Metswako ya thapo ya polyethylene e hokahaneng le Silane (XLPE) ke mofuta wa ho kenya thermoset e sebediswang ka hara dithapo tsa motlakase. Di hlahiswa ke dimolekhule tsa polyethylene tse hokahanang ka dikhemikhale tse sebedisang metswako ya silane, e fetolang sebopeho sa molek'hule sa polyethylene hore e be marangrang a mahlakore a mararo. Tshebetso ena e ntlafatsa botsitso ba mocheso wa thepa, matla a mechini le thepa ya motlakase, e leng se etsang hore e lokele ditshebediso tse fapaneng, ho tloha phetisong ya matla a tlase ho isa ho a phahameng ho ya ditsamaisong tsa dikoloi.
Tlhahiso ea thepa ea cable ea silane-crosslinked polyethylene (XLPE) e tobane le liphephetso tse kholo tsa tekheniki, ho kenyeletsoa taolo ea pele ho crosslinking, ntlafatso ea ho fokotseha ha mocheso, tokiso ea kristale, le botsitso ba ts'ebetso. Tsoelo-pele ea morao tjena saenseng ea thepa le mekhoa ea tlhahiso e sebetsana le litšitiso tsena, e ntlafatsa boleng ba sehlahisoa haholo le chai ea ts'ebetso.
1. Ho Fokotsa Pele ho Kopanya le ho Chesa
Phephetso:Ts'ebetsong ea Sioplas, ho pepesehela mongobo nakong ea ho kopanya le ho ntša Likarolo tsa A le B ho ka baka karabelo ea hydrolysis le condensation pele ho nako. Sena se lebisa ho hokahanngoa ho sa laoleheng pele ho nako, e leng se fellang ka ho qhibiliha ho hoholo, phallo e fokolang, libaka tse khopameng, le thepa ea ho thibela e senyehileng joalo ka motlakase o tlase oa ho senyeha.
Tharollo:
Kopanyo ea Setlolo se Ekelitsoeng:Ho kenyelletsali-masterbatches tse thehiloeng ho silicone, joalo kaSesebelisoa sa ho lokisa se thehiloeng ho silicone sa SILIKELYPA-208C, e ntlafatsa phallo ea ho qhibiliha ka katleho, e fokotsa ho khomarela ha ho qhibiliha ho li-screw le li-die, 'me e thibela ka katleho ho kopana pele ho li-crosslinking ntle le ho ama boleng ba ho qetela ba ho kopanya li-crosslinking.
Sesebelisoa sa silicone se eketsang LYPA-208Ce na le ts'ebetso e matla ea ho thibela li-crosslinking pele ho li-crosslinking ntle le ho ama boleng ba ho qetela ba li-crosslinking.
Silicone masterbatch LYPA-208C e felisa liphoso tsa bokaholimo tse kang "letlalo la shaka" 'me e ntlafatsa boreledi ba bokaholimo.
Sesebelisoa se eketsang silicone LYPA-208C se fokotsa torque ea extrusion haholo 'me se thibela ho imeloa ha enjene
Litlatsetso tsa Siloxane LYPA-208Ce eketsa botsitso ba mola oa extrusion le sekhahla sa tlhahiso
Ntlafatso ea Gradient ea Mocheso:Ho kenya tshebetsong dithempereichara tsa dibarele tsa extrusion tse arohaneng pakeng tsa 140°C le 180°C ho thusa ho fokotsa ho chesa haholo sebakeng seo. Ho fokotsa nako ya ho dula dibakeng tse nang le mocheso o phahameng ho fokotsa kotsi ya ho hokahana pele ho nako.
Tsamaiso ea Mehato e 'Meli:Ho sebelisa mokhoa oa mehato e 'meli, moo silane e kenngoang holim'a polyethylene pele e ntšoa, ho fokotsa likhatello tse amanang le ho ntšoa ha li-in-line, ka hona ho fokotsa monyetla oa ho hokahana pele ho nako nakong ea ho ntšoa ha li bapisoa le mekhoa ea mohato o le mong.
2. Ntlafatso ea Ts'ebetso ea ho Fokotsa Thermal
Phephetso:Ho fokotseha ho feteletseng ha lera la insulation ho beha kotsing ya ho fetoha ha sebopeho le ho hloleha ha motlakase, ho amanang le tataiso ya kristale le matla a ho phodisa.
Litharollo:
Mekhoa ea ho Pholisa ea Mehato e Mengata:Ho sebelisa tatellano ea mekhahlelo ea ho pholisa ea metsi a chesang, a futhumetseng le a batang ho liehisa sekhahla sa kristale, ho laola ka katleho li-gradient tsa mocheso le ho fokotsa ho fokotseha.
Phetoho ea Paramethara ea Extrusion: Ho sebedisa di-extruder tse nang le karolelano e telele ho isa ho bophara (≥30:1) ho eketsa nako ya ho boloka ho qhibiliha, ho thibela ho kristaleha ho sa batleheng. Ho sebedisa kgatello ho tjhesa dithapo tse nyane (≤6mm²) ho fokotsa ho kristaleha ho bakwang ke ho shebana, ho laola ho nyenyefala ho eketsehileng.
Khetho ea Lisebelisoa:Ho amohela polyethylene e hokahaneng le silane e nang le mehato e 'meli ho lumella taolo e ntle holim'a boitšoaro ba ho etsa kristale, e leng se tlatsetsang ntlafatsong ea botsitso ba mocheso.
3. Ho Leka-lekanya Boleng ba kristale le Thepa ea Mekaniki
Phephetso:Ho ba le kristale e phahameng ho baka ho robeha ha bonolo, athe ho se khanye ha kristale ho sa lekaneng ho fokotsa ho hanyetsa mocheso.
Litharollo:
Taolo ea Mocheso o Qhibilihang:Ho phahamisa mocheso oa ho qhibiliha ho fihlela ho 190°C–210°C ka nako e telele ea ho lula ho fokotsa ho thehoa ha kristale, leha ho le joalo tsamaiso e hlokolosi ea hlokahala ho thibela ho kopana pele ho nako.
Moralo oa Masterbatch oa Catalyst:Ho sebedisa extrusion ya dikurufu tse pedi ho netefatsa ho hasana ho tshwanang ha di-catalyst tsa organotin, ho ntlafatsa tshebedisano pakeng tsa ho kopanya le kristale ho ntlafatsa thepa ya mechini.
4. Ho Ntlafatsa Botsitso ba Ts'ebetso
Phephetso:Ho ba le kutloelo-bohloko ho feto-fetoha ha ts'ebetso ho baka ho se tsitse ha khatello ea extrusion le liphoso tsa bokaholimo.
Litharollo:
Ntlafatso ea Lisebelisoa:Ho kenya tshebetsong ditsamaiso tsa ho kopanya meropa ya dikhoune tse pedi ho netefatsa ho hasana ho hong ha di-additives tsa silane, ka nako ya ho kopanya e fetang dihora tse 2.5 ho fihlella botsitso bo botle.
Tlhokomelo ea Nako ea Sebele:Ho beha leihlo ka ho tsoelang pele ha motlakase oa sekurufu le lebelo la ho potoloha ho lumella liphetoho tse potlakileng ho litlhophiso tsa mocheso le mekhoa ea ho hloekisa hlobo, ho boloka maemo a ts'ebetso a tsitsitseng.
Mekhoa ea Indasteri le Pono ea Bokamoso ea tlhahiso ea likheibole tsa XLPE
Ho kopanngoa ha ts'ebetso ea mehato e 'meli ho kopantsoe le lisebelisoa tse sebetsang, tse kang li-masterbatches tse thehiloeng ho silicone, ho hlahile e le leano le etellang pele la ho hlola liphephetso tsa ts'ebetso tlhahisong ea lithapo tsa XLPE. Ho tlalehoa hore lintho tsena tse ncha li ekelitse chai ea tlhahiso ka ho feta 10 ~ 20% lits'ebetsong tsa liteko, ho ntlafatsa ts'epo ea lithapo tsa XLPE makaleng a phetisetso ea motlakase le likoloi. Ha re sheba pele, bahlahisi ba shebane le lipatlisiso le nts'etsopele ea mahlale a ho pholisa a feto-fetohang le taolo e bohlale ea ts'ebetso ho ntlafatsa ts'ebetso ea thepa ea XLPE haholoanyane, ho fihlela tlhoko e ntseng e hola ea lithapo tse sebetsang hantle.
Ka ho amohela maano ana a tsoetseng pele a ts'ebetso le boqapi ba thepa, bahlahisi ba ka ntlafatsa haholo bokgoni le boleng ba tlhahiso ya dikheibole tsa XLPE, ba netefatsa hore ho tla ba le dihlahiswa tse ntle tse fihlelang ditlhoko tse ntseng di fetoha tsa ditshebediso tsa motlakase tsa sejwalejwale.
