Ingabe ubhekene ne-Torque Ephakeme, i-Die Drool, noma Ukugeleza Okubi kuma-LSZH Cable Compounds?
Izinto zekhebula ze-Low Smoke Halogen-Free (LSZH) ziya ngokuya zibaluleke kakhulu ekuphepheni nasekusimameni kwekhebula lesimanje. Nokho, ukuzuza ukucutshungulwa okuhle kakhulu kuseyinselele. Ukusetshenziswa kakhulu kwezithako ezivimba amalangabi—njenge-aluminium hydroxide (ATH) ne-magnesium hydroxide (MDH)—ngokuvamile kubangela ukugeleza okungekuhle, i-torque ephezulu, ukuqedwa kwendawo emangelengele, kanye nokwakheka kokufa ngesikhathi sokukhipha.
Kungani i-LSZH Cable Compounds kunzima ukuyicubungula?
Izici zentambo nekhebuli ebanga umusi we-halogen engenantuthu ephansi ukuthi zonke izinto azinayo i-halogen, futhi inani elincane kakhulu lentuthu lizokhishwa ngesikhathi sokusha. Ukuze kuzuzwe lezi zici ezimbili ezibalulekile, inani elikhulu lama-flame retardants lanezelwa ohlelweni lokukhiqiza, okuholela ngokuqondile ochungechungeni lwezinkinga zokucubungula.
Okulandelayo amaphuzu ajwayelekile okucubungula amakhebula ekhebula le-halogen engenayo intuthu ephansi:
1. Ngenxa yenani elikhulu lamafila abushelelezi amalangabi afana ne-aluminium hydroxide ne-magnesium hydroxide eyengeziwe, okuholela ekukhoneni okuhle kokugeleza, kanye nokukhiqizwa kokushisa kwe-friction ngesikhathi sokucubungula kuholela ekukhuphukeni kwezinga lokushisa, okuholela ekulimazeni kwe-aluminium hydroxide ne-magnesium hydroxide.
2. Ukusebenza kahle kwe-extrusion okuphansi, kanye nesivinini esiphezulu nakakhulu sokukhipha, umthamo we-extrusion uhlala ungashintshiwe.
3. Ngenxa yokungahambelani kahle kwe-polyolefin nama-flame retardants namanye ama-fillers, okuholela ekuhlakazweni okubi ngesikhathi sokucubungula nokunciphisa izakhiwo zemishini.
4. Ukuhlakazeka okungalingani kwezinqamuleli zamalangabi ezingaphili ohlelweni kuholela endaweni embi kanye nokuntuleka kokucwebezela ngesikhathi sokukhishwa.
5. I-polarity yesakhiwo ye-flame retardant nezinye izigcwalisi zibangela ukuncibilika ukuthi kubambelele ekhanda le-die, kubambezeleke ukudilizwa kwezinto, noma ukuna kwemvula yama-molecule aphansi ekwakhekeni, okuholela ekuqongeleleni kwempahla emlonyeni wokufa, ngaleyo ndlela kuthinte ikhwalithi yekhebula.
Ungaxazulula kanjani ikhebula le-LSZH lezi zinkinga zenqubo kanye nekhwalithi yendawo?
Ukuze unqobe lezi zinkinga,ubuchwepheshe be-silicone masterbatchisibe yisixazululo esithembekile ekwakhiweni kwenhlanganisela ye-LSZH, sithuthukisa kokubili ukusebenza kahle kokucubungula nokusebenza kwendawo ngaphandle kokuyekethisa izakhiwo zemishini noma zikagesi.
Kungani kunjaloi-silicone masterbatch isisombululo esisebenzayoukuze kuthuthukiswe ukucutshungulwa nokusebenza kwendawo yekhebula le-LSZH?
I-Silicone masterbatch iwuhlobo lweisithasiselo sokucubungula esisebenzayongama-thermoplastic ahlukahlukene njengabathwali kanye ne-polysiloxane njengezingxenye zokusebenza. Ngakolunye uhlangothi, i-silicone based masterbatch ingathuthukisa ikhono lokugeleza kwesistimu ye-thermoplastic ngesikhathi sokuncibilika, ithuthukise ukuhlakazwa kwama-fillers, inciphise ukusetshenziswa kwamandla kwe-extrusion nokubunjwa komjovo, futhi ithuthukise ukusebenza kahle kokukhiqiza; Ngakolunye uhlangothi, lolu sizo lokucubungula olususelwa ku-Silicone lungabuye luthuthukise ukushelela kwemikhiqizo yepulasitiki yokugcina, lunciphise i-coefficient yokungqubuzana kwendawo futhi luthuthukise ukumelana nokuguga nokuklwebheka. Ngaphezu kwalokho, njengosizo lokucubungula embonini ye-thermoplastic, i-silicone masterbatch ingakwazi ukufeza umphumela ocacile wokuguqulwa ngenani elincane (< 5%), ngaphandle kokucatshangelwa okuningi kokusabela kwayo ngezinto ze-matrix.
I-Chengdu Silike Technology Co., Ltd. ingumkhiqizi ohamba phambili waseShayina onguchwephesheizithasiselo ezisekelwe ku-siliconeizimboni zepulasitiki nezenjoloba. Eminyakeni engaphezu kwengu-20 yocwaningo oluzinikele olugxile ekuhlanganisweni kwe-silicone nama-polymers, i-Silike isizisungule njengozakwethu osanda kuhlanganyela nomethembayo wezisombululo zezengezo ezisebenza kahle kakhulu.
Ukusiza abakhiqizi ekuzulazuleni izinselele zokukhiqiza ezihlobene nezintambo ze-LSZH, i-Silike ithuthukise iphothifoliyo epheleleizithasiselo zepulasitiki ze-siliconeyakhelwe ngokukhethekile ukuthuthukisa ukucutshungulwa kwezinhlanganisela zekhebula. Imikhiqizo ephawulekayo, efana ne-Silicone Masterbatch LYSI-401 kanye ne-Silicone Masterbatch LYSI-502C, inikeza izixazululo eziphumelelayo ezihloselwe ukuthuthukisa ukucutshungulwa kanye nekhwalithi yobuso, ngaleyo ndlela ibe nomthelela ekusebenzeni okuphakeme ekufakweni kwezintambo nezintambo.
Izinzuzo Zokusebenza: Imiphumela Yokuhlola Ejwayelekile Ye-Silicone Masterbatch kuma-LSZH Cable Compounds
Kwengeza u-SILIKEI-Silicone Masterbatch ( Siloxane Masterbatch ) uchungechunge lwe-LYSIohlelweni lokugcwalisa oluncisha ilangabi eliphezulu lezinto zekhebula ezingenawo intuthu ye-halogen lungathuthukisa uketshezi lokucubungula, lunciphise i-torque, futhi luthuthukise ukusebenza kahle kokukhiqiza. Umfanekiso 1 ubonisa ukuqhathaniswa kokuhlolwa kokusebenza kwekhebula ngemva kokwengeza u-1%I-LYSI-401 silicone masterbatchkufomula yenkampani yethu elingisiwe evamile engenantuthu ye-halogen (Ithebula 1). Kuyabonakala ukuthi ukusebenza okufanelekile kuye kwathuthukiswa kakhulu.
Fig.2 , Fig.3, and Figure 4 show the torque rheometer test of siloxane High ContentI-Silicone masterbatch LYSI-502Cyengezwe kufomula evamile ephansi ye-halogen engenayo intuthu kanye nokuqhathaniswa netorque, ingcindezi, kanye ne-shear viscosity yemikhiqizo yokuncintisana yangaphandle. Kuyabonakala ukuthi i-LYSI-502C inokusebenza okuhle kakhulu kokugcoba.
Umfanekiso wesi-5 unikeza ukulingisa okubalulekile kokunqwabelana kwezinto ngaphakathi kwentambo yokufa ye-extrusion ngemva kokwengezwa kwe-silicone masterbatch. Imiphumela yembula ukuthi ukufakwa kwe-silicone masterbatch ejwayelekile kunciphisa kakhulu i-die buildup. Ngaphezu kwalokho, i-SILIKE'shigh molecular weight abicah masterbatchikhombisa umphumela ogqame nakakhulu ekunciphiseni ukwakheka kokufa, okubonisa amandla ayo okuthuthukisa ukusebenza kahle kokucubungula.
Isifinyezo:I-siloxane ekhona ngokwezingaama-silicone masterbatchesi-nonpolar, engadala izinselele uma kubhekwa imingcele ehlukene yokuncibilika kwamapholymer amaningi we-carbon chain. Uma ukungezwa kudlulele, kungase kuhilele ezinkingeni ezifana nokushelela kwesikulufu, ukuthambisa ngokweqile, ukuncipha kwendawo yomkhiqizo, ukusebenza kwebhondi esengozini, kanye nokuhlakazeka okungalingani ngaphakathi kwe-substrate.
Ukubhekana nalezi zinselelo, i-SILIKE yenze uchungechunge lweIzithasiselo ze-silicone ezinesisindo esikhulu samangqamuzanaeziguqulwa ngamaqembu asebenzayo akhethekile. Leziizithasiselo ze-silicone-based polymer processingaklanyelwe ukuhlangabezana nezidingo ezithile zohlelo lokusebenza kuwo wonke amasistimu we-thermoplastic ahlukahlukene. Ngokusebenza njengamahange ngaphakathi kwe-substrate, bathuthukisa ukuhambisana, bathuthukise ukuhlakazeka, futhi baqinise ukunamathela. Lokhu kuphumela ekusebenzeni okuthuthuke kakhulu kukonke kwe-substrate. Kumasistimu angenantuthu ephansi, angenayo i-halogen, lezi zengezo ezintsha zivimbela ngempumelelo ukushelela kwesikulufu futhi zinciphisa ngokuphawulekayo ukunqwabelana kwezinto ezifayo.
Ingabe ufuna ii-polymer processing additiveukuthuthukisa inqubo yakho yokukhiqiza ikhebula le-LSZH?
Hlola ukuthi izisombululo ze-silicone ezisekelwe ku-masterbatch ze-SILIKE, okuhlanganisa isithako se-silicone i-LYSI-401 kanye ne-siloxane masterbatch LYSI-502C, ezingakusiza kanjani ekuthuthukiseni ukukhiqiza, ekwehliseni ukulungiswa kokufa, nasekufinyeleleni ikhwalithi yekhebula ephezulu. Sikumema ukuthi usithinte ukuze uthole imininingwane eyengeziwe futhi ucele isampula.
