Zipangizo zapulasitiki za ABS

Dzina la mankhwala: Acrylonitrile-butadiene-styrene copolymer
Dzina la Chingerezi: Acrylonitrile Butadiene Styrene
Mphamvu yokoka: 1.05 g/cm3 Kuchepa kwa nkhungu: 0.4-0.7%
Kutentha kwa kuumba: 200-240℃ Mikhalidwe youma: 80-90℃ maola awiri
Mawonekedwe:
1. Kugwira ntchito bwino, mphamvu yogwira ntchito kwambiri, kukhazikika kwa mankhwala, komanso mphamvu zamagetsi zabwino.
2. Ili ndi kuthekera kolumikizana bwino ndi 372 plexiglass ndipo imapangidwa ndi pulasitiki yamitundu iwiri, ndipo pamwamba pake pakhoza kukhala yokutidwa ndi chrome ndikupakidwa utoto.
3. Pali kukana kwakukulu, kukana kutentha kwambiri, kuletsa moto, kulimbitsa, kuwonekera bwino ndi zina.
4. Kusinthasintha kwake kumakhala koipa pang'ono kuposa ma HIPS, kuposa PMMA, PC, ndi zina zotero, ndipo kumakhala kosinthasintha bwino.
Ntchito: yoyenera kupanga zida zonse zamakanika, zida zochepetsera komanso zosagwira ntchito, zida zotumizira ndi zida zolumikizirana.
Makhalidwe oumbira:
1. Zinthu zopanda mawonekedwe, madzi apakati, chinyezi chambiri, ndipo ziyenera kuuma kwathunthu. Zigawo za pulasitiki zomwe zimafuna kuwala pamwamba ziyenera kutenthedwa ndi kuuma kwa nthawi yayitali pa madigiri 80-90 kwa maola atatu.
2. Ndikoyenera kutenga kutentha kwakukulu kwa zinthu ndi kutentha kwakukulu kwa nkhungu, koma kutentha kwa zinthuzo ndi kwakukulu kwambiri ndipo n'kosavuta kuwola (kutentha kwa kuwonongeka ndi madigiri >270). Pazigawo zapulasitiki zomwe zili ndi kulondola kwakukulu, kutentha kwa nkhungu kuyenera kukhala madigiri 50-60, komwe kumalimbana ndi kuwala kwambiri. Pazigawo za thermoplastic, kutentha kwa nkhungu kuyenera kukhala madigiri 60-80.
3. Ngati mukufuna kuthetsa vuto la kutsekeka kwa madzi, muyenera kusintha madzi kuti zinthuzo ziyende bwino, kugwiritsa ntchito kutentha kwambiri kwa zinthuzo, kutentha kwambiri kwa nkhungu, kapena kusintha kuchuluka kwa madzi ndi njira zina.
4. Ngati zinthu zosatentha kapena zoletsa moto zapangidwa, zinthu zowola za pulasitiki zidzakhalabe pamwamba pa nkhungu patatha masiku 3-7 kuchokera pamene zapangidwa, zomwe zimapangitsa kuti pamwamba pa nkhungu pakhale powala, ndipo nkhunguyo iyenera kutsukidwa nthawi yake, ndipo pamwamba pa nkhunguyo payenera kuwonjezera malo otulutsira utsi.
Utomoni wa ABS ndi polima yomwe imatulutsa mphamvu zambiri komanso yomwe imagwiritsidwa ntchito kwambiri pakadali pano. Imagwirizanitsa zinthu zosiyanasiyana za PS, SAN ndi BS, ndipo ili ndi mphamvu zabwino kwambiri zamakina monga kulimba, kulimba, komanso kulimba. ABS ndi terpolymer ya acrylonitrile, butadiene ndi styrene. A imayimira acrylonitrile, B imayimira butadiene, ndipo S imayimira styrene.
Mapulasitiki a ABS nthawi zambiri amakhala osawoneka bwino. Mawonekedwe ake ndi a mnyanga wopepuka, osapsa, komanso opanda kukoma. Ali ndi mawonekedwe olimba, olimba komanso osasunthika. Amayaka pang'onopang'ono, ndipo lawi lake ndi lachikasu ndi utsi wakuda. Pambuyo poyaka, pulasitikiyo imafewa ndikuyaka ndi kutulutsa fungo lapadera la sinamoni, koma palibe kusungunuka kapena kudontha madzi.
Mapulasitiki aukadaulo a ABS ali ndi makhalidwe abwino kwambiri, mphamvu yabwino kwambiri yokhudza, kukhazikika bwino kwa mawonekedwe, mphamvu zamagetsi, kukana kukwawa, kukana mankhwala, kukana utoto, komanso kukonza bwino mapangidwe ndi makina. Utomoni wa ABS umalimbana ndi madzi, mchere wosapangidwa, alkalis ndi asidi. Susungunuka m'ma alcohols ambiri ndi ma hydrocarbon solvents, koma umasungunuka mosavuta mu aldehydes, ketones, esters ndi ma hydrocarbon ena a chlorine.
Zoyipa za mapulasitiki aukadaulo a ABS: kutentha kochepa kosokoneza kutentha, kuyaka, komanso kukana nyengo.
