Tsawg yaj batch inclusion hnab yog ua los ntawm EVA (cov copolymer ntawm Ethylene thiab Vinyl Acetate) resin, yog li lawv kuj hu ua EVA hnab.EVA yog ib qho elastomeric polymer uas tsim cov ntaub ntawv uas "zoo li roj hmab" hauv softness thiab yooj. Cov khoom siv no muaj qhov pom tseeb zoo thiab gloss, tsis tshua muaj kub toughness, kev nyuaj siab-tawg tsis kam, kub-melt nplaum nplaum, thiab tiv thaiv UV hluav taws xob. Nws daim ntawv thov muaj xws li zaj duab xis, ua npuas ncauj, kub yaj nplaum, hlau thiab cable, extrusion txheej, hnub ci cell encapsulation, thiab lwm yam.
Peb cov hnab ntim qis qis thiab cov yeeb yaj kiab yog txhua yam ua los ntawm nkauj xwb EVA resin los xyuas kom meej qhov zoo ntawm cov khoom kawg. Peb siv raw cov ntaub ntawv zoo tiag tiag vim peb paub tias peb cov khoom yuav dhau los ua cov khoom me me ntawm koj cov khoom.
Tsawg melt batch inclusion hnab xa mus rau lub hnab siv los ntim cov roj hmab additives thiab tshuaj nyob rau hauv cov txheej txheem compounding. Txhawm rau xaiv lub hnab kom zoo, peb feem ntau xav txog cov hauv qab no:
- 1. Melting point
- Cov hnab uas muaj qhov sib txawv ntawm qhov sib txawv yog qhov yuav tsum tau ua rau kev sib xyaw sib txawv.
- 2. Lub cev muaj zog
- Tensile zog thiab elongation yog lub ntsiab technical tsis.
- 3. Tshuaj tiv thaiv
- Qee cov tshuaj tuaj yeem tua lub hnab ua ntej muab tso rau hauv lub tshuab tov khoom.
- 4. Thaum tshav kub kub foob muaj peev xwm
- Thaum tshav kub kub sealing lub hnab tuaj yeem ua rau lub ntim tau yooj yim dua thiab txo lub hnab ntim.
- 5. Tus nqi
- Zaj duab xis thickness thiab lub hnab loj txiav txim tus nqi.
Tej zaum koj tsuas yog qhia peb koj daim ntawv thov xav tau, cov kws tshaj lij ntawm Zonpak yuav pab koj txheeb xyuas qhov yuav tsum tau ua. Thiab nws yog ib txwm tsim nyog los sim cov qauv ua ntej daim ntawv thov ntau.
Peb tau nug cov lus nug no yuav luag txhua hnub. Lo lus teb yog "Tsis yog, peb ua tsis tau". Vim li cas? Txawm hais tias nws yooj yim rau peb tsim thiab muab cov khoom sib xws, peb nkag siab tias nws yuav ua rau cov neeg siv khoom tsis yooj yim thiab tsis tsim nyog cov khoom pov tseg. Feem ntau ntawm peb cov khoom yog cov neeg siv khoom tshwj xeeb hom thiab qhov loj me.Peb hais tus nqi rau txhua qhov kev qhia tshwj xeeb. Tus nqi sib txawv nyob ntawm seb cov khoom, daim ntawv, qhov loj, zaj duab xis thickness, embossing, venting, luam ntawv thiab kev txiav txim requriements. Ntawm Zonpak, peb pab cov neeg siv khoom txheeb xyuas cov kev xav tau thiab kho cov khoom tsim nyog nrog kev ua tau zoo tshaj plaws / nqi piv.
ZonpakTMCov hnab ntim qis thiab zaj duab xis yog tsim tshwj xeeb uas tsim cov khoom ntim ntim rau cov khoom siv roj hmab, yas thiab tshuaj lom neeg kev lag luam. Lawv muaj cov yam ntxwv nram qab no.
1. Tsawg Melting Point
EVA hnab muaj cov ntsiab lus qis melting, lub hnab nrog cov ntsiab lus sib txawv sib txawv sib txawv. Muab tso rau hauv ib lub zeb los yog tov khoom, cov hnab ntim tau yooj yim yaj thiab tawg tag nrho hauv cov khoom siv roj hmab.
2. High Compatibility nrog roj hmab thiab yas
Cov ntaub ntawv tseem ceeb uas peb xaiv rau peb lub hnab thiab zaj duab xis yog sib xws nrog cov roj hmab thiab cov yas, thiab tuaj yeem siv los ua cov khoom me me rau cov khoom sib txuas.
3. Ntau yam txiaj ntsig
Siv cov hnab EVA los ntim thiab ua ntej hnyav cov hmoov thiab cov tshuaj ua kua tuaj yeem ua kom yooj yim rau kev sib xyaw ua haujlwm, ncav cuag qhov tseeb ntxiv, tshem tawm cov yoov thiab cov kab mob sib kis, ua kom thaj chaw sib xyaw kom huv si.
Melting point feem ntau yog qhov tseem ceeb tshaj plaws los ntawm tus neeg siv thaum xaiv cov hnab ntim qis lossis cov yeeb yaj kiab rau daim ntawv thov roj hmab. Peb tsim thiab muab cov hnab thiab zaj duab xis nrog cov ntsiab lus melting sib txawv kom haum rau cov neeg siv khoom sib txawv cov txheej txheem. Melting point ntawm 70 mus rau 110 ° C. yog muaj.
