cov khoom muaj cov cua sov qis, nws tau txiav txim siab muaj kev nyab xeeb rau tib neeg thiab lawv kev noj qab haus huv, vim tias freon tsis siv rau nws cov khoom. Thiab tseem ua npuas dej polyethylene khav theeb cov dej tsis zoo.

Cov khoom siv no zoo nkauj heev ua haujlwm nrog . Nws muaj peev xwm txo qis qhov muaj peev xwm tiv thaiv lwm cov txheej txheem siv, yog li nws feem ntau siv rau kev tiv thaiv ntxiv ntawm cov ntoo. Foamed polyethylene muaj qib siab hnav tsis kam thiab ua haujlwm ntev. Nws yog qhov ua tau tsis puas los ntawm cov nas me lossis kab.

Cov khoom muaj tus nqi qis, yog li nws yuav pheej yig rau yuav luag txhua tus neeg yuav khoom.

Saib

Foamed polyethylene ntawv yog ntawm ob peb yam tseem ceeb ntau yam

Unstitched . Qhov no yog qhov kev xaiv pheej yig tshaj. Rau nws cov khoom lag luam, siv extrusion, thaum lub molten polymer loj tau coj los ua lub hauv paus. Cov haujlwm no tau ntim nrog roj (feem ntau yog butane). Nyob rau tib lub sijhawm, nyob rau hauv tus txheej txheem ntawm kev nchuav rau hauv cov pwm, qhov sib xyaw ua ke los ntawm kev cuam tshuam ntawm huab cua hauv ntiaj teb, cov pa roj me me zoo li tawm mus rau saum npoo, hauv daim ntawv no lawv ua kom nrawm nrawm thiab tsim cov qauv ntawm tes. Feem ntau, cov thev naus laus zis no tso cai rau koj los tsim cov khoom siv nrog cov qauv pore loj.

Chemically stitched . Txog kev tsim khoom ntawm hom ntawv ua npuas dej polyethylene no, yuav luag tib lub thev naus laus zis tau siv zoo ib yam li yav dhau los. Tab sis tib lub sijhawm, kev kho tshwj xeeb nrog hydrogen peroxide yog siv ua txheej txheem ntxiv. Nws ua rau nws muaj peev xwm tshem tawm txhua qhov ua tsis tau ntawm cov khoom. Nyob rau tib lub sijhawm, lub hauv paus pib denser ntau dua, cov cell tau me dua.

Xaws los ntawm lub cev lossis hluav taws xob txhais tau tias . Hom polyethylene ua npuas ncauj no yog qhov kim tshaj plaws. Hauv qhov no, kev sib txuas sib txuas ntawm cov molecules ntawm cov polymer loj tshwm sim vim yog kev ntws ntawm cov hluav taws xob, uas tawm los ntawm hluav taws xob. Kev cuam tshuam hluav taws xob tso cai rau kev tsim cov ntoo khaub lig-txuas, uas ua rau muaj zog ntxiv dag zog rau lub lattice ntawm cov khoom. Thaum kawg ntawm kev tsim khoom, feem ntau ywj thiab muag muag nrog lub ntsej muag txawm tias tau txais, thaum nws tuaj yeem tiv taus qhov tseem ceeb. Polyethylene ua npuas ncauj, xaws ua txoj hauv kev no, rov qab nws cov duab qub sai dua tom qab deformation, thiab nws tseem ua tau zoo dua rau lwm cov ntaub ntawv piv rau hom yav dhau los.

Cov ntawv ua npuas dej polyethylene tuaj yeem sib txawv raws qhov loj me. Ua ntej tshaj plaws, thaum xaiv cov khoom siv, koj yuav tsum tau them sai sai rau qhov tuab ntawm daim ntawv. Raws li txoj cai, nws tuaj yeem sib txawv ntawm 20 txog 50 hli.

Qhov dav ntawm txhua daim ntawv tuaj yeem sib txawv . Rau cov qauv qauv, nws tuaj yeem yog 600-1200 hli, tab sis muaj cov qauv nrog lwm qhov txiaj ntsig. Qhov ntev ntawm cov khoom tuaj yeem ncav cuag kwv yees li 1500-3000 mm.

Cov ntawv thov

Foamed polyethylene tuaj yeem siv rau ntau thaj chaw ntawm kev tsim kho, tab sis feem ntau nws tau siv los tsim cov txheej txheem txhim khu kev ntseeg ntawm lub suab rwb thaiv tsev, raws li rwb thaiv tsev, tiv thaiv dej noo … Cov khoom tuaj yeem txuas rau hauv pem teb, qab nthab, phab ntsa npog . Yog tias koj xav txhim kho cov cuab yeej tiv thaiv ntawm lub hauv paus no, koj tuaj yeem ntxiv nws nrog cov ntawv ci txhuas, uas yog glued rau ib sab ntawm daim ntawv xwb. Cov hauv paus zoo li no feem ntau tau muab tso rau ntawm cov pob zeb ua haujlwm - hauv qhov no, lawv ua raws li cov cua sov tshwj xeeb, tiv thaiv hluav taws xob infrared rau sab hauv. Ua li no, cov cua sov yuav tau txuag ntau ntau.

Hom polyethylene hauv cov ntawv no qee zaum siv los tsim cov ntim khoom . Ntau yam tsis hloov pauv tau zoo dua rau lawv, thaum hom no tsis pom zoo rau kev teeb tsa ua haujlwm. Cov ntawv polyethylene ua npuas ncauj yuav yog qhov kev xaiv zoo tshaj plaws rau kev tsim txheej txheej sib khi ntxiv rau lub qhov rooj thiab ob-glazed qhov rais. Lawv kuj tseem siv rau hauv qhov xwm txheej uas nws yuav tsum tau nqa tawm kev thauj mus los kom raug ntawm lwm cov ntaub ntawv.

Cov ntawv txheeb tau siv dav hauv kev siv tshuab . Feem ntau, cov khoom siv no yog siv cov insulator txhim khu kev qha rau ntau yam khoom siv tub yees thiab tshuab cua txias. Qee lub sij hawm xws li polyethylene tau siv hauv kev tsim cov kab xev ob tog, ntau daim kab xev sib txuas, cov khoom siv tus kheej tsim los nqus kev co. Hauv cov tsheb thauj khoom hnyav, nrog kev pab los ntawm cov khoom siv no, rwb thaiv tsev feem ntau tsim nyob hauv lub nra.

Cov ntawv ua npuas kuj tseem siv hauv kev kho mob . Muaj lawv tau pom daim ntawv thov dav vim lawv cov kev ywj pheej thiab yoog raws: cov khoom yooj yim rov ua lawv cov duab txawm tias tom qab kev hloov pauv hnyav. Cov hauv paus nrog cov yam ntxwv no yuav yog qhov kev xaiv zoo tshaj plaws rau kev tsim ntau yam corsets, khau insoles.

Niaj hnub no hauv khw muag khoom, cov neeg siv khoom tuaj yeem pom ntau yam ntaub pua plag me me ua los ntawm cov khoom siv no. Lawv tso cai rau koj pw hauv av, thaum tso siab tiv thaiv tib neeg lub cev los ntawm kev kub taub hau.
