Ruzivo rwekugadzira:
Pombi yesimbi yakasimbiswa newaya yakasanganiswa ipombi itsva yepurasitiki yakagadzirwa newaya yakagadzirwa nesimbi. Rudzi urwu rwepombi runonziwo SRTP. Rudzi urwu rutsva rwepombi rwakagadzirwa nesimba rakawanda kuburikidza newaya yesimbi yemhando yepamusoro uye polyethylene yethermoplastic sezvinhu zvakagadziriswa, waya yesimbi yakasimbiswa nepaipi yepurasitiki yepolyethylene, polyethylene ine density yakakwira (HDPE) asmatrix, ine simba rakakwirira reHDPE modified bonding resin richabatanidza furemu yewaya ine mukati nekunze kwe polyethylene ine density yakakwira yakabatana, kuitira kuti ive nemhedzisiro yakanaka yecompound. Pombi yecompound inokunda zvakaipa zvesimbi nepurasitiki, uku ichichengetedza zvakanakira zvese, nekuti simba rayo rakasimba rakafukidzwa nethermoplastic inoenderera mberi.
Pombi yesimbi yakasimbiswa newaya yakasanganiswa, kushandiswa kwezvinhu zvemhando yepamusoro uye tekinoroji yepamusoro yekugadzira, kuitira kuti ive nekushanda kwakasimba kwekumanikidza. Panguva imwe chete, pombi yecomposite ine kuchinjika kwakanaka, yakakodzera mvura yakavigwa kure uye sisitimu yemapaipi egasi. Pombi yepolyethylene electrofuse inoshandiswa pombi yesimbi yakasimbiswa newaya yepolyethylene yakasanganiswa. Pakubatanidza, muviri wekupisa wepombi unoshandiswa kunyungudutsa purasitiki yekunze yepombi nepurasitiki yemukati yepombi, kuitira kuti pombi nepombi zvibatane zvakavimbika.
