ABS pulasitiki zinthu

Dzina la mankhwala: Acrylonitrile-butadiene-styrene copolymer
Dzina la Chingerezi: Acrylonitrile Butadiene Styrene
Kukoka kwapadera: 1.05 g/cm3 Kuchepa kwa nkhungu: 0.4-0.7%
Akamaumba kutentha: 200-240 ℃ kuyanika zinthu: 80-90 ℃ 2 hours
Mawonekedwe:
1.Kugwira ntchito bwino, mphamvu zogwira mtima kwambiri, kukhazikika kwa mankhwala, ndi magetsi abwino.
2.Ili ndi weldability wabwino ndi 372 plexiglass ndipo imapangidwa ndi zigawo ziwiri zapulasitiki zamitundu iwiri, ndipo pamwamba pake imatha kukhala chrome-yokutidwa ndi utoto.
3. Pali kukana kwakukulu, kukana kutentha kwakukulu, kutentha kwa moto, kulimbikitsidwa, kuwonetsetsa ndi zina.
4. The fluidity ndi yoipa kwambiri kuposa HIPS, kuposa PMMA, PC, etc., ndipo imakhala yabwino kusinthasintha.
Ntchito: Zoyenera kupanga zida zamakina wamba, zochepetsera komanso zosamva kuvala, zida zotumizira ndi zida zamatelefoni.
Makhalidwe akuumba:
1.Amorphous zinthu, sing'anga fluidity, mkulu chinyezi mayamwidwe, ndipo ayenera kuuma kwathunthu.Zigawo zapulasitiki zomwe zimafuna gloss pamwamba ziyenera kutenthedwa ndi zouma kwa nthawi yaitali pa madigiri 80-90 kwa maola atatu.
2. Ndikoyenera kutenga kutentha kwakukulu kwa zinthu ndi kutentha kwa nkhungu, koma kutentha kwa zinthu kumakhala kokwera kwambiri komanso kosavuta kuwola (kutentha kwa kutentha ndi> 270 degrees).Pazigawo zapulasitiki zolondola kwambiri, kutentha kwa nkhungu kuyenera kukhala madigiri 50-60, omwe amalimbana ndi gloss yayikulu.Pazigawo za thermoplastic, kutentha kwa nkhungu kuyenera kukhala madigiri 60-80.
3. Ngati mukufuna kuthetsa kutsekera kwa madzi, muyenera kusintha madzi a zinthuzo, kutengera kutentha kwapamwamba, kutentha kwa nkhungu, kapena kusintha madzi ndi njira zina.
4. Ngati zinthu zosagwirizana ndi kutentha kapena moto zimapangidwira, zinthu zowonongeka za pulasitiki zidzakhalabe pamwamba pa nkhungu pambuyo pa masiku 3-7 kupanga, zomwe zidzachititsa kuti nkhungu ikhale yonyezimira, ndipo nkhungu iyenera kukhala yonyezimira. kutsukidwa mu nthawi, ndi nkhungu pamwamba ayenera kuonjezera malo utsi.
ABS resin ndiye polima yomwe ili ndi zotulutsa zazikulu kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri pakadali pano.Zimagwirizanitsa zinthu zosiyanasiyana za PS, SAN ndi BS, ndipo zimakhala ndi makina abwino kwambiri okhwima, okhwima, ndi okhwima.ABS ndi terpolymer wa acrylonitrile, butadiene ndi styrene.A imayimira acrylonitrile, B imayimira butadiene, ndipo S imayimira styrene.
Mapulasitiki a engineering a ABS nthawi zambiri amakhala opaque.Mawonekedwe ake ndi opepuka, opanda poizoni, komanso osakoma.Lili ndi makhalidwe a kuuma, kuuma ndi kusasunthika.Imayaka pang'onopang'ono, ndipo lawilo limakhala lachikasu ndi utsi wakuda.Pambuyo poyaka, pulasitiki imafewetsa ndikuyaka ndi kutulutsa mwapadera Fungo la sinamoni, koma palibe chodabwitsa chosungunuka ndi kudontha.
Mapulasitiki aukadaulo a ABS ali ndi zinthu zabwino kwambiri, mphamvu zowoneka bwino, kukhazikika kwa mawonekedwe, mphamvu zamagetsi, kukana kwa abrasion, kukana mankhwala, utoto, komanso kukonza bwino kwamawumbidwe ndi kukonza makina.Utoto wa ABS umalimbana ndi madzi, mchere wa inorganic, alkalis ndi zidulo.Sasungunuke m'ma alcohols ambiri ndi zosungunulira za hydrocarbon, koma zimasungunuka mosavuta mu aldehydes, ketoni, esters ndi ma hydrocarbons ena a chlorinated.
Kuipa kwa mapulasitiki a engineering a ABS: kutentha pang'ono kupotoza kutentha, kuyaka, komanso kukana kwanyengo.
