Kukhazikika kwa PVCndi zowonjezera zomwe zimagwiritsidwa ntchito kukonza kukhazikika kwa mafuta a polyvinyl chloride (pvc) ndi popsoli. Kwa mapulaneti a PVC, ngati makonzedwe osinthira amaposa 160 ℃, kuwonongeka kwa mafuta kudzachitika ndipo HCL GOIG idzapangidwa. Ngati sanaponyedwe, kuwonongeka kwa magetsi kumeneku kudzakulilitsidwa, kumapangitsa kuti chitukuko ndi kugwiritsa ntchito mapulaneti a PVC.
Kafukufuku adawona kuti ngati mapulaneti a PVC ili ndi mchere wamchere, sopo wachitsulo, phenol, zodetsa za Armatic, zonyansa zake sizikhudzidwa, komabe, kuwonongeka kwake kumatha kuchepetsedwa pamlingo wina. Maphunzirowa amalimbikitsa kukhazikitsa kukhazikitsidwa ndi kupitiliza kwa okhazikika pa PVC.
Okhazikika PVC Conserm amaphatikiza okhazikika okhazikika, okhazikika mchere wachitsulo, ndi okhazikika amchere. Kukhazikika kwambiri kumagwiritsidwa ntchito kwambiri popanga zinthu za PVC chifukwa cha kuwonekera kwawo, kukana nyengo komanso kulingana. Chibwenzi cha Chitsulo Chitsulo nthawi zambiri chimagwiritsa ntchito calcium, zinc, kapena barium mchere, womwe umatha kupereka bata labwino. Ogwiritsa ntchito mchere monga scrofate sulfate, hibosic lead phosubati, etc. amakhala ndi nthawi yayitali komanso kusokonezeka kwa magetsi. Mukamasankha chibiziro choyenera cha PVC, muyenera kuganizira zomwe zagwiritsidwa ntchito pazinthu za PVC ndi zomwe zimafunikira kukhazikika. Kukhazikika kosiyanasiyana kumakhudzanso magwiridwe antchito a PVC mwakuthupi komanso kupangidwa, kotero kuyesa kokhazikika kumafunikira kuti atsimikizire kuti kukhazikika kwa okhazikika. Kuyamba mwatsatanetsatane komanso kufanizira kwa okhazikika osiyanasiyana PVC kuli motere:
Staterin State:Kukhazikika kwalotin ndi okhazikika kwambiri pazinthu za PVC. Magulu awo ndi omwe amatenga zinthu zopangidwa ndi orlotin oxisin kapena chorlotin chlorides okhala ndi ma asidi oyenera kapena ester.
Okhazikika okhazikika amagawidwa kukhala wopanda sulufuwu komanso sulfure. Kukhazikika kwa Sulfar-okhala ndi okhazikika kumakhala kopambana, koma pali zovuta pakumva kukoma ndi kukhazikika kozungulira ndi mankhwala ena okhala ndi sulufule. Kukhazikika kwa Sulfar Ectin Elotin nthawi zambiri kumatengera malsic acid kapena theka la acid ester. Amakonda zolimbitsa mitu ya methyl zimagwiritsa ntchito zolimbitsa thupi zokhala ndi zokhazikika.
Kukhazikika kwenikweni kumagwiritsidwa ntchito makamaka pazakudya za chakudya ndi zinthu zina za PVC ngati mitengo yowonekera.
Patsani zolimbitsa:Kukhazikika kwa okhazikika kumaphatikizapo mitundu yotsatirayi: Dibosic kutsogolera Sulphate, ndi Dibosic kutsogolera phosphate.
Monga omaliza okhazikika, zinthu zotsogola siziwononga katundu wamagetsi, mayamwidwe amadzi ochepa, komanso pokana nyengo za papc. Komabe,Kutsogolera Kukhazikikakukhala ndi zovuta monga:
- kukhala ndi poizoni;
- kuipitsidwa, makamaka ndi sulufu;
- Kupanga chitsogozo cha Cloride, komwe kumapangitsa kuti pakhale zinthu zomalizidwa;
- Chiwerengero chachikulu, chomwe chimapangitsa kuti zisakhale zosakwanira.
- Limbikitsani okhazikika nthawi zambiri amapanga zinthu za PVC zopaque nthawi yomweyo ndi discolor mwachangu atatha kutentha.
Ngakhale panali zovutazi, zokhala ndi chikhazikitso zimakhazikitsidwa kwambiri. Kwa kutchinjiriza kwamagetsi, kutsogolera okhazikika kumakonda. Kupindula ndi Zomera zake, zinthu zambiri zosinthika ndi zokhazikika za PVC zimadziwika ngati zigawo zakunja, opaque pvc maadibodi, mapaipi ovuta, otupa, ndi otumphukira.
Kukhazikika Kwachitsulo Kwachitsulo: Kukhazikika kwamitundu yokhazikikandi ophatikizika kwa mitundu yosiyanasiyana, yomwe imapangidwa malinga ndi kugwiritsa ntchito kwa PVC ndi ogwiritsa ntchito. Chitenthetse chotere chasintha kuyambira ma barmailla chokha osakanikirana tokha pakusakanikirana kwa ma sopo, ma sopoxamu, magetsi, mafuta, mafuta, mafuta odzola. Zotsatira zake, pali zinthu zambiri zomwe zingakhudze zotsatira za kukhazikika komaliza.
Okhazikika azitsulo, monga barium, calcium, ndi magnesium sateteza mtundu wa zoyambirira za PVC koma imatha kupewetsa kutentha kwa nthawi yayitali. Zinthu za PVC zomwe zimakhazikika mwanjira iyi zimayamba kutuluka chikasu / lalanje, kenako zimatembenuka pang'ono ku bulauni, ndipo pamapeto pake zakuda pambuyo potentha.
Kukhazikika kwa cadmium ndi zinc adagwiritsidwa ntchito koyamba chifukwa amawonekera ndipo amatha kukhala ndi mtundu woyambirira wa PVC. Kukhazikika kwa nthawi yayitali komwe kumaperekedwa ndi kukhazikika kwa cadmium ndi zinc ndikoyipa kwambiri kuposa zomwe zimaperekedwa ndi mabiliyoni, zomwe zimasokoneza modzidzimutsa kwathunthu kapena ayi.
Kuphatikiza pa chinthu chachitsulo, zotsatira za zolimbitsa mchere zamchere zimagwirizananso ndi mchere mankhwala ena: Pansipa pali zolimbitsa zingapo zofananira: 2-ethylcate, phenolat, benzote, ndi stearate.
Maliro achitsulo achitsulo amagwiritsidwa ntchito kwambiri pazogulitsa zofewa za PVC komanso zowoneka bwino za PVC ngati chakudya, zotama zamankhwala, komanso phukusi la mankhwala.
