Silicone masterbatchni ubwoko bwinyongera mubikorwa bya reberi na plastike. Ikoranabuhanga ryateye imbere mubijyanye ninyongeramusaruro ya silicone nugukoresha uburemere bukabije bwa molekile (UHMW) silicone polymer (PDMS) mumashanyarazi atandukanye, nka LDPE, EVA, TPEE, HDPE, ABS, PP, PA6, PET, TPU , HIPS, POM, LLDPE, PC, SAN, nibindi kandi nka pellet kugirango yemere kongerwaho byoroshye inyongeramusaruro kuri thermoplastique mugihe cyo gutunganya. guhuza gutunganya neza hamwe nigiciro cyoroshye. Igishushanyo mbonera cya silicone kiroroshye kugaburira, cyangwa kuvanga, muri plastiki mugihe cyo guteranya, gukuramo, cyangwa gutera inshinge. Nibyiza kuruta amavuta yumushashara hamwe nibindi byongeweho mugutezimbere kunyerera mugihe cyo gukora. Rero, abatunganya plastike bahitamo kubikoresha mubisohoka.

Uruhare rwaSilicone Masterbatch yongeyehomugutezimbere gutunganya plastike

Igishushanyo mbonera cya silicone nimwe mumahitamo azwi cyane kubatunganya mugutunganya plastike no kuzamura ubuziranenge bwubutaka. Nubwoko bwa super lubricant. Ifite imirimo yingenzi ikurikira iyo ikoreshejwe muri resimoplastique:

A. Kunoza imigendekere ya resin no kuyitunganya;

Ibyiza byo kuzuza no kubumba ibintu

Kugabanya torque ya extrude no kunoza igipimo cyo gukuramo;

B. Itezimbere imiterere yubuso

Kunoza ubuso bwa plastike kurangiza, kurwego rworoshye, no kugabanya coefficient de coiffure yuruhu, Kunoza imyambarire no kwihanganira;

Kandi silicone masterbatch ifite ubushyuhe bwiza bwumuriro (ubushyuhe bwumuriro ni 430 ℃ muri azote) no kutimuka;

Kurengera ibidukikije;

Guhuza umutekano n'ibiryo.

Tugomba kwerekana ko ibikorwa byose bya silicone masterbatches ari ibya A na B (ingingo ebyiri zavuzwe haruguru twavuze) ariko ntabwo ari ingingo ebyiri zigenga ariko

kuzuzanya, kandi bifitanye isano ya hafi.

Ingaruka kubicuruzwa byanyuma

Bitewe nibiranga imiterere ya molekile ya siloxane, dosiye ni nto cyane kuburyo muri rusange hafi ya yose nta ngaruka zigira kumitungo yubukorikori bwibicuruzwa byanyuma. muri rusange tuvuze, usibye kuramba n'imbaraga biziyongera gato, nta ngaruka kubindi bikoresho bya mashini. Kuri dosiye nini, ifite imbaraga zo guhuza hamwe na flame retardant agent.

Bitewe nibikorwa byindashyikirwa kurwego rwo hejuru nubushyuhe buke, ntabwo bizagira ingaruka mbi kurwego rwo hejuru nubushyuhe buke bwibicuruzwa byanyuma. mugihe urujya n'uruza rwa resin, gutunganya, nubuso bwubutaka bizanozwa neza kandi COF izagabanuka.

Uburyo bwibikorwa

Siliconeni ultra-high molekulari yuburemere polysiloxane ikwirakwijwe mubisumizi bitandukanye byubwoko nuburyo bwimikorere masterbatch. Iyo uburemere burenze urugerosilicone masterbatchesbyongewemo muri plastiki kubintu bidafite inkingi kandi bifite ingufu nkeya, bifite icyerekezo cyo kwimukira hejuru ya plastike mugihe cyo gushonga; mugihe, kubera ko ifite uburemere bunini bwa molekile, ntishobora kwimuka burundu. Tuyita rero ubwumvikane nubumwe hagati yimuka no kutimuka. bitewe niyi mitungo, amavuta yo kwisiga afite imbaraga hagati yubuso bwa plastike na screw.

Hamwe no gutunganya komeza, iyi mavuta yo kwisiga ihora ikurwaho kandi ikabyara umusaruro. Gutembera rero kwa resin no gutunganya bigenda bitera imbere buri gihe kandi bigabanya amashanyarazi, ibikoresho byumuriro no kuzamura umusaruro. Nyuma yo gutunganya twin-screw, silicone masterbatches izagabanywa neza muri plastiki hanyuma ikore igice cya peteroli ya 1 kugeza kuri 2 munsi ya microscope, ibyo bice byamavuta bizatanga ibicuruzwa neza, kumva neza amaboko, COF yo hepfo, nibindi byinshi abrasion hamwe no guhangana.

Duhereye ku ishusho dushobora kubona ko silicone izahinduka uduce duto nyuma yo gutatanyirizwa muri plastiki, ikintu kimwe tugomba kwerekana ni uko gutatanya aricyo kintu cyingenzi cyerekana ibihangano bya silicone, bito bito, bikagabanywa cyane, ibisubizo byiza tuzabona.
