Kodi pali kusiyana kotani pakati pa pe, pp, abs?

Mtengo waya wa waya umaphatikizapoPe (polyethylene), PP (Polypropylene) ndi abs (acrylonile-butadiene-styrene cololymer).

Zipangizozi zimasiyana mu katundu wawo, mapulogalamu ndi mawonekedwe ake.
1. Pe (polyethylene) :
. Ilinso ndi mawonekedwe otayika pang'ono komanso kukhala ndi mphamvu zambiri, motero nthawi zambiri imagwiritsidwa ntchito ngati zinthu zowonjezera za waya wamphamvu kwambiri ndi chingwe. Kuphatikiza apo, zojambulajambula zimakhala ndi magetsi abwino ndipo zimagwiritsidwa ntchito ngati zingwe zophatikizika ndi zingwe zofunika kwambiri.
.

2. PP (Polypropylene):
. Komabe, kukoka kwake kumakhala kochepa kwambiri. Kugwiritsa ntchito kutentha kwa PP ndi -30 ℃ ~ 80 ℃, ndipo mawonekedwe ake amagetsi amatha kusintha mwa kumenyedwa.
.

3.
. Ili ndi ma hirylonios a acarylonile, acadiene ndi styrene atatu monomers, kotero kuti ikutsutsana ndi mankhwala, kukana kutentha, kukhazikika kwamphamvu komanso kulimba mtima.
.

Mwachidule, pe, mas, ma pp ndi ma pp ndi malo ogwiritsira ntchito mu waya amapangira zingwe za magetsi. PE imagwiritsidwa ntchito kwambiri mu waya ndi chingwe chosasunthika chifukwa cha magetsi abwino kwambiri osokoneza magetsi ndi kutentha kwakanthawi. PP ndi yoyenera kwa waya wamitundu yosiyanasiyana ndi chithokomiro chifukwa chofewa komanso utoto wabwino kutengedwa; Abs, ndi mphamvu zake zazikulu komanso mphamvu yake, imagwiritsidwa ntchito kuphatikiza zigawo zamagetsi ndi mizere yamagetsi yomwe imafunikira mawonekedwe awa.

Kodi mungasankhe bwanji zigawo zoyenera kwambiri pa mas, ma pp molingana ndi zomwe mukufuna kugwiritsa ntchito chingwe champhamvu?

Mukamasankha zigawo zoyenera kwambiri, ma pp ndi ofunikira kuganizira zomwe zalembedwa munjira ya chingwe.
1. ABS:
(1) Zopangira: Zinthu zaluso zili ndi mphamvu zambiri komanso kuuma, ndipo zimatha kupirira katundu wamkulu.
.

2. Zithunzi za PP:

3, Pepala:

Ngati chingwe champhamvu chimafunikira mphamvu yayikulu komanso yabwino kwambiri, mabudawa atha kukhala chisankho chabwino kwambiri;
Ngati mphamvu yamphamvu imafunikira kukana kutentha, kukhazikika kwamankhwala ndi kutetezedwa kwa chilengedwe, zinthu za mabus ndizoyenera;
Ngati mphamvu yamagetsi imafunikira kukana kuwonongeka, kutchinga ndi madzi otsekemera madzi, pempho ndi chisankho chabwino.
