Kuyimitsidwa polymerization wa hydroxypropyll methylcellulose mu PVC

Kuyimitsidwa polymerization wa hydroxypypyl methylcellulose (hpmc) mu polyvinyl chloride (pvc) si njira yodziwika. HPMC imagwiritsidwa ntchito ngati zowonjezera kapena zosintha mu ma pvc mawonekedwe m'malo mopatsa mphamvu wothandizira wa polymerization.

Komabe, HPMC imatha kukhazikitsidwa mu PVC PRORUS POPANDA ZINSINSI ZOSAVUTA KUTI IZIKHALA NDI PVC Resin ndi zina zowonjezera kapena zowonjezera. Zikatero, hpmc amagwira ntchito zosiyanasiyana monga Thicner, Bander, okhazikika, kapena rheology okhazikika.

Nawa maudindo ena wamba a hpmc mu PVC:

1. Thickener ndi Rhelogy Modisier: HPMC ikhoza kuwonjezeredwa ku PVC ikhoza kuwonjezeredwa ndi ma pvc kuti musinthe ma visction, kusintha mawonekedwe, ndikuwonjezera kayendedwe ka kayendedwe ka polymer kusungunuka pokonza.
2. Conder ndi zotsatsa: hpmc imathandizira pakati pa mapepala a PVC ndi zina zowonjezera popanga, kulimbikitsa homogeneity ndi kukhazikika. Zimathandiza kuti mamangements pamodzi, kuchepetsa kusiyana ndi kukonza magwiridwe antchito a PVC.
3. Chingwe chokhazikika: hpmc chimakhala ngati chiwongola dzanja cha PVC, kupereka kuwonongeka kwa matenthedwe, ma radiation ya UV, ndi oxidation. Zimawonjezeranso kuphatikizika kwa mapira okhala ndi pvc remin, kukonza kusinthasintha, kukhazikika, komanso kusakwanira kwa zinthu za PVC.
4. Zosintha mozizira: M'mapulogalamu ena a PVC, HPMC imatha kukhala ngati yodzisintha, kukonza mphamvu ndi kukana zinthu za PVC. Zimathandizira kukulitsa duckidisic ndi kuwongolera mphamvu ya PVC, kuchepetsa mwayi wa kulephera kwa Brittle.
5. Zosefera ndi zolimbitsa thupi: HPMC itha kugwiritsidwa ntchito ngati cholumikizira kapena chogwirira ntchito mu ma pvc mawonekedwe owonjezera makina, modulus, komanso kukhazikika kwakanthawi. Zimathandizanso kuchita zinthu mogwirizana ndi kukhulupirika kwa PVC.

Pomwe HPMC siili polymered ndi pvc kudzera pakuyimitsidwa polymerization, imadziwitsidwa mu PVC Purceulani pakupanga njira zopangira magwiridwe antchito. Monga chowonjezera kapena chosintha, hpmc limathandizira kuti pazinthu zosiyanasiyana za PVC, zimapangitsa kuti akhale oyenera ntchito zosiyanasiyana m'mafakitale monga ntchito, zoyendetsera zokha, ndizaumoyo, ndi zaumoyo.
