Intshayelelo yocingo lwePVC oluphantsi lomsi kunye neeCompounds zeCable

Umsi ophantsi wePVC (i-Polyvinyl Chloride) ucingo kunye neekhompawundi zentambo zizinto ezikhethekileyo ze-thermoplastic izinto ezenzelwe ukunciphisa umsi kunye nokukhutshwa kwegesi eyityhefu ngexesha lokutsha. Oku kubenza ukhetho olubalulekileyo kwizicelo apho ukhuseleko lomlilo luphambili. Ngokuqhelekileyo isetyenziselwa ukugquma kunye nokufaka ibhatyi kwiintambo zombane, ezi khompawundi zibonelela ngezinto ezininzi eziphambili:

Ukuqulunqwa:Iikhompawundi zePVC zomsi ophantsi zenziwe ngokudityaniswa kwe-PVC resin, iiplasticizers (ezifana ne-dioctyl phthalate kunye ne-tri-2-ethylhexyl trimellitate), i-flame retardants (umz., i-antimony trioxide, i-aluminium trihydrate, kunye ne-zinc borate), i-stabilizers (i-calcium / i-zinc-based), izithambiso (i-calcium carbonate), kunye ne-lubricants carbonate.

Iinkcazelo Ngeempawu Zomsi Ophantsi:Ngokungafaniyo ne-PVC eqhelekileyo, enokunciphisa ukubonakala ukuya kuthi ga kwi-90% kwimizuzu engama-30 nje ngenxa yomsi oshinyeneyo, iikhompawundi zomsi eziphantsi zePVC zenzelwe ukuhlangabezana nemigangatho yokhuseleko efana ne-BS EN 61034. Ezi zixhobo zivumela ubuncinane i-60% yokuhambisa ukukhanya ngexesha lokutsha, ukuphucula kakhulu ukhuseleko.

Ukubuyiswa komlilo: I-PVC ngokwendalo ineempawu zokunqanda amadangatye ngenxa yesiqulatho sayo seklorini, eyongezelelwayo ngezongezo zedangatye ezongezelelweyo. Ezi zixhobo zihlangabezana nemigangatho engqongqo efana ne-IEC 60332-1-2, UL VW1, kunye ne-E84 (isalathisi sokusasazeka kwe-flame <25, isalathisi esiphuhliswe ngumsi <50).

 Usetyenziso:Idla ngokusetyenziswa kwiindawo ezinomngcipheko ophezulu njengamaziko edatha, itonela, iinqwelomoya, iikhareji zikaloliwe, kunye nezakhiwo zikawonke-wonke, ucingo lwePVC lomsi ophantsi kunye neekhompawundi zentambo zibalulekile ekunciphiseni ubungozi obunxulumene nomsi kunye nomsi oyityhefu xa kunokutsha.

Imicelimngeni yokuCwangciswa okuQhelekileyo kunye nezisombululo zocingo lwePVC oluphantsi lomsi kunye neeCompounds zeCable

Ukucutshungulwa komsi ophantsi we-PVC iikhompawundi kubandakanya ukulawula uluhlu lwemingeni, ngakumbi ngenxa yokuqulunqwa kwayo okuyinkimbinkimbi. Apha ngezantsi, sixoxa ngeminye yemiba eqhelekileyo yokusetyenzwa kunye nezisombululo zayo:

1. Isiqulatho soMgcwalisi oPhakamileyo oKhokela ukuHamba okuNgalunganga kunye neTorque ephezulu

Umngeni:Ukufezekisa iipropati zomsi ophantsi, iikhompawundi ze-PVC zihlala ziqulethe amanqanaba aphezulu e-inorganic fillers njenge-aluminium trihydrate (ATH) okanye i-magnesium hydroxide (Mg (OH) ₂) - ngokuqhelekileyo i-20-60% ngobunzima. Ngelixa ezi zihluzi zinciphisa umsi kunye nedangatye, zinokunyusa i-viscosity, zinciphise ukuhamba, kwaye zibangele ukunxiba kwezixhobo.

Izisombululo:

Dibanisa izixhobo zokusebenza ezifana nezithambiso zangaphakathi/zangaphandle (umzekelo, icalcium stearate, ipolyethylene wax, okanyeizongezo ze-silicone) kwi-0.5-2.0 phr ukunciphisa i-viscosity kunye nokuphucula ukuhamba.

Sebenzisa umlinganiselo ophezulu we-L/D we-twin-screw extruders ukuphucula ukuxuba kunye nokuchithwa kwe-filler.

Sebenzisa iisistim ze-kneader ezine-conical force feed ukuqinisekisa ukudibanisa okufanayo.

Khetha iifayili ezinobungakanani obulawulwayo kunye nonyango lomphezulu ukuphucula ukuhambelana nokunciphisa i-abrasion.

2. Ukuzinza kweThermal

Umngeni:I-PVC inokunciphisa ngexesha lokucubungula, ngokukodwa ngokugcwalisa okuphezulu kunye nemithwalo ye-flame-retardant, ikhupha i-hydrogen chloride (HCl) igesi ekhokelela ekuthotyweni kwezinto, ukubola, kunye nokubola kwezixhobo.

Izisombululo:

Yongeza i-stabilizers yokushisa njenge-calcium / i-zinc-based stabilizers kwi-2-4 phr ukuze unciphise i-HCl kunye nokukhusela ukuthotywa.

Sebenzisa i-oyile ye-soy epoxidized (ESO) njenge-co-stabilizer yokuphucula i-thermal kunye ne-photo-stability.

Lawula ukusetyenzwa kwamaqondo ngokuchanekileyo (160-190 ° C) ukuphepha ukushisa.

Bandakanya i-phenolic antioxidants (umzekelo, i-Bisphenol A kwi-0.3-0.5%) ukunyusa ukuchasana nokuguga ngexesha lokucubungula.

3. Ukufuduka kwePlastiki

Umngeni:Iiplastiki ezisetyenziselwa ukuphucula ukuguquguquka zinokufuduka phantsi kobushushu obuphezulu (umzekelo, kumaziko edatha), okukhokelela ekwakhekeni kwentsalela enokuphazamisa ukuhanjiswa komqondiso okanye ukunciphisa ubude bekhebula.

Izisombululo:

Sebenzisa iiplastiki zepolymeric ezingafudukiyo endaweni yee-monomeric (umzekelo, i-DOP, i-DINP) ukunciphisa ukufuduka.

Phuhlisa iifomyula ze-plenum "ezingenalwelo", njengoko zivulwe yi-OTECH, ukuthintela ukufuduka kweplastiki kwindawo yobushushu obuphezulu.

Khetha i-plasticizers efana ne-TOTM, ene-volatility ephantsi kwaye ifaneleke ngakumbi kwizicelo eziphezulu zokushisa.

4. Ukulungelelaniswa kweFrime Retardancy kunye nokuNcitshiswa koMsi

Umngeni:Ukonyusa ukusilela komlilo ngokusebenzisa izongezo ezifana ne-antimony trioxide (3-5%) okanye iikhompawundi zebrominated (12-15%) zinokunyusa ukukhutshwa komsi, nto leyo eyenza kube nzima ukulinganisa iipropati zombini. Ngokufanayo, izigcwalisi ezifana ne-calcium carbonate zinokunciphisa umsi kodwa zisehlisa isalathisi se-oksijini, ezichaphazela ukubuyiswa komlilo.

Izisombululo:

Sebenzisa indibaniselwano ye-synergistic ye-flame retardant (umzekelo, i-ATH ene-zinc borate) ukwandisa ukubuyiswa komlilo kunye nokucutha umsi. Ngokomzekelo, i-ATH, ikhupha umphunga wamanzi ukuphazamisa ukutsha kwaye yenze i-char layer ekhuselayo, enciphisa umsi.

Nciphisa ukulayisha kweCaCO₃ ukuya kwi-20-40 phr ukubetha ibhalansi phakathi kweendleko, ukunyanzeliswa komsi, kunye nokubuyiswa komlilo, njengoko izixa ezigqithisileyo zinokunciphisa isalathisi se-oxygen.

Phonononga imixube yePVC eqhagamsheleneyo, efana nePVC edityaniswe ngemitha enqamlezileyo, ukuqinisa ukulibaziseka komlilo ngaphandle kokuxhomekeka kakhulu kwizongezo zehalogenated.

5. Ukuqhubekeka kunye noMgangatho woMphezulu

Umngeni:Ukuzaliswa okuphezulu kunye nomxholo owongezelelweyo kunokukhokelela ekugqityweni komgangatho ophantsi, ukufa kwe-drool, kunye ne-extrusion engahambelaniyo, echaphazela ukubonakala kunye nokusebenza kwemveliso yentambo yokugqibela.

Izisombululo:SebenzisaSILIKE abicah Powder LYSI-100A. Okui-silicone-based additiveisetyenziswa ngokubanzi njengei-lubricant processing esebenzayo isongezokwiinkqubo PVC-ehambelanayo resin ukuphucula iimpawu processing kunye nomgangatho womphezulu. Okufana nokuhamba ngcono kwe-resin, ukuzaliswa komngundo kunye nokukhululwa, i-torque encinci ye-extruder, kunye ne-coefficient ephantsi ye-friction, i-mar enkulu, kunye nokuchasana kwe-abrasion ...

Izibonelelo eziphambili ze-silicone Powder LYSI-100A kwiikhompawundi zePVC kunye nokusetyenziswa kwemveliso yokugqibela:

1) Umsi ophantsi wePVC ucingo kunye neekhompawundi zentambo: i-extrusion ezinzileyo, uxinzelelo oluphantsi lokufa, indawo egudileyo yocingo kunye nentambo.

2) I-Friction ephantsi ye-PVC ucingo kunye nentambo: I-Coefficient ephantsi ye-Friction, imvakalelo egudileyo ehlala ixesha elide.

3) Imveliso yePVC enganyangekiyo: Anti-scratch, njengakwizivalo zePVC.

I-4) Iiprofayili ze-PVC: ukuzaliswa kwe-mold engcono kunye nokukhululwa kwe-mold, akukho flash flash.

5) Umbhobho wePVC: isantya sokukhupha ngokukhawuleza, ukunciphisa i-COF, ukuguda komhlaba okuphuculweyo, kunye neendleko ezigciniweyo.

Ukuba ujongene nemiceli mngeni nge-PVC yokusetyenzwa kwekhompawundi kunye neziphene zomphezulu, okanye unengxaki yocingo oluphantsi lomsi wePVC kunye nokulungiswa kwentambo, zama.I-LYSI-100A ye-Silicone Powder yokukhupha okugudileyo kunye nokusebenza okuphezulu.
