Yas tes tsho yam ntxwv, daim ntawv thov

Feem ntau hom ntim ua los ntawm yas zaj duab xis. Los ntawm nws yuav ua rau nrov-shirts thiab lub hnab, thiab wrapping cov ntaub ntawv rau ntau lawm. Txawm li cas los, nyob rau hauv cov nqe lus ntawm kev kab ntsab, qhov zoo tshaj plaws kev xaiv yog ib cov pob-lub tes tsho. Nws zoo xws li cov tau siv ntau lengths ntawm cov ntaub ntawv uas. Uas yog, nyob rau hauv ib co kev uas neeg siv yuav txawv qhov tsis muaj lub pob. Nyob rau tib lub sij hawm, cov yas tes tsho retains tag nrho cov zoo ntawm classic tej pob khoom, uas muaj xws li durability, yooj yim uas tuav thiab kom ntseeg tau ceev ceev.

Qhov uas siv tau rau hauv lub tes tsho ntawm polyethylene?

Tus zaj duab xis yog ib lub hauv paus rau ntxiv raug tej pob khoom. Yog li ntawd, nws yuav hu ua universal. Lub tes tsho yuav ua tau ib tug consumable khoom nyob rau hauv kev tsim kho kev lag luam, nyob rau hauv muab catering chaw thiab nyob rau hauv lub domestic kev khwv nyiaj txiag. Feem ntau, ib lub hnab yas tes tsho rau lub ntim siv nyob rau hauv daim ntaub ntawv twg nws yuav tsum mus ua hauj lwm nrog loj nyiaj ntawm cov khoom los yog khoom. Piv txwv li, rau ntim tej ntaub ntawv. Qhaj ntawv ntawm pronounced nqaws thiab perforations tso cai rau koj mus npaj tsis siv neeg ntim kab, uas tsis yuav tsum tau ib tug kev twb kev txuas cov tswv.

Hos zaj duab xis nyob rau hauv daim ntawv ntawm cov tes tsho thiab nyob rau hauv tshwj xeeb qhov chaw. Yog li ntawd, muaj yog polyethylene, uas yog Ameslikas tsim rau siv nyob rau hauv hluav taws xob xav tau kev pab. Nrog xws li ib tug pob yuav cais pab kiag li lawm thiab pab kiag li lawm los tiv thaiv lawv los ntawm dej. Tsis tas li ntawd faib yas tes tsho rau seedlings, uas yog nce yuav tsum tau nyob rau hauv cov nqe lus ntawm ib puag ncig kev dawb huv.

raug technology

Ib zaug ntxiv, cov polyethylene chiv yog ib tug raw khoom rau kev tsim tej pob khoom nrog saib xyuas thiab lwm yam tshwj xeeb los yog tsev neeg ntim. Tes Tsho, nyob rau hauv lem, - ib tug derivative ntawm tag nrho cov txheej txheem ntawm kev ua ib zaj duab xis cov ntaub ntawv uas. Rau nws lawm Plastic granules yog siv nrog rau tej kev zoo yam ntxwv. Lub melting txheej txheem yog tsim los ntawm ib lub hnab yas tes tsho rau wrapping ib zaj duab xis. Nyob rau hauv lub neej yav tom ntej, manufacturers yuav faib rau yob rau hauv daim, tsim ib tug semi-tiav lawm cov khoom rau muaj tag nrho pob nrog saib xyuas.

Nyob rau hauv thiaj li yuav nce lub dag lub zog ntawm manufacturers kuj pab txhawb rau cov thawj cov qauv ntawm tshwj xeeb additives, modifiers thiab plasticizers. Raws li ib tug tshwm sim, ib lub hnab yas tes tsho attains siab zoo tensile zog. Tsis tas li ntawd, cov raug kev tej zaum yuav muaj cov ntaub ntawv rau ntawm printing thiab creation ntawm rebate inserts. Tab sis cov no ua hauj lwm yog feem ntau yog nqa tawm los ntawm tshwj xeeb kev txiav txim.

yam ntxwv ntawm

Raws qhov ntev ntawm lub ntim yog tsis feem ntau yog tsau - lub tes tsho yog manufactured nyob rau hauv ib daim ntawv. Raws li rau lub dav, lub feem ntau tawm tswv yim rau 20, 30 thiab 40 cm, txawm hais tias nyob rau hauv lub peev xwm ntawm cov khoom ntau thiab tsawg txoj kev hauv tsev tej zaum yuav ua rau kom. Rau feem ntau films stacked thickness rau hauv lub chav 30-200 microns. Dua li ntawm qhov nyias qauv, lub yas tes tsho yuav mas siab loads - ib tug ob peb kaum ntawm kilograms. Nws yog noteworthy tias cov ntaub ntawv manufactured los ntawm siv polyethylene muaj thicker khaubncaws sab nraud povtseg, thiab cov uas ua rau yus siab zog yam ntxwv.

Ua hauj lwm thaj chaw ntawm cov zaj duab xis

Raws li sau tseg saum toj no, cov kev yam ntxwv ntawm polyethylene yog txiav txim mus rau ib tug loj raws li additives uas yog tswvcuab thaum lub sij hawm siv thiab ua. Nyob rau hauv kev, lub zawv zawg khoom modifiers pub ib tug qis coefficient ntawm tsis sib haum xeeb. Qhov no simplifies qhia ntawm lub tsho, cov zaj duab xis muab ib tug ci, tab sis nyob rau tib lub sij hawm tshem tawm cov zoo li qub nyhuv. Tshwj xeeb tshaj yog los mus tiv thaiv raws puab phab ntsa khoom siv raws li antiblocking additive. Nrog rau qhov sib ntxiv ntawm cov zaj duab xis tsis tau tsuas yog tau tshem ntawm cov nyhuv ntawm adhesion, tab sis kuj acquires nto roughness. Faib thiab txhais tau tias rau lwm tiv thaiv, uas yog complemented los ntawm ib tug polyethylene zaj duab xis. Lub tes tsho, uas yog siv nyob rau hauv qhov kev ntawm tus nplaim taws retardant, piv txwv li, resistant rau hluav taws. Hauv paus ntsiab lus hluav taws hluav yog pom tau hais los qhia cov fawm kib silicate composites, uas tsim lub carbonaceous txheej. Cov no ib tug fireproof barrier thiab kev tso tawm ntawm volatile khoom thaum lub sij hawm combustion.

Tus nqi ntawm cov khoom

Feem ntau, manufacturers tsim tus nqi ib lub zuj zus, tsom rau qhov tsis muaj ib tug txiav txim. Puas Pab Tau tus nqi thiab loj ntawm lub Web site, thiab cov thickness thiab kev kawm ntawv zog, yog muab tej txiaj ntsim nrog ib tug polyethylene zaj duab xis. Nqe yob dav ntawm 15 mus rau 150 cm nyob rau hauv nruab nrab 180-200 rubles ib 1 kg. Lub thickness yuav txawv los ntawm 40 mus rau 120 microns. Saum toj no lub tuab zaj duab xis yuav ua tus nqi tag rau 50 rubles. ib kilo, tab sis ib tug ntau nyob rau qhov kev txiav txim volume.

Faib thiab melkoformatnaya khoom nyob rau hauv daim ntawv ntawm tes tsho dav ntawm 6 mus rau 15 cm. Nrog xws li ib tug zaj duab xis peev xwm yuav tsim me me ntim hnab rau catering kev lag luam. Txawm li cas los, muaj ib tug ntau ntawm muaj Enterprises, uas siv melkoformatnaya polyethylene zaj duab xis. Tus nqi nyob rau hauv cov ntaub ntawv no yog twb 250-300 rubles ib 1 kg. Ua nqi vim lub complexity ntawm lub tsim txoj kev coils nrog me me dav.

xaus

Siv cov tswv yim cov ntaub ntawv uas cov polyethylene thiab yuav muab tau txhua yam kev pab tiv thaiv rau cov khoom thiab kev tiv thaiv nws los ntawm raug tsa kub nrog dej. Nyob rau tib lub sij hawm engineers siv zog kom tau tshiab kev ua tau zoo ntawm cov khoom vim zoo modifiers. Nyob rau hauv kev, yog tias koj npaj mus siv ib lub hnab yas tes tsho nyob rau hauv qhov chaw raug tshav ntuj, koj yuav tsum xyuam xim rau cov ntsiab lus ntawm cov qauv ntawm cov teeb stabilizers. Yog li, yog hais tias tus zaj duab xis yog yuav los npog lub tsev cog khoom, ces qhib lub hnub yuav tsis ua mob rau lub refractory txheej. Nyob rau lwm cov tes, kom tau khaws cia rau hauv lub elasticity thiab lub dag lub zog thaum uas tsis muaj kub yuav tsum tau siv zaj duab xis nyob rau hauv uas nyob tus yeees ntawm no-resistant additives yog muab.
