Chiyambi cha Katundu wa ABS ndi Njira Zosinthira

Utomoni wa ABS ndi acrylonitrile-butadiene-styrene copolymer, monga imodzi mwa mitundu ya pulasitiki yokhala ndi magwiridwe antchito apamwamba kwambiri, mbali imodzi ya ABS, ntchito zamsika zikutsegulidwa, kumbali ina, kudzera mu chitukuko cha mitundu yatsopano ndi kusintha kwaukadaulo ndi kafukufuku wa alloy, ikukulirakulira kukhala yachisanu ndi chimodzi yayikulu, makamaka kudzera mu kusintha, ABS imatulutsa mitundu yatsopano yambiri. Ikhoza kusakanikirana ndi mitundu yosiyanasiyana ya utomoni kuti ipange alloys, yokhala ndi mitundu yambiri komanso ntchito zambiri, ndipo ndi imodzi mwa mapulasitiki akuluakulu aukadaulo.

Katundu wa ABS

ABS ndi utomoni wopepuka wachikasu kapena wopepuka wopangidwa ndi mikanda, wopanda poizoni, wopanda kukoma, wonyowa madzi pang'ono, uli ndi makhalidwe abwino akuthupi komanso amakina, monga mphamvu zamagetsi zabwino, kukana kuwonongeka, kukhazikika kwa mawonekedwe, kukana mankhwala ndi mawonekedwe a gloss, komanso kupangika kosavuta. Vuto lake ndi kukana nyengo, kukana kutentha, komanso kukana kuyaka.

ABS plastikikatundu wamakina

ABS ili ndi mphamvu zabwino kwambiri zamagetsi, mphamvu yake yogwira ntchito ndi yabwino kwambiri ndipo ingagwiritsidwe ntchito kutentha kochepa kwambiri; ABS ili ndi mphamvu yabwino kwambiri yotha kutha, kukhazikika bwino kwa mawonekedwe, komanso kukana mafuta, ndipo ingagwiritsidwe ntchito pa mabearing pansi pa katundu wapakati ndi liwiro. Mphamvu za makina a ABS zimakhudzidwa ndi kutentha.

Mitundu ya ABS yogwiritsira ntchito

ABS yonyezimira kwambiri imagwiritsidwa ntchito pa zotsukira vacuum, mafani amagetsi, ma air conditioner, mafoni ndi zinthu zina zapakhomo, zomwe zimafikiridwa poyang'anira kukula kwa tinthu ta rabara R+ (tochepa) mu ABS. ABS yonyezimira yochepa imagwiritsidwa ntchito pa ma dashboard, zophimba zida, zipilala ndi zina zamkati mwa magalimoto, zomwe zimadzazidwa ndi zodzaza zolimba kuti zichepetse mawonekedwe akunja ndikuchepetsa kuwala kwakunja.

Mitundu ndi makhalidwe a ABS

ABS yosapsa moto (yoletsa moto) ya mtundu wa ABS:

ABS ndi chinthu choyaka moto, malinga ndi UL94 specification ndi ya HB level. ABS imazima mwachangu ikagwira moto, ndipo imatulutsa mpweya wambiri wapoizoni ndi utsi wakuda, zomwe sizikugwirizana ndi kugwiritsidwa ntchito kwenikweni. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso moyo wabwino, chidziwitso cha anthu cha chitetezo chikukulirakulira, kugwiritsa ntchito magalimoto, zomangamanga, zida zapakhomo, ndi zina mwazinthu zapulasitiki kukuyika patsogolo zofunikira zolimbana ndi moto, kukulitsa ma specifications ndi miyezo yofananira, motero kafukufukuyu ali ndi tanthauzo lalikulu.
Njira zitatu zazikulu zochepetsera kuzimitsidwa kwa ma resins a ABS:

1. Gwiritsani ntchito ma polima oletsa moto kuti musakanize ndi ABS, monga CPE, PVC;

2. Kusintha kwa mankhwala a ABS yomwe ilipo, monga kutenga nawo mbali kwa styrene ya tribrominated ngati monomer yachinayi yokonzekera ABS ya magawo anayi;

3. Kudzera mu njira yodziwika bwino ya ABS kuti mutenge nawo mbali, kuphatikizapo zinthu zoletsa moto zosapangidwa ndi zinthu zachilengedwe (monga MoO3) ndi zinthu zoletsa moto zachilengedwe (monga zinthu za halogen, zinthu zoletsa moto za phosphorous). Mtundu wa zinthu zoletsa moto uli ndi mphamvu yoletsa moto bwino, koma zinthu zina zingakhale zoipa (monga kukalamba, mtengo wokwera). ABS yosinthidwa ndi mankhwala imafuna njira inayake yogwiritsira ntchito komanso njira yovuta kwambiri. Njira yachitatu imapeza mgwirizano pakati pa mtengo ndi magwiridwe antchito ndipo ndi yothandiza kwambiri popanga zinthu zambiri. Pakadali pano, kusintha kwa zinthu za ABS zomwe zimaletsa moto kumadalira kuwonjezera zinthu zoletsa moto zomwe zili ndi halogen.
