Cov hom ntim ntau tshaj plaws yog tsim los ntawm polyethylene zaj duab xis. Nrov T-shirt hnab thiab cov khoom siv rau cov khoom ntim khoom yog tsim los ntawm nws. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm kev yooj yim, lub tes tsho lub hnab yog qhov kev xaiv zoo tshaj plaws. Nws qhov zoo muaj xws li muaj peev xwm siv cov khoom ntawm qhov ntev sib txawv. Ntawd yog, nyob rau hauv qee txoj kev, tus neeg siv nws tus kheej tuaj yeem sib txawv ntawm kev ntim khoom. Tib lub sijhawm, lub tes tsho polyethylene khaws tag nrho cov txiaj ntsig ntawm lub hnab classic, uas suav nrog lub zog, yooj yim ntawm kev tuav thiab nruj.

lub tes tsho polyethylene siv qhov twg?

zaj movie yog lub hauv paus rau kev tsim cov hnab ntxiv. Yog li ntawd, nws tuaj yeem hu ua universal. Lub tes tsho tuaj yeem ua raws li cov khoom siv hauv kev tsim kho kev lag luam, muab kev lag luam catering, nrog rau hauv tsev. Raws li txoj cai, lub tes tsho polyethylene rau ntim yog siv rau qhov uas nws yuav tsum ua haujlwm nrog ntau cov khoom lossis cov khoom. Piv txwv li, rau cov khoom ntim khoom loj. Qhov tsis muaj cov seams thiab perforations tso cai rau koj los npaj cov kab ntim tsis siv neeg uas tsis tas yuav muaj kev koom tes ntawm cov neeg ua haujlwm.

Cov zaj duab xis yog siv los ntawm lub tes tsho thiab hauv cov chaw tshwj xeeb. Yog li, muaj polyethylene, Ameslikas tsim los siv rau hauv kev xav tau hluav taws xob. Nrog kev pab los ntawm xws li ib pob, koj tuaj yeem cais cov khoom siv thiab cov khoom siv, tiv thaiv lawv los ntawm kev ya raws. Lub tes tsho polyethylene rau cov yub kuj muaj ntau, uas yuav tsum tau nce ntxiv raws li kev huv ntawm ib puag ncig.

Tsev tsim khoom

Dua, polyethylene yog thawj cov khoom siv rau kev tsim cov hnab nrog tes thiab lwm yam tshwj xeeb lossis hauv tsev ntim khoom. Lub tes tsho, nyob rau hauv lem, yog ib tug derivative ntawm cov txheej txheem rau tau txais cov ntaub ntawv film. Rau nws cov khoom siv, cov yas granules nrog qee yam ntxwv zoo yog siv. Thaum lub sij hawm melting txheej txheem, lub tes tsho polyethylene yog tsim rau ntim rau hauv daim ntawv ntawm ib zaj duab xis. Yav tom ntej, cov tuam txhab lag luam tuaj yeem faib cov yob rau hauv ntu, tsim cov khoom lag luam ib nrab rau lub hnab ntim puv nrog cov leeg.

txhawm rau kom muaj zog, cov tuam txhab lag luam kuj tseem ntxiv cov khoom siv tshwj xeeb, cov khoom siv yas thiab cov hloov pauv rau thawj qhov sib xyaw. Yog li ntawd, lub tes tsho polyethylene tau txais kev txhim kho tensile lub zog zoo. Tsis tas li ntawd, cov txheej txheem thev naus laus zis tuaj yeem suav nrog kev luam ntawv thiab tsim cov folded inserts. Tab sis cov haujlwm no feem ntau yog ua raws li kev txiav txim tshwj xeeb.

Ntse

Qhov ntev ntawm pob feem ntau tsis kho - lub tes tsho yog tsim nyob rau hauv ib thooj. Raws li rau qhov dav, feem ntau hom yog 20, 30 thiab 40 cm, txawm hais tiasnyob ntawm qhov muaj peev xwm ntawm cov cuab yeej siv, txoj hauv kev no ntawm cov qauv loj tuaj yeem nce ntxiv. Nyob rau hauv cov nqe lus ntawm thickness, feem ntau ntawm cov yeeb yaj duab haum rau hauv thaj tsam ntawm 30-200 µm. Txawm hais tias cov qauv nyias nyias, lub tes tsho polyethylene tuaj yeem tiv taus cov khoom hnyav - ntau kaum kilograms. Nws yog ib qho tseem ceeb uas cov ntaub ntawv ua los ntawm cov khoom siv rov ua dua polyethylene muaj cov khaubncaws sab nraud povtseg, uas tseem ua rau cov yam ntxwv muaj zog.

Nkauj Ntxawm Tsab

Raws li twb tau sau tseg lawm, cov yam ntxwv ntawm polyethylene tau txiav txim siab rau qhov loj los ntawm cov khoom ntxiv uas tau qhia thaum lub sijhawm tsim khoom. Hauv particular, zawv zawg modifiers endow cov khoom nrog qis coefficient ntawm kev sib txhuam. Qhov no yooj yim qhib lub tes tsho, muab zaj duab xis ib qho ci ci, tab sis tib lub sijhawm tshem tawm cov nyhuv zoo li qub. Tshwj xeeb tshaj yog txhawm rau tiv thaiv cov phab ntsa sab hauv ntawm cov khoom siv, cov khoom siv los tiv thaiv kev thaiv kuj tseem siv tau. Nrog xws li ib qho ntxiv, zaj duab xis tsis tsuas yog tshem tawm cov nyhuv sticking, tab sis kuj tau txais qhov roughness ntawm qhov chaw. Txoj kev muab kev tiv thaiv sab nraud, uas yog ntxiv nrog polyethylene zaj duab xis, kuj muaj ntau. Lub tes tsho, hauv kev ua cov nplaim hluav taws tau siv, piv txwv li, tiv taus hluav taws. Lub hauv paus ntsiab lus ntawm kev tua hluav taws yog siv los ntawm kev qhia cov txheej txheem silicate uas tsim cov txheej carbonaceous. Raws li qhov tshwm sim, lub refractory barrier yog tsim, uas kuj tiv thaiv kev tso tawm ntawm volatile khoom thaum combustion.

khoom nqi

Feem ntau cov tuam txhab tsim nqi hauvtus kheej, tsom mus rau qhov tsis muaj kev txiav txim tshwj xeeb. Tus nqi cuam tshuam los ntawm qhov ntev ntawm daim ntaub, thiab lub thickness, nrog rau cov khoom ua haujlwm uas cov yeeb yaj kiab polyethylene tau txais txiaj ntsig nrog. Tus nqi ntawm rolls nrog ib tug dav ntawm 15 mus rau 150 cm nruab nrab yog 180-200 rubles ib 1 kg. Nyob rau hauv cov ntaub ntawv no, lub thickness yuav txawv ntawm 40 mus rau 120 microns. Ib zaj duab xis tuab tuaj yeem nce tus nqi los ntawm lwm 50 rubles. ib kilogram, tab sis txawm nyob ntawm no ntau nyob ntawm qhov ntim ntawm qhov kev txiav txim.

Cov khoom me me hauv daim ntawv lub tes tsho nrog qhov dav ntawm 6 txog 15 cm kuj tseem muaj. Txawm li cas los xij, muaj ntau lub tuam txhab lag luam uas siv cov ntawv me me polyethylene. Tus nqi nyob rau hauv cov ntaub ntawv no twb yog 250-300 rubles ib 1 kg. Tus nqi nce yog vim qhov nyuaj ntawm cov txheej txheem ntawm kev tsim cov yob nrog qhov dav me me.

Zaj lus

Nrog kev pab los ntawm cov khoom siv ua los ntawm polyethylene, nws muaj peev xwm muab ob qho tib si kev tiv thaiv kev tiv thaiv ntawm cov khoom thiab tiv thaiv nws los ntawm kev raug kub siab nrog cov av noo. Nyob rau tib lub sijhawm, cov kws tshaj lij thev naus laus zis siv zog kom tau txais cov txiaj ntsig kev ua tau zoo tshiab ntawm cov khoom siv vim kev hloov kho kom zoo dua qub. Tshwj xeeb, yog tias koj npaj yuav siv lub tes tsho polyethylene nyob rau hauv qhov chaw raug tshav ntuj, koj yuav tsum tau xyuam xim rau cov ntsiab lus ntawm lub teeb stabilizers hauv cov qauv. Yog li, yog tias cov yeeb yaj kiab tau yuav los npog lub tsev cog khoom, ces lub hnub qhib yuav tsis ua mob rau lub tshav kub-resistant txheej. Hloov pauv, khaws ciaelasticity thiab lub zog ntawm qhov kub thiab txias, siv ib zaj duab xis uas muaj Frost-resistant additives.
