Zipangizo za waya zomwe zimagwiritsidwa ntchito pa chingwe chamagetsi zimaphatikizapoPE (polyethylene), PP (polypropylene) ndi ABS (acrylonitrile-butadiene-styrene copolymer).
Zipangizozi zimasiyana malinga ndi makhalidwe awo, ntchito zawo, ndi makhalidwe awo.
1. PE (polyethylene) :
(1) Makhalidwe: PE ndi utomoni wa thermoplastic, wopanda poizoni komanso wosavulaza, woteteza kutentha pang'ono, wokhala ndi mphamvu zabwino kwambiri zotetezera magetsi ndi zina. Ilinso ndi makhalidwe a kutayika kochepa komanso mphamvu yayikulu yoyendetsa magetsi, kotero nthawi zambiri imagwiritsidwa ntchito ngati zinthu zotetezera magetsi pa waya ndi chingwe chokhala ndi magetsi ambiri. Kuphatikiza apo, zipangizo za PE zili ndi makhalidwe abwino amagetsi ndipo zimagwiritsidwa ntchito kwambiri mu mawaya a coaxial ndi zingwe zomwe zimafuna mphamvu yochepa ya waya.
(2) Kugwiritsa Ntchito: Chifukwa cha mphamvu zake zamagetsi zabwino kwambiri, PE nthawi zambiri imagwiritsidwa ntchito poteteza waya kapena chingwe, zinthu zoteteza waya wa data, ndi zina zotero. PE ingathandizenso kuletsa moto mwa kuwonjezera zinthu zoletsa moto.
2. PP (polypropylene):
(1) Makhalidwe: Makhalidwe a PP ndi monga kutalika pang'ono, kusasinthasintha, tsitsi lofewa, kulimba kwa utoto wabwino komanso kusoka kosavuta. Komabe, kukoka kwake ndi kochepa. Kutentha kwa PP komwe kumagwiritsidwa ntchito ndi -30℃ ~ 80℃, ndipo mawonekedwe ake amagetsi amatha kusinthidwa ndi thovu.
(2) Kugwiritsa Ntchito: Zipangizo za PP ndizoyenera mitundu yonse ya waya ndi chingwe, monga chingwe chamagetsi ndi waya wamagetsi, ndipo zimakwaniritsa zofunikira za mphamvu yosweka ya UL, ndipo sizingakhale ndi malo olumikizirana.
3. ABS (acrylonitrile-butadiene-styrene copolymer):
(1) Makhalidwe: ABS ndi kapangidwe ka zinthu za thermoplastic polymer komwe kali ndi mphamvu zambiri, kulimba bwino komanso kosavuta kukonza. Ili ndi ubwino wa acrylonitrile, butadiene ndi styrene three monomers, kotero kuti imakhala ndi kukana dzimbiri kwa mankhwala, kukana kutentha, kuuma pamwamba kwambiri komanso kusinthasintha kwakukulu komanso kulimba.
(2) Kugwiritsa Ntchito: ABS nthawi zambiri imagwiritsidwa ntchito pazinthu zomwe zimafuna mphamvu zambiri komanso kulimba, monga zida zamagalimoto, zomangira zamagetsi, ndi zina zotero. Ponena za zingwe zamagetsi, ABS nthawi zambiri imagwiritsidwa ntchito popanga zotetezera kutentha ndi zophimba kutentha.
Mwachidule, PE, PP ndi ABS zili ndi ubwino wawo komanso momwe zimagwiritsidwira ntchito pazinthu zopangira ma waya a zingwe zamagetsi. PE imagwiritsidwa ntchito kwambiri poteteza mawaya ndi zingwe chifukwa cha mphamvu zake zabwino zotetezera magetsi komanso kukana kutentha kwambiri. PP ndi yoyenera mitundu yosiyanasiyana ya mawaya ndi zingwe chifukwa cha kufewa kwake komanso kulimba kwa utoto; ABS, yokhala ndi mphamvu zambiri komanso kulimba, imagwiritsidwa ntchito poteteza zigawo zamagetsi ndi zingwe zamagetsi zomwe zimafunikira makhalidwe awa.
Kodi mungasankhe bwanji zipangizo zoyenera kwambiri za PE, PP ndi ABS malinga ndi zofunikira pakugwiritsa ntchito chingwe chamagetsi?
Posankha zipangizo zoyenera kwambiri za PE, PP ndi ABS, ndikofunikira kuganizira mokwanira zofunikira pakugwiritsa ntchito chingwe chamagetsi.
1. Zinthu za ABS:
(1) Kapangidwe ka makina: Zipangizo za ABS zili ndi mphamvu zambiri komanso kuuma, ndipo zimatha kupirira katundu waukulu wa makina.
(2) Kugwira ntchito bwino kwa gloss ndi kukonza pamwamba: Zipangizo za ABS zili ndi ntchito yabwino kwambiri yokongoletsa pamwamba ndi kukonza, zomwe ndizoyenera kupanga nyumba yamagetsi kapena zida zolumikizira zomwe zimafunikira mawonekedwe apamwamba komanso kukonza bwino.
2. Zinthu za PP:
(1) Kukana kutentha, kukhazikika kwa mankhwala ndi kuteteza chilengedwe: Zipangizo za PP zimadziwika ndi kukana kutentha bwino, kukhazikika kwa mankhwala ndi kuteteza chilengedwe.
(2) Chotetezera magetsi: PP ili ndi chotetezera magetsi chabwino kwambiri, chingagwiritsidwe ntchito mosalekeza pa 110℃-120℃, choyenera kutetezera magetsi mkati mwa chingwe chamagetsi kapena ngati chida chotetezera waya.
(3) Magawo ogwiritsira ntchito: PP imagwiritsidwa ntchito kwambiri pazida zapakhomo, zinthu zolongedza, mipando, zinthu zaulimi, zinthu zomangira ndi zina, zomwe zikusonyeza kuti ili ndi mitundu yosiyanasiyana yogwiritsira ntchito komanso yodalirika.
3, PE zakuthupi:
(1) Kukana dzimbiri: Pepala la PE lili ndi kukana dzimbiri kwabwino kwambiri ndipo limatha kukhala lolimba muzinthu monga asidi ndi alkali.
(2) Kuteteza kutentha ndi kuyamwa madzi pang'ono: Pepala la PE lili ndi kutetezera kutentha bwino komanso kuyamwa madzi pang'ono, zomwe zimapangitsa kuti pepala la PE ligwiritsidwe ntchito kwambiri m'magawo amagetsi ndi zamagetsi.
(3) Kusinthasintha ndi kukana kugunda: Pepala la PE lilinso ndi kusinthasintha kwabwino komanso kukana kugunda, loyenera kuteteza chingwe chamagetsi kapena ngati chida chotetezera waya kuti ukhale wolimba komanso wotetezeka.
Ngati chingwe chamagetsi chikufunika mphamvu zambiri komanso kuwala kwabwino pamwamba, zinthu za ABS zitha kukhala chisankho chabwino kwambiri;
Ngati chingwe chamagetsi chikufunika kukana kutentha, kukhazikika kwa mankhwala komanso kuteteza chilengedwe, zinthu za PP ndizoyenera kwambiri;
Ngati chingwe chamagetsi chikufunika kukana dzimbiri, kutchinjiriza komanso kusayamwa madzi ambiri, zinthu za PE ndi chisankho chabwino kwambiri.
