Chiyambi cha Waya wa PVC Wopanda Utsi ndi Ma Cable Compounds

Ma waya ndi ma waya a PVC (Polyvinyl Chloride) okhala ndi utsi wochepa ndi zinthu zapadera zopangidwa kuti zichepetse utsi ndi mpweya woipa panthawi yoyaka. Izi zimapangitsa kuti zikhale zofunika kwambiri pakugwiritsa ntchito komwe chitetezo cha moto chili patsogolo. Kawirikawiri amagwiritsidwa ntchito poteteza kutentha ndi kuphimba zingwe zamagetsi, zinthuzi zimakhala ndi zinthu zingapo zofunika:

Kapangidwe kake:Ma PVC okhala ndi utsi wochepa amapangidwa ndi kuphatikiza kwa PVC resin, ma plasticizer (monga dioctyl phthalate ndi tri-2-ethylhexyl trimellitate), zoletsa moto (monga antimony trioxide, aluminium trihydrate, ndi zinc borate), zokhazikika (zochokera ku calcium/zinc), zodzaza (calcium carbonate), ndi zodzola.

Utsi Wochepa:Mosiyana ndi PVC yokhazikika, yomwe imatha kuchepetsa kuwoneka bwino ndi 90% m'mphindi 30 zokha chifukwa cha utsi wambiri, mankhwala a PVC omwe ali ndi utsi wochepa amapangidwa kuti akwaniritse miyezo yachitetezo monga BS EN 61034. Mankhwalawa amalola kuwala kwa osachepera 60% panthawi yoyaka, zomwe zimapangitsa kuti chitetezo chikhale bwino.

Kubwerera kwa Moto: PVC mwachibadwa ili ndi mphamvu zoletsa moto chifukwa cha kuchuluka kwa chlorine, komwe kumawonjezeredwa ndi zowonjezera zowonjezera zoletsa moto. Mankhwalawa amakwaniritsa miyezo yokhwima monga IEC 60332-1-2, UL VW1, ndi E84 (flame spread index <25, smoke developed index <50).

 Mapulogalamu:Ma waya a PVC ndi ma waya a chingwe omwe amagwiritsidwa ntchito kwambiri m'malo omwe ali pachiwopsezo chachikulu monga malo osungira deta, ma tunnel, ndege, magaleta a sitima, ndi nyumba za anthu onse, ndi ofunikira kwambiri pochepetsa zoopsa zokhudzana ndi utsi ndi utsi woopsa pakagwa moto.

Mavuto Omwe Amakumana Nawo Pankhani Yokonza Zinthu ndi Mayankho Okhudzana ndi Waya wa PVC Wopanda Utsi ndi Ma Cable Compounds

Kukonza mankhwala a PVC omwe ali ndi utsi wochepa kumaphatikizapo kuthana ndi mavuto osiyanasiyana, makamaka chifukwa cha kapangidwe kake kovuta. Pansipa, tikambirana zina mwa mavuto omwe amafala kwambiri pokonza ndi mayankho ake:

1. Zinthu Zodzaza Kwambiri Zomwe Zimayambitsa Kusayenda Bwino ndi Mphamvu Yaikulu

Vuto:Kuti utsi ukhale wotsika, mankhwala a PVC nthawi zambiri amakhala ndi zinthu zambiri zosapangidwa monga aluminium trihydrate (ATH) kapena magnesium hydroxide (Mg(OH)₂) — nthawi zambiri zimakhala 20-60% polemera. Ngakhale kuti zinthuzi zimachepetsa utsi ndi lawi, zimatha kuwonjezera kukhuthala, kuchepetsa kuyenda kwa madzi, komanso kuyambitsa kuwonongeka kwa zida.

Mayankho:

Phatikizani zinthu zothandizira kukonza zinthu monga mafuta amkati/akunja (monga calcium stearate, ma polyethylene waxes, kapenazowonjezera za silikoni) pa 0.5-2.0 phr kuti muchepetse kukhuthala ndikuwonjezera kuyenda.

Gwiritsani ntchito zotulutsira zinthu ziwiri zokhala ndi chiŵerengero cha L/D kuti muwongolere kusakaniza ndi kufalikira kwa zinthu zodzaza.

Gwiritsani ntchito makina olumikizirana ndi makina olumikizirana kuti muwonetsetse kuti zinthu zikugwirizana.

Sankhani zodzaza ndi tinthu tating'onoting'ono tomwe timayang'aniridwa bwino komanso mankhwala ochizira pamwamba kuti zigwirizane bwino ndikuchepetsa kusweka.

2. Kukhazikika kwa Kutentha

Vuto:PVC imatha kuwonongeka ikakonzedwa, makamaka ndi zinthu zambiri zodzaza ndi zoletsa moto, kutulutsa mpweya wa hydrogen chloride (HCl) womwe umayambitsa kuwonongeka kwa zinthu, kusintha mtundu, ndi dzimbiri la zida.

Mayankho:

Onjezani zolimbitsa kutentha monga zolimbitsa thupi zochokera ku calcium/zinc pa 2-4 phr kuti muchepetse HCl ndikuletsa kuwonongeka.

Gwiritsani ntchito mafuta a soya opangidwa ndi epoxidized (ESO) ngati chokhazikika pamodzi kuti kutentha ndi kuwala zikhale bwino.

Sinthani kutentha kokonza bwino (160-190°C) kuti mupewe kutentha kwambiri.

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

3. Kusamutsa kwa Pulasitiki

Vuto:Mapulasitiki omwe amagwiritsidwa ntchito powonjezera kusinthasintha amatha kusuntha pansi pa kutentha kwakukulu (monga m'malo osungira deta), zomwe zimapangitsa kuti zinyalala zizisonkhana zomwe zingasokoneze kutumiza kwa chizindikiro kapena kuchepetsa nthawi yayitali ya chingwe.

Mayankho:

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

Pangani ma formula a plenum "opanda madzi", monga momwe OTECH idapangira, kuti mupewe kusamuka kwa pulasitiki m'malo otentha kwambiri.

Sankhani mapulasitiki monga TOTM, omwe sasinthasintha kwambiri ndipo ndi oyenera kugwiritsa ntchito kutentha kwambiri.

4. Kulinganiza Kuletsa Moto ndi Kuletsa Utsi

Vuto:Kuonjezera kuchedwa kwa moto kudzera mu zowonjezera monga antimony trioxide (3-5%) kapena mankhwala opangidwa ndi brominated (12-15%) kungawonjezere kutulutsa kwa utsi, zomwe zimapangitsa kuti zikhale zovuta kulinganiza bwino zinthu zonse ziwiri. Mofananamo, zodzaza monga calcium carbonate zimatha kuchepetsa utsi koma zimatha kuchepetsa index ya okosijeni, zomwe zimakhudza kuchedwa kwa moto.

Mayankho:

Gwiritsani ntchito kuphatikiza kogwirizana kwa zinthu zoletsa moto (monga ATH ndi zinc borate) kuti muwonjezere kuletsa moto komanso kuletsa utsi. Mwachitsanzo, ATH imatulutsa nthunzi ya madzi kuti isokoneze kuyaka ndikupanga choteteza cha char, chomwe chimachepetsa utsi.

Chepetsani kuchuluka kwa CaCO₃ kufika pa 20-40 phr kuti mupeze mgwirizano pakati pa mtengo, kuletsa utsi, ndi kuchedwa kwa moto, chifukwa kuchuluka kwambiri kungachepetse kuchuluka kwa mpweya m'thupi.

Fufuzani mitundu ya PVC yolumikizana, monga PVC yolumikizana ndi radiation, kuti muwonjezere kuchedwa kwa moto popanda kudalira kwambiri zowonjezera za halogenated.

5. Kuthekera Kogwirira Ntchito ndi Ubwino Wapamwamba

Vuto:Kudzaza kwambiri ndi zowonjezera kungayambitse kusakhala bwino kwa pamwamba, kutaya madzi, komanso kutulutsa kosasinthasintha, zomwe zimakhudza mawonekedwe ndi magwiridwe antchito a chingwe chomaliza.

Mayankho:Gwiritsani ntchitoUfa wa silikoni wa SILIKE LYSI-100AIzichowonjezera chochokera ku silikoniimagwiritsidwa ntchito kwambiri ngatichowonjezera chogwiritsira ntchito mafuta bwinoza makina a resin ogwirizana ndi PVC kuti akonze bwino momwe amagwirira ntchito komanso ubwino wa pamwamba pake. Monga kuyenda bwino kwa resin, kudzaza ndi kutulutsa nkhungu, mphamvu yochepa ya extruder, komanso kutsika kwa coefficient of friction, kukana kwa mar, ndi abrasion…

Ubwino Waukulu wa silicone Powder LYSI-100A pakupanga zinthu za PVC ndi ntchito zomaliza:

1) Ma waya a PVC ndi ma waya opanda utsi wambiri: kutulutsa kokhazikika, kupanikizika kochepa, pamwamba pa waya ndi chingwe chosalala.

2) Waya ndi chingwe cha PVC chocheperako: Chokwanira chochepa cha kukangana, kumva bwino kwa nthawi yayitali.

3) Chopangidwa ndi PVC chosakanda: Chosakanda, monga momwe zilili ndi zotsekera za PVC.

4) Mbiri za PVC: kudzaza bwino nkhungu ndi kutulutsa nkhungu, palibe kung'anima kwa nkhungu.

5) Chitoliro cha PVC: liwiro lotulutsa madzi mwachangu, COF yochepa, kusalala bwino kwa pamwamba, komanso kusunga ndalama.

Ngati mukukumana ndi mavuto ndi kukonza zinthu za PVC ndi zolakwika pamwamba, kapena mukuvutika ndi kukonza waya ndi chingwe cha PVC chomwe sichili ndi utsi wambiri, yesaniUfa wa Silicone wa LYSI-100A wothandiza kutulutsa zinthu mosalala komanso kugwira ntchito bwino.
