Kodi kusankha zoyenera kuwotcherera zakuthupi?

Monga tonse tikudziwa, sizinthu zonse zapulasitiki zomwe zimatha kuwotcherera ndimakina owotcherera pulasitiki akupanga.Mwachitsanzo, ngati kusungunuka kwa mitundu iwiri ya zipangizo pulasitiki ndi lalikulu kwambiri, akupanga kuwotcherera ndondomeko n'kovuta ndi kuwotcherera zotsatira si zabwino choncho, m'pofunika kudziwa za akupanga kuwotcherera zipangizo.

Ambiri ntchito pulasitiki zinthu makhalidwe

Nazi zina zomwe zimagwiritsidwa ntchito pulasitiki ndi mawonekedwe ake

ABS: Acrylonitrile butadiene styrene copolymer, yomwe imatchedwanso ABS, mphamvu yokoka ndi yopepuka, ndipo Abs imakhala ndi matenthedwe abwino amafuta, ndiyoyenera makamaka kuwotcherera akupanga pulasitiki.

PS: polystyrene, mphamvu yokoka ndi yopepuka, imakhala ndi kukana kwamphamvu kwa dzimbiri motsutsana ndi madzi ndi mankhwala, ndi kukhazikika kwapamwamba komanso kutsekemera kwabwino, PS ndiyoyenera kwambiri jekeseni ndi kupanga extrusion.Nthawi zambiri amagwiritsidwa ntchito muzoseweretsa, zokongoletsa, zida zotsuka mbale, mandala, mawilo oyandama ndi zinthu zina.Chifukwa champhamvu zotanuka mphamvu coefficient, ndi oyenera akupanga kuwotcherera ndondomeko.

Acrylic, Acrylic products ali ndi kuuma kwakukulu komanso kukana kwamphamvu, sikungakhudzidwe ndi asidi, ndipo kuwala kwa kuwala kumakhala kwakukulu, choncho nthawi zambiri amagwiritsidwa ntchito pazitsulo zam'mbuyo zamagalimoto, bolodi lotanthawuza, MEDALS, mapaipi, ndi zina zotero.

Aceta: Imakhala ndi kukana kwamphamvu kwambiri komanso mphamvu yayikulu yopondereza komanso kukana kuvala bwino, imagwiritsidwa ntchito kwambiri pophunzitsa, zomangira, zomangira, zogudubuza, ziwiya zakukhitchini, ndi zina zambiri, Chifukwa cha kuchepa kwapang'onopang'ono, njira yowotcherera ya akupanga imafunikira kugwedezeka kwakukulu komanso kutalika. nthawi yowotcherera.

Ma celluloeics: pamene akupanga kuwotcherera makina ntchito, chifukwa cha akupanga kugwedera, zinthu mtundu n'zosavuta kusintha, ndi kukhudzana pamwamba si kophweka kuyamwa mphamvu, kotero akupanga kuwotcherera ndondomeko zovuta.

PP: polypropylene amatchedwanso PP, mphamvu yokoka yeniyeni ndi yopepuka, ndipo imakhala ndi kutchinjiriza bwino, mphamvu yayikulu, kukana kutentha ndi kukokoloka kwamankhwala, pambuyo poti waya angapangidwe kukhala chingwe ndi nsalu zina.PP Zogulitsa ndi zoseweretsa, katundu, chipolopolo cha nyimbo, kutchinjiriza kwamagetsi, kunyamula chakudya ndi zina zotero.Chifukwa cha kuchepa kwake kwa zotanuka, zinthuzo ndizosavuta kuyimitsa kugwedezeka kwamayimbidwe ndipo zimakhala zovuta kuwotcherera.

Zinthu zabwino zowotcherera:

ABS: Acrylonitrile butadiene styrene copolymer, yotchedwa ABS;Nkhaniyi ndi yowotcherera, koma mtengo wazinthuzi ndi wokwera mtengo.ABS ili ndi ubwino wa kukana kwakukulu, kukana kutentha kwakukulu, kutentha kwa moto, kupititsa patsogolo ndi kuwonekera;chimagwiritsidwa ntchito kwambiri mu makina, galimoto, zida zamagetsi, zida, nsalu ndi zomangamanga ndi minda ina mafakitale, ndi osiyanasiyana kwambiri mapulasitiki thermoplastic engineering.

PS: mphamvu yokoka ndi yopepuka, imakhala ndi kukana kwamphamvu kwa dzimbiri motsutsana ndi madzi ndi mankhwala, kukhazikika kwapamwamba komanso kutchinjiriza kwabwino, chifukwa chake ndikoyenera kuwotcherera akupanga.

SNA: Akupanga kuwotcherera zotsatira zabwino.

Zovuta weld zakuthupi

PPS: Ndizovuta kwambiri kuwotcherera chifukwa zinthu zake ndi zofewa kwambiri.

PE: Polyethylene, yotchedwa PE;Zinthuzi ndi zofewa moti zimakhala zovuta kuwotcherera

PVC: Polyvinyl kolorayidi, wotchedwa PVC;Zinthuzo ndi zofewa komanso zovuta kuwotcherera, kotero anthu ochepa amagwiritsa ntchito zinthu zamtunduwu, zomwe zimapangidwa ndi zinthuzi nthawi zambiri zimagwiritsa ntchito ma frequency apamwamba kuwotcherera.

PC: Polycarbonate, malo osungunuka ndi okwera, choncho amafunikira nthawi yochulukirapo kuti awotchere.

PP: Polypropylene, Zinthu zake ndizovuta kuziwotcherera chifukwa chocheperako komanso kutsika kosavuta kwa kugwedezeka kwamayimbidwe.

Zida zina monga PA, POM(Polyoxymethylene).PMM(Polymethyl methacrylate),A/S(Acrylonitrile-styrene copolymer), PETP(polybutylene terephthalate) ndi

PBTP (polyethylene terephthalate) ndi zovuta kugwiritsa ntchito akupanga kuwotcherera kwa kuwotcherera.
