Dab tsi Raw Materials Koj siv los ua cov hnab yas?
Nov 13, 2024| Cov khoom siv hnab yas peb feem ntau siv yog raws li hauv qab no:
Polyethylene (PE), hu ua PE. Nws yog ib tug siab molecular organic compound tau los ntawm ntxiv polymerization ntawm ethylene. Polyethylene tau lees paub tias yog cov khoom siv zoo tshaj plaws rau kev sib cuag zaub mov hauv ntiaj teb. Tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj ntxhiab, ua raws li cov qauv kev noj qab haus huv. Polyethylene zaj duab xis, lub teeb thiab pob tshab, nrog noo noo, oxygen, acid, alkali, huab cua nruj, kub sealing thiab lwm yam khoom. Paub tias yog "yas paj" rdquo; Nws yog cov khoom tseem ceeb tshaj plaws thiab tseem ceeb tshaj plaws rau kev ntim khoom yas.
LDPE-- polyethylene tsawg ntom ntom
Tsawg-density polyethylene, hu ua LDPE, yog ntau yam loj tshaj plaws hauv kev ntim khoom yas thiab luam ntawv hauv ntau lub teb chaws. Lub ntiajteb txawj nqus yog 0.92 ~ 0.93, uas tuaj yeem ntab hauv dej. Tsawg crystallinity (60%), bulk polymerization ntawm lub siab ntawm 1000-3000kg / cm2, yog li nws tseem hu ua high-pressure polyethylene. Ntawm 23 degrees Celsius, qhov ceev yog nyob ib ncig ntawm 0.92. Lub calendering formability tsis zoo, thiab nws yog qhov tsim nyog rau kev ua cov yeeb yaj kiab tubular los ntawm txoj kev tshuab moulding. Muaj feem xyuam rau cov ntim khoom noj, ntim fiber ntau, thiab ntim tshuaj txhua hnub.
HDPE-- siab ceev polyethylene
High density polyethylene, hu ua HDPE. Qhov ceev yog los ntawm {{0}}.941 txog 0.965 g/cm 3 . Nws yog ua los ntawm tsis tshua muaj siab polymerization, yog li nws tseem hu ua tsis tshua muaj siab polyethylene. Nws yog milky dawb, qhia tsis zoo gloss. Cov yeeb yaj kiab ua tiav tuaj yeem ua tshuab molded thiab T-tuag extruded. Thaum tshav kub kub-resistant thiab resistant rau kev ua noj, txias thiab khov-resistant, noo noo-pov thawj, roj-pov thawj, zoo rwb thaiv tsev kev ua tau zoo, thiab tsis yooj yim rau tawg. Feem ntau yog cov khw muag khoom noj khoom haus lub hnab ntim khoom thiab hnab yas tsho khuam.
PVC --polyvinyl chloride
Polyvinyl chloride yog abbreviated li PVC thiab nws cov mis molecular yog (CH-CH) n. Nws yog hom tseem ceeb tshaj plaws ntawm vinyl polymer thiab yog cov yas loj thib ob hauv ntiaj teb tom qab polyethylene. Kev tsim khoom hauv tsev yog qhov siab tshaj plaws hauv cov yas. Hauv kev lag luam luam ntawv, polyvinyl chloride xim calendered zaj duab xis thiab pob tshab glazing zaj duab xis feem ntau yog siv los ua ntim thiab kho kom zoo nkauj ntawm cov phau ntawv, folders, daim pib thiab lwm yam.
Shrinkfilm --shrink film
Shrink zaj duab xis yog ib zaj duab xis thermoplastic uas ncab thiab taw qhia thaum lub sij hawm tsim khoom thiab shrinks thaum kho cua kub los yog infrared irradiation thaum siv. Tom qab kev kho cua sov, zaj duab xis yog nruj nreem qhwv ib ncig ntawm lub pob, thiab lub zog shrinkage ncav cuag qhov siab tshaj plaws thaum lub caij txias thiab tuaj yeem khaws cia rau lub sijhawm ntev.
BOPP--biaxially taw qhia polypropylene zaj duab xis
Biaxially stretched polypropylene zaj duab xis, tseem hu ua biaxially oriented polypropylene zaj duab xis, cov lus Askiv abbreviation code BOPP, uas yog tus cwj pwm los ntawm tensile molecular orientation, txhua yam muaj zog, folded lub zog, roj ntom, noo noo barrier kuj yog superior rau zoo tib yam yas zaj duab xis. Tus nqi tsev yog qis dua li ntawm cellophane piv rau cellophane. Vim yog qhov zoo tshaj plaws ntawm cov yeeb yaj kiab, cov xim luam tawm tom qab luam ntawv tshwj xeeb yog ci thiab zoo nkauj, thiab yog ib qho tseem ceeb substrate rau yas composite saj zawg zog ntim.
