2,Polypropylene (PP).Ndiwopanda utoto komanso wowoneka bwino kapena imakhala ndi zinthu zina zowoneka bwino, zomwe zimatchedwa PP, zomwe zimadziwika kuti mphira wofewa.Ndi pulasitiki ya crystalline.Makhalidwe a polypropylene ndi awa.

a.Kuthamanga kwabwino komanso magwiridwe antchito abwino kwambiri.

b.Kukana kwabwino kwa kutentha, kumatha kutsukidwa ndikuwira pa madigiri 100 Celsius

c.High zokolola mphamvu;zabwino zamagetsi

d.Kusatetezeka kwamoto;kusowa kwa nyengo, kukhudzidwa ndi mpweya, kutengeka ndi kuwala kwa ultraviolet ndi ukalamba

3,Nylon (PA).Ndi pulasitiki ya engineering, ndi pulasitiki yopangidwa ndi polyamide resin, yotchedwa PA.pali PA6 PA66 PA610 PA1010, etc. Makhalidwe a nayiloni ndi awa.

a, nayiloni imakhala ndi crystallinity yayikulu, mphamvu zamakina apamwamba, kulimba kwabwino, kulimba kwambiri, kulimba mtima

b, kukana kutopa kwambiri, kukana kuvala, kukana dzimbiri, kukana kutentha, kusakhala ndi poizoni, zinthu zabwino kwambiri zamagetsi

c, kukana kuwala, kosavuta kuyamwa madzi, osamva acid

4,Polyformaldehyde (POM).Imadziwikanso kuti mtundu wazitsulo zachitsulo, ndi mtundu wa pulasitiki wauinjiniya.Makhalidwe ndi ntchito za polyformaldehyde

paraformaldehyde ili ndi mawonekedwe a crystalline kwambiri, imakhala ndi zida zabwino kwambiri zamakina, ma modulus apamwamba a elasticity, kulimba komanso kuuma kwapamtunda ndikwapamwamba kwambiri, komwe kumadziwika kuti "metal competitor"

b.Kukangana kwakung'ono, kukana kuvala bwino komanso kudzipaka mafuta, chachiwiri kwa nayiloni, koma kutsika mtengo kuposa nayiloni

c, zabwino zosungunulira kukana, makamaka zosungunulira organic, koma zidulo amphamvu, alkali amphamvu ndi oxidizers

d, kukhazikika kowoneka bwino, kumatha kupanga magawo olondola

e, akamaumba shrinkage, matenthedwe bata ndi osauka, Kutentha mosavuta kuwola

5,Acrylonitrile-butadiene-styrene (ABS).Pulasitiki ya ABS ndi polystyrene yosinthidwa mwamphamvu kwambiri, yopangidwa ndi acrylonitrile, butadiene ndi styrene mu chiŵerengero china cha mankhwala atatu, okhala ndi minyanga ya njovu yowala, opaque, yopanda poizoni ndi yopanda pake.

Makhalidwe ndi Ntchito

a.Mkulu wamakina mphamvu;kukana kwambiri kukhudza;kusungidwa bwino kwa kutentha;cholimba, cholimba, cholimba, etc.

b, Pamwamba pa zigawo za pulasitiki za ABS zitha kukutidwa

c, ABS akhoza blended ndi mapulasitiki ena ndi mphira kusintha ntchito zake, monga (ABS + PC)

6, Polycarbonate (PC).Galasi yomwe imadziwika kuti bulletproof, ndi yopanda poizoni, yopanda fungo, yopanda fungo, yowonekera, yoyaka, koma imatha kuzimitsa yokha ikachoka pamoto.Makhalidwe ndi ntchito.

a.Ndi kulimba kwapadera komanso kuuma kwapadera, imakhala ndi mphamvu yabwino kwambiri pakati pa zida zonse za thermoplastic

b.Kukaniza kwabwino kwambiri, kukhazikika bwino kwa mawonekedwe, kuwongolera kwakukulu;kutentha kwabwino (madigiri 120)

c.Zoyipa zake ndizochepa mphamvu zotopa, kupsinjika kwakukulu kwamkati, kosavuta kusweka, komanso kusamva bwino kwa zida zapulasitiki.

7,PC+ABS aloyi (PC+ABS).Kuphatikizika kwa PC (mapulasitiki opanga mainjiniya) ndi ABS (mapulasitiki acholinga chonse) zabwino zonse ziwiri, zidapangitsa magwiridwe antchito onse awiri.Muli ABS ndi PC mankhwala, ndi ABS fluidity wabwino ndi akamaumba processability, PC kukana mphamvu ndi kukana kutentha ndi kuzizira kusintha mkombero.Mawonekedwe

a.Itha kuperekedwa ndi guluu pakamwa / madzi akulu pakamwa nkhungu kapangidwe.

b, pamwamba akhoza sprayed mafuta, plating, zitsulo kutsitsi filimu.

c.Taonani kuwonjezera utsi pamwamba.

d.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimawunikidwa pamoto wothamanga ndipo zakhala zikugwiritsidwa ntchito pazinthu zambiri zolankhulirana ndi ogula, monga milandu yamafoni / makompyuta.
