Ungazixazulula kanjani izinkinga zokucubungula izinto zekhebula ezingenayo intuthu encane ye-halogen?

I-LSZH imele ama-halogen angenamusi ophansi, angenamusi ophansi, lolu hlobo lwekhebula nentambo lukhipha intuthu encane kakhulu futhi alukhiphi ama-halogen anobuthi uma luvezwa ekushiseni. Kodwa-ke, ukuze kufezwe lezi zinto ezimbili ezibalulekile, ekukhiqizweni kwezinto zekhebula ezingenamusi ophansi, ama-halogen angenamusi ophansi (LSZH) alayishwa kakhulu, okuholela ngqo ezimpahleni zomshini nezokucubungula.

Ubunzima ekucutshungulweni kwezinto ezingenayo i-halogen eningi:

1. Ifomula evamile, ama-compound ekhebula le-LSZH polyolefin agcwele okuqukethwe okuphezulu aqukethe kufika ku-55-70% ATH/MDH, Njengoba inani elikhulu le-aluminium hydroxide, i-magnesium hydroxide, nezinye izinto ezivimbela ilangabi ukuze zijoyine ukusetshenziswa kokunyakaza kwesistimu zimbi, ukukhiqizwa kokushisa okungqubuzanayo ngesikhathi sokucubungula kuholela ekwandeni kwezinga lokushisa okubangela ukuwohloka kwe-aluminium kanye ne-magnesium hydroxide.

2. Ukusebenza kahle kwe-extrusion okuphansi, noma ngabe ukhulisa ijubane levolumu ye-extrusion kuhlala kufana.

3. Ukuhambisana okungekuhle kwezithiyo zomlilo ezingaphili kanye nezigcwalisi nama-polyolefin, ukuhlakazeka okungekuhle ngesikhathi sokucubungula, okuholela ekunciphiseni kwezakhiwo zemishini.

4. Ubuso obuqinile kanye nokuntuleka kokukhanya ngesikhathi sokukhipha ngenxa yokusabalala okungalingani kwezinto ezivimbela ilangabi ezingaphili ohlelweni.

5.Ukwakheka kwe-polarity yezinto ezivimbela ilangabi kanye nezigcwalisi kubangela ukuthi ukuncibilika kunamathele ekhanda lesikhunta, okubambezela ukukhishwa kwezinto ezivela kusikhunta, noma ama-molecule amancane aqunyiwe aphume, okuholela ekuqongeleleni kwezinto lapho kuvuleka khona isikhunta, ngaleyo ndlela kuthinte ikhwalithi yekhebula.

Ngokusekelwe ezindabeni ezingenhla, i-SILIKE isungule uchungechunge lwezinhleloisithasiselo se-siliconeimikhiqizo eyenzelwe ngqo ukubhekana nezinkinga zokucubungula kanye nekhwalithi ephezulu yezinto zekhebula ezingenayo intuthu encane ye-halogen, ama-wire & cable compounds angenawo intuthu encane ye-halogen, noma amanye ama-Polyolefin agcwele amaminerali amaningi okusetshenziswa kwezintambo nezintambo, enikeza izixazululo ezahlukahlukene ezisebenzayo kulezi zinselele.

Isib:I-Silicone Masterbatch (i-Siloxane Masterbatch) i-LYSI-401iyifomula eyenziwe nge-pelletized ene-polymer ye-siloxane ye-molecular weight ephezulu engu-50% ehlakazeke kwi-polyethylene ephansi (i-LDPE). Isetshenziswa kabanzi njengesithasiselo sokucubungula esisebenzayo ezinhlelweni ze-resin ezihambisana ne-PE ukuthuthukisa izakhiwo zokucubungula nokushintsha ikhwalithi yobuso.

Ukwengeza u-0.5-2% weI-SILIKE silicone masterbatch LYSI-401Uhlelo lokugcwalisa olusebenzisa amalangabi amaningi olusebenzisa ama-halogen angenawo umusi noma ama-halogen angenawo umusi angenawo umoya (LSZH) luvumela abenzi bezintambo namakhebula ukuthi bandise umkhiqizo, bangathuthukisa ukugeleza kokucubungula, banciphise i-torque, basheshise isivinini somugqa wokukhipha umphezulu ngaphandle kokufuduka, bathuthukise ikhwalithi yomphezulu wentambo nekhebula, (I-coefficient ephansi yokungqubuzana, Ukumelana nokuklwebheka okuthuthukisiwe nokuguguleka, ukushelela okungcono komphezulu, kanye nokuzwa kwesandla ...) ngaphandle kokukhokha iprimiyamu yezithasiselo zokusebenza ezingadingeki.

Ngokuvamile, ngokwejwayelekilei-silicone masterbatch, i-siloxane ayiyona i-polar, futhi iningi lamapharamitha okuncibilika kwe-carbon chain polymer omehluko makhulu kakhulu, ukwengezwa kwenani elikhulu lamacala kungaholela ekucutshungulweni kokushelela kwesikulufo, ukugcotshwa ngokweqile, ubuso bokwehlukaniswa komkhiqizo, okuthinta ubuso bemikhiqizo yezakhiwo zokubopha zemikhiqizo engaphansi komhlaba ezihlakazekile ngokungalingani njalo njalo.

Ngesikhathi,Izithasiselo ze-silicone ze-SILIKE ezinesisindo sama-molecule esiphezulu kakhuluziguqulwa ngamaqembu akhethekile, angakhethwa futhi afaniswe ngokwezidingo ezahlukene zezithasiselo ze-silicone kuma-substrate ahlukene. Lolu chungechunge lwemikhiqizo lungadlala indima yokubambelela ku-substrate, ngaleyo ndlela luhambisane kangcono ne-substrate, luhlakazeke kalula, lubopheke ngokuqinile, futhi ngaleyo ndlela lunikeze i-substrate ukusebenza okuhle kakhulu. Uma isetshenziswa ezinhlelweni ze-LZSH kanye ne-HFFR, ingagwema ngempumelelo ukushelela kwezikulufo futhi ingadlala indima ebalulekile ekuthuthukiseni ukuqongelela kwezinto ezikubunjeni bomlomo.
