Ngakhale zokutira zamapulasitiki zachikhalidwe zimakhala ndi zabwino zake kukhala zosavuta kuyeretsa komanso zolimba, mapulasitiki sizinthu zoteteza chilengedwe, ndipo sizosavuta kuzimbirira ndi kupasuka.
Pankhani yamakampani amakono a placemat, pang'onopang'ono adzasinthidwa ndi zinthu zoteteza zachilengedwe monga ulusi wapapepala wachilengedwe komanso ulusi wa thonje wopepuka umasinthidwa.
Kuopsa kwa zinthu zapulasitiki
1. Mukabwezeretsanso zinyalala zamapulasitiki, kusanja kumakhala kovuta kwambiri komanso kopanda chuma.
2. Pulasitiki ndi yosavuta kuwotcha ndipo imatulutsa mpweya wapoizoni ikawotchedwa.Mwachitsanzo, polystyrene ikawotchedwa, toluene imapangidwa.Kuchepa kwa mankhwalawa kungayambitse khungu, kupuma, kusanza ndi zizindikiro zina.
3. Mapulasitiki amapangidwa kuchokera kuzinthu zoyenga mafuta.Mafuta a petroleum ndi ochepa, zomwe sizikugwirizana ndi kugwiritsanso ntchito zinthu.
4. Pulasitiki sangathe kuwola mwachibadwa.
Ubwino ndi kuipa kwa nsalu za polyester
1. Ubwino wa nsalu yoyera ya thonje ndi yofewa komanso yomasuka kuvala, ndipo imakhala ndi mpweya wabwino kwambiri komanso chinyezi.Zoyipa zake ndikuti ndizosavuta kupunduka (kuchepera) ndikuzimiririka.Koma tsopano ndi chitukuko cha utoto wa nsalu ndi kumaliza ntchito, zathetsedwa.
2. Nsalu yoyera ya polyester imakhala ndi mpweya wochepa kwambiri komanso kutsekemera kwa chinyezi chifukwa cha hygroscopicity yake yovuta, koma mawonekedwe ake osungira mawonekedwe ndi abwino kwambiri.
3. Ubwino waukulu wa nsalu ya nayiloni ndikuti kukana kwake kuvala ndikwabwino kwambiri.
Kodi nsalu ya polyester ndi yotani?Kodi ubwino ndi kuipa kwake ndi chiyani?Ndipotu, ubwino ndi kuipa kwa nsalu za poliyesitala zimawonekeranso kwambiri, ndipo mitengo yake ndi yotsika mtengo, kuphatikizapo ubwino wokhala ndi mphamvu komanso yokhazikika, yosapunduka mosavuta, yosagwira dzimbiri, komanso yowuma mofulumira, amakondedwa kwambiri ndi msika.
Ubwino wa pepala chingwe zakuthupi
Chingwe cha pepala laumisiri chimapangidwa ndi pepala lapadera, lomwe ndi lamitundu yosiyanasiyana, lomangidwa mwamphamvu, lamphamvu kwambiri, lopepuka, losakhwima m'manja.2.Ili ndi zida zabwino kwambiri zoluka komanso zokhotakhota.Zitha kupangidwa kukhala ziwiri-strand, triple-strand ndi multistrand malinga ndi zofunika, ndi makulidwe chosinthika.3.Ili ndi ufulu wosankha mtundu, ndi mitundu yosiyanasiyana.Itha kugwiritsidwa ntchito kuluka kapena kumanga mtolo, pamwamba pake ndi yosalala, kuumba kumakwanira, ndipo mawonekedwe ake ndi okongola.Chifukwa chakuti zinthu zoterezi siziipitsa chilengedwe monga zinthu zapulasitiki, zimatchuka kwambiri kunja.
