Dab tsi yog Cov Khoom Noj Qib Plastics

PP RESIN:

PP cov ntaub ntawv feem ntau yog hais txog polypropylene, uas yog ib qho polymer ntawm propylene los ntawm cov tshuaj tiv thaiv polymerization ntxiv. Dawb waxy khoom, pob tshab thiab lub teeb nyob rau hauv tsos.

PP yas yog ib qho ntawm cov yas ntau heev, tuaj yeem ua rau hauv cov khoom noj yas ntim khoom noj, xws li cov khoom noj tshwj xeeb cov hnab yas, cov thawv ntim khoom noj, cov khoom noj khoom haus, cov khoom noj yas, thiab lwm yam, muaj kev nyab xeeb thiab tsis muaj tshuaj lom thiab tsis kub tsis kam, Qhov kub thiab txias tsis kam, PP yog tib lub yas uas tuaj yeem muab tso rau hauv lub qhov cub microwave cua sov, thiab muaj lub zog folding kev ua tau zoo (50,{2}} zaug), Nws yuav tsis raug puas tsuaj thaum ntog los ntawm qhov siab ntawm {{ 3}} degree.

Nta: Nws yog cov thermoplastic resin, nrog rau cov cua kub zoo heev thiab cov dej noo tsis kam, feem ntau siv hauv microwave ntim khoom noj, instant noodle khob, soy sauce fwj thiab lwm yam.

Kev nyab xeeb: PP kuj yog cov khoom noj khoom haus qib yas, dav siv hauv kev ntim khoom noj, nyab xeeb thiab txhim khu kev qha.

 

PE RESIN

Polyethene (PE) yog cov thermoplastic resin ua los ntawm kev sib sau ethylene. Hauv kev lag luam, nws kuj suav nrog copolymer ntawm ethylene nrog me me ntawm alpha-olefin.

HDPEyas, feem ntau hu ua high-density polyethylene, muaj kev siv siab kub, hardness, mechanical zog thiab tshuaj tiv thaiv. Nws yog cov khoom siv tsis muaj tshuaj lom thiab muaj kev nyab xeeb, feem ntau siv los tsim cov thawv yas rau khoom noj.

LDPEyas yog feem ntau hu ua low-density polyethylene, thiab cov khoom ua nrog nws muaj cov yam ntxwv ntawm tasteless, odorless, non-toxic thiab dull nto. Feem ntau siv rau hauv cov khoom noj khoom haus yas, ntim khoom noj nrog cov yeeb yaj kiab sib xyaw, cov khoom noj khoom haus cling zaj duab xis, tshuaj, tshuaj ntim tshuaj, thiab lwm yam.

Nta: Nws muaj cov cua kub zoo, tiv thaiv txias thiab corrosion kuj, thiab feem ntau yog siv rau ntim zaub, txiv hmab txiv ntoo, dej haus thiab lwm yam khoom noj.

Kev nyab xeeb: PE yog cov khoom ntim khoom siv dav siv, nws txoj kev nyab xeeb yog siab, raws li cov qauv khoom noj khoom haus qib yas.

 

PCRESIN

Polycarbonate (PC luv luv) yog ib qho polymer uas muaj carbonate ester pawg hauv cov saw molecular. Raws li cov qauv ntawm pawg ester, nws tuaj yeem muab faib ua aliphatic, aromatic, aliphatic - aromatic thiab lwm yam.

PC yas tuaj yeem siv los ua cov dej kis las, lub raj mis, thiab lwm yam, dav siv hauv kev tsim cov thawv yas, yog cov khoom siv zoo.

 

PS RESIN

Polystyrene series plastics hais txog ib chav kawm ntawm cov yas xws li styrene pawg hauv cov saw hlau macromolecular, suav nrog styrene thiab nws cov copolymer, cov hom tshwj xeeb suav nrog polystyrene (GPPS), siab cuam tshuam polystyrene (HIPS), hloov pauv tau polystyrene (EPS) thiab metallocene polystyrene (SPS)

PS feem ntau yog siv los ua lub tais instant noodle lub thawv, cov thawv ntim khoom noj ceev, cov thawv ntim khoom pov tseg, thiab lwm yam, nrog rau qhov txias txias.

Nta: Nws muaj cov pob tshab zoo, lub zog thiab qhov kub thiab txias, thiab feem ntau yog siv rau ntim pastry, khoom qab zib, kas fes thiab lwm yam khoom noj.

 

Hais txog kev nyab xeeb, PE, PP, PET thiab PS tag nrho yog cov khoom noj-qib yas, uas ua tau raws li cov qauv hauv lub tebchaws thiab muaj kev nyab xeeb siab.

Cov khoom ntim cov khoom noj sib txawv muaj cov yam ntxwv sib txawv thiab qhov kev thov. Piv txwv li, PE thiab PP yog haum rau ntim ntau yam khoom noj, nrog rau cov nqaij, ntses, zaub, txiv hmab txiv ntoo, dej haus, thiab lwm yam.; PET yog siv los ntim cov dej haus, dej ntxhia, thiab lwm yam. PS yog tsim rau ntim pastry, khoom qab zib thiab lwm yam khoom noj.

Thaum xaiv cov khoom ntim yas ntim khoom noj, ntxiv rau kev txiav txim siab nws txoj kev nyab xeeb, nws tseem yuav tsum tau ua kom tiav kev xaiv raws li cov yam ntxwv ntawm cov khoom noj, kev cia khoom, kev thauj mus los thiab lwm yam.
