Cling zaj duab xis xaiv txoj kev

Thaum muas lub crisper los yog yas qhwv, nco ntsoov xyuas seb nws puas tau cim nrog lub npe tshwj xeeb lossis cov qauv tshuaj. Yog tias tsuas muaj lub npe Askiv thiab tsis muaj lub logo Suav, cov khoom yuav tsum tau yuav nrog ceev faj. Nyob rau tib lub sijhawm, nco ntsoov xaiv cov khoom uas sau tias "zaub mov".

Lub crisper yog tsim los ntawm polyethylene (PE) thiab polypropylene (PP). Tus nqi sib txawv ntawm ob yam khoom tsis loj, tab sis polypropylene (PP) tuaj yeem tiv thaiv kev nkag mus ntawm cov roj zoo dua.

Thaum muas yas qhwv, nws raug nquahu kom yuav tus kheej- nplaum nplaum zaj duab xis ua los ntawm polyethylene (PE), tshwj xeeb tshaj yog thaum khaws cov nqaij, txiv hmab txiv ntoo, thiab lwm yam, vim muaj kev nyab xeeb, PE qhwv yog qhov nyab xeeb tshaj plaws . . Yog tias koj xav tau lub neej txee ntev dua, nws raug nquahu kom xaiv polyvinylidene chloride (PVDC) vim tias cov khoom siv clinging tau zoo dua lub neej ntev thiab kev ua haujlwm zoo tshaj plaws zaj duab xis ntawm peb cov ntaub ntawv. Polyvinyl chloride (PVC) cling zaj duab xis muaj qhov zoo transparency, zoo viscosity, zoo elasticity thiab tus nqi qis, yog li nws tau dhau los ua kev xaiv ntawm ntau tus neeg, tab sis nws yuav tsum tau muab sau tseg tias nws tsis tuaj yeem siv rau kev khaws cia cov khoom noj muaj roj vim nws yog ua los ntawm poly A resin muaj li ntawm vinyl chloride resin, plasticizer thiab antioxidant tsis muaj tshuaj lom los ntawm nws tus kheej. Txawm li cas los xij, cov khoom siv tseem ceeb xws li plasticizers thiab anti-cov neeg ua haujlwm laus raug ntxiv. Cov plasticizers hauv txhua hnub - siv polyvinyl chloride plastics feem ntau yog siv dibutyl terephthalate thiab dioctyl phthalate. Cov tshuaj no yog tshuaj lom, thiab cov roj hauv cov zaub mov tuaj yeem yooj yim yaj cov plasticizer "ethyl ammonia" hauv cov hnab yas, uas muaj kev puas tsuaj loj rau tib neeg endocrine system thiab tuaj yeem cuam tshuam cov tshuaj hormone metabolism hauv tib neeg lub cev. Kuj tseem muaj polyvinyl chloride los tiv thaiv - cov neeg ua haujlwm laus cov hmoov lead stearate ntsev uas yog tshuaj lom. Lead- ntsev- muaj cov khoom siv polyvinyl chloride (PVC) nrog ethanol, ether thiab lwm cov kuab tshuaj yuav ua rau cov hmoov lead. Thaum cov ntsev leads - muaj cov polyvinyl chloride yog siv los ua cov ntim khoom noj thiab ua tau raws li cov khoom siv fritters, kib ncuav, kib ntses, cov nqaij siav, thiab khoom noj txom ncauj, nws yuav ua rau cov hlau lead molecules mus rau hauv cov roj, yog li PVC hnab yas siv tsis tau. Cov zaub mov muaj roj. Tsis tas li ntawd, nws yuav tsum tsis txhob muab tso rau hauv lub qhov cub microwave thiab yuav tsum tsis txhob siv qhov kub thiab txias Vim tias cov khoom siv yas polyvinyl chloride yuav maj mam decompose hydrogen chloride gas ntawm qhov kub thiab txias, xws li txog 50 ° C, cov roj no muaj teeb meem rau tib neeg lub cev, yog li cov khoom siv PVC yuav tsum tsis txhob siv los ua cov khoom ntim khoom noj.
