Titanate Coupling Agent rau PVC

Cov qauv molecular ntawm titanium ester coupling cov neeg ua haujlwm muaj cov khoom siv tshuaj lom neeg tshwj xeeb: titanium ester ua haujlwm pab pawg ntawm ib kawg tuaj yeem tsim cov tshuaj lom neeg ruaj khov nrog cov pab pawg nquag nyob rau saum npoo ntawm inorganic fillers xws li calcium carbonate thiab talc hmoov; Cov pab pawg ua haujlwm organic ntawm lwm qhov kawg muaj kev sib raug zoo nrog cov saw hlau molecular ntawm PVC cob. Qhov tsim tshwj xeeb molecular no tsim kom muaj kev sib txuas ntawm cov tshuaj inorganic thiab PVC matrix.

Hauv cov txheej txheem tsim khoom ntawm PVC cov khoom, titanate coupling cov neeg ua haujlwm ua lub luag haujlwm los ntawm peb lub tswv yim tseem ceeb:

1. Txhim kho qhov zoo ntawm cov khoom ntawm cov khoom

 

Nyob rau hauv PVC formulations, untreated fillers feem ntau dhau los ua cov ntsiab lus kev ntxhov siab. Titanium ester coupling cov neeg ua haujlwm txhim kho kev sib txuas ntawm kev sib txuas, hloov cov khoom siv los ntawm "kev sib txuas tsis muaj zog" mus rau "lub zog ua kom muaj zog". Cov ntaub ntawv siv tswv yim qhia tau hais tias PVC cov khoom kho nrog titanium ester coupling cov neeg ua haujlwm tuaj yeem ua rau lawv lub zog tensile los ntawm 25% -40%, cuam tshuam lub zog los ntawm 30% -50%, thiab khoov lub zog los ntawm 20% -35%, txhim kho cov kav ntev thiab kev ntseeg siab ntawm cov yeeb nkab, thiab lwm yam khoom.

2. Optimize kev ua tau zoo thiab ntau lawm efficiency

 

PVC ua yuav tsum muaj rheological zog ntawm cov yaj. Tom qab txhim kho lub xeev dispersion ntawm fillers nrog titanium ester coupling cov neeg ua haujlwm, kev ua haujlwm tau zoo tuaj. Tshwj xeeb, lub siab extrusion raug txo los ntawm 15% -25%, ua rau txo qis hauv kev siv zog; Kev ruaj ntseg ntawm cov khoom molding tau raug txhim kho, thiab qhov zoo ntawm qhov chaw tau zoo dua; Ntau lawm efficiency nce 18% -30%, tshwj xeeb tshaj yog haum rau high-speed extrusion thiab txhaj tshuaj molding txheej txheem.

3. Ua tau zoo filling thiab economic optimization

 

Titanium ester coupling cov neeg ua haujlwm tsim cov xwm txheej rau kev faib ua feem ntau los ntawm kev txhim kho interfacial compatibility. Kev lag luam kev coj ua tau pom tias qhov zoo tshaj qhov sib ntxiv ntawm titanium ester coupling tus neeg sawv cev rau PVC yog tswj ntawm 5% -10% ntom, uas tuaj yeem ua rau muaj kev nyab xeeb ntxiv cov khoom ntxiv xws li calcium carbonate mus rau 40% -60%, thaum tswj cov khoom ua tau zoo thiab ua tiav kev txo qis ntawm cov nqi raw khoom los ntawm 25% -40%.

Raws li cov chaw tsim khoom loj ntawm cov neeg ua haujlwm sib txuas, Shandong Chunqian New Materials Co., Ltd. tso siab rau cov ntawv pov thawj muaj txiaj ntsig zoo thiab ntau xyoo ntawm kev tsim khoom thiab kev muag khoom los muab cov khoom lag luam txhawb nqa thiab kev pabcuam rau kev lag luam PVC.

Thaum ib lub tuam txhab PVC profile ntau lawm yog siv cov calcium carbonate zoo tib yam, nws tau ntsib teeb meem xws li cov khoom tsis txaus thiab qhov ntxhib nto. Tom qab qhia cov titanium ester coupling tus neeg sawv cev muab los ntawm Chunqian Cov Khoom Tshiab (nrog rau qhov sib ntxiv ntawm 8% ntawm cov muab tub lim), cov nyiaj calcium carbonate ntxiv tau nce los ntawm 35% mus rau 50%. Nyob rau tib lub sijhawm, qhov cuam tshuam lub zog ntawm cov khoom tau nce los ntawm 45%, lub zog tensile nce los ntawm 32%, lub ntsej muag glossiness tau nce los ntawm 40%, cov nqi sib tw tau txo los ntawm 30%, thiab kev lag luam kev sib tw ntawm cov khoom tau txhim kho.

Daim ntawv thov ntawm titanium ester coupling tus neeg sawv cev hauv kev lag luam PVC npog ntau qhov chaw:

Nrog rau kev txhim kho ntawm PVC kev lag luam mus rau kev ua tau zoo thiab kev tiv thaiv ib puag ncig, daim ntawv thov kev cia siab ntawm titanium ester coupling cov neeg ua haujlwm nyob rau hauv cov chaw tawm tshiab xws li lead-cov tshuab tsis pub dawb thiab cov tshuab yas zoo ib puag ncig yog dav.

Xaiv cov qauv sib txuas tsim nyog raws li cov khoom siv PVC; Txiav txim siab qhov txiaj ntsig zoo ntxiv los ntawm kev sim thiab ua kom zoo dua li ntawm 5% -10%; nruj me ntsis tswj cov txheej txheem kub thiab sib tov lub sij hawm; Ua tib zoo saib xyuas kev sib raug zoo nrog stabilizers, lubricants, thiab lwm yam additives; Tsim kom muaj kev tswj xyuas zoo kom paub meej cov khoom ruaj khov.

Titanium ester coupling cov neeg ua haujlwm tau ua lub luag haujlwm tseem ceeb hauv kev lag luam PVC los ntawm lawv cov cuab yeej hloov kho zoo heev. Nws tsis tsuas yog ua tau zoo daws cov teeb meem kev ua haujlwm los ntawm kev ua haujlwm siab, tab sis kuj muab cov tswv yim thiab cov kev daws teeb meem rau kev lag luam kom ua tiav cov nqi txo thiab txhim kho kev ua haujlwm. Raws li cov kws tshaj lij kev tsim khoom, Shandong Chunqian New Materials Co., Ltd. tau dhau los ua tus khub tseem ceeb rau PVC kev lag luam thev naus laus zis kho dua tshiab thiab cov khoom lag luam tshiab, tso siab rau qhov zoo ntawm - cov khoom lag luam zoo thiab pheej yig, kev cia khoom txaus txaus lav, lav tom qab - kev cog lus kev muag khoom, thiab kev lees paub zoo, ua ke nrog ntau xyoo ntawm kev tsim khoom thiab kev muag khoom. Nrog kev nce qib ntawm cov khoom siv thev naus laus zis tas li, titanium ester coupling cov neeg ua haujlwm yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa siab - kev txhim kho zoo ntawm PVC kev lag luam.
