Chiyambi cha Waya Wotsika wa PVC ndi Ma Cable Compounds

Waya wa PVC (Polyvinyl Chloride) wa utsi wochepa (Polyvinyl Chloride) ndi zida zapadera zopangira thermoplastic zomwe zimapangidwira kuchepetsa utsi ndi mpweya wapoizoni pakuyaka. Izi zimawapangitsa kukhala kusankha kofunikira pamapulogalamu omwe chitetezo chamoto chimakhala chofunikira kwambiri. Zomwe zimagwiritsidwa ntchito pakutchinjiriza ndi kuyika jekete mu zingwe zamagetsi, mankhwalawa amapereka zinthu zingapo zofunika:

Zolemba:Utsi wochepa wa PVC umapangidwa ndi kuphatikiza PVC utomoni, plasticizers (monga dioctyl phthalate ndi tri-2-ethylhexyl trimellitate), retardants malawi (mwachitsanzo, antimony trioxide, aluminium trihydrate, ndi zinki borate), stabilizers (calcium/zinki-based), fillers (calcium carbonate), ndi lubricants.

Katundu Wotsika Utsi:Mosiyana ndi PVC yokhazikika, yomwe ingachepetse kuwonekera mpaka 90% mu mphindi 30 zokha chifukwa cha utsi wandiweyani, utsi wochepa wa PVC umapangidwa kuti ukwaniritse miyezo ya chitetezo monga BS EN 61034. Mankhwalawa amalola kuti osachepera 60% apereke kuwala pa kuyaka, kuwongolera kwambiri chitetezo.

Kuchedwa kwa Flame: PVC mwachibadwa imakhala ndi mphamvu yoletsa moto chifukwa cha klorini, yomwe imapangidwanso ndi zowonjezera zowonjezera moto. Mankhwalawa amakwaniritsa miyezo yolimba monga IEC 60332-1-2, UL VW1, ndi E84 (chilolezo chofalikira chamoto <25, index yopangidwa ndi utsi <50).

 Mapulogalamu:Zomwe zimagwiritsidwa ntchito m'malo owopsa kwambiri monga malo opangira data, tunnel, ndege, zonyamula njanji, ndi nyumba zapagulu, mawaya a PVC a utsi wochepa ndi zida za chingwe ndizofunikira kwambiri kuti muchepetse kuopsa kwa utsi ndi utsi wapoizoni ukayaka moto.

Common Processing Challenges and Solutions for Low Utsi PVC Waya ndi Cable Compounds

Kukonza utsi wochepa wa PVC mankhwala kumaphatikizapo kuyang'anira zovuta zosiyanasiyana, makamaka chifukwa cha mapangidwe awo ovuta. Pansipa, tikambirana zina mwazofala kwambiri pakukonza ndi mayankho awo:

1. Zodzaza Kwambiri Zomwe Zimatsogolera Kusayenda Bwino ndi Torque Yapamwamba

Chovuta:Kuti mukwaniritse utsi wochepa, mankhwala a PVC nthawi zambiri amakhala ndi ma inorganic fillers monga aluminium trihydrate (ATH) kapena magnesium hydroxide (Mg(OH) ₂) - nthawi zambiri 20-60% kulemera kwake. Ngakhale zodzaza izi zimachepetsa utsi ndi moto, zimatha kuwonjezera kukhuthala, kuchepetsa kuyenda, ndikupangitsa zida kuvala.

Zothetsera:

Phatikizani zinthu zopangira mafuta monga zothira zamkati/zakunja (mwachitsanzo, calcium stearate, phula la polyethylene, kapenazowonjezera za silicone) pa 0.5-2.0 phr kuti muchepetse kukhuthala komanso kupititsa patsogolo kuyenda.

Gwiritsani ntchito ma extruder apamwamba a L/D kuti muwonjezere kusakanikirana ndi kubalalitsa.

Gwiritsani ntchito makina ophatikizira omwe ali ndi conical force feed kuti awonetsetse kuti akuphatikizana.

Sankhani ma fillers okhala ndi kukula kwa tinthu kolamulidwa ndi mankhwala apamtunda kuti mugwirizane ndikuchepetsa ma abrasion.

2. Kukhazikika kwa kutentha

Chovuta:PVC imatha kuonongeka panthawi yokonza, makamaka ndi katundu wodzaza kwambiri komanso woletsa moto, kutulutsa mpweya wa hydrogen chloride (HCl) womwe umabweretsa kuwonongeka kwa zinthu, kusinthika, komanso kuwonongeka kwa zida.

Zothetsera:

Onjezani zowonjezera kutentha monga calcium / zinc-based stabilizers pa 2-4 phr kuti muchepetse HCl ndikupewa kuwonongeka.

Gwiritsani ntchito epoxidized soya mafuta (ESO) ngati co-stabilizer kuti muzitha kutentha komanso kukhazikika kwazithunzi.

Yang'anirani kutentha kwa kutentha (160-190 ° C) kuti musatenthedwe.

Phatikizani phenolic antioxidants (mwachitsanzo, Bisphenol A pa 0.3-0.5%) kuti muwonjezere kukana kukalamba panthawi yokonza.

3. Plasticizer Migration

Chovuta:Mapulastiki omwe amagwiritsidwa ntchito kuti azitha kusinthasintha amatha kusuntha kutentha kwakukulu (mwachitsanzo, kumalo osungiramo deta), zomwe zimapangitsa kuti zotsalira zikhale zotsalira zomwe zingasokoneze kutumiza ma siginecha kapena kuchepetsa moyo wautali wa chingwe.

Zothetsera:

Gwiritsani ntchito mapulasitiki a polymeric osasuntha m'malo mwa monomeric (mwachitsanzo, DOP, DINP) kuti muchepetse kusamuka.

Pangani ma formula a "no-liquid" plenum, monga momwe adachitira upainiya ndi OTECH, kuti mupewe kusamuka kwa plasticizer m'malo otentha kwambiri.

Sankhani ma plasticizers ngati TOTM, omwe ali ndi kusinthasintha kochepa komanso oyenera kwambiri kutentha kwambiri.

4. Kulinganiza Kuchedwa kwa Flame ndi Kuletsa Utsi

Chovuta:Kuchulukitsa kuchedwa kwa malawi kudzera mu zowonjezera monga antimony trioxide (3-5%) kapena mankhwala a brominated (12-15%) kumatha kukulitsa utsi, zomwe zimapangitsa kuti zikhale zovuta kulinganiza zinthu zonse ziwiri. Mofananamo, zodzaza ngati calcium carbonate zimatha kuchepetsa utsi koma zimatha kutsitsa index ya okosijeni, zomwe zimakhudza kuchedwa kwa malawi.

Zothetsera:

Gwiritsani ntchito zosakaniza zoletsa moto (monga ATH yokhala ndi zinki borate) kuti muchepetse kuchedwa kwa malawi komanso kuletsa utsi. Mwachitsanzo, ATH imatulutsa mpweya wamadzi kuti usokoneze kuyaka ndikupanga chiwombankhanga choteteza, chomwe chimachepetsa utsi.

Chepetsani kukweza kwa CaCO₃ ku 20-40 phr kuti muchepetse mtengo, kuponderezana ndi utsi, ndi kuchedwa kwa lawi lamoto, chifukwa kuchuluka kwambiri kumatha kuchepetsa index ya okosijeni.

Onani mawonekedwe a PVC olumikizirana, monga PVC yolumikizidwa ndi ma radiation, kuti muwonjezere kuchedwa kwa lawi popanda kudalira kwambiri zowonjezera za halogenated.

5. Processability ndi pamwamba Quality

Chovuta:Zodzaza kwambiri komanso zowonjezera zimatha kubweretsa kutsika koyipa, kufa drool, ndi kutulutsa kosagwirizana, komwe kumakhudza mawonekedwe ndi magwiridwe antchito a chingwe chomaliza.

Zothetsera:Gwiritsani ntchitoSILIKE silikoni ufa LYSI-100A. Izisilicon-based zowonjezeraamagwiritsidwa ntchito kwambiri ngatiimayenera lubricant processing zowonjezerakwa machitidwe PVC-n'zogwirizana utomoni kusintha katundu processing ndi pamwamba khalidwe. Monga kuyenda bwino kwa utomoni, kudzaza nkhungu & kumasula, torque yocheperako, komanso kukangana kocheperako, kukana kwakukulu, komanso kukana abrasion…

Ubwino Wambiri wa Silicone Powder LYSI-100A pamagulu a PVC ndi kugwiritsa ntchito komaliza:

1) Low utsi PVC waya ndi mankhwala chingwe: extrusion khola, zochepa kufa kuthamanga, yosalala pamwamba pa waya & chingwe.

2) Waya wa PVC wa waya ndi chingwe chotsika: Coefficient yotsika ya Friction, kumverera kosalala kwanthawi yayitali.

3) PVC yosagwira ntchito: Anti-scratch, ngati zotsekera za PVC.

4) Mbiri ya PVC: kudzaza bwino kwa nkhungu ndikutulutsa nkhungu, palibe kung'anima kwa nkhungu.

5) PVC chitoliro: mofulumira extrusion liwiro, yafupika COF, bwino pamwamba kusalala, ndi mtengo opulumutsidwa.

Ngati mukukumana ndi zovuta ndi kukonza kwa PVC pawiri ndi zolakwika zapamtunda, kapena mukulimbana ndi waya wotsikirapo wa PVC ndi kukonza chingwe, yesani.LYSI-100A Silicone Powder yotulutsa bwino komanso kuchita bwino kwambiri.
