Thaum koj qhwv cov khoom noj tshiab lossis cov khoom seem nrog PVC cling film, tej zaum koj yuav tsis xav txog cov tshuaj lom neeg nyuaj uas ua rau daim ntawv yas nyias nyias ntawd yoog tau, pob tshab, thiab muaj kev nyab xeeb rau kev sib cuag nrog zaub mov. Txawm li cas los xij tom qab txhua lub yob ntawm cov yeeb yaj kiab PVC zoo yog ib qho tseem ceeb: tusPVC stabilizerCov tshuaj ntxiv no ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev puas tsuaj, ua kom muaj kev nyab xeeb, thiab tswj kev ua haujlwm - ua rau lawv tseem ceeb rau cov ntawv thov ntim khoom noj.
Vim li cas PVC Cling Films xav tau cov Stabilizers tshwj xeeb
PVC tsis ruaj khov thaum raug cua sov, lub teeb, thiab kev ntxhov siab thaum lub sijhawm ua thiab siv kawg. Yog tsis muaj kev ruaj khov kom zoo, PVC yuav lwj, tso cov kua qaub hydrochloric tawm thiab ua rau cov khoom siv tawg, tsis muaj xim, thiab tsis zoo rau kev sib cuag nrog zaub mov.
Rau cov yeeb yaj kiab cling tshwj xeeb, cov teeb meem yog qhov tshwj xeeb:
• Lawv xav tau kev pom tseeb tshwj xeeb los qhia cov khoom noj khoom haus
• Yuav tsum tswj tau qhov yooj ywm ntawm ntau qhov kub thiab txias
• Yuav tsum tiv taus kev puas tsuaj thaum lub sijhawm ua haujlwm kub siab
• Yuav tsum ua raws li cov cai tswjfwm kev nyab xeeb zaub mov nruj heev
• Yuav tsum tau ruaj khov mus sij hawm ntev thaum lub sij hawm khaws cia thiab siv
Cov Kev Cai Tseem Ceeb rau Cov Khoom Noj Khoom Haus PVC Stabilizers
Tsis yog txhua yam PVC stabilizers tsim nyog rau kev siv rau hauv kev sib cuag zaub mov. Cov stabilizers zoo tshaj plaws rau PVC cling films yuav tsum ua tau raws li cov qauv nruj:
Kev Ua Raws Cai
Cov khoom siv PVC stabilizers uas yog qib zaub mov yuav tsum ua raws li cov cai nruj thoob ntiaj teb. Hauv Tebchaws Meskas, FDA's 21 CFR Part 177 tswj cov khoom siv yas hauv kev sib cuag zaub mov, txwv cov khoom ntxiv xws li phthalates kom tsis pub ntau tshaj 0.1% hauv cov khoom PVC. Cov cai European (EU 10/2011) zoo sib xws txwv cov tshuaj lom neeg thiab teeb tsa cov kev txwv kev tsiv teb tsaws chaw kom ntseeg tau tias cov neeg siv khoom muaj kev nyab xeeb.
Cov Qauv Tsis Muaj Tshuaj Lom
Cov tshuaj stabilizers uas siv cov hlau txhuas ib txwm muaj, uas ib zaug siv tau rau hauv kev ua PVC, tau raug tshem tawm ntau zaus hauv kev siv zaub mov vim muaj kev txhawj xeeb txog kev lom.cov khoom noj khoom haus stabilizerszam cov hlau hnyav kiag li, tsom mus rau lwm txoj hauv kev nyab xeeb dua.
Kev Ruaj Ntseg Thermal
Kev tsim cov yeeb yaj kiab lo yuav tsum muaj cov txheej txheem extrusion thiab calendering kub siab uas tuaj yeem ua rau PVC puas tsuaj. Cov tshuaj stabilizer zoo yuav tsum muab kev tiv thaiv kub zoo thaum lub sijhawm tsim khoom thaum tswj hwm qhov zoo ntawm cov yeeb yaj kiab.
Kev Tswj Xyuas Kom Pom Tseeb
Tsis zoo li ntau yam khoom PVC, cov yeeb yaj kiab cling xav tau qhov pom tseeb tshwj xeeb. Cov stabilizers zoo tshaj plaws tawg sib npaug yam tsis tsim cov pos huab lossis cuam tshuam rau cov khoom siv pom kev.
Kev Sib Tw Nrog Lwm Cov Khoom Ntxiv
Cov stabilizers yuav tsum ua haujlwm sib haum xeeb nrog cov plasticizers, cov roj nplua nyeem, thiab lwm yam khoom ntxiv hauv cov qauv cling film kom tswj tau qhov kev ua tau zoo tag nrho.
Cov Kev Xaiv Stabilizer Sab Saum Toj rau PVC Cling Films
Txawm hais tias muaj ntau yam tshuaj stabilizer chemistry, ob hom tau tshwm sim ua cov kev xaiv tseem ceeb rau cov yeeb yaj kiab cling zaub mov:
Cov Khoom Siv Kho Kom Zoo Calcium-Zinc (Ca-Zn)
Cov tshuaj stabilizers Calcium-zinctau dhau los ua tus qauv kub rau kev siv PVC rau zaub mov. Cov tshuaj ntxiv no tsis muaj tshuaj lom, tsis ua rau ib puag ncig puas tsuaj muab kev sib npaug zoo ntawm kev ua tau zoo thiab kev nyab xeeb:
Calcium zinc stabilizer yog ib qho kev xaiv tsis muaj tshuaj lom uas tsis muaj cov hlau phom sij thiab lwm yam tshuaj lom neeg, ua rau nws yog ib hom tshiab ntawm cov khoom siv tiv thaiv ib puag ncig rau PVC.
Cov txiaj ntsig tseem ceeb suav nrog:
• Kev ruaj khov zoo heev thaum lub sijhawm ua haujlwm
• Zoo rau huab cua thiab tiv taus daj
• Kev ua kom lubrication zoo uas ua rau extrusion ceev dua
• Kev sib raug zoo nrog PVC resin thiab lwm yam khoom ntxiv
• Ua raws li cov cai tseem ceeb ntawm kev sib cuag nrog cov khoom noj
• Muaj peev xwm ua kom pom tseeb hauv cov yeeb yaj kiab nyias
Cov Khoom Siv UV Stabilizers rau Kev Tiv Thaiv Ntev
Txawm hais tias tsis yog cov tshuaj tiv thaiv kub tseem ceeb, cov khoom nqus UV ua lub luag haujlwm tseem ceeb hauv kev khaws cia thiab siv cov yas nplaum. Cov tshuaj ntxiv no muaj txiaj ntsig zoo rau cov yas nplaum uas siv rau hauv cov pob tshab uas raug lub teeb.
Yuav Ua Li Cas Xaiv Qhov Stabilizer Zoo Rau Koj Daim Ntawv Thov Cling Film
Kev xaiv qhov zoo tshaj plaws stabilizer yuav tsum tau sib npaug ntau yam:
• Kev Ua Raws Cai:Xyuas kom meej tias ua raws li cov qauv kev nyab xeeb zaub mov hauv cheeb tsam (FDA, EU 10/2011, thiab lwm yam) rau koj cov neeg yuav khoom.
• Cov Kev Cai Ua Haujlwm:Xav txog koj cov xwm txheej tsim khoom tshwj xeeb - cov txheej txheem kub dua yuav xav tau kev ruaj khov thermal zoo dua.
• Kev Xav Tau Kev Ua Tau Zoo:Tshuaj xyuas cov kev xav tau ntawm kev meej, kev xav tau kev ywj pheej, thiab lub sijhawm cia khoom rau koj cov khoom siv cling film.
• Kev Sib Haum Xeeb:Xyuas kom tseeb tias lub stabilizer ua haujlwm zoo nrog koj cov plasticizers thiab lwm yam additives.
• Kev Ruaj Ntseg:Nrhiav cov stabilizers uas txhawb nqa cov hom phiaj ib puag ncig los ntawm kev lom tsawg thiab txo qhov cuam tshuam rau ib puag ncig.
• Kev Siv Nyiaj Zoo:Sib npaug cov txiaj ntsig ntawm kev ua tau zoo piv rau cov nqi tsim khoom, xav txog ob qho tib si kev sib xyaw ua ke thiab kev ua haujlwm tau zoo.
Yav Tom Ntej ntawm PVC Stabilizers hauv Kev Ntim Khoom Noj
Raws li cov neeg siv khoom xav tau kev nyab xeeb thiab ua tau zoo ntawm cov khoom noj khoom haus txuas ntxiv mus, cov thev naus laus zis PVC stabilizer yuav hloov pauv kom tau raws li cov teeb meem tshiab. Peb tuaj yeem cia siab tias yuav pom:
• Kev txhim kho ntxiv hauv kev ruaj khov thermal ntawm cov khoom xyaw ntxiv qis dua
• Cov tshuaj zoo dua uas txhawb nqa kev siv dua tshiab thiab lub hom phiaj kev lag luam ncig
• Cov khoom sib xyaw ua kom ruaj khov tshiab uas tau tsim tshwj xeeb rau cov ntawv thov tshwj xeeb ntawm cov yeeb yaj kiab nplaum
• Cov txheej txheem sim siab heev kom ntseeg tau tias muaj kev nyab xeeb thiab kev ua tau zoo
• Kev hloov pauv ntawm txoj cai lij choj txuas ntxiv tsav kev tsim kho tshiab hauv cov kev xaiv tsis muaj tshuaj lom
Cov kev tsim kho tshiab hauv kev tshawb fawb txog cov ntaub ntawv tau qhib lub peev xwm tshiab rau PVC stabilizers, nrog rau kev tshawb fawb tsom mus rau kev tsim cov kev daws teeb meem zoo dua thiab ruaj khov rau cov ntawv thov ntim khoom noj.
Kev Nqis Peev rau Cov Khoom Siv Zoo rau Cov Yeeb Yam Cling Zoo Tshaj Plaws
Cov PVC stabilizer zoo yog qhov tseem ceeb rau kev tsim cov yeeb yaj kiab zoo, muaj kev nyab xeeb, thiab ua raws li txoj cai rau kev ntim khoom noj. Txawm hais tias cov calcium-zinc stabilizers tam sim no ua tus thawj coj hauv kev lag luam rau lawv qhov kev sib npaug zoo ntawm kev nyab xeeb thiab kev ua tau zoo, kev tsim kho tshiab tas mus li cog lus tias yuav muaj kev daws teeb meem zoo dua yav tom ntej.
Los ntawm kev muab qhov tseem ceeb rau kev ua raws li txoj cai, cov yam ntxwv ntawm kev ua tau zoo, thiab kev txiav txim siab ib puag ncig, cov tuam ntxhab tsim khoom tuaj yeem xaiv cov stabilizers uas tsis yog tsuas yog ua tau raws li cov kev xav tau tam sim no tab sis tso lawv cov khoom rau kev vam meej yav tom ntej hauv kev lag luam uas hloov pauv sai.
Raws li kev lag luam PVC stabilizer txuas ntxiv nws txoj kev loj hlob ruaj khov, qhov tseem ceeb ntawm cov khoom siv tseem ceeb no hauv kev ua kom muaj kev nyab xeeb thiab kev ua tau zoo ntawm cov yeeb yaj kiab cling-grade zaub mov tsuas yog yuav nce ntxiv xwb - ua rau kev xaiv cov stabilizer paub ntau dua li yav dhau los.
