E masani ona faʻaaogaina le PVC mo le faʻaofuina o le uaea eletise ona o le sili ona lelei o mea faʻapipiʻi eletise ma le faʻasolosolo faʻasolosolo.O le PVC e masani ona faʻaaogaina i le eletise maualalo (e oʻo atu i le 10 KV), laina fesoʻotaʻiga, ma uaea eletise.

Fa'avae fa'avae mo le gaosiga o le PVC insulation ma le peleue fa'apipi'i mo uaea ma uaea e masani ona aofia ai mea nei:

  1. PVC
  2. Fa'apalaisa
  3. Faatumu
  4. Pigment
  5. Fa'amautu ma fa'amautu fa'atasi
  6. Lubricants
  7. Mea fa'aopoopo (fa'amumu mu, UV-absorbers, etc.)

Filifiliga Plasticizer

E fa'apipi'i i taimi uma mea fa'apipi'i i uaea & uaea fa'a'ese'esega ma peleue e fa'atuputeleina ai le fetu'una'i ma fa'aitiitia ai le pala.E taua tele le faʻaogaina o le palasitika e maualuga le fetaui ma le PVC, maualalo le vaʻaia, lelei mea tuai, ma e leai se eletise.I tua atu o nei manaʻoga, e filifilia le palasitika ma manaʻoga o le oloa maeʻa i le mafaufau.Mo se fa'ata'ita'iga, o se oloa e fa'amoemoe mo le fa'aoga umi i fafo e ono mana'omia se palasitika e sili atu ona lelei le tau nai lo le mea e filifili e se tasi mo na'o totonu o le fale.

Ester phthalate fa'amoemoe lautele pei oleDOP,DINP, maDIDPe masani ona faʻaaogaina e avea ma mea faʻapipiʻi muamua i uaea ma uaea faʻapipiʻi ona o lo latou lautele o le faʻaogaina, lelei mea faʻainisinia, ma mea eletise lelei.TOTMe manatu e sili atu ona talafeagai mo fa'aputuga vevela maualuga ona o lona fa'aitiitiga maualalo.O mea fa'apipi'i PVC e fa'amoemoe mo le fa'aoga maualalo o le vevela e mafai ona sili atu ona lelei i mea fa'a'ilaisa pei oleDOApeDOSlea e tumau ai le fetuutuuna'i maualalo o le vevela sili atu.Suau'u Soya Epoxidized (ESO)e masani ona faʻaaogaina e avea o se co-plasticizer ma stabilizer, talu ai e faʻaopoopoina se faʻaleleia atili o le vevela ma le faʻamautu ata pe a tuʻufaʻatasia ma Ca / Zn poʻo Ba / Zn stabilizers.

Plasticizers i totonu o le uaea ma le cable industry e masani ona faʻamautu i se antioxidant phenolic ina ia faʻaleleia ai mea tuai.O le Bisphenol A o se faʻamautu masani e faʻaaogaina i le tele o le 0.3 - 0.5% mo lenei faʻamoemoe.

Fa'atumu masani

Fillers e faʻaaogaina i uaea & uaea faʻapipiʻi e faʻaitiitia ai le tau o le faʻaogaina aʻo faʻaleleia mea eletise poʻo mea faʻaletino.E mafai ona a'afia lelei mea e fa'atumu ai le fa'afefe o le vevela ma le fa'avevelaina o le vevela.Calcium Carbonate o le faʻatumu sili ona masani mo lenei faʻamoemoe.Silicas e faʻaaogaina foi i nisi taimi.

Pigments i Uaea ma Uaea

E mautinoa lava e fa'aopoopo i ai lanu e tu'ufa'atasia ai le lanu i fa'aputuga.TiO2o le ave lanu e masani ona faʻaaogaina.

Lubricants

Lubricants mo uaea ma uaea e mafai ona i fafo pe i totonu, ma e faʻaaogaina e fesoasoani i le faʻaitiitia o le PVC pipii i luga o le uʻamea vevela o meafaigaluega gaosi.Plasticizers latou lava e mafai ona galue o se lubricant totonu, faapea foi ma le Calcium Stearate.O ava ga'o, ga'o, paraffini ma PEG e mafai ona fa'aoga mo fa'alumaluma fa'aopoopo.

Fa'aopoopo masani i Uaea & Uaea

O mea fa'aopoopo e fa'aaogaina e tu'uina atu ai mea fa'apitoa e mana'omia mo le fa'aaogaina mulimuli o le oloa, mo se fa'ata'ita'iga, mumu mumu po'o le tetee i le tau e le la po'o ni microbes.O le fa'aletonu o le afi ose mana'oga masani mo le fa'atulagaina o uaea ma uaea.O mea fa'aopoopo e pei o le ATO o ni fa'agata mu lelei.O mea fa'apipi'i fa'aaogaina e pei o phosphoric esters e mafai fo'i ona tu'uina atu ni mea e fa'asa ai le mu.E mafai ona fa'aopoopo i ai fa'aoga UV mo fa'aoga fafo e puipuia ai le tau mai le la.O le Carbon Black e aoga tele i le puipuiga mai le malamalama, ae pe a fai o loʻo e faia se mea lanu uliuli pe pogisa.Mo fa'afefiloi lanu felanulanua'i pe manino, e mafai ona fa'aogaina UV-Absorbers fa'avae po'o Benzophenone.Biocides e faʻaopoopoina e puipuia ai faʻalapotopotoga PVC mai le faʻaleagaina e le gaʻo ma microorganisms.OBPA (10′,10′-0xybisphenoazine) e masani ona faʻaaogaina mo lenei faʻamoemoe ma e mafai ona faʻatau mai ua uma ona faʻamavae i totonu o le plasticizer.

Fa'ata'ita'iga Fa'atusa

O loʻo i lalo se faʻataʻitaʻiga o se amataga amata mo se faʻapipiʻiina o le uaea PVC:

Fuafuaga PHR
PVC 100
ESO 5
Ca/Zn po'o le Ba/Zn Stabilizer 5
Fa'apalapala (DOP, DINP, DIDP) 20 – 50
Calcium Carbonate 40- 75
Titanium Dioxide 3
Antimony Trioxide 3
Antioxidant 1
