Momwe Liquid Kalium Zinc PVC Stabilizers Amathetsera Kupweteka Kwambiri Kumutu

PVC idakalipobe pakupanga, koma chidendene chake cha Achilles - kuwonongeka kwa kutentha panthawi yokonza - kwavutitsa opanga kwa nthawi yayitali. Lowanimadzi kalium zinki PVC stabilizers: yankho lamphamvu lomwe limathana ndi zovuta za zinthu zomwe zimakhudzidwa kwambiri ndikuwongolera kupanga. Tiyeni tiwone momwe zowonjezera izi zimasinthira kupanga PVC

Imayimitsa Kuwonongeka kwa Matenthedwe M'mayendedwe Ake

PVC imayamba kutsika potentha mpaka 160°C, kutulutsa mpweya woipa wa HCl ndi zinthu zomwe zimasanduka brittle kapena kusinthika. Zamadzimadzi kalium zinc stabilizers amachita ngati chishango chodzitchinjiriza, kuchedwetsa kuwonongeka mwa kusokoneza HCl ndikupanga ma complex okhazikika ndi tcheni cha polima. Mosiyana ndi zitsulo zokhazikika zachitsulo zomwe zimatuluka mofulumira, kalium-zinc combo imapereka chitetezo chowonjezereka-kusunga PVC kukhala yokhazikika ngakhale pa nthawi yayitali yothamanga pa 180-200 ° C. Izi zikutanthawuza kuti magulu ochepa okanidwa chifukwa cha chikasu kapena kusweka, makamaka muzinthu zowonda monga mafilimu ndi mapepala.

Imathetsa Bottlenecks Processing

Opanga amadziwa kukhumudwa kwa kutsekedwa kwa mizere pafupipafupi. Zikhazikiko zachikhalidwe nthawi zambiri zimasiya zotsalira pamafa ndi zomangira, kukakamiza kuyimitsa kuyeretsa maola 2-3 aliwonse. Madzi a kalium zinc mafomu, komabe, amakhala ndi mamasukidwe otsika omwe amayenda bwino kudzera pazida, kuchepetsa kuchulukana. Wopanga zitoliro m'modzi adanenanso kuti akudula nthawi yoyeretsa ndi 70% atasintha, ndikuwonjezera zotulutsa zatsiku ndi tsiku ndi 25%. Mawonekedwe amadzimadzi amasakanikirana mofanana ndi utomoni wa PVC, kuchotsa kugwa komwe kumayambitsa makulidwe osagwirizana mu mbiri kapena mapaipi.

Imakulitsa Kukhalitsa mu Zogulitsa Zomaliza

Sizongopanga zokha - kugwiritsa ntchito komaliza kumafunikanso. Zinthu za PVC zothandizidwa ndiKalium zinc stabilizerswonetsani kukana kwamphamvu ku kuwala kwa UV ndi chinyezi, kukulitsa nthawi ya moyo muzakunja ngati mafelemu a zenera kapena mapaipi amunda. Muzinthu zosinthika monga ma gaskets kapena machubu azachipatala, stabilizer imasunga kukhazikika pakapita nthawi, kuteteza kuuma komwe kumabweretsa kutulutsa kapena kulephera. Mayesero akuwonetsa kuti mankhwalawa amasunga 90% ya mphamvu zawo zolimba pambuyo pa maola 500 okalamba kwambiri, zomwe zimapambana zomwe zimapangidwa ndi zowonjezera zowonjezera.

Imakumana ndi Miyezo Yolimba Yachitetezo

Kukakamizidwa kwa malamulo kukuchulukirachulukira pazowonjezera zotetezedwa za PVC, makamaka pazakudya kapena zinthu zachipatala. Zolimbitsa thupi za kalium zinc fufuzani mabokosi onse: alibe zitsulo zolemera monga lead kapena cadmium, ndipo kutsika kwawo kumawapangitsa kuti azitsatira malamulo a FDA ndi EU 10/2011. Mosiyana ndi ma organic stabilizer omwe amachotsa mankhwala, fomulayi imakhala yotsekeka mu polima matrix - yofunika kwambiri pakugwiritsa ntchito ngati zotengera chakudya kapena zoseweretsa za ana.

Zotsika mtengo Popanda Kunyengerera

Kusinthira ku zowonjezera zowonjezera nthawi zambiri kumatanthauza mtengo wokwera, koma osati pano. Zamadzimadzi kalium zinki stabilizers amafuna 15-20% mlingo wochepa kuposa njira zolimba kuti akwaniritse zotsatira zomwezo, kudula ndalama zopangira. Kuchita bwino kwawo kumachepetsanso kugwiritsa ntchito mphamvu: kukonza bwino kumachepetsa kutentha kwa extrusion ndi 5-10 ° C, kudula ndalama zothandizira. Kwa opanga ang'onoang'ono mpaka apakati, zosungirazi zimawonjezeka mwachangu - nthawi zambiri zimabwezera mtengo wosinthira mkati mwa miyezi 3-4.

Uthengawu ndi womveka bwino: zolimbitsa thupi za kalium zinc sizingokonza mavuto a PVC-zimafotokozeranso zomwe zingatheke. Pophatikiza chitetezo chamafuta, kukonza bwino, ndi chitetezo, akukhala njira yabwino kwa opanga omwe amakana kupereka mtengo wake. Pamsika momwe kudalirika ndi kutsata sikungakambidwe, chowonjezera ichi sichimangowonjezera-ndichofunikira.

Zotsatira TOPJOY ChemicalKampani yakhala ikudzipereka ku kafukufuku, chitukuko, ndi kupanga zinthu zapamwamba za PVC zokhazikika. Gulu la akatswiri a R&D la Topjoy Chemical Company limapitirizabe kupanga zatsopano, kukhathamiritsa zopanga zinthu molingana ndi zofuna za msika ndi momwe makampani akutukukira, ndikupereka mayankho abwinoko pamabizinesi opangira. Ngati mukufuna kudziwa zambiri za PVC stabilizers, ndinu olandiridwa kuti mutilankhule nthawi iliyonse!
