Indlela yokuthuthukisa ukuhlakazeka kwama-flame retardants

Ngokusetshenziswa okubanzi kwezinto ze-polymer kanye nemikhiqizo yabathengi be-elekthronikhi ekuphileni kwansuku zonke, izigameko zomlilo nazo ziyanda, futhi umonakalo owulethayo usabisa nakakhulu. Ukusebenza kwe-flame retardant yezinto ze-polymer sekubaluleke nakakhulu, ukuze kuzuzwe izidingo ze-flame retardant yamapulasitiki nemikhiqizo yenjoloba, ukunciphisa ukungcoliswa kothuli okubangelwa ama-flame retardants, i-masterbatch ye-flame retardant yaba khona, futhi idlala indima ebalulekile. kanye nendima ebalulekile ekubunjweni kwemikhiqizo yokugcina.

I-masterbatch ye-flame retardant yenziwa ngokwefomula enengqondo, ngenhlanganisela yezinto eziphilayo ze-flame retardant, i-lubricant dispersant kanye ne-carrier, ngokucwengisiswa okuminyene, ukuxuba, ukufana kanye ne-extrusion granulation. Kulokhu, i-dispersant idlala indima ebaluleke kakhulu, engeza ingxenye ethile ye-dispersant ingaba kuhle kakhulu ukukhuthaza ukuhlakazeka kwe-flame retardant, ukuze kube lula ukuhlakazeka ngokulinganayo kule nqubo, ukuvimbela ukuhlangana kwe-flame retardant, ngcono umphumela wokuhlakaza, ukuze wenze ama-molecule abushelelezi amalangabi adlale umphumela ongcono wokunqanda ilangabi, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwe-flame retardant yepulasitiki, imikhiqizo yenjoloba, umlilo uzobe uklinywa ekuqaleni.

Kodwa-ke, ekusebenzeni, amapulasitiki amaningi kanye nezingxenye zenjoloba eziqukethe izingxenye ze-flame-retardant azikwazi ukwenza izakhiwo zazo ezivimbela amalangabi ngenxa yokuhlakazeka okungalingani kwe-flame-retardant ezintweni emlilweni, okuholela emlilweni omkhulu kanye nokulahlekelwa okukhulu.

Ukuze kuthuthukiswe ukuhlakazwa komfaniswano kwama-flame retardants noma i-flame retardant masterbatch enqubweni yokubumba umkhiqizo, ukunciphisa ukwenzeka kokuhlakazeka okungalingani okubangelwa umphumela we-flame retardant akukwazi ukukhishwa ngokuphumelelayo, njll., futhi kuthuthukise ikhwalithi yemikhiqizo ye-flame retardant, I-SILIKE yenze isengezo esilungisiwe se-silicone SILIMER hyperdispersant.

I-SILIMER iwuhlobo lwe-tri-block copolymerized modified siloxane eyakhiwa ama-polysiloxanes, amaqembu amhlophe namaqembu amaketango amade ekhabhoni. Izingxenye zeketanga le-polysiloxane zingadlala indima ethile yokuhlukanisa phakathi kwama-molecule abushelelezi ilangabi ngaphansi kwe-shear mechanical, ukuvimbela i-agglomeration yesibili yama-molecule e-retardant flame; izingxenye ze-polar chain chain zinesibopho esithile ne-flame retardant, edlala indima yokuhlanganisa; izingxenye ezinde ze-carbon chain zinokuhambisana okuhle kakhulu nezinto eziyisisekelo.

Lolu chungechunge lwemikhiqizo lufanele ama-thermoplastic resins avamile, i-TPE, i-TPU namanye ama-elastomers ashisayo, futhi ingathuthukisa ukuhambisana phakathi kwama-pigments/filler powders/functional powders kanye nezinhlelo ze-resin, futhi igcine isimo sokuhlakazeka kwezimpushana sizinzile.

Ngasikhathi sinye, inganciphisa i-viscosity yokuncibilika, inciphise i-torque ye-extruder, ingcindezi ye-extrusion, ithuthukise ukusebenza kokusebenza kwento, ngokugcotshwa okuhle kokucutshungulwa, futhi ngasikhathi sinye ithuthukise umuzwa we-extruder. ubuso bezinto, ngezinga elithile lobushelelezi futhi akuthinti izakhiwo zemishini yezinto ezibonakalayo, ukukhuthaza ukuhlakazeka okufanayo kwezingxenye ezinqanda ilangabi ukuze kuthuthukiswe umphumela we-flame retardant womkhiqizo wokugcina ukunikeza ukudlala okugcwele phezulu. -izixazululo zekhwalithi.

Ngaphezu kwalokho, lolu chungechunge lwemikhiqizo alufanele kuphela i-masterbatch ye-flame retardant, kodwa futhi i-masterbatch yombala noma izinto ezihlakazekile eziphezulu ezihlakazekile.
