Chitoliro cha pulasitiki ndi chida chodziwika bwino chomwe chagwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha pulasitiki yake, mtengo wotsika, wopepuka, komanso kukana dzimbiri. Izi ndi zida zingapo zodziwika bwino zamapaipi apulasitiki ndi madera ogwiritsira ntchito ndi maudindo:

Chitoliro cha PVC:polyvinyl kolorayidi (PVC) chitoliro ndi chimodzi mwa zinthu kwambiri ntchito chitoliro zipangizo ndi angagwiritsidwe ntchito madzi, gasi, zimbudzi, kufala mafakitale, etc. PVC chitoliro ali kukana dzimbiri, kukana kuthamanga, kusindikiza zabwino, mtengo wotsika, ndi zina zotero.

PE pipe:polyethylene (PE) chitoliro ndi wamba zakuthupi chitoliro, makamaka ntchito m'madzi, gasi, zimbudzi, etc. PE chitoliro ali zimakhudza kukana, kukana dzimbiri, kusinthasintha wabwino, ndi zina zotero.

PP-R chitoliro:polypropylene mwachisawawa copolymer (PP-R) chitoliro angagwiritsidwe ntchito kachitidwe madzi m'nyumba, Kutentha pansi, firiji, etc. PP-R chitoliro ali ndi kutentha kukana, asidi, ndi kukana zamchere, si kophweka lonse, ndi zina zotero. pa.

Chitoliro cha ABS:Chitoliro cha ABS ndi chida chosagwira ntchito, chosagwirizana ndi dzimbiri, chomwe chimagwiritsidwa ntchito kwambiri poyeretsa zimbudzi, zimbudzi zakukhitchini, ndi madera ena.

Pulogalamu ya PC:chitoliro cha polycarbonate (PC) chili ndi mphamvu zambiri, kuwonekera kwambiri, ndi mawonekedwe ena, ndipo angagwiritsidwe ntchito m'misewu yayikulu, machubu, ma subways, ndi madera ena omanga.

PA PA:polyamide (PA) chitoliro makamaka ntchito m'munda wa mpweya, mafuta, madzi, ndi zina zamadzimadzi transport.PA chitoliro ndi dzimbiri zosagwira, kutentha zosagwira, kuthamanga zosagwira, ndi makhalidwe ena.

Zida zosiyanasiyana za pulasitiki zitoliro ndizoyenera kumadera osiyanasiyana. Kawirikawiri, mapaipi apulasitiki ali ndi ubwino wokhala opepuka, otsika mtengo, osagwirizana ndi dzimbiri, okonzeka kumanga, ndi zina zotero, ndipo pang'onopang'ono amalowa m'malo mwa mipope yachitsulo, ndipo amagwira ntchito yofunika kwambiri pa zomangamanga zamakono.

Komabe, mavuto ena omwe amapezeka nthawi zambiri amatha kukumana ndi kupanga ndi kukonza mapaipi apulasitiki, kuphatikiza:

Kusasungunuka kwamadzimadzi:zida zina zapulasitiki pakukonza, chifukwa cha mawonekedwe a unyolo wa ma cell ndi zinthu zina, zimatha kupangitsa kuti madzi asasungunuke bwino, zomwe zimapangitsa kuti pakhale kudzaza kosagwirizana ndi njira yopangira jekeseni kapena jekeseni, kusagwira bwino pamwamba, ndi zovuta zina.

Kusakhazikika kwa dimensional:zina mwa zipangizo za pulasitiki mu processing ndi kuzirala ndondomeko shrinkage, mosavuta kutsogolera osauka dimensional bata la chomalizidwa, kapena mapindikidwe ndi mavuto ena.

Kutsika koyipa:Pakapangidwe ka extrusion kapena jekeseni, chifukwa cha mapangidwe opangidwa mopanda nzeru a nkhungu, kuwongolera kosayenera kwa kutentha kwasungunuka, etc., kungayambitse zolakwika monga kusagwirizana, thovu, kufufuza, ndi zina zotero pamwamba pa zinthu zomalizidwa.

Kulephera kupirira kutentha:zida zina za pulasitiki zimafewetsa ndi kupunduka pa kutentha kwakukulu, zomwe zingakhale zovuta kwa ntchito zapaipi zomwe zimafunika kupirira malo otentha kwambiri.

Kusakwanira kwamphamvu kwamphamvu:zida zina zapulasitiki zilibe mphamvu zambiri zokha, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zamphamvu zamakakodwe muzinthu zina zaumisiri.

Mavutowa amatha kuthetsedwa pokonza mapangidwe azinthu zopangira, kukhathamiritsa njira zopangira, ndikuwongolera kapangidwe ka nkhungu. Nthawi yomweyo, ndizothekanso kuwonjezera zida zapadera zolimbikitsira, zodzaza, zothira mafuta, ndi zida zina zothandizira kukonza magwiridwe antchito a mapaipi apulasitiki komanso mtundu wazinthu zomalizidwa. Kwa zaka zambiri, PPA (Polymer Processing Additive) zothandizira zopangira fuloropolymer zasankhidwa ndi opanga mapaipi ambiri ngati mafuta.

PPA (Polymer Processing Additive) zowonjezera zowonjezera za fluoropolymer popanga zitoliro zimagwiritsidwa ntchito makamaka kupititsa patsogolo ntchito yokonza, kukonza zinthu zomalizidwa, komanso kuchepetsa ndalama zopangira. Nthawi zambiri imakhala ngati mafuta, ndipo imatha kuchepetsa kukana kwamphamvu, ndikuwongolera kusungunuka kwamadzimadzi ndi kudzaza pulasitiki, motero kumapangitsa kuti pakhale zokolola komanso mtundu wazinthu munjira yopangira jekeseni kapena jekeseni.

Padziko lonse lapansi, PFAS imagwiritsidwanso ntchito kwambiri m'mafakitale ambiri ndi ogula, koma kuopsa kwake kwa chilengedwe komanso thanzi la anthu kwadzetsa nkhawa. Ndi European Chemicals Agency (ECHA) ikupangitsa kuti zoletsa za PFAS ziwonekere mu 2023, opanga ambiri ayamba kufunafuna njira zina zothandizira PPA fluoropolymer processing.

Kuthana ndi zosowa zamsika ndi njira zopangira zatsopano——SILIKE LaunchesPFAS-Free Polymer Processing Aid (PPA)

Potengera zomwe zikuchitika masiku ano, gulu la SILIKE la R&D lachita khama lalikulu popangaPFAS-free polima processing aids (PPAs)pogwiritsa ntchito njira zamakono zamakono ndi kulingalira kwatsopano, zomwe zimathandizira pachitetezo cha chilengedwe ndi chitukuko chokhazikika.

SILIKE Fluorine-Free PPAimapewa kuopsa kwa chilengedwe ndi thanzi lomwe limakhudzana ndi mankhwala azikhalidwe a PFAS ndikuwonetsetsa kuti zinthuzo zikuyenda bwino.SILIKE Fluorine-Free PPAsikuti zimangotsatira zoletsa za PFAS zofalitsidwa ndi ECHA komanso zimapereka njira yotetezeka komanso yodalirika pazophatikiza zachikhalidwe za PFAS.

SILIKE Fluorine-Free PPAndi PFAS-free polima processing aid (PPA) yochokera ku SILIKE. Chowonjezeracho ndi chinthu chosinthidwa cha polysiloxane chomwe chimagwiritsa ntchito mwayi woyambira bwino wamafuta a polysiloxanes ndi polarity yamagulu osinthidwa kuti asamukire ndikuchitapo kanthu pazida zopangira.

SILIKE Fluorine-Free PPA itha kukhala choloweza m'malo mwa fluorine-based PPA zothandizira pokonza. Kuwonjezera pang'ono pang'onoSILIKE Fluorine-Yaulere PPA SILIMER 5090,Mtengo wa 5091akhoza bwino kusintha utomoni fluidity, processability, kondomu, ndi katundu pamwamba pulasitiki extrusion, kuthetsa kusweka kusungunuka, kusintha kuvala kukana, kuchepetsa coefficient wa mikangano, ndi kusintha zokolola ndi khalidwe mankhwala pokhala wokonda zachilengedwe ndi otetezeka.

Udindo waSILIKE Fluorine-Yaulere PPA SILIMER 5090popanga mapaipi apulasitiki:

Kuchepetsa mkati ndi kunja kwakekusiyana: Mu extrusion ndondomeko ya mipope, kugwirizana kwa diameters wamkati ndi kunja n'kofunika kwambiri. Kuwonjezera kwaSILIKE Fluorine-Yaulere PPA SILIMER 5090amachepetsa kukangana pakati pa kusungunula ndi kufa, kumachepetsa kusiyana kwa mkati ndi kunja kwa m'mimba mwake, ndikuonetsetsa kuti chitolirocho chikhale chokhazikika.

Kumaliza bwino kwapamwamba:SILIKE Fluorine-Yaulere PPA SILIMER 5090imathandizira bwino kumapeto kwa chitoliro, ndikuchepetsa kupsinjika kwamkati ndikusungunula zotsalira, zomwe zimapangitsa kuti paipi ikhale yosalala yokhala ndi ma burrs ochepa komanso zilema.

Mafuta owonjezera:SILIKE Fluorine-Yaulere PPA SILIMER 5090amachepetsa kukhuthala kwa mapulasitiki ndikuwongolera kuchuluka kwamafuta, kuwapangitsa kuti aziyenda mosavuta ndikudzaza zisankho, motero zimachulukitsa zokolola mu njira zopangira ma extrusion kapena jekeseni.

Kuchotsa kusweka kwa chitsulo:Kuwonjezera kwaSILIKE Fluorine-Yaulere PPA SILIMER 5090amachepetsa coefficient of friction, amachepetsa torque, bwino mkati ndi kunja kondomu, bwino kuthetsa kusungunuka kusweka, ndi kumawonjezera moyo utumiki wa chitoliro.

Kuwongola kukana kuvala: SILIKE Fluorine-Yaulere PPA SILIMER 5090imathandizira kukana kwa abrasion kwa chitoliro, ndikupangitsa kuti ikhale yoyenera kwambiri pazogwiritsa ntchito zomwe zimafuna kukana kwa abrasion.

Kuchepetsa kugwiritsa ntchito mphamvu:Chifukwa cha kuthekera kwake kuchepetsa kusungunuka kwa ma viscosity ndi kukana kukangana,SILIKE Fluorine-Free PPAamachepetsa kugwiritsa ntchito mphamvu panthawi ya extrusion kapena jekeseni, motero kuchepetsa ndalama zopangira.

SILIKE Fluorine-Free PPAali ndi ntchito zosiyanasiyana, osati machubu okha komanso mawaya ndi zingwe, mafilimu, masterbatches, petrochemicals, metallocene polypropylene(mPP), metallocene polyethylene(mPE), ndi zina. Komabe, mapulogalamu apadera amayenera kusinthidwa ndikuwongoleredwa malinga ndi zida zosiyanasiyana komanso zofunikira pakupanga. Ngati muli ndi mafunso okhudza zilizonse zomwe zili pamwambapa, SILIKE ndiwokondwa kulandila zomwe mwafunsa, ndipo tili ofunitsitsa kufufuza madera ogwiritsira ntchito PFAS-free polima processing aids (PPA) nanu.
