Resin: PVC inowanzo shandisa mhando 8 resin, ine kukurumidza gelation kumhanya panguva yekugadziriswa, yakadzikira kupisa tembiricha, yakagadzikana chigadzirwa mhando, uye nyore density control.Mumakore achangopfuura, vagadziri vazhinji vakachinja kuita 5 resin.
Stabilizer: Kusarudzwa kwekudzikamisa, uchifunga nezvekuchengetedzwa kwezvakatipoteredza uye mhedzisiro yakanaka yeinoda isingawanzo kudzika pasi pasi, asi nekuda kwemutengo wakakwira, usingasimudzirwe, ramangwana rine zvinodiwa zvekuchengetedza kwezvakatipoteredza kuwedzera, isingawanzo pasi pasi stabilizer musika ichaunza. tarisiro dzakajeka.Calcium zinc stabilizer ine zinc inopisa dambudziko uye kugadzikana mhedzisiro ishoma uye huwandu hwacho hushoma.Parizvino, iyo inonyanya kushandiswa kana inotungamira munyu stabilizer, foam board nekuda kwe mold cross-section yakafara, iyo inoyerera chiteshi chakareba uye yero furo decomposition kupisa kugadzirwa, iyo stabilizer inofanirwa kuve neyakakura lead yemukati uye yakanaka kugadzikana mhedzisiro. chigadzirwa chinotarisana nezvinetso zvakasiyana-siyana.
Kuvhuvhuta mumiriri: kusarudzwa kweanofuridza mumiriri, kuvhuvhuta mumiriri AC mukuwora kuburitsa kupisa kwakawanda, kuri nyore kutungamira kusvika pakati pechikamu chero, iyo inoda imwe chiyero chechena inovhuvhuta mumiriri, kuora kunoita basa rekunyudza zvakawandisa. simba rekupisa, rinoda huwandu hweanofuridza kuti ive hombe, kuitira kuti uwane yunifomu yekupupa pasina maburi mahombe.
Regulator: furo regulator, kuburikidza nemakore ekutsvagisa nekusimudzira nekuvandudza, iyo tekinoroji yekupupa furo regulator ACR iri kuramba ichikura, uye hunhu hwekuita huri kuramba huchiwedzera kugadzikana.Zvinoenderana neukobvu hwekupupa bhodhi, pepa rinofanira kunge rakagadzirwa nepurasitiki nekukurumidza, uye gobvu bhodhi rinofanirwa kuve plasticized inononoka mhinduro yakasimba inopupuma regulator.
Mafuta ekuzora: Kusarudzwa kwemafuta ekuzora kunotevera musimboti wekutanga, wepakati uye wekupedzisira kudzosa, kuitira kuti zvinhu zvidzivirirwe nemafuta pamatanho ese, uye zvinonamatira kune yakagadzikana kugadzirwa kwenguva refu pasina kushatisa.
Mafuro anobatsira: Kuti uvandudze kunaka kwekupupuma uye chimiro chefuro, shoma shoma yeinopupa inobatsira zinc oxide inogona kuwedzerwa mukugadzirwa, uye shoma shoma yealuminium silicate inogona kuwedzerwa kuitira kuderedza kunaya.
Pigments: Kuti uwane mhedzisiro yakanaka, titanium dioxide uye fluorescent whitening agents inogona kuwedzerwa, uye antioxidants uye ultraviolet absorbers inogona kuwedzerwa kuvandudza mamiriro ekunze.
Filler: Kusarudzwa kwechiedza che calcium carbonate kunogona kuva, pasina kushandiswa kwekasimusi inoshanda, kusarudzwa kwenhamba yepamusoro mesh.
Iyo thermoplastic yakakwira-molecular polymer yakagadzirwa nekumiswa kwepolymerization yevinyl chloride monomer.The molecular formula :- (CH2 – CHCl) n – (N: dhigirii repolymerization, N= 590 ~ 1500).Ndiyo yakanyanya kuwanda mbishi inoshandiswa mukugadzirwa kwepurasitiki.Iine kugadzikana kwakanaka kwekemikari, kusagadzikana kwekuora uye kusagadzikana kwemvura.
