Zingwe ndi zinthu zofunika kwambiri pa zingwe zamagetsi zamafakitale, zomwe zimaonetsetsa kuti ma siginolo amagetsi amatumizidwa bwino komanso modalirika ku zida zamafakitale. Chingwe cha zingwe ndi chinthu chofunikira kwambiri popereka mphamvu zotetezera kutentha komanso kuteteza chilengedwe. Pamene mafakitale apadziko lonse lapansi akupitiliza kukula, zida zamafakitale zikukumana ndi malo ovuta kwambiri ogwirira ntchito, zomwe zimapangitsa kuti pakhale kufunikira kwakukulu kwa zipangizo zama waya.
Chifukwa chake, kusankha nsalu yoyenera ya chingwe ndikofunikira kwambiri, chifukwa zimakhudza mwachindunji kukhazikika ndi moyo wa chipangizocho.
1. Chingwe cha PVC (Polyvinyl Chloride)
Mawonekedwe:PVCZingwezi zimakhala ndi mphamvu zabwino kwambiri zotetezera nyengo, kukana dzimbiri ndi mankhwala, komanso mphamvu zabwino zotetezera kutentha. Ndi zoyenera kutentha kwambiri komanso kotsika, sizimayaka moto, ndipo zimatha kufewetsedwa posintha kuuma kwake. Ndi zotsika mtengo komanso zimagwiritsidwa ntchito kwambiri.
Malo Ogwiritsira Ntchito: Oyenera malo amkati ndi akunja, zida zopepuka zamakina, ndi zina zotero.
Chidziwitso: Sikoyenera kutentha kwambiri, mafuta ambiri, kapena malo omwe amawonongeka kwambiri. Kukana kutentha koipa komanso kusinthasintha kwa dielectric kumasiyana malinga ndi kutentha. Ikatenthedwa, mpweya woopsa, makamaka hydrochloric acid, umatulutsidwa.
2. Chingwe cha PU (Polyurethane)
Zinthu Zake: Zingwe za PU zimakhala ndi kukana kwabwino kwa kukanda, kukana mafuta, komanso kukana nyengo.
Malo Ogwiritsira Ntchito: Oyenera zida zamafakitale, maloboti, ndi zida zodzichitira zokha m'mafakitale monga makina omanga, mankhwala a petrochemical, ndi ndege.
Zindikirani: Sikoyenera malo otentha kwambiri. Nthawi zambiri amagwiritsidwa ntchito kutentha kuyambira -40°C mpaka 80°C.
3. Chingwe cha PUR (Labala la Polyurethane)
Zinthu Zake: Zingwe za PUR zimapereka kukana kwabwino kwambiri kwa kukanda, kukana mafuta, kukana ozoni, kukana dzimbiri kwa mankhwala, komanso kukana nyengo.
Malo Ogwiritsira Ntchito: Oyenera malo ovuta okhala ndi kukwawa kwambiri, mafuta, ozone, ndi dzimbiri la mankhwala. Amagwiritsidwa ntchito kwambiri mu zida zamafakitale, ma robotiki, ndi automation.
Zindikirani: Sikoyenera kutentha kwambiri. Nthawi zambiri imagwiritsidwa ntchito kutentha kuyambira -40°C mpaka 90°C.
4. Chingwe cha TPE (Thermoplastic Elastomer)
Zinthu Zake: Zingwe za TPE zimapereka mphamvu yabwino kwambiri kutentha pang'ono, kusinthasintha, komanso kukana kukalamba. Zimagwira ntchito bwino kwambiri pa chilengedwe ndipo sizimawononga halogen.
Malo Ogwiritsira Ntchito: Oyenera malo osiyanasiyana a fakitale, zida zamankhwala, mafakitale azakudya, ndi zina zotero.
Chidziwitso: Kukana moto ndi kofooka, sikoyenera malo omwe ali ndi zofunikira kwambiri pachitetezo cha moto.
5. Chingwe cha TPU (Thermoplastic Polyurethane)
Zinthu Zake: Zingwe za TPU zimapereka kukana kwabwino kwambiri kwa kukwawa, kukana mafuta, kukana nyengo, komanso kusinthasintha kwabwino.
Malo Ogwiritsira Ntchito: Oyenera makina aukadaulo, mafakitale a petrochemical, ndi aerospace.
Chidziwitso: Kukana moto ndi kofooka, sikoyenera malo omwe ali ndi zofunikira kwambiri pachitetezo cha moto. Mtengo wake ndi wokwera, komanso wovuta kuukonza pochotsa moto.
6. Chingwe cha PE (Polyethylene)
Zinthu Zake: Zingwe za PE zimakhala ndi mphamvu yolimbana ndi nyengo, kukana dzimbiri ndi mankhwala, komanso mphamvu yabwino yotetezera kutentha.
Malo Ogwiritsira Ntchito: Oyenera malo amkati ndi akunja, zida zopepuka zamakina, ndi zina zotero.
Zindikirani: Sikoyenera kutentha kwambiri, mafuta ambiri, kapena malo ogwiritsidwa ntchito kwambiri.
7. LSZH (Utsi Wochepa Zero Halogen)Chingwe
Zinthu Zake: Zingwe za LSZH zimapangidwa ndi zinthu zachilengedwe monga polyethylene (PE), polypropylene (PP), ndi thermoplastic polyurethane (TPU). Sizimatulutsa mpweya woipa kapena utsi wakuda wambiri zikawotchedwa, zomwe zimapangitsa kuti zikhale zotetezeka kwa anthu ndi zida. Ndi zinthu zachilengedwe zomwe zimagwirizana ndi chingwe.
Malo Ogwiritsira Ntchito: Amagwiritsidwa ntchito makamaka m'malo omwe chitetezo chili chofunika kwambiri, monga malo opezeka anthu ambiri, misewu yapansi panthaka, ngalande, nyumba zazitali, ndi malo ena omwe moto umakhala woopsa.
Zindikirani: Mtengo wokwera, siwoyenera kutentha kwambiri, mafuta ambiri, kapena malo ogwiritsidwa ntchito kwambiri.
8. Chingwe cha AGR (Silicone)
Zinthu Zake: Zingwe za silicone zimapangidwa ndi zinthu za silicone, zomwe zimakhala ndi mphamvu yolimbana ndi asidi, alkali, komanso ma fungicides. Zimatha kupirira kutentha kwambiri komanso chinyezi pomwe zimakhalabe zosinthasintha, zimagwira ntchito bwino kwambiri, komanso zimateteza mphamvu yamagetsi.
Malo Ogwiritsira Ntchito: Angagwiritsidwe ntchito m'malo osiyanasiyana kuyambira -60°C mpaka +180°C kwa nthawi yayitali. Amagwiritsidwa ntchito kwambiri m'mafakitale opanga magetsi, zitsulo, ndi mankhwala.
Zindikirani: Zipangizo za silicone sizimamva kukwawa, sizimalimbana ndi dzimbiri, sizimalimbana ndi mafuta, ndipo zimakhala ndi mphamvu yochepa ya jekete. Pewani malo akuthwa komanso achitsulo, ndipo tikukulimbikitsani kuziyika mosamala.
