Ubwino wa mapaipi a PVC

Mapaipi a PVC amatenga mapaipi a PVC-U kuti azikhetsa madzi, omwe amapangidwa ndi utomoni wa polyvinyl chloride monga zopangira zazikulu. Iwo anawonjezera ndi zofunika zina ndi kupanga kudzera extrusion processing. Ndi chitoliro chomanga ngalande chokhala ndi mphamvu zambiri, kukhazikika kwabwino, moyo wautali wautumiki komanso magwiridwe antchito okwera mtengo. Itha kugwiritsidwa ntchito pomanga ngalande, chitoliro cha chimbudzi chapaipi ndi chitoliro cha mpweya wabwino.

Ubwino wa chitoliro cha PVC ndi awa:
1. Ili ndi mphamvu yabwino komanso yopondereza komanso chitetezo chachikulu.
2. Kukaniza kwamadzi pang'ono:
Khoma la chitoliro cha PVC ndi losalala kwambiri ndipo kukana kwamadzimadzi ndikochepa kwambiri. Coefficient yake ya roughness ndi 0.009 yokha. Mphamvu yake yoperekera madzi imatha kuchulukitsidwa ndi 20% poyerekeza ndi chitoliro chachitsulo chofananacho ndi 40% kuposa chitoliro cha konkriti.
3. Kukana kwabwino kwa dzimbiri ndi kukana kwa mankhwala:
Mapaipi a PVC ali ndi kukana bwino kwa asidi, kukana kwa alkali, kukana dzimbiri. Sakhudzidwa ndi chinyezi ndi nthaka PH. Palibe chithandizo cha anticorrosive chomwe chimafunikira pakuyika mapaipi. Chitolirochi chimakhala ndi kukana kwa dzimbiri kwa ma inorganic acid, alkali ndi mchere. Ndizoyenera kutulutsa zimbudzi zamakampani ndi zoyendera.
4. Kuthina kwamadzi kwabwino: Kuyika kwa mapaipi a PVC kumakhala ndi kutsekeka kwamadzi kwabwino mosasamala kanthu kuti kumalumikizidwa kapena kulumikizidwa kwa mphete ya rabara.
5. Anti-bite: PVC chitoliro si gwero la zakudya, choncho sichidzakokoloka ndi makoswe. Malinga ndi mayeso omwe a National Health Foundation ku Michigan adachita, makoswe sangathe ngakhale kuluma mapaipi a PVC.
6. Kukana kukalamba kwabwino: Moyo wanthawi zonse wautumiki ukhoza kupitilira 50.
zaka.

Chifukwa chogwiritsira ntchito mapaipi a PVC sikuti ndi zabwino zomwe zili pamwambazi. Kulemera kwake kopepuka kumatha kupulumutsa ndalama zoyendera zamakina olemetsa ndikuchepetsa kwambiri nthawi yoboola mapaipi. Kaya ndi zivomezi kapena zochitika zina, mapaipi a PVC amatha kukhalapo. Izi zimapangitsa chitoliro cha PVC kukhala chothandizira kwambiri.
