Top Class Material Vacuum Casting TPU

Top Grade Material Vacuum Casting TPU Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Hei-Cast 8400 ndi 8400N ndi zigawo zitatu za polyurethane elastomers zomwe zimagwiritsidwa ntchito popanga vacuum zomwe zimakhala ndi izi:

(1) Pogwiritsa ntchito "gawo la C" pakupanga, kuuma kulikonse mumtundu wa A10 ~ 90 kungapezeke / kusankhidwa.
(2) Hei-Cast 8400 ndi 8400N ndi otsika mamasukidwe akayendedwe ndi kusonyeza bwino otaya katundu.
(3) Hei-Cast 8400 ndi 8400N amachiritsa bwino kwambiri ndikuwonetsa kukhazikika kwabwino kwambiri.

8. Njira Yopangira Vuto

(1) Kulemera
Sankhani kuchuluka kwa "C chigawo" molingana ndi kuuma komwe mukufuna ndikuwonjezera ku gawo A.
Yezerani kuchuluka komweko potengera kulemera kwa chigawo B monga gawo la A mu kapu yosiyana poganizira kuchuluka komwe kungatsale mu kapu.

(2) Kuchotsa mpweya
Chitani pre-degassing mu chipinda chochotsera mpweya kwa mphindi 5.
Degass momwe mungafunire.
Tikukulimbikitsani kuti muchotse gasi mukatenthetsa zinthu mpaka kutentha kwamadzimadzi kwa 25 ~ 35 ° C.

(3) Kutentha kwa utomoni
Pitirizani kutenthare of25-35 °C za onse A(muli C gawo) ndi B gawo.
Kutentha kwa zinthu kukakwera, moyo wa mphika wosakaniza udzakhala waufupi ndipo kutentha kwa zinthu kukatsika, moyo wa mphika wosakaniza udzakhala wautali.

(4) Kutentha kwa nkhungu
Sungani kutentha kwa nkhungu ya silikoni isanayambe kutentha mpaka 60 ~ 700C.
Kutentha kwambiri kwa nkhungu kungayambitse kuchiritsa kosayenera kumabweretsa kuchepa kwa thupi.Kutentha kwa nkhungu kuyenera kuyang'aniridwa bwino momwe kungakhudzire kulondola kwa nkhaniyo.

(5) Kuponya
Zotengera zimayikidwa m'njira yotiB gawo is anawonjezera to A gawo (kokusamala C gawo).
Ikani vacuum mu chipinda ndikuchotsa mpweya A chigawo chimodzi kwa mphindi 5-10pamene it is kugwedezeka nthawi ndi nthawi.
Onjezani B gawo to A gawo(muli C gawo)ndikuyambitsanso kwa 30 ~ 40 masekondi ndikuponya kusakaniza mwachangu mu nkhungu ya silicone.
Tulutsani vacuum mu mphindi imodzi ndi theka mutayamba kusakaniza.

(6) Kuchiritsa mkhalidwe
Ikani nkhungu yodzaza mu uvuni wa thermostatic wa 60 ~ 700C kwa mphindi 60 pamtundu wa A hardness 90 ndi kwa mphindi 120 pamtundu wa A kuuma 20 ndikuwongoleredwa.
Chitani pochiritsa pa 600C kwa 2 ~ 3 maola kutengera zofunikira.

9. Tchati choyenda cha vacuum casting

10. Kusamala posamalira

(1) Monga mbali zonse za A, B ndi C zimakhudzidwa ndi madzi, musalole kuti madzi alowe muzinthuzo.Pewaninso zinthu zomwe zingakhudze chinyezi kwa nthawi yayitali.Tsekani chidebe cholimba mukatha kugwiritsa ntchito.

(2) Kulowa kwa madzi mu gawo la A kapena C kungayambitse kutulutsa thovu la mpweya wambiri mu mankhwala ochiritsidwa ndipo ngati izi zingachitike, timalimbikitsa kutentha gawo la A kapena C mpaka 80 ° C ndi kupukuta pansi pa vacuum kwa mphindi 10.

(3) Kagawo kakang'ono kadzaundana pa kutentha kosachepera 15°C.Kutenthetsa mpaka 40 ~ 50 ° C ndikugwiritsa ntchito mutagwedeza bwino.

(4) B chigawocho chimachita ndi chinyezi kuti chisanduke chipwirikiti kapena kuchiritsa kukhala zinthu zolimba.Osagwiritsa ntchito zinthuzo zitataya kuwonekera kapena zawonetsa kuuma kulikonse chifukwa zida izi zitha kupangitsa kuti zinthu zikhale zotsika kwambiri.

(5) Kutentha kwa nthawi yaitali kwa gawo la B pa kutentha kwa 50 ° C kudzakhudza ubwino wa chigawo cha B ndipo zitini zimatha kutenthedwa ndi kuwonjezereka kwa mkati.Sungani kutentha.

11. Kusamala pa Chitetezo ndi Ukhondo

(1) B chigawo chili ndi zoposa 1% ya 4,4'-Diphenylmethane diisocyanate.Ikani utsi wa m'deralo mkati mwa malo ogwirira ntchito kuti muteteze mpweya wabwino wa mpweya.

(2) Samalani kuti manja kapena khungu lisakhudzidwe ndi zipangizo.Mukakhudzana, yambani ndi sopo ndi madzi nthawi yomweyo.Zitha kukwiyitsa manja kapena khungu ngati zisiyidwa kukhudzana ndi zopangira kwa nthawi yayitali.

(3) Zinthu zikalowa m'maso, tsukani ndi madzi oyenda kwa mphindi 15 ndikuyitana dokotala.

(4) Ikani njira ya pampu ya vacuum kuti muwonetsetse kuti mpweya watha kunja kwa malo ogwirira ntchito.
