Ntau cov yeeb yaj kiab feem ntau siv nyob rau hauv lub neej txhua hnub. Cov khoom dab tsi yog cov yeeb yaj kiab ua los ntawm? Cov yam ntxwv ua tau zoo li cas ntawm txhua tus? Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau cov zaj duab yas yas tau siv hauv lub neej txhua hnub:
Cov zaj duab xis yas yog ib zaj duab xis ua los ntawm polyvinyl chloride, polystyrene thiab lwm yam resins, kev tsim kho, thiab ua txheej txheej txheej, thiab lwm yam.
Yas zaj duab xis tuaj yeem faib ua
-Zaj duab xis: Blown zaj duab xis, calendered zaj duab xis, ncab zaj duab xis, nrum zaj duab xis, thiab lwm yam;
- Agricultural Shed zaj duab xis, Mulch zaj duab xis, thiab lwm yam .;
-Films rau ntim khoom (suav nrog cov duab sib xyaw rau cov tshuaj ntim khoom siv, cov yeeb yaj kiab sib xyaw rau cov khoom noj ntim khoom, thiab lwm yam).
Cov txiaj ntsig zoo thiab qhov tsis zoo ntawm zaj duab xis yas:
Cov yam ntxwv zoo ntawm cov yeeb yaj kiab yas
Biaxouse Oriented Polypropylene Zaj Duab Xis (BOPP)
Polypropylene yog ib qho thermoplastic resin tsim los ntawm cov polymerization ntawm propylene. Cov ntaub ntawv copolymer muaj cov cua sov qis dua kub (100 ° C) Tus Vicat Muag Softing Kub ntawm PP yog 150 ° C. Vim tias qib siab ntawm crystallinity, cov khoom no muaj heev zoo nto stiffness thiab kos tiv thaiv cov khoom. PP tsis muaj kev ntxhov siab ib puag ncig kev ntxhov siab.
Biaxouse Oriented Polypropylene Zaj Duab Xis (Bopp) yog lub pob tshab siv hluav taws xob hloov tau muaj nyob hauv 1960s. Nws siv cov kab tshwj xeeb rau kev sib xyaw polypropylene raw khoom thiab ua haujlwm ntxiv, yaj thiab muab lawv pov rau hauv cov yeeb yaj kiab. Nws yog dav siv nyob rau hauv cov khoom noj, khaub noom, luam yeeb, tshuaj yej, mis nyuj, textiles, thiab muaj lub npe ntawm "ntim poj huab tais". Tsis tas li ntawd, nws tseem tuaj yeem siv rau kev npaj ntawm cov khoom muaj nuj nqis ntxiv rau cov khoom siv hluav taws xob thiab cov microstrical cov lus qhia ntawm cov yeeb yaj kiab hauv cov yeeb yaj kiab yog qhov dav heev.
BOPP zaj yeeb yaj kiab tsis yog muaj qhov zoo ntawm qhov ceev, zoo corrosity, tab sis kuj muaj lub zog kho qhov muag zoo, muaj zog dua thiab muaj txiaj ntsig ntawm cov khoom nyoos. BOP cov zaj duab xis tuaj yeem ua ke nrog lwm cov ntaub ntawv nrog cov khoom tshwj xeeb txhawm rau txhim kho lossis txhim kho kev ua haujlwm. Cov ntaub ntawv siv feem ntau suav nrog PE Zaj duab xis, salivating polypropylene (CPP) zaj duab xis, polyvinylidene chloride (PVDC), zaj duab xis txhuas, thiab lwm yam duab.
Tsawg qis ntom ntom polyethylene zaj duab xis (ldpe)
Polyethylene zaj duab xis, yog PE, muaj cov yam ntxwv ntawm noo noo tsis kam thiab noo noo permeability.
Tsawg-ntom polyethylene (LPDE) yog cov hluavtaws resin tau los ntawm ethylene radical polymerization nyob rau hauv kev kub siab, yog li nws tseem hu ua "high-siab polyethylene". LPDE yog ib lub ceg ntoo molecule nrog cov ceg ntawm cov ceg sib txawv ntawm cov saw tseem ceeb, nrog rau 15 mus rau ceg ethyl lossis ntev dua nyob rau hauv lub saw tseem ceeb. Vim tias cov molecular chain muaj ntau dua cov saw, cov khoom lag luam tsis tshua muaj zog, muaj zog acidizing acids), alkali, muaj hluav taws xob rwb thaiv tsev, muaj hluav taws xob rwb thaiv tsev. Translucent thiab glossy, nws muaj cov tshuaj ruaj khov rau kev ruaj khov, kev kub hnyiab, dej tsis kam, thiab muaj peev xwm boiled. Nws lub ntsiab tsis zoo yog nws txoj kev txom nyem rau oxygen.
Nws yog feem ntau siv los ua cov ntaub ntawv ntim txheej sab hauv ntawm cov khoom ntim sib xyaw, thiab nws tseem siv ntau tshaj li 40% ntawm kev noj ntawm cov khoom siv yas ntim yas. Muaj ntau ntau hom yeeb yaj kiab Polyethylene Ntim cov yeeb yaj kiab, thiab lawv cov kev ua yeeb yam tseem txawv. Kev ua yeeb yam ntawm ib txheej duab zaj duab xis yog ib leeg, thiab kev ua yeeb yam ntawm kev sib dhos ua yeeb yaj kiab yog ua kom tiav. Nws yog cov khoom siv tseem ceeb ntawm cov khoom noj ntim khoom. Qhov thib ob, polyethylene zaj duab xis tseem siv hauv kev ua teb ntawm pej xeem engineering, xws li geomembrane. Nws ua raws li lub cev dej tsis muaj dej hauv cov pej xeem engineering thiab muaj permeability tsawg. Ua yeeb yaj kiab ua liaj ua teb yog siv hauv kev ua liaj ua teb
Polyester Zaj Duab Xis (Tsiaj)
Polyester Zaj Duab Xis (Tsiaj), feem ntau hu ua polyethylene terepthalate, yog ib thermoplastic engineering tshuab yas. Nws yog cov zaj duab xis ua cov khoom siv tuab los ntawm extrusion thiab ces biaxivly ncab. Polyester zaj duab xis yog tus cwj pwm los ntawm cov kws kho mob zoo nkauj, kev sib txhuam, cov roj ua tsis kam, cua nruj thiab tsw qab. Ib qho ntawm daim duab sib dhos ua si tas mus li, tab sis cov corona tsis yog qhov zoo.
Tus nqi ntawm Polyester zaj duab xis yog tus muaj siab, thiab nws cov tuab tuab yog feem ntau 0.12 hli. Nws yog feem ntau siv los ua cov khoom siv sab nraud ntawm cov khoom noj kom ntim khoom, thiab muaj cov ntawv luam tawm zoo. Tsis tas li ntawd, Polyester zaj duab xis feem ntau siv tau luam tawm thiab ntim cov ntaub ntawv ua ke, thiab yog siv fiber ntau cov ntaub ntawv, luam ntawv, luam ntawv, thiab tshuaj thiab kev noj qab haus huv.
Nylon yas zaj duab xis (ony)
Lub npe tshuaj lom neeg ntawm Nylon yog polyamide (pa). Tam sim no, muaj ntau ntau yam ntawm Nylon Industrial kev lag luam, thiab lub zog ci ua kom zoo, thiab cov cua sov zoo heev, cov tshuaj tiv thaiv zoo, roj tsis kam thiab cov organic tsom kho. Cov hnav zoo heev thiab cov khoom mos tsis haum, cov khoom siv dej tsis zoo, cov khoom noj noo noo, cov zaub mov tsis zoo, cov zaub mov tsis huv, thiab lwm yam.
Nrum polypropylene zaj duab xis (CPP)
Tsis zoo li cov kab lis kev cai biaxously oriented polypropylene zaj duab xis (Bopp) txheej txheem, lub cam khwb, tsis-taw tiaj extrusion zaj duab xis tsim los ntawm yaj casting thiab quenching. Nws yog cov yam ntxwv yooj yim ntau lawm nrawm, cov zis siab siab, cov yeeb yaj kiab zoo pob tshab, thiab sib npaug zoo ntawm cov khoom muaj ntau yam. Vim tias nws yog tiaj tus extruded zaj duab xis, ua haujlwm taug qab xws li luam ntawv thiab compound yog yooj yim heev. CPP yog dav siv nyob rau hauv lub ntim ntawm textiles, paj, zaub mov noj, thiab muaj tas.
Aluminium-Coated yas zaj duab xis
Cov yeeb yaj kiab Aluminized no muaj ob qho tib si ntawm cov yam ntxwv ntawm cov yeeb yaj kiab yas thiab cov yam ntxwv ntawm cov hlau. Lub luag haujlwm ntawm txhuas plating rau saum npoo ntawm zaj duab xis yog los tuav lub teeb ci, uas tsis tsuas yog ncua lub neej txee ntawm cov ntsiab lus, tab sis kuj tseem tab tom ci ntawm zaj duab xis. Yog li no aluminium zaj duab xis yog dav siv nyob rau hauv kev ntim khoom, feem ntau yog siv nyob rau hauv qhuav thiab puffed zaub mov ntim xws li ntim khoom ntawm qee cov tshuaj thiab tshuaj pleev ib ce.
