Polyvinyl chloride (PVC) ipolymer yakagadzirwa nepolymerization yevinyl chloride monomer (VCM) pamberi pevanotangisa senge peroxides uye azo komisheni kana nemaitiro emahara radical polymerization pasi pekuita kwechiedza kana kupisa.PVC chinhu chepolymer chinoshandisa atomu yechlorine kutsiva atomu yehydrogen mupolyethylene, uye vinyl chloride homopolymers uye vinyl chloride copolymers dzinonzi pamwe chete vinyl chloride resins.
PVC molecular chain dzine yakasimba polar chlorine maatomu ane high intermolecular forces, anoita kuti zvigadzirwa zvePVC zviome, zviome, uye zvine mutsindo, uye zvine murazvo wakanyanya kudzikira (flame retardancy inoreva chivakwa chine chinhu kana icho chinhu chine mushure mekurapwa. zvakanyanya kunonoka kupararira kwemurazvo);zvisinei, dielectric yayo inogara uye dielectric kurasikirwa angle tangent kukosha kwakakura kupfuura iyo yePE.
PVC resin ine nhamba diki yezvisungo zvakapetwa kaviri, cheni dzine matavi uye zvisaririra zvekutanga zvakasiiwa mupolymerization reaction, pamwe nechlorine nehydrogen maatomu pakati pemaatomu ecarbon ari padyo, ayo anobviswa nyore nyore, zvichikonzera kuparara kwePVC nyore pasi pechiito. yechiedza nekupisa.Nokudaro, zvigadzirwa zvePVC zvinoda kuwedzera zvinogadzirisa kupisa, zvakadai se calcium-zinc heat stabilizer, barium-zinc heat stabilizer, lead salt heat stabilizer, organic tin stabilizer, nezvimwewo.
Main applications
PVC inouya nenzira dzakasiyana-siyana uye inogona kugadziriswa nenzira dzakasiyana-siyana, kusanganisira kudzvanya, kuburitsa, kubaya jekiseni, uye kuvhara.PVC mapurasitiki anowanzo shandiswa mukugadzira mafirimu, matehwe ekugadzira, insulation yewaya netambo, zvigadzirwa zvakaomarara, pasi, fenicha, midziyo yemitambo, nezvimwe.
Zvigadzirwa zvePVC zvinowanzoiswa muzvikamu zvitatu: yakaoma, semi-yakaomarara uye yakapfava.Zvigadzirwa zvakaomesesa uye semi-zvakaomesesa zvinogadziriswa pasina kana nediki diki yeplasticizer, nepo zvinyoro zvigadzirwa zvinogadziriswa nehuwandu hukuru hwepurasitiki.Mushure mekuwedzera mapurasitiki, tembiricha yegirazi inogona kudzikiswa, izvo zvinoita kuti zvive nyore kugadzirisa pane yakaderera tembiricha uye inowedzera kuchinjika uye plasticity yeketani yemamorekuru, uye inoita kuti zvikwanise kugadzira zvigadzirwa zvinyoro zvinochinjika pane tembiricha yekamuri.
1. PVC profiles
Inonyanya kushandiswa kugadzira magonhi nemahwindo uye zvinhu zvinochengetedza simba.
2. PVC mapaipi
Mapaipi ePVC ane marudzi mazhinji, kuita kwakanakisa uye kuwanda kwekushandisa, uye anotora chinzvimbo chakakosha mumusika.
3. PVC mafirimu
PVC inogona kugadzirwa kuita firimu rakajeka kana rine ruvara rwehukobvu hwakatsanangurwa uchishandisa karenda, uye firimu rinogadzirwa nenzira iyi rinonzi calendered film.PVC granular raw materials inogonawo kufuridzirwa mufirimu uchishandisa blow molding machines, uye firimu rinogadzirwa nenzira iyi rinonzi blow molding film.Iyo firimu inogona kushandiswa kune zvinangwa zvakawanda uye inogona kugadziriswa kuva mabhegi, raincoats, tablecloths, maketeni, inflatable toys, nezvimwewo nekucheka uye kupisa-kuvhara nzira.Mafirimu akawanda akajeka anogona kushandiswa kuvaka greenhouses uye epurasitiki greenhouses, kana kushandiswa semafirimu epasi.
4. PVC board
Yakawedzerwa ne stabilizer, lubricant uye filler, uye mushure mekusanganisa, PVC inogona kubudiswa mumapombi akasiyana-siyana akaomarara, mapaipi akaumbwa uye mapaipi ane marara ane extruder, uye anoshandiswa sepipepipe, pombi yemvura yekunwa, waya yemagetsi casing kana staircase handrail.Mashizha akaremerwa anoputirana uye anopisa akatsikirirwa kuita mapepa akaomarara emhando dzakasiyana siyana.Mashizha anogona kutemwa kuita maumbirwo aidiwa obva asungwa nemhepo inopisa achishandisa PVC welding rods mumatangi ekuchengetedza makemikari akasiyana-siyana, madhairi nemidziyo, nezvimwe.
5. PVC zvinyoro zvigadzirwa
Kushandisa extruder, inogona kubudiswa muhosi, tambo, waya, nezvimwewo;uchishandisa muchina wekuumba jekiseni une mold dzakasiyana siyana, unogona kugadzirwa kuva shangu dzepurasitiki, soli dzeshangu, masiraibhu, matoyi, auto zvikamu, nezvimwe.
6. PVC kurongedza zvinhu
PVC zvigadzirwa zvekurongedza zvakanyanya kune akasiyana midziyo, firimu uye hard sheet.PVC midziyo inonyanya kugadzirwa yemvura yemaminerari, zvinwiwa, mabhodhoro ekuzora, asiwo nekunatswa kwemafuta ekurongedza.
7. PVC siding uye pasi
PVC siding inonyanya kushandiswa kutsiva aluminium siding, PVC floor tiles, kunze kwechikamu chePVC resin, zvimwe zvikamu zvacho zvinogadzirwazve zvinhu, zvinonamira, mafirita uye zvimwe zvinhu, zvinonyanya kushandiswa muairport terminal pasi nedzimwe nzvimbo dzakaoma. pasi.
8. PVC zvigadzirwa zvevatengi
Zvigadzirwa zvePVC zvinogona kuwanikwa kwese kwese muhupenyu hwedu hwezuva nezuva.PVC inoshandiswa kugadzira akasiyana matehwe ematehwe emabhegi, zvigadzirwa zvemitambo zvakaita sebasketball, bhora renhabvu uye rugby mabhora.Inoshandiswawo kugadzira yunifomu uye mabhandi emidziyo yekudzivirira yakakosha.Machira ePVC ezvipfeko anowanzo kunwa machira (hapana coating inodiwa) senge ponchos, bhurugwa revana, majaketi ematehwe ekugadzira uye bhutsu dzemvura dzakasiyana.PVC inoshandiswawo mune zvakawanda zvemitambo uye zvevaraidzo zvigadzirwa sematoyi, marekodhi uye zvinhu zvemitambo.
