Dab tsi yog qhov kev taw qhia ntawm yasfua ilms?

Cov yeeb yaj kiab yas sawv cev rau cov chav kawm tseem ceeb ntawm cov ntaub ntawv polymeric yam ntxwv los ntawm lawv qhov nyias nyias, hloov tau yooj yim thiab thaj chaw dav dav. Cov khoom siv hluav taws xob no yog tsim los ntawm kev ua cov khoom siv polymer-xws li muab los ntawm cov roj av lossis nce los ntawm cov khoom siv txuas ntxiv-rau hauv cov ntawv txuas ntxiv nrog cov tswj nruj, qhov dav, thiab cov khoom siv kho tshuab. Lub ntiaj teb no yas zaj duab xis kev lag luam tau loj hlob exponentially txij li thaum nws pib nyob rau hauv nruab nrab-20th caug xyoo, nrog tam sim no txhua xyoo ntau lawm ntau tshaj 100 lab metric tons thoob ntiaj teb.

Lub versatility ntawm yas zaj duab xis stems los ntawm lawv cov cim ua ke ntawm cov khoom: lub teeb yuag tsis tau ruaj, saj zawg zog tsis tau muaj zog, thiab pob tshab los yog opaque nyob ntawm seb yuav tsum formulation. Cov yam ntxwv no, ua ke nrog cov nqi tsim khoom qis, tau ua rau cov yeeb yaj kiab yas tsis tuaj yeem nyob thoob plaws txhua qhov kev lag luam niaj hnub thiab lub neej niaj hnub. Los ntawm kev khaws cov khoom noj tshiab kom ua kom cov khoom siv hluav taws xob hloov tau yooj yim, cov yeeb yaj kiab yas ua haujlwm uas feem ntau pom tsis tau rau cov neeg siv khoom kawg tab sis tseem ceeb rau cov khoom lag luam thiab kev ruaj khov.

Kev nce qib tsis ntev los no hauv cov ntaub ntawv tshawb fawb tau nthuav dav lub peev xwm ntawm cov yeeb yaj kiab yas kom deb dhau lawv cov luag haujlwm ib txwm muaj. Kev tsim kho tshiab suav nrog cov yeeb yaj kiab uas hloov cov khoom hauv kev teb rau ib puag ncig stimuli, biodegradable lwm txoj rau cov pa yas, thiab cov yeeb yaj kiab ua haujlwm siab uas muaj peev xwm tiv thaiv tsis tau pom dua. Nyob rau tib lub sijhawm, kev txhawj xeeb ntawm ib puag ncig kev loj hlob tau txhawb txoj kev loj hlob ntawm cov voj voog rov ua dua tshiab thiab cov ntaub ntawv ua yeeb yaj kiab bio-based uas tswj kev ua haujlwm thaum txo kev cuam tshuam ecological.

Dab tsi ntawm cov yas zaj duab xis?

Feem ntau cov yeeb yaj kiab

Polyethylene zaj duab xis yog hom yas zaj duab xis siv dav tshaj plaws, suav txog ntau dua 40% ntawm tag nrho cov khoom siv yas. Hom thiab yam ntxwv ntawm Polyethylene Films:

1. Tsawg-Density Polyethylene Zaj duab xis (LDPE)

LDPE zaj duab xis yog cov yam ntxwv ntawm lawv qhov yooj yim, pob tshab, thiab tsis muaj tshuaj lom, tsis muaj ntxhiab tsw. Lawv muaj cov dej tsis zoo, tiv thaiv kev ya raws, thiab tshuaj lom neeg ruaj khov, ua rau lawv haum rau ntim khoom noj, tshuaj, thiab cov khoom siv niaj hnub. LDPE cov yeeb yaj kiab kuj muaj cov khoom siv hluav taws xob zoo thiab feem ntau siv los ua cov txheej txheem cua sov hauv cov yeeb yaj kiab sib xyaw. Txawm li cas los xij, lawv muaj cov cua sov tsis zoo thiab tsis haum rau cov khoom ntim khoom noj uas kub kub.

2. High-Density Polyethylene Zaj duab xis (HDPE)

HDPE films yog ib qho nyuaj, semi-translucent, thiab xim dawb. Lawv muaj lub zog tensile zoo dua, dej tsis kam, tiv thaiv tshav kub, thiab roj tsis kam piv rau LDPE. HDPE yog tsim rau kev ntim khoom ruaj khov thiab muaj cov yeeb yaj kiab, tab sis muaj qis dua pob tshab thiab gloss.

3. Linear Low-density Polyethylene Film (LLDPE)

LLDPE zaj duab xis muab qhov yooj yim ntawm LDPE nrog lub zog ntawm HDPE, muab cov khoom zoo heev stretching thiab puncture resistance. Lawv tau siv dav hauv cov yeeb yaj kiab stretch, shrink films, thiab wrapping films, ua rau lawv zoo tagnrho rau high-speed automatic ntim.

4. Metallocene Linear Low-density Polyethylene Film (mLLDPE)

mLLDPE films yog tsim los siv metallocene catalysts thiab muaj kev cuam tshuam ntau zog, tensile yield zog, thiab zoo transparency piv rau cov pa LLDPE. Lawv tso cai rau txo cov yeeb yaj kiab thickness ntau dua 15%, yog li txo cov nqi khoom siv. mLLDPE feem ntau yog siv rau hauv tsev xog paj zaj duab xis, ntim zaj duab xis hnyav, ntim zaj duab xis, thiab cov khoom ntim khoom siab kawg.

Lwm cov yeeb yaj kiab yas

1. Polypropylene (PP) Zaj duab xis: Qhov tseem ceeb rau lawv qhov siab melting point (160-170 ° C), ua rau lawv tsim nyog rau cov ntawv thov kub-sau thiab ntim hauv microwave. PP zaj duab xis muaj cov tshuaj tiv thaiv zoo heev thiab feem ntau yog siv rau kev ntim khoom noj txom ncauj thiab cov khoom siv kho mob kom tsis muaj menyuam.

2. Polyvinyl Chloride (PVC) Zaj duab xis: Muaj nuj nqis rau kev pom meej tshwj xeeb thiab luam tawm tab sis ntsib kev siv tsis zoo vim kev txhawj xeeb ib puag ncig. Cov ntawv thov uas tseem tshuav muaj xws li ntim cov hlwv thiab qee cov yeeb yaj kiab cling5.

3. Polyester (PET) Zaj duab xis: khav theeb siab tensile zog thiab thermal stability, PET films yog indispensable rau saj zawg zog electronics, magnetic tapes, thiab high-barrier zaub mov ntim. Biaxially-oriented PET (BOPET) nthuav qhia tshwj xeeb tshaj yog txhim kho cov cuab yeej thiab cov khoom thaiv.

Tshwj xeeb Polymer Films:

1. Polyamide (Nylon): Exceptional oxygen barrier properties for food preservation

2. Polyvinylidene Chloride (PVDC): Zoo noo noo thiab oxygen barrier kev ua tau zoo

3. Polylactic Acid (PLA): Kev hloov pauv bio-based nrog compostability, txawm hais tias ib txwm txwv los ntawm brittleness - tsis ntev los no kev nce qib tau tsim cov yeeb yaj kiab PLA hloov pauv los ntawm kev sib koom ua ke polyether plasticizers ncaj qha rau hauv cov saw hlau polymer.

Yas zaj duab xis ntau lawm txoj kev

1. Blown Film Extrusion: Cov txheej txheem tseem ceeb rau PE zaj duab xis, qhov twg melted polymer yog extruded los ntawm ib ncig tuag, inflated mus rau hauv ib tug npuas, thiab txias los ua ib lub raj uas yuav flattened rau hauv ob-txheej zaj duab xis. Txoj kev no muab cov khoom sib npaug ntawm cov khoom siv hauv tshuab thiab transverse cov lus qhia.

2. Cam khwb cia zaj duab xis Extrusion: Polymer yaj yog extruded los ntawm ib tug ca tuag mus rau ib tug chilled yob, ua films nrog exceptional clarity thiab uniform thickness. Feem ntau rau PP thiab PET zaj duab xis uas cov khoom siv kho qhov muag tseem ceeb heev.

3. Calendering: Feem ntau yog siv rau PVC zaj duab xis, qhov twg cov polymer compound yog dhau los ntawm ib tug series ntawm rhuab rollers kom ua tiav cov thickness tswj. Calendered films feem ntau muaj qhov zoo tshaj plaws ua tiav tab sis tsis tshua muaj cov cuab yeej siv tshuab thoob plaws qhov dav.

4. Kev daws Casting: Siv rau cov yeeb yaj kiab tshwj xeeb uas qhov sib txawv ntawm qhov tsis sib xws lossis qhov kub hnyiab tau txwv tsis pub yaj ua tiav. Cov polymer yog yaj nyob rau hauv cov kuab tshuaj, cam khwb cia rau ib txoj siv, thiab qhuav los ua zaj duab xis-ntaus rau ib co biodegradable films thiab daim ntaub ntawv membrane.

5. Biaxial Orientation: Zaj duab xis yog stretched nyob rau hauv ob qho tib si lub tshuab thiab transverse cov lus qhia, xws li sequentially (tenter thav duab) los yog ib txhij (cov txheej txheem npuas), ua kom muaj zog, clarity, thiab barrier zog. Biaxially-oriented PP (BOPP) thiab PET (BOPET) zaj duab xis yog cov qauv kev lag luam rau kev ntim khoom zoo.

Kev Tsim Kho Tshiab thiab Kev Tsim Kho Tshiab hauv Cov Zaj Duab Xis

Kev lag luam yas zaj duab xis yog hloov zuj zus mus, nrog rau qhov tseem ceeb ntawm kev ruaj khov, kev ua tau zoo, thiab kev ua haujlwm zoo. Qee qhov tseem ceeb muaj xws li:

1.PFAS-Free Slip Agents:Cov neeg ua haujlwm poob qis uas zam cov tshuaj per- thiab polyfluoroalkyl (PFAS), hais txog ob qho kev xav tau kev ua haujlwm thiab kev txhawj xeeb ib puag ncig.

2. Sustainability Initiatives: Cov tuam txhab xws li Fox Ntim tau ua tiav tshem tawm PFAS los ntawm tag nrho lawv cov kev xaiv ntim tau yooj yim, ua raws cov kev cai dav dav thiab kev lag luam. US FDA tau lees paub kev yeem cog lus tshem tawm PFAS los ntawm kev ntim khoom noj, ua rau txo qis kev noj zaub mov zoo rau PFAS.

Cov kev daws teeb meem tshiab rau PFAS-Dawb ua cov khoom siv yas yeeb yaj kiab los ntawm SILIKE

SILIKE siv txoj hauv kev zoo nrog nws cov khoom siv SILIMER series, muab cov tshiabPFAS-free polymer processing aids (PPAs). Cov khoom lag luam nthuav dav no muaj 100% PFAS dawb PPAs, cov khoom lag luam tsis muaj fluorine PPA, thiab PFAS-dawb, tsis muaj fluorine-dawb PPA masterbatches. Los ntawm kev tshem tawm qhov xav tau rau cov tshuaj fluorine ntxiv, cov khoom no ua rau cov txheej txheem tsim khoom rau LLDPE, LDPE, HDPE, mLLDPE, PP, thiab cov khoom siv yeeb yaj kiab. Lawv ua raws li cov cai tshiab ib puag ncig thaum tseem txhawb kev tsim khoom, txo qis qis qis, thiab txhim kho tag nrho cov khoom zoo. Nrog SILIKE PFAS-dawb PPA coj cov txiaj ntsig khoom kawg, suav nrog: tshem tawm cov pob txha tawg (shark tawv nqaij), txhim kho smoothness, thiab nto zoo.
