Cov yeeb yaj kiab PVC mossiv dav hauv kev ntim khoom, cov ntaub ntawv kho kom zoo nkauj, thiab cov ntawv thov tiv thaiv zaj duab xis, nyiam los ntawm cov chaw tsim khoom rau lawv qhov kev ywj pheej zoo tshaj plaws, kev pom tseeb ntawm qhov muag, thiab kev tsim khoom ntau yam uas tsis kim. Txawm tias muaj cov txheej txheem ua haujlwm raws li tus qauv, ntau lub Hoobkas tawm tsam nrog cov qhov tsis zoo rov tshwm sim thaum lub sijhawm tsim khoom thiab kev khaws cia mus sij hawm ntev, suav nrog qhov chaw pos huab, cov hmoov dawb los nag, thiab qhov chaw nplaum tas mus li. Cov teeb meem me me tab sis teeb meem no ua rau zaj duab xis pob tshab thiab qhov chaw du, feem ntau ua rau cov khoom zoo tsis sib xws, cov neeg siv khoom tsis txaus siab, thiab cov khib nyiab tsim khoom tsis tsim nyog.
Feem ntau cov kws tshaj lij tsim khoom feem ntau hais tias qhov ua tsis tiav no yog vim cov plasticizers tsis zoo lossis qhov kub tsis zoo. Txawm li cas los xij, kev rov ua dua qhov kev daws teeb meem ntawm cov mis thiab kev lees paub hauv kev lag luam lees paub tias qhov tsis sib xws ntawm cov stabilizers ib txwm muaj thiab cov tshuab plasticizer yog qhov ua rau muaj qhov teeb meem no. Txawm tias muaj cov plasticizers qib siab thiab cov txheej txheem ua tiav, cov stabilizers tsis sib xws ua rau muaj kev sib cais theem tas mus li thiab kev hloov pauv ntxiv.
Vim li cas nag thiab pos huab tshwm sim rau ntawm cov yeeb yaj kiab PVC mos
Tsis zoo li cov khoom PVC tawv, cov yeeb yaj kiab PVC pob tshab mos mos vam khom cov kua yas ua kom muaj zog kom ua tiav cov qauv yooj ywm thiab lub teeb ci ntsa iab zoo heev. Txhawm rau kom muaj kev ua haujlwm ruaj khov mus sij hawm ntev, tag nrho cov txheej txheem mis yuav tsum muaj kev sib xyaw ua ke thiab kev sib xyaw ua ke ntawm cov khoom ntxiv thiab cov ntaub ntawv hauv paus. Cov khoom siv ruaj khov ib txwm muaj thiab cov calcium-zinc stabilizers qhia txog kev yaj molecular qis hauv cov kua yas ua kom muaj zog, ua rau lawv yooj yim tawg thaum sib tov thiab ua tiav.
Thaum lub sijhawm kub siab extrusion thiab calendaring ntau lawm, cov khoom tsis sib xws stabilizer tsis sib haum nrog cov plasticizers, ua rau cov me me tsis ruaj khov raug kaw hauv cov zaj duab xis matrix. Raws sijhawm, lossis nyob rau hauv qhov kub thiab txias thiab av noo hloov pauv, cov khoom ntxiv tsis ruaj khov no maj mam txav mus rau ntawm qhov chaw ntawm zaj duab xis. Cov seem uas tau tsiv mus rau hauv tsim ib txheej pos huab uas txo qhov pom tseeb, cov hmoov dawb uas ua rau puas tsuaj rau qhov chaw, thiab cov seem nplaum uas cuam tshuam cov txheej txheem tom qab ua tiav xws li lamination, luam ntawv, thiab kev sib txuas.
Cov yeeb yaj kiab PVC ntshiab muaj kev cuam tshuam ntau dua rau cov teeb meem sib xws dua li cov xim lossis cov xim matte. Yog tsis muaj cov xim lossis cov txheej txheem matte los zais cov teeb meem me me, txawm tias cov khoom siv ntxiv me ntsis tuaj yeem ua rau pom kev puas tsuaj. Vim li no, kev ua kom zoo dua ntawm cov stabilizer thiab plasticizer compatibility yog ib kauj ruam tseem ceeb los lav qhov tsim nyog, qib siab pob tshab mos PVC zaj duab xis tsim tawm.
Yuav ua li cas Stabilizer Plasticizer Incompatibility ua rau PVC Film Zoo
Ib qho tshuaj PVC mos mos ruaj khov ua haujlwm ua ib qho system sib npaug: cov yas ua kom yooj ywm thiab ductility, thaum cov stabilizers tswj kev puas tsuaj thermal thiab kev laus thaum lub sijhawm ua thiab kev pabcuam lub neej. Cov khoom ruaj khov txheem thiab cov khoom sib xyaw pheej yig tsis muaj kev ua haujlwm molecular txaus thiab kev ua haujlwm dispersion kom phim cov yas ua haujlwm siab, ua rau lub mis sab hauv tsis sib npaug.
Kev hloov me me rau qhov kub thiab txias ntawm cov khoom ua, lub sijhawm do, lossis cov tshuaj plasticizer tsuas yog tuaj yeem npog cov teeb meem ntawm qhov chaw ib ntus xwb. Cov kev hloov kho sab nraud no tsis tuaj yeem tshem tawm qhov kev pheej hmoo ntawm kev sib cais theem tseem ceeb, uas txhais tau tias yuav muaj pos huab thiab nag los dua thaum lub sijhawm khaws cia ntev thiab siv zaum kawg, ua rau cov khoom tsis ruaj khov. Kev hloov cov tshuaj stabilizer khoom tsis sib xws nrog cov tshuab stabilizer kua uas sib xws yog tib txoj hauv kev txhim khu kev qha los xauv cov mis kom ruaj khov thiab zam kev ua tsis zoo rov qab.
Cov Khoom Siv BaZn thiab KZn Stabilizers: Cov Kev daws teeb meem zoo tshaj plaws rau Cov Yeeb Yaj Kiab PVC Ntshiab
Kev tshaj lijkua BaZn (barium zinc)thiabCov tshuaj stabilizers KZn (potassium zinc)yog tsim tshwj xeeb rau kev tsim cov yeeb yaj kiab PVC mos mos uas muaj pob tshab, daws tau qhov teeb meem ntawm cov khoom ruaj khov ib txwm muaj. Muaj cov kua dej zoo dua thiab kev sib kis ntawm cov molecular, cov nocov tshuaj stabilizerssib tov sib npaug nrog txhua hom plasticizer hauv lub voj voog sib tov luv luv, tsim cov qauv mis ruaj khov, homogeneous nrog xoom kev sib cais tsis sib xws.
Hauv cov xwm txheej tsim khoom loj tiag tiag, cov kua BaZn thiab KZn stabilizers muab peb qhov zoo sib txawv rau kev tsim cov yeeb yaj kiab PVC ntshiab. Ua ntej, lawv tiv thaiv tag nrho cov theem sib cais thiab kev hloov pauv ntxiv, tiv thaiv kom tsis txhob muaj huab cua thiab cov dej nag dawb thaum tseem khaws cia lub teeb ci ntsa iab mus sij hawm ntev. Qhov thib ob, lawv qhov kev sib xyaw zoo heev hloov kho kom haum rau cov kab extrusion ceev thiab cov kab calendaring, ua kom muaj qhov zoo sib xws thoob plaws txhua qhov ntau lawm yam tsis muaj qhov tsis sib npaug ntawm cov mis. Qhov thib peb, kev ruaj khov thermal tiv thaiv kev rhuav tshem ntxiv hauv qab qhov kub siab, tshem tawm cov seem nplaum thiab cov teeb meem daj thaum txhim kho qhov tiaj tiaj ntawm zaj duab xis thiab kev ua tau zoo.
Cov chaw tsim khoom uas muaj teeb meem nrog cov yeeb yaj kiab tsis zoo feem ntau tuaj yeem hloov kho lawv cov mis nrog kev nqis peev tsawg. Hloov mus rau cov kua BaZn lossis KZn stabilizers tsis tas yuav kho dua tshiab ntawm cov kab ntau lawm. Tsuas yog hloov cov khoom qub stabilizer thiab kho qhov sib piv ntawm cov mis tuaj yeem txhim kho cov nqi tsim khoom sai sai, txo cov khoom pov tseg thiab kev pheej hmoo zoo tom qab muag.
Cov Kev Kho Kom Zoo thiab Cov Kev Tiv Thaiv rau Kev Tsim Khoom Ruaj Khoov
Raws li ntau xyoo ntawm kev kho qhov yuam kev hauv cov mis thiab kev txhim kho kev tsim khoom, kev txhim kho kev ua haujlwm tsom mus rau qhov ua tau zoo tuaj yeem ua rau cov mis ruaj khov ntxiv thiab tiv thaiv kom tsis txhob muaj qhov tsis zoo rov tshwm sim. Ua ntej, txhim kho koj lub tshuab ntxiv tag nrho los ntawm kev tshem tawm cov khoom ruaj khov uas tsis sib xws thiab siv cov kua BaZn lossis KZn stabilizers uas muaj cov zaj duab xis pob tshab los tsim kom muaj lub hauv paus mis ruaj khov, tiv taus kev hloov pauv.
Qhov thib ob, ua kom cov khoom siv raw khoom noj thiab cov txheej txheem sib xyaw zoo dua. Ua ntej sib tov cov kua stabilizers kom huv si nrog cov plasticizers ua ntej ntxiv cov hmoov ntxiv, kom ntseeg tau tias muaj kev sib xyaw ua ke tag nrho thiab zam kev sib txawv ntawm cov concentration hauv zos uas ua rau qeeb qeeb. Qhov thib peb, ua kom cov khoom tiav lawm ib puag ncig nrog qhov kub thiab txias tas li kom txo qhov kev sib cais ntawm cov khoom ntxiv. Thaum kawg, kho koj cov mis sib piv kawg thiab zam kev hloov cov khoom ntxiv ntau zaus kom tswj tau qhov zoo ntawm pawg-rau-pawg.
Cov Lus Nug Feem Ntau
Q1: Dab tsi yog qhov ua rau muaj pos huab thiab dawb nag ntawm cov yeeb yaj kiab PVC mos?
A1: Qhov ua rau tseem ceeb yog qhov tsis sib xyaw thiab tsis sib haum ntawm cov khoom ruaj khov thiab cov yas yas.
