Cov ntaub ntawv Polymeric tau tsim nyog tau txais kev pom zoo thiab muaj txiaj ntsig zoo. Vim nws cov yam ntxwv, zaj duab xis polyethylene tau yog ib tus neeg sib tw loj rau lwm cov khoom ntim ntau xyoo. Nws qhov zoo thiab txiaj ntsig yog dab tsi?

Nws yog dab tsi?

Nws nyuaj rau xav txog kev lag luam niaj hnub no uas tsis siv cov polymers. Polyethylene tau dhau los ua ib qho yooj yim tshaj plaws, yog li nws nkag tau sai thiab khov kho hauv lub neej txhua hnub . Nws kuj tseem hloov nws cov khoom tsis txawv txav kom ntsws zaj duab xis - cov ntim khoom nrov tshaj plaws.

Kev lag luam tshuaj lom neeg yog nyob rau tus as khauj tshwj xeeb, yog li ntawd cov khoom lag luam thiab cov khoom siv los ntawm polyethylene raug tswj hwm los ntawm cov cai sib cais . Kev tsim khoom, siv thiab khaws cia ntawm cov yeeb yaj kiab tau piav qhia hauv daim ntawv GOST 25951-83. Piv txwv li, muaj pes tsawg leeg, tus yam ntxwv kub, cov khoom ntawm cov ntaub ntawv pov thawj, txheej txheem ntim ntawm zaj duab xis nws tus kheej, thiab txawm tias cov yam ntxwv khaws cia tau piav qhia.

Tsuas yog cov chaw tsim khoom lag luam uas ua raws txhua qhov xwm txheej no tuaj yeem lav qhov kev nyab xeeb ntawm zaj duab xis rau cov neeg ua haujlwm ntawm cov tuam txhab thiab cov neeg siv khoom kawg - txhua tus neeg uas ua haujlwm nrog cov khoom no lossis siv nws txhua hnub.

Cov muaj pes tsawg leeg ntawm polyethylene cuam tshuam rau nws qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom, thiab lub zog. Lub npe "shrinkable" zaj duab xis yog vim nws cov khoom kub tshwj xeeb . Piv txwv li, nws tseem ruaj khov ntawm + 30º -50º С - nws tsis decompose lossis deform. Nws yog txog qib no uas huab cua qee zaum ua rau lub caij sov. Yog tias zaj duab xis raug rau qhov kub siab (ntsws hauv kev lag luam tau ua tiav los ntawm cua sov + 120º-150º С), tom qab ntawd cov khoom pib hloov pauv nws cov duab. Nws dhau los ua yas thiab ntsws lossis ntsws. Nrog cov txiaj ntsig no, polyethylene rov ua dua cov khoom sib txuas, qhwv lawv zoo li cov ntaub tuab tuab, thiab tsis nyob hauv kev sib cuag nrog cov khoom no. Ua tsaug rau cov txiaj ntsig no, nws muaj peev xwm ntim cov khoom ntawm ntau yam duab thiab yam ntxwv.

Cov ntim khoom muaj cov yam ntxwv tshwj xeeb: nws tau ntim, tiv taus kev puas tsuaj rau cov khoom siv, tsim cov txheej tuab thiab muaj zog, sab hauv, yog tias tsim nyog, koj tuaj yeem txhim kho cov khoom xws li cov kaus poom, fwj lossis hnab. Los ntawm cov pob tshab polyethylene, nws yooj yim pom cov ntsiab lus tsis tau qhib lub thawv tiv thaiv, kom pom cov cim, xim, xwm txheej.

Nrog cov txiaj ntsig zoo no, zaj duab xis me me hnyav dua li lub thawv ntawv lossis ntoo pallets, thiab pheej yig dua.

Tsuas yog qhov tsis zoo - lub sij hawm ntev decomposition - tau them los ntawm qhov tseeb tias polyethylene tau rov ua dua thiab rov siv dua hauv kev tsim khoom.

Cov ntawv thov
