Makero eSilane-crosslinked polyethylene (XLPE) cable compounds rudzi rwethermoset insulation inoshandiswa mumagetsi. Anogadzirwa nemakero epolyethylene anobatanidza makemikari achishandisa silane compounds, ayo anoshandura chimiro chemolecular chepolyethylene kuita network ine mativi matatu. Maitiro aya anowedzera kugadzikana kwekupisa kwechinhu ichi, simba remakanika, uye hunhu hwemagetsi, zvichiita kuti chikwanise kushandiswa kwakasiyana-siyana, kubva pakutumira simba remagetsi rakaderera kusvika kune rakakwirira kuenda kumasisitimu emotokari.

Kugadzirisa matambudziko nemhinduro dzezvinhu zvesimbi zve XLPE zvine crosslinked silane

Kugadzirwa kwezvinhu zvakagadzirwa netambo ye silane-crosslinked polyethylene (XLPE) kunosangana nematambudziko makuru ehunyanzvi, anosanganisira kudzora pre-crosslinkage control, thermal shrinkage optimization, crystallinity adjustment, uye process stability. Kufambira mberi munguva pfupi yapfuura mu science yezvinhu uye nzira dzekugadzira kuri kugadzirisa matambudziko aya, zvichivandudza zvikuru kunaka kwechigadzirwa uye kugadzirwa kwegoho.

1. Kuderedza Kubatana Kusati Kwasangana uye Kupisa

 Dambudziko:Mukuita kweSioplas, kusvibiswa kwehunyoro panguva yekusanganisa uye kubudiswa kweZvikamu A neB kunogona kukonzera hydrolysis isati yasvika uye condensation reactions. Izvi zvinotungamira kukusadzoreka kusingadzoreki pre-crosslinking, zvichikonzera kunyunguduka kwakanyanya, kusafamba zvakanaka kwemvura, nzvimbo dzakaomarara, uye kudzikamisa insulation properties senge kudzikira kwevoltage.

Mhinduro:

Kubatanidzwa kweLubricant Additive:Kubatanidzamabheti makuru akavakirwa pasilicone, zvakaita seChinowedzera kugadzirwa kwesilicone chaSILIKELYPA-208C, inovandudza kufamba kwemvura inonyunguduka, inoderedza kunamira kwekunyunguduka pa screws uye ma dies, uye inodzivirira zvinobudirira pre-crosslinking pasina kukanganisa kunaka kwekupedzisira kwe crosslinking.

Silicone inowedzera LYPA-208Cine simba rakasimba rekudzivirira kubatanidzwa kwese kwese pasina kukanganisa kunaka kwekubatanidzwa kwese kwese.

Silicone masterbatch LYPA-208C inobvisa zvikanganiso zvepadenga zvakaita se "shark skin" uye inowedzera kutsvedzerera kwepadenga

Chinhu chinowedzera kubva kusilicone LYPA-208C chinoderedza zvakanyanya torque ye extrusion uye chinodzivirira kuwandisa kwemota

Zvimwe zveSiloxane LYPA-208Cinowedzera kugadzikana kwemutsetse we extrusion uye mwero wekubuda

Kugadzirisa Kupisa Kwegirinhi:Kushandisa tembiricha yebharero re extrusion rakapatsanurwa pakati pe140°C ne180°C kunobatsira kuderedza kupisa kwakanyanya munzvimbo yacho. Kuderedza nguva yekugara munzvimbo dzine tembiricha yepamusoro kunoderedzawo njodzi yekubatanidza zvinhu nguva isati yakwana.

Kugadziriswa Kwematanho Maviri:Kushandisa nzira ine matanho maviri, apo silane inonamirwa pa polyethylene isati yaburitswa, kunoderedza kumanikidzwa kunokonzerwa nekubatanidza mumutsara, nokudaro zvichideredza mukana wekubatanidza usati watanga kusanganisa panguva yekubvisa zvichienzaniswa nematanho ekuita chimwe chete.

2. Kugadzirisa Kushanda Kwekupisa Kwekupisa

Dambudziko:Kudzikira kwakanyanya kwechikamu chekudzivirira kunodzivirira kunokanganisa kushanduka kwechimiro uye kutadza kushanda kwemagetsi, zvakabatana nekutarisa kwekristaro uye kutonhora.

Mhinduro:

Masisitimu Ekutonhodza Ane Matanho Akawanda:Kushandisa nzira dzakasiyana-siyana dzekutonhodza mvura inopisa, inodziya, uye inotonhora kunoderedza mwero wekristaro, zvichibatsira kudzora kupisa uye kuderedza kuderera kwemvura.

Kugadziriswa kweParamende yeExtrusion: Kushandisa ma extruder ehurefu hwakareba kusvika padhayamita (≥30:1) kunowedzera nguva yekuchengetedza kunyunguduka, zvichideredza kugadzika kwekristaro kusingadiwe. Kushandisa compression kunoderedza kugadzika kwekristaro kunokonzerwa nekutarisa, zvichiwedzera kudzora kuderera.

Kusarudzwa Kwezvinhu:Kushandisa polyethylene ine nhanho mbiri ye silane-crosslinked kunobvumira kudzora kwakanyanya maitiro ekugadzira makristaro, zvichibatsira mukuvandudza kugadzikana kwekupisa.

3. Kuenzanisa Hunhu hweKristaro neHunhu hweMichina

Dambudziko:Kukora kwakanyanya kunokonzera kupfava, nepo kusakwana kwekristaro kunoderedza kuramba kupisa.

Mhinduro:

Kudzora Kupisa Kunonyunguduka:Kukwidza tembiricha yekunyunguduka kusvika 190°C–210°C nekugara kwenguva refu kunoderedza crystal nucleation, kunyange hazvo kutarisira kwakanyatsonaka kuchidikanwa kudzivirira kusangana panguva isati yakwana.

Dhizaini yeCatalyst Masterbatch:Kushandisa extrusion ine masikuruu maviri kunoita kuti organotin catalysts ipararire zvakaenzana, zvichiita kuti kubatana pakati pe crosslinking ne crystallinity zviwedzere kunaka kwemuchina.

4. Kuvandudza Kugadzikana Kwemaitiro

Dambudziko:Kunzwa kushanduka-shanduka kwemaitiro kunokonzera kusagadzikana kwekumanikidzwa kwekunze uye zvikanganiso pamusoro.

Mhinduro:

Kuvandudzwa kweMidziyo:Kushandisa masisitimu ekusanganisa madhiramu ane makoni maviri kunoita kuti zvive nyore kupararira kwezvinowedzerwa zvesilane, uye nguva yekusanganisa inodarika maawa 2.5 kuti pave nekuenderana kwakakwana.

Kutarisa Nguva Chaiyo:Kugara uchitarisa simba re screw current uye kumhanya kwekutenderera kunoita kuti pave nekugadzirisa tembiricha nekukurumidza uye nzira dzekuchenesa mold, zvichiita kuti pave nemamiriro ekugadzirisa akagadzikana.

Mafambiro Eindasitiri uye Maonero Eramangwana Ekugadzira tambo dzeXLPE

Kubatanidzwa kwekugadzirisa zvinhu zvine matanho maviri pamwe chete nezvimwe zvinowedzerwa zvinoshanda, zvakaita se silicone-based masterbatches, kwave nzira inotungamira yekukunda matambudziko ekugadzirisa zvinhu mukugadzira tambo dze XLPE. Zvitsva izvi zvinonzi zvawedzera goho rekugadzira neanopfuura 10~20% mumashandisirwo ekutanga, zvichiwedzera kuvimbika kwetambo dze XLPE muzvikamu zvemagetsi nemotokari. Tichitarisa mberi, vagadziri vari kutarisa pakutsvaga nekuvandudza matekinoroji ekutonhodza anochinjika uye kudzora maitiro ekuchenjera kuti vawedzere kunatsiridza mashandiro enyaya dze XLPE, zvichizadzisa kudiwa kuri kukura kwetambo dzinoshanda zvakanyanya.

Nekugamuchira nzira idzi dzepamusoro dzekugadzirisa zvinhu uye hunyanzvi hwezvinhu zvitsva, vagadziri vanogona kuwedzera zvakanyanya kushanda zvakanaka uye mhando yekugadzirwa kwetambo dzeXLPE, vachivimbisa kuti zvigadzirwa zvepamusoro zvinosangana nezvinodiwa zvemazuva ano zvemagetsi.
