PVC tseem yog ib tus neeg ua haujlwm hauv kev tsim khoom, tab sis nws lub pob taws ntawm Achilles - thermal degradation thaum ua haujlwm - tau ua rau cov neeg tsim khoom ntev. Nkag musCov kua kalium zinc PVC stabilizers: ib qho kev daws teeb meem uas daws cov teeb meem nyuaj tshaj plaws thaum txhim kho kev tsim khoom. Cia peb tawg ua li cas qhov no additive transforms PVC manufacturing ..
Nres Thermal Breakdown hauv Nws Txoj Kev
PVC pib degrade ntawm qhov kub thiab txias li 160 ° C, tso cov pa phem HCl thiab tig cov khoom nkig los yog tsis muaj xim. Cov kua kalium zinc stabilizers ua raws li kev tiv thaiv tiv thaiv, ncua kev degradation los ntawm neutralizing HCl thiab tsim cov complexes ruaj khov nrog cov saw hlau polymer. Tsis zoo li ib leeg-hlau stabilizers uas fizzle tawm sai sai, kalium-zinc combo muab kev tiv thaiv txuas ntxiv-ua kom PVC ruaj khov txawm tias lub sijhawm ntev extrusion khiav ntawm 180-200 ° C. Qhov no txhais tau hais tias tsawg dua cov khoom tsis lees paub vim yog daj lossis tawg, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv nyias nyias xws li cov yeeb yaj kiab thiab cov ntawv txheeb.
Tshem tawm cov txheej txheem ntawm lub raj mis
Cov neeg tsim khoom paub qhov kev ntxhov siab ntawm kev kaw cov kab ntau zaus. Traditional stabilizers feem ntau tso cov seem ntawm cov tuag thiab cov ntsia hlau, yuam kom nres rau kev tu txhua 2-3 teev. Cov kua dej kalium zinc cov qauv, txawm li cas los xij, muaj cov viscosity tsawg uas ntws zoo los ntawm cov khoom siv, txo qis kev tsim. Ib lub chaw tsim khoom siv yeeb nkab tau tshaj tawm txiav lub sijhawm tu los ntawm 70% tom qab hloov pauv, nce cov zis txhua hnub los ntawm 25%. Daim ntawv ua kua kuj sib tov sib npaug nrog PVC resin, tshem tawm clumping uas ua rau tsis sib xws hauv cov profiles lossis cov kav dej.
Boosts Durability hauv cov khoom kawg
Nws tsis yog hais txog kev tsim khoom-kev siv kawg nkaus tseem ceeb heev. PVC cov khoom kho nrogkalium zinc stabilizersqhia kev txhim kho tiv thaiv UV rays thiab ya raws, txuas ntxiv lifespans nyob rau hauv sab nraum zoov daim ntaub ntawv xws li qhov rais thav duab los yog vaj hoses. Hauv cov khoom lag luam hloov pauv xws li gaskets lossis kev kho mob tubing, lub stabilizer tuav elasticity thaum lub sij hawm, tiv thaiv cov tawv nqaij uas ua rau kom tawg lossis ua tsis tiav. Kev ntsuam xyuas qhia tau hais tias cov khoom no khaws 90% ntawm lawv lub zog tensile tom qab 500 teev ntawm kev laus zuj zus, ua tau zoo dua cov uas tau ua nrog cov pa ntxiv.
Ua tau raws li cov qauv kev nyab xeeb nruj
Kev tswj hwm lub siab yog mounting rau kev nyab xeeb PVC additives, tshwj xeeb tshaj yog nyob rau hauv cov zaub mov-kev sib cuag los yog kev kho mob-qib khoom. Cov kua kalium zinc stabilizers kos tag nrho cov thawv: lawv tsis muaj cov hlau hnyav xws li txhuas lossis cadmium, thiab lawv cov neeg tsiv teb tsaws chaw tsawg ua rau lawv ua raws li FDA thiab EU 10/2011 cov cai. Tsis zoo li qee cov organic stabilizers uas muaj tshuaj lom, cov mis no nyob twj ywm hauv cov polymer matrix - tseem ceeb rau cov ntawv thov xws li ntim khoom noj lossis cov khoom ua si menyuam yaus.
Nqi-zoo yam tsis muaj kev cuam tshuam
Hloov mus rau cov khoom siv ntxiv feem ntau txhais tau tias tus nqi siab dua, tab sis tsis nyob ntawm no. Cov kua kalium zinc stabilizers xav tau 15-20% tsawg dua li cov khoom siv kom ua tiav cov txiaj ntsig zoo ib yam, txiav cov nqi raw khoom. Lawv cov kev ua tau zoo kuj txo qis kev siv hluav taws xob: kev ua haujlwm smoother txo qis extrusion kub los ntawm 5-10 ° C, trimming nqi hluav taws xob. Rau cov tuam txhab me me rau nruab nrab, cov nyiaj khaws cia no ntxiv sai sai - feem ntau recouping tus nqi hloov hauv 3-4 lub hlis.
Cov lus qhia meej: kua kalium zinc stabilizers tsis yog kho PVC cov teeb meem xwb - lawv rov txhais qhov ua tau. Los ntawm kev sib txuas cov kev tiv thaiv thermal, kev ua haujlwm zoo, thiab kev nyab xeeb, lawv tau dhau los ua kev xaiv rau cov neeg tsim khoom uas tsis kam txi zoo rau tus nqi. Hauv kev ua lag luam uas muaj kev ntseeg siab thiab kev ua raws cai tsis yog sib tham, cov khoom ntxiv no tsis yog kev hloov kho xwb - nws yog qhov tsim nyog.
