Nhanganyaya kune Yakaderera Chiutsi PVC Wire uye Cable Compounds

Utsi hwepasi PVC (Polyvinyl Chloride) waya nemakomisheni etambo zvinhu zvine hunyanzvi zve thermoplastic zvakagadzirirwa kuderedza utsi uye kuburitsa gasi rine muchetura panguva yekupisa. Izvi zvinovaita sarudzo yakakosha yezvikumbiro uko kuchengetedza moto kuri pamberi. Inowanzo shandiswa kuvharisa uye jekete mumatambo emagetsi, makomisheni aya anopa akati wandei akakosha maficha:

Kuumbwa:Utsi hwepasi PVC macompounds anogadzirwa nemusanganiswa wePVC resin, plasticizers (senge dioctyl phthalate uye tri-2-ethylhexyl trimellitate), zvinodzoreredza moto (semuenzaniso, antimony trioxide, aluminium trihydrate, uye zinc borate), stabilizers (calcium/zinc-based), fillers (calcium carbonate), uye lubricants.

Low Smoke Properties:Kusiyana nePVC yakajairwa, iyo inogona kuderedza kuoneka kusvika ku90% mumaminitsi makumi matatu chete nekuda kwehutsi hwakanyanya, hutsi hushoma hwePVC hunogadzirwa kuti huenderane nemitemo yekuchengeteka yakadai seBS EN 61034. Mishonga iyi inobvumira zvishoma 60% transmittance yechiedza panguva yekupisa, inovandudza zvikuru kuchengetedza.

Flame Retardancy: PVC ine hunhu hunodzoreredza moto nekuda kweiyo chlorine yemukati, iyo inowedzerwa nekuwedzera murazvo retardant additives. Mishonga iyi inosangana nemiyero yakaoma seIEC 60332-1-2, UL VW1, uye E84 (flame spread spread index <25, smoke made index <50).

 Applications:Inowanzoshandiswa munzvimbo dzine njodzi dzakadai senzvimbo dzedata, tunnels, ndege, ngoro dzenjanji, uye zvivakwa zveveruzhinji, waya yePVC yehutsi shoma nemakomponi etambo zvakakosha mukuderedza njodzi dzine chekuita nehutsi nehutsi hunokachidza kana moto ukabvira.

Zvakajairwa Kugadzirisa Zvinetso uye Mhinduro dzeYakaderera Chiutsi PVC Wire uye Cable Compounds

Kugadzira pasi peutsi PVC makomisheni anosanganisira kugadzirisa huwandu hwezvinetso, kunyanya nekuda kwekuoma kwavo kugadzira. Pazasi, isu tinokurukura dzimwe dzeakajairika kugadzirisa nyaya uye mhinduro dzadzo:

1. Yepamusoro Filler Content Inotungamira kune Yakashata Mobility uye Yakakwira Torque

Dambudziko:Kuti uwane hutsi hwehutsi hwehutsi, PVC makomisheni anowanzo kuve neakakwira mazinga easingagadzike mafirita sealuminum trihydrate (ATH) kana magnesium hydroxide (Mg(OH) ₂) - kazhinji 20-60% nehuremu. Nepo aya mafirita achideredza utsi nemurazvo, anogona kuwedzera viscosity, kuderedza kuyerera, uye kukonzera kupfeka kwemidziyo.

Mhinduro:

Batanidza zvinoyamura kugadzira semafuta emukati / ekunze (semuenzaniso, calcium stearate, polyethylene wax, kanasilicone additives) pa 0.5-2.0 phr kuderedza viscosity uye kuwedzera kuyerera.

Shandisa yakakwira L/D reshiyo mapatya-screw extruders kuvandudza kusanganisa uye kuparadzira kwekuzadza.

Shandisa kneader masisitimu ane conical simba rekudya kuti ive nechokwadi chekubatanidza yunifomu.

Sarudza mafirita ane akadzora particle saizi uye epamusoro marapirwo kuvandudza kuenderana uye kuderedza abrasion.

2. Thermal Kugadzikana

Dambudziko:PVC inogona kushatisa panguva yekugadziriswa, kunyanya nemafuta akakwira uye anodzoreredza moto, achiburitsa hydrogen chloride (HCl) gasi rinotungamira mukuparara kwezvinhu, kushanduka kwemavara, uye kuparara kwemidziyo.

Mhinduro:

Wedzera kupisa kunopisa senge calcium / zinc-based stabilizers pa 2-4 phr kuderedza HCl uye kudzivirira kuparara.

Shandisa epoxidized soybean oil (ESO) seyakagadzikana-stabilizer yekuvandudza kupisa uye kugadzikana kwemafoto.

Dzora kupisa tembiricha nenzira kwayo (160-190 ° C) kudzivirira kupisa.

Sanganisira phenolic antioxidants (semuenzaniso, Bisphenol A pa 0.3-0.5%) kuwedzera kuchembera kuramba panguva yekugadzirisa.

3. Plasticizer Migration

Dambudziko:Plasticizers anoshandiswa kuwedzera kuchinjika anogona kutama achipisa zvakanyanya (semuenzaniso, munzvimbo dzedata), zvichitungamira kune zvakasara kuvaka izvo zvinogona kukanganisa kutapurirana kwechiratidzo kana kuderedza hupenyu hurefu hwetambo.

Mhinduro:

Shandisa zvisiri-kutama-polymeric plasticizers panzvimbo monomeric (eg, DOP, DINP) kuderedza kutama.

Gadzira "no-liquid" plenum formulas, sekupayona neOTECH, kudzivirira kutama kweplasticizer munzvimbo dzinopisa.

Sarudza mapurasitiki akaita seTOTM, ayo ane kuderera kwepasi uye akakodzera zvakanyanya-kupisa kwekushanda.

4. Kuenzanisa Flame Retardancy uye Smoke Suppression

Dambudziko:Kuwedzera kudzoserwa kwemoto kuburikidza nezvinowedzerwa senge antimony trioxide (3-5%) kana brominated compounds (12-15%) zvinogona kuwedzera kubuda kweutsi, zvichiita kuti zviome kuenzanisa zvivakwa zvese. Saizvozvo, mafirita senge calcium carbonate anogona kuderedza utsi asi anogona kudzikisa okisijeni index, zvichikanganisa kunonoka kwemurazvo.

Mhinduro:

Shandisa synergistic flame retardant misanganiswa (semuenzaniso, ATH ine zinc borate) kukwidziridza kunonoka kwemurazvo uye kudzvinyirira utsi. ATH, semuenzaniso, inoburitsa mhute yemvura kuti ivhiringidze kupisa uye igadzire chinodzivirira char layer, chinoderedza utsi.

Deredza iyo CaCO₃ kurodha ku20-40 phr kurova chiyero pakati pemutengo, kudzvinyirira utsi, uye kudzoreredza murazvo, sezvo huwandu hwakawandisa hunogona kuderedza iyo oksijeni index.

Ongorora maumbirwo ePVC anochinjika, akadai semwaranzi muchinjiko-yakabatana PVC, kuti uwedzere kunonoka kwemurazvo pasina kuvimba zvakanyanya pane zvinowedzerwa zvine halogenated.

5. Processability uye Surface Quality

Dambudziko:Yakakwira mafirita uye ekuwedzera emukati anogona kutungamira kune kushomeka kwepamusoro kupera, kufa drool, uye kusawirirana extrusion, iyo inokanganisa kutaridzika uye kuita kweyekupedzisira tambo chigadzirwa.

Solutions:ShandisaSILIKE silicone Powder LYSI-100A. Izvisilicone-based additiveinoshandiswa zvakanyanya seinoshanda lubricant processing additiveyePVC-inoenderana resin masisitimu ekuvandudza zvivakwa zvekugadzirisa uye pamusoro pemhando. Zvakadai sezviri nani resin kuyerera, kuzadza mold & kuburitsa, shoma extruder torque, uye yakaderera coefficient yekukwesha, yakakura mar, uye abrasion kuramba ...

Mabhenefiti Akakosha esilicone Powder LYSI-100A yePVC makomputa uye yekupedzisira chigadzirwa maapplication:

1) Yakaderera chiutsi PVC waya uye tambo komputa: yakagadzikana extrusion, kushoma kufa kumanikidza, yakatsetseka pamusoro pewaya & tambo.

2) Low friction PVC waya uye tambo: Yakaderera Coefficient yeFriction, inogara kwenguva refu yakatsetseka kunzwa.

3) Chigadzirwa chinodzivirira PVC: Anti-scratch, senge muPVC shutters.

4) PVC profiles: nani mold kuzadza uye mold kusunungurwa, hapana mold flash.

5) PVC pombi: kukurumidza extrusion kumhanya, yakaderedzwa COF, yakagadziridzwa pamusoro kutsvedzerera, uye yakachengetedzwa mutengo.

Kana uri kutarisana nezvipingamupinyi nePVC musanganiswa wekugadzirisa uye kuremara kwepamusoro, kana kunetseka newaya inopfungaira PVC uye kugadzira tambo, edza.LYSI-100A Silicone Powder yekunyorovesa extrusion uye yakanyanya kunaka.
