Taw qhia
Raws li cov khoom siv tseem ceeb hauv kev lag luam ntim niaj hnub, kev ua haujlwm ntawm cov kua nplaum ncaj qha cuam tshuam rau kev ntim khoom thiab kev nyab xeeb ntawm kev thauj mus los. Nrog rau txoj kev loj hlob sai ntawm e-lag luam thiab cov kev xav tau ntawm ib puag ncig, kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ua haujlwm ntawm cov kua nplaum. Lub hom phiaj ntawm txoj kev tshawb no yog txhawm rau txhim kho kev ua tau zoo ntawm cov sealants los ntawm kev ua kom zoo ntawm cov khoom sib xyaw thiab cov txheej txheem tsim cov sealants kom tau raws li kev xav tau ntawm kev lag luam.
Nyob rau hauv xyoo tas los no, cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau tshawb fawb ntau txog kev ntim cov kua nplaum. Smith et al. tau kawm txog cov teebmeem ntawm cov nplaum sib txawv ntawm kev ua haujlwm ntawm cov sealants, thaum Zhang pab pawg tau tsom mus rau kev txhim kho cov khoom zoo ib puag ncig. Txawm li cas los xij, kev tshawb fawb txog kev ua kom zoo tshaj plaws ntawm sealant kev ua haujlwm tseem tsis txaus. Kab lus no yuav pib los ntawm kev xaiv cov ntaub ntawv, kev tsim kho kom zoo thiab txhim kho cov txheej txheem tsim khoom, thiab tshawb xyuas cov txheej txheem los txhim kho kev ua haujlwm ntawm cov kua nplaum.
I. Muaj pes tsawg leeg thiab cov yam ntxwv ntawmpacking kua nplaum
Lub sealant feem ntau muaj peb ntu: nplaum, substrate thiab additive. Adhesives yog cov khoom xyaw tseem ceeb uas txiav txim siab cov khoom ntawm sealants, thiab lawv feem ntau pom muaj nyob rau hauv acrylic, roj hmab thiab silicone. Lub substrate feem ntau yog polypropylene zaj duab xis lossis ntawv, thiab nws cov thickness thiab kev kho deg yuav cuam tshuam rau cov khoom siv ntawm daim kab xev. Cov additives muaj xws li plasticizers, fillers thiab antioxidants los txhim kho cov khoom tshwj xeeb ntawm daim kab xev.
Cov khoom ntawm sealant feem ntau suav nrog adhesion, pib adhesion, tuav adhesion, tsis kam rau ntuj huab cua thiab kev tiv thaiv ib puag ncig. Lub zog ntawm daim ntawv cog lus txiav txim siab lub zog sib khi ntawm daim kab xev thiab cov nplaum, thiab yog ib qho tseem ceeb qhia txog kev ua haujlwm ntawm sealant. Thawj viscosity cuam tshuam rau qhov pib adhesion muaj peev xwm ntawm daim kab xev, thaum lub viscosity ntawm daim kab xev qhia txog nws lub sijhawm ntev. Kev tiv thaiv rau ntuj huab cua muaj xws li kub tsis kam, tsis kub tsis kam thiab noo noo tsis kam. Kev tiv thaiv ib puag ncig tsom rau cov khoom degradable thiab tsis muaj tshuaj lom ntawm cov kab xev, uas ua tau raws li kev tsim kho kom ruaj khov ntawm cov khoom ntim niaj hnub.
II. Daim ntawv thov ntawm sealants
Sealants yog dav siv nyob rau hauv ntim hauv ntau yam lag luam. Hauv kev xa khoom, cov sealants muaj zog yog siv los tiv thaiv cov thawv hnyav thiab ua kom muaj kev nyab xeeb ntawm cov khoom hauv kev thauj mus los ntev. E-lag luam ntim khoom xav kom cov sealants muaj qhov zoo pib viscosity thiab tuav adhesion los tiv nrog nquag sorting thiab tuav. Hauv kev ntim khoom noj, nws yog ib qho tsim nyog yuav tsum tau siv cov khoom zoo ib puag ncig los ua kom cov zaub mov muaj kev nyab xeeb thiab kev nyiam huv.
Hauv qhov chaw tshwj xeeb, kev siv cov sealants yog qhov nyuaj dua. Piv txwv li, nyob rau hauv txias saw logistics, packing kua nplaum yuav tsum tau zoo heev kub kuj; Nyob rau hauv qhov kub thiab av noo nyob ib puag ncig, daim kab xev yuav tsum muaj qhov zoo thermal kuj. Tsis tas li ntawd, qee qhov kev lag luam tshwj xeeb xws li cov khoom siv hluav taws xob thiab cov chaw muag tshuaj muab cov kev xav tau siab dua ntawm kev tiv thaiv electrostatic thiab cov kab mob tua kab mob ntawm cov sealants. Cov ntawv thov sib txawv no xav tau tsav lub nruam tshiab thiab kev txhim kho ntawm sealant technology.
III. Kev tshawb fawb txog kev ua kom zoo ntawm sealant kev ua tau zoo
Txhawm rau txhim kho kev ua tau zoo ntawm cov sealants, txoj kev tshawb no saib peb yam ntawm kev xaiv cov khoom siv, kev tsim kho kom zoo thiab cov txheej txheem tsim khoom. Hauv kev xaiv cov nplaum, cov khoom ntawm peb cov ntaub ntawv, acrylic, roj hmab thiab silicone, tau muab piv, thiab acrylic muaj qhov zoo ntawm cov khoom zoo. Qhov kev ua tau zoo ntawm acrylic nplaum tau ntxiv optimized los ntawm kev kho cov monomer feem thiab molecular hnyav.
Lub optimization ntawm substrates tsom tsuas yog nyob rau hauv thickness thiab nto kho.Qhov kev sim qhia tau hais tias 38μm tuab biaxially oriented polypropylene zaj duab xis ua tiav qhov zoo tshaj plaws sib npaug ntawm lub zog thiab tus nqi.Qhov electrode kev kho deg ho txhim kho lub zog saum npoo ntawm substrate thiab txhim kho lub zog sib txuas nrog cov nplaum. Natural plasticizers tau siv los hloov cov khoom siv roj av ib txwm siv, thiab nano-SiO2 tau ntxiv los txhim kho kev tiv thaiv cua sov.
Kev txhim kho hauv cov txheej txheem ntau lawm suav nrog kev ua kom zoo ntawm cov txheej txheem txheej txheej thiab kev tswj cov txheej txheem kho.Siv micro-gravure txheej tshuab, cov txheej txheej ntawm cov nplaum yog pom tau, thiab cov tuab yog tswj ntawm 20 ± 2 μm.Studies ntawm qhov kub thiab lub sij hawm ntawm curing tau pom tias curing ntawm 80 ° C rau 3 feeb ntawm kev ua haujlwm zoo tshaj plaws. nplaum lub zog ntawm lub sealant tau nce los ntawm 30%, kev tiv thaiv rau ntuj huab cua tau txhim kho, thiab VOC emission raug txo los ntawm 50%.
IV. Cov lus xaus
Txoj kev tshawb no tau txhim kho nws txoj kev ua tau zoo los ntawm kev ua kom zoo ntawm cov khoom sib xyaw thiab cov txheej txheem tsim khoom ntawm sealant. Lub optimized sealant tau mus txog kev lag luam ua theem nyob rau hauv cov nqe lus ntawm adhesion, tsis kam mus rau ntuj huab cua thiab kev tiv thaiv ib puag ncig. Cov txiaj ntsig kev tshawb fawb tau muab cov ntsiab lus theoretical thiab cov lus qhia ua tau zoo rau kev txhim kho kev ua haujlwm ntawm cov sealants thiab kev tsim cov khoom tshiab, thiab tseem ceeb heev rau kev txhawb nqa kev lag luam thiab kev loj hlob ntawm kev lag luam ntim. Kev tshawb fawb yav tom ntej tuaj yeem tshawb nrhiav cov ntaub ntawv tshiab rau ib puag ncig thiab cov txheej txheem tsim khoom ntse kom ua tau raws li qhov xav tau kev tiv thaiv ib puag ncig ntxiv thiab kev xav tau ntim tus kheej.
