Indlela yokuthuthukisa ukusabalala kwezithiyo zomlilo

Ngokusetshenziswa kabanzi kwezinto ze-polymer kanye nemikhiqizo yabathengi be-elekthronikhi empilweni yansuku zonke, ukwanda komlilo nakho kuyakhula, futhi umonakalo okuwulethayo uyethusa nakakhulu. Ukusebenza kwezinto ze-polymer ezivimbela ilangabi sekubaluleke kakhulu, kungenxa yokufeza izidingo ze-flame retardant zepulasitiki nemikhiqizo yerabha, ukunciphisa ukungcola kothuli okubangelwa yi-flame retardant, i-masterbatch evimbela ilangabi yaqala ukuba khona, futhi idlala indima ebalulekile ekubunjweni kwemikhiqizo yokugcina.

I-masterbatch evimbela ilangabi yenziwa ngokwefomula enengqondo, ngokusebenzisa inhlanganisela yezinto eziphilayo ye-flame retardant, i-lubricant dispersant kanye ne-carrier, ngokusebenzisa ukuhluzwa okujulile, ukuxuba, ukufana bese kuba yi-extrusion granulation. Kulokhu, i-dispersant idlala indima ebaluleke kakhulu, engeza ingxenye ethile ye-dispersant ingaba kuhle kakhulu ukukhuthaza ukusabalala kwe-flame retardant, ukuze kube lula ukuhlakazeka ngokulinganayo enkambisweni, ukuvimbela ukuhlangana kwe-flame retardant, lapho umphumela wokuhlakazeka uba ngcono, ukuze ama-molecule e-flame retardant adlale umphumela ongcono we-flame retardant, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwe-flame retardant yepulasitiki, imikhiqizo yerabha, umlilo uzoklinywa esigabeni sokuqala.

Kodwa-ke, empeleni, izingxenye eziningi zepulasitiki nerabha eziqukethe izingxenye ezivimbela umlilo azikwazi ukwenza izakhiwo zazo ezivimbela umlilo ngenxa yokusabalala okungalingani kwezinto ezivimbela umlilo ezintweni ezisemlilweni, okuholela emlilweni omkhulu kanye nokulahlekelwa okukhulu.

Ukuze kukhuthazwe ukusabalala okufanayo kwezithiyo zomlilo noma i-masterbatch evimbela umlilo enqubweni yokubumba umkhiqizo, kuncishiswe ukwenzeka kokusabalala okungalingani okubangelwa umphumela wokuthiyo womlilo awukwazi ukusetshenziswa kahle, njll., futhi kuthuthukiswe ikhwalithi yemikhiqizo evimbela umlilo, i-SILIKE ithuthukise i-SILIMER hyperdispersant eguquliwe ye-silicone.

I-SILIMER uhlobo lwe-siloxane eguquliwe ehlanganisiwe ene-tri-block eyakhiwe ngama-polysiloxanes, amaqembu e-polar kanye namaqembu e-long carbon chain. Izingxenye ze-polysiloxane chain zingadlala indima ethile yokuhlukanisa phakathi kwama-molecule e-flame retardant ngaphansi kwe-mechanical shear, okuvimbela ukuhlangana kwesibili kwama-molecule e-flame retardant; izingxenye ze-polar group chain zinesibopho esithile ne-flame retardant, zidlala indima yokuhlanganisa; izingxenye ze-long carbon chain zinokuhambisana okuhle kakhulu nezinto eziyisisekelo.

Lolu chungechunge lwemikhiqizo lufanelekela ama-resin avamile e-thermoplastic, i-TPE, i-TPU kanye namanye ama-elastomer e-thermoplastic, futhi lungathuthukisa ukuhambisana phakathi kwama-pigment/izimpushana zokugcwalisa/izimpushana ezisebenzayo kanye nezinhlelo ze-resin, futhi lugcine isimo sokusabalala kwezimpushana sizinzile.

Ngesikhathi esifanayo, kunganciphisa futhi i-viscosity yokuncibilika, kunciphise i-torque ye-extruder, ingcindezi ye-extrusion, kuthuthukise ukusebenza kokucubungula kwezinto, ngokugcoba okuhle kokucubungula, futhi ngasikhathi sinye kungathuthukisa ngempumelelo umuzwa wobuso bezinto, ngezinga elithile lokushelela futhi akuthinti izakhiwo zemishini zezinto, ukukhuthaza ukuhlakazeka okufanayo kwezingxenye ezivimbela ilangabi ukukhuthaza umphumela we-flame retardant womkhiqizo wokugcina ukuze kunikezwe ukudlala okugcwele izixazululo zekhwalithi ephezulu.

Ngaphezu kwalokho, lolu chungechunge lwemikhiqizo alufaneleki nje kuphela kwi-masterbatch evimbela ilangabi, kodwa futhi nakwi-masterbatch yombala noma izinto ezihlakazekile kakhulu.
