Ma polymer matrix composites opangidwa ndi ulusi wagalasi ndi zinthu zofunika kwambiri pakupanga, ndi omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi, makamaka chifukwa chosunga kulemera kwawo pamodzi ndi kuuma kwawo komanso mphamvu zawo.

Polyamide 6 (PA6) yokhala ndi 30% Glass Fibre (GF) ndi imodzi mwa ma polima omwe amagwiritsidwa ntchito kwambiri chifukwa cha ubwino wake monga ubwino, makhalidwe abwino a makina, kutentha kwambiri, mphamvu yovunda, kubwezeretsanso, ndi zina. Amapereka zipangizo zabwino kwambiri zogwiritsira ntchito zipolopolo za zida zamagetsi, zida zamagetsi, zida zamakina aukadaulo, ndi zida zamagalimoto.

Komabe, zipangizozi zilinso ndi zovuta, monga njira zopangira nthawi zambiri zimakhala kupanga jakisoni. Kuthamanga kwa nayiloni yolimbikitsidwa ndi ulusi ndi kochepa, zomwe zimapangitsa kuti jakisoni ikhale yothamanga kwambiri, kutentha kwambiri kwa jakisoni, jakisoni wosakwanira, ndi mabala oyera a radial omwe amawonekera pamwamba. Chodabwitsachi chimadziwika kuti "ulusi woyandama", chomwe sichivomerezeka pazigawo zapulasitiki zomwe zimafunikira mawonekedwe apamwamba pakuumba jakisoni.

Ngakhale, popanga zinthu zopangidwa ndi jakisoni, mafuta odzola sangawonjezedwe mwachindunji kuti athetse vutoli, ndipo nthawi zambiri, ndikofunikira kuwonjezera mafuta mu fomula yosinthidwa pa zopangira kuti zitsimikizire kuti chowonjezera cha ulusi wagalasi chalowetsedwa bwino.

Chowonjezera cha silikoniimagwiritsidwa ntchito ngati chothandizira kwambiri pakupanga ndi mafuta. Chosakaniza chake cha silicone chimapangitsa kuti kufalikira kwa filler kukhale bwino mu mawonekedwe odzazidwa komanso momwe polymer melt imayendera. Izi zimawonjezera mphamvu yotulutsa zinthu. Zimachepetsanso mphamvu yofunikira pakupanga zinthu, Nthawi zambiri, mlingo wa silicone adjuvant ndi 1 mpaka 2 peresenti. Chogulitsachi n'chosavuta kudyetsedwa ndi dongosolo lokhazikika ndipo chimaphatikizidwa mosavuta mu zosakaniza za polymer pa chotulutsira zinthu cha twin-screw.

Kugwiritsa ntchitochowonjezera cha silikonimu PA 6 yokhala ndi ulusi wagalasi wa 30% yapezeka kuti ndi yothandiza pa ntchito zosiyanasiyana. Mwa kuchepetsa kuchuluka kwa ulusi womwe umawululidwa pamwamba pa chinthucho, zowonjezera za silicone zingathandize kupanga kumalizidwa kosalala ndikuwonjezera kuyenda. Kuphatikiza apo, zingathandizenso kuchepetsa kupindika ndi kuchepa panthawi yopanga komanso kuchepetsa phokoso ndi kugwedezeka panthawi yogwira ntchito. motero,zowonjezera za silikonindi njira yothandiza kwa opanga omwe akufuna kukonza zinthu zawo.

Kupanga Njira Zochepetsera Kuwonekera kwa Ulusi wa Galasi wa Polyamide 6 PA6 GF30

SILIKE Silicone MasterbatchLYSI-407 imagwiritsidwa ntchito kwambiri ngati chowonjezera chogwira ntchito bwino pamakina a utomoni ogwirizana ndi PA6 kuti ikonze bwino momwe zinthu zimagwirira ntchito komanso momwe zinthu zilili pamwamba pake, monga kuthekera koyenda bwino kwa utomoni, kudzaza ndi kutulutsa nkhungu, mphamvu yochepa yotulutsa utomoni, kutsika kwa coefficient of friction, kukana kwambiri kwa mar ndi abrasion.Chinthu chimodzi chofunikira kuwunikira chimathandiza kuthetsa mavuto okhudzana ndi kuwala kwa ulusi wa galasi mu kupanga jakisoni wa PA6 GF 30.
