Pansi pa pulasitiki amatha kugawidwa m'mitundu iwiri malinga ndi momwe amagwiritsidwira ntchito: zida zotchinga (kapena matailosi pansi) ndi zida zopukutira (kapena pepala lapansi).Malinga ndi zinthu zake, imatha kugawidwa m'mitundu itatu: yolimba, yolimba, komanso yofewa (yotanuka).Malinga ndi zida zake zopangira, imatha kugawidwa m'mitundu ingapo, kuphatikiza pulasitiki ya polyvinyl chloride (PVC), polypropylene (PP) pulasitiki ndi thermoplastic.
Chifukwa cha kukana kwabwino kwa lawi lamoto komanso zozimitsa zokha za PVC, ndipo magwiridwe ake atha kusinthidwa posintha kuchuluka kwa mapulasitiki ndi zodzaza zowonjezeredwa, pulasitiki ya PVC ndiyomwe imagwiritsidwa ntchito kwambiri pakadali pano.
Polyvinyl chloride (PVC) ndi polima wopangidwa kuchokera ku petroleum, gasi wachilengedwe ndi zida zina zopangira pogwiritsa ntchito mankhwala okhwima.PVC ali ndi makhalidwe a fireproof, madzi, odana ndi dzimbiri, etc., ndipo n'zosavuta pokonza ndi mawonekedwe, choncho chimagwiritsidwa ntchito pansi, zomangira ndi madera ena.Zida za PVC zimapangidwa ndi utomoni wa polyvinyl chloride monga thupi lalikulu, losakanikirana ndi zinthu zosiyanasiyana zodzaza, zowonjezera ndi zina zopangira.Zinthuzi zimafunidwa ndi anthu chifukwa cha zabwino zake zosiyanasiyana, makamaka pamakampani opanga pansi.Chifukwa cha ubwino wake kuteteza chilengedwe, madzi, odana kuzembera, odana malo amodzi, kupewa moto, kutchinjiriza phokoso, kuvala kukana, etc., PVC pansi wakhala kusankha ambiri m'minda ya zomangamanga mafakitale ndi malonda, kukongoletsa nyumba ndi magalimoto. .
Makhalidwe a PVC pansi ndi awa:
1.Kuteteza chilengedwe: Zida za pansi pa PVC sizidzatulutsa mpweya wapoizoni ndi woopsa zikagwiritsidwa ntchito, sizidzapanga magetsi osasunthika, ndipo zimakhala ndi moyo wautali wautumiki kuposa zipangizo zamakono.
2. Kukana kwa abrasion: Zinthu zapansi za PVC zapaka utoto ndipo zimatetezedwa ndi UV, ndipo zimakhala ndi kukana kwabwino kwa kuvala, zomwe zingathe kukwaniritsa zofunikira zamalonda ndi malo ogulitsa mafakitale.
3. Anti-slip katundu: Pamwamba pa zinthu za PVC pansi zakonzedwa ndipo zimakhala ndi ntchito zabwino zotsutsana ndi zowonongeka, zomwe zimapangitsa kuti zikhale zovuta kuti mutengeke ndi kugwa m'moyo watsiku ndi tsiku ndi ntchito, kuonetsetsa chitetezo.
4. Opepuka: Pansi PVC utenga kamangidwe opepuka, amene n'zosavuta pokonza, yabwino kuyala, ndi yabwino kusamalira ndi kuyeretsa.
5.Corrosion resistance: PVC pansi ili ndi asidi wabwino ndi kukana kwa alkali, sichidzawonongeka ndi zinthu zamakina ndi mphamvu yamakina, imachepetsa mwayi wodetsa, komanso imakhala yoyera.
