Kodi Pali Kusiyana Kotani Pakati pa PVC ndi PS Plastic?

Kodi PVC ndi yamphamvu kuposa PS? Kodi PS imamveka bwino kuposa PVC? Mapepala awiri apulasitikiwa amawoneka ofanana, koma amachita mosiyana kwambiri. PVC ndi yolimba. PS ndi yopepuka.
Mu positi iyi, muphunzira momwe mungawafanizire pakuyika, kumanga, ndi zina.

Kodi PVC Plastic ndi chiyani?

PVC imayimira polyvinyl chloride. Ndi imodzi mwazinthu zapulasitiki zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi. Nthawi zambiri mumazipeza m'mapaipi amipope, mafelemu a zenera, zotsekera chingwe, komanso machubu azachipatala. Chomwe chimapangitsa kuti ikhale yotchuka ndi mphamvu zake komanso kusinthasintha. Imagwira bwino motsutsana ndi mphamvu, chinyezi, ndi mankhwala ambiri.

Komanso mwachibadwa sichimayaka moto. Izi zikutanthauza kuti siziyatsa moto mosavuta, ndichifukwa chake omanga amakonda kuzigwiritsa ntchito pomanga ndi mawaya. Anthu amasankha PVC chifukwa ndi yotsika mtengo ndipo imagwira ntchito modalirika m'malo ambiri.

Pali mitundu iwiri ikuluikulu ya PVC. Imodzi ndi yosinthika, yotchedwanso PVC yapulasitiki. Mtunduwu umafewetsedwa powonjezera mapulasitiki, kotero ndikosavuta kupindika. Zimagwira ntchito bwino pamapaipi kapena zokutira chingwe. Mtundu winawo ndi wouma. Imadziwika kuti PVC kapena PVC yopanda pulasitiki. Ndi yolimba komanso yamphamvu, zomwe zimapangitsa kuti ikhale yabwino kwa mapaipi ndi zida zamapangidwe.

Akatswiri apanganso mitundu yapadera monga CPVC ndi PVC-O. CPVC imatha kuthana ndi madzi otentha bwino ndipo imagwiritsidwa ntchito pamapaipi apanyumba. PVC-O ili ndi mphamvu yowonjezereka kuchokera m'mene imakonzedwa, kotero ndi yabwino kwa mipope yothamanga kwambiri.

Nayi kuyang'ana mwachangu momwe mitunduyo ikufananizira:
