Sumo yechigadzirwa:
Kuyerera kwemvura yePVC-Upombiinoshandisa polyvinyl chloride resin sechinhu chikuru chekugadzira, inowedzera zvimwe zvinodiwa, uye inoumbwa nekugadzira extrusion. Imhando yezvigadzirwa zvemapombi emvura ane tekinoroji yakakura uye yave ichishandiswa zvakanyanya kumba nekune dzimwe nyika. Chigadzirwa ichi chine zvakanakira zvekugara kwenguva refu, kuramba ngura, nezvimwewo, izvo zvisingaenzaniswi nemapombi esimbi akaumbwa; chakareruka pakuvaka, chiri nyore kubata nekuisa, uye chiri nyore kubatanidza. Chinoshandiswa zvakanyanya mukugadzira mvura yemumba, kuchenesa makemikari, uye kuchenesa mvura yemvura.

Zvimiro:
Chigadzirwa ichi chine zvakanakira zvekugara kwenguva refu uye kuramba ngura kwemapaipi esimbi; chakareruka pakuvaka, chiri nyore kubata nekuisa, uye chiri nyore kubatanidza. Chinoshandiswa zvakanyanya mukugadzira mvura yekuvaka, kuchenesa makemikari, uye kuchenesa mvura yemvura.
1. Kuomarara kwepaipi uye simba rekudhonza zvakanaka, uye chinhu chekuchengetedza chepombipombiyakakwira.
2. Mutengo wakaderera, hupenyu hwebasa hurefu, hupenyu hwebasa hwenguva dzose hunogona kusvika makore anopfuura makumi mashanu, pasina chikonzero chekugadzirisa nekugadzirisa nguva dzose.
3. Pombi iyi inodzivirira ngura zvakanyanya ku inorganic acids, alkalis, uye munyu. Yakakodzera kuburitswa kwetsvina yemumaindasitiri uye kutakurwa kwayo. Haina ngura kana kukura, saka hapana ngura kana kuderera mukati.
Hazvisi nyore kuvharika, uye rusvingo rwekunze haruzosvibiswi nekuda kwengura yepombi, kuona runako rwechivako.
4. Kukwana kwepombi yekukweshana kudiki, kuyerera kwemvura kwakatsetseka, hakusi nyore kuvharika, uye basa rekugadzirisa diki.
5. Chinhu chacho chine oxygen index yakakwira uye chinozvidzima chega.
6. Kuwanda kwepaipi iri mumutsara mudiki, uye huwandu hwekuchinja hunokanganisa tembiricha hudiki. Kufambiswa kwemhepo ne elastic modulus kudiki, uye kushanda kwekudzivirira kutonhora kuri nani pane kwepaipi dzemvura dzakagadzirwa nesimbi.
7. Mapaipi nezvishandiso zvakabatana neglue, nzira yekuvaka iri nyore, mashandiro acho ari nyore, uye kushanda zvakanaka kwekuisa kwacho kwakanyanya.
8. Haina chepfu, haina munyu une chepfu we lead nemamwe makemikari ane chepfu, uye haina njodzi kumuviri wemunhu.
