isicelo

I-PVC isoloko isetyenziselwa ukuvala intambo yombane ngenxa yeempawu zayo ezibalaseleyo zokugquma umbane kunye ne-dielectric engaguqukiyo.I-PVC iqhele ukusetyenziswa kwintambo yombane ophantsi (ukuya kuthi ga kwi-10 KV), iintambo zonxibelelwano, kunye neentambo zombane.

Ukuqulunqwa okusisiseko kwimveliso yePVC yokugquma kunye neekhompawundi zebhatyi yocingo kunye nentambo ngokubanzi iqulunqwe ngolu hlobo lulandelayo:

1. I-PVC
2. Iplastiki
3. Isigcwalisi
4. Ibala lebala
5. Izinzisi kunye nezizinzisi ngokubambisana
6. Izithambisi
7. Izongezo (izithambisi zomlilo, i-UV-absorbers, njl.

Ukukhethwa kwePlastiki

IiPlastiki zihlala zongezwa kwi-wire & cable insulation kunye neekhompawundi zebhatyi ukunyusa ukuguquguquka kunye nokunciphisa i-brittleness.Kubalulekile ukuba i-plasticizer esetyenzisiweyo ibe nokuhambelana okuphezulu kunye ne-PVC, ukuguquguquka okuphantsi, iimpawu ezilungileyo zokuguga, kwaye ingabi ne-electrolyte.Ngaphandle kwezi mfuno, iiplastiki zeplastiki zikhethwa kunye neemfuno zemveliso egqityiweyo engqondweni.Umzekelo, imveliso eyenzelwe ukusetyenziswa ixesha elide ngaphandle ingafuna iplastiki eneempawu ezingcono zemozulu kunokuba umntu angakhetha ukusetyenziswa kwemveliso yangaphakathi kuphela.

Injongo ngokubanzi phthalate esters ezifanaDOP,I-DINP, kwayeI-DIDPzidla ngokusetyenziswa njengeplastiki eziziiprayistiki eziziiprayimari eziziiprayimari eziziiprayimari eziziintloko kwiingcingo kunye necable formulations ngenxa yendawo yazo ebanzi yokusetyenziswa, iipropathi ezilungileyo zomatshini, kunye neempawu ezilungileyo zombane.I-TOTMithathwa njengento efanelekileyo kakhulu kwiikhompawundi eziphezulu zokushisa ngenxa yokuguquguquka kwayo okuphantsi.Iikhompawundi zePVC ezenzelwe ukusetyenziswa kobushushu obuphantsi zinokwenza ngcono ngeeplasticizers ezifanaI-DOAokanyeI-DOSezigcina ukuguquguquka kobushushu obuphantsi ngcono.I-Epoxidized Soy Oil (ESO)isoloko isetyenziswa njenge-co-plasticizer kunye ne-stabilizer, ekubeni yongeza ukuphuculwa kwe-synergistic ye-thermal kunye ne-photo-stability xa idibene ne-Ca / Zn okanye i-Ba / Zn stabilizers.

Iiplastiki kwishishini locingo kunye nentambo zihlala zizinzile kunye ne-phenolic antioxidant ukwenzela ukuphucula iimpawu zokuguga.I-Bisphenol A yi-stabilizer eqhelekileyo esetyenziswa kuluhlu lwe-0.3 - 0.5% kule njongo.

IiFillers ezisetyenziswa ngokuqhelekileyo

Iifayili zisetyenziselwa kwi-wire & i-cable formulations ukunciphisa ixabiso le-compound ngelixa uphucula izinto zombane okanye ezibonakalayo.Ukuzalisa kunokuchaphazela kakuhle ukuhanjiswa kobushushu kunye ne-thermal conductivity.I-Calcium Carbonate yeyona nto ixhaphakileyo yokuzalisa le njongo.Ngamanye amaxesha kusetyenziswa iisilica.

IiPigments kwiNcingo kunye neCable

Ii-pigments ngokuqinisekileyo zongezwa ukunika umbala owahlulayo kwiikhompawundi.I-TiO2owona mbala usetyenziswa kakhulu.

Izithambisi

I-Lubricants yocingo kunye nekhebula ingaba yangaphandle okanye yangaphakathi, kwaye isetyenziselwa ukuncedisa ekunciphiseni i-PVC enamathele kwiindawo ezishushu zetsimbi zezixhobo zokusebenza.IiPlastiki ngokwazo zinokusebenza njenge-lubricant yangaphakathi, kunye neCalcium Stearate.Utywala obunamafutha, iwax, iparafini kunye nee-PEGs zingasetyenziselwa ukuthambisa okongeziweyo.

Izongezo eziqhelekileyo kwiNcingo kunye neCable

Izongezo zisetyenziselwa ukunika iimpawu ezikhethekileyo ezifunekayo ekupheliseni ukusetyenziswa kwemveliso, umzekelo, ukutshatyalaliswa komlilo okanye ukuchasana nokushisa kwelanga okanye nge-microbes.I-flame retardancy iyimfuneko eqhelekileyo yocingo kunye ne-cable formulations.Izongezo ezifana ne-ATO zisebenza ngokubuyisela amadangatye.IiPlastiki ezisetyenziswa njenge-phosphoric esters nazo zinokunikezela ngeempawu zokubuyiswa komlilo.Izifunxa ze-UV zinokongezwa kusetyenziso lwangaphandle ukunqanda ukushisa kwelanga.ICarbon Black iyasebenza ekukhuseleni ekukhanyeni, kodwa kuphela ukuba wenza ikhompawundi emnyama okanye emnyama.Kwizinto ezinemibala eqaqambileyo okanye ecacileyo, i-UV-Absorbers esekelwe okanye i-Benzophenone ingasetyenziswa.Ii-biocides zongezwa ukukhusela i-PVC iikhompawundi ekuthotyweni yi-fungus kunye ne-microorganisms.I-OBPA (10′,10′-0xybisphenoazine) isetyenziswa rhoqo kule njongo kwaye inokuthengwa esele ichithwe kwi-plasticizer.
