PVC dehwe chinhu chekugadzira, chinonziwo chakagadzirwa dehwe kana kutevedzera dehwe. Yakagadzirwa ne polyvinyl chloride (PVC) resin uye zvimwe zvinowedzera kuburikidza neakatevedzana ekugadzirisa matekiniki, uye ine chitarisiko chakafanana nedehwe uye kunzwa. Zvisinei, kana zvichienzaniswa nematehwe echokwadi, PVC yematehwe inoenderana nemhoteredzo, iri nyore kuchenesa, isingapfeki, uye inodzivirira mamiriro ekunze. Naizvozvo, yakashandiswa zvakanyanya mufenicha, mota, zvipfeko, mabhegi nemimwe minda.
Chekutanga pane zvese, iyo mbishi yePVC yematehwe inonyanya kuve polyvinyl chloride resin, inova yakajairika plastiki zvinhu zvine purasitiki yakanaka uye kusagadzikana kwemamiriro ekunze. Paunenge uchigadzira PVC dehwe, zvimwe zvekubatsira zvakaita seplasticizers, stabilizers, fillers, pamwe nepigment uye pamusoro pekurapa vamiririri vanowedzerwa kugadzira akasiyana masitayipi uye kuita kwePVC yematehwe zvinhu kuburikidza nekusanganisa, calendering, coating uye mamwe maitiro.
Chechipiri, PVC dehwe rine zvakawanda zvakanakira. Chokutanga pane zvose, maitiro ayo ekugadzira ari nyore uye mari yacho yakaderera, saka mutengo wakaderera, unogona kuzadzisa zvido zvekushandiswa kwehuwandu. Chechipiri, PVC yedehwe ine yakanaka kupfeka kuramba uye kuramba mamiriro ekunze, haisi nyore kuchembera kana kukanganisa, uye ine hupenyu hurefu hwebasa. Chechitatu, PVC dehwe iri nyore kuchenesa, nyore kuchengeta, haisi nyore kusvibisa, uye nyore kushandisa. Pamusoro pezvo, PVC dehwe rinewo zvimwe zvinhu zvisingapindi mvura, izvo zvinogona kuramba kukukurwa kwemvura kusvika kumwero wakati, saka zvakare yakashandiswa zvakanyanya mune dzimwe nguva zvinoda kusapinda mvura.
Nekudaro, PVC yematehwe inewo zvimwe zvayakaipira. Kutanga, kana ichienzaniswa nedehwe rechokwadi, PVC yematehwe ine mhepo isina kunaka inopindika uye inowanzoita kusagadzikana panguva yekushandiswa kwenguva refu. Chechipiri, kuchengetedza kwezvakatipoteredza kwePVC dehwe kune gakava zvakare, nekuti zvinhu zvinokuvadza zvinogona kuburitswa panguva yekugadzira uye kushandiswa, izvo zvinokanganisa nharaunda uye hutano hwevanhu.
Yetatu, PVC dehwe rine hurombo hunyoro hwepurasitiki uye haisi nyore kugadzira kuita yakaoma-mativi matatu-dimensional zvimiro, saka inogumira mune dzimwe nguva dzakakosha dzekushandisa.
Kazhinji, PVC yematehwe, seyakagadzirwa zvinhu, yakashandiswa zvakanyanya mufenicha, mota, zvipfeko, mabhegi nemimwe minda. Kunaka kwayo kwakadai sekuramba kupfeka, kusamira kwemamiriro ekunze uye kuchenesa kuri nyore kunoita kuti ive inotsiva dehwe rechokwadi. Zvisinei, zvikanganiso zvayo zvakadai sekushaya simba kwemhepo uye kuchengetedzwa kwezvakatipoteredza kunoda kuti titeerere kana tichiishandisa, uye sarudza zvinhu zvakakodzera kuti tisangane nezvinodiwa zvakasiyana.
