Zvinhu zvishanu zvepurasitiki zvakajairika zvewaya netambo

Kunyangwe mhando dze wayauye wayadzakasiyana-siyana, asi chimiro chikuru chezvigadzirwa zvakafanana, zvinhu zvinoshandiswa zvakafanana, zvinhu zvakajairika zvinosanganisira zvinhu zvinofambisa mvura, zvinhu zvinodzivirira, zvinhu zvinodzivirira, zvinhu zvinozadza, nezvimwewo, uye ac.TamboZvichienderana nehunyanzvi hwazvo hwakasiyana zvinogona kukamurwa kuita mapoka maviri, zvinhu zvesimbi, zvakaita se copper aluminum, aluminum alloy, uye zvinhu zvepurasitiki. Common PVC, PE, PP, nezvimwewo, zvinoteverwa ndidzo mhando shanu dzezvinhu zvepurasitiki zvinowanzoshandiswa muwayauye waya.

1. PVC, ndiyo inonyanya kushandiswa mupurasitiki muwaya uye Waya, PVC inowanzo shandiswa pakudzivirira waya netambo, izvi zvinodaro nekuti PVC ine zvinhu zvakawanda zvakanaka zvekudzivirira izvo zvinogona kudzivirira waya netambo mukati, zvakaita sekuti PVC haisi nyore kutsva, haikwanise kukwegura, haikwanise mafuta, haikwanise ngura nemakemikari, haikwanise kubatwa nechinhu, izvi zvinoita kuti ive nemhedzisiro yakanaka yekudzivirira, saka zvinhu zvekudzivirira waya netambo zvinonyanya kuve zvinhu zvePVC.

2. YAKABVISWA(Polyethylene), hunhu hwayo hwepanyama ihwohwo huchena hwakaita sewakisi inopenya, ine kuchinjika kwakanaka, inogona kutambanudzwa kusvika pakureba kwakati, yakareruka kupfuura mvura, haina chepfu, asi kana ichienzaniswa nePVC, polyethylene ine hunhu hwekutsva nyore. Kunyangwe ikabuda mumoto, icharamba ichitsva, polyethylene inewo mhando dzakawanda dzakakura, dzinosanganisira LDPE, MDPE, HDPE, LDPE ndeimwe yemhando dzakaderera, inozivikanwa se low-pressure polyethylene, ine kuchinjika kwakanaka kwazvo. MDPE i medium density polyethylene, inozivikanwa se medium pressure polyethylene, mashandiro ayo uye high density polyethylene zvakafanana. HDPE inozivikanwawo se high pressure polyethylene, mashandiro ayo akazara akakwirira, kunyanya kudzivirira kupisa uye simba remakanika zvese zvakagadziridzwa. Polyethylene ine hunhu hwakanaka hwekudzivirira magetsi uye inoshandiswa zvakanyanya mukudzivirira tambo dzekutaurirana.

3. Eva(ethylene - vinyl acetate copolymer), ipurasitiki yakaita serabha, mashandiro ayo uye huwandu hwayo hwevinyl acetate (VA) zvine hukama hwakanaka, huwandu hweVA hudiki hwakaita sepolyethylene, huwandu hwayo hwakakwira hwakaita sehunhu hwerabha, EVA ine kusimba kwakanaka uye kuramba kupisa kwakaderera, kuramba makemikari. Kunyangwe yakasanganiswa neLDPE, inogona kugadzirisa dambudziko rekuti LDPE iri nyore kutsemuka, uye kuramba kukanganiswa, kupfava uye kuomarara, uye kubatana pakati pemuchina nekudzivirira zvinogona kurongeka zvakanaka uye kusimbiswa.

4. PP(Polypropylene), ndiyo ine chikamu chidiki pakati pemapurasitiki anoshandiswa pari zvino, simba remuchina rakawanda, simba rekupisa rakaderera, simba rekuramba rakakwirira, simba rekuparara rakaderera, hunhu hwemvura shoma, PP inogona kukodzera nzvimbo yezvinhu zvinodzivirira kupisa zvine frequency yakawanda.

5. Polyester, rudzi urwu rwezvinhu runoratidzwa nekusabvaruka kwakanyanya, kusapera kwakanyanya, kusachinjika kwakanyanya uye kusasimba kwakanyanya, muganho wepamusoro wekupisa kunoshanda unogona kusvika 1500 degrees Celsius, iyo yakakura kupfuura mamwe marabha ethermoplastic, asi inewo hunhu hwakanaka hwekudzivirira mafuta, kusashanda kwe solvent.

Boying inyanzvi waya mutengesi ane timu ine ruzivo, achipa marudzi ese e waya uye waya yekubatanidzaKana uri kutsvaga waya yakakosha, Boying ine mhinduro yakagadzirirwa iwe.
