Waya pulagi chuma chingwe mphamvu makamaka zikuphatikizapoPE (polyethylene), PP (polypropylene) ndi ABS (acrylonitrile-butadiene-styrene copolymer).
Zidazi zimasiyana muzochita zawo, ntchito ndi mawonekedwe.
1. PE (polyethylene) :
(1) Makhalidwe: PE ndi utomoni wa thermoplastic, wopanda poizoni komanso wopanda vuto, kukana kutentha kwapang'onopang'ono, katundu wabwino kwambiri wamagetsi ndi zinthu zina. Lilinso ndi makhalidwe otsika kutayika ndi mkulu conductive mphamvu, choncho nthawi zambiri ntchito monga insulating zakuthupi mkulu voteji waya ndi chingwe. Kuphatikiza apo, zida za PE zili ndi mawonekedwe abwino amagetsi ndipo zimagwiritsidwa ntchito kwambiri mu mawaya a coaxial ndi zingwe zomwe zimafuna kutsika kwa waya.
(2) Kugwiritsa ntchito: Chifukwa cha mphamvu zake zabwino kwambiri zamagetsi, PE imagwiritsidwa ntchito nthawi zambiri muzitsulo za waya kapena chingwe, zipangizo zotetezera waya, ndi zina zotero.
2. PP (polypropylene) :
(1) Makhalidwe: Makhalidwe a PP akuphatikizapo elongation yaying'ono, osasunthika, tsitsi lofewa, kuthamanga kwamtundu wabwino komanso kusoka kosavuta. Komabe, kukoka kwake kumakhala kocheperako. Kugwiritsa ntchito kutentha kwa PP ndi -30 ℃ ~ 80 ℃, ndipo mawonekedwe ake amagetsi amatha kupitilizidwa ndi thovu.
(2) Kugwiritsa ntchito: PP zakuthupi ndizoyenera mitundu yonse ya waya ndi chingwe, monga chingwe chamagetsi ndi waya wamagetsi, ndikukwaniritsa zofunikira za UL, zimatha kukhala popanda mfundo.
3. ABS (acrylonitrile-butadiene-styrene copolymer) :
(1) Makhalidwe: ABS ndi thermoplastic polima zakuthupi kapangidwe ndi mphamvu mkulu, kulimba wabwino ndi kukonza mosavuta. Ili ndi ubwino wa acrylonitrile, butadiene ndi styrene monomers atatu, kotero kuti imakhala ndi kukana kwa dzimbiri kwa mankhwala, kukana kutentha, kuuma kwapamwamba komanso kusungunuka kwakukulu ndi kulimba.
(2) Kugwiritsa ntchito: ABS nthawi zambiri imagwiritsidwa ntchito pamapulogalamu omwe amafunikira mphamvu yayikulu komanso kulimba, monga zida zamagalimoto, zotchingira zamagetsi, ndi zina zambiri. Pankhani ya zingwe zamagetsi, ABS imagwiritsidwa ntchito nthawi zambiri kupanga ma insulators ndi nyumba.
Mwachidule, PE, PP ndi ABS ali ndi ubwino wawo ndi zochitika zogwiritsira ntchito mu zipangizo zamapulagi zamawaya a zingwe zamagetsi. PE imagwiritsidwa ntchito kwambiri pakutchinjiriza waya ndi chingwe chifukwa champhamvu zake zamagetsi zamagetsi komanso kukana kutentha kochepa. PP ndi yoyenera kwa mitundu yosiyanasiyana ya waya ndi chingwe chifukwa cha kufewa kwake ndi kufulumira kwa mtundu wabwino; ABS, yokhala ndi mphamvu zambiri komanso kulimba kwake, imagwiritsidwa ntchito kutsekereza zida zamagetsi ndi zingwe zamagetsi zomwe zimafunikira izi.
Momwe mungasankhire zida zoyenera kwambiri za PE, PP ndi ABS malinga ndi zofunikira za chingwe chamagetsi?
Posankha zipangizo zoyenera kwambiri za PE, PP ndi ABS, m'pofunika kuganizira mozama zofunikira za chingwe chamagetsi.
1. Zinthu za ABS:
(1) Makina amakina: Zinthu za ABS zili ndi mphamvu zambiri komanso kuuma, ndipo zimatha kupirira katundu wamkulu wamakina.
(2) Pamwamba gloss ndi processing ntchito: ABS zinthu ali ndi gloss wabwino pamwamba ndi processing ntchito, amene ali oyenera kupanga magetsi mzere nyumba kapena pulagi mbali ndi mkulu maonekedwe zofunika ndi kukonza bwino.
2. PP zinthu:
(1) Kutentha kwa kutentha, kukhazikika kwa mankhwala ndi kuteteza chilengedwe: Zinthu za PP zimadziwika chifukwa cha kutentha kwake, kukhazikika kwa mankhwala ndi kuteteza chilengedwe.
(2) Kutchinjiriza magetsi: PP ali kwambiri kutchinjiriza magetsi, angagwiritsidwe ntchito mosalekeza pa 110 ℃-120 ℃, oyenera kusanjikiza mkati kutchinjiriza chingwe mphamvu kapena ngati m'chimake chuma cha waya.
(3) Minda yofunsira: PP imagwiritsidwa ntchito kwambiri pazida zam'nyumba, zonyamula katundu, mipando, zinthu zaulimi, zomanga ndi minda ina, kuwonetsa kuti ili ndi magwiridwe antchito komanso odalirika.
3, PE zinthu:
(1) Kukana kwa dzimbiri: Pepala la PE lili ndi kukana kwa dzimbiri ndipo limatha kukhala lokhazikika pama media azamankhwala monga asidi ndi alkali.
(2) Kusungunula ndi kuyamwa kwamadzi otsika: Pepala la PE limakhala ndi kutsekemera kwabwino komanso kuyamwa kwamadzi otsika, kupanga pepala la PE limagwira ntchito wamba m'magawo amagetsi ndi zamagetsi.
(3) Kusinthasintha ndi kukana kwamphamvu: Pepala la PE limakhalanso ndi kusinthasintha kwabwino komanso kukana kwamphamvu, koyenera kutetezedwa kwakunja kwa chingwe chamagetsi kapena ngati chotchinga cha waya kuti chikhale cholimba komanso chitetezo.
Ngati chingwe chamagetsi chimafunikira mphamvu yayikulu komanso kuwala kowala bwino, zinthu za ABS zitha kukhala chisankho chabwino kwambiri;
Ngati chingwe chamagetsi chimafuna kukana kutentha, kukhazikika kwamankhwala ndi kuteteza chilengedwe, zinthu za PP ndizoyenera;
Ngati chingwe chamagetsi chikufunika kukana dzimbiri, kutsekemera komanso kuyamwa kwamadzi otsika, zinthu za PE ndi chisankho chabwino.
