Wedzera zvinosimbisa, mafuta ekuisa muchina uye zvinozadza muPVC, uye mushure mekusanganisa, shandisa chinoburitsa muchina kubvisa mapaipi akaoma, mapaipi ane chimiro chakasarudzika, uye mapaipi ane mativi akasiyana-siyana, anogona kushandiswa semapaipi etsvina, mapaipi emvura yekunwa, macasing ewaya kana ma handrails ematanho. Mapepa ane calender anoiswa pamusoro uye anodzvanywa nekupisa kuti agadzire mapurati akaoma ane ukobvu hwakasiyana-siyana. Maplate anogona kuchekwa kuita maumbirwo aunoda, uye ozobatanidzwa nemhepo inopisa uchishandisa PVC welding rods kugadzira matangi akasiyana-siyana ekuchengetedza asingashandise makemikari, machubhu emhepo uye magaba.
5. PVC zvigadzirwa zvakapfava
Zvishandiso zvekuburitsa zvinhu zvinogona kushandiswa kuburitsa mapombi, tambo, waya, nezvimwewo; michina yekuumba majekiseni inogona kushandiswa kufananidza mhando dzakasiyana dzemaforoma kugadzira masandari epurasitiki, zvigadziko, masiraidhi, matoyi, zvikamu zvemota, nezvimwewo.
6. Zvinhu zvekurongedza zvePVC
Zvigadzirwa zvePVC zvinonyanya kushandiswa mumidziyo yakasiyana-siyana, mafirimu uye mapepa akaomarara ekurongedza. Matangi ePVC anonyanya kushandiswa mukugadzira mvura ine zvicherwa, zvinwiwa, uye mabhodhoro ezvizoro, uye anoshandiswawo mukupakata mafuta akacheneswa. Firimu rePVC rinogona kushandiswa pakubatanidza nemamwe mapolymers kugadzira ma laminates asingadhuri, pamwe chete nezvigadzirwa zvinoonekera zvine hunhu hwakanaka hwekudzivirira. Firimu rePVC rinoshandiswawo mukuputira matiresi, machira, matoyi nezvinhu zvemaindasitiri.
7. Siding neflooring zvePVC
PVC siding inonyanya kushandiswa kutsiva aruminiyamu siding. Kunze kwechikamu chepolyvinyl chloride resin, zvimwe zvikamu zvemataira epasi epolyvinyl chloride zvinhu zvakadzokororwa, manamati, zvinozadza nezvimwe zvikamu, izvo zvinonyanya kushandiswa pasi pezvivakwa zvepanhandare yendege uye pasi rakaoma mune dzimwe nzvimbo.
8. Zvinhu zvevatengi zvePolyvinyl chloride
Bhegi remikwende chigadzirwa chechinyakare chakagadzirwa nepolyvinyl chloride. Polyvinyl chloride inoshandiswa kugadzira matehwe akasiyana-siyana emhando yematehwe emukwende uye zvigadzirwa zvemitambo zvakaita sebasketball, nhabvu nerugby. Inogona zvakare kushandiswa kugadzira mabhandi eyunifomu uye zvishandiso zvekudzivirira zvakakosha. Machira epolyvinyl chloride ezvipfeko anowanzo kuve machira anonyudza (hapana chifukidziro chinodiwa), akadai semachira emvura, mabhurugwa evana, majaketi eganda emhando yemhando yemvura uye mabhutsu akasiyana-siyana emvura. PVC inoshandiswa muzvigadzirwa zvakawanda zvemitambo nezvevaraidzo, zvakaita sematoyi, marekodhi nezvigadzirwa zvemitambo. Matoyi ePVC nezvigadzirwa zvemitambo zvine mwero mukuru wekukura, uye zvine zvakanakira nekuda kwemutengo wakaderera wekugadzira uye nyore kugadzira.
9. Zvigadzirwa zvakaputirwa nePVC
Dehwe rekugadzira rine mubato rinogadzirwa nekuisa PVC pajira kana bepa, wozoriisa mupurasitiki pamusoro pe100°C. Rinogonawo kugadzirwa nekumonera PVC nezvimwe zvinowedzerwa mufirimu kutanga, wozodzvanya ne substrate. Dehwe rekugadzira risina mubato rinonamirwa zvakananga kuita pepa rakapfava rine ukobvu hwakati ne calender, rozodzvanywa ne pattern. Dehwe rekugadzira rinogona kushandiswa kugadzira masutukesi, mabhegi, mabhuku, masofa nema cushion emotokari, pamwe nedehwe repasi, iro rinoshandiswa sezvinhu zvepasi zvezvivakwa.
10. Zvigadzirwa zvefuro zvePVC
Kana PVC yakapfava ikakangwa, huwandu hwakakodzera hwemushonga wefuro hunowedzerwa kuti pave nejira, rinozogadzirwa furo rozogadzirwa kuita purasitiki yefuro, iyo inogona kushandiswa semasiraidhi efuro, masandari, ma insoles, uye zvinhu zvekupakata zvinodzivirira kuvhunduka. Inogona zvakare kushandiswa kugadzira machira ePVC akaomarara asina furo rakawanda nezvinhu zvakaumbwa zvichibva pane zvinobuda, izvo zvinogona kushandiswa panzvimbo pehuni. Imhando itsva yezvinhu zvekuvaka.
11. PVC jira rinoonekera
Wedzera impact modifier uye organotin stabilizer kuPVC, wobva waita pepa rinoonekera mushure mekusanganisa, kuisa purasitiki uye kuisa calender. Inogona kugadzirwa kuita midziyo inoonekera ine madziro matete kana kushandiswa mu vacuum blister packaging ne thermoforming. Ipurasitiki yakanaka kwazvo uye inoshongedza.
12. Zvimwe
Masuo nemahwindo zvinogadzirwa nezvinhu zvakaoma. Mune dzimwe nyika, zvave zvichishandiswa mumusika wemasuo nemahwindo pamwe chete nemasuo nemahwindo emapuranga, mahwindo earuminiyamu, nezvimwewo; zvinhu zvemapuranga zvenhema, zvinhu zvekuvaka zvinotsiva simbi (kuchamhembe, kumahombekombe); midziyo isina chinhu.
