Dab tsi yog qhov txawv ntawm cov hnab ntim khoom noj thiab cov hnab yas zoo tib yam?

Lub hnab yas yog ib qho ntawm cov khoom siv tseem ceeb hauv lub neej
Cov khoom ntim khoom noj tseem ceeb yog polyethylene, polypropylene, polystyrene, thiab lwm yam. Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv, thiab kev siv yuav tsum yog raws li cov yam ntxwv ntawm cov khoom noj nws tus kheej.

1. Polyethylene: Cov khoom tseem ceeb yog polyethylene resin, thiab ib qho me me ntawm cov roj nplua nyeem, cov neeg laus laus thiab lwm yam khoom siv ntxiv.Polyethylene yog ib qho tsis muaj ntxhiab, tsis muaj tshuaj lom, muaj mis nyuj dawb waxy khoom.HDPE muab faib ua high-density polyethylene, low-density polyethylene thiab linear low-density polyethylene raws li morphology, cov ntsiab lus thiab cov qauv saw ntawm cov polymer.
Polyethylene yas feem ntau hu ua hauv qab siab HDPE.Piv nrog tsawg-ntom polyethylene tsawg polyethylene thiab LLDPE, Polyethylene Strastics muaj ntau dua kub siab, tua vapor hydrophilicity thiab kev nyuaj siab nthuav tawm hauv ib puag ncig ib puag ncig.Tsis tas li ntawd, polyethylene yas muaj lub zog dielectric zoo heev, cuam tshuam tsis kam thiab ua haujlwm txias.Nws yog tsim rau cov khoom hollow (xws li iav fwj, lub raj mis detergent), txhaj tshuaj molding, txhaj tshuaj molding thiab lwm yam lag luam.
Linear low-density polyethylene (LINEARLOWDENSYPOYETHYLENE, LLDPE) yog ib qho polymer uas tsim los ntawm polymerization ntawm ethylene thiab ib qho me me ntawm cov olefins siab heev nyob rau hauv lub xub ntiag ntawm catalyst.Nws cov tsos zoo ib yam li cov polyethylene low-density, tab sis nws nto gloss yog zoo, tsis tshua muaj kub elongation thiab siab Modulus, dabtsi yog khoov tsis kam, tsis kam mus rau hauv av kev nyuaj siab tawg, tsis tshua muaj kub compressive zog thiab lwm yam zoo.
Nws yog tsuas yog siv rau kev txhaj tshuaj molding, extrusion, tshuab moulding thiab lwm yam molding txoj kev los tsim cov yeeb yaj kiab, khoom siv txhua hnub, kav dej, xov hlau thiab cables.
2. Polypropylene: Cov khoom tseem ceeb yog polypropylene cob, uas muaj gloss siab thiab lub teeb transmittance.Lub tshav kub sealing kev ua tau zoo dua li PE, tab sis zoo dua li lwm cov ntaub ntawv yas.
1. Kev ua tau zoo ntawm kev ua haujlwm zoo dua PE, nws lub zog, hardness thiab rigidity zoo dua li PE;
2. Kev noj qab haus huv thiab kev nyab xeeb siab dua li kev ua kis las
3. Nws muaj kev tiv thaiv kub zoo heev thiab tuaj yeem siv tau ntev ntawm qhov kub ntawm 100 degrees Celsius, tab sis nws qhov kev tiv thaiv txias tuaj yeem txhim kho qhov kev ua tau zoo ntawm HDPE thiab ua nkig ntawm -17 degrees Celsius.
Lub hnab ntim khoom ua los ntawm cov yas zaj duab xis yog superior rau platinum, pob tshab raw cov ntaub ntawv thiab kua muag-resistant cov ntaub ntawv nyob rau hauv cov nqe lus ntawm hnav tsis kam thiab noo noo kuj, tab sis lub ntim printing nyhuv yog tsis zoo thiab tus nqi yog tsawg.Nws tuaj yeem siv rau qhov thim rov qab ntim ntawm lollipops thiab khoom noj txom ncauj.Nws tuaj yeem ua rau cov zaub mov kub shrinkable zaj duab xis ntim cov hnab ntim khoom noj khoom haus, xws li cov khoom noj thiab cov hnab ntim khoom noj thiab lwm cov hnab ntim khoom sib xyaw.
3. Polystyrene: Ib qho polymer nrog styrene monomer ua cov khoom tseem ceeb.Cov khoom no yog pob tshab thiab ci iab.
1. Cov dej tsis zoo yog qhov phem dua li PE, tshuaj lom neeg ruaj khov yog qhov dav, hardness siab, tab sis brittleness loj.
2. Zoo tsis kub tsis kam, tab sis tsis zoo kub tsis kam, tsis tuaj yeem siab tshaj 60≤80 ℃.
3. Kev nyab xeeb zoo.
