Fa'atomuaga i Uea PVC U'a Ma'a'a'a ma Uea Uea
Ole asu maualalo ole PVC (Polyvinyl Chloride) uaea ma uaea uaea o mea fa'apitoa fa'avelavela ua fuafuaina e fa'aitiitia ai le asu ma le kasa oona i le taimi o le mu. Ole mea lea e avea ai i latou ma filifiliga taua mo fa'aoga e fa'amuamua ai le saogalemu o le afi. E masani ona fa'aogaina mo le fa'a'ese'ese ma le peleue i uaea eletise, o nei mea fa'apipi'i e ofoina atu le tele o vaega taua:
Tulaga:O fa'aputuga PVC asu maualalo o lo'o fa'apipi'iina i le tu'ufa'atasiga o resini PVC, palasitika (e pei o le dioctyl phthalate ma le tri-2-ethylhexyl trimellitate), fa'amalama afi (fa'ata'ita'iga, antimony trioxide, alumini trihydrate, ma le zinc borate), fa'amautu (calcium/zinc-based), fa'atumu (calcium carbonate), ma lubricants.
Meatotino asu maualalo:E le pei o le PVC masani, lea e mafai ona faʻaitiitia ai le vaʻaia e oʻo atu i le 90% i le na o le 30 minute ona o le asu mafiafia, faʻapipiʻiina le asu o le PVC e faʻamalieina tulaga saogalemu e pei o le BS EN 61034. O nei mea faʻapipiʻi e mafai ai ona le itiiti ifo i le 60% le feʻaveaʻi o le malamalama i le taimi o le afi, faʻaleleia atili le saogalemu.
Fa'asa'o o le afi: O le PVC o lo'o i ai ni mea e fa'asa'o ai le afi ona o lona chlorine, lea e fa'aopoopoina i mea fa'aopoopo e fa'aluma ai le afi. O nei mea faʻapipiʻi e fetaui ma tulaga faʻapitoa e pei o le IEC 60332-1-2, UL VW1, ma le E84 (faʻasinomaga faʻasalalau afi <25, faʻasino asu atiina ae <50).
Talosaga:E masani ona fa'aogaina i totonu o siosiomaga lamatia e pei o nofoaga autu o fa'amaumauga, tunnels, va'alele, taavale afi, ma fale faitele, uaea PVC maualalo asu ma uaea fa'apipi'i e taua tele mo le fa'aitiitia o a'afiaga e feso'ota'i ma le asu ma le asu oona pe a mu.
Lu'i masani Fa'agaioiga ma Fofo mo Uea PVC Ma'a'a Asu ma Uaea Fa'aputuga
O le fa'agaioiina o fa'aputuga PVC e maualalo le asu e aofia ai le fa'afoeina o lu'itau eseese, ae maise lava ona o le lavelave o le fa'atulagaina. I lalo, matou te talanoaina nisi o faʻafitauli sili ona taatele ma a latou fofo:
1. Fa'atumu maualuga mea e tau atu i le le lelei o le fe'avea'i ma le maualuga maualuga
Lu'i:Ina ia ausia mea e maualalo le asu, o mea faʻapipiʻi PVC e masani ona iai le maualuga o mea faʻatumu e pei ole alumini trihydrate (ATH) poʻo le magnesium hydroxide (Mg(OH)₂) - e masani lava 20-60% i le mamafa. E ui ina fa'aitiitia e nei mea fa'atumu le asu ma le mumu, e mafai ona fa'ateleina le viscosity, fa'aitiitia le tafe, ma mafua ai ona ofuina meafaigaluega.
Tali:
Fa'aaofia ai fesoasoani e fa'agaioi ai e pei o lubricant totonu/fafo (fa'ata'ita'iga, calcium stearate, polyethylene waxes, po'omea fa'aopoopo silicone) i le 0.5-2.0 phr e faʻaititia ai le viscosity ma faʻaleleia le tafe.
Fa'aaogā mea fa'apipi'i lua-screw maualuga L/D e fa'aleleia atili ai le fa'afefiloi ma le fa'atumu o fa'asalalauga.
Fa'aaogā faiga kuki fa'atasi ai ma le fafaga fa'atosina e fa'amautinoa le tu'ufa'atasiga tutusa.
Filifili mea fa'atumu e fa'atonuina le lapopo'a o fasimea ma togafitiga i luga e fa'aleleia atili ai le fetaui ma fa'aitiitia le abrasion.
2. Mausali Fa'avela
Lu'i:O le PVC e mafai ona faʻaleagaina i le taimi o le gaosiga, aemaise lava i le maualuga o le faʻatumu ma le mumu o le afi, faʻasaʻo le hydrogen chloride (HCl) gas e oʻo atu ai i mea faʻaleagaina, lanu, ma mea e pala.
Tali:
Fa'aopoopo mea fa'amautu vevela e pei o fa'amautu fa'avae calcium/zinc i le 2-4 phr e fa'aleaogaina ai le HCl ma puipuia ai le fa'aleagaina.
Fa'aaoga le suau'u soya epoxidized (ESO) e fai ma fa'amautu mo le fa'aleleia atili o le vevela ma le mautu o ata.
Pulea lelei le vevela o le gaosiga (160-190°C) ina ia aloese mai le vevela tele.
Fa'aaofia phenolic antioxidants (fa'ata'ita'iga, Bisphenol A i le 0.3-0.5%) e fa'aleleia ai le fa'atupuina o le matua i le taimi o gaioiga.
3. Plasticizer Migration
Lu'i:O mea fa'apipi'i fa'aaoga e fa'aleleia atili ai le fetu'una'i e mafai ona femalaga'i i lalo ole vevela tele (fa'ata'ita'iga, i nofoaga autu o fa'amaumauga), e o'o atu ai i fa'aputuga o totoe e ono fa'alavelave ai le fa'asalalauina o fa'ailo pe fa'aitiitia ai le umi o le uaea.
Tali:
Fa'aaogā mea fa'apipi'i polymeric e le femalaga'i nai lo mea fa'ameamea (fa'ata'ita'iga, DOP, DINP) e fa'aitiitia ai femalagaiga.
Atiae "le-vai" plenum formulas, e pei ona paionia e OTECH, e taofia ai le femalagaiga o plasticizer i siosiomaga maualuga-vevela.
Filifili mo plasticizers pei o TOTM, lea e maualalo le faʻaogaina ma e sili atu ona talafeagai mo talosaga maualuga-vevela.
4. Fa'apaleni le Mumu ma le Taofia o le Asu
Lu'i:O le fa'atuputeleina o le mu e ala i mea fa'aopoopo e pei o le antimony trioxide (3-5%) po'o mea fa'apalapala (12-15%) e mafai ona fa'ateleina ai le asu o le asu, ma avea ai ma lu'itau le paleni o mea uma e lua. E fa'apena fo'i, o mea fa'atumu e pei o le calcium carbonate e mafai ona fa'aitiitia ai le asu ae e ono fa'aititia ai le fa'ailoga o le okesene, e a'afia ai le mu.
Tali:
Fa'aoga tu'ufa'atasiga e fa'asa'o ai le mu (fa'ata'ita'iga, ATH ma le zinc borate) e fa'amalieina uma le mu ma le tapeina o le asu. O le ATH, mo se faʻataʻitaʻiga, e tuʻuina atu le ausa vai e faʻalavelave ai le afi ma fausia ai se faʻamalama puipui, e faʻaitiitia ai le asu.
Fa'atapula'a le utaina o le CaCO₃ i le 20-40 phr e maua ai se paleni i le va o le tau, taofiofia o le asu, ma le mumu o le afi, ona o le tele o aofaiga e mafai ona fa'aitiitia ai le fa'ailoga o le okesene.
Su'esu'e faiga PVC e mafai ona feso'ota'i, e pei ole PVC feso'ota'i fa'avevela, e fa'aleleia ai le mu e aunoa ma le fa'alagolago tele i mea fa'aopoopo.
5. Fa'agaioiina ma le Tulaga Lelei
Lu'i:O mea e fa'atumu maualuga ma mea fa'aopoopo e mafai ona o'o atu ai i le fa'auma leaga o luga, mamate drool, ma le fa'aoso fa'aletonu, lea e a'afia ai foliga ma le fa'atinoga o le oloa mulimuli uaea.
Tali:Fa'aogaSILIKE silicone Pa'u LYSI-100A. Leneifa'aopoopoga fa'avae siliconee fa'aaogaina lautele e pei o selubricant lelei fa'aopoopo fa'aopoopomo PVC-compatible resin systems e faʻaleleia ai le gaosiga o meatotino ma le lelei o luga. E pei o le sili atu o le resin flowability, faʻatumu faʻatumu & faʻasaʻo, faʻaitiitia le faʻamaʻi faʻamaʻi, ma le maualalo o le faʻaogaina o le feteʻenaʻiga, sili atu le maa, ma le abrasion teteʻe ...
Fa'amanuiaga Autu ole Silicon Powder LYSI-100A mo fa'aputuga PVC ma fa'aoga oloa mulimuli:
1) Low asu PVC uaea ma uaea tuufaatasia: extrusion mautu, itiiti mamafa mamafa, luga lamolemole o le uaea & uaea.
2) Low friction uaea PVC ma uaea: Low Coefficient o Friction, lagona lamolemole umi.
3) Poloaiga PVC e tete'e masi'i: Anti-scratch, pei o tapuni PVC.
4) PVC faʻamatalaga: sili atu le faʻatumuina o le faʻatumu ma le faʻasaʻoina o le limu, leai se moli moli.
5) PVC paipa: saoasaoa extrusion saoasaoa, faaitiitia COF, faaleleia luga lamolemole, ma sefe tau.
Afai o lo'o e feagai ma lu'itau ile fa'aogaina o le PVC ma fa'aletonu i luga ole laiga, po'o le tauivi ma le uaea PVC ma le uaea e maualalo le asu, taumafaiLYSI-100A Silicone Powder mo le faʻafefeteina ma sili atu le lelei.
