I-PVC ngocingo kunye neCable: iiPropati zeMathiriyeli eziBalulekileyo

1.PVC Resin

I-resin ye-PVC yipolymer ye-thermoplastic ehambelanayo eyenziwe yi-polymerization ye-vinyl chloride monomers. Ubume bayo bemolekyuli buneempawu:

(1) Njengepolymer ye-thermoplastic, ibonisa iplastiki efanelekileyo kunye nokuguquguquka.

(2) Ubukho beebhondi ze-C-Cl ze-polar zinika i-resin polarity eyomeleleyo, okubangela ukuba i-dielectric ihlale iphezulu (ε) kunye ne-dissipation factor (tanδ), ngelixa inikezela amandla aphezulu e-dielectric kumaza aphantsi. Ezi bhondi ze-polar nazo zinegalelo kumandla anamandla e-intermolecular kunye namandla aphezulu omatshini.

(3) Iiathom zeklorini kwisakhiwo semolekyuli zinika iimpawu zokunqanda amadangatye kunye nokuxhathisa okuhle kweekhemikhali kunye nemozulu. Nangona kunjalo, ezi athom zeklorini ziphazamisa ukwakheka kwekristale, okukhokelela ekuxhathiseni ubushushu obuphantsi kunye nokuxhathisa okubandayo okubandayo, okunokuphuculwa ngokusebenzisa izongezo ezifanelekileyo.

2.Iintlobo zePVC Resin

Iindlela ze-polymerization ze-PVC ziquka: ukumiswa kwe-polymerization, i-emulsion polymerization, i-polymerization yobuninzi, kunye ne-polymerization yesisombululo.

Indlela yokunqunyanyiswa kwepolymerization okwangoku iphambili kwimveliso ye-PVC ye-resin, kwaye olu luhlobo olusetyenziswa kwizicelo zocingo kunye nentambo.

Iinreyithi zePVC ezimisiweyo zepolymerized zahlulwa zibe ziindlela ezimbini:
I-resin yohlobo olukhululekile (uhlobo lwe-XS): Ibonakaliswe ngesakhiwo se-porous, i-plasticizer absorption ephezulu, i-plastification elula, ukulawulwa kwenkqubo efanelekileyo, kunye neencinci ze-gel ezimbalwa, okwenza kube yinto ekhethiweyo yocingo kunye nezicelo zentambo.
I-resin yohlobo lwe-Compact (uhlobo lwe-XJ): Isetyenziswa kakhulu kwezinye iimveliso zeplastiki.

3. Iimpawu eziphambili zePVC

(1) IiPropati ze-Insulation zoMbane: Njengombane we-dielectric we-polar, i-resin ye-PVC ibonisa izinto ezintle kodwa ezingaphantsi kancinci zombane zokugquma xa kuthelekiswa nezinto ezingezo-polar ezifana ne-polyethylene (PE) kunye ne-polypropylene (PP). Ukuxhathisa umthamo kudlula 10¹⁵ Ω·cm; kwi-25 ° C kunye ne-50Hz i-frequency, i-dielectric constant (ε) isuka kwi-3.4 ukuya kwi-3.6, ihluke kakhulu ngokutshintsha kweqondo lokushisa kunye nobuninzi; i-disipation factor (tanδ) isuka kwi-0.006 ukuya kwi-0.2. Amandla okuqhekeka ahlala ephezulu kwiqondo lobushushu begumbi kunye nokuphindaphindwa kwamandla, angachatshazelwa yi-polarity. Nangona kunjalo, ngenxa yelahleko yayo ephezulu ye-dielectric, i-PVC ayifanelekanga usetyenziso lwe-voltage ephezulu kunye ne-high-frequency, ngokuqhelekileyo isetyenziswa njengempahla yokugquma kwiintambo zombane eziphantsi kunye neziphakathi ngaphantsi kwe-15kV.

(2) Ukuguga Ukuzinza: Nangona isakhiwo se-molecular sibonisa ukuzinza okulungileyo kokuguga ngenxa yebhondi ye-chlorine-carbon, i-PVC ithambekele ekukhululeni i-hydrogen chloride ngexesha lokucubungula phantsi koxinzelelo lwe-thermal kunye nomatshini. I-oxidation ikhokelela ekuthotyweni okanye ekudityanisweni kwe-cross-link, kubangele ukuguquguquka kwebala, u-embrittlement, ukwehla okuphawulekayo kwiipropati ze-mechanical, kunye nokuwohloka kokusebenza kokufakelwa kombane. Ke ngoko, izizinzi ezifanelekileyo kufuneka zongezwe ukuphucula ukumelana nokuguga.

3 Ngobushushu bokutshintsha kweglasi (Tg) malunga ne-80 ° C kunye nobushushu bokuhamba malunga ne-160 ° C, i-PVC kwimeko yayo yeglasi kwindawo yobushushu begumbi ayinakuhlangabezana neemfuno zocingo kunye nentambo yesicelo. Ukuguqulwa kuyimfuneko ukufezekisa u-elasticity ephezulu kwiqondo lokushisa kwegumbi ngelixa ugcina ukushisa okwaneleyo kunye nokumelana nokubanda. Ukongezwa kweeplasticizers kunokulungelelanisa ngokufanelekileyo iqondo lokushisa lokutshintsha kweglasi.

MalungaILIZWE ELINYE (OW Cable)

Njengomthengisi ohamba phambili wocingo kunye nemathiriyeli yentambo ekrwada, IZWE ELINYE (i-OW Cable) ibonelela ngezixhobo ezikumgangatho ophezulu zePVC zokugquma kunye nosetyenziso lwe-sheathing, olusetyenziswa ngokubanzi kwiintambo zamandla, iingcingo zokwakha, iintambo zonxibelelwano, kunye neentambo zemoto. Izinto zethu ze-PVC zibonisa ukugquma kombane okugqwesileyo, ukunqandwa komlilo, kunye nokumelana nemozulu, ukuthobela imigangatho yamazwe ngamazwe efana ne-UL, RoHS, kunye ne-ISO 9001. Sizimisele ukuhambisa izisombululo ze-PVC ezithembekileyo nezingabizi kakhulu ezilungiselelwe iimfuno zabathengi bethu.
