application

PVC inowanzo shandiswa pamagetsi tambo jaketi nekuda kweakanakisa emagetsi insulating zvivakwa uye dielectric kugara.PVC inowanzoshandiswa mu low voltage cable (kusvika ku10 KV), tambo dzenhare, uye tambo dzemagetsi.

Kuumbwa kwekutanga kwekugadzirwa kwePVC insulation uye jekete makomisheni ewaya uye tambo kazhinji inoumbwa neinotevera:

1. PVC
2. Plasticizer
3. Filler
4. Pigment
5. Stabilizers uye co-stabilizers
6. Mafuta ekuzora
7. Zvinowedzera (zvinodzosa moto, zvinotora UV, nezvimwewo)

Plasticizer Selection

Plasticizers anogara achiwedzerwa kune waya & tambo insulation uye jekete makomisheni kuwedzera kuchinjika uye kuderedza brittleness.Zvakakosha kuti plasticizer inoshandiswa ive nekuenderana kwakanyanya nePVC, kuderera kuderera, kuchembera kwakanaka, uye kuve isina electrolyte.Kupfuura izvi zvinodiwa, mapurasitiki anosarudzwa nezvinodiwa zvechigadzirwa chakapedzwa mupfungwa.Semuenzaniso, chigadzirwa chakagadzirirwa kushandiswa kwenguva refu kunze chingada plasticizer ine mamiriro ekunze ari nani pane angasarudze chinhu chemukati chekushandisa chete chigadzirwa.

General chinangwa phthalate esters akadaiDOP,DINP,uyeDIDPanowanzo shandiswa semaplasticizer ekutanga muwaya uye tambo maumbirwo nekuda kwenzvimbo yavo yakakura yekushandiswa, yakanaka mechanical zvivakwa, uye yakanaka magetsi zvinhu.TOTMinoonekwa seyakakodzerwa neyakakura tembiricha makomisheni nekuda kwekuderera kwayo kuderera.PVC makomisheni akagadzirirwa kushandiswa kwakaderera tembiricha anogona kuita zvirinani nemapurasitiki akadaiDOAkanaDOSiyo inochengetedza yakaderera tembiricha kuchinjika zviri nani.Epoxidized Soybean Oil (ESO)inowanzoshandiswa se-co-plasticizer uye stabilizer, sezvo ichiwedzera synergistic kunatsiridza kupisa uye mufananidzo-kugadzikana kana yasanganiswa neCa/Zn kana Ba/Zn stabilizers.

Plasticizers muwaya uye tambo indasitiri inowanzo dzikamiswa ne phenolic antioxidant kuitira kuvandudza kuchembera zvivakwa.Bisphenol A yakajairika stabilizer inoshandiswa mumhando ye0.3 - 0.5% nekuda kweichi chinangwa.

Kazhinji Anoshandiswa Fillers

Mafiller anoshandiswa muwaya & tambo maumbirwo ekudzikisa mutengo wekomboni uchivandudza magetsi kana emuviri zvivakwa.Mafirita anogona kukanganisa kuchinjisa kupisa uye thermal conductivity.Calcium Carbonate ndiyo inonyanya kuzadza kune chinangwa ichi.Silika dzimwe nguva inoshandiswawo.

Pigments muWaya uye Cable

Pigment inowedzerwawo kupa inosiyanisa ruvara kune makomboni.TiO2iyo inowanzoshandiswa mutakuri wemavara.

Mafuta ekuzora

Mafuta ekuzora waya netambo anogona kunge ari ekunze kana emukati, uye anoshandiswa kubatsira mukudzikisa kwePVC inonamira pane inopisa simbi pamusoro pemidziyo yekugadzirisa.Plasticizers pachavo vanogona kuita semafuta emukati, pamwe neCalcium Stearate.Madoro ane mafuta, wakisi, parafini uye maPEG anogona kushandiswa kuwedzera lubrication.

Zvakajairwa Zvinowedzerwa muWaya & Cable

Zviwedzerwa zvinoshandiswa kugovera zvakakosha zvivakwa zvinodiwa pakupera kwekushandisa kwechigadzirwa, semuenzaniso, murazvo wemoto kana kuramba kutonhora nezuva kana nehutachiona.Flame retardancy chinhu chinowanzoitika kune waya uye tambo dzekugadzira.Zviwedzerwa zvakaita seATO zvinoshanda zvinodzosa moto.Plasticizers anoshandiswa senge phosphoric esters anogona zvakare kupa moto unodzoreredza zvivakwa.UV-absorbers anogona kuwedzerwa kune ekunze kushandiswa kwekushandisa kudzivirira mamiriro ekunze nezuva.Carbon Nhema inoshanda pakudzivirira kubva kuchiedza, asi chete kana uri kugadzira komboni yeruvara dema kana dema.Kune mavara akajeka kana akajeka makomisheni, UV-Absorbers yakavakirwa kana Benzophenone inogona kushandiswa.Biocides inowedzerwa kuchengetedza PVC makomisheni kubva pakushatiswa nefungus uye tupukanana.OBPA (10′,10′-0xybisphenoazine) inowanzoshandiswa nokuda kwechinangwa ichi uye inogona kutengwa yakatonyungudutswa mu plasticizer.
